Smart build with BIM

Early engagement is key for BIM in IPD for sustaina ble and Smart Build

Early engagement of Stake holders with sustainable studies is key to Integrated Project Delivery that leads to efficiency and gains for smart build

Case Study 2 – Proposed Hospital Building at Lucknow

Project details:•No. of Beds: 1000•Multi-speciality Hospital•Built up area: 1.4 Million Sqft•No. of OT’s: 35

Project Challenges:•Energy Efficiency: Highly energy intensive building typology•Low temperature chilled water supply to maintain OT indoor conditions•Achieving Daylight & Views in interior spaces

Daylight Optimization

Case Study 2 – Proposed Hospital Building at Lucknow

Low Temperature Chilled Water:•Design Case-1, Conventional approach: Common chilled water plant for entire building•Design Case-2, IPD approach: Separate chilled water plant for OT’s and rest of the building

Capex:•Increased by 5% of total building cost
