to work beginning at the site. If Contractor fails to meet a milestone, contractor shall submit an
updated schedule subject to Owner approval and demonstrate how the remaining milestones will be
met. The Owner may order work shut down or suspended for nonconformance with the approved
schedule (See Paragraph G. below)
G. Milestones (minimum required items)
(1) Rolland Moore Parking Lot and Bridge – Completed by March 15, 2007
H. The Contractor may voluntarily shut down or suspend work due to conditions beyond his control
provided a minimum of 24 hours notice is provided to the Owner together with the reasons for subject
suspension of work. The Contractor shall leave the project conditions in such a way so as not to cause
a public nuisance or a threat to public safety. Neither remobilization costs nor additional time will be
allowed for such suspension unless agreed to in writing in advance.
I. The Owner or Engineer may order work shut down or suspended for such nonconformance issues as
unsafe conditions, nonconformance with schedule, cause of public nuisance, unnecessary private
property disturbance, materials and labor unsuited to the task, nonconformance to technical
specifications, failure to comply with permits, etc. The Owner or Engineer will give a written warning
to the Contractor with a specified deadline during which time the Contractor shall remedy the cause(s)
described on the warning. Failure to do so shall justify the Owner or Engineer to order work shut down
City of Fort Collins SECTION 01310 – CONSTRUCTION SCHEDULES
Park Planning & Development Division Page 2 of 4
or suspended. Such shutdown will not be compensated by cost reimbursement or time schedule
adjustment.
J. Failure to promptly execute the approved schedule in the judgment of the Owner will result in a written
warning submitted to the Contractor explaining the specific compliance needed. Failure of the
Contractor to remedy the noted items may be considered a breach of contract possibly leading to work
shutdown for cause or contract termination.
1.02 Format and Submissions
A. Prepare Construction and Procurement schedules in a graphic format suitable for displaying schedule
and actual progress.
B. Submit two copies of each schedule to owner for review. Owner will return one copy to contractor with
revisions suggested or necessary for coordination of the Work with the needs of Owner or others.
1.03 Progress Revisions
A. A schedule update shall be submitted to the Owner at each weekly progress meeting that will reflect
work performed in the previous week and the upcoming two-(2) weeks. Schedule updates shall not
change any Contract times.
B. A complete schedule update shall be submitted with each application for progress payment.
C. Show changes occurring since previous submission.
1. Actual progress of each item to date.
2. Revised projections of progress and completion.
D. Provide a narrative report as needed to define:
1. Anticipated problems, recommended actions, and their effects on the schedule.
2. The effect of changes on schedules of other work.
1.04 Modifications to Time of Completion in the Approved Schedule
A. The date of beginning and the times for completion of the work are essential conditions of the Contract
Documents and the work embraced shall be commenced on a date specified in the Notice to Proceed.
The Contractor will proceed with the work at such rate of progress to ensure full completion within the
contract time. It is expressly understood and agreed, by and between the Contractor and the Owner
that the contract time for the completion of the work described herein is a reasonable time, taking into
consideration the climatic and other factors prevailing in the locality of the work.
Every effort shall be made by the Contractor to complete the project within the "Contract Time" shown
in the proposal. The "Contract Time" anticipates a “Normal” weather and climate condition in and
around the vicinity of the Project site during the times of year that the construction will be carried out.
Extensions of time based upon weather conditions shall be granted only if the Contractor demonstrates
clearly that such conditions were "unusually severe," would not have been reasonably anticipated, and
that such conditions adversely affected the Contractor’s work and thus required additional time to
complete the work.
B. The following specifies the procedure for the determination of time extensions for unusually severe
weather. The listing below defines the anticipated number of calendar days lost to adverse weather for
each month and is based upon National Oceanic and Atmospheric Administration (NOAA) or similar
data for the geographic location of the project.
Monthly Anticipated Calendar Days Lost to Adverse Weather Conditions

Park Planning & Development Division Page 3 of 4
JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
(7) (4) (4) (4) (6) (3) (4) (2) (3) (3) (2) (5)
The above schedule of anticipated adverse weather will constitute the base line for monthly (or portion
thereof) weather time evaluations. Upon acknowledgment of the Notice to Proceed and continuing
throughout the contract on a monthly basis, actual adverse weather days and the impact of adverse
weather days that delay the work will be recorded on a day-to-day basis. It is assumed that the work
will be carried out Mondays through Fridays (holidays excluded) unless an approved construction
schedule or written authorization from the Owner indicates otherwise. The number of days of delayed
work due to adverse weather or the impact thereof will then be compared to the monthly adverse
weather schedule above.
An actual adverse weather day must prevent work for 50 percent or more of the Contractor’s workday,
delay work critical to the timely completion of the project, and be documented by the Contractor. The
City Representative observing the construction shall determine on a daily basis whether or not work
can proceed or if work is delayed due to adverse weather or the effects thereof. The Contractor shall
notify the Construction Coordinator in writing of any disagreement as to whether or not work can
proceed on a given date, within 2 calendar days of that date. The Owner will use the above written
notification in determining the number of working days for which work was delayed during each
month.
C. At the end of each month, if the number of working days for which work was delayed due to adverse
weather exceeds that shown in the above schedule, a Change Order will be executed which increases
the Contract Time. The number of workdays delayed due to adverse weather or the impact thereof will
then be converted to Calendar Days based on the contract completion day and date. This conversion
assumes a 5-day work week, Mondays through Fridays, holidays excepted; should the Contractor have
authorization to work weekends and/or holidays, then the method of conversion of workdays to
calendar days would take this into consideration. The contract time period will then be increased by the
number of calendar days calculated above and a new contract completion day and date will be set.
D. The Contractor’s schedule must reflect the above-anticipated adverse weather delays on all weather-
dependent activities.
E. While extensions of time shall be granted for "unusually severe" weather or climate conditions, the
Owner shall make no monetary compensation for any costs to the Contractor arising out of such delays.
The Contractor shall comply with the portions of the Contract Documents relating to his project
schedule and amendments thereto which result from the "unusually severe" weather condition.
F. Breakdowns in equipment or lack of performance by the Contractor will not be considered justification
for an extension of time. Liquidated damages will be assessed as delineated elsewhere.
G. The Contractor shall not be charged with liquidated damages or any excess cost when the delay in
completion of the work is due to the following, and the Contractor has promptly given written notice of
such delay to the Owner or Engineer.
1. To any preference, priority, or allocation order duly issued by the Owner.
2. To unforeseeable causes beyond the control and without the fault or negligence of the Contractor,
including but not restricted to, acts of God, or of the public enemy, acts of the Owner, acts of
another Contractor in the performance of a contract with the Owner, fires, floods, epidemics,
quarantine restrictions, strikes, freight embargoes, and abnormal and unforeseeable weather as
provided above; and
3. To any delays of Subcontractors occasioned by any of the causes specified in paragraphs 1 and 2,
above.

