RCC road construction cost for a factory or plant depends on the heaviest vehicle using the road, slab thickness and concrete grade, sub-grade and base work, joints and dowels, drainage and crossings, and whether the work is inside a running plant. Cheaper quotes usually cut base work, joints or drainage. Compare what is included, then get an exact quote after a site visit.
1. The heaviest vehicle
A road for cars, a road for forklifts and a road for loaded trailers and tankers need different slab thickness and base. Design for the heaviest vehicle that will regularly use it, not the average.
2. Slab thickness and concrete grade
Thickness and grade are the most visible cost items. They should come from the traffic loads, not from a standard rate.
3. Sub-grade and base layers
Weak soil needs more excavation, better filling and proper compaction. This is the part most often cut to make a quote look cheap, and the part that decides whether the road lasts.
4. Joints, dowels and sealing
Joint spacing, dowel bars and sealant add cost but control cracking. A quote without them is not comparing like with like.
5. Drainage and crossings
Side drains, culverts and sleeves for future pipes and cables are often left out of road quotes, then added later at a higher cost.
6. Working inside a running plant
Phasing around traffic, permits and night work can affect the schedule and cost. A new plot is simpler.
How to compare two road quotes
- Check slab thickness, concrete grade and reinforcement or dowels
- Ask what sub-grade and base work is included
- Check joint spacing and sealing
- Ask whether drains, culverts and crossings are included
- Ask how progress will be measured and reported
