NYC School Construction Authority implements 3D BIM coordination in a Michael Graves designed school

To meet the current New York City Capital Plan for Schools, the New York City Schools Construction Authority has commissioned Michael Graves & Associates to design a new primary school, PS290 in Queens. To meet the current and projected needs for the surrounding community, the proposed facility will accommodate an adjusted student capacity of 616 in grades PK through 5. The project accommodates approximately 99,000 SF in 5 full floors above grade and one partial cellar.

The NYC SCA, in its first foray into implementation of 3D BIM in its projects, retained Ziggurat to convert the 2D plans into a 3D coordination model and support the coordination process with 3D clash detection during design development stage.

Our team utilized our plug in for AutoCAD® to convert the 2D architectural, structural, mechanical, electrical and plumbing systems plans into a 3D model. Once the models were ready, we ran clash detection analysis in Navisworks®. Integrating Ziggurat in the process, enabled the design team to continue using their preferred 2D design applications, yet take advantage of the powerful 3D clash detection capabilities offered by Navisworks® ; best of all worlds.

Furthermore, the coordination process was supported by our plug in for Navisworks, which allows 2D/3D side by side view of the plans and clashes.

3D BIM coordination at a retrofit of Sterling and Francine Clark museum

Sterling and Francine Clark situated their art museum within walking distance of the Williams College on March 14, 1950.

In 2001, a master plan developed by Cooper, Robertson & Partners dramatically reconceived the Clark campus. Pritzker Prize-winning architect Tadao Ando and landscape architects Reed Hilderbrand Associates were selected. In summer 2010 work began on the infrastructure for the next phase of the project, the construction and renovation of the main campus buildings and grounds. 

The project team included:

Design Architect - VECC
Tadao Ando Architect and Associates, Osaka, Japan

Design Architect – original museum building and Manton Research Center
Annabelle Selldorf, Selldorf Architects, New York, New York

Landscape Architect
Gary Hilderbrand, Reed Hilderbrand Associates, Watertown, Massachusetts

Architect of Record
Gensler, New York, New York

Construction Manager
Turner Construction Company, Albany, New York

And Ziggurat providing 3D modeling, clash detection and coordination services.

Ziggurat joined the team during early design phase to convert all architectural, structural and MEP 2D plans to 3D models utilizing Ziggurat’s plug-in for AutoCAD and Navisworks.

Review of the 3D models helped identify major design issues including insufficient plenum height to accommodate MEP systems, conflicts  with concrete joists and mismatches between architectural, structural and MEP designs such as stairs, slabs, walls and opening shown on different location for each discipline.

These issues were resolved during Construction Documents stage and Ziggurat submitted a 100% CD clash free 3D model that was submitted to the subs for construction.

Norman Foster's Sperone Westwater Gallery in the Bowery

The Sperone Westwater gallery on the Bowery in NYC, designed by Norman Foster has a room-sized elevator shuttling up and down the facade, Ziggurat was retained by the design/build group to bring the benefits of 3D BIM coordination to this demanding project by leveraging Ziggurat’s plug in for AutoCAD® and Navisworks®.

 The so-called “moving room” at Sperone Westwater is a major element at the eight-story gallery and office jimmied onto a 25-by-100-foot building footprint.

 Foster, recalling the early days of design, said, “Any approach we took was hopelessly compromised by the constraints of a 25-foot-wide slot for showing contemporary art and the need to move that big art around. It was like banging your head on the wall trying to figure it out. But once we realized the freight elevator didn’t have to be just for moving crates, but could be used to show art, sculpture, installations, whatever, there was a Eureka moment. And that became the dynamic for the facade.”[1]

 Ziggurat started working on this small but complicated and unique project at the design phase. The challenge was packing all the MEP systems in small riser area and tight ceiling plenum.  During space management phase we identified spaces that needed to be enlarged and drove design changes to accommodate the MEP systems.

