ADVANCED CONSTRUCTION TECHNIQUES FOR SKYSCRAPER CONSTRUCTION

PRE-ENGINEERED BUILDING SYSTEM Pre-engineered building system consists of 7 main components made of superior concrete.This is a FAST and EASY technique for construction of any permanent building type. A single unit of any size/type can be erected within 7 days. The UDG building systems is launched after intense research and development by team comprising leading architects and engineers. Our system can be easily constructed at a job site resulting in dramatic time savings as well as eliminating the need for machinery.

PRE-ENGINEERED BUILDING SYSTEM Specially designed components based on interlocking principle are used, which offers: QUALITY: Components are manufactured out of superior grade concrete. ECONOMY: It offers 30% savings over traditional technology. SPEED: It is 10 times faster than traditional method of construction.

COMPONENT #1 FOOTINGThe function of footing is to distribute load from Column to the Foundation Soil below. For distribution of load on greater area of soil, wider slab is provided beyond the area required for supporting the load carrying components above it. For optimizing the weight without compromising for strength, concrete ribs are provided on thin concrete slab, similar to a bearing plate for supporting a steel column. Evolution of peculiar form for the footing is a result of search of optimistic structural solution. The component is adequately reinforced to keep the bending and shear stresses within permissible limits.

FOOTING: TYPE A AND TYPE B

COMPONENT #2 PEDESTALPedestal transmits load from column to the footing. It is shaped to occupy the space between the existing ground level and footing level. It is kept hollow by removing surplus concrete to reduce its weight. It is anchored adequately to both upper and lower elements to prevent segregation due to soil movement.

COMPONENT #2 PEDESTAL

COMPONENT #3 CAPITAL: TYPE A AND TYPE BFor flexibility of connection of column units with Joists, Tie-beams etc. a connector unit is designed with a central core matching the column section and projections in one to four directions to receive other elements in the desired direction. The seats of a connector receive high concentrated loads from these units; hence these are shaped and designed with special considerations for receiving these elements as well as heir fasteners.

COMPONENT #3 CAPITAL: TYPE A AND TYPE B

COMPONENT #4 TIE-BEAMUnlike the joists which are loaded transversely by the floor slabs, Tie-Beams provide adequate tying of the structure at different levels. These are similar to Plinth-band, Lintel-band and Slab-band which are obligatory for masonry construction in different seismic zones.The hollow H -Shape of the tie beam make reinforcement bars pass through the same, which are anchored in the column units, and finally embedded in cement mortar.

COMPONENT #4 TIE-BEAM

COMPONENT #5 WALL PANEL: TYPE A AND TYPE BHollow wall units are not merely the conventional hollow blocks used in construction. These are designed with keys for getting proper sliding and fitting in the column units to prevent its dislocation during seismic movement. The total width of these units are confined to 150 mm for making a wall without any projection or offset with the other units of the system making the houses more elegant and maintenance-free.

COMPONENT #5 WALL PANEL: TYPE A AND TYPE BFor an optimum design the wall unit, its thickness is reduced to merely 20 mm, which has been made possible by use of high strength concrete. This gives greater durability and resistance to moisture penetration. Due to its hollow configuration the blocks afford greater heat and sound insulation which is a very important consideration in construction of economical housing.

COMPONENT #5 WALL PANEL: TYPE A AND TYPE B

COMPONENT #6 JOIST (BEAM)The function of a joist is to support the slab units and transfer the live loads and dead loads to the column units. For minimizing the self load of these units, web is made as thin as possible to give it a shape of a T . The portions of Joists near ends are specially designed for suitability of connection with the Corbel unit. Similarly at the top of the unit a special fastening strip is provided for connection of slab units to prevent segregation during seismic activities. Joists are manufactured in different lengths to offer flexibility in selecting the room dimensions.

COMPONENT #6 JOIST (BEAM)

COMPONENT #7 SLAB PANELThese units are supported on joists and cover the space of the room. For ease of construction, these are manufactured in width of 250 mm and joints are filled with non shrink polymer grout. Finally a layer of in-situ IPS with chicken-mesh with integrated water proofing compound is laid for sealing the joints and serving as backing for desired flooring. Slab units are adequately reinforced to avoid cracking.

COMPONENT #7 SLAB PANEL

AGREEMENT WITH BUILDING CODESAs per the NBC (National Building Code), the components have been developed to meet the specified nominal lengths. Each element of the precast kit is designed to withstand the loads specified by BIS (Bureau of Indian Standards).In addition to normal loads, the elements have been designed to withstand stresses during handling, transport and construction. The structure as a whole is checked for stability and strength during wind and seismic forces also. The concept considers modular planning, component sizes, joints, manufacturing, storage, transportation, and construction.It can redesign to comply with a given country's building code and specific needs.

ARCHITECTURAL FEATURESGood architectural design not only satisfies the needs (Physical and Psychological) of the user, but also is made easily affordable to him. Design should also take good care of influence of social order and cultural conditions at given point in time. Simultaneously it should also accommodate the Technological advancement. With these parameters and a set of other relevant issues, this concept of a prefab house was evolved. All the aspects were incorporated right at the design inception stage so that the entire building or complex of building built within system is conceived in totality-in terms of architectural expression, structural design, function, etc.

BUILDING DESIGN Building design meets or exceeds following specifications for architectural excellence: Economy in cost, efficiency in design, reduction in time. Aesthetically satisfying designs. Possible to break monotony and unappealing appearance. In group housing, each unit can be designed to give individual character, to affect better performance and greater user satisfaction. Satisfies user's primary needs and aspirations of users. Can be constructed anywhere, can perform equally in any geographical location and any climatic zones.

BUILDING DESIGN Through endless possibilities in designs, there is scope for user's inception. Possible to introduce finishes and architectural treatment for the creations of a particular architectural character in individual building and in group of buildings by use of color, textures, recesses etc. Building components can be treated as architectural elements and various treatments can be given for better overall performance and appearance. Exterior-Interior can be natural cement finish; color can be light gray or painted as per user's specifications with cement paint.

COMPONENTS OF PRE-ENGINEERED SYSTEMSComponents of pre-engineered Building Systems are designed to give:Clear span of 1.8 m to 6.3 m. Larger span is possible with this system using steel components Interior height 2.7m to 3.3m. Higher interior heights can be catered on special jobs. Ground and one storey structures can be built Plinth height of 300/450/600mm.

QUALITY, ECONOMY AND SPEED COMPARISONDescription

FEATURESAny type and size of building is possible.Extension as well as expansion is simple. Ground plus one floor structure is possible.The components are light weight, can be easily handled. No special machinery, like crane, is required for its construction.No Skilled labour is required and cost of technical supervision is minimized.Minimum Water and Mortar are required for component assembly, which allows them to be laid faster and adaptable in water scarcity areas.
