DIVISION 1
SECTION 01160 — SITE CONDITIONS
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 Owner assumes no responsibility for
representations made by its officers or agents during or prior to the execution of this
Contract, unless (1) such representations are expressly stated in 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
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 responsibility for the
completeness or interpretation of such supplementary information.
A. Differing Subsurface Conditions:
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 generally recognized as inherent in the
character of work covered in these Contract Documents, the Contractor shall
promptly, and before such conditions are disturbed, notify the Owner in writing of
such changed conditions.
2. The Engineer will investigate such conditions promptly and following this
investigation, the Contractor shall proceed with the work, unless otherwise
instructed by the Engineer. If the Engineer finds that such conditions do so
materially differ and cause an increase or decrease in the cost of or in the time
required for performing the work, the Engineer will recommend to the Owner the
amount of adjustment in cost and time he considers reasonable. The Owner will
make the final decision on Change Orders to the Contract regarding adjustments
in cost or time for completion.
B. Underground Utilities:
Known utilities and structures adjacent to or encountered in the work are shown
on the Drawings. The locations shown are taken from existing records and the
best information available from existing utility plans, however, it is expected that
there may be some discrepancies and omissions in the locations and quantities
of utilities and structures shown. Those shown are for the convenience of the
Contractor only, and no responsibility is assumed by either the Owner or the
Engineer for their accuracy or completeness.
PART 3 - CONTRACTOR'S RESPONSIBILITY FOR UTILITY PROPERTIES AND SERVICE
3.01 General
A. Where the Contractor's operations could cause damage or inconvenience to railway,
telegraph, telephone, television, oil, gas, electricity, water, sewer, or irrigation
systems, the operations shall be suspended until arrangements necessary for the
protection of these utilities and services have been made by the Contractor.
B. Notify utility offices which are affected by the construction operation at least 48 hours
in advance. Under no circumstances expose any utility without first obtaining
permission from the appropriate agency. Once permission has been granted, locate,
expose, and provide temporary support for existing underground utilities.
C. The Contractor shall protect utility poles from damage. If interference of power
poles, telephone poles, guy wires, or anchors are encountered, notify the Owner's
Representative and the appropriate utility company at least 48 hours in advance of
construction operations to permit the necessary arrangements for protection or
relocation of the interfering structure.
D. The Contractor shall be solely and directly responsible to the Owner and operators of
such properties for damage, injury, expense, loss, inconvenience, delay, suits,
actions, or claims of any character brought because of injuries or damage which may
result from the construction operations under this Contract.
E. Neither the Owner nor its officers or agents shall be responsible to the Contractor for
damages as a result of the Contractor's failure to protect utilities encountered in the
work.
F. If the Contractor while performing the Contract discovers utility facilities not identified
in the Drawings or Specifications, he shall immediately notify the Owners and the
utility in writing.
G. In the event of interruption to domestic water, sewer, storm drain, or other utility
services as a result of accidental breakage due to construction operations, promptly
notify the proper authority. Cooperate with said authority in the restoration of service
s
as promptly as possible and bear all costs of repair. In no case shall interruption of
water or utility service be allowed to exist outside working hours unless prior
approval is granted.
H. The Contractor shall replace, at his own expense, existing utilities or structures
removed or damaged during construction, unless otherwise provided for in these
Contract Documents or ordered by the Engineer.
3.02 Interfering Structures
A. Take necessary precautions to prevent damage to existing structures whether on the
surface, aboveground, or underground. An attempt has been made to show major
structures on the Drawings. The completeness and accuracy cannot be guaranteed,
and it is presented simply as a guide to avoid known possible difficulties.
3.03 Field Relocation
A. During the progress of construction, it is expected that minor relocations of the work
will be necessary. Such relocations shall be made only by direction of the Owner's
Representative. If existing structures are encountered that prevent the construction,
and that are not properly shown on the drawings, notify the Owner's Representative
before continuing with the construction in order that the Owner's Representative may
make such field revision as necessary to avoid conflict with the existing structures. If
the Contractor shall fail to so notify the Owner's Representative when an existing
structure is encountered, and shall proceed with the construction despite the
interference, he shall do so at his own risk.
