About this file

This document is a project specification related to a federal construction contract opportunity for the rehabilitation of the Cedar Grove Wastewater Primary Treatment Plant in California's Kings Canyon National Park.

The project involves demolition, removal, and abandonment of existing structures, piping, and site improvements, as well as the installation of new cast-in-place concrete site elements, piping, valves, and wastewater treatment equipment. Key requirements include the use of epoxy-coated reinforcing steel, vapor retarders, waterstops, admixtures, and specific concrete finishing tolerances. The work is set aside for small business concerns, with a construction magnitude of $1,000,000 to $5,000,000. Proposals are due by 12:00 p.m. Pacific Standard Time on May 13, 2024, and the solicitation number is 140P8524R0007.

3.1 INSTALLATION

A. Forms

1. Assemble forms so forms are sufficiently tight to prevent leakage.

2. Properly brace and tie forms.

3. Make proper form adjustments before, during, and after concreting.

4. Use new forms, or used forms that have been cleaned of loose concrete and other debris from previous concreting and repaired to proper condition. Provide smooth liner on forms used for concrete to be exposed if necessary to attain specified finish quality.

5. Use metal cold joint forms when unable to place concrete for footings, foundations, and slabs in continuous pours.

B. Accessories

1. Provide for installation of inserts, templates, fastening devices, and other accessories to be set in concrete before placing.

2. Position anchor bolts for hold-down anchors and columns and securely tie them in place before placing concrete.

C. Expansion Joints: Install at joints between the floor slab and foundation wall where shown on the Drawings.

D. Form Removal: Removal of forms can usually be accomplished in 12 to 24 hours. If the temperature is below 50 deg F or if concrete (stairs, beams, etc) depends on forms for structural support, leave forms intact for a sufficient period for concrete to reach adequate strength.
