Getting a price

What a pipework contractor needs to price a job

Published 21 September 2026 · 4 minute read

The short answer

Four things: the scope, in a sentence or a drawing; the site and when access opens; the programme you are working to; and anything already fabricated or on order. With those a pipework contractor can price the fabrication and the installation properly and tell you whether the programme holds.

Process pipework runs on the Discovery Park biomass plant

The scope

A sentence is enough to start: replace the clarifier pump pipework, run the fire mains on a new build, refit the process lines on a live plant. A drawing is better. What the price depends on is the line list, the sizes, the materials and how much of it can be fabricated before anyone is on site.

The site

Where it is, whether it is running, and when access opens. A line on a live steelworks is planned differently from the same line on open ground before the other trades arrive. Both are normal for KBVI; the price and the sequence change.

The programme

The dates that will not move. On a new build power station the fire mains go in first and everything waits on them. On an outage the window is fixed and the prefabrication has to be finished before it opens. Knowing the programme tells the contractor what to make in advance and how many people to bring.

What is already fabricated or on order

Spools already made, valves already bought, a previous contractor's work part done. None of it is a problem; all of it changes the price. Say so up front and the quote reflects what is actually left to do.

At KBVI the reply comes from the people who price the job and stand on the site. Email office@kbvipipework.co.uk or call the Scunthorpe office on 01724 622120.

Do you need full drawings to quote?

No. A sentence of scope and the site are enough to start a conversation. Drawings and a line list make the price firmer.

Do you price fabrication and installation separately?

They can be priced separately when a client wants only one, but most jobs are both, done by the same crew.

One email and the pipework starts moving. Your job gets priced by the crew that welds it and stands on the site from first spool to final test.
