Special Notice
Contractors who have completed this application in the past, please note the following
changes in procedure:
The Department will no longer issue individual Certificates of exemption to
subcontractors. Only prime contractors will receive a Contractor’s Exemption Certificate
on exempt projects.
Upon receipt of the Certificate, the prime contractor should make a copy for each
subcontractor 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

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.

design:
(1) Air Voids
(2) Voids in Mineral Aggregate (VMA).
(3) Asphalt Content (AC).
The test frequency shall be one per day unless altered by the Engineer.
The test results will be evaluated and the Contractor shall make adjustments if required in
accordance with the following:
1. Target Values. The target value for VMA will be the average of the first three volumetric field
test results on project produced hot mix asphalt or the target value specified in Table 403-1 and
Table 403-2 of the specifications, whichever is higher. The target value for VMA will be set no
lower than 0.5 percent below the VMA target on Form 43 prior to production. The target values
for the test element of air voids and AC shall be the mix design air voids and mix design AC as
shown on Form 43.
2. Tolerance Limits. The tolerance limits for each test element shall be:
AC ± 0.3 percent
Air Voids ± 1.2 percent
VMA ± 1.2 percent
3. Quality Levels. Calculate an individual QL for each of the elements using the volumetric field
verification test results. If the QL for VMA or AC is less than 65 or if the QL for air voids is less
than 70, the production shall be halted and the Contractor shall submit a written proposal for a
mix design revision to the Engineer. Production shall only commence upon receipt of written
approval from the Engineer of the proposed mix design revision.
After a new or revised mix design is approved, three additional volumetric field verification tests will
be performed on asphalt produced with the new or revised mix design. The test frequency shall be
one per day unless altered by the Engineer.
If the QL for VMA or AC is less than 65 or the QL for the test element of air voids is less than
70, then production shall be halted until a new mix design has been completed in accordance
with CP 52 or CP 54, a new Form 43 issued, and the Contractor demonstrates that he is
capable of producing a mixture meeting the verification requirements in accordance with A or B
below:
A. The Contractor shall produce test material at a site other than a CDOT project. The
Contractor shall notify the Engineer a minimum of 48 hours notice prior to the requested
68
test. The location and time of the test are subject to the approval of the Engineer, prior to

is equal or greater than 65 and the QL for the element of air voids is equal or greater than
70, full production may resume or;
B. The Contractor may construct a 500 ton test strip on the project. Three samples in the last
200 tons will be tested for volumetric properties. After construction of the test section,
production shall be halted until the testing is complete and element QLs are calculated. If
the QL for VMA or AC is equal or greater than 65 or the QL for the element of air voids is
equal or greater than 70, full production may resume. If the QL for VMA or AC is less than
65 or the QL for the element of air voids is less than 70, the material shall be removed and
replaced at no cost to the Department. The time count will continue, and any delay to the
project will be considered to have been caused by the Contractor and will not be
compensable.

REVISION OF SECTION 401
COMPACTION PAVEMENT TEST SECTION (CTS)
Section 401 of the Standard Specifications is hereby revised for this project as follows:
In subsection 401.17, delete the fifteenth paragraph and replace with the following:
Two sets of random cores shall be taken within the last 200 tons of the CTS. Each set shall consist of
a minimum of seven random cores. The Engineer will determine the coring locations using a stratified
random sampling process. The locations of these cores will be such that one set can serve as a
duplicate of the other. One set of these cores shall be immediately submitted to the Engineer. This set
will be used for determining acceptance of the CTS and determining density correction factors for
nuclear density equipment. Densities of the random samples will be determined by cores according to
CP 44. Density correction factors for nuclear density equipment will be determined according to CP 81.
Coring shall be performed under CDOT observation. Coring will not be measured and paid for
separately but shall be included in the work. For SMA, a CTS is not used. The Contractor shall follow
the requirements for the demonstration control strip in accordance with the Revision of Section 403,

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.
