Testing and analysis

Testing and analysis

In addition to our ground engineering capabilities, we are established providers of specialist technical services to the construction industry.

We offer a competitive service in the areas of:

Pile testing

We provide a range of pile testing and analytical techniques to the construction industry, backed by thirty years of experience and a proven track record. Our comprehensive, UKAS accredited, pile testing services include:

Dynamic pile testing
Cross hole sonic logging pile integrity testing
Transient dynamic response pile integrity testing

We also offer the following services:

  • Case pile wave analysis program (CAPWAP)
  • Sonic pulse echo pile integrity testing
  • The facility for undertaking GRLWEAP driveability desk studies

Using the latest test equipment, dynamic test data can be instantly transmitted back to the office from anywhere in the world and analysed using CAPWAP. This facility enables real-time analysis of the pile test data.

Environmental monitoring

We offer a full range of environmental monitoring services with flexible response times to suit your requirements. They include:

  • Contaminated land
  • Soil sampling and analysis
  • Water sampling and analysis
  • Legionella testing
  • Air quality monitoring
  • Gas monitoring

Diagnostic testing

We undertake structural, diagnostic and geotechnical monitoring on buildings, bridges, car parks and industrial premises. We undertake surveys of structures to assess the nature and extent of any defects, their probable cause and to allow development of repair strategies.

We offer expert advice with necessary site investigation, even in difficult locations such as cliff faces, for bore holes, trial pitting, embankment slips, geotechnical diagnosis and failure diagnosis. We also have in-house expertise in soils, rocks and man-made materials.

We specialise in diagnosing the condition of materials in all types of structures including reinforced concrete, post-tensioned and pre-stressed concrete, steel and iron, timber and all associated materials used in such constructions. We have tested bridges ranging from M25 viaducts to post-tensioned bridges at New Street Station, Birmingham, from wrought iron railway bridges to steel jetty structures and from timber based environmental towers through to safety glass in high-rise buildings.

We have in-house expertise on plastics, paints, coatings, cementitious and bituminous materials, epoxies, polyesters and other resins, radionuclides and toxicity of materials.

We have worked with a wide variety of customers including:

  • Governments
  • Local authorities
  • Utility companies
  • Consulting engineers
  • Contractors
  • Processing and manufacturing industries
  • Property developers
  • Independents

Structural monitoring

We offer a full structural monitoring service covering a wide range of structures including modern and historic buildings, monuments, bridges, tunnels, jetties, dams, pavements, pipelines, railways, industrial utility plants, earthworks and embankments.

We use state-of-the-art technology including:

  • Ground penetrating radar
  • Remote crack monitoring, tiltmeters and inclinometers
  • Strain gauging including residual stress measurement in post-tensioned structures
  • Ground remediation evaluation and assessment
  • Ultrasonics
  • Magnetostrictive surveys
  • Radiography and tomography
  • Acoustic and frequency monitoring
  • Seismic monitoring
  • Piezometers
  • Thermography
  • Photo-elastic analysis
  • Topographic surveys with real-time triggered alarm systems

We can produce bespoke solutions to complex challenges to solve one-off problems for you. If you would like further assistance or advice with your project please contact Fred Fountain on +(0)7896 159810.

Noise and vibration monitoring

Our comprehensive range of noise and vibration monitoring capabilities includes prediction, measurement and the control of both environmental and personal exposures to noise and vibration.

Our services include:

  • Short and long-term equipment hire
  • Attended or remote monitoring surveys
  • UKAS accredited sound insulation testing analysis of results and presentation of findings in detailed reports
  • Monitoring systems

Whilst targeted predominantly at the construction sector, these services are available for all industries or circumstances where noise and vibration are of concern.

Noise and vibration prediction

The noise predictions we provide for construction sites are undertaken using the methodology described in BS 5228 Part 1 and are processed using the latest version of CadnaA bespoke noise modelling software. Plant specific noise levels, obtained by measurement, are used whenever possible together with noise levels from the BS 5228 database where actual measurements are not available.

Vibration predictions, if required, are based on previous data obtained by measurement of similar operations in typical ground conditions.

Sound insulation testing

We are UKAS accredited for sound insulation testing for residential and commercial buildings. Testing is carried out in accordance with the Building Regulations Schedule E. We also offer an acoustic design and testing service for UK schools in accordance with Building Bulletin 93 through our partnership with Parsons Brinkerhoff.
