The Cadence Apartments at Union Station presented many unique challenges and opportunities. From the beginning, the project design was delivered primarily in a 2D format. Only the structural information was given to (SIG) in a 3D format that was of use. (SIG) modeled the architectural information from the construction documents as well as all of the MEP. Fire protection was modeled through Design/Build which provided its own unique challenges throughout coordination. (SIG) also provided the coordination of all the self-performed concrete work. Sleeve coordination and penetrations were issued on documents used by the field team to ensure quality and clarity of installation. Additional coordination of all the post tensioned concrete decks with sleeves and penetrations provided critical coordination around stud rails and PT strands. The MEP coordination process was done in house and then issued to the subcontractors. The subs doing the installation of the systems were new to the 3D BIM coordination process – at times this showed. Though they participated in all coordination meetings and provided useful information to the team in how things would truly be installed, there was still a challenge with quality control and process. Supplemental Documents were provided to these teams in the field by (SIG) and would be utilized on site, whether in the trailer or taped to the walls in the area of work. These documents proved to be useful in assisting those in the field, and all involved, by providing greater clarity. The coordinated field use drawings were then implemented into an official design document. (SIG) provided the backgrounds to which the engineer would later adjust their drawings. The project team was very instrumental in communicating the challenges and resolving them with all parties involved. The process of using the EDM and the Navisworks model simultaneously in the meetings provided an efficient method of documenting and illustrating RFC’s and issues in the field. Working with the Architect, (SIG) was involved in the envelope review. Details were analyzed with product data that was issued to compare the intent of the design with the final buy out. Materials were also analyzed as to how they would connect, ensuring proper protection from water infiltration. Through this process, a design flaw was discovered in a product that was later sent back to the manufacturer to be corrected. Overall, the project was challenging but very rewarding in regards to the coordination. Working together with the design team, (SIG) was able to build a relationship that created a successful project through collaboration. -Joshua Ward Building Systems Coordinator

spring edition
(SIG) Services
Coordination began early with the creation of Concrete Lift Drawings which were utilized in the field to provide a clearer understanding of all self-performed concrete work done by GE Johnson. Coordination of the sleeves and the embed plates were critical on this complex design, as each pour was unique. Graphics were used in the field and in the jobsite trailer to illustrate the wall pours, and the steel erection sequencing. (SIG) led the efforts in MEPF coordination, working with the subcontractors. The team was able to identify and resolve the majority of the clashes before they were installed in the field. While every effort was made to resolve clashes ahead of time, some items required field coordination, while others needed input from the design team. Technology was an integral part of the project. Electronic Document Management (EDM), iPads, Prolog Converge and other tools were utilized throughout the job. Navisworks was part of the daily meetings and useful in communication with owner and project teams. Having a project team on site capable of utilizing the software was a huge asset to the coordination process as well as the overall success of the -Joshua Ward Building Systems Coordinator project and coordination efforts

Envelope Review
“With the Broadmoor being such a fast paced project, having SIG assist and coordinate in preconstruction and during construction was invaluable. During weekly coordination with the subcontractors and designers SIG helped to eliminate the need for producing RFCs, which took a lot of weight off of the project team. SIG helped in coordinating new systems that were being integrated into existing systems, such as MEP, structural, Eggrock pods and elevators. They also helped in identifying errors or discrepancies that were in the design team’s model saving time and problems down the road. ”

Broadmoor West’s 26-week construction schedule greatly benefited from (SIG)’s coordination efforts. (SIG)’s contributions to this project were primarily concentrated on MEPF coordination, but also included a virtual mockup, brief building enclosure review, drawing QA/QC review, roof truss coordination, prefabricated bathroom pod coordination, and concrete lift drawings. MEPF coordination kicked off approximately 2 months prior to construction, and continued for around 5 months. One of the challenges for this project was verifying existing conditions for all MEPF systems, which we were not able to fully verify until demolition began in early November 2013. Even then, asbestos removal slowed the pace of the demolition. All new systems were laid out virtually on existing floors, requiring additional rework in certain areas once existing conditions were verified. 175 prefabricated bathroom pods provided a much easier coordination effort for MEPF connections. A number of precast panels had to be cored to allow mechanical and fire protection routing to pass through. With a model locating all reinforcing and plates for the panels, (SIG) located all locations where coring was required. The initial design called for an exterior pipe chase running up the west face of the building, then across the roof, for connections to the new construction on the upper floors. The project team requested (SIG)’s assistance in determining whether alternate routing, internally, was possible to allow not only for large cost and time savings, but provide for a more aesthetically pleasing look to the building. (SIG) was able to work with the subcontractors and the structural engineer to provide a reroute that worked. PLAN

“The GE Johnson SIG Department was a huge asset on the front end of this project. With their help, we were able to find, coordinate, and resolve several “major” clashes with our MEPF trades. This proved to be a huge time saver and made the installation process and subcontractor install coordination much easier.” -ADAM WINDLER Project engineer

“SIG was instrumental in working with a budget and providing value to the MEP coordination process at the El Paso/Teller County 911 Dispatch Center Addition in Colorado Springs. The design team provided the base model through the construction documents created in Revit. A coordination meeting was held with the architect, engineers, and the MEP subcontractors. SIG located over 80 clashes allowing us to resolve structural conflicts and above ceiling clearance issues months ahead of the scheduled work. The entire team benefited as the architect and engineers were not inundated with RFCs at the time of installation, MEP subcontractors were setup for an efficient rough-in, and the GE Johnson team could plan beyond the rough-in stage and focus on the finishes.” -Jason Berning Superintendant

SIG performed the typical MEPF 3D coordination on the Penrose Cancer Center by engaging the MEPF subcontractors and using their model in the process. One exception was the mechanical sheet metal subcontractor did not have 3D modeling capabilities so SIG performed modeling of the duct work for the coordination efforts on the project. Once these systems where coordinated, SIG created ďŹ eld use drawing to assist the mechanical sheet metal subcontractor in both fabrication and ďŹ eld installation.

3D Revit models were received from the Architect, Structural Engineer, and MEP consultant. SIG compiled these models into a composite model and ran clash detection to determine major constructability issues versus minor ďŹ eld coordination issues. A detailed report of these issues was created and a meeting involving the design team, MEPF subcontractors and GEJCC project team was setup to review the model and the report. The goal of this process was to have one meeting to review all issues and get all major issues on the table for resolution or write RFC’s to get resolution before construction was to begin. To achieve this goal the meeting was held via GoToMeeting/Video conference. This allowed for an interactive meeting for all to see the model and also to be involved in the live discussion. This entire process proved to be valuable in helping both the design team and construction team in correcting issues before they became problems.