A. Poor foundation material for any of the work shall be removed, by the CONTRACTOR, as
directed by the ENGINEER. The CONTRACTOR will be compensated for removal and
replacement of such materials in accordance with Muck Excavation.
The CONTRACTOR is cautioned that construction equipment may cause the natural soils to
pump or deform while performing excavation work inside and on footings, structural floor slabs,
or other structure foundation areas.
Spring Canyon Community Park SECTION 02301 – EARTHWORK
Page 5 of 7
Foundation materials which are: a) saturated by either surface or subsurface flows due to the lack
of adequate water control or dewatering work by the CONTRACTOR; b) frozen for any reason;
or, c) that are disturbed by the CONTRACTOR’s work or caused to become unacceptable for
foundation material purposes by means of the CONTRACTOR’s equipment, manpower, or
methods of work shall be removed and replaced by the CONTRACTOR at his expense.
Dewatering should not be conducted by pumping from inside footing, structural floor slab, or
other structure foundation limits. This may decrease the supporting capacity of the soils.
Care should be taken when excavating the foundations to avoid disturbing the supporting
materials. Excavation by either hand or careful backhoe soil removal, may be required in
excavating the last few inches of material to obtain the subgrade of any item of the concrete work.
Any over-excavated subgrades that are due to the CONTRACTOR’s actions, shall be brought
back to subgrade elevations by the CONTRACTOR and at his expense in the following manner:
1. For over-excavations of 2 inches or less, either: Backfill and compact with an approved
granular materials; backfill with 1/2 inch crushed rock; or fill within concrete at the time of
the appurtenant structure concrete pour.
2. For over-excavations greater than 2 inches, backfill and compact with an approved granular
material.
All granular footings, structural floor slabs, or other structure areas shall be compacted with a
vibratory plate compactor prior to placement of concrete, reinforcing, or bedding materials.
B. Backfill, and fill within 3 feet adjacent to all structures and for full height of the walls, shall be
selected non-swelling material. It shall be granular, well graded, and free from stones larger than
2 inches. Material may be job excavated, but selectivity will be required as determined by the
ENGINEER. Refer to the Plans for job specific requirements. Stockpiled material, other than
topsoil from the excavation shall be used for backfilling unless an impervious structural backfill is
specified. The backfill material shall consist of either clean on-site granular materials free of
stones larger than 2 inches in diameter with no more than 20% passing the No. 200 sieve, or
equivalent imported materials. All backfill around the structures shall be consolidated by
mechanical tamping. The material shall be placed in 6-inch loose lifts within a range of 2% above
to 2% below the optimum moisture content and compacted to 95% of Maximum Standard Proctor
Density (ASTM D698) for sand soils, or to 75% relative density as determined by the relative
density of cohesionless soils test, ASTM D4253.
When specified on the Drawings or as required by the ENGINEER, Class I structural backfill
shall meet the following gradation requirements:
Sieve Size
% by Weight Passing
Square Mesh Sieves
2-Inch 100
No. 4 30 – 100
No. 50 10 – 60
No. 200 5 – 20
In addition, this material shall have a liquid limit not exceeding 35 and a plasticity index of not
over 6.
Impervious structural backfill, where shown or specified, shall consist of material having 100%
finer than 2 inches in diameter and a minimum of 30% passing a No. 200 U.S. Standard Sieve.
The material shall be placed in 6-inch loose lifts within a range of 2% above to 2% below the
optimum moisture content and compacted to 95% of Maximum Standard Proctor Density for
cohesive soils as determined by ASTM D698.

