What we measure
We don’t estimate generic civil works or structural concrete. We stick strictly to what we know best: high-impact interior fitout and strip-out trades. We deliver accurate quantities across these core scopes:
Partitions & Drylining
From standard acoustic office dividing walls to complex fire-rated drywall configurations, we measure every wall run down to the linear meter.
Ceilings & Bulkheads
Accurate square-meter takeoffs for standard suspended tile grids, concealed plasterboard ceilings, and custom architectural feature bulkheads.
Doors, Frames & Hardware
Complete, itemized door schedules detailing timber or aluminum frames, leaves, glass inserts, and all specified ironmongery or hardware sets.
Demolition & Strip-Outs
Clear quantification of structural layout changes, slab grinding areas, and partition/ceiling removal grids so you can scope your disposal accurately.
Flooring & Finishes
Precise square-meter takeoffs for carpet tiles, vinyl sheet, engineered timber, and required floor preparation treatments.
Miscellaneous & General Extras
We catch the easily missed details that eat into margins, including skirting boards, acoustic insulation batts, and final builders' cleans.
