Local Knowledge

Wollongong is defined by the Illawarra escarpment, with many suburbs built on steep, sloping blocks. Accurate contours matter here for retaining wall design, stormwater and assessing landslip risk on hillside properties.

Split-level houses are common on these blocks, and each level has to be picked up separately so an addition ties in at the right height instead of sitting a step above or below.

We work throughout North Wollongong, West Wollongong, Coniston and the wider Illawarra.

Council Requirements

Wollongong City Council places strong emphasis on accurate contour data for sloping sites, particularly in escarpment suburbs subject to landslip risk. Detail surveys should capture close contour intervals and show existing retaining structures and drainage clearly.

Property Types

Sloping escarpment blocks, beachside homes, split-level houses, hillside developments.

FAQs

Do I need a geotechnical report as well?
On escarpment blocks, often yes, and the geotechnical engineer works from your contour survey.

How does a detail survey help with view sharing?
View loss is assessed from levels and existing structures, so accurate data protects you in both directions.

What about beachside homes?
Coastal hazard controls apply, and they are assessed against AHD levels, so the survey needs to be current rather than an old plan redrawn.

How long does a sloping block take?
Longer than a flat one. More set-ups are needed to see the whole site, which we allow for in the quote rather than adding later.
