Constructability should be an important objective in all phases of a c
onstruction project, and designers play an important role in achieving
superior constructability. Most projects, however, do not receive con
structability input though prior research has demonstrated the benefit
s of such input. One reason for this lack of constructability input, w
e argue, is the lack of formal, explicit constructability knowledge ba
ses that link constructability issues to design decisions and that can
be made available on-line to interested parties. This paper describes
research that compiled and formalized constructability knowledge rela
ted to reinforced concrete structures. To ensure appropriate and speci
fic constructability input, we classified the knowledge by constructio
n methods and structural elements. To make this specific knowledge ava
ilable to designers at the right time during design development, we fu
rther divided it into the five groups: application heuristics, layout
knowledge, dimensioning knowledge, detailing knowledge, and exogenous
knowledge. This classification leads to conclusions regarding the abil
ity to collect and formalize this knowledge, and to make it readily av
ailable to designers to improve project performance.
