3. Current process in scaffolding companies
Current working method up to the order
Requests
• Lots of requests for quotation
Type of
scaffold
• Simple or complex scaffold?
scaffold
Simple
scaffold
• Needs fast and precise bill of material and prices
• Nice presentation is an extra sales argument
Reality
• Often no drawing, no calculation checks
• Price based on rough estimations and experience

4. Current process in scaffolding companies
Current working method for complex scaffolds … up to the
order
Complex
scaffold
• In general … More details are needed
• Drawings, survey on site, basic / advanced checks
Drawing
• Drawings, cuts, views …
• Currently often in 2D
Checks
• Currently based on manufacturers tables
• Currently simple 2D checks on some critical points
Quantities
• Choice of scaffold elements (tubes, couplers …)
• Price based on estimation of quantities

• 2nd order is the preferred way of
analysis
• Equilibrium of the displaced system
is taken into account directly
Focus on safety
Increase safety in scaffolding – calculation rules
is taken into account directly
