FLOORS
PRECAST SLABS
• Advantages • Fireproof per se
• Better quality
• No need temporary support
• (Hollowcore cheaper than composite?)
• Disadvantages • Long fabrication period?
• Best suited for structures that are totally regular and repetitive in nature
• Lifting equipment
CONCRETE SLABS
• Advantages
• Faster (up to 400m2/day?)
• Flexible to changes in scope
• Constructability
• Disadvantages
• Fireproofing required?
• Secondary beams

EMPHASIS ON COORDINATION ISSUES
• Thermal Insulation (SE with MEP)
• Green roof insulation and access (All with MEP)
• Services Shaft positioning (All with MEP)
• Floor footprint (SE with MEP)
• Skywalk

BUILDING SERVICES PROPOSAL
HVAC system embedded with BMS. Type: Hybrid (Mechanical plus Natural ventilation)
• Client demands intelligent/efficient & sustainable building.
• Natural ventilation not sufficient
• Only Mechanical too expensive.
• Building divided into many compartments/divisions, like communal and private areas.
