Industrial units
built to work.
Factory sheds, godowns and warehousing, where the floor takes more punishment than the roof and the building has to suit the machinery going into it.
01 — Scope
What the work covers
Site preparation
Levelling, compaction and drainage settled before anything is cast, because a floor is only ever as good as what sits under it.
Foundations & structure
Footings and columns sized for the span, the crane loads and the roof system the intended use requires.
Clear-span roofing
Steel structure and sheeting with the eaves height and column grid the operation needs — not the cheapest grid that stands up.
Industrial flooring
Hardstanding with the thickness, reinforcement and finish suited to the loads and traffic, and joints placed where they will not fail.
Services & utilities
Power distribution, compressed air routes, water supply, and the effluent or drainage a working floor produces.
Yard & access
Approach roads, turning circles and loading areas sized for the vehicles that will really use them.
02 — On site
What decides the outcome
The floor is the building
More industrial disputes come from a failing slab than from anything above it. Sub-base, thickness, joints and curing decide whether it lasts.
Column grid follows the machinery
A grid chosen purely for structural economy can make a plant layout impossible. Those two decisions belong together, early.
Drainage before concrete
Levels and falls are close to impossible to correct once the slab is down, and standing water shortens the life of everything standing on it.
03 — Standards
Materials and workmanship
Sub-base decides whether the floor survives
Compaction tested in layers to the specified density before anything is cast. A slab is only as good as what sits under it, and a soft spot found after the pour cannot be fixed from above.
Slab thickness, reinforcement and joints to the real loading
Designed for the actual wheel loads, rack leg loads and point loads the operation will impose, not a nominal figure. Joint layout and load transfer matter as much as thickness - most industrial floor complaints are joint failures, not slab failures.
Floor flatness the handling equipment can live with
Narrow-aisle handling equipment and high racking need a tighter flatness than general storage. This is specified before the pour, because grinding a floor flat afterwards is slow, dusty and only partly effective.
Steel structure, span and corrosion protection
Sections and connections to the design spans and crane loading, with surface preparation and coating suited to what the building will hold. Coating over poorly prepared steel fails early regardless of the specification.
Roofing, drainage and the water that has to go somewhere
Sheeting, insulation where required, and gutters and downpipes sized for the roof area and local rainfall intensity. Undersized rainwater goods are a common shortcut and show up in the first heavy monsoon.
04 — The choice
Pre-engineered steel or RCC.
The structural choice for a shed or godown. It follows from span, loading, fire requirements and programme - not from which is cheaper per square foot.
| Aspect | Pre-engineered steel | RCC |
|---|---|---|
| Clear span | Long spans are its whole point; a column-free floor is straightforward | Practical at modest spans; long spans get expensive quickly |
| Speed on site | Fabrication happens off site while foundations are cast, so erection is fast | Sequential and curing-bound, so slower by nature |
| Heavy mezzanines and point loads | Possible, but needs designing in from the start | Takes them comfortably |
| Fire rating | Steel needs protection where the occupancy demands a rating | Inherently better, which can decide it outright |
| Future extension | Bays can be added along the length if the design allowed for it | Harder and more disruptive once cast |
| Maintenance | Coating and corrosion protection over the building's life | Little, beyond the roof and the joints |
05 — Sequence
How an industrial job runs.
No week counts here on purpose — on a site the duration is set by size, ground conditions and approvals. What each stage names instead is what governs its length.
Layout, loading and structure decision
Governed by the machinery and racking plan, not by the plot. Column grid, eaves height and floor loading all follow from what will stand on and move across the floor, and deciding them from a round number is what produces a building that cannot use its own volume.
Site preparation and foundations
Set by the ground. Levelling, compaction tested in layers, and drainage settled before anything is cast - a soft spot found after the pour cannot be corrected from above.
Structure and roofing
Paced by fabrication and delivery for steel, or by the casting and curing cycle for RCC. Rainwater goods sized for the roof area and local rainfall belong in this stage, not as an afterthought.
Flooring, services and yard
Driven by the floor specification, which is the part most likely to generate a complaint later. Joint layout, thickness and curing decide whether the slab lasts, and the yard is sized around the largest vehicle that will regularly use it.
06 — Handover
What you should hold at handover.
- Compaction and concrete test results for the slab, which is the element most disputes come from.
- The structural design and as-built drawings, so a later extension is a calculation rather than a survey.
- Services routed and tested to the points the process actually needs.
- A snag list closed against your checklist, with the site records handed over.
07 — Questions
Common questions.
What is a clear span and why does it matter?
An uninterrupted distance between supports, with no columns in between. It matters because internal columns dictate rack layout, aisle widths and vehicle movement - a grid that saves steel can cost far more in lost usable area over the building's life.
How thick should an industrial floor be?
It is a design outcome, not a standard number. It follows from the sub-grade, the wheel and point loads, the racking configuration and the joint layout. Anyone quoting a thickness before asking what will stand on it is guessing.
What eaves height should a warehouse have?
Set by the racking height plus clearance for the handling equipment, sprinkler provision and the lighting. Deciding it from the racking plan rather than from a round number is what avoids a building that cannot use its own volume.
Is a steel structure or an RCC structure better for a shed?
Steel is usually faster and gives longer clear spans; RCC can suit heavy mezzanines, particular fire requirements or where spans are modest. The right answer follows from span, loading, the required fire rating and the programme.
What services does a working floor need provided for?
Power distribution at the capacity the machinery needs, compressed air routes where used, water supply, and drainage or effluent handling for what the process actually produces. Routes are best fixed before the slab, not chased into it.
What should the yard be designed around?
The largest vehicle that will regularly use it. Turning circles, approach gradients, dock heights and hardstanding thickness all follow from that, and a yard that a trailer cannot turn in constrains the building permanently.
