Scope and delivery
Stormwater & Drainage Infrastructure
Drainage is a core civil system. We deliver channels, culverts, subsoil drainage, erosion protection, attenuation interfaces and site grading that move water safely and protect completed infrastructure.
How we structure the work
Project delivery starts by defining the work package, design and construction responsibility boundaries, interfaces with specialist contractors, site constraints, quality requirements, HSEQ controls and programme milestones. This allows construction methods, temporary works, procurement and mobilisation to be aligned before execution.
What to include in an enquiry
For an efficient review, share the project location, tender or scope document, drawings and specifications where available, quantities or bill of quantities, target programme, procurement route, HSEQ requirements and any operating-site constraints.
Big Three Engineering is headquartered at 1 Chadwick Avenue, Wynberg, Sandton, Johannesburg and receives project and tender enquiries for infrastructure work across South Africa.
Answers
Frequently asked questions
Concise answers for tender teams, project managers, developers and consultants.
What types of stormwater infrastructure can Big Three Engineering construct?
Typical scope includes culverts, channels, lined drains, subsoil drainage, erosion protection and interfaces with attenuation and discharge structures.
Is drainage included with roads and earthworks packages?
It can be. Integrating drainage with road formation and earthworks often improves sequencing and interface control.
Can drainage works support mining and industrial sites?
Yes. Mine roads, plant platforms, hardstands and industrial yards all depend on reliable water management and erosion control.
What information is needed to price drainage work?
Useful inputs include drainage drawings, catchment or hydraulic design information, quantities, material specifications, outlet details, access constraints and programme requirements.
