SECTION 01570
TREE PROTECTION
A. Tree Barriers:
All trees which will be preserved, but are within the limits of construction, must be protected from all
damage associated with construction. A sturdy, physical barrier (fluorescent orange in color) must be fixed
in place around each tree for the duration of construction. This barrier will be placed no closer than six (6)
feet from the trunk, or one-half of the drip line, whichever is greater. The barrier itself must be fixed so it
cannot be moved easily, but the material can be flexible, such as orange safety fence attached to metal T-
posts driven into the ground, but must act as an effective deterrent to deliberate or accidental damage of
each tree. The Project Engineer or Manager must approve actual materials and location of barrier.
The movement or storage of equipment, material, debris, or fill within these required protective barriers is
completely prohibited.
In situations where the construction will come closer to a tree than six (6) feet, the orange barrier must still
be erected. However, additional padding must be placed around the trunk of each tree starting at ground
level and proceeding up the trunk to a height of six or seven feet. Padding should be a minimum eight (8)
inches thick, and made of a material strong enough to protect the bark from accidental impacts with hand
tools or power equipment.
B. Accidental Poisoning:
During the construction, the Contractor shall not cause, or permit the cleaning of equipment or material
within the root zone of any tree. The Contractor shall not store or dispose of waste material including, but
not limited to; paints, solvents, asphalt, concrete, mortar, or any other material harmful to the life of a tree,
within the root zone of each tree, or group of trees.
C. Root Pruning Specifications:
When the cutting of tree roots is necessary, each final cut must be made as cleanly as possible for all roots
over three (3) inches in diameter using the following method:
1. The line of excavation will be drawn out and appropriate excavation equipment used to clear the area
at least six inches in front of the actual finished excavation line. Roots can then be cut using tools such
as axes, stump grinders, or trenchers.
2. Each root over three (3) inches in diameter will then be cut cleanly back to the excavation line using a
stump grinder operated by an experienced licensed arborist. A sharp hand or bow saw is acceptable for
roots under three (3) inches in diameter. Axes and trenchers do not cut roots cleanly and will not be
used for final root cuts.
D. Contractor shall coordinate with the Owners’ Field Representative prior to and during the
installation of tree protection and root pruning activities. Owners’ Field Representative, at his/her
opinion, will contact the City Forester and/or City Arborist for advice and approval of the tree
protection measures taken by the Contractor and also the City’s advice and approval during the root
pruning activities.
E. No damaging attachments, wires, signs, permits or other objects may be fastened by any means to
any tree preserved on this project.
F. Violation of Specifications and Penalties for Damaging Trees:
Any violation of these specifications will lead to penalties based on the type of violation and/or the
Ziegler Road / Kechter Road Roundabout Project
P:\Street Oversizing\Ziegler Road Kechter Road Roundabout\Bid Docs\Construction Specs\General Reqs
General Reqs. - 18
resulting damages, and may be grounds for the termination of this contract.
The penalties will be assessed based on the amount of damage done and the total value of that tree, or
group of trees, prior to the damage. The minimum penalty will be $100.00. Penalties for any damage will
be based on the total value of the tree as determined by the City Forestry Division staff and the severity of
the damage as a proportion of the total value of that tree. This could include up to the full value of the tree.
As an example, there are two American Elm trees to be preserved on another project. They are
valued at $7,960 and $6,667 for the south and north trees respectively. The south tree is
approximately 100 inches in circumference, therefore each inch is worth one-hundredth of the
value, or $79.60 per inch. Similarly, the north tree is 91 inches in circumference, making each
inch worth $73.26. To extend this to penalties paid, if one inch of the bark on the south tree is
scuffed, the penalty would be $100 (the minimum allowed); if two inches are damaged, the penalty
would be $159.20 and so on up to 50% of the circumference of the trunk. If 50% or more is
damaged, the full value of the tree will be assessed as a penalty. (This example serves to illustrate
how damages will be assessed).
This method of assessing penalties will be applicable to all trees not marked for removal on the
project, accidental poisoning and improper pruning.

REVISION OF SECTION 102
COST PLUS TIME BIDDING (A + B)
Section 102 of the Standard Specifications is hereby revised for this project as follows:
Add subsection 102.11 as follows:
102.11 Cost Plus Time Bidding (A + B). A special bidding procedure will be used to determine the successful
bidder for this project. This procedure takes into account the price offerings from the bidder and the time the bidder
intends to take to substantially complete the work.
