14. PROPOSAL 1 UPVC and CPVC types of pipes are capable of fulfilling all the requirements and achieve desired objectives. DEVELOPMENT PHASE COST DATA PIPING (Supply Water) SR 9362.5 Savings in Initial Cost SR 15025.05 – 76 % FOR THE PROPOSED DESIGN

15. DEVELOPMENT PHASE PROPOSAL 2 – 2 OVERHEAD TANKS Original Design: 2 Overhead tanks made of concrete with steel structure are to be constructed on the roof of the villa. Proposed Design: 2 Overhead tanks made of PVC can be installed which will give better performance and costs very less. Discussion: Concrete tanks do not restrict heat and it takes more time to construct, whereas PVC tanks are readymade, weather proof and takes very less time to install.
