Item No. 28
September 24, 1998
September 11, 1998
We have estimated the scope of services to be provided for Resident Project Representative (RPR)
services for the referenced project. In addition, compliance testing and confirmation surveying will be
required. RPR services are expected to be provided on a full time basis for approximately ten months.
The scope of anticipated testing services is enclosed. Confirmation surveying services will be provided
on an as needed basis. We propose to subcontract testing and surveying services to Lubbock testing
and surveying firms, Terra Engineers, Inc. and High -Tech GPS & Land Surveyors, Inc.
We propose to provide RPR services on an hourly rate basis under the provisions of EXHIBIT D,
ADDITIONAL SERVICES TO BE PROVIDED BY THE ENGINEER, of the agreement between the
City if Lubbock and Parkhill, Smith & Cooper, Inc. (PSC) dated April 23, 1992. Direct expenses and
reimbursable subconsultant expenses will be paid at cost plus ten percent service charges.
It is expected that time and expenses for RPR, testing and surveying services will not exceed two
hundred and sixty five thousand dollars ($265,000.00), generally split as follows.
RPR - 10 mos. full time $125,000.00
Testing Laboratory $130,000.00
Surveying $10,000.00
These services will be paid on an hourly basis for time and expenses actually expended in accordance
with the updated rates contained in our May 22, 1998 letter (copy enclosed).
Prior to exceeding the amount listed above for RPR, testing and/or surveying services, PSC will notify
the City and additional negotiations will be conducted and additional compensation will be authorized
by the City of Lubbock.

Dear Mark:
May 22, 1998
In accordance with Fee Schedule 2, Additional Services, of the agreement between the City of Lubbock and .
Parkhill, Smith & Cooper, Inc., dated April 23, 1992, an adjustment to the rates of compensation for Additional
Services contained in the agreement is proposed to be applied for services provided under the agreement after
December 31, 1996. The proposed adjustment is based on the increase in the Consumer Price Index from 139.S
in April, 1992 to 116.3 in December, 1997 as follows.
'ARC = IRC x c/139.5
Where:
ARC = Adjusted Rate of Compensation
IRC z Initial Rate of Compensation
c a Consumer Price Index oa which salaries are based at the time Special
Services are furnished after December 31, 1995.
The proposed adjusted rates are as follows.

CONSTRUCTION MANAGEMENT PROGRAM
A. GENERAL DESCRIPTION
The project to be constructed under this program at Lubbock International Airport includes a Base
Bid and one Additive Alternate. The Base Bid provides for the construction of paved shoulders on
air carrier taxiways; construction of perimeter ARFF roads; installation of lighting and signage
improvements; pavement marking; and related items of work.
Additive Alternate A provides for substituting asphalt stabilized base course in lieu of crushed
aggregate base course.
The City of Lubbock, Lubbock International Airport, is the project sponsor.
Sponsor's Representative:
Mr. Quentin Thomas
Deputy Director of Aviation
Route 3 Box 389
Lubbock, Texas 79401-9710
(806) 775-2036
Mr. Thomas will have the overall responsibility for contract administration and the authority to take
necessary action to comply with the contract. The City has retained Parkhill, Smith & Cooper, Inc.,
(PS&C), Consulting Engineers, to provide Construction Phase Services on the project.
As requested, PS&C will also provide a Resident Project Representative (RPR). The duties,
responsibilities and limitations of authority of the RPR are described in Exhibit E of the Professional
Engineering Services Agreement between the City of Lubbock and PS&C dated April 23, 1992.
The RPR will report directly to the PS&C Project Engineer. The testing laboratory will be
responsible for all construction period and material compliance testing on the project. The
Contractor will be responsible for selecting an approved testing laboratory for preconstruction
material compliance testing. The testing laboratory will report all construction period and material
compliance test results to PS&C, Lubbock International Airport and the Federal Aviation
Administration (FAA). The testing laboratory will also report construction period test results to the
Contractor on the project.
B. TESTING OUTLINE
Following is an outline of the materials to be incorporated into this project and tests required by the
contract specifications. Included in the outline is a listing of materials, the ASTM test method,
Texas Test Method or AASHTO test method to be used, the frequency of tests, and the minimum
requirements or tolerances specified.

This Construction Management Program will be made available to the RPR on the site and will be used as
the basis for testing. The testing laboratory will be instructed to follow this program and conduct the
project testing in accordance with the specific test procedures outlined herein. Density testing will be
recorded by the RPR. Testing logs will show test location, type and result. All failing densities will be
retested until passing results are achieved. Failing bituminous surface course tests will be brought to the
attention of the Contractor and appropriate corrective action will be taken by the Contractor. The Project
Engineer for Parkhill, Smith & Cooper, Inc., will determine, in consultation with the City and FAA, the
extent of unacceptable material to be removed and replaced by the Contractor, if necessary. Pay
reduction and incentive factors will be calculated and applied in accordance with the specifications.