The work is substantially complete when: (1) all work requiring lane or shoulder closures or other traffic
obstructions is complete; (2) traffic is following the lane arrangement shown on the plans for the finished roadway;
(3) all pavement construction, joint sealing, and shoulder embankment is complete; (4) traffic control devices and
pavement markings are in their final positions; (5) all pedestrian sidewalks and decorative crosswalks within the
right-of-way are completed; and (6) all median work (hardscaping, topsoil and fabric) is completed. Work that does
not conform to the Contract will not be accepted as substantially complete. Acceptance of the work as substantially
complete will be determined in accordance with subsection 105.16(b).
(a) Preparation of Proposal. The bidder shall establish the number of calendar days that will be required to
substantially complete the work. The calendar day number shall be included in the bid proposal. This
calendar day number multiplied by the daily cost shall be added to the total amount bid for the work
items. The sum of these two amounts will be used to determine the lowest successful bidder according to
the following formula:
A + B x (the daily cost) = Contractor’s bid for evaluation of the lowest successful bidder
Where:
A = Contractor’s total bid for the work items
B = Number of Calendar days required to substantially complete the work.
Daily cost for this project = $2,072.00
The above formula will be used solely for the purpose of determining the lowest successful bidder and will
have no effect on the actual total bid cost for completing the work.
(b) Early Completion of the Work Incentive. If the Contractor substantially completes the work in less than
the total number of days bid, an incentive will be paid to the Contractor. This incentive (I) will equal the
number of calendar days bid (B) minus the actual number of calendar days required to substantially
complete the work (C) multiplied by the daily cost.
I = (B – C) x (the daily cost)
The maximum incentive is limited to five percent of the Contractor’s total bid for the work items (0.05 x
A).
(c) Late Completion of the Work Disincentive. If the number of calendar days required to substantially
complete the work is in excess of the total number of calendar days bid, a disincentive will be deducted
from payments made to the Contractor. This disincentive (D) will equal the actual number of calendar
days required to substantially complete the work (C) minus the number of calendar days bid (B)
multiplied by the daily cost.
D = (C – B) x (the daily cost)

REVISION OF SECTION 307
FLYASH SUBGRADE STABILIZATION
Section 307 of the Standard Specifications is revised as follows:
This item shall consist of treating the sub-grade, from back of curb to back of curb, adding Class "C" flyash, mixing and
compacting of the mixed material to the required depth and density. This item applies to natural ground or embankment
and shall be constructed as specified herein and in conformity with the typical sections, lines and grades as shown on the
plans or as established by the Engineer.
MATERIALS
A. Flyash - The flyash shall meet ASTM Specification 618, Section 3.2, when sampled and tested in accordance
with Sections 4, 6, and 8 unless otherwise shown on the plans. Flyash shall be Class C designation containing a
minimum of 25 percent CaO.
B. Water - The water used in the stabilized mixture shall be clean, clear, and free of sewage, vegetable matter, oil,
acid, and alkali. Water known to be potable may be used without testing. All other sources shall be tested in
accordance with AASHTO T-26 and approved by the Materials Engineer.
EQUIPMENT
A. The machinery, tools and equipment necessary for proper prosecution of the Work shall be on the project site
and approved by the Engineer prior to the beginning of construction operations. All machinery, tools and
equipment used shall be maintained in a satisfactory and workmanlike manner.
B. Flyash shall be stored and handled in closed weatherproof containers until immediately before distribution on
the road. If storage bins are used, they shall be completely enclosed.
C. If flyash is furnished in trucks, each truck shall have the weight of flyash certified on public scales or the
Contractor shall place a set of standard platform truck scales or hopper scales at a location approved by the
Engineer.
D. All sheep foot compactors shall have all cleaner bars in working condition.
E. At the direction of the on-site Engineer a water truck will be on site to support finish and tilling operation.
CONSTRUCTION METHODS
A. General
It is the primary purpose of this specification to secure a completed course of treated material that contains
the following:
1. Uniform flyash/soil mixture with no loose or segregated areas;
2. Uniform density and moisture content
3. Is well bound for its full depth
4. A smooth surface suitable for placing subsequent courses.
It shall be the responsibility of the Contractor to regulate the sequence of his work; to process a sufficient
quantity of material to achieve full depth as shown on plans; to use the proper amounts of flyash; to maintain
the work; and to rework the courses as necessary to meet the above requirements at no additional cost.
