Temporary Works Access Equipment – Construction [Case Study]

Development of construction industry temporary works access-stair tread system for ultra-fast onsite assembly.

Innovolo carried out a full ideation and specification development for a unique access-stair tread system used in temporary works, designed in accordance with the National Access and Scaffolding Confederation (NASC) Health and Safety Guidance note SG25:14 and BS 5395 Code of practice for the design of stairs for limited access.

26% of fatal injuries by workers were caused by a fall from height.

The Working at Height Regulations (WAHR) 2005 state that ladders should only be used for work at height if a risk assessment under Regulation 3 of The Management of Health and Safety at Work Regulations 1999 has demonstrated that the use of more suitable work equipment (e.g. a staircase) is not justified because of the low risk and short duration of use, or there are existing features on site which cannot be altered.
The Construction (Design and Management) Regulations (CDM) outlines that clients, CDM co-ordinators and designers should consider what form of access may be needed at the planning stage. This should include any emergency escape routes that have been identified by the risk assessment and preferred option for access/egress and the required number of access points.
On larger projects powered passenger/goods hoists may be a safer option if available. Where passenger hoists are used, an additional means of access will be required for emergency purposes (e.g. in the event of a fire or mechanical failure).
All equipment, including staircase components and ladders, must be inspected and maintained in compliance with the Provision and Use of Work Equipment 1998 (PUWER 1998) and all relevant British and European Standards.
On existing buildings it may be possible to use permanent staircases to gain access to the scaffold; however, for many applications the starting point for consideration by the client should be an access staircase that can be adapted to suit all scaffold types, followed by ladder access towers or bays.

    This was a groundbreaking new product development. I like how it conforms to all the safety standards.

    I wish I could see what the actual product design looked like. Kudos on the successful project!

    This was a good solution to a real problem. Good to see that the innovation reduced the number of accidents in construction sites.

    I wish you also covered the ROI gained on this project. I believe it was a big financial success though.

    Would love your thoughts, please comment.x
