Introduction
Site investigation in relation to failing rock faces, soil slopes and retaining walls will often involve a degree of difficult access. Surfaces are commonly obstructed by facings or vegetation and there may be the need for intrusive testing.
Effective site investigation is a vital prerequisite to finding cost effective solutions to stability problems and significant savings can be made by clients who commission an SI to establish the likely mechanism of instability.
CAN's Capabilities
Access for tactile inspections is achieved by means of powered or rope access, whilst vegetation clearance is carried out using CAN's own NPTC qualified arborists.
Where ground investigation is required relating to steep or inaccessible slopes, CAN works with reputable ground investigation contractors to offer a range of intrusive drilling, testing and monitoring systems. These systems include probe drilling, window sampling and installation of piezometers and inclinometers with remote monitoring facilities.
Inspection reports are supported by photo-montages, stereonets and the results of stability analysis. As an experienced Design and Build contractor, CAN offers realistic budget costings for alternative conceptual designs - a real advantage to clients who are seeking budgetary approval for remedial works and require a high degree of cost certainty.
