A factory building in Pune with an area of 3,64,380 sq ft accommodating three mezzanine floors and 2 no’s of 45MT crane was analysed and designed using STAADPro software. It has a maximum bay spacing of 12m with an expansion joint with varying height after the expansion joint. The structure also houses office and rest room areas inside the building. The factory building consists of an A type roof lattice truss with lattice trusses spanning up to 35m in the longitudinal direction. Dead loads, Live loads, Wind loads, Seismic loads and Crane loads were followed as per Indian standard codes. The design was done using Indian standard codes and optimum sizes were acquired. The isolated and combined footings, pedestal and plinth beam were designed using in-house spreadsheets as per IS Codes.

Various structures such as the Footover bridge (5405 Sqft), Concourse (15578 Sqft), Skywalks (2319 Sqft & 2848 Sqft) and the forecourt canopy (26192 Sqft) were modelled, analysed and designed in STAADPro software. The Footover bridge, Concourse and skywalks are made of I-section beam girders with curved steel roof made of tube sections whereas the column are made of circular sections. The structures consist of a decking sheet and an RCC slab. The Footover bridge and Concourse have beam girders running at a span of approximately 28m. Additionally, steel staircases and lifts areas were designed. Dead, Live, Seismic and wind loads were considered and followed in accordance with the Indian codes and as per client specifications. All the structures were designed using Indian codes and standards. Anchor bolts and the structure connections were done using in-house spreadsheets as per Indian codes.

The compressor building for an air separation unit shed has an area of 13128 sq ft. Various pipes run through this building with the pipes being supported on goalposts and brackets which are in turn supported on the rafter and column members. Cable trays run throughout the periphery of the building. The building also houses seven 12T monorail cranes and a water tank on the roof of the building. The pipe, cable trays and monorail loads were also included in the dead load. Additionally, live loads, seismic and wind loads were considered as per client specification and Indian codes and standards. Moment frames are considered in both the directions as the building does not have ample area to provide bracings in the longitudinal direction. The building design, anchor bolt and other connection design was also done complying with Indian codes and standards.

This shipyard workshop building has an area of 25,442 sq ft and a clear height of 25m with an additional fascia for 3m. The structure is analysed and designed using STAADPro adhering to Indian codes and standards. The building accommodates two 25t cranes and the tandem action of those cranes were considered in design. Various load considerations including dead, live, wind and seismic loads and load combinations were considered as per the Indian codes. Notably, the structure was designed for seismic zone IV. The anchor bolts and connections were designed using in-house spreadsheets and complies with Indian codes and standards. Additionally, the fabrication drawing was issued.

The metro depot stations comprises of stabling and internal cleaning shed (265858 Sq.ft), Inspection bay (49496 Sq.ft), Repair and pit wheel lathe shed (80054 Sq.ft) and ETU shed (9684 Sq.ft). A preliminary estimation was done for the various buildings and then a detailed analysis and design for each building was performed. Various load considerations including dead, live, wind, seismic loads, temperature loads and load combinations were considered as per the client requirements and the Indian codes and standards. The crane loads for the repair bay and pit wheel lathe (2no’s of 15MT and 2 no’s of 3.2 MT), Inspection bay (2 no’s of 1.5MT) and ETU (1 no of 5MT) were considered for the loads. The main frame is considered as a moment frame and bracings are provided in the longitudinal direction to provide stability. The building design, anchor bolt and other connection design was also done complying with Indian codes and standards. The fabrication drawings for all the buildings were also issued.
