Our approach to design

Technical review

GBE ensure that at the beginning of each new project a full technical review of each system is undertaken prior to the commencement of detailed coordination drawings. This protects both GBE and our clients from significant cost risk if engineering issues are not identified until late in the project life cycle.

In order to ensure these checks are robust and thorough we start our review by validating the building loads, primary plant/equipment loads against the relevant CIBSE and BSRIA guidelines as well as our experience of relevant past projects.

Dependent on our scope GBE may carry out thermal modelling and full validation of loads from first principles. Building and plant loads are confirmed and agreed with the design team.



GBE then commence the review and development of the detailed schematics.

We ensure that they are efficiently laid out whilst considering all aspects including: 

  • commission-ability
  • expansion
  • optimum circuitry and plant efficiencies
  • interaction of circuits and equipment

Optimum system parameters:

  • temperature selection,
  • LV distribution/capacity
  • discrimination report
  • infrastructure capacity and its parity with design loads
  • life-critical supply autonomy checks
  • confirmation of cables/pipe sizing etc. 



Once the schematics are finalized and plant selections have been made, GBE proceed with producing fully coordinated 3D models in line with the project prefabrication/modularization strategy.

This is using actual plant BIM models (where available), detailed supports/bracketry etc. to produce a fully coordinated 3D model.

Once this is finalized and agreed with the client and design team, detailed construction end sheet drawings are produced, as well as module and spool drawings for manufacture of pre-fab/modules.

Where required, GBE are also able to, alongside the architect, generate RCP fully compliant with fire alarm and sprinkler regulations.


GBE use the project information system and our internal RFI schedule to raise any queries as a result of the above checks. Detailed validation calculations, technical submittals and schedules are submitted for all proposed design validation/development and plant/ material selection to ensure collaborative working with the design team.
