NMWSC-Concrete Installation

Background
The contract is issued by the NMWSC as part of a joint funding agreement with the Upper Colorado River Commission (UCRC). The goal of the contract is to design, construct, and operate an Index Velocity Discharge Gage on Citizens Ditch near Hwy 550 in Bloomfield, NM. The project aims to improve data quality by lining the unlined ditch with concrete, which is a significant technical requirement that necessitates a contractor specializing in concrete work within waterways.

Work Details
The scope of the project includes:

- Initial channel survey;
- Channel excavation;
- Concrete form work and securing steel reinforcement;
- Pouring concrete and concrete finishing;
- Concrete form removal and backfilling;
- Site cleanup.

The specifications for the concrete work detail that the downstream end of the rectangular concrete ditch lining will start approximately 70 feet upstream from the Highway 550 culvert opening and extend for about 35 feet upstream. The dimensions of the concrete lining will be approximately 30 feet by 12 feet, located within the ditch bottom. The walls will be vertical and about 5 feet high with a wall thickness of 6 inches. The concrete ditch floor elevation must be within 3 inches at or above the current grade, with wing wall sections tied into the ditch bank at the most upstream end and perpendicular wall sections at the downstream end.

Period of Performance
Construction is expected to start in January 2026, with an expected duration of 2 weeks to meet data collection requirements for the joint funding agreement.

Place of Performance
The construction projects will be performed on Citizens Ditch on the east side of Highway 550 in Bloomfield, New Mexico.