Before other construction operations are initiated, the sub-grade shall be graded and shaped to enable the flyash
treatment of materials in place, in conformance with the lines, grades, and thickness shown on the plans.
Ziegler Road / KechterRoad Roundabout Project
P:\Street Oversizing\Ziegler Road Kechter Road Roundabout\Bid Docs\Construction Specs\Technical Specs
Technical Specs - 17
Unsuitable soil or materials shall be removed and replaced with acceptable material.
The sub-grade shall be firm and able to support, without displacement, the construction equipment and the
compaction hereinafter specified. Soft or yielding sub-grade shall be corrected and made stable by scarifying,
adding flyash, and compacting until it is of uniform stability.
If the Contractor elects to use a trimming machine that will remove the sub-grade material accurately to the
secondary grade, he will not be required to expose the secondary grade or windrow the material. However, the
Contractor shall be required to roll the sub-grade, as directed by the Engineer, before using the trimming
machine and correcting any soft areas that this rolling may reveal. This method will be permitted only where a
machine is provided which will ensure that the material is cut uniformly to the proper depth and which has
cutters that will plane the secondary grade to a smooth surface over the entire width of the cut. The machine
shall be of such design that visible indication is given at all times that the machine is cutting to the proper depth.
B. Application
The flyash shall be spread by an approved spreader at the rate of 12% dry weight of soil as shown on the plans
and as directed by the Engineer. A motor grader shall not be used to spread the flyash.
The flyash shall be distributed at a uniform rate and in such manner as to reduce the scattering of fly sh by wind
to a minimum. Flyash shall not be applied when wind conditions, in the opinion of the Engineer, are such that
blowing flyash becomes objectionable to traffic or adjacent property owners.
During final mixing, water shall be added to the materials as directed by the Engineer, until the proper moisture
content has been secured. Water shall be added through the pulverizing machine or method acceptable to the
Engineer to develop a uniform, controlled rate addition of the needed moisture. Initial mixing after the addition
of flyash will be accomplished dry or with a minimum of water to prevent flyash balls. Final moisture content
of the mix, prior to compaction, shall not exceed the optimum moisture content of the mix by more than two
percent nor by less than the optimum by more than four percent. Should the natural moisture content of the soil
be above the specified range, aeration of the soil may be required prior to addition of the flyash.
C. Mixing
The soil and flyash shall be thoroughly mixed by approved rotary mixers or other approved equipment, and the
mixing continued until, in the opinion of the Engineer, a homogeneous, friable mixture of soil and flyash is
obtained, free from all clods or lumps. Water required to achieve the specified moisture content for the mixture
should be added after initial mixing.
If the soil flyash mixture contains clods, they shall be reduced in size by raking, blading, disking, harrowing,
scarifying or the use of other approved pulverization methods so that when all non-slaking aggregates retained
on the No. 4 sieve are removed, the remainder of the material shall meet the following requirements when tested
at the field moisture condition or dry by laboratory sieves:
Minimum Passing: 1inch sieve 100 percent
Minimum Passing: No. 4 sieve 60 percent
D. Compaction
Compaction of the mixture shall begin immediately after mixing of the flyash and be completed within one hour
following addition of flyash and water. The material shall be sprinkled as necessary to maintain the optimum
moisture. Compaction of the mixture shall begin at the bottom and shall continue until the entire depth of
mixture is uniformly compacted to a specified density.
All non-uniform (too wet, too dry or insufficiently treated) areas which appear shall be corrected immediately
by scarifying the areas affected, adding or removing material as required and reshaping the re-compacting by
sprinkling and rolling. The surface of the course shall be maintained in a smooth condition, free from

Technical Specs - 18
undulations and ruts, until other work is placed thereon or the work is accepted.
The stabilized section shall be compacted to the extent necessary to provide the density specified below:
Description
For flyash treated sub-grade, existing sub-base
or existing base that will receive subsequent
sub-base or base courses
Not less than 95 percent maximum pry density (ASTM
D-698)
For flyash treated sub-base or base that will
receive surface course
Not less than 95 percent maximum dry density
(ASTM D-698)
In addition to the requirements specified for density, the full depth of the material shown on the plans shall be compacted
to the extent necessary to remain firm and stable under construction equipment. After each section is completed, the
Engineer will make tests as necessary. If the material fails to meet the density requirements, the Engineer may require it
to be reworked as necessary to meet those requirements or require the Contractor to change his construction methods to
obtain required density on the next section. Throughout this entire operation, the shape of the course shall be maintained
with a blade, and the surface, upon completion, shall be smooth and in conformity with the typical section shown on the
plans and to the established lines and grades. Grading should be terminated within two hours after blending of the flyash.
