NB: As noted elsewhere we don’t sell time.  The fees are derived from an upper fee limit of $5000 and then divided into 10 levels using a geometric series and rounded. The approximate hours based on Australian federal minimum rate, is provided as reference for labour cost ignoring operating cost of business.  Assuming a business has near equivalent operating costs to a person, than minimum charge out rate is twice the federal minimum rate (eg. $35.40): the upper limits of hours are thus only viable if someone else provides all the required resources.

The estimated typical hours are based on hourly rates which varies from $55/hour to $110/hour (inc. GST): the variation is to account for complexity and risk, and the type of work involved. The hours overlap because two projects of equal duration will have differences in complexity, risk and type of work involved.  For example two projects of equal duration will have different fees if one project has more drafting time, whilst the other has more calculation (“engineering”) time: assuming drafting costs less than “engineering”. Based on distribution of time, an average rate can be determined for the project. Two projects of equal duration and only involving calculation, will have different fees based on complexity and risk. With respect to risk, we assume most of our projects are relatively low risk, with the projects being established technologies for which there is an established body of scientific knowledge which can be used to ensure fitness-for-function. So complexity is the major determinant of difference: for example a flat roof carport is less complex than a gable roof carport. A free standing carport is less complex than an attached carport: for the attached carport also need to assess the house structure. The house structure is not accessible and largely unknown, and so the risk is higher.

Projects are pursued for fixed fee, and hours are irrelevant {well relevant, if time is too long, then won’t pursue similar projects again for similar fee.}.
