FAQ
Questions, answered.
Straight answers on scope, quoting and how we work under main contractors.
01Steel fixing only, or concrete as well?
Both. We deliver steel-fixing gangs, concrete packages, or combined RC packages depending on your scope.
02What do you need for a quote?
Issued drawings, bar schedules where available, programme dates, site location and whether you need labour-only or a fuller package.
03Can you work under a main contractor?
Yes. We typically operate as a specialist subcontractor with inducted crews and site-ready documentation.
04Residential and commercial work?
Yes — housing, commercial frames, industrial slabs and civil RC elements.
