involved in the project and complete it by filling in the subcontractor’s name and address and
signing it.
The original Certificate should always be retained by the prime contractor. Copies of all
Certificates that the prime contractor issued to subcontractors should be kept at the prime
contractor’s place of business for a minimum of three years and be available for inspection in
the event of an audit.
Once an 89# has been assigned to you, please use the next five numbers following it for any
applications submitted for future projects. This should be your permanent number. For
instance, if you were assigned 89-12345-0001, every application submitted thereafter should
contain 89-12345 on the application. The succeeding numbers will be issued by the
Department of Revenue. DO NOT enter what you believe to be the next in sequence as this
may delay processing of your application.

SUMMARY OF WORK
PART 1 GENERAL
1.25 Modifications to Time of Completion in the Approved Schedule
A. The date of beginning and the time 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 "Normal" weather and climate
conditions 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.
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 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 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 Engineer in writing of
Timberline Road & Kechter Road
Right Turn Lanes
6
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.
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 work days 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.
The Contractor’s schedule must reflect the above-anticipated adverse weather delays on all
weather-dependent activities. 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.
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.
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.

removed in a manner that minimizes contamination of the removed mat with underlying
material. The removed mat shall be hauled by the Contractor and disposed of at the City’s
Hoffman Mill asphalt recycling facility (1380 Hoffman Mill Road, Fort Collins). Where the
removed asphalt mat abuts asphalt to remain, the asphalt mat shall be sawcut full depth to a
neat vertical line.
Subsection 202.11 shall include the following:
The removal of the existing asphalt mat will be measured by the square yard of mat removed to
the required depth and accepted.
Sawcutting will not be paid separately and shall be included in the cost for removal of asphalt
mat.

REVISION OF SECTION 207
TOPSOIL (STOCKPILE AND REDISTRIBUTE)
Section 207 of the Standard Specifications is hereby revised for this project as follows:
Subsection 207.01 is hereby revised to include the following:
This work consists of removing existing on-site topsoil material, stockpiling the existing topsoil
material and redistributing the existing topsoil material onto the re-graded slopes at a depth of 4
inches (minimum). The topsoil material shall be generally evenly distributed throughout the
project limits. Any excess topsoil generated from this project shall be disposed of off-site and
shall not be measured and paid for separately, but should be included in the cost of work.
Subsection 207.03, paragraph 3 shall include:
Per City Code, soil shall be loosened to a depth of not less than eight (8) inches. The Engineer
shall be notified if this cannot occur due to existing conditions.

REVISION OF SECTION 401
TEMPERATURE SEGREGATION
Section 401 of the Standard Specifications is hereby revised for this project as follows:
In subsection 401.16 delete the twelfth (last) paragraph and replace it with the following:
The Engineer may evaluate the HMA for low density due to temperature segregation any time industry
best practices, as detailed on Form 1346, are not being followed or the Engineer suspects temperature
segregation is occurring. The Engineer will first meet with the Contractor to discuss the paving
practices that are triggering the temperature investigation. Areas across the mat, excluding the outside
1 foot of both edges of the mat, that are more than 25 °F cooler than other material across the width
may be marked for density testing. Material for temperature comparison will be evaluated in 3-foot
intervals behind the paver across the width of the mat. The material shall be marked and tested in
accordance with CP 58. If four or more areas within a lot of 500 tons have densities of less than 93
percent of the material’s maximum specific gravity for SMA mixes or less than 92 percent of the
material’s maximum specific gravity for all other HMA mixes, a 5 percent price disincentive will be
applied to the 500 ton lot. The 500 ton count begins when the Engineer starts looking for cold areas,
not when the first cold area is detected. This price disincentive will be in addition to those described in
Sections 105 and 106. Only one area per delivered truck will be counted toward the number of low
density areas. Temperature segregation checks will be performed only in areas where continuous
paving is possible.

Note: Since the permeability coefficient of the soil will be unknown in most
non-critical, non-severe applications for erosion control and
drainage, the soil-permeability coefficients listed in Table 712-2 may
be used as a guide for comparing the permeability coefficient of the
fabric with that of the in-place soil
