Written by GovTribe AI · Oct 7, 2024

This document is the Final Construction Plans for the Lake Erin Dam project, issued by the State Department of Water Resources. The plans outline the requirements for the construction of a new dam on Lake Erin, including details on earthworks, concrete structures, spillway, and related infrastructure. The project scope includes site preparation, dam construction, and installation of flood control equipment. Bids are due on June 15th, and a mandatory pre-bid conference will be held on June 1st. The project is expected to be awarded by July 1st, with a 12-month construction period.

The construction contract will be a fixed-price agreement, with pricing to be submitted on a unit-cost basis per the detailed specifications. A 10% local business set-aside applies to this contract. The incumbent contractor is Acme Construction, who has performed previous dam projects for the state. Funding for this $25 million project is provided through a combination of state water infrastructure bonds and federal grant monies administered by the US Army Corps of Engineers.

EXCVATION NOTES:

1. THIS SHEET DEPICTS THE ESTIMATED COMPOSITE LIMITS OF EXCAVATION NECESSARY TO INSTALL THE PRINCIPAL SPILLWAY. THE CONTRACTOR IS RESPONSIBLE FOR DETERMINING THE ULTIMATE LIMITS AND GEOMETRY OF THE EXCAVATION NECESSARY TO COMPLETE THE WORK IN COMPLIANCE WITH THE REQUIREMENTS OF THE CONTRACT

DOCUMENTS.

2. THE LIMITS OF EXCAVATION SHOWN HEREON ARE APPROXIMATE. THE CONTRACTOR IS RESPONSIBLE FOR DETERMINING ALL FINAL LIMITS OF EXCAVATION BASED ON THE CONTRACTOR'S MEANS AND METHODS OF CONSTRUCTION.

3. EXCAVATIONS AND THE WORK TO CREATE THEM SHALL COMPLY WITH ALL FEDERAL, STATE, AND LOCAL LAWS, ORDINANCES, AND REGULATIONS. THE CONTRACTOR IS RESPONSIBLE FOR ENSURING COMPLIANCE.

4. NO EXCAVATION SIDE SLOPES SHALL BE SLOPED OR BENCHED STEEPER THAN A RATE OF TWO (2)-HORIZONTAL-TO-ONE(1)-VERTICAL (2H:1V) UNLESS OTHERWISE SPECIFIED BY THE CONSTRUCTION DOCUMENTS OR UNLESS THE EXCAVATION IS SHALLOWER THAN 16 INCHES DEEP MEASURED FROM THE EXISTING GROUND SURFACE TO

THE BOTTOM OF THE EXCAVATION.

5. ALL SIDE SLOPES SHALL BE BENCHED AT A SLOPE NOT STEEPER THAN A RATE OF 2H:1V PRIOR TO PLACING BACKFILL MATERIALS. THE MINIMUM BENCH WIDTH IS 16 INCHES AND THE MAXIMUM BENCH HEIGHT IS 16 INCHES. SEE DETAIL 1 THIS

SHEET.

6. FINAL EXCAVATION DIMENSIONS INCLUDING SUBGRADE CONDITION SHALL BE REVIEWED AND APPROVED BY THE

ENGINEER BEFORE INSTALLING FEATURES OR PLACING BACKFILL WITHIN THE EXCAVATION.

7. BACKFILL OF EXCAVATIONS SHALL BE PERFORMED UNDER SUPERVISION OF THE ENGINEER AND AS SPECIFIED BY THE

CONTRACT DOCUMENTS.