 The Ziggurat team utilized the plug-ins to continuously convert 2D plans into 3D BIM models that were analyzed for clash detection and coordination.  The conversion process, which started with the architecture and engineering plans, continued through the shop drawing phase when weekly coordination meeting took place. During shop drawings coordination, the subcontractors submitted updated plans, which were converted and analyzed on weekly basis.

NYC Grand Central Terminal renovations takes advantage of 3D coordination

F.J Sciame construction company teamed with Beyer Blinder Belle Architects and planners in a design/build project to convert existing and unused space in NYC Grand Central Terminal into MTA employees' facilities.  The design/build team, planning in 2D approached Ziggurat to implement 3D BIM coordination of the tight space and brought us on board at 30% CD stage.

As a first step the Ziggurat team converted the 2D plans of the MEP, Structural and existing conditions into a Navisworks compatible 3D model. Upon completion of modelling, initial analysis focused on space management and clearance issues took place to highlight potential conflict between new and existing steel and new mechanical systems.

Reflected ceiling was to be installed tight under new wide steel beams so all crossings were to be done through the beams and all penetrations were to be sized and located at a very early stage. Utilizing Ziggurat's model an inventory report of all elements that need to cross these beams was established.

The project's architects and engineers were instructed on how to utilize the Ziggurat viewer so they could view and evaluate their 2D design in 3D. Sub contractors produced shop drawings when all major issues were resolved and trades moved onto installation without incurring coordination problems.

St. Patrick's cathedral restoration utilizes 3D BIM

The restoration of St. Patrick’s Cathedral in New York City is taking place in three major phases –working west to east –beginning with work on the Fifth Avenue Façade & Nave (Phase I), followed by work in the Transept (Phase II) and then work on the Altar and the Lady Chapel. Each of these three phases includes the restoration of the Cathedral’s exterior, interior and stained glass.

Ziggurat was retained for the work on the new geothermal mechanical plant. Our team utilized 2D site survey and 2D plans for the new mechanical plant to develop a 3D model of existing conditions of the cathedral and check interferences with the newly designed mechanical plant. All 2D plans were converted using Ziggurat’s plug-ins into a Navisworks® compatible model.

3D coordination and BIM for high rise steel tower

The Bow is a 1.7 million sq ft office building currently under construction for the headquaters of EnCana Corp in Calgary, Canada. At 775 ft and 58 storeys in height, The Bow qualifies as a very tall building. Its most innovative characteristic is the steel structure which girds the tower.

Ziggurat was retained by Cosentini Assoc to assist in modeling and coordinating in 3D BIM the mechanical level which consists of numerous systems to be installed within a complex steel framing system. The challenge was to maintain required clearance for plumbing system's gravity pipes and identify exact locations for steel framing pentrations before they get to the field.

Each penetration had to be identified measured and detailed – every elevation was required. After converting the 2D design documents into 3D models using our technology, Ziggurat performed clash detection analysis between steel framing and plumbing system and together with the Cosentini team determined exact location for each penetration, on the drawings board, or rather on the 3D model.

NYC landmark building goes through complete rehab and uses 3D BIM

The Bard Graduate Center: Decorative Arts, Design History, Material Culture, is a graduate research institute of Bard College that opened in New York City in 1993. The existing town house at 38 West 86th Street was reonvated to combine what had been two adjacent buildings at numbers 36 and 38. The BGC’s buildings are situated in a designated landmark neighborhood, therefore, the existing structure -wooden joists (see image) and facades remained.  

Ziggurat was reained during early design phase and converted the 2D design documents, survey drawings, field visits reports and new architectural layout into a 3D coordination model. The project team was able to assess feasibility of mechanical spaces and systems' layout versus surveys of existing conditions. 

Once the construction documents were fully coordinated, the team required the trades to develop 2D shop drawings. Ziggurat converted the shop drawings into a 3D BIM and supported the shop drawings' coordination process. As a result, MEP systems' installation were clean of coordination issues and had zero field generated change orders.
