Landmark Gran Central
373 apartments · 25 residential floors · 4-storey podium · 5-level basement
High-rise residential · Granville, Western Sydney NSW
The challenge
Gran Central is one of Western Sydney's most significant residential developments: a 30-level hydraulic scope including a 5-level basement carpark, a 4-storey podium and 25 residential floors with 373 apartments.
The complexity was extraordinary. Cold and hot water services, sanitary drainage, stormwater, gas reticulation and basement carpark drainage all had to be estimated across every riser, every level and every system.
The risk profile on a project this size is enormous. A single missed scope item or incorrect allowance can cost the contractor hundreds of thousands of dollars. There was no margin for error.
The SNZ approach
- ▸Complete PlanSwift digital takeoff from architectural, hydraulic and structural drawings across all 30+ levels
- ▸Individual measurement of every pipe, fitting, fixture, riser and valve, no averaging, no assumptions
- ▸Separate pricing of basement hydraulics including sump pumps, carpark drainage and grease arrestors
- ▸Podium hydraulics treated as a separate scope with independent verification
- ▸Full second-estimator review before delivery, every number independently checked
The outcome
- ✓Delivered on time, the full package within the agreed programme despite the 30+ level scope
- ✓Scope items identified that had been missed in preliminary estimates, protecting the contractor from underpricing
- ✓Numbers held up, with estimate accuracy confirmed as the project progressed through design development
- ✓Client returned to SNZ for subsequent projects, the ultimate measure of accuracy and trust
Queensland Rail — 3 Station Upgrades
Maryborough West · Bundaberg · Rockhampton · estimated concurrently
Government rail infrastructure · Queensland
The challenge
Abergeldie Complex Infrastructure, a national Tier 1 civil contractor, needed hydraulic estimates for three Queensland Rail station upgrades simultaneously at Maryborough West, Bundaberg and Rockhampton.
Government rail infrastructure demands an extraordinary level of compliance, precision and programme discipline. All three sites had to be estimated concurrently under a tight government tender timeline.
Working with a Tier 1 contractor means the standard expected is the highest in the industry. There is no room for approximation on government infrastructure.
The SNZ approach
- ▸All three station scopes estimated concurrently, no sequential delays
- ▸Separate detailed takeoff and pricing for each site from individual drawing packages
- ▸Government compliance requirements built into every line item
- ▸Scope risks identified at each station and flagged to Abergeldie before submission
- ▸Full independent review of all three estimates before delivery
The outcome
- ✓All three estimates delivered on time within the government tender programme, not a single day late
- ✓Scope risks identified and communicated to Abergeldie before tender submission
- ✓Priced to Tier 1 submission standard, so Abergeldie received estimates they could submit directly to Queensland Rail
- ✓SNZ established as a trusted estimating partner for Tier 1 civil contractors
Rio Tinto — Paraburdoo Airport
Remote mine site · off-grid · terminal demolished and rebuilt
Mining & resources · Paraburdoo, Western Australia
The challenge
Paraburdoo is one of Australia's most remote mine sites: extreme heat, no council water, no council sewer, no local suppliers. The airport terminal was being demolished and entirely rebuilt with apron and airside works.
As a global resources company, Rio Tinto operates to its own rigorous engineering standards, built for the demands of remote, high-consequence mining infrastructure. Every element had to be specified and priced to those standards, not to a generic benchmark.
The SNZ approach
- ▸Full hydraulic estimate from all architectural and hydraulic drawings
- ▸Rio Tinto proprietary pipe and fitting specifications applied to every line item
- ▸All six systems individually scoped: fire, hot and cold water, stormwater, trade waste, sewer pump stations and sewer treatment
- ▸Wastewater treatment plant priced in full: 6 septic tanks at 20.7KL each plus 3 effluent holding tanks at 25KL each
- ▸Approximately 500m of sewer rising main fully measured including pump station requirements
- ▸Remote freight, craneage and logistics costed into every line
- ▸Full independent review before delivery to the contractor
The outcome
- ✓Complete off-grid hydraulic estimate delivered, all systems, all Rio Tinto specifications, nothing missed
- ✓Proprietary specification compliance priced across every pipe, valve, fitting and system
- ✓Remote site logistics accurately costed, including freight, craneage and supply chain
- ✓WWTP and wastewater treatment fully scoped, an area frequently underestimated
- ✓Contractor received a complete, submission-ready airport hydraulic estimate built for a remote mining environment
Woolworths Belmont North
Large format retail · corporate hydraulic standards
National retail · Belmont North NSW
The challenge
National retail infrastructure for Woolworths Group operates under strict corporate hydraulic standards, AS/NZS codes and tight programme requirements. Woolworths has non-negotiable specifications that must be met precisely.
The complexity of large format retail hydraulics, including commercial kitchen drainage, grease management, fire suppression interfaces, cold room drainage and customer amenities, requires a level of detail generalist estimates rarely reach.
The SNZ approach
- ▸Full PlanSwift takeoff from Woolworths corporate drawings and hydraulic specifications
- ▸Corporate compliance requirements built into pricing, no assumptions made
- ▸Commercial kitchen drainage, grease arrestors and cold room drainage individually priced
- ▸All work verified against Woolworths Group hydraulic standards before delivery
- ▸Delivered within the retail programme timeline
The outcome
- ✓Full hydraulic package delivered on time within the retail construction programme
- ✓Every item priced to Woolworths Group hydraulic standard
- ✓Scope gaps identified in preliminary estimates, protecting the contractor from underpricing
- ✓Estimate accuracy confirmed through construction
UNSW G25 Building
12 storeys · research & academic · laboratory drainage
Tertiary education · UNSW Kensington, Sydney NSW
The challenge
University-grade hydraulic systems operate under exacting AS/NZS compliance requirements, BCA standards and UNSW-specific design guidelines that go significantly beyond standard commercial specifications.
A 12-storey research and academic building at UNSW Kensington involves complex laboratory drainage, specialist cold and hot water systems, fire suppression interfaces and high-use amenity hydraulics, each of which prices differently.
The SNZ approach
- ▸Full PlanSwift takeoff across all 12 levels from hydraulic and architectural drawings
- ▸AS/NZS and BCA compliance requirements priced at every line item
- ▸Laboratory drainage and specialist systems individually priced
- ▸UNSW design guidelines incorporated into all pricing decisions
- ▸Full independent review before delivery
The outcome
- ✓Full 12-storey hydraulic package delivered on time within the university programme
- ✓Full AS/NZS and BCA compliance verified across every system
- ✓Specialist laboratory drainage correctly scoped and priced, an area commonly missed
- ✓Estimate precision confirmed as design developed through construction documentation