Should the material, due to any reason or cause, lose the required stability, density and finish before the next course is
placed or the work is accepted, it shall be reprocessed, re-compacted and refinished at the sole expense of the Contractor.
Reprocessing shall follow the same pattern as the initial stabilization, including the addition of flyash.
E. Finishing, Curing and Preparation for Surfacing
After the final course of the treated sub-grade, sub-base or base has been compacted; it shall be brought the
required lines and grades in accordance with the typical sections.
1. The resulting base surface shall be thoroughly rolled with a pneumatic tire roller and “clipped”, “skinned” or
“tight bladed” by a power grader to a depth of approximately 3 inch, removing all loosened stabilized
material from the section. Re-compaction of the loose material should not be attempted. The surface shall
then be thoroughly compacted with the pneumatic roller, adding small increments of moisture as needed
during rolling. If plus No. 4 aggregate is present in the mixture; one complete coverage of the section with
the fat wheel roller shall be made immediately after the “clipping” operation. When directed by the
Engineer, surface finishing methods may be varied from this procedure provided a dense, uniform surface,
free of surface compaction plans, is produced. The moisture content of the surface material must be
maintained within the specified range during all finishing operations. Surface compaction and finishing
shall proceed in such a manner as to produce, in not more than two hours, a smooth, closely knit surface,
free of cracks, ridges or loose material conforming to the crown, grade and line shown on the plans.
2. After the flyash treated course has been finished as specified herein, the surface shall be protected against
rapid drying by either of the following curing methods for a period of not less than three days or until the
surface or subsequent courses are placed:
(a) Maintain a thorough and continuously moist condition by sprinkling.
(b) Apply a two-inch layer of earth on the completed course and maintain in a moist condition.
(c) Apply an asphalt membrane to the treated course, immediately after same is completed. The
quantity and type of asphalt approved for use by the Engineer shall be sufficient to completely
cover and seal the total surface of the base between crown lines and all voids. If the Contractor
elects to use this method, it shall be the responsibility of the Contractor to protect the asphalt
membrane from being picked up by traffic by either sanding or dusting the surface of same. The
asphalt membrane may remain in place when the proposed surface or other base courses are
placed. Asphaltic emulsions are not acceptable for the asphaltic membrane.

approval to the Traffic Division by 12:00 noon, two working days prior to the commencement of work. (Note:
Traffic Control Plans for work done on Monday and Tuesday shall be submitted the previous Friday by 9:00
a.m.). Facsimiles of plans shall not be allowed. No phase of the construction shall start until the Traffic Control
Plan has been approved. Failure to have an approved Traffic Control Plan shall constitute cause for the City to stop
work, as well as the Contractor's forfeiture of payment for all work and materials at that location, with no adjustment
in the contract time.
The Traffic Control Plan shall include, as a minimum, the following:
(1) A detailed diagram which shows the location of all sign placements, including advance
construction signs (if not previously approved), fines doubled for speeding signs and speed limit
signs; method, length and time duration for lane closures, and location of flag persons.
(2) A tabulation of all traffic control devices shown on the detailed diagram including, but not limited
to: construction signs; vertical panel; vertical panel with light; Type I, Type II, and Type III
barricades; cones; drum channeling devices; advance warning flashing or sequencing arrow panel.
Certain traffic control devices may be used for more than one operation or phase. However, all
devices required for any particular phase must be detailed and tabulated for each phase.
(3) Number of flaggers to be used.
(4) Parking Restrictions to be in affect.
Approval of the proposed method of handling traffic is intended to indicate minimum devices needed to control
traffic. Such approval does not relieve the Contractor of liability specifically assigned to him under this contract.