3.04 Easements
A. Easements and permits will be obtained by the Owner where portions of the work are
located on public or private property. Easements will provide for the use of the
property for construction purposes to the extent indicated on the easements. Copies
of these easements and permits are available upon request to the Owner. It shall be
the Contractor's responsibility to determine the adequacy of the easement obtained
in every case and to abide by requirements and provisions of the easement. The
Contractor shall confine his construction operations to within the easement limits or
make special arrangements with the property owners or appropriate public agency
for the additional area required. Damage to property, either inside or outside the
limits of the easements provided by the Owner, shall be the responsibility of the
Contractor as specified herein. The Contractor shall remove, protect, and replace
fences or other items encountered on public or private property. Before final
payment will be authorized by the Owner's Representative, the Contractor will be
required to furnish the Owner with written releases from property owners or public
agencies where side agreements or special easements have been made by the
Contractor or where the Contractor's operations, for any reason, have not been kept
within the construction right-of-way obtained by the Owner.
B. It is anticipated that the required easements and permission will be obtained before
construction is started. However, should the procurement of any easement or
permission be delayed, the Contractor shall schedule and perform the work around
these areas until such a time as the easement or permission has been secured.
3.05 Land Monuments
A. The Contractor shall notify the Owner's Representative of existing Federal, State,
Town, County, and private land monuments encountered. Private monuments shall
be preserved, or replaced by a licensed surveyor at the Contractor's expense. When
Government monuments are encountered, the Contractor shall notify the Owner's
Representative at least two (2) weeks in advance of the proposed construction in
order that the Owner's Representative will have ample opportunity to notify the
proper authority and reference these monuments for later replacement.

SECTION 01310 - CONSTRUCTION SCHEDULES
PART 1 - GENERAL
1.01 General
A. It is the intent of the Owner to begin construction on approximately October 1, 2009.
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 November
15, 2009, 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. 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 away 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.
G. 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
14
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 or suspended. Such shutdown will not be
compensated by cost reimbursement or time schedule adjustment.
H. 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

that will reflect work performed in the previous week and the upcoming week.
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
15
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
JAN FEB MAR AP MAY JUN JUL AUG SEP OC NOV DE
R T C
(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 excepted) 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
16
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 assisting Contractor in coordinating the Work with the needs of the
Project.
B. It is not to be construed as relieving Contractor from any responsibility to determine
the means, methods, techniques, sequences, and procedures of construction as
provided in the General Conditions.

ascertain that the method of blasting will be in accordance with state and local
ordinances. Any blasting shall be done only under the direct supervision of a
certified blaster.
3.05 Sheathing and Bracing
A. Where it is necessary to protect nearby structures and pavements, or when the
trench must be confined to allow for traffic flow, tight sheathing will be required.
The Contractor to call the Construction Coordinator's attention to any unforeseen
condition that requires the use of sheathing. Sheathing must be driven unless
soil conditions allow the sets to be placed after excavating. If placed after
excavating, the voids between the trench wall and sheathing must be
immediately filled with sand.
B. Removal of sheathing must not take place until the trench is backfilled. Flooding
or jetting the trench shall be done after the sheathing is removed.
C. The Construction Coordinator may approve, in writing, some or all of the
sheathed sets to remain in place. Sheathing ordered left in place shall have the
upper portion within 2 feet of a street surface cut off and removed.
D. Spot braces, individual shorings spaced at various intervals along trench,
portable trench boxes or sliding shields will be considered incidental to the cost
of the pipe laying.
3.06 Wet Trench Conditions
A. The Contractor shall attempt to dispose of all groundwater or surface drainage
seeping in the trench by employing ordinary dewatering techniques such as the
58
use of sump pumps, dikes, etc. Allowing water to flow into the pipe being laid
will not be permitted except in the case of a storm sewer where the joints have
set. Water entering the installed pipe must flow through the pipe or be pumped
out. The installed pipe shall not be used as a reservoir. A temporary stopper or
plug must be installed on the upper end of each pipe being laid if there is danger
of sand or debris being washed into the pipe. Do not place water so that it
ponds on roadway subgrade or adjacent private property..
B. Contractor shall follow provisions of Section 02140 Water Control, the approved
Water Control Plan, and the Groundwater Discharge Permit.
C. If the existing soil in the trench bottom is judged to be unsuitable by the
Construction Coordinator after dewatering measures have been taken, a
minimum of the top 6-inches of the subgrade shall be removed and replaced
with stabilization material.
3.07 Dewatering
A. Contractor shall be responsible for maintaining a dry trench by ordinary
dewatering techniques, well points, or other measures as approved in the Water
Control Plan or by the Construction Coordinator during the course of work.
B. If wells are utilized for dewatering, the wells shall be drilled, maintained, and
abandoned in accordance with the requirements of the State of Colorado, Office
of the State Engineer.
