ABSTRACT
The state-of-practice method to produce formal,
good-quality work instructions for a particular
construction activity consists in a person or group:
(i) selecting the proper design information from the
project’s set of construction drawings or product
models; (ii) establishing the best practice (con-
struction steps and equipment and tools needed)
to perform the respective construction activity;
and finally, (iii) deciding on a format to commu-
nicate this information to the laborers and putting
the selected design and construction information
into that format. This method presents three main
challenges:
− Effort: from our observations, it takes between 1
and 2 hours to produce a good work instruction.
− Error proneness: producing good instructions