City of Fort Collins Section 07900 – Joint Sealers
Park Planning & Development Division Page 3 of 5
B. Acceptance: Beginning of installation means acceptance of existing conditions.
3.02 Preparation
A. Preparation of Surfaces
1. Clean surfaces in accordance with manufacturer s recommendations.
2. Mask edges, if required to protect adjoining surfaces and produce a straight finish
line.
3. Clean joint surfaces immediately before installation of sealant. Remove dirt, insecure
coatings, moisture and other substances which would interfere with bond of sealant.
4. Do not proceed with installation of sealant over joint surfaces which have been painted,
lacquered, waterproofed or treatead with water repellent or other treatment of
coating. Remove coating or treatment joint surfaces before installing sealant.
5. Each concrete masonry joint surfaces to remove excess alkalinity unless sealant
manufacturer s printed instruction indicates that alkalinity does not interfere with
sealant bond and performance. Etch with 5% solution of muriatic acid, neutralize with
diluted ammonia solution, rinse thoroughly with water and allow to dry before
sealant installation.
B. Priming: If required, prime surfaces which are to be caulked with manufacturer s recommended or
standard primer, after the surfaces have been prepared as specified. Before use, check primers for
discoloration and dirt pick-up on adjacent surfaces. If staining occurs, after exposure, take
adequate measures to prevent the primer from being applied over the face of adjacent porous
materials by masking or other suitable measures.
C. Joint Backing:
1. Joints shall be of depth necessary to provide for the specified allowable thickness of
sealant and also the required backing where and as specified. Provide backing of extent
and type as specified and required to provide for the allowable depth of the sealant.
2. Back-up Materials for Sealants: Non-staining, compatible with the sealant and primer,
shall be of a resilient nature and as recommended by the manufacturer of the sealant.
Size and shape of the backing shall be as required by the width of the joint and specified.
Do not use materials impregnated with il, solvents, or bituminous materials.
3. Compress backing material a minimum of 30% when inserted in the joint. Backing
material for the upper portion of joint shall be a round rod or semi-circular in cross-
section with the arc in contact with the sealant.
D. Bond Breaker Tape: Install where indicated and as required by manufacturer s recommendations
to ensure that sealants will perform properly.
3.03 Application
A. Exterior Metal Sills: Set in full bed of polyurethane sealant.
B. Thresholds: Set in full bed of latex acrylic sealant.
C. Caulk Joints:
1. Apply sealants in continuous beads without open joints, voids, or air pockets, using a
ratchet hand gun or mechanical powered gun.
2. Confine sealants to joint areas with masking tapes or other precautions. Apply
compounds in concealed compression joints accurately so that excess compound will not
extrude from joints.
City of Fort Collins Section 07900 – Joint Sealers
Park Planning & Development Division Page 4 of 5
3. Remove excess compound or sealant promptly as work progressess, and clean adjoining
surfaces.
4. In rough surfaces or joints of uneven widths, install sealant, well back into joint. Recess
equal to width of joint, or 3/8" minimum at masonry.
5. Use anti-tack agent where necessary to protect freshly applied sealant from public traffic
and dirt.
6. Slightly recessed joints as to facilitate a painter s line. Handtool and finish joints
throughout construction.
7. Comply with manufacturer s printed instructions and specifications.
D. Concrete Paving Expansion Joints: Cut expansion joint filler down to allow joint depth equal to
75% of joint width, but neither more than 0.625" deep nor less than 0.375" deep. Seal over
expansion joint filler with poured sealant.
E. Workmanship: Employ only proven installation techniques, which will ensure that sealants will be
deposited in uniform, continuous ribbons without gaps or air pockets, with complete wetting of
the joint bond surfaces equally on opposite sides. Except as otherwise indicated, fill sealant rabbet
to a slightly concave surface, slightly below adjoining surfaces. Where horizontal joints are
between a horizontal surface and a vertical surface, fill joint to form a slight cove, so that joint will
not trap moisture and dirt.
F. Joint Sizes: Install sealants to depths as indicated or, as recommended by the sealant manufacturer
but within the following general limitations:
1. For normal moving joints sealed with elastomeric sealants but not subject to traffic, fill
joints to a depth equal to 50% of joint width, but not more than 1/2" deep or less than
1/4" deep.
2. For joints sealed with non-elastomeric sealants and caulking compounds, fill joints to a
depth in the range of 75% to 125% of joint width.
G. Spillage:
1. Do not allow sealants or compounds to overflow or spill onto adjoining surfaces, or to
migrate into the voids of adjoining surfaces. Use masking tape or other precautionary
devices to prevent staining of adjoining surfaces, by either the primer/sealer or the
sealant.
2. Remove excess and spillage of compounds promptly as the work progresses. Clean the
adjoining surfaces by whatever means may be necessary to eliminate evidence of
spillage. Do not damage the adjoining surfaces or finishes.
3.04 FIELD QUALITY CONTROL
A. Samples: Where directed by the Architect, cut out and remove a total of three samples consisting
of the undisturbed sealant and back-up material from the joint. Samples shall be 6" in length.
Reseal cut out areas with the same materials.
3.05 CURING, PROTECTION AND CLEANING
A. Curing: Cure sealants and caulking compounds in compliance with manufacturer s instructions
and recommendations, to obtain high early bond strength, internal cohesive strength and surface
durability.
B. Protection:
City of Fort Collins Section 07900 – Joint Sealers
Park Planning & Development Division Page 5 of 5
1. Advise the General Contractor of procedures required for the protection of sealants
during the construction period, so that they will be without deterioration or damage (other
than normal weathering) at the time of acceptance.
C. Cleaning:
1. Protect surfaces from damage. Clean soiled surfaces immediately. Replace with
new material any damaged material which cannot be cleaned with new material.

PART 1 - SITE INVESTIGATIONS AND REPRESENTATION
1.01 General Investigations
A. The Contractor acknowledges that he has satisfied himself as to the nature and location of the work, the
general and local conditions, particularly those bearing upon access to the site; handling, storage, and
disposal of materials; availability of water, electricity and roads; uncertainties of weather, or similar
physical conditions at the site; the conformation and conditions of the ground; the equipment and
facilities needed preliminary to and during the execution of the work; and all other matters which can
in any way affect the work or the cost thereof under this Contract.
1.02 Soil Conditions
A. The Contractor further acknowledges that he has satisfied himself as to the character, quality and
quantity of surface and subsurface materials to be encountered from his inspection of the site and from
reviewing any available records of exploratory work furnished by the Owner or included in these
Documents. Failure by the Contractor to acquaint himself with the physical conditions of the site and
all the available information will not relieve him from responsibility for properly estimating the
difficulty or cost of successfully performing the work.
1.03 Contractor Representation
A. The Contractor warrants that as a result of his examination and investigation of all the aforesaid data
that he can perform the work in a good and workmanlike manner and to the satisfaction of the Owner.

the Contract and (2) the Contract expressly provides that the responsibility therefore is assumed by the
Owner.
PART 2 - INFORMATION ON SITE CONDITIONS
2.01 General
Any information obtained by the Engineer regarding site conditions, subsurface information,
groundwater elevations, existing construction of site facilities, and similar data will be available for
inspection, as applicable, at the office of the Engineer upon request. Such information is offered as
supplementary information only. Neither the Engineer nor the Owner assumes any responsibility for
the completeness or interpretation of such supplementary information.
A. Differing Subsurface Conditions:
1. In the event that the subsurface or latent physical conditions are found materially different from
those indicated in these Documents, and differing materially from those ordinarily encountered and

