Non-intrusive surveys are delivered using desktop study of construction and repair records and drawings to identify known asbestos containing materials (ACMs) contained within the structure prior to attending site to verify and further the desktop findings. Intrusive works include coring of bridge decks to access waterproofing materials, trial pits to access drainage behind bridge abutments / revetments, confined access surveys of viaduct sections, pumping stations etc. and high level surveys of bridges to inspect bearing shelves, sacrificial shuttering etc.

Our Highways Surveyors are supported by specialist trained Civils Operatives who assist in traffic management and opening up so that areas can be accessed for inspection sampling. All intrusive work is reinstated to a highways compatible standard including waterproofing and motorway running lane surfacing. 

We also provide several services to complement our surveying activities including coring of bridge decks to access waterproofing materials, trial pits to access drainage behind bridge abutments / revetments, confined access surveys of viaduct sections, pumping stations, and high level surveys of bridges to inspect bearing shelves, sacrificial shuttering etc. Through this approach we are able to deliver multiple solutions for our clients in an effective, safe and cost effective manner.
