Who are designers? (1)
  • A ‘designer’ has a wide definition under CDM 2007
  • If you design or specify building work, then you are a designer with duties under CDM
  • Duties apply to all projects, including non-notifiable and domestic
  • It includes people who prepare
    • Drawings
    • Design details, analysis and calculations
    • Specification and Bills of Quantities
  • The design could be on paper, computer or verbal

Who are designers? (2)
  • Designers include
    • Civil and structural engineers
    • Building services engineers
    • Those specifying or purchasing materials
    • Temporary works designers
    • Interior fit out designers
    • Clients who specify
    • Design and construction contractors
    • Statutory bodies that require features that are not statutory requirements
  • Statutory requirements are exempted i.e. Building Regs requirements are not designs under CDM 2007

CDM 2007 Designers – Slide 3

Who are designers? - Overseas designers
  • Where the design work is undertaken by oversees designers, the designers duties under CDM 2007 falls on:
    • Person who commissions it if in GB or
    • The client for the work

CDM 2007 Designers – Slide 4

duties on designers 1
Duties on designers (1)
  • Designers have to:
    • Ensure clients are aware of their duties
    • Make sure they (the designer) are competent for the work they do
    • Co-ordinate their work with others as necessary to manage risk
    • Co-operate with CDM co-ordinator and others
    • Provide information for the health and safety file

CDM 2007 Designers – Slide 5

duties on designers 2
Duties on designers (2)
  • Designers have to avoid foreseeable risks SFAIRP by:
    • Eliminating hazards from the construction, cleaning, maintenance, and proposed use (workplace only) & demolition of a structure
    • Reduce risks from any remaining hazard
    • Give collective risk reduction measures priority over individual measures

CDM 2007 Designers – Slide 6

duties on designers 3
Duties on designers (3)

Designers must also:

  • Take account of the Workplace (Health, Safety & Welfare) Regulations 1992 when designing a workplace structure
  • Provide information with the design to assist clients, other designers, & contractors
  • In particular – inform others of significant or unusual/ “not obvious” residual risks

CDM 2007 Designers – Slide 7

duties on designers 4
Duties on designers (4)
  • Designers have to be given relevant information by the CDM co-ordinator
  • Risks which are not foreseeable do not need to be considered
  • CDM 2007 does not require “zero risk” designs
  • Amount of effort made to eliminate hazards should be proportionate to the risk

CDM 2007 Designers – Slide 8

hse s expectation of designers apply the eri c principles 1
HSE’s expectation of Designers - apply the ERI(C) principles (1)

Eliminate hazards

  • By experience
  • By red amber green lists (optional)
  • By challenging existing practice
  • By considering implications of their actions
  • By talking/listening to contractors
  • By complying with Workplace (Health, Safety and Welfare) Regulations 1992

Reduce remaining risks

  • Collective measures
  • Individual measures

HSE’s expectations of designers – apply the ERI(C) principles(2)

Inform others

  • Provide relevant information to project team: other designers, CDM co-ordinator, contractors
  • In particular: highlight significant, “not obvious” risks, & those that are difficult to manage

designers information
Designers - Information
  • Provide the right information to the right people at the right time
  • How to inform
    • Method of informing is optional
    • Notes on drawings
    • Written information with the design
    • Suggested sequence of construction (only if not obvious)
  • If in doubt – discuss it

CDM 2007 Designers – Slide 13

designers co operation
Designers – co-operation
  • A more managed approach will be necessary for larger projects:
    • integrated team involving designers, principal contractor and other relevant contractors
    • the appointment of a lead designer, where many designers are involved
    • agreeing a common approach to risk reduction during design
    • meetings of the design team (including the CDM co-ordinator) with contractors, and others
    • regular reviews of developing designs
    • encourage site visits, so designers can see how risks are managed on site and vice versa

CDM 2007 Designers – Slide 14

designers paperwork
Designers - Paperwork
  • Competent designers eliminate hazards and reduce risks – manage the risk, not paperwork.
  • Design risk assessments (DRAs) are seen by many as unhelpful and should be discouraged
    • Just say no to thoughtless DRA but yes to eliminating hazards
  • CDM 2007 does not require designers to produce copious amounts of paperwork detailing generic hazards and risks

CDM 2007 Designers – Slide 15

designers records
Designers - Records
  • Designers under CDM 2007 are not legally required to keep records of the design process
  • But
    • Brief records why key decisions were made will be helpful when designs are passed to another, to prevent decisions being reversed for the wrong reasons

CDM 2007 Designers – Slide 16

designers design review
Designers – design review
  • A process of design review will help to ensure buildability, usability, & maintainability
  • Designers should involve the contractor when reviewing buildability
  • Designers should involve the client (or building operators) when reviewing usability and maintainability
  • Involve the CDM co-ordinator if project is notifiable

CDM 2007 Designers – Slide 17

additional duties for notifiable projects
Additional duties for notifiable projects
  • Check that the client has appointed a CDM co-ordinator
  • Only ‘initial’ design work is permitted until a CDM co-ordinator has been appointed
  • Co-operate with the CDM co-ordinator, principal contractors and with other designers or contractors so all can confirm with their CDM duties
  • Provide relevant information for the health and safety file

CDM 2007 Designers – Slide 18

designers do not
Designers - “Do not……”
  • And never have been asked to control risk on site - they can only influence what is within their control
  • Take into account unforeseeable hazards and risks
  • Design for possible future uses of structures that cannot reasonably be anticipated from their design brief
  • Specify construction methods, except where the design requires a particular construction sequence
  • Exercise a health and safety management function over contractors or others
  • Have to consider trivial risks

CDM 2007 Designers – Slide 19

designers key messages
Designers – Key messages
  • If you design or specify building work, then you are a designer with new duties under CDM
  • Competent designers eliminate hazards and reduce risks – manage the risk, not the paperwork
  • Design for safety and health for those that build, use, maintain and demolish – it’s safer by design
  • Tell others about significant risks which remain – give the right information to the right people at the right time