Park Planning & Development Division Page 1 of 4
DIVISION 1
SECTION 01310 - CONSTRUCTION SCHEDULES
PART 1 - GENERAL
1.01 General
A. It is the intent of the Owner to begin construction on approximately January 2007. The signing of the
contract and issuance of a Notice to Proceed will be completed promptly to accomplish that objective.
The Notice to Proceed will authorize the Contractor to begin project administration and construction
work on the site. Construction work shall not begin on site prior to the pre-construction conference.
B. The Contractor shall complete all work, including cleanup of the site by “Substantial Completion” date,
specified in the Agreement, subject to the "Liquidated Damages" provision described under
"Instructions to Bidders."
C. Delays during project contract period outside control of the Contractor are subject to time extension
consideration but not financial compensation unless such delay is significant enough to reasonably
require Owner initiated work suspension (demobilization) as determined in the field by the Owner at
the time of occurrence. See Paragraph 1.04 for requirements for modifying the Contract Time due to
weather delays.
D. Contractor shall plan and schedule his own work effort (personnel, equipment and material) to
complete the project satisfactorily within the project time limits. Such schedule shall be in general
conformance with the schedule submitted at the pre-construction conference. This includes the
requirement that the Contractor conduct his operations to enable a shift of work effort from one part of
the project to another to reasonably accommodate unexpected delays, and to conduct his daily
operations so as to not create a public nuisance including but not limited to access or traffic
obstruction, dust and mud generation, work outside of construction limits, noise, unsatisfactory cleanup
or site restoration, unacceptable equipment/materials staging, flooding, etc. No work is to begin at the
site until City's acceptance of the Construction Schedule.
E. Contractor shall prepare and submit a Critical Path Method (CPM) schedule. The schedule shall show
all work completed within the contract time and shall cover the time from the date of Notice to Proceed
to the completion date. Contractor shall use Microsoft Project 2000 or approved equivalent to develop
and manage the CPM schedule.
F. Schedule shall include milestones that demonstrate the Contractor’s approach to completing the project
within project time limits. Milestones shall be of sufficient number to indicate regular progress of
work and shall identify major components of the work. Milestones are subject to Owner approval prior
to work beginning at the site. If Contractor fails to meet a milestone, contractor shall submit an
updated schedule subject to Owner approval and demonstrate how the remaining milestones will be
met. The Owner may order work shut down or suspended for nonconformance with the approved
schedule (See Paragraph G. below)
G. Milestones (minimum required items)
(1) Rolland Moore Parking Lot and Bridge – Completed by March 15, 2007
H. The Contractor may voluntarily shut down or suspend work due to conditions beyond his control
provided a minimum of 24 hours notice is provided to the Owner together with the reasons for subject
suspension of work. The Contractor shall leave the project conditions in such a way so as not to cause
a public nuisance or a threat to public safety. Neither remobilization costs nor additional time will be
allowed for such suspension unless agreed to in writing in advance.
I. The Owner or Engineer may order work shut down or suspended for such nonconformance issues as
unsafe conditions, nonconformance with schedule, cause of public nuisance, unnecessary private
property disturbance, materials and labor unsuited to the task, nonconformance to technical
specifications, failure to comply with permits, etc. The Owner or Engineer will give a written warning
to the Contractor with a specified deadline during which time the Contractor shall remedy the cause(s)
described on the warning. Failure to do so shall justify the Owner or Engineer to order work shut down
City of Fort Collins SECTION 01310 – CONSTRUCTION SCHEDULES
Park Planning & Development Division Page 2 of 4
or suspended. Such shutdown will not be compensated by cost reimbursement or time schedule
adjustment.
J. Failure to promptly execute the approved schedule in the judgment of the Owner will result in a written
warning submitted to the Contractor explaining the specific compliance needed. Failure of the
Contractor to remedy the noted items may be considered a breach of contract possibly leading to work
shutdown for cause or contract termination.
1.02 Format and Submissions
A. Prepare Construction and Procurement schedules in a graphic format suitable for displaying schedule
and actual progress.
B. Submit two copies of each schedule to owner for review. Owner will return one copy to contractor with
revisions suggested or necessary for coordination of the Work with the needs of Owner or others.
1.03 Progress Revisions
A. A schedule update shall be submitted to the Owner at each weekly progress meeting that will reflect
work performed in the previous week and the upcoming two-(2) weeks. Schedule updates shall not
change any Contract times.
B. A complete schedule update shall be submitted with each application for progress payment.
C. Show changes occurring since previous submission.
1. Actual progress of each item to date.
2. Revised projections of progress and completion.
D. Provide a narrative report as needed to define:
1. Anticipated problems, recommended actions, and their effects on the schedule.
2. The effect of changes on schedules of other work.
1.04 Modifications to Time of Completion in the Approved Schedule
A. The date of beginning and the times for completion of the work are essential conditions of the Contract
Documents and the work embraced shall be commenced on a date specified in the Notice to Proceed.
The Contractor will proceed with the work at such rate of progress to ensure full completion within the
contract time. It is expressly understood and agreed, by and between the Contractor and the Owner
that the contract time for the completion of the work described herein is a reasonable time, taking into
consideration the climatic and other factors prevailing in the locality of the work.
Every effort shall be made by the Contractor to complete the project within the "Contract Time" shown
in the proposal. The "Contract Time" anticipates a “Normal” weather and climate condition in and
around the vicinity of the Project site during the times of year that the construction will be carried out.
Extensions of time based upon weather conditions shall be granted only if the Contractor demonstrates
clearly that such conditions were "unusually severe," would not have been reasonably anticipated, and
that such conditions adversely affected the Contractor’s work and thus required additional time to
complete the work.
B. The following specifies the procedure for the determination of time extensions for unusually severe
weather. The listing below defines the anticipated number of calendar days lost to adverse weather for
each month and is based upon National Oceanic and Atmospheric Administration (NOAA) or similar
data for the geographic location of the project.
Monthly Anticipated Calendar Days Lost to Adverse Weather Conditions

