Quantity Surveying

From smaller first-time home building to complex commercial construction developments, there can be endless costs and risks to try and manage. As professional quantity surveyors, TWG Associates can ensure projects are delivered on time, within budget and to the required standards.

As independent experts, we can work with you from initial concept to completion, providing cost estimates and control, risk and contract management, and final accounts. Which gives you more structure, reduced risk, and ultimately better value for money.

When do you need a quantity surveyor?

Even small building projects can encounter issues and spiralling costs, including extensions and renovations. Involving a quantity surveyor from the outset will ensure more accurate and reliable estimates, procurement and schedules.

You can then choose to manage the project delivery yourself, or work with us throughout construction and completion.

It’s never too early to contact us about future building and development work. By being involved from the outset, we can ensure that you’re setting realistic budgets, based on surveys, planning drawings, Building Regulations and any specific requirements involved, along with identifying potential risks.

The bigger the project, and the more time it takes, the more chance there is of disruption, risk and increased costs. We can work with you throughout the construction process with the right level of involvement to ensure that alterations or unexpected problems are managed correctly.
