What we build
One contractor for the whole complex.
Godowns, platforms, roads, walls and drains, delivered together. Point at a number on the plan to see what it is.
How we build
A godown, built in the order a site follows.
Typical 5,000 MT godown, three bays at the gable end. Truss shape and roof pitch are assumed, and so are these sizes in mm: columns 400 × 400, column footings 1,200 square, lintel band and tie beam 150 deep.
- Setting out Column lines at 4,650 centres and a 21,800 span are marked on the ground. The first inspection signs off the layout before any digging.
- Foundations Column pits go down 1,300 onto a lean concrete bed. The soil is treated against termites before anything is built on it.
- Plinth The floor is raised 800 above the ground: level with a truck bed, and clear of flood water. The fill goes in thin layers, rammed, then flooded for a day.
- Walls to lintel Concrete columns and thick brick walls rise together to door height, where a concrete band ties the wall.
- Walls to tie beam Every panel gets a top ventilator. A tie beam locks the column heads, and bolts are cast in to hold the roof down.
- Roof steel Tubular trusses are lifted onto the columns, then purlins and wind ties. The end wall carries the purlins itself, so it needs no truss.
- Sheeting, doors, floor The roof goes on first so the floor can be laid dry beneath it. Steel doors hang on the outer face of the wall.
- Completion Plinth protection and the concrete road finish the job. The last inspection asks one question: is it fit for occupation?
Engineering
Why the roof is bolted down.
When a gale builds, every member of the roof truss trades tension for compression. You are the wind: move across the godown and watch it happen.
Details
The rest of the complex.
Walls, roads and drains get the same care as the godown they serve.
Roads and bridges
Go ahead. Load it.Built for the load that crosses it.
We build roads and bridges too. Your pointer is a standard highway loading train. This page solves the bridge as you move: reactions, shear, bending moment, deflection.
