Welcome to Constructability 3D
“Constructability is a project management technique to review construction processes from start to finish during pre-construction phase. It is to identify obstacles before a project is actually built to reduce or prevent errors, delays, and cost overruns” – Wikipedia
More About Constructability Reviews
Constructability3D offers Constructability Reviews and Visualization Services for builders, architects, developers and homeowners.
It is common in the construction industry to have an architect or designer’s set of plans, a structural engineer’s drawings, and a truss manufacturer’s drawings- with no interaction or communication between them. It is often left up to the builder to determine constructability (“by others” or “verify with builder”).
We combine our many years of experience in the construction industry (custom home builder/designer for last thirty years) and 3D modeling to build detailed 3D structural models, BEFORE the project is built, identifying clashes and costly mistakes, as well as providing an impressive 3D model to be used as a guide and reference during construction.
Constructability Reviews include the creation of a detailed 3D structural model for the proposed structure, including specified structural members, floor and roof trusses (files provided by client or client’s vendor/engineer). Using the architect or designer’s floor plans, sections and elevations, we build the foundations, wall framing, floor and roof systems. When engineered trusses (floor and or roof) are utilized, these trusses are modeled and placed on the structure exactly as they would be in the field. More times than not, issues, some major, are detected once visualized in 3D vs. 2D study. Specified structural members (beams, headers, etc.) are modeled and placed into position for study. Stair framing is generated to ensure proper headroom, etc. Penetrations for toilets, etc. are generated to make sure there is no clash with floor structure below (common issue – toilet over a truss, for example). HVAC duct chase are evaluated for clashes. Site models may also be generated, when provided with site plans and topographic data, to study terrain, sub-foundations and site issues. A thorough report is generated, by an experienced builder, to note all findings in an effort to resolve issues prior to construction. We bring team members together in a cloud-based system to address issues and resolve them pre-construction. The stated goal for this “back-office” service is that we save more money from costly mistakes than our fee. We provide another “set of eyes” during pre-construction project management.
Visualization Services: Once the 3D structural model has been generated, clients often wish to complete the exterior finishes, site models, and interior finishes. Renderings, animations, virtual tours, VR are all available.
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.
