Our work
Overview
We build district, rural and urban roads for government departments and public sector undertakings, and we compete for this work through public tenders.
A road contract brings several kinds of work together: earthwork for the embankment, granular layers, a bituminous or concrete surface, culverts and drains where water crosses the road, and road furniture once the surface is down. We take a road through all of these stages, so the department deals with one contractor from survey to handover.
What the work covers
Most road contracts are one of these, or a mix of them along the length of the road.
A new road on a fresh alignment: clearing, earthwork and subgrade, the granular layers, the surface, and the drains and culverts that keep it dry.
Extra width or extra lanes on an existing road. The new strip is built up from the subgrade and joined to the old pavement, so the road carries traffic as one.
A new layer over a road that is wearing out. The old surface is repaired and levelled first, then the overlay is laid to the thickness in the design.
Kerbs, signs, road studs, crash barriers and road markings: the finishing work that makes a new road safe to use, by day and by night.
How a road is built
A flexible pavement is a stack of layers, each spreading the load of the traffic to the one below. Every layer is laid and compacted to the design thickness and levels before the next one goes down.
The surface traffic runs on: smooth, dense and sealed against water.
Bonds the surface to the base and spreads the load.
Crushed aggregate mixed with water and compacted: the main load-bearing layer.
Graded granular material that supports the base and drains water away.
The top of the embankment, compacted and tested for density.
Earth built up in compacted layers to the design level.
Quality
Road contracts in India are usually built to the Ministry of Road Transport and Highways (MoRTH) Specifications for Road and Bridge Works and the codes of the Indian Roads Congress (IRC). We build to the drawings and the specification in each contract.
Every material and every layer is tested against the specification before the next one goes down, and the records are kept for the client's engineer.
Questions
New roads, widening and strengthening of district, rural and urban roads, with the drains, culverts, road furniture and markings that go with them. We also build highways, bridges, and bituminous and concrete pavements.
To the drawings and the specification in each contract. For most road work in India this means the Ministry of Road Transport and Highways Specifications for Road and Bridge Works and the codes of the Indian Roads Congress.
Yes, where the contract needs it. Every work zone next to live traffic is signed, barricaded and managed by flag persons, and everyone on site works in full personal protective equipment.
