BIM - Building Information Modeling

M-SC--ABC-REV-8-19-05-Model-(1)-(2)B&W Mechanical Contractors has been producing 3D coordination drawings for more than a decade.  Prior to the implementation of the BIM process, we produced 3D drawings in areas that were particularly congested and needed a higher level of coordination.

B&W Mechanical Contractors has been utilizing the BIM process since 2007.  Since then, our project coordinators have completed more than 2.5 million sqft of BIM coordination drawings. We utilize AutoCad MEP 2010 and Navisworks. We have built an extensive library of not only the mechanical and plumbing pipe, valves, and fittings, but also HVAC and plumbing equipment and fixtures. This library enables us to produce the most accurate reflection of what is actually being installed in the field.

B&W Mechanical Contractors utilizes the BIM process during the preconstruction, construction, commissioning, and closeout phases of projects; project delivery method dependent.

Submittal Party

The Expedited MEP Submittal Review is an intensive, fast-paced, comprehensive, and coordinated review of product submittal data by all appropriate design and construction participants.

The goal of the “MEP Submittal Party” is to review, process, and approve all MEP equipment submittals over a 3 to 5 day time frame (project dependent) in order to allow each of the subcontractors to immediately proceed with equipment procurement and begin the work on the “contractors coordination drawings”. This concentrated approach should significantly reduce the time and effort normally required to process submittals. In addition, this dialogue between all interested parties provides for a better understanding of earlier project design decisions and allows for resolution of preliminary coordination issues. This review format provides direct feedback to the subcontractors and manufacturer representatives on contract document requirements, thus allowing submittals, in most instances, to be revised as necessary on the spot.

Each MEP subcontractor and their suppliers must prepare complete and fully coordinated equipment product data submittals for all system components prior to the start of the review meeting in accordance with the format detailed in the contract documents. This includes all subcontractor and manufacturer certification stamps.

All interested project participants: Owner; Architect; Engineer; General Contractor; HVAC, Plumbing, Electrical, Fire Protection, Security and Building Management and Control System Subcontractors; major equipment manufacturer representatives. Subcontractors and manufacturer representatives should be advised that this process may require substantial effort during the review sessions – this means that qualified personnel must be on hand and that immediate access to support resources in their home offices may be needed and should be made available.

All equipment submittals and product data, specification compliance reports, manufacturers certifications, etc., as described in the MEP and BMCS Specifications. Provide the number of complete copies as indicated. “Shop Drawings” (e.g. ductwork layouts, fire alarm wiring diagrams, etc…) are not expected to be ready until after the “Coordination Drawings” are complete and should be submitted through the normal process at a later date. If a subcontractor requires a review of any critical Shop Drawings, they can be submitted at the party if they are complete and coordinated with all trades.
Note: This process is effective only if the subcontractor produces quality submittals that are in accordance with the requirements of the Contract Documents. Submittals that in the opinion of the Owner/Consultant are poorly prepared and/or incomplete will not be reviewed and will require resubmittal through the normal process.

Approximately 4 to 6 weeks after notice to proceed is given by the General Contractor to all MEP Subcontractors (project dependent).

At a location as determined by the Owner and General Contractor. The meeting room or rooms should be large enough to have 3 ongoing discussion groups (e.g., HVAC, Electrical, and Building Controls simultaneously) with between 5 and 10 people per group. The room should be equipped with telephones, fax machines, and copiers for the exclusive use of all participants. At least 2 full sets of contract documents should be on hand. Past Submittal Parties have been held successfully at job site trailers, hotel conference rooms, and general contractor offices. The location must allow for the non-interrupted focus of all parties.

Construction Staging, Delivery and Management

When the project is ready, a list of equipment and the required submittal manufacturing and shipping time required will be accumulated from this equipment list and the scheduled items will be identified that need to be purchased early to ensure that delivery will be timely to minimize the cost of the construction. In a coordinated effort with the delivery scheduling, the construction staging plan will stage each area of the construction and equipment deliveries to maximize the efficiency on site and minimize stored material and clutter in what will become a very congested construction site. This coordination of deliveries and construction staging plans will then fold into a site management plan which would lay out site offices, site storage and the use of space on the site. This site management plan would be developed with each member of the construction team to provide the most efficient overall site management for the entire team.


made in the USAOne of the most important factors to control cost and quality in the mechanical contracting industry is to have state of the art prefabrication facilities, to employ highly trained workers to operate these facilities and to provide ongoing training to these workers. B & W Mechanical Contractors, Inc is at the forefront in these endeavors.

Prefabrication maximizes the strategy of removing labor from the field and implementing as much labor as possible in a controlled environment. The benefits include increased productivity, greater quality control, shorter on site durations saving time on the project schedule, and improved overall project safety. The bottom line means lower costs for the client. B & W Mechanical Contractors, Inc has been performing prefabrication services for over 20 years.

Our prefabrication services include:

  • Coil connections and assemblies
  • Pump assemblies
  • Welded joints and fittings
  • Plumbing assemblies
  • Fixture assemblies

The Quality Assurance Program, or applicable revisions thereto, necessitated by specific project requirements, shall be implemented at all levels.

Commissioning & Turnover

From the inception of a project B & W Mechanical is planning commissioning and closeout. When our project team holds its 2-3 day preplanning session, the job is pre-planned from the end to the beginning, rather than from the beginning to the end. This not only includes schedule, but also notices, as-builts, owner training, operation and maintenance manuals, and warranty.

During the project pre-planning session a commissioning checklist for this specific project is developed. It includes all equipment and systems testing required by the specifications as well as start up for each individual piece of equipment and all control points. Once commissioning begins, the checklist will be utilized and each system will be methodically checked out. A commissioning log and report will be maintained on the job site. It will include start-up reports from equipment manufacturers, pump alignment verification, and point by point controls listing and verification, and all service call information on any equipment which requires repair before final completion.
