What we do: cost management, delivery and final accounts
Three core services, delivered by the two people who founded the practice. Quantity surveying covers the money from feasibility to final account; project management covers the programme and the team; account reconciliation closes the job out cleanly. We also provide cost planning and estimating, contract administration, employer’s agent duties and JCT contract advice.

How we work, and why cost and programme belong together
WORK
We treat the client's money as if it were our own, and the programme as if we were the ones on site.
Trigon was founded by two quantity surveyors who have worked for national housebuilders, main contractors and bespoke developers. We run cost and delivery together, so the budget and the programme are managed by the same people, with one view of the risk.

Areas we cover: Newbury, Reading, Basingstoke, Oxford, Winchester and beyond
The practice is based in Newbury, which puts most of our work within an hour’s drive. We survey and manage projects across Berkshire and north Hampshire, in Reading, Basingstoke, Bracknell, Andover and Winchester, north into Oxfordshire around Oxford and Bicester, west into Wiltshire around Swindon and Salisbury, and east into Surrey around Guildford. Being local matters on a live site: valuations, variations and problems get dealt with in person rather than over email. Estimating and bills of quantities are drawn from drawings, so that work is taken on anywhere in the UK. See the areas we serve.

Frequently asked questions
What does a quantity surveyor do?
A quantity surveyor manages the money on a construction project. That means appraising viability before you commit, measuring the works and preparing a cost plan, drafting tender documents and comparing returns, valuing work as it is built, pricing variations, and agreeing the final account at the end.
When should I appoint a quantity surveyor?
As early as possible, ideally at feasibility. Benchmarking an early viability and testing the scheme against real rates is where the biggest savings are made, because the design can still change cheaply. Appointing after tender still helps, but the budget is largely fixed by then.
How does a quantity surveyor save money on a project?
By measuring properly rather than relying on rates of thumb, by value engineering the design before it is priced, by testing tenders against each other on a like-for-like basis, and by pricing every variation before it is built rather than months afterwards.
What size projects do you work on?
Typically schemes between £300,000 and £10 million in construction value, from individual private houses to residential developments of several hundred plots, along with sports, leisure, education and commercial work.
Do you work outside Berkshire and Hampshire?
Quantity surveying and project management are delivered across Berkshire, Hampshire, Oxfordshire, Wiltshire and Surrey, because those roles need regular site attendance. Estimating and bills of quantities are produced from drawings, so we take that work on anywhere in the UK.
Can you act as contract administrator or employer’s agent?
Yes. We regularly act as contract administrator, issuing instructions and certificates and running the contract on the client’s behalf. We also take on employer’s agent duties on design and build schemes where the appointment suits the project.
Which building contracts do you work with?
We work across the JCT suite, including Standard Building Contract, Intermediate, Minor Works and Design and Build, as well as bespoke developer agreements and subcontract forms. We will advise on which form suits the procurement route before you commit.
What is the difference between a quantity surveyor and a project manager?
The quantity surveyor looks after cost: budgets, tenders, valuations, variations and the final account. The project manager looks after delivery: appointing the team, setting and holding the programme, running meetings and reporting on progress and risk. On many projects the two roles are split between firms. At Trigon the same people can carry both, so the budget and the programme are managed with one view of the risk.
