Detailed Design

Detailed design output builds upon the work carried out during the Schematic Design phase and crystallizes it into a design definition that can be built. Some of the outputs that need to be created during this Detailed Design phase are:

  • Final engineering calculations
  • Equipment lists
  • Equipment specifications
  • 2D plans
  • 3D models as required for clarification
  • Tender packages
  • Code compliance statements
  • Commissionability study
  • Building of LEED points
  • Permit drawings signed & sealed
  • Construction drawings

M&E engineers now make their final calculations for all of the system elements. This results in confirmed equipment schedules and specifications which include manufacturer names and even model numbers for some of the key equipment. Reticulation specifications are more generic in nature to allow increased flexibility during the tendering process.

Spatial designers and modelers now go to work on the final design plans for the building. Once again choices are made as to which technology to employ during this final integration and coordination phase. It is quite common to use 3D models to deal with difficult aspects of the building. For example, where space is at a premium or there are a significant number of services sharing the same riser or plant room entry/exit. Great care is taken to ensure that all plant, equipment, cabling, pipes and duct reticulation are integrated in such a way that they can easily be installed following a simple sequential procedure, and that they do not interfere with each other, that there is adequate ventilation, minimal noise, risers line up, cast in holes are in the right place, and incoming utilities are correctly terminated etc.
