3D BIM used for logistics planning around NYC High Line

Hudson Yards is a proposed mixed-use real estate development that will be part of the Hudson Yards Redevelopment Project in Midtown Manhattan, New York City. The development is expected to consist of 16 skyscrapers and is planned to contain over 12,700,000 square feet (1,180,000 m2) of new office, residential, and retail space.

At the southwest corner of West 30th Street and Tenth Avenue, the Related Companies is beginning work on a new 33-story residential tower (rendered below). The contractor was looking to utilize their own hammer head crane at the site, which posed a significant logistical challenge, being that it swung over heavily trafficked areas including the High Line. The Ziggurat team converted the 2D CAD logistics plan into a 3D live model, that included animation of the crane's operation. The model was presented to the NYC DOB's Cranes and Derricks Unit which oversees the design, installation and safe operation of equipment used for hoisting or lifting purposes. The 3D model presentation was a major contribution to the eventual approval to use of this crane, saving the contractor and developers hunderds of thousands of dollars.

Another high-end retrofit project takes advantage of 3D coordination

Dubbed as the "next 15 Central Park West" also developed by Arthur and William Lie Zeckendorf; 18 Gramercy Park also share the same architect, Robert A.M. Stern. A two-bedroom maisonette will start at $9.25 million, the average price is $17.5 million, and the priciest unit will be a five-bedroom duplex penthouse with two outdoor pools and a $42 million asking price. 

The developers and Stern have been working to modify building layouts, formerly a Salvation Army residence. Although the project was designed using traditional 2D CAD methods, the developers decided to implement again advanced 3D BIM process to increase design and construction efficiency.

Many retrofit projects face similar challenges; how to integrate existing conditions with new modern design, while maintaining the integrity and demands of the modern design such as maximizing ceiling heights, dense MEP systems etc. 

Ziggurat was hired by the developers to assist in cellar MEP coordination. Ziggurat converted the 2D MEP Structural, Architectural and existing conditions survey into a 3D BIM model. Once the 3D model was analyzed for design clashes ("hits")  between HVAC systems, existing beams, stairs,  head height requirements, slab penetration and ceiling heights,  multiple deviations were discovered and were resolved during design stage accelerating the coordination process and enable the project to transition to construction phase with fully coordinated set of plans.

Safety engineers use Ziggurat to convert 2D safety plans to 3D models for fast approval by NYC DOB

The New York City Department of Buildings recently unveiled a safety initiative that encourages contractors to submit 3D/BIM site safety plans. The initiative makes the City’s Building Department one of the first to accept and review safety plans in this manner. 

The Department’s new 3D Site Safety Plans program uses Building Information Modeling (BIM) software to create and electronically file site safety plans. The program enables the Department to virtually tour sites and see step-by-step how a building will be built and visualize its complexities and challenges. Under the program, site safety plans are digitally submitted, amended and reviewed, improving the compliance review process and accelerating the approval process like never before.

With Ziggurat plug-in for AutoCAD, any 2D CAD plan can be quickly and easily converted to 3D model to comply with NYC DOB requirements. The Benefits of 3D Site Safety Modeling include:

  • Increased Site Safety: Safety risks can be identified early in the process before issues arise in the field
  • Faster Approvals: Three-dimensional, real-time images enhance communication between field inspectors and office supervisors, helping them resolve issues immediately
  • Better Service + Fewer Office Visits: Site safety plans submitted through this program will be reviewed, modified and approved – all through the online document management website

Autodesk® endorses our solution to convert 2D plans to 3D models for BIM coordination

This endorsement to our solution from Autodesk has been around for some time and it is even more valid now that there are so many more projects that require 3D BIM coordination, but the lack of skills and expertise in the field prevails, and too few contractors can comply with the basic task of developing and coordinating the construction phase in 3D BIM. The folks at Autodesk provide a very good endorsement for our solution. Read more

Ziggurat to lead the BIM coordination during construction of DASNY's first BIM project

Building Information Modeling (BIM) is becoming the standard for delivering healthcare design projects. The Dormitory Authority of the State of New York (DASNY) is among the agencies to have recently released standards requiring the use of BIM. DASNY and the New York State Office of Mental Health (NYSOMH) and the Bronx Psychiatric Center are in the process of development of a new campus master plan encompassing six new buildings on 50-plus acres, as well as the preservation of five existing buildings. This will be DASNY’s first BIM project.  

Ziggurat was retained by the General Contractor who will perform the work to lead the BIM coordination process on the new $350 million medical campus at 1500 Waters Place in the Bronx.

First 3D BIM coordination for Ziggurat in Sao Paulo, Brazil

This is a fairly simple project in terms of engineering and construction, however, we decided to write a blog post on it since it is the first 3D BIM project our Brazilian partners engaged in; a residential building, consisting of five floors in Sau Paulo.

The architect and engineers designed the building using AutoCAD 2D and the local Ziggurat team in Sao Paulo converted the design documents into a 3D BIM model using Ziggurat 2D to 3D plug-in for AutoCAD. They continued with clash detection analysis using Ziggurat's Navisworks plug-in and supported the coordination process, enabling the architects and engineers deliver a clash-free design.

This is a classic case where designers and engineers are using their familiar 2D  design application, yet enjoy the full benefits of 3D BIM coordination in a simple and easy implementation model. They can view their 2D designs, side by side with the 3D BIM that was converted from their AutoCAD files.

Facility management of a luxury hotel takes a leap into 3D BIM with Ziggurat

A luxury hotel in New York City was looking to improve their facility management and maintenance processes, which were based on 2D CAD “as-builts”. Their choice was a solution based on Ziggurat. We converted existing 2D AutoCAD as-builts into a 3D model utilizing Ziggurat’s plug in for AutoCAD and Navisworks.

Once conversion process is completed, as shown below,  facility managers are able to access any location in their facility virtually without the need to master AutCAD software. The Ziggurat Management dashboard allows the facility manager to access their asset, space, and technical information on the 2D drawings and the 3D model side-by-side on Ziggurat 2D/3D viewer. Other key benefits include:

  • Retrofits and Renovations  - 2D AutoCAD plans converted into 3D models can be used by architects, engineers and contractors in future renovations for more efficient build outs, remodeling and retrofits (i.e., in communicating 3D spatial information, in performing clash detection and in displaying 3D network information).
  • Space Management - 3D models offer complete visibility into space and access to remote occupancy data, thereby assisting owners in better understanding their asset and to better communicate information for leasing purposes. Better visualization improves communication and collaboration between stakeholders as the building evolves.

Leading shopping mall developers implement 3D BIM coordination with Ziggurat

Azrieli group of companies is one of the Middle East’s leading owners of income-producing properties (shopping malls and offices). The group owns leasable area totaling approx. 653,000 m2 (6,835,000 sq ft) and approx. 328,500 m2 (3,498,000 sq ft) under construction. The company wholly owns thirteen shopping malls.

 Ziggurat was retained by the group to convert 2D plans into 3D BIM models and coordinate in 3D more than 10 malls, of varying sizes. Few of the coordination challenges facing designers when planning and building a shopping mall are:

  • Allocate minimum volume for mechanical systems installed in open spaces.
  • Routing mechanical systems around stores so as to maximize store heights and volume.

 Ziggurat converted the design and construction documents from 2D into 3D using our AutoCAD® plug-in and utilized Navisworks® for clash detection and Ziggurat’s Navisworks plug-in to conduct the 3D BIM coordination process. Below are 2D-3D side by side images from our viewer.
