About this file

Written by GovTribe AI · Dec 27, 2023

This document provides details for a federal contract solicitation. The solicitation is for the Moose Creek Dam Safety Modification project to construct a mix-in-place barrier wall in the embankment of Moose Creek Dam at the Chena River Lakes Flood Control Project. The barrier wall will be between 4.5 to 5.5 miles long, between 22 to 36 inches wide, and have an unconfined compressive strength of 200 psi within 28 days and approximately 500 psi long term. It will be constructed using Portland cement and bentonite. The solicitation is a full and open request for proposal conducted using a single phase source selection tradeoff process as described in FAR 15.101-1. The award will be made based on best overall value considering non-price factors and price. The Department of the Army Corps of Engineers Engineering District Alaska is the contracting agency. A pre-proposal site visit has been scheduled as detailed in clause 52.236-27 of the solicitation.

CONSTRUCTION. TOP OF WALL MUST BE NO LESS THAN

ELEVATION 526. SEE B1 / C-304 AND F1 / C-304.

2. SEE SHEET C-601 FOR POINT TABLES WITH MORE INFORMATION

ON PIEZOMETERS, MONITORING WELLS, THERMISTORS AND

RELIEF WELLS.

3. ABANDONED DIRECT BURIED POWER AND COMMUNICATIONS

LINES IN DAM CREST EXPOSED BY EXCAVATION, MUST BE

REMOVED AND DISPOSED OF BY CONTRACTOR.

4. CONTRACTOR MUST CUT EXPOSED UTILITY LINES AT EACH END

OF EXCAVATION.

5. SEE SPECIFICATIONS FOR DEMONSTRATION SECTION LOCATION

AND REQUIREMENTS.

6. THE CONTRACTOR MUST DETERMINE GROUND WATER LEVELS

PRESENT DURING CONSTRUCTION AND ADJUST PROCEDURES

AS NECESSARY TO MEET CONTRACT REQUIREMENTS.

7. REFERENCE SECTION 35 73 20.00 29 FOR ADDITIONAL

FOUNDATION, EMBANKMENT, AND GROUND WATER TABLE

8. DURING THE CRREL GEOPHYSICAL INVESTIGATION,

DISCONTINUOUS PERMAFROST WAS INTERPRETED TO EXIST

BETWEEN MOOSE CREEK DAM STATIONS 245+00 AND 310+00

BELOW ELEVATION 475 FEET NAVD88. THE CONTRACTOR MUST

ANTICIPATE ENCOUNTERING PERMAFROST WHILE INSTALLING

AT LEAST 1,600 SQUARE YARDS OF BARRIER WALL BETWEEN

STATIONS 245+00 AND 310+00. EXPECT PERMAFROST SOIL

TEMPERATURES BELOW ELEVATION 475 FEET NAVD88 TO RANGE

BETWEEN 30.00 AND 31.99 DEGREES FAHRENHEIT. EXPECT

COMPRESSIVE STRENGTH OF PERMAFROST TO RANGE

BETWEEN 150 AND 600 POUNDS PER SQUARE INCH (PSI). THE