Park Planning & Development Division Page 3 of 4
JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
(7) (4) (4) (4) (6) (3) (4) (2) (3) (3) (2) (5)
The above schedule of anticipated adverse weather will constitute the base line for monthly (or portion
thereof) weather time evaluations. Upon acknowledgment of the Notice to Proceed and continuing
throughout the contract on a monthly basis, actual adverse weather days and the impact of adverse
weather days that delay the work will be recorded on a day-to-day basis. It is assumed that the work
will be carried out Mondays through Fridays (holidays excluded) unless an approved construction
schedule or written authorization from the Owner indicates otherwise. The number of days of delayed
work due to adverse weather or the impact thereof will then be compared to the monthly adverse
weather schedule above.
An actual adverse weather day must prevent work for 50 percent or more of the Contractor’s workday,
delay work critical to the timely completion of the project, and be documented by the Contractor. The
City Representative observing the construction shall determine on a daily basis whether or not work
can proceed or if work is delayed due to adverse weather or the effects thereof. The Contractor shall
notify the Construction Coordinator in writing of any disagreement as to whether or not work can
proceed on a given date, within 2 calendar days of that date. The Owner will use the above written
notification in determining the number of working days for which work was delayed during each
month.
C. At the end of each month, if the number of working days for which work was delayed due to adverse
weather exceeds that shown in the above schedule, a Change Order will be executed which increases
the Contract Time. The number of workdays delayed due to adverse weather or the impact thereof will
then be converted to Calendar Days based on the contract completion day and date. This conversion
assumes a 5-day work week, Mondays through Fridays, holidays excepted; should the Contractor have
authorization to work weekends and/or holidays, then the method of conversion of workdays to
calendar days would take this into consideration. The contract time period will then be increased by the
number of calendar days calculated above and a new contract completion day and date will be set.
D. The Contractor’s schedule must reflect the above-anticipated adverse weather delays on all weather-
dependent activities.
E. While extensions of time shall be granted for "unusually severe" weather or climate conditions, the
Owner shall make no monetary compensation for any costs to the Contractor arising out of such delays.
The Contractor shall comply with the portions of the Contract Documents relating to his project
schedule and amendments thereto which result from the "unusually severe" weather condition.
F. Breakdowns in equipment or lack of performance by the Contractor will not be considered justification
for an extension of time. Liquidated damages will be assessed as delineated elsewhere.
G. The Contractor shall not be charged with liquidated damages or any excess cost when the delay in
completion of the work is due to the following, and the Contractor has promptly given written notice of
such delay to the Owner or Engineer.
1. To any preference, priority, or allocation order duly issued by the Owner.
2. To unforeseeable causes beyond the control and without the fault or negligence of the Contractor,
including but not restricted to, acts of God, or of the public enemy, acts of the Owner, acts of
another Contractor in the performance of a contract with the Owner, fires, floods, epidemics,
quarantine restrictions, strikes, freight embargoes, and abnormal and unforeseeable weather as
provided above; and
3. To any delays of Subcontractors occasioned by any of the causes specified in paragraphs 1 and 2,
above.
1.05 City's Responsibility
A. City's review is only for the purpose of checking conformity with the Contract Documents and

PART 1 - GENERAL
Description of Work
A. The Contractor shall provide all labor, materials, and equipment necessary to perform the work
items called for on the bid schedule.
B. The Contractor shall perform tree protection regardless of the type, nature, or condition of trees
encountered, as specified or required in order to accomplish the construction.
PART 2 - MATERIALS
2.01 Temporary Fencing
A. Orange construction fencing, five feet or greater in height as required to fulfill the intent of this
section.
B. Fencing anchors for small trees shall be T posts. Anchors for fencing within the drip line of large
trees shall be dual-socket portable concrete pier blocks sufficient to secure the fence in a vertical
position for the construction period.
PART 3 - EXECUTION
3.01 General
A. Prior to and during construction, barriers shall be erected around all protected existing trees.
Barriers shall be orange construction fencing located no closer than six (6) feet to the surface of
the trunk or one-half (½) of the drip line radius, whichever is greater. Posts shall be anchored in
movable concrete blocks so as not to require excavation within the tree’s drip line. There shall be
no storage or movement of equipment, material, debris, or fill within the fenced tree protection
zone. The drip line is defined as the area on the ground covered by the spread of branches.
B. There shall be no cleaning of equipment or material or the storage and disposal of waste material
such as paints, oils, solvents, asphalt, concrete, motor oil or any other material harmful to the life
of a tree within the drip line of any protected tree or group of trees.
C. No attachment, wires, signs, or permits may be fastened to any protected tree.
D. Large areas containing clumps, groves, or copses of protected trees which are naturally separated
from construction or land clearing areas, road rights-of-way and utility easements may be
“ribboned off,” rather than erecting protective fencing around each tree as required above. This
may be accomplished by placing metal t-post stakes a maximum of thirty (30) feet apart and tying
ribbon or rope from stake-to-stake along the outside perimeters of such areas being cleared.
E. The temporary fencing shall be removed by the Contractor only after all heavy equipment has
been permanently withdrawn from the site.
3.02 Excavation
A. Install shoring or other protective support systems to minimize sloping or benching of
excavations.
City of Fort Collins Section 02122 - Tree Protection
Park Planning & Development Division Page 2 of 2
B. Do not excavate within the tree drip line, unless otherwise indicated. Where excavation for new
construction is required within tree drip lines, hand excavate to minimize damage to root systems.
Use narrow-tine spading forks and comb soil to expose roots.
C. Relocate roots in backfill areas wherever possible. If encountering large, main lateral roots,
expose beyond excavation limits as required to bend and relocate without breaking. If
encountered immediately adjacent to location of new construction and relocation is not practical,
cut roots approximately 3 inches back from new construction.
D. After excavation outside the drip line of trees, any severed roots should be cut again smoothly
with flush cuts.
E. Do not allow exposed roots to dry out before placing permanent backfill. Provide temporary earth
cover or pack with compost and wrap with burlap. Water and maintain in a moist condition and
temporarily support and protect roots from damage until they are permanently relocated and
covered with earth.
F. Root Pruning: Do not cut main lateral roots or tap roots; cut only smaller roots that interfere with
installation of new work. Cut roots with sharp pruning instruments; do not break or chop. Roots
1 inch and larger shall be painted with two coats of Tree Seal or approved equal.
G. Trenching should be done outside the drip line of trees. The installation of utilities, irrigation
lines, or any underground fixture requiring excavation deeper than six inches shall be
accomplished by boring under the root system of protected existing trees at a minimum depth of
24 inches. The auger distance is established from the face of the tree (outer bark) and is scaled
from tree diameter at breast height as described in the chart below.

