FOREWORD
The Building and Construction Authority’s (BCA) Construction Quality Assessment System(CONQUAS) has been widely adopted as the de facto national yardstick for measuring the
Mark (QM) Scheme was launched in 2002 to promote a higher consistency in workmanship
standards for residential developments. Besides setting standards and measuring the level
of workmanship through CONQUAS and QM, BCA has developed a series of publications of
Good Industry Practices Guide for different trades.
This “Good Industry Practices – Drywall Internal Partition” is part of the CONQUAS
Enhancement Series on Good Industry Practices. A noticeable increase in the use of drywall has
been observed in the construction industry over the years. Drywall construction has emerged
without compromising its primary functionality as an internal wall. The use of drywall is also
encouraged and recognised under CONQUAS 8th edition. This guide shares with the industrysome of the good practices adopted by practitioners and contractors who consistently
associated with drywall internal partition and their corresponding remedies are highlighted.
With the tight manpower constraints faced by the industry, drywall construction is a highly
practical option.
with changing technology. To obtain more comprehensive information and guidance, readers
should seek advice from professional designers and material suppliers. We gratefully
acknowledge the contributions of the practitioners to this guide and trust that the industry will
from readers that may improve future editions of this guide.
