Testing and Investigation for UK Construction Projects
Construction projects depend on accurate information about the site, ground, and materials being used. From early investigation and planning to quality control during the build and post-build assessment, construction testing helps project teams confirm suitability, identify potential issues, and demonstrate that works meet necessary specifications.
At CTS, we regularly work with contractors, developers, engineers, consultants, and construction professionals across the project lifecycle. Whether you’re looking for a single construction test or a coordinated programme, our nationwide laboratory and field capability gives you access to practical technical support around your project requirements.
Supporting a Changing Construction Sector
Today’s construction and building works industry faces growing expectations around safety, sustainability, efficiency, and building performance. Alongside evolving regulations, project teams must also manage continued cost and resource pressures, workforce shortages, and the complexity of adopting new and advanced technologies.
With so many priorities now shaping project success, reliable site and materials data offers teams a stronger basis for planning, compliance, quality control, and risk management. Our experts support this with independent testing and investigation at every stage, helping clients stay informed, respond to changing requirements, and make confident decisions as work progresses.
Our Construction and Building Works Testing Services
We provide UKAS-accredited laboratory and on-site testing throughout all phases of construction and building works, supporting initial site investigation and earthworks, construction materials testing, quality control, and the assessment of completed and existing structures.
We can help with:
- New-build residential developments
- Commercial construction projects
- Extensions and alterations
- Refurbishment and change-of-use projects
- Brownfield regeneration
- Civil engineering and enabling works
- Existing building and installation inspections
Need reliable testing for your construction project? CTS provides the insight needed to support key project decisions so you can move forward with confidence.
Integrated Site and Laboratory Construction Testing
Construction testing typically combines measurements taken directly on site with detailed analysis under controlled laboratory conditions. We can manage both, helping clients build a more complete picture of material properties and site performance.
On-Site Construction Testing
Our nationwide field teams carry out sampling and in-situ testing to collect information directly from the materials and conditions encountered on site.
Construction Testing Laboratories
Our UKAS-accredited laboratories provide physical, mechanical, and chemical testing for applicable construction materials, producing independent and traceable results.
Mobile Laboratories
For projects requiring tests close to the works, we can mobilise site laboratories to enable responsive access to testing and analysis throughout construction.
Independent Testing for Better Construction Decisions
Trusted, impartial testing and investigation delivers the evidence that construction and building works teams need to understand site conditions, confirm material performance, assess existing structures, and respond to issues with greater certainty.
Reliable test data can support:
- Compliance with project and regulatory obligations
- Early identification of ground, material, and structural risks
- Quality control throughout construction phases
- More informed use of materials and project resources
- Reduced risk of defects, rework, and avoidable delays
- Contamination assessment and responsible material management
- Refurbishment, repair, and change-of-use decisions
- Detailed assessment of existing buildings and structures
Quality, Compliance, and Accreditations
Our strength in construction and building works is backed by industry-recognised accreditations, reflecting our dedication to maintaining the highest standards across our laboratories, technical services, and site operations. We hold UKAS accreditation ISO/IEC 17025 for applicable laboratory testing activities, in addition to further industry accreditations.

Frequently Asked Questions
What is construction materials and testing?
Construction materials and testing (CMT) covers the examination of materials used to build structures and associated works, including soil, aggregates, concrete, earthworks materials, and asphalt. Testing establishes properties such as strength, composition, density, moisture, and classification to determine whether materials are suitable for their intended use and meet project specifications.
Who does soil testing for construction?
Soil testing for construction is typically carried out by specialist site investigation providers and construction testing laboratories, like CTS. Testing may take place directly on site or on soil samples taken to a specialist laboratory, depending on the properties and information that need to be established. We can deliver both on-site and laboratory soil testing for clients across the UK.
What is a construction test?
A construction test examines a material, site condition, or completed element to establish specific properties or check it against a project requirement. This can range from testing soil strength or concrete quality to determining aggregate properties or inspecting an existing building.
What construction materials can CTS test?
CTS tests a wide range of materials used in construction, including soils, earthworks materials, stabilised soils, concrete, aggregates, asphalt and other bituminous materials, and contaminated materials. Testing can take place on site, within our laboratories, or through a combination of both.
Why is soil testing needed before construction?
Soil testing offers important insight into the type, condition, strength, and other properties of the ground beneath a proposed construction project. These results give engineers and designers factual data they can use when considering foundations, earthworks, ground improvement, and other elements affected by site conditions.
What's the difference between on-site and laboratory construction testing?
On-site testing examines materials or conditions directly where construction is taking place, while laboratory testing analyses samples under controlled conditions. Many projects use both approaches, giving teams immediate data from site, alongside more detailed material analysis from a construction testing laboratory.
When is a site investigation required for construction?
Site investigations are generally carried out to determine how ground, groundwater, contamination, foundations, drainage, or other conditions could affect proposed works. The scope depends on the site, development, existing information, and decisions the investigation must support.
Can CTS support refurbishment and existing building projects?
Yes. At CTS, we provide building and structural investigation services for existing properties, including buildings being refurbished, altered, or considered for a change of use. Investigations can establish construction details, material properties, foundation information, and structural condition to produce factual evidence for engineers, surveyors, and project teams.
