Design and 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.

Scope: Procurement, construction management, construction, and commissioning

Completion: 2016

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, and HVAC and truck loading equipment.

Scope: Multi discipline construction management, safety management, electrical and controls, and subtrades

Completion: 2015

Mine 480V Services

ONEC worked with a client to supply 480 V main service entrances for their mine near Wabamun, Alberta. The project also included installation of 300 kVA and 150 kVA transformers, including provision of engineered drawings.

Scope: Electrical Engineering

Completion: 2010

Turbine Injection Skid

ONEC provided design and construction services for a water injection skid to supply de-ionized water to the NOx skid at the client’s power plant. Working from the client’s conceptual design, ONEC undertook a detailed design of an integrated storage/production/recirculation system to maintain the high purity of de-ionized water during storage.  The water injection skid was fabricated at ONEC’s panel shop in Edmonton.

Scope: Electrical Engineering, Mechanical Engineering, Fabrication

Completion: 2012
