Industrial piping and civil works

An industrial installation is not limited to its structure. It has networks, their supports, and the concrete works that carry them. We handle these packages together, on the same site.

It is first of all a question of dimensions. A foundation block receives holding down bolts positioned to the millimetre against a skid; a trench follows the real route of a network, not a schematic. When those packages sit with two different contractors, those dimensions get lost — and the rework costs more than the saving expected at tender.

Piping

• Industrial fluid networks — process water, compressed air, technical circuits
• Spool prefabrication in the workshop, erection on site
• Supports — cradles, clamps, brackets, support steelwork
• Headers and drains
• Maintenance — section replacement, support renewal

Associated civil works

• Foundation blocks and plinths — equipment bases, anchors
• Trenches and technical pits
• Industrial slabs and floor repairs
• Ground beams and pad foundations for steel frames
• Reinforced concrete works — directly linked to our rebar workshop

Our process

1. Site survey — actual route, tie-in points, space constraints
2. Isometrics — piping drawings and spool schedule
3. Workshop prefabrication — cutting, bevelling, welding of spools
4. Support fabrication — cradles, clamps, brackets, support steelwork
5. Civil works — blocks, trenches, plinths, holding down bolts set to template
6. Site erection — installation, connection, alignment
7. Testing and handover — tests appropriate to the network, as-built documentation

Thermal movement: the point that gets forgotten

A network that heats up expands. Over a long run that expansion is measured in centimetres. If it is restrained by supports that are too rigid, the load transfers into the flanges, the branches and the foundation blocks.

That is why support layout distinguishes anchor points, which lock, from guides and sliding supports, which let the pipe move. A support of the wrong type cracks a concrete block within a few cycles.
