recommending that RMC Water and Environment be retained for these services during the construction. The estimated contract cost is $297,642. • Material and geotechnical testing and observation during trenching and backfill operations are also necessary. These services are required to ensure proper backfill and compaction of the trench line. By testing the compaction of the native backfill material, as well as any import backfill material, we hope to avoid any future settling or other distorting of the trench line. This will protect both the pipeline integrity and the roadway surface. Staff is recommending the use of one of our on-call geotechnical consultants, ENGEO Incorporated to provide the testing at an estimated cost of$67,650. • Biological monitoring is required by the environmental report for the project and by the California Fish and Wildlife Department Streambed Alteration Agreement in the area of the Arroyo Mocho undercrossing. Staff is recommending Pacific Biology provide these services. Pacific Biology has worked successfully for the City in the past providing similar services, and has long history of working successfully with resource agencies. Staff is recommending Pacific Biology be retained to provide all the monitoring and reporting required for the project at an estimated contract cost of$69,540. • There are known (and possible unknown) ancient burial sites in the vicinity of the proposed pipeline construction. During the construction it is required that an archeologist be on site during excavation in the vicinity of the known burial sites. It is also required that we have an archeologist on-call and available should we discover burial sites during construction. Staff is recommending SMB Environmental, Inc be retained for the services at an estimated cost of$10,000. Budget In addition to the construction contract and consultant agreement amounts, staff recommends that the construction contingency amount for this project be set at approximately 10% of the construction contract amount. This contingency will be used in the event that issues arise during the project, such as the potential for unforeseen utilities and objects encountered during excavation.
