Editorial update on 18 September 2026
Separate steelwork from groundworks
Request design, survey, excavation, foundations, supports, structure, treads, landings, guarding and handrails. Identify façade work and waterproofing. Do not present structural design as necessary only for escape stairs.
Include logistics and checks
Price transport, lifting, site protection, possible removal, fitting, repairs, waste and agreed checks. Assign escape-route validation and commissioning to suit the project. Establish access during work and handover documents.
Compare the same complete project
Request taxes, exclusions, payment stages and actual schedule. No fixed supplement per metre of height or level is established. Deduct funding only after confirmation. Alternatives must retain the defined function and safety requirements.

Frequently asked questions
Does grating prevent ice?
No. Plan suitable surface, drainage and winter maintenance.
Can a light stair avoid foundations?
Stability and supports need design; apparent low weight is insufficient.
