Contour and Detail Surveys in Sydney CBD

Contour and detail surveys across the Sydney CBD, where sites are tight, neighbours are attached and every level has to be measured.

Local Knowledge

The CBD is largely built up with little natural terrain variation, but level changes between streets, basement interfaces and existing structures still need careful capture. Party walls and shared boundaries with adjoining buildings are common and demand precise detail.

Access is the practical constraint. Tenancies, basements and street frontages often have to be surveyed around trading hours, and we plan the visit so it does not stop the business.

We work throughout Surry Hills, Pyrmont, Darlinghurst and the wider inner city.

Council Requirements

City of Sydney Council requires a current detail and level survey for most development applications, particularly for heritage-listed properties and sites in conservation areas. Plans should reference Australian Height Datum and show existing structures and easements clearly.

Heritage and conservation-area proposals get the closest look, with existing fabric and levels shown as they are.

Property Types

Heritage terraces, commercial towers, mixed-use developments, apartment buildings, retail premises.

FAQs

How do party walls affect the survey?
They are the boundary in practice, so we record the wall, its thickness where we can see it, and the structures either side.

Do underground services need locating?
For most commercial work, yes, and that is a separate underground service location job we can run alongside the survey.

Why do AHD levels matter for a street-level shopfront?
Because footpath levels, accessible entry and drainage all have to work together, and they are designed off a common datum.

Can you survey without closing the shop?
Usually. We work around trading hours and keep the disruption to a short window, which we agree with you before we come.