On-site cohesive soils or imported soils should be placed and compacted in thin, horizontal lifts,
not to exceed 8 inches in thickness (measured prior to compaction), using equipment and
procedures that will produce recommended moisture contents and densities throughout the lift and
embankment height. On-site or imported cohesive soils should be compacted within a moisture
content range of optimum to 3% above optimum moisture content and compacted to 95% of the
Maximum Standard Proctor Density (ASTM D698).
When embankment is to be placed and compacted on hillsides, or when new embankment is to be
compacted against existing embankments, or when embankment is built 1/2 width at a time, the
slopes that are steeper than 4:1 when measured longitudinally or at right angles to the adjacent
ground shall be continuously benched over those areas where it is required as the work is brought
up in layers. Benching shall be well keyed and where practical a minimum of 8 feet. Each
horizontal cut shall begin at the intersection of the original ground and the vertical sides of the
Spring Canyon Community Park SECTION 02301 – EARTHWORK
Page 4 of 7
previous cuts. Material thus cut out shall be recompacted along with the new embankment
material at the CONTRACTOR’s expense.
The ground surface underlying all fills shall be carefully prepared by removing all organic matter,
scarification to a depth of 8 inches and recompacting to 95% of the Maximum Standard Proctor
Density (ASTM D698) at optimum moisture content + or - 2% prior to fill placement.
Embankment material shall be placed in horizontal layers not exceeding 8 inches (loose
measurement) and shall be compacted to 95% of the Maximum Standard Proctor Density (ASTM
D698) at optimum moisture content + or - 2%. Effective spreading equipment shall be used on
each lift to obtain uniform thickness prior to compacting. As the compaction of each layer
progresses, continuous leveling and manipulating will be required to assure uniform density.
A moisture density determination shall be made for each soil type encountered. Unless directed
by the geotechnical engineer, the standard Proctor maximum dry density (ASTM D 698) shall
apply.
For embankments which serve as berms, the downstream portion shall be "keyed" into the
subsurface soils a minimum of 3 feet to enhance the stability of the slope.
Materials which are removed from excavations beneath the water table may be over the
acceptable moisture content range and will require that they be dried out prior to reusing them.
Cross hauling or other action as appropriate will be ordered when necessary to insure that the best
available material is placed in critical areas of embankments, including the top 2 feet of all
embankments. No additional payment will be made for cross hauling ordered by the ENGINEER.
Frozen materials shall not be used in construction of embankments and embankments shall not be
constructed on frozen materials.
During the construction of the channels, the channel bottom shall be maintained in such condition
that it will be well drained at all times.
Excavation or Embankment (Fill), and Structural Backfill work either completed or in a stage of
completion that is either eroded or washed away or becomes unstable due to either rains, snow,
snow melt, channel flows or lack of proper water control shall be either removed and replaced,
recompacted or reshaped as directed by the ENGINEER and in accordance with the Drawings and
Specifications at the CONTRACTOR’s sole expense. Removed unsuitable materials shall be
hauled away and disposed of at the CONTRACTOR’s expense. Placing of replacement materials
for removed unsuitable materials shall be purchased, placed and compacted at the
CONTRACTOR’ expense.
B. Proofrolling with a heavy rubber tired roller will be required, if designated on the Drawings or
when ordered by the ENGINEER. Proof rolling shall be done after specified compaction has
been obtained. Areas found to be weak and those areas which failed shall be ripped, scarified,
wetted if necessary, and recompacted to the requirements for density and moisture at the
CONTRACTOR’s expense.
Proof rolling shall be done with equipment and in a manner acceptable to the ENGINEER. Proof
rolling as shown on the Drawings or as ordered by the ENGINEER shall not be measured and
paid for separately, but shall be included in the unit prices bid for the work.
3.05 Excavation and Backfill for Structures
A. Poor foundation material for any of the work shall be removed, by the CONTRACTOR, as
directed by the ENGINEER. The CONTRACTOR will be compensated for removal and
replacement of such materials in accordance with Muck Excavation.
The CONTRACTOR is cautioned that construction equipment may cause the natural soils to
pump or deform while performing excavation work inside and on footings, structural floor slabs,
or other structure foundation areas.
Spring Canyon Community Park SECTION 02301 – EARTHWORK
Page 5 of 7
Foundation materials which are: a) saturated by either surface or subsurface flows due to the lack
of adequate water control or dewatering work by the CONTRACTOR; b) frozen for any reason;
or, c) that are disturbed by the CONTRACTOR’s work or caused to become unacceptable for
foundation material purposes by means of the CONTRACTOR’s equipment, manpower, or
methods of work shall be removed and replaced by the CONTRACTOR at his expense.
Dewatering should not be conducted by pumping from inside footing, structural floor slab, or
other structure foundation limits. This may decrease the supporting capacity of the soils.
Care should be taken when excavating the foundations to avoid disturbing the supporting
materials. Excavation by either hand or careful backhoe soil removal, may be required in
excavating the last few inches of material to obtain the subgrade of any item of the concrete work.
Any over-excavated subgrades that are due to the CONTRACTOR’s actions, shall be brought
back to subgrade elevations by the CONTRACTOR and at his expense in the following manner:
1. For over-excavations of 2 inches or less, either: Backfill and compact with an approved
granular materials; backfill with 1/2 inch crushed rock; or fill within concrete at the time of
the appurtenant structure concrete pour.
2. For over-excavations greater than 2 inches, backfill and compact with an approved granular
material.
All granular footings, structural floor slabs, or other structure areas shall be compacted with a
vibratory plate compactor prior to placement of concrete, reinforcing, or bedding materials.
B. Backfill, and fill within 3 feet adjacent to all structures and for full height of the walls, shall be
selected non-swelling material. It shall be granular, well graded, and free from stones larger than
2 inches. Material may be job excavated, but selectivity will be required as determined by the
ENGINEER. Refer to the Plans for job specific requirements. Stockpiled material, other than
topsoil from the excavation shall be used for backfilling unless an impervious structural backfill is
specified. The backfill material shall consist of either clean on-site granular materials free of
stones larger than 2 inches in diameter with no more than 20% passing the No. 200 sieve, or
equivalent imported materials. All backfill around the structures shall be consolidated by
mechanical tamping. The material shall be placed in 6-inch loose lifts within a range of 2% above
to 2% below the optimum moisture content and compacted to 95% of Maximum Standard Proctor
Density (ASTM D698) for sand soils, or to 75% relative density as determined by the relative
density of cohesionless soils test, ASTM D4253.
When specified on the Drawings or as required by the ENGINEER, Class I structural backfill
shall meet the following gradation requirements:
Sieve Size
% by Weight Passing
Square Mesh Sieves
2-Inch 100
No. 4 30 – 100

