Job Description
Construction Delivery Manager - Wastewater
n
The Construction Delivery Manager – WWTP Systems is responsible for turning completed engineering designs into efficiently built, installed and handed-over wastewater treatment systems.
n
This role requires a minimum of 4-5 years of construction management experience.
n
Working within Waterform's Solve, Support, Sustain methodology, this role sits at the critical point between engineering, factory production, procurement, site construction, subcontractors and commissioning. The role ensures that large water & wastewater treatment projects are built safely, practically, commercially and with minimum fuss.
n
The role is involved early enough to influence constructability, value engineering, scope clarity, trade packaging, risk identification and construction sequencing. It then leads the construction delivery phase through to
mechanical/electrical
completion and supports the commissioning team up to wet commissioning, before closing out construction-related defects.
