HomeMy WebLinkAbout041823-03.1 FINANCE COMMITTEE MEMORANDUM 3.1
TO: Mayor and Town Council April 18, 2023
SUBJECT: Authorize the Town Manager to execute a Professional Services
Agreement with ENGEO for biological monitoring, and laboratory and
field testing services during construction of the Diablo Road Culvert
Emergency Replacement Project, CIP No. A-330
BACKGROUND
The Town recently awarded a construction contract for the Diablo Road Culvert
Emergency Replacement Project, Contract No. A-330, to Teichert Construction, Inc. of
Pleasanton, California. The project consists of removing and replacing of an existing 12-
ft diameter CMP culvert.
DISCUSSION
The Town has previously established a Quality Assurance Program (QAP), a sampling
and testing program that will provide assurance that the materials and workmanship
incorporated into each construction project is in conformance with the contract
specifications. Some of the testing includes hot mix asphalt (HMA) materials, and soils
and aggregate base compaction. Field testing will be performed in accordance with
AASHTO (American Association of State Highway and Transportation Officials), ASTM
(American Society of Testing and Measurement), or Caltrans (CT) standards.
During the emergency replacement project, there was a need for biological monitoring,
and laboratory and field testing services during the construction phase. On March 30,
2023, ENGEO submitted a proposal with a not to exceed budget of $49,500 to provide the
desired biological monitoring and laboratory and field testing services. The proposal and
rate schedule is included as Attachment A.
Consistent with the Town’s Purchasing Policy, the total not to exceed budget of $49,500
requires authorization from the Finance Committee. Sufficient funds have been
appropriated in the approved 2022/23 Capital Improvement Program for CIP A-330
(Attachment B) to cover the contract costs.
It is recommended that the Finance Committee approve a contract not to exceed $49,500
to ENGEO for laboratory and field testing services.