PART 2 PRODUCTS
2.01 MATERIALS
A. Embankment material may consist of approved material acquired from excavations or material
hauled from outside the project limits. Suitable material identified on-site shall be used first for
embankments and backfill. Excess excavated native soils which are not used as embankment or
backfill shall become the property of the CONTRACTOR and shall be disposed of off-site by the
CONTRACTOR, in a location acceptable to the ENGINEER.
B. Muck excavation encountered in all areas other then within the lakes shall also include the
replacement of excavated muck with uniformly graded rock, riprap, on-site or imported soils, or
other material whichever is most suitable for the specific situation encountered. The ENGINEER
will determine which type of aggregate or other material which shall be used after observing the
specific site conditions.
PART 3 EXECUTION
3.01 GENERAL EXCAVATION/EMBANKMENT
A. General: The excavation and embankment for the project work shall be finished to reasonably
smooth and uniform surfaces. Variation from the subgrade plane shall not be more than .08 feet in
soil or more than .08 feet above or .50 below in rock. Materials shall not be wasted without
permission of the ENGINEER. Excavation operations shall be conducted so that material outside of
the limits of slopes will not be disturbed.
B. When the CONTRACTOR’s excavating operations encounter remains of pre-historic people’s
dwelling sites or artifacts of historical or archaeological significance, the operations, shall be
temporarily discontinued. The ENGINEER will contact archaeological authorities to determine the
disposition thereof. When directed, the CONTRACTOR shall excavate the site in such a manner as
to preserve the artifacts encountered and shall remove them for delivery to the custody of the proper
state authorities. Such excavation will be considered and paid for as extra work.
C. Excavation:
1. Unclassified: All excess suitable material excavated from the project site and not used for
embankment shall be removed from the project site and become the property of the
CONTRACTOR. Where material encountered within the limit of the work is considered
unsuitable for embankment (fills) on any portion of this project work, such material shall
be excavated as directed by the ENGINEER and replaced with suitable fill material. All
unsuitable excavated material from excavation consisting of any type of debris (surface or
buried), excavated rock, bedrock or rocks larger than 6 inches in diameter and boulders
shall be hauled from the project site and disposed of. Debris is defined as “anything that is
not earth which exists at the job site”.
2. Muck: Where excavation to the finished grade section results in a subgrade or slopes of
unsuitable soil, the ENGINEER may require the CONTRACTOR to remove the unsuitable
materials and backfill to the finished graded section with approved material. Disposal of
the material shall be at the CONTRACTOR’s expense.
Good surface drainage shall be provided around all permanent cuts to direct surface runoff
away from the cut face.
Rock: Unless otherwise specified, rock shall be excavated to a minimum depth of 0.5 feet
below subgrade within the limits of the channel area, and the excavation shall be backfilled
with material shown on the Drawings or as designated by the ENGINEER. Disposal of
material and replacement with suitable approved material shall be at the CONTRACTOR’s
expense.

D. Embankment Construction: Embankment construction shall consist of constructing all fill areas,
including preparation of the areas upon which they are to be placed, and the placing and compacting
of embankment material in holes, pits and other depressions within the project area. Only approved
materials shall be used in the construction of embankments and backfills.
Approved materials shall consist of clean on-site cohesive soils or approved imported soils. On-site
cohesive soils are suitable for use as compacted fill provided the following recommendations are
met:
Excavation and Embankment will only be paid when a significant change in grade is required, as
determined by the ENGINEER. Minor cuts and fills will be considered incidental to the work, and
will not be paid for separately under this section.

On-site cohesive soils or imported soils should be placed and compacted in horizontal lifts, using
equipment and procedures that will produce recommended moisture contents and densities
throughout the lift and embankment height. On-site or imported cohesive soils should be compacted
within a moisture content range of 2% below, to 2% above optimum moisture content and
compacted to 95% of the Maximum Standard Proctor Density (ASTM D698).
When embankment is to be placed and compacted on hillsides, or when new embankment is to be
compacted against existing embankments, or when embankment is built 1/2 width at a time, the
slopes that are steeper than 4:1 when measured longitudinally or at right angles to the adjacent
ground shall be continuously benched over those areas where it is required as the work is brought up
in layers. Benching shall be well keyed and where practical a minimum of 8 feet. Each horizontal
cut shall begin at the intersection of the original ground and the vertical sides of the previous cuts.
Material thus cut out shall be recompacted along with the new embankment material at the
CONTRACTOR’s expense.
The ground surface underlying all fills shall be carefully prepared by removing all organic matter,
scarification to a depth of 8 inches and recompacting to 95% of the Maximum Standard Proctor
Density (ASTM D698) at optimum moisture content + or - 2% prior to fill placement.
Embankment material shall be placed in horizontal layers not exceeding 8 inches (loose
measurement) and shall be compacted to 95% of the Maximum Standard Proctor Density (ASTM
D698) at optimum moisture content + or - 2%. Effective spreading equipment shall be used on each
lift to obtain uniform thickness prior to compacting. As the compaction of each layer progresses,
continuous leveling and manipulating will be required to assure uniform density.
For embankments which serve as berms, the downstream portion shall be “keyed” into the
subsurface soils a minimum of 3 feet to enhance the stability of the slope.
Materials which are removed from excavations beneath the water table may be over the optimum
moisture content and will require that they be dried out prior to reusing them.

