SECTION 02016 - EXISTING UNDERGROUND UTILITIES

A. Locate existing utilities for disconnection and reconnection of modular barracks utilities.

1.02 PROTECTION OF UTILITIES

A. It should be noted that the Forest Service compound contains several generations of existing underground utilities (i.e. sewer, water, gas, electric, etc.). Many of these utilities are currently in service, and some have been abandoned. The contractor should expect to encounter many unknown utilities during the course of construction. It will be the contractor’s responsibility to locate and identify existing utilities prior to excavation to minimize impacts to the station occupants and the Contractor during construction.

B. Should damage occur to an existing utility, repairs shall be performed as directed by the Contracting Officer. The Contractor is responsible to repair identified and unidentified utilities at no additional cost to the government.

2.01 UTILITIES AFFECTED

A. General

The Underground Service Alert (USA), (800) 642-2444, shall be contacted at least 72 hours before any work commences. Note that USA will not locate underground utilities within Forest Service Compounds.

B. Gas, Electric and Phone

PG&E provides electric service at Mad River and Orleans. Gas service is through Campora at

Mad River and Amerigas at Orleans. Telephone is through Verizon at Mad River and Orleans.

It should be noted that where overhead electric or phone service does not exist, then underground service shall be assumed to exist.

C. Water and Sewer Service

Water and sewer service is supplied from an onsite system managed by the Forest Service at

Mad River.

Water is connected to the Orleans Community Services District at Orleans. The sewer service at Orleans is an onsite system managed by the Forest Service.

2.02 TEMPORARY FACILITIES

Contractor shall provide temporary facilities as needed to perform the work included in the contract documents.

AG-9AC7-S-14-0111 Page 15 of 57

PART 3 - EXECUTION

3.01 EXISTING UTILITIES

A. The Forest Service will provide the Contractor with as-built plans prior to any utility related work.

3.02 CONTRACTOR RESPONSIBILITY

It may be expected that there will be some variation in location of existing utilities from that as shown on the as-built plans. Actual location can best be determined in the field after pre-marking by the various utilities affected. Contractor is required to contact Underground Services Alert (USA) before beginning any excavations.

The Contractor shall be responsible for determining the location of existing service laterals or appurtenances whenever the presence of such utilities on the site of the construction can be inferred from the presence of other visible facilities, such as building, meter and junction boxes, located on or adjacent to the site.

PART 4 - MEASUREMENT AND PAYMENT

No separate payment shall be made for work specified in this section. Compensation for this work will be considered incidental to Pay Item 00001 – Modular Tear Down and Set Up.
