About Smart Architectural Estimates​

 

​

​

Smart Architectural Estimates was established in 2015, drawing on over 30 years of building experience. SmartAE provides construction cost estimating services to architects and building professionals across Australia, helping clients measure and record project quantities and costs. With deep experience across both commercial and domestic building, and a strong focus on detail and cost control, SmartAE is often brought into a project's design phase to advise on both budget and build-ability.

Preliminary Estimates

​

Used to test project feasibility early on. Often the estimate a builder gives an architect at design-development stage, to reassure the architect's client that design is tracking to budget. Available for Builders and Architects, covering New Builds, Additions, Alterations, Renovations and Commercial projects. Each estimate is individually measured using averaged industry rates (with some sub-category breakdowns). Essentially an expanded sqm-rate estimate adjusted for building style and quality. Being elemental, Preliminary Estimates don't specify features, finishes or fixtures, and represent a cost the project could be built for, not a guaranteed final figure.

Architectural Estimates

​

Prepared from design-development drawings (plan views and elevations required), fully measured, providing material, fitting and fixture quantities, this estimate style allows your clients to adjust their design to suit budget before committing further. Architectural Estimates use industry-average and builder-client rates rather than individual subcontractor quotes.

PC items and finishes are estimated at quality level rather than specific product/model pricing. Many components are priced as composites (e.g. footings priced as a lineal-metre rate covering excavation, reinforcement, concrete and labour) rather than split into materials and labour. Because the supplied documentation is usually insufficient to actually build from, this estimate is a budget guide only — quantities and rates may change once full tender documentation is complete.

This type of estimate may be supplied by our estimating partner, Smart Building Estimates.

Tender Estimates

​

Tender Estimates involve a full quantity take-off, with a comprehensive trade-by-trade cost breakdown in BOQ style, based on a review of drawings, engineering and specifications. Pricing uses averaged data for the client's location, with the option to substitute the client's own trade quotations or rates — typically actioned as a revision after initial delivery, at no extra charge. In-house labour is priced the same way a subcontractor would be, so labour allowances are clearly visible.

PC items can be standard allowances or client-supplied quoted prices.

This type of estimate may be supplied by our estimating partner, Smart Building Estimates.
