Occupancy
The project is in construction stage.
Parking
Provision has been made for adequate space for parking in the project. Parking will be provided in the form of surface parking and basement parking. Proper entry and exit system for vehicles will be developed to avoid traffic congestion in the area. Entry route and exit route to the complex will be separate.
Water Supply
Source of fresh water in operation phase will be the municipal supply water supplemented by existing 2 (two) no. of bore wells registered in Central Ground Water Authority. The water will be first disinfected and then supplied. There is no requirement of fresh water for cooling. The water requirement for landscaping will also be met by the treated sewage from Common STP in DLF 5, Sector-43.
Sewage treatment
Sewage generated in the project will be treated up to tertiary level in existing Common Sewage Treatment Plant (STP) located in DLF5, Sector-43. The entire (100%) treated water from STP will be recycled/ reused for toilet flushing, cooling and horticulture in the project.
Electricity
Power requirement for the project in operation phase will be met from energy centre to be set-up at basement. Further there will be provisions of DG sets as power back-up incase of power failure. All the DG sets will be located at the basement in acoustically treated room.
Fire Safety
The building will be well equipped with all fire fighting equipments (i.e. fire water tanks, fire pumps, fire hydrants, sprinkler system, fire alarms, fire extinguishers, hose reels etc.) as required under the local fire norms.
Rain water harvesting:
The rainwater collected from the rooftop and other paved areas within the project area will be conveyed into the rainwater harvesting system consisting of Desilting chamber, Oil & grease separator and Recharge pit with bore well for recharge into the groundwater.
Disposal of municipal solid wastes:
Solidwastes generated will be segregated into biodegradable and non-biodegradable components and collected in separate bins. Both the biodegradable wastes and non-biodegradable/ recyclable wastes will be sold to authorized vendors.
