The underground firewater piping system at a client’s mine south of Lake Wabamun, Alberta, had corroded and required replacement. ONEC was contracted to engineer and replace the underground system with new HDPE piping, hydrants, and post indicator valves. This project had road crossings and over 100 piping and electrical crossings to be managed by our construction teams.

Involvement: EPC

A client requested that four existing community recreational arena facilities are to undergo rehabilitation. In order to prepare drawings and other essential documents for the required design repairs of the four arenas, ONEC performed building condition assessment (Architectural, Structural, Civil, Mechanical, Electrical) for developing in-depth scope of work packages for the facilities. ONEC also performed a Energy Audit on each of the four arenas to aid in understanding the energy dynamics within the building and to provide an insight of opportunities for improvement and energy savings. In order for subsequent design repairs to be developed, ONEC discussed all known issues with the client and prioritized them based on urgency of maintenance requirements. A detailed scope of work packages was developed, upon final agreement of scopes, followed by preliminary construction cost estimates and schedule.

ONEC was contracted by a long-term client to provide engineering design services for ash tunnel modifications at a power plant near Wabamun, Alberta. Through extensive consultation with project stakeholders, ONEC conducted an extensive structural assessment program of the ash tunnels and provided the client with a retrofitting structural design for the modifications required.
