The San Diego County Water Authority is requesting proposals for the following design-build project.

I. PROJECT:

A. Title:

Lake Hodges Hydroelectric Facility Isolation Project, Design-Build

Specification 695

B. Owner:

San Diego County Water Authority

C. Location:

The project site is situated in the City of Escondido, between Lake Hodges and

II. CONTRACT DOCUMENTS:

Please visit https://www.sdcwa.org/contracting-opportunities for general information and for a link

III. PROJECT DESCRIPTION:

A. Scope of Work: The San Diego County Water Authority (Water Authority) is soliciting proposals

from qualified Design-Builders experienced in the design and construction of subaqueous steel

bulkheads for the Lake Hodges Hydroelectric Facility Isolation project (Project).

Over time, the existing isolation slide gates at the Lake Hodges Hydroelectric Facility have

deteriorated and are no longer fully functional, impeding maintenance efforts and posing safety risks.

The proposed project will design and install welded steel bulkheads that will hydraulically isolate the

hydroelectric facility’s penstocks and intake from Lake Hodges, allowing dewatering, inspection, and

maintenance of the facility.

The installation of subaqueous steel bulkheads at the Lake Hodges Hydroelectric Facility is highly

specialized work that must be performed underwater at significant depth. It requires certified

commercial divers who are also qualified underwater welders meeting strict American Welding

Society (AWS) D3.6M Class A standards, along with nondestructive testing technicians holding

advanced certifications for inspecting welds in a submerged environment.

B. Liquidated Damages: If work is not completed by the Contractor by each scheduled milestone or

completion date specified in the Contract Documents, the Water Authority will assess liquidated

damages in the amount of $1,000 for each calendar day or portion thereof until work is complete.

Please review the Contract Documents.

C. Required Insurance Coverage:

1. Commercial General Liability $5,000,000 per occurrence

2. Automobile Liability

$5,000,000 per occurrence
