Concrete Moulds for Pump Wells

Project Details

DWW Engineering fabricated a set of seven concrete moulds to support the casting of hollow concrete tubular sections used in water and wastewater infrastructure. 

The scope included two mould sizes: 

• Large forms: 4.4 m outside diameter / 3.6 m inside diameter 

• Small forms: 1.6 m outside diameter / 1.2 m inside diameter 

Each mould section measured 1.5 m in height and bolted together around circumferential flanges, allowing reliable assembly and repeat use during casting. 

Our team fabricated all components to DWW Engineering drawings and trial fitted the assemblies prior to dispatch to confirm correct fit-up and bolted alignment before the moulds left the workshop. 

Delivery ran to a staged program, with large diameter moulds: completed in 3 weeks and small diameter moulds completed 2 weeks later.

Highlights

• 7 moulds fabricated for repeat casting of hollow concrete tubular sections
• Two size ranges delivered: 4.4 m OD / 3.6 m ID (large) and 1.6 m OD / 1.2 m ID (small)
• 1.5 m-high sections with bolted circumferential flanges for practical assembly and handling
• Trial fit completed pre-dispatch to confirm assemblies and eliminate site issues
• Staged lead times supported the client’s production schedule: 3 weeks + 2 weeks
