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 industry some 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.

Proper use of jointing tape as per approved method statement and material submission. Jointing tape is used for reinforcement of plasterboard recessed joints, internal angles, surface fractures and repairs to internal walls. Use of internal corner taping tool for internal cor ner ner..
Mix proportion to be in accordance to the manufacturer’s manufacturer’ s instruction. Ensure that compound is used within the stipulated working time as recommended by the supplier, approved method statement and material. Mixing joint compound in clean buckets reduces probability of lumps forming, scratches and hard working material. Flush and clean compounds from equipment, and brush before the setting action takes place. Immersion of equipment in water will not prevent hardening of the compound.
