Obviously this is going to be hugely dependent on the job but here is a ballpark:
- Say 500+GST per inspection on average (travel time, mileage, inspection time, memo time, maybe a phone call or two)
- If we are doing a full house then there will be an excavation inspection (subgrade - by us or geotech), foundation pre pour, a preline inspection and maybe a pre-stop to check bracing. So min 4 inspects say $2k + GST, allow for inevitable phone calls etc through the project, maybe $2.5k+GST against a design fee of perhaps double that (5k+GST)
However, that's for a relatively low complexity engineered house (not a basic house, but not a fully architectural monstrosity)
Our involvement is dependent on the builder's sequencing - if the builder needs to stage their foundation pours, we will be coming back multiple times
Houses on hills need a lot of inspections as you end up with excavation + foundation pre pour + block pre pour for every stage of the site works - which could be 5+ stages sometimes!
I've just completed a mid complexity architectural house on the hill (maybe a 7/10 complexity) and the design fee was ~20k+GST and construction fees were ~7k+GST
I completed a very complex house (9+/10 complexity) on the hill last year with 30 inspection records
Not every one was a site visit (some times it's just documenting a design change etc) but I think we had 22-24 site visits on that job at a lot more than $500+GST each
Rarely would this be fixed fee: it's dependent on too many factors outside of our control (build sequencing, contractor quality, weather, design changes, human factors e.g. builder forgets something)
