What is Constructability?

  • Constructability is a project management technique to review construction processes from start to finish during the pre-construction phase.
  • It is used to identify obstacles before a project is actually built to reduce or prevent errors, delays, and cost overruns.

Who can benefit from Constructability Reviews?

  • Builders
  • Architects
  • Structural Engineers
  • Developers
  • Home Owners

What will you receive with your Constructability Review?

  • Back-office consultations for our clients, working with you and your team to resolve issues.
  • The Constructability Review – a graphic PDF detailing issues, clashes, omissions and specifics needed prior to building.
  • The 3D structural model for clients and their customers, trades and vendors to access and study during construction.

What is the process in working with Constructability?

  • Provide us with construction documents in PDF form (architectural drawings, structural engineering drawings/specs., site plan, etc. — any applicable documents/drawings)
  • Provide us with engineered truss drawings, if any (floor and/or roof) and 3D DWG/DXG files obtained from truss vendor
  • Provide us with any topographic data available if a site model is desired (from surveyor or engineer)
  • We require a 50% deposit prior to starting your Constructability Review
  • A 3D model of the proposed structure is created from the provided architectural drawings to include structural elements (beams, headers, columns, etc.) and will work with truss vendor to incorporate floor/roof trusses into the 3D model.
  • The model contains scenes of the various stages of construction.
  • When site models are requested, we can generate a site model based on provided existing and proposed contours
  • As the model is being generated, we are reviewing the construction from the footings up to make sure all bearing walls have proper bearing, identifying clashes, errors and omissions.
  • We will generate a report detailing our findings/issues — this is the “Constructability Review”, which will then be shared with you.
  • We will work with your after the report has been generated to resolve issues and discuss conflicts.
  • We will then issue our final invoice for the balance of the contract price agreed upon.
  • 3D model and final Constructability Review report is released.

What is included in The Constructability Review?

  • The Constructability Review is provided in a graphic PDF format and identifies any issues, clashes or questions that need additional clarification found while compiling our model for review
  • Construction drawings are incorporated into the report with annotations, mark-ups and images relating to the issues taken directly from our 3D model generated while compiling our constructability review.
  • Common findings in a Constructability Review are:
    • Dimensional discrepancies between architectural drawings and engineered trusses (sheathing to sheathing vs. framing to framing dimensions)
    • Bearing walls, point load and continuous loads with no bearing below
    • HVAC issues such as floor truss duct chases not aligning, obstacles for supply and return ducts
    • Toilets and other plumbing drains directly above trusses or specified floor systems
    • Missing details for specific framing-related features
    • Roofing issues not observed in 2D become obvious in the 3D model

How much does a Constructability Review cost?

The average fee for a Constructability Review  is $0.50 – $1.50 per square foot.

Square Footage calculations take into account all under roof areas including covered decks/porches, finished and unfinished square footage, garages and any additional areas attached or detached that are to be included in the constructibility review.
