Civil Engineering & Estimation
Ten packages. No overlap. True engineering precision.
We quantify, model, and cost civil packages with exactness — helping contractors win tenders with confidence and protect project margins from ground break to handover.
Why It Matters
Civil margins are won or lost in the ground.
A missed pit, incorrect rock volume, or miscalculated earthworks balance can erase a subcontractor’s profit margin. SUCHAN bridges the gap between design engineering and contractor commercial reality.
We work directly from tender drawings, IFC models, and soil reports to generate clear, structured take-offs and pricing schedules ready for submission.
Civil 3D Earthworks
TIN surface modelling comparing natural surface (NS) to subgrade and finished design levels to determine cut, fill, bulking, and spoil volumes.
AutoCAD 2D Markups
Colour-coded visual verification overlays demonstrating every linear meter of pipe, trench, pavement, kerb, and retaining wall.
First Principles Rates
Detailed rate buildups factoring labour crews, plant hire, fuel, material supply, cartage, and site-specific productivity factors.
Fast Turnaround
Typical 40-hour response window on critical civil packages, supported by our dual-timezone engineering capacity.
The 10 Packages
Ten packages. No overlap.
These are the actual civil work packages we quantify, estimate, model, and support.
Site Preliminaries
Site establishment, access planning, temporary fencing, signage, safety setups, and all initial requirements that define how the project begins.
Environmental Controls
Silt fencing, sediment basins, erosion protection, tree protection zones, and temporary drainage systems to meet ACT/NSW environmental compliance.
Bulk Excavation
Cut/fill volumes, site balancing, earthworks shaping, and excavation staging — calculated using engineering grade modelling.
Shoring & Retention Systems
Bored piers, soldier piles, shotcrete walls, temporary retention, and structural/geotechnical support required for safe excavation.
Detailed Excavation
Precise excavation for footings, trenches, pits, retaining walls, slabs, and all structural elements — measured directly from drawings.
Hydraulic Works
Stormwater lines, pits, aquacomb pods, pump pads, downpipes, inspection points, and all civil hydraulic components.
Service Trenches
Electrical, communications, water, gas, sewer, and stormwater trenches — including bedding, backfill, compaction, and reinstatement.
FRP (Formwork, Reinforcement & Concrete)
Formwork areas, reinforcement weights, concrete volumes, edge beams, slabs, footings, retaining walls — quantified with engineering precision.
External Civil Works
Pavements, kerbs, footpaths, driveways, ramps, bollards, external slabs, and all external civil elements.
Landscaping
Soft and hard landscaping including turf, planting, mulching, edging, paving, irrigation, retaining walls, and external finishes.
