BPM307 TMA02 (Tutor-Marked Assignment Two) SUSS: July 2024 Presentation – Cost Planning and Estimation, Singapore

Question 1

Prepare the preliminary cost plan for your new industrial project located at Changi East and is on reclaimed land.

• Land size 3.5 ha
•  GFA 55,000m2
•  Multi-storey carpark 5,000m2
• Concept design
•  Green Mark – Platinum Positive Energy certification. To achieve positive energy industrial building, 3,000 sq m solar panel with 20% of the electricity generated to be returned to the national grid. Indicative cost: Solar panel – supply and install $500/m2 including structural support.
• External works – Incremental cost due to larger land size is $80/m2 site area.

Below is the building design and cost plan for a completed industrial project awarded in 2018, with total GFA of 35,000 m2 and with land size of 0.5 ha. The project is certified Green Mark Platinum

Table Q1 – Cost Plan for Past Project.

References:
• Appendix 1 – Cost references of Singapore Construction Cost Data.
• Appendix 2 – BCA Tender Price Index
• Appendix 3 – Schedule of rate

Prepare the elemental cost plan with the elemental rates and elemental costs for the proposed development.

Derive the project unit rates per m2 for the estimated construction cost.

Question 2

(a) Based on the data in Table Q2, estimate the unit rate for reinforced green concrete of Grade 40 ($/m3 ).

(b) Briefly explain to the client how the use of eco green concrete or other sustainable materials and technologies can benefit the project.

(c) Based on the materials price indices published by BCA, discuss the implications on construction materials.

Question 3

Architect issued instruction to replace cement sand screed flooring to homogenous floor tile to a 10 m x 20 m room.

Contract specifications.

Homogeneous Floor Tiles

12 mm thick homogeneous floor tile on 38 mm thick cement sand screed backing.

a) Prime cost supply rate $30/m2

• Wastage 5% (tiles)
• Contract profit and attendance on PC rates is 10% (a) Prepare the variation cost estimate for the changes instructed by the Architect using Appendix 4 – Variation Template.

(b) Based on the variation in Q3(a), build up the composite rate for the 200 mm thick reinforced concrete suspended floor (rebar ratio 180kg/m3 ) including the finishes
