Types of Scaffold That Require a Design
→ all shoring scaffolds (dead, raking, flying) | → cantilevered scaffold | → truss-out Scaffold |
→ facade retention | → access scaffold with more than the 2 working lifts Chang | → buttressed free-standing scaffold |
→ buttressed free-standing scaffold | → temporary roofs and temporary buildings | → support scaffold |
→ complex loading bays | → mobile and static towers | → free standing scaffold |
→ temporary ramps and elevated roadways | → staircases and fire escapes (unless covered by manufacturers instructions) | → spectator terraces and seating stands |
→ bridge scaffold | → towers requiring guys or ground anchors | → offshore scaffold |
→ pedestrian footbridges or walkways | → slung and suspended scaffold | → protection fans |
→ pavement gantries | → marine scaffold | → boiler scaffold |
→ power line crossings | → lifting gantries and towers | → steeple scaffold |
→ radial / splayed scaffold on contoured facades | → system scaffold outside manufacturers guidance | → sign board supports |
→ sealing end structures (such as temporary screens) | → temporary storage on site | → masts, lighting towers and transmission towers |
→ advertising hoardings/banners | → rubbish chute | → any scaffold structure not mentioned above that falls outside the ‘compliant scaffold’ criteria in TG20 or similar guidance from manufacturers of system scaffolds. |
Scaffold Contractor's duties
At the start of the planning process, the scaffold contractor should supply relevant information to ensure an accurate and proper design process is followed; This should include:
Scaffold Designer's duties
Prior to installation:
The scaffold designer must provide relevant information about the scaffold. This should include:
The scaffold designer must provide relevant information about the scaffold. This should include:
→ site location
→ period of time the scaffold is required to be in place intended use |
→ height and length and any critical dimensions which may affect the scaffold |
→ number of boarded lifts |
→maximum working loads to be imposed and maximum number of people using the scaffold at any one time |
→ type of access onto the scaffold eg staircase, ladder bay, external ladders |
→ whether there is a requirement for sheeting, netting or brick guards |
→ any specific requirements or provisions eg pedestrian walkway, restriction on tie locations, inclusion/provision for mechanical handling plant eg: hoist) |
→ nature of the ground conditions or supporting structure information on the structure/building the scaffold will be erected against together with any relevant dimensions and drawings. |
→ any restrictions that may affect the erection, alteration or dismantling process |
→ type of scaffold required (tube & fitting or system)
→ type of scaffold required (tube & fitting or system) |
→ maximum bay lengths |
→ maximum lift heights |
→ platform boarding arrangement and the number of boarded lifts that can be used at any one time |
→ safe working load / load class |
→ maximum leg loads |
→ maximum tie spacing both horizontal and vertical and tie duty |
→ details of additional elements such as beamed bridges, fans, loading bays etc, which may be a standard configuration (see note 1 ref TG20:13) or specifically designed |
→ nformation can be included in relevant drawings if appropriate |
→ any other information relevant to the design, installation or use of the scaffold |
→ reference number, date etc. to enable recording, referencing and checking |
Scaffolding collapse Avoid a disaster!
Prior to scaffold erection contract a scaffolding designer in order to get a drawing and calculations to avoid accidents as captured in the video:
Cutting corners may cost lives!
Working unsafe; Avoid a tragedy!
While erecting scaffolding follow: Health & Safety rules like SG4:15 or RAMS and Design Risk Assessment. Cutting corners may cost lives!
Scaffold gun review:
Probably one of the best scaffold guns so far!
