Investigation for Finding out Difficulties in Construction of High Rise Building & Suggest Remedial Measures to Expedite the Execution Process of Activities

Abstract

High-rise buildings are designed with all modern & luxuries amenities for giving comfort & happy life style to buyers. The service lines & setup of infrastructure required for providing amenities are normally provided in basements. Such like, parking, CCTV Control room, Drivers room, Society office, Rooms for servants, Toilets for Drivers, Servants & maintenance staffs. Electrical Transformers, UG Tank, Fire fighting tanks, STP etc. Therefore basement of high rise building is very important part of building. Developer, Architects & Engineers are very much conscious about construction activity involved in basement as it is underground structure. In basements activities especial care to be taken because activities involved such like waterproofing, raft, footings & retaining wall includes. Membrane coatings for waterproofing of RCC elements are presently getting used in most of high-rise buildings. To stop entry of water in basements, waterproofing is needed to get done to horizontal & vertical plane that is, to retaining wall in vertical plane & below raft in horizontal plane. Due to rounded section of shore piles in vertical plane level surface to fix waterproofing membrane is not possible to get. So to make level surface plume concrete wall (PCW) is required to construct. It is observed during case study that, construction of plume concrete wall (PCW) required for fixing waterproofing membrane is time consuming activity. The object of this study is to expedite construction activity of plume concrete walls by finding out another option to plume concrete wall. Also to suggest new material of constructing PCW & reduce PCW construction duration & cost. On basses of case study at project site, Second option of "Skin wall" Construction instead of "Plume concrete wall" is suggested.
