What we do

Structural bolting at height

Structural bolting at height requires accurate torque application to specified values using calibrated torque wrenches or tension-indicating washers. Our teams carry out both snug-tightening and full-tensioning of structural bolts in accordance with BS EN 1090 and the project’s structural specification, with torque values documented and verified by our supervisory staff at each connection.

Site welding

Site welding at height is carried out using MMA (stick) welding or wire-fed processes depending on the application and environmental conditions. Our welders hold the relevant coded welding qualifications for structural application and work within the project’s welding procedure specifications. All welds are visually inspected and, where required, non-destructive testing is carried out by our inspection team.

Stud welding

We carry out stud welding for shear connectors, stud anchors and fixing applications at height, where the connection is part of a composite beam or facade anchor system. Stud welding at height requires specialist equipment that we operate safely from ropes, with appropriate restraint and anti-drop measures in place throughout.

Quality assurance & documentation

All bolting and welding works are supported by documented quality records including torque logs, weld inspection records and NDT results where applicable. These are provided in a format suitable for inclusion in the project quality plan and as-built documentation, giving the structural engineer and principal contractor a complete and auditable record of connection works carried out at height.

Why Think Access

Bolting and welding at height requires the same standards of workmanship and quality control as ground-level connections. Think Access delivers that standard from ropes, with documentation to match.

F.A.Q’s

Yes. Our welders hold current coded welder certificates for structural application in accordance with BS EN ISO 9606-1. Certificates are available for inspection on request.

Yes. Our teams can carry out both operations in sequence, which simplifies programme management and reduces the number of access visits required.
