FAQ’s

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.
  • A Virtual Tour (panoramic and virtual reality) allowing viewers to tour the proposed structure in detail on mobile devices and computers.
Our Goal is that you save more money utilizing our services than you spend on them!

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, virtual tour 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 .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.

Constructability3D and BIM, Explained…

BIM, an acronym for “Building Information Modeling”, is a process for interaction between all parties involved in the lifecycle of a building, from design, through construction and ultimately its end use.

  • 2D Drawings are used to convey the design intent for contractors and trades to construct the building.
  • 3D models are generated from the 2D documents to provide visualization of the building.
  • 4D involves an element of time (the construction schedule)
  • 5D involves an element of cost (the construction budget)
  • 6D involves the lifespan of the building and its components after completion, including warranty and maintenance requirements.

Constructability3D uses the client-provided 2D architectural and structural drawings, as well as site plan drawings to build detailed structural models for the project. When applicable, floor and or roof truss model files are obtained from the client’s vendor and imported into the model for study and visualization. A comprehensive Constructability Review is generated for each project, a graphic PDF report detailing issues discovered during the modeling process. Essentially, we build it BEFORE you do!

Constructability4D – Every 3D model is broken out into Scenes that build upon each phase of construction – a timeline of construction. From foundation,framing, floor systems and roof systems, each model ensures simple navigation between phases.

Constructability5D – 3D modeling geometry contains attributes of length, area and/or volume. These attributes are used in performance of quantity takeoffs and ultimately the construction budget. Our models are generated in such a way as to obtain takeoff data for many of the building’s components and this data may be provided to our clients as part of our services.

Constructability6D – We provide our models to our clients for their use throughout the building process and beyond. These models remain as a tool for study after the occupant has moved in and in-use.
