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 user should supply relevant information to the scaffold contractor to ensure an accurate and proper design process is followed. Typically this information 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

 

Scaffold Designer’s duties

Prior to installation: 
The scaffold contractor or scaffold designer must provide relevant information about the scaffold. This should include:

→ 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

 

Scaffold collapse 

Avoid a disaster!
Prior to scaffold erection contract a scaffolding designer in order to get a drawing & calculations and 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!
