3 THE AWARDS The BCA Construction Productivity Awards - Projects recognise the contribution of project teams towards achieving productivity enhancement in their construction development projects from the design to the end of construction. The Awards aim to: (i) Encourage designers to come up with labour-efficient designs; (ii) Encourage project teams to adopt labour-efficient construction methods; and (iii) Recognise project teams for their excellent project planning and coordination in enhancing productivity. Awards will be given out in nine categories: - [1] Residential Landed Buildings Category [2] [3] Residential Non-landed Buildings Category (for projects with GFA < 25,000m 2 ) Residential Non-landed Buildings Category (for projects with GFA 25,000m 2 ) [4] Commercial and Office Buildings Category [5] Institutional Buildings Category [6] Industrial Buildings Category [7] Mixed Development Buildings Category [8] Additions & Alterations / Upgrading Buildings Category [9] Civil Engineering Projects Category For additions & alterations / upgrading projects, nominations will only be accepted if new floor area is added to the existing buildings. Winning projects will either receive a Platinum Award or a Gold Award. The Awards are not competitive but standard based. An Award will only be conferred if a suitable entry is received. Several Awards may be conferred in each category. A Gold Award will be awarded to a project that has adopted good buildable design qualities and construction methods that reflect ease of construction. A Platinum Award will only be conferred to a project that has displayed exemplary buildable design features and adopted advanced construction technologies that have led to commendable productivity outcome. 3

23 Description of work: Conventional Method Description of work: New Improved Method Assumptions made: Assumptions made: Manpower required (no. of workers) = Time required (manhours) = Work done (m, m 2 or m 3 ) = Manpower required (no. of workers) = Time required (manhours) = Work done (m, m 2 or m 3 ) = Productivity (m, m 2 or m 3 per manhour) = Productivity (m, m 2 or m 3 per manhour) = Savings: No of workers = Time = Productivity improvement (%) = Material Cost = Labour Cost = Prelim Cost = Total Cost = Material Cost = Labour Cost = Prelim Cost = Total Cost = Cost Difference = 23

24 Description of how the new improved method contributes to good finishing quality and higher CONQUAS score: 24

25 Example on filling up the Productivity Improvement Calculation Worksheet: Conventional Method New Improved Method Description of work: Erecting internal wall partition using plastered brick wall Description of work: Erecting internal wall partition using drywall Assumptions made: (a) Use of 100mm thick brick wall (b) Floor to floor height 3.0m (c) Work include erection of bricks and plastering Assumptions made: (a) Use of 19mm thick gypsum board with a panel width of about 1200mm (b) Floor to floor height 3.0m (c) Work include setting up of frame, installation of acoustic insulation wool stuffing and gypsum board Manpower required (no. of workers) = 3 Time required (manhours) = 4.0 Work done (m, m 2 or m 3 ) = m 2 Manpower required (no. of workers) = 2 Time required (manhours) = 1.7 Work done (m, m 2 or m 3 ) = m 2 Productivity (m, m 2 or m 3 per manhour) = m 2 / 4.0 manhour = = 0.88 m 2 /manhour Productivity (m, m 2 or m 3 per manhour) = m 2 / 1.7 manhour = 3.11 m 2 /manhour Savings: No of workers = 1 Time = ( ) = 2.3 manhour Productivity improvement (%) = [( )/ 0.88] X 100% = 253% 25

26 Material Cost = A 1 Labour Cost = A 2 Prelim Cost = A 3 Material Cost = B 1 Labour Cost = B 2 Prelim Cost = B 3 Total Cost = A Total Total Cost = B Total Cost Difference = [(B Total - A Total )/ A Total ] X100% Description of how the new improved method contributes to good finishing quality and higher CONQUAS score: The dry wall has better finishing quality. Its smooth and clean surface is ready to receive the final finish and has minimum defects as compared to brick wall. In general, the drywall results in a higher internal wall score in CONQUAS of about 15 points as compared to brick wall. 26
