CMU COORDINATION DRAWINGS
MB BIM works with the general contractor, CMU contractor, and other trade contractors that require openings or grouted cells in the CMU to create drawings that locate these items. These drawings, including design questions, can be submitted and approved by the structural engineer and architect prior to installation in the field. When used alongside the MEFP Coordination process, we can ensure that these are reflected in the trade contractor install drawings.
This service includes:
-
Set-up model used to produce drawings
-
Link-in and correctly locate models or files provided by trade subcontractors to show on the drawings
-
Review architectural drawings for openings and details related to CMU
-
Review structural drawings for grouted cell and opening requirements.
-
Coordinate with GC and MEFP Trades to resolve conflicts or structural issues prior to installation
-
Coordinate with GC and CMU contractor to provide useful and constructible drawings.
-
Assist the client in producing RFI's
*Note that in order to get the most out of this service, it needs to be done in addition to the MEFP Coordination Lead Scope. Otherwise the information is only as good as the files provided to MB BIM by the trade subcontractors.
The advantages of this service include:
-
Coordinating all openings and grouted cells, prior to installation, increases field productivity because the location and coordination with other trades has already been established in the drawings at the time of installation. Delays in the field due to RFI's or questions to the design team and owner are significantly reduced.
Additional advantages of this service include:
-
Having a coordinated drawing where the location of openings and reinforcing is shown reduces rework in the field. Often times, the CMU installer does not know where the CMU jambs are for openings at the top of the wall when installing the rebar and grouted cells for the first course. Having these drawings as the installation starts, allows the CMU contractor to install correctly from the start. Rework in the field due to RFI's and questions to the design team and owner is significantly reduced because they were already answered during the coordination / submittal process.
-
Through the coordination and modeling process, more options can be evaluated resulting in a better product. The coordinated drawings are reviewed and approved by the design team and owner, confirming that the design intent is met. Finally, the drawings can be used to QA/QC the installed product.
