Summary of Scope of Work:

Little Goose Dam

Little Goose Lock and Dam is located on the Lower Snake River.  The powerhouse roof has a shallow gabled configuration consisting of a centrally located ridge parallel with the long axis of the powerhouse and a built-in structural slope of ¼-inch per foot from each side of the ridge to the parapet walls.  The roof structure consists of steel wide flange girders spanning the short dimension of the powerhouse and supported on concrete corbels cast integrally with the upstream and downstream concrete walls of the powerhouse. Steel wide flange beams span between the roof girders and 3 inch deep steel decking spans over the beams at a right angle to complete the roof structure.  The present powerhouse roof was installed in 1991 as a replacement for an existing built-up asphalt roofing system.  The roof has 7 bays consisting of the erection bay and six generator bays.  Powerhouse bays are separated by elevated roof contraction joints located directly over the concrete monolith joints of the powerhouse.  Each bay has 4 roof drains.

The roof of the elevator penthouse consists of a poured in place concrete deck. The deck is cast flat, thus, slope is created in the roofing system by means of tapered insulation.  The present roof was installed in 1993 as a replacement for an existing asphalt BUR system.

The scope of the work is to provide a durable waterproofing system for the Little Goose powerhouse and ancillary elevator penthouse roofs. This will be achieved by removing the existing roofing system in its entirety down to the structural roof decks, followed by the installation of a new roofing assembly to include gypsum roof sheathing, a vapor retarder, polyisocyanurate foam roof insulation, a top layer of gypsum roof sheathing. The powerhouse roof will be waterproofed with a 90-mil thick ethylene propylene diene monomer (EPDM) single-ply roofing membrane and, because of large amount of roof-mounted equipment, the elevator penthouse will be waterproofed with a fluid-applied PMMA roofing membrane. Additionally, fall protection guardrails will be installed to the parapet walls of the powerhouse and elevator penthouse roofs to ensure a safe work environment for maintenance personnel conducting preventative maintenance activities on the roofs.

Both roof locations will require improvement to fall protection by installing new steel guardrails to the powerhouse and elevator penthouse parapets.

All on-site work shall be performed in accordance with the Corps of Engineers Safety and Health Requirements Manual (EM 385-1-1).

Establish and manage an effective on-site Safety and Health program in accordance with EM 385-1-1 that will require the development and submission of a comprehensive project specific Accident Prevention Plan for Government acceptance. In addition, develop and submit for Government acceptance Activity Hazard Analyses for each phase of work and a project specific Fall Protection Plan that comply with EM 385-1-1.

A Site Safety and Health Officer (SSHO) employed by the prime contractor is required for each shift of the contractor’s on-site operations. The SSHO shall possess a minimum of 5-years’ experience in construction safety on similar projects, shall have completed the 30-Hour OSHA Construction Safety training within the last 5 years, and shall have completed at least 24 hours of safety training from accredited safety training sources each year for the past 5 years.

Establish and manage an effective Contractor Quality Control (CQC) System that will require the development and submission of a comprehensive project specific CQC Plan for Government acceptance. A CQC System Manager employed by the prime contractor is required to be on-site for each shift of the Contractor’s operations. The CQC System Manager must possess a minimum of 5 years relevant experience in a supervisory or management position such as Quality Control Manager, Quality Assurance Manager, or Construction Manager directly involved in the management of construction quality at the project site.

RMS is a Windows-based program capable of operating on a stand-alone personal computer or on a network. The Government will make the QCS software available to the Contractor at time of notice to proceed.

The project involves the development and management of Contractor furnished submittals for items such as pre-construction plans, product data, test reports, and contract close-out documentation as required by the technical specifications of the contract.
