Welcome, this month we are discussing the use of Construction Design Management Coordinators (CDMC). Simple Safety Advice offer this service to all clients, yet many people are still unsure of the role and when they legally need to ensure that a CDMC is involved in a project. If you are unsure then please get in touch.
What is a CDMC?
CDM co-ordinators (CDMCs) appointed by the project client are required to undertake the following actions:
• Advice and assistance – give advice and assistance to the client on what he needs to do to comply with CDM 2007 regulations
• Co-ordination and co-operation – ensure that arrangements are in place for co-ordination and co-operation during the planning and preparation phase;
• Pre construction information – identify and collect the pre construction information;
• Designer compliance – take steps to ensure that designers comply with their CDM duties
Which projects require appointment of a CDMC?
The client must appoint a CDMC on notifiable projects. These are projects likely to involve more than 30 days or 500 man days of construction work.
When should the CDMC be appointed?
The client must appoint a CDMC as early as possible and no later than after initial design work is completed.
‘Initial design work’ includes feasibility studies and any work necessary to identify the client requirements or possible constraints on the development.
Who needs to be informed of the appointment?
The CDMC must give notice to the Health and Safety Executive (HSE) as soon as is practicable after appointment.
Example of what happens if a CDM coordinator is not appointed
Three companies appeared at a Crown Court after a worker was trapped under a prefabricated wall and sustained serious injuries. Due to the design of the building the sub-contractors designed to erect a 10.4 metre long, 2.8 metre high wall flat on the floor and then manually lift the 1136kg wall into place. They raised the wall to waist height and were changing their grip when they decided it was too heavy and aborted the lift. One man’s legs got caught and became trapped under the wall, sustaining serious injuries and resulting in him needing wheelchair for a year. HE returned to work after 15 months but is still only able to perform light duties. The HSE specialist inspector for occupational health said “This case illustrates the importance of identifying hazards at the planning stage. This is the key aim of the Construction (Design and Management) Regulations 2007. If a proper risk assessment had been carried out, those involved would have realised that manual handling of the wall would have created a real and obvious risk to those present. As a result of this failure, someone sustained serious injuries that will affect him for the rest of his life, but which could so easily have been avoided. Corresponding fines and costs reached over £37,000.
Key elements to good CDMC involvement:
• Get your CDMC involved early to liaise with engineering contractors and design teams so that risks to the design outcomes can be identified quickly
• Ensure the Principal Contractor allows sufficient time for risk management to be identified before any work actually begins on site
• Ensure that all decision making parties are involved throughout the project to ensure that health and safety risks are managed appropriately
