FAQ's

WSE Sydney specializes in detailed cost estimation for water and sewer infrastructure projects across Australia. We handle everything from reticulation networks and water main installations to sewer diversions, DTC handle bars, manholes, and more. Our estimates are accurate, compliant, and tailored to each project’s technical and logistical needs.

No, we estimate all water and sewer projects, not just those under Sydney Water. This includes council-managed works, regional infrastructure, and private subdivision developments. We adjust our estimates based on the relevant authority’s specifications.

Yes, we provide estimates for new subdivision networks as well as upgrades to existing infrastructure. We understand the differences in complexity, from greenfield installations to tight urban upgrades around live services.

To provide an accurate estimate, we typically require:

• All tender docs
• We will coordinate with you for more information when required

Yes, our estimates are comprehensive. You will get a complete breakdown of:

• Materials

• Labor

• Plant

• Durations

• Our goal is to make your life easier

We can provide both, depending on your preference. Most clients request itemized breakdowns to better understand individual cost components, especially for tendering or internal approvals.

Absolutely. We offer revised estimates for design changes, variations, or scope adjustments. Just send us the updated drawings or changes, and we’ll adjust the pricing accordingly.

We estimate all types of water infrastructure, including:

• Potable water mains

• Recycled water networks

• Lead-ins and mains to meters

• Reticulation in subdivisions

• Underbores & HDD’s

• Pumping stations and chambers

• Bigger diameter mains

• Works in the regional areas
• Works in paddocks
• Works along live road

Yes. Our estimates include DTC Handle Bars, long section profile analysis, hydrants, gate valves, spindles, and concrete chambers where required. We understand how each element impacts cost, time, and site complexity.

Yes. We regularly estimate deep gravity sewers, including concrete manholes, custom manhole designs, and protective liners. We also include shoring, excavation in different ground conditions, and Level 1 geotechnical testing where required.

Yes. For trenches deeper than 1.5m (or as required), we include shoring box hire, geotechnical compaction testing, and Level 1 supervision for deeper installations (>3m). These are essential for safety and compliance on deep trench jobs.

Definitely. We have experience estimating underbores (including launch and receiving pits) and custom manhole structures. These high-risk elements are priced carefully to reflect real construction conditions and required support systems.

Yes. We follow all relevant Sydney Water DTCs, standards, and specifications. Our team is well-versed in the technical details, so your estimate reflects what will be approved and built without surprises.

Yes. We understand the responsibilities differ. Estimates for Principal Contractors include additional elements like traffic control, site amenities, permits, and project risk, while Subcontractor estimates focus purely on scope execution under a principal.

Typical turnaround is 2–4 business days, depending on project size and complexity. We also accommodate urgent requests, especially for tenders with tight deadlines.

Yes. Let us know your deadline, and we’ll prioritize accordingly. We understand the pressures of tendering and construction schedules and do our best to meet urgent timeframes.
