Abstract
Generative design has been applied to facilitate architectural exploration and augment designers' ability to consider building profits. However, the take-up of generative design instruments is slow due to the lack of considering practical needs. This paper reports a novel generative design methodology that meets the practical needs of profit-aware morphology for high-rise buildings. It follows a generation–evaluation–optimization workflow but is enriched with a novel shape generator; an evaluator estimating construction cost and selling revenue; and an optimizer using genetic algorithms. The methodology is prototyped in Grasshopper with Python programs embedded and then tested in two real cases in Hong Kong. We find that the methodology is effective in generating complex yet plausible morphologies for high-rises, evaluating their costs and revenues, and deriving profit-optimal buildings. This research contributes to the growing literature on generative design and could lead to a practical design tool that bridges designers and surveying professions.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
