Construction (Design and Management) Regulations 2015: Guidance

The Construction (Design and Management) Regulations 2015 have now taken effect. These will affect people that work on site as well as procurement professionals within the construction industry.

The changes to the regulations aim to:

  • Improve health and safety in the construction industry, particularly on smaller construction sites.
  • Cut back on red tape to reduce the admin burden on SMEs and make bidding for work more accessible.

Key changes to the regulations include:

  • Replacement of the CDM Co-ordinator (CDM-C) role with a Principal Designer responsible for health and safety in the design team.
  • Before work starts on site, the client is required to appoint a Principal Designer and Principal Contractor – while ensuring that these are able to demonstrate that they can deliver the project in a way that ensures health and safety best practice.
  • Client duties have been extended to cover domestic projects. These duties are normally transferred to the Principal Contractor.
  • A construction phase plan will be required for all projects.
  • The client must notify the HSE of any projects that are expected to last more than 30 working days (with more than 20 persons on site).

These regulations may increase the burden on the buyer’s procurement teams. However, by adopting Safety Schemes in Procurement (SSIP), buyers will further decrease the amount of admin they are required to do. This is because suppliers with an SSIP member scheme will have already met the required health and safety criteria at stage one of the assessment process, meaning that they will have more time to focus on the project specific requirements.

As a part of the Constructionline supplier assessment process, we accept all SSIP member assessment schemes as proof of a supplier’s health and safety management competency. This also means that all Constructionline registered buyers adopt the principles of SSIP.