3.08 Granular Base to Replace Poor Subsoil
A. At any time material such as muck, sawdust, bark, or other material is
encountered which would not form a suitable and permanent base, the
Construction Coordinator shall be notified to decide if it should be removed and
replaced with suitable granular bedding or stabilization material. The sand or
gravel base replacement is to be compacted in 6-inch layers up to the bottom of
the normal trench section.
3.09 Granular Bedding
A. Bedding material shall be placed from the trench bottom to the pipe spring line in
accordance with the Drawings or as required by pipe material specifications.
3.10 Backfilling with Existing Material

clay or other unsuitable material if approved by the Construction Coordinator.
Trench backfill over the initial backfill zone may be previously excavated soil
except as determined by the Construction Coordinator to be unsuitable.
C. The initial backfill material over the pipe up to a minimum depth of one foot above
the pipe shall be filled in by hand and well compacted over and around the pipe
with hand tampers or mechanical means to the proper density. Special care
shall be taken in placing and tamping the initial backfill material so the alignment
and grade of the pipe will not be disturbed nor the pipe damaged.
59
D. When backfilling in frozen material, the Contractor shall cover the pipe and tamp
the backfill around the pipe using only loose thawed material. No frozen material
shall be placed in the trench. All frozen material shall be kept from around
manholes and other structures.
3.11 Granular Backfill
A. Granular backfill shall be provided by the Contractor and placed in the trench
when the excavated material is unsuitable for backfill or when ordered by the
Construction Coordinator. Bank run gravel may be used provided the initial
backfill zone (one foot above pipe) has been filled with acceptable granular
bedding material.
3.12 Trench Compaction
A. The pipe trench shall be backfilled to the limits as shown on the Contract
Drawings. The backfill in all areas shall be moisture treated to within 2 percent
of optimum moisture content (sand soils) or between optimum and 3 percent
over optimum moisture content (clay soils), processed to a uniform consistency,
placed in 8 inch maximum loose lifts, and compacted by vibrating, tamping, or a
combination thereof to 75% relative density for sand material as determined by
the relative density of cohesionless soils test, ASTM D4253, or to 95% of the
Maximum Standard Proctor Density for cohesive soils as determined by ASTM
D698. Where cement sand is utilized, compaction may be achieved using at
least 5 passes of a heavy, walk behind or self-propelled, vibratory mechanical
compactor. Prior to compaction, sand soils shall be brought to within 2 percent
of the optimum moisture content, and clay soils shall be processed to between
optimum and 3 percent above optimum moisture content for soil compacted
according to ASTM D698.
All backfill shall be brought up to equal height along each side of the pipe in such
a manner as to avoid displacement. Backfill material shall be distributed in 6-
inch maximum lifts over the full width of the trench. Wet, soft or frozen material,
asphalt chunks, or other deleterious substances shall not be used for backfill. If
the excavated material is not suitable for backfill, as determined by the
ENGINEER, suitable material shall be hauled in and utilized and the rejected
material hauled away and disposed of.
Backfilling shall be conducted at all times in a manner to prevent damage to the
pipe or its coating and shall be kept as close to the pipe laying operation as
practical.
Backfilling procedures shall conform to the additional requirements, if any, of
appropriate agencies or private right-of-way agreements.
3.13 Restoration
A. Unsurfaced Areas:
All surface cuts shall be, as a minimum, restored to a condition equal to that prior
to construction.
B. Surfaced Areas:
All surface cuts shall be, as a minimum, restored to a condition equal to that prior
to construction. All gravel or paved streets shall be restored in accordance with
the regulations and requirements of the agency having control or jurisdiction
over the street, roadway, or right-of-way.
60
C. Grassed or Landscaped Areas:
In landscaped or agricultural areas, topsoil, to a depth of 12 inches, shall be
removed from the area of general disturbance and stockpiled. After installation
of all pipelines, appurtenances and structures and completion of all backfill and
compaction, the stockpiled topsoil shall be redistributed evenly over all disturbed
areas. Care should be taken to conform to the original ground contour or final
grading plans.
3.14 Disposal of Surplus or Undesirable Material
A. Surplus material shall include all excavation that is more than the amount needed
for backfilling or is undesirable for backfilling.
B. The Contractor shall find his own disposal sites, remove and load excess
material, haul, and dispose of material. Such material shall become property of
the Contractor. Measurement and payment will not be made separately but will
be incidental to other Bid Items.