Parking Restrictions shall be clearly shown on the Traffic Control Plan, including the location and quantity of "NO
PARKING" signs, the date to be placed, and the date to be removed. Failure to have an approved Traffic Control
Plan, including the Parking Restriction information listed above shall constitute cause for the City to stop work, as

B. Tablet method.
1. The tablet method consists of placing calcium hypochlorite granules and tablets
in the water main during construction, and filling the main with potable water
when installation is completed.
a. The tablet method shall not be used if trench water or foreign material has
entered the water line, or if the water temperature is below forty-one degrees
Fahrenheit (5o C).
i. If trench water or foreign material has entered the water line, or if the
water temperature is below forty-one degrees Fahrenheit, the
continuous-feed method of chlorination shall be used.
b. The tablet method shall not be used for extensions which are over 1000 feet
in length, or for water lines which are larger than 12-inches in diameter,
without prior permission of the District.
c. During construction, calcium hypochlorite granules shall be placed at the
upstream end of the first section of pipe, at the upstream end of each branch
main, and at 500 feet intervals.
i. The quantity of granules used shall be as shown in Table 1, AWWA
C651.
d. During construction, 5-gram calcium hypochlorite tablets shall be placed in
each section of pipe, hydrant, hydrant lateral, and other appurtenances.
i. The quantity of tablets used shall be as shown in Table 2, AWWA
C651.
e. Tablets and granules shall be placed in sufficient number and amount to
produce a minimum chlorine concentration in the treated water of 50
milligrams per liter.
05-089.05 01656-4
f. Except in hydrants and joints, tablets shall be attached with an approved
adhesive, and shall be on the top of the interior of the pipe in such a manner
that there is no adhesive on the tablet except on the broad side of the tablet
next to the pipe surface.
i. Reference paragraph 2.1.B.
g. Introduce water into the pipes at a velocity no greater than 1 ft./sec.
h. The chlorinated water shall be retained in the lines for a minimum of 24
hours, at which time the treated water must contain no less than 25
milligrams per liter of chlorine throughout the entire length of the main. The
chlorinated water shall be flushed within five (5) days unless otherwise
approved by the District.
C. Continuous-feed method
1. The continuous-feed method of disinfecting water mains consists of placing
calcium hypochlorite granules in the main during construction, completely filling
the main to remove all air pockets, flushing the completed main to remove the
particulates, and filling the main with potable water chlorinated so that after a 24
hour holding period in the main, there will be a free chlorine residual of not less
than 10 milligrams per liter.
a. Calcium hypochlorite granules shall be placed in the pipe sections during
construction.
i. Reference Section 3.3.B.1.c.
b. Prior to being chlorinated, the main shall be filled to eliminate air pockets,
and shall be flushed to remove particulates. The flushing velocity shall not
be less than 2.5 feet per second.
i. Reference Section 3.2 and AWWA C651.
c. Chlorinated water shall be introduced into the water lines at a point approved
by the District at a constant, measured rate so that the chlorine concentration
is maintained at a minimum of 25 milligrams per liter of free chlorine.
i. The entire main shall be filled with the chlorine solution.
ii. Reference Table 4 of AWWA C651.
05-089.05 01656-5
iii. Prior to and during the disinfection process, valves shall be positioned
so that the chlorine solution in the newly constructed main will not
flow into water mains in active service.
d. The chlorinated water shall be retained in the main for a minimum of 24
hours, at which time the treated water in all portions of the main shall have a
free residual of not less than 10 milligrams per liter.
3.4 FINAL FLUSHING
A. After the applicable retention period, the heavily chlorinated water shall be flushed
from the water lines until the chlorine measurements show that the concentration in the
water leaving the main is no higher than that generally prevailing in the system, or is
less than 1 milligram per liter. The Contractor shall be responsible for all necessary
permits and to ensure that no environmental damage occurs.
1. Reference Appendix B of AWWA C651, for a list of neutralizing chemicals.
3.5 BACTERIOLOGICAL TESTS
A. The District shall collect samples from the pipeline after final flushing and pressure
testing, but prior to placing water lines in service, to test for bacteriological quality to
show the absence of coliform and heterotrophic organisms.
1. The District shall be given a minimum of 48 hours advance notice, prior to
collecting samples.
B. The number and frequency of samples shall be determined by the District based upon
AWWA C651.
3.6 REPETITION OF PROCEDURE
A. If the initial disinfection, or subsequent disinfections, fail to produce satisfactory
samples, the main shall be re-flushed and re-sampled. If the samples are still not
satisfactory, the main shall be re-chlorinated by the continuous-feed or the slug method
of chlorination until satisfactory results are obtained.
