Attention: Mr. Josh Holbrook
Construction Inspection Supervisor
Subject: Revised Proposal and Fee Estimate for Quality Assurance (QA)
Materials Testing Services
Weld County Road 74 Mill and Overlay
Weld County, Colorado
Proposal No. FC 09-0312R
At your request, CTLIThompson, Inc. is pleased to provide this revised proposal and fee
estimate for QA Materials Testing services for the Weld County Road 74 mill and overlay
project (Federal Aid Project NO ES4 C030-035, SA 17325) in Weld County, Colorado.
For preparation of this proposal, you provided us with bid quantities. Our revisions
include a fee estimate for performing Hveem stability, air voids, voids in mineral
aggregate, lottman, pavement smoothness testing, and hydrated lime testing.
We anticipate that Weld County will use our estimate for the basis of establishing a
budget for the project and to issue a purchase order for our services. Our estimated
scope of services and associated fees are presented below. We will provide our
services in accordance with the terms and conditions contained in our professional
services agreement with Weld County (Weld County Proposal No. B07-00069; executed
April 17, 2007 and Addendum letter dated February 2, 2009).
We understand Weld County does not have a formal outline of what is required for QA
materials testing. We have elected to use the Frequency Guide Schedule for minimum
materials sampling, testing, and inspection as outlined in the 2009 CDOT Field Materials
Manual to estimate what QA materials testing should be performed and at what
frequency. We estimate the following.
Earthwork: The bid quantities indicate approximately 891 tons of aggregate base course
(Item No. 304) is planned for this project. We estimate the following.
Engineering Technician (In -place Density)
1 day x 3 hrs/day x $60/hr
$180
Moisture -Density Curve (Modified Proctor)
1 test x $110/ea
$110
L.A. Abrasion
1 test x $100/ea
$100
AASHTO Classification (Atterberg Limits and
Gradation)
1 test x $120/ea
$120
Subtotal:
$510

Proposal
CTLITHOMPSON
Asphalt Testing: The bid quantities indicate approximately 2,328 tons of HMA (Grade S)
(75) (PG 64-22) and approximately 4,318 tons of HMA (Grade SX) (75) (PG 64-22) is
planned for this project (Item No. 403). We assumed one set of volumetric testing for
each mix and we also assumed no QA testing would be necessary for the asphalt
patching. As stated in the CDOT manual, testing for pavement smoothness shall be
performed by the contractor and witnessed by the engineer. We can serve as the
engineer for this project or your representative could also serve as the engineer. We
estimate the following.
Asphalt Content
8 tests x $170/ea
$1,360
Aggregate Moisture
3 tests x $30/ea
$90
Gradation
3 tests x $70/ea
$210
Micro Deval
2 tests x $200/ea
$400
Fractured Faces
2 tests x $200/ea
$400
Engineering Technician (In -place Density)
8 days x 4 hrs/day x $60/hr
$1,920
Longitudinal Joint Density
1 day x 8 hrs/day x $100/hr
$800
Theoretical Maximum Specific Gravity
8 tests x $100/ea
$800
Hveem Stability (includes voids & VMA)
2 tests x $250/ea
$500
Lottman
2 tests x $390/ea
$780
Pavement Smoothness
Performed by the Contractor
$0
Hydrated Lime
2 tests x $30/ea
$60
Subtotal:
$7,320
TOTAL ESTIMATED FEE;
7,830
It should be emphasized that this estimate is based upon assumptions of actual
quantities and contractor's schedule. The fee will be charged only for the actual hours
and unit rates presented for tests and observations requested by the owner, contractor
or subcontractors who schedule the services.
If we can be of further assistance, please contact us at your convenience.
Very truly yours,
CTL I Thompson, Inc.
