FOOTING: TYPE A AND TYPE B . • It is kept hollow by removing surplus concrete to reduce its weight. . • It is shaped to occupy the space between the existing ground level and footing level. • It is anchored adequately to both upper and lower elements to prevent segregation due to soil movement.COMPONENT #2 PEDESTAL • Pedestal transmits load from column to the footing. COMPONENT #2 PEDESTAL . COMPONENT #3 CAPITAL: TYPE A AND TYPE B • For flexibility of connection of column units with Joists. • 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. Tiebeams 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. COMPONENT #3 CAPITAL: TYPE A AND TYPE B . . which are anchored in the column units. 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. and finally embedded in cement mortar. • These are similar to Plinth-band. Tie-Beams provide adequate tying of the structure at different levels.COMPONENT #4 TIE-BEAM • Unlike the joists which are loaded transversely by the floor slabs. COMPONENT #4 TIE-BEAM . • 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 B • Hollow 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. . . • Due to its hollow configuration the blocks afford greater heat and sound insulation which is a very important consideration in construction of economical housing. which has been made possible by use of high strength concrete.COMPONENT #5 WALL PANEL: TYPE A AND TYPE B • For an optimum design the wall unit. • This gives greater durability and resistance to moisture penetration. its thickness is reduced to merely 20 mm. COMPONENT #5 WALL PANEL: TYPE A AND TYPE B . web is made as thin as possible to give it a shape of a T . • Similarly at the top of the unit a special fastening strip is provided for connection of slab units to prevent segregation during seismic activities.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. • Joists are manufactured in different lengths to offer flexibility in selecting the room dimensions. . • The portions of Joists near ends are specially designed for suitability of connection with the Corbel unit. COMPONENT #6 JOIST (BEAM) . • For ease of construction. • Slab units are adequately reinforced to avoid cracking. these are manufactured in width of 250 mm and joints are filled with non shrink polymer grout.COMPONENT #7 SLAB PANEL • These units are supported on joists and cover the space of the room. • 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. . COMPONENT #7 SLAB PANEL . • In addition to normal loads. . transport and construction. manufacturing.AGREEMENT WITH BUILDING CODES • As per the NBC (National Building Code). the elements have been designed to withstand stresses during handling. and construction. • The structure as a whole is checked for stability and strength during wind and seismic forces also. the components have been developed to meet the specified nominal lengths. transportation. • It can redesign to comply with a given country's building code and specific needs. storage. joints. component sizes. • The concept considers modular planning. • Each element of the precast kit is designed to withstand the loads specified by BIS (Bureau of Indian Standards). With these parameters and a set of other relevant issues. but also is made easily affordable to him. etc. • 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. this concept of a prefab house was evolved.ARCHITECTURAL FEATURES • Good architectural design not only satisfies the needs (Physical and Psychological) of the user. function. • 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. structural design. reduction in time.BUILDING DESIGN • Building design meets or exceeds following specifications for architectural excellence: • Economy in cost. to affect better performance and greater user satisfaction. each unit can be designed to give individual character. • Possible to break monotony and unappealing appearance. • Can be constructed anywhere. can perform equally in any geographical location and any climatic zones. . • In group housing. • Aesthetically satisfying designs. efficiency in design. • Satisfies user's primary needs and aspirations of users. there is scope for user's inception. textures. color can be light gray or painted as per user's specifications with cement paint. • 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. • Building components can be treated as architectural elements and various treatments can be given for better overall performance and appearance. recesses etc.BUILDING DESIGN • Through endless possibilities in designs. . • Exterior-Interior can be natural cement finish. Ground and one storey structures can be built • Plinth height of 300/450/600mm.3 m. Larger span is possible with this system using steel components • Interior height 2. .8 m to 6.3m.7m to 3.COMPONENTS OF PRE-ENGINEERED SYSTEMS • Components of pre-engineered Building Systems are designed to give: • Clear span of 1.
