We should thank Tony Boyle for some clear thinking on this subject
Dr Tony Boyle warns about the meaning of the ‘pre-construction phase’ in the 2015 Construction (Design and Management) Regulations. Offering tips on how to avoid this pre-construction phase problem and reducing the extent to which you have to revise your CDM documentation.
The intention of CDM 2015 appears to have been to allocate responsibility for health and safety before construction work begins to principal designers, who would hand over this responsibility to principal contractors when construction work started. This is clear from regulations 11(1) and 13(1) which are reproduced below.
11.—(1) The principal designer must plan, manage and monitor the pre-construction phase and coordinate matters relating to health and safety during the pre-construction phase to ensure that, so far as is reasonably practicable, the project is carried out without risks to health or safety.
13.—(1) The principal contractor must plan, manage and monitor the construction phase and coordinate matters relating to health and safety during the construction phase to ensure that, so far as is reasonably practicable, construction work is carried out without risks to health or safety.
As you can see from these regulations, the duties are word-for-word identical and only the phases differ (pre-construction or construction). However, the definitions of pre-construction phase and construction phase are:
“pre-construction phase” means any period of time during which design or preparatory work is carried out for a project and may continue during the construction phase.
“construction phase” means the period of time beginning when construction work in a project starts and ending when construction work in that project is completed;
I’ve put ‘may continue during the construction phase’ in bold to emphasise the fact that this makes the definition meaningless. How can it be pre-construction if it is carried out during construction?
We are strongly advising our CDM clients not to use the term pre-construction phase at all but to use ‘design and preparatory work phase’ instead. This clearly indicates what the phase is about, and uses the CDM definition wording, but does not tie it to any particular phase of construction.
A practical problem also arises because instead of either the principal designer or the principal contractor being responsible for health and safety it is likely that, at least early in the construction phase, they will be sharing the responsibility. You will have to think through how this dual working can best be managed in your organisation.
