Million Dam

MATERIALS SPECIFICATIONS

INTRODUCTION

The Bureau of Reclamation, Upper Colorado Region, requires riprap, bedding gravel, ready mix concrete and ready-mix grout for repairs to the spillway at Million Dam, CO. The contractor shall be responsible for delivery of the products to the site, meeting the grain size distribution and standards described in this specification.

QUANTITIES

DELIVERY

Delivery of aggregates will be on a will-call basis as there may not be enough room on site to store all material on site. We’ll start with the bedding material, then take the riprap. Vendor will need to be able to deliver approximately 150 tons per day, starting on or about July 6, 2023, and completing by July 31, 2023. Delivery can be made in single side dumps, truck, and pup, or 10-wheel dump. Delivery of ready-mix concrete and grout will be on a will call basis, toward the latter end of the project, approximate delivery dates of August 7-18, 2023.
