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?
- Structural Engineers
- 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 – $1.00 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.