Park Planning & Development Division Page 4 of 4
Cross hauling or other action as appropriate will be ordered when necessary to insure that the best
available material is placed in critical areas of embankments, including the top 2 feet of all
embankments. No additional payment will be made for cross hauling ordered by the ENGINEER.
Frozen materials shall not be used in construction of embankments.
During the construction of the channels, the channel bottom shall be maintained in such condition
that it will be well drained at all times.
Excavation or Embankment (Fill), and Structural Backfill work either completed or in a stage of
completion that is either eroded or washed away or becomes unstable due to either rains, snow,
snow melt, channel flows or lack of proper water control shall be either removed and replaced,
recompacted or reshaped as directed by the ENGINEER and in accordance with the Drawings and
Specifications at the CONTRACTOR’s sole expense. Removed unsuitable materials shall be hauled
away and disposed of at the CONTRACTOR’s expense. Placing of replacement materials for
removed unsuitable materials shall be purchased, placed and compacted at the CONTRACTOR’
expense.
E. Proof rolling with a heavy rubber tired roller will be required, if designated on the Drawings or
when ordered by the ENGINEER. Proof rolling shall be done after specified compaction has been
obtained. Areas found to be weak and those areas which failed shall be ripped, scarified, wetted if
necessary, and recompacted to the requirements for density and moisture at the CONTRACTOR’s
expense.
Proof rolling shall be done with equipment and in a manner acceptable to the ENGINEER. Proof
rolling as shown on the Drawings or as ordered by the ENGINEER shall not be measured and paid
for separately, but shall be included in the unit prices bid for the work.

B. Acceptance: Beginning of installation means acceptance of existing conditions.
3.02 Preparation
A. Preparation of Surfaces
1. Clean surfaces in accordance with manufacturer s recommendations.
2. Mask edges, if required to protect adjoining surfaces and produce a straight finish
line.
3. Clean joint surfaces immediately before installation of sealant. Remove dirt, insecure
coatings, moisture and other substances which would interfere with bond of sealant.
4. Do not proceed with installation of sealant over joint surfaces which have been painted,
lacquered, waterproofed or treatead with water repellent or other treatment of
coating. Remove coating or treatment joint surfaces before installing sealant.
5. Each concrete masonry joint surfaces to remove excess alkalinity unless sealant
manufacturer s printed instruction indicates that alkalinity does not interfere with
sealant bond and performance. Etch with 5% solution of muriatic acid, neutralize with
diluted ammonia solution, rinse thoroughly with water and allow to dry before
sealant installation.
B. Priming: If required, prime surfaces which are to be caulked with manufacturer s recommended or
standard primer, after the surfaces have been prepared as specified. Before use, check primers for
discoloration and dirt pick-up on adjacent surfaces. If staining occurs, after exposure, take
adequate measures to prevent the primer from being applied over the face of adjacent porous
materials by masking or other suitable measures.
C. Joint Backing:

to ensure that sealants will perform properly.
3.03 Application
A. Exterior Metal Sills: Set in full bed of polyurethane sealant.
B. Thresholds: Set in full bed of latex acrylic sealant.
C. Caulk Joints:
1. Apply sealants in continuous beads without open joints, voids, or air pockets, using a
ratchet hand gun or mechanical powered gun.
2. Confine sealants to joint areas with masking tapes or other precautions. Apply
compounds in concealed compression joints accurately so that excess compound will not
extrude from joints.
City of Fort Collins Section 07900 – Joint Sealers
Park Planning & Development Division Page 4 of 5
3. Remove excess compound or sealant promptly as work progressess, and clean adjoining
surfaces.
4. In rough surfaces or joints of uneven widths, install sealant, well back into joint. Recess
equal to width of joint, or 3/8" minimum at masonry.
5. Use anti-tack agent where necessary to protect freshly applied sealant from public traffic
and dirt.
6. Slightly recessed joints as to facilitate a painter s line. Handtool and finish joints
throughout construction.
7. Comply with manufacturer s printed instructions and specifications.
D. Concrete Paving Expansion Joints: Cut expansion joint filler down to allow joint depth equal to
75% of joint width, but neither more than 0.625" deep nor less than 0.375" deep. Seal over
expansion joint filler with poured sealant.
E. Workmanship: Employ only proven installation techniques, which will ensure that sealants will be
deposited in uniform, continuous ribbons without gaps or air pockets, with complete wetting of
the joint bond surfaces equally on opposite sides. Except as otherwise indicated, fill sealant rabbet
to a slightly concave surface, slightly below adjoining surfaces. Where horizontal joints are
between a horizontal surface and a vertical surface, fill joint to form a slight cove, so that joint will
not trap moisture and dirt.
F. Joint Sizes: Install sealants to depths as indicated or, as recommended by the sealant manufacturer
but within the following general limitations:
1. For normal moving joints sealed with elastomeric sealants but not subject to traffic, fill
joints to a depth equal to 50% of joint width, but not more than 1/2" deep or less than
1/4" deep.
2. For joints sealed with non-elastomeric sealants and caulking compounds, fill joints to a
depth in the range of 75% to 125% of joint width.
G. Spillage:
1. Do not allow sealants or compounds to overflow or spill onto adjoining surfaces, or to
migrate into the voids of adjoining surfaces. Use masking tape or other precautionary
devices to prevent staining of adjoining surfaces, by either the primer/sealer or the
sealant.
2. Remove excess and spillage of compounds promptly as the work progresses. Clean the
adjoining surfaces by whatever means may be necessary to eliminate evidence of
spillage. Do not damage the adjoining surfaces or finishes.
3.04 FIELD QUALITY CONTROL
