Community College of Rhode Island
This project started life as a traditional 2D design and was converted to 3D / BIM for the purpose of analyzing conflicts and demonstrating various schedules in a 4D environment. The process started by obtaining 2D CAD data from the architect and using it as the primary geometry control in both Revit and SolidWorks modeling applications. Revit was used for the majority of architectural and structural elements while SolidWorks was chosen to do some higher level detail modeling in the roofing system and to supplement the MEP systems. The models were later joined in Navisworks where they were analyzed. The analysis included a full clash report of intersecting volumes along with multiple 4D runs using various configurations of the same Primavera CPM schedule. |

University Law School – Pennsylvania
A/E/C Strategy is currently assisting the construction manager for a universitys new law school to prepare a BIM model for design and construction coordination. The 103,000 SF facility was designed by architects using traditional 2-D CAD tools. A/E/C Strategy is converting a majority of the architectural elements to 3D using Revit Architecture 2008, including all partition walls, masonry walls and exterior masonry walls and cladding, doors, windows, and acoustical and gypboard ceilings. The full master model is being coordinated in Navisworks Jetstream V5. To date, the basement level modeling and coordination has been substantially completed. It is anticipated that a 4D model of the facility will be developed for construction sequence and schedule management. In addition, an as-built model will be attributed with major equipment and systems data to be utilized by the university facilities management group. A/E/C Strategy is acting as a technical resource to Gilbane and will participate and assist the CM through the entire modeling and virtual construction process. |

NFL Football Stadium – Michigan
A/E/C Strategy provided expert consulting services to the project architect/engineer and its counsel in evaluating claims asserted by the construction contractor. As part of this role, we assisted the structural steel experts in demonstrating the fallacy of the claimant’s allegation of “un-constructible steel connection concepts” for the stadium’s long-span steel roof support system. A/E/C Strategy developed a 3D model of the connection concept that was included in the contract documents in order to successively prove their validity to the arbitration panel.

Central Artery / Tunnel Project: Vent Building One – Massachusetts
A general contractor suffered a differing site condition relating to the project’s available work site. To demonstrate these owner related impacts to the schedule, a 4D model was prepared. The 3D item resolution was kept relatively low meaning only the concrete and steel was modeled and then linked to the contract CPM schedule. The construction process was then simulated against time using the approved baseline schedule and a second time using the last available monthly update schedule. The 4D presentation became the “common page” for all the contractor’s key issues during a formal DRB process. |

Metro West Water Supply Tunnel – Massachusetts
A detailed model was prepared at the request of a prominent heavy civil contractor to analyze their means and methods for future work. The task was to remove the main beam of a tunnel boring machine (TBM) upon completion of a 6 mile, hard rock drive. Two shafts were available to the contractor for removal. One was a larger diameter construction shaft miles away from the machine and a second one was a smaller diameter raise bore shaft located near by. The model was analyzed dynamically to simulate the process of removal and to obtain tolerances at key points along the path. The result from the effort directly influenced the contractor’s final methods. |

Post-Tensioned Viaduct Construction – Massachusetts
A general contractor engaged in construction of a post-tensioned concreted viaduct roadway in a busy international airport retained A/E/C Strategy. Numerous design issues had delayed the project and impacted the construction sequence. A decision was made by the general contractor and its counsel to develop a highly detailed 3D model of a particular end beam for the purpose of graphically demonstrating one of the more severe constructability issues on the project. All embedded elements were modeled including: tendons, anchor heads, reinforcing steel and electrical conduit. Clash detection was used to flag all intersecting volumes. |
