PI-8
Develop detailed install sequence
  • Develop detailed install sequence with sub and component manufacturer input to minimize inefficiency and overwork (refer to next section for guideline help).
  • Developing Project Specific Sequences.
 
  • Plug in component manufacturer install activities in place of conventional build tasks.
  • May change multiple tasks or phasing.
  • The key trades involved are the component manufacturer, framing/drywall, and MEP.
  • These trades will all want to go first, but the GC needs to coordinate and develop a project specific sequencing schedule with all parties involved prior to construction, to determine the sequence so minimize the effects of the burdens (many of which would be present even without modular components).
  • The sequence may be on a room by room basis or area by area.
  • Analyze critical path.
  • GC with sub and component manufacturer input develop detailed install sequence to minimize inefficiency and overwork.
  • Many contractors utilize a session similar to a large "MAP" day exercise with just the install team, framer, MEPs.

  • Sequence manufacturer component install, topping out framing, and OH MEP in sequence that best fits specific project details and subs.
  • Similar to sequencing priority walls or OH MEP.

  • Identify and review list of variables and constraints and evaluate how each one will impact each task and each other.
  • Choose the sequence that maximizes efficiency and minimizes impacts or burdens from other tasks and project specific constraints.
  • Coordinate (example: pull plan) with subs to determine the best work flow and sequence in each room, work area, and scope.
  • Allow any trades to coordinate and time each task not on critical path that best suits a smoother work flow for most.
  • General sequences for new construction allow for framing, OH MEP, and modular install to all start and run concurrent.
  • Fur downs can possibly be installed before modular units or the walls could be topped out after modular units just as MEP could layout ahead of framing or vice versa.
  • Vertical construction has the added challenge of major OH MEP runs able to start before framing while waiting on dry-in and roof to demo.
  • Tremble can be used to start top out framing ahead of MEP if desired by sub coordination.
  • Modular units install after roof demos. Amount of OH MEP and/or furdowns installed prior depends on dry-in time and sub coordination.
  • Consider identifying a leave out bay or 2 for rigging and setting equipment.
  • Access paths for modular units to be left clear until pods are all in (horizontal space and vertical).
