Design, Build, and Construction Management (DBCM)

ONEC provided full DBCM services for a $13.2M expansion to its biosolids dewatering, storage and unloading facility. The project was operational in less than 1 year from project kickoff and met the client’s schedule and budget for much needed expansion to its ability to handle biosolids from the growing population. The project included new centrifuges, tank modifications, biosolids pumps, silos, buildings, HVAC and truck loading equipment.

Design / Build

ONEC assisted a client with the install of 6MW of generation capacity at the client’s facility. The intent for the project is twofold – one being to consume waste gas and offset environmental concerns and two – to feed power to the grid. ONEC’s responsibility on this project was Engineering, Procurement, Construction and Commissioning.
