LEED project benefits from 3D modeling and coordination

Ziggurat was retained by Misltein / Roseland properties to convert the project's 2D design files into a 3D coordination  model and perform clash detection, space management and coordination on this LEED project at Battery Park sites 23/24 in lower Manhattan. As part of the process our team continuously updated the 3D based on updated maed by the project's designers to the construction documents' 2D files and participated in weekly design meetings.

Early space management analysis of the model identified several corridors overloaded with ducts and pipes that had to be averted. The clash detection analysis assisted in early re-routing of ducts and pipes to avoid concrete beams and the over loaded corridors. A mis-placed fuel tank was moved to avoid major conflict with a concrete beam. Below you can see several images from the project as viewed on Ziggurat's 2D/3D viewer - the bubbles highlight clashes that can also be seen on the 2D documents.

3D coordination and modeling for "houses stacked in the sky"

"Houses stacked in the sky" is how Herzog & De Meuron, the swiss architects described this Alexico sky scraper. The 58 story building is set to be built in Tribeca, NYC. Ziggurat was retained by the developer to support the design process by converting the 2D design plans into 3D models and performing clash detection  and space management analysis. We utilized our plug in to convert the 2D structural plans into a 3D coordination model . The goal was to identify required openning for MEP systems in the shearwalls. Early analysis assisted the design team to review their design plans in 2D and in 3D and make informed decisions regarding the exact locations and elevations of these opennings. 56_Leonard_-_structural_model

High end condominium benefits from 3D coordination

Zeckendorf Development, the high end NYC developers behind 15 Central Park West, retained Ziggurat services to support their design team with 3D coordination, clash detection and space management on the luxury condominuim known as 10 UN Plaza. The first task was to convert the 2D design documents, using our proprietary AutoCad  plug-in into a 3D coordination model. Once the model was established, we ran space management analysis to verify that ceilings heights can be maintained as planned, and contain all MEP systems. Initial analysis identified several clashes and limitations which were resolved, on the drawing board. Mainly HVAC duct sizes were changed and re-routed to avoid clashes with concrete beams (image below) and drains were re-routed (see image below).

3D coordination at an affordable housing project in Harlem

The "5th on the Park" is a mixed-use project with affodable housing units in New York City's Harlem. The project presented several challenges to the development team. The architects and engineers designed the project using common 2D software applications, and the building was to be erected above an active church. Building above a gathering place meant that there were no columns, and therefore the structure included massive link beams which can be seen in the images below. The beams were supposed to transfer the residential building load onto the church's perimeter walls. 

The link beams' floor was designed to be the mechanical level, containing equipment serving the entire building. One important goal was to minimize and/or avoid any drilling in the massive beams, and ensure all system fit well into available space - therefore accurate coordination  of systems was key to success of this project. 

we converted succesfully all the designers' files into a 3D coordination model and led the coordination process successfully, which means all systems fit into the space, without field generated change orders and unaplnned drilling on beams.

3D coordination for a retrofit of Madison Square Garden

We were asked to develop a 3D coordination model for a major retrofit project of a famous urban sports arena. The new design presented many challenges, one of which was that the project team had no access to accurate "as-builts" and the new project required installation of major electrical conduits, across several sections of the buildings, including this high-density corridor packed with duct work and piping systems. The solution started from 3D laser scanning to establish existing conditions. Once a point cloud model was created we converted the 2D system design files into a 3D model and were able to identify the ideal route for the new conduits and electrical systems, before a single worker arrived at the site. What you see below is how, utilizing Ziggurat 3D modeling and coordination, we were able to identify the ideal, clash free route for the new conduit and avoid days of wastful "trial and error" in the field.msg

3D Coordination for an affordable housing project in NYC

A leading developer/builder/operator of affordable housing in New York City retained our services to perform 3D coordination of the construction document phase, and develop and coordinate in 3D the shop drawings for the project. This is the second project we do with this client, and the first time they retained us to develop 3D Coordinated shop drawings. 

The reason why we were retained to develop shop drawings, was that this developer typically employ non-union sub contractors, who are not in a position to develop and coordinate 3D shop drawings. The developer was looking to "go to bid" with coordinated shop drawings and eliminate any field generated change orders and delays.

Early on the owner and us realised the benefits emanting from this approach:

Upon preliminary space management analysis it was clear that the vehicle lifts were not going to "fit" into the space allocated. Both mechanical systems and slab and beam configuration were in the way. We worked with the project design team to identify the "right path" for the mechanical system by running clearance analysis which identified potential obstructions for the lifts. 

We also produced 2D cross sections to help the process of problem solving and redesign. (image 2 below). The side-by-side 2D and 3D view of the project was extremely helpful to the team in understanding the problems at hand, and quickly find a solution.

3D Coordination for Sub Contractors

Typically we are hired by the developer, owner or the design/build entity. Recently we noticed a trend where sub-contractors are required to design, coordinate and submit their shop drawings in 3D, and approach us to fill in the gap. We just completed work on a project representing a leading plumbing sub-contractor who was hired to install the plumbing at a ground up project for an ivy league university in Manhattan. The shop drawings coordination process between the sub-contractors was run under a very tight schedule, as the first concrete pour was already around the corner.

The shop drawings included detailed information regarding the hangers, fittings, valves and traps. The 2D darwings were converted using our technology into a 3D model and clash detection analysis was performed versus other trades' models as soon as the models were ready. The clash-free model was later used frequently in the field, with our help to address installation questions.

Why early and continuous 3D coordination saves money

We created a 3D model for a major NYC developer's new project. Initially we modeled the mechanical level, from the 2D drawings we were given access to and then performed clash detection and space management analysis. 

Preliminary space management analysis found that insufficient space was allocated for MEP systems which leads to a major problem with head room – under 7’ clearance in the corridor which will end up significantly lower once systems are installed. 

Early and continuous analysis of the project's 3D  model will guarantee identification of such problems quickly and efficiently and by so shorten design and coordination time. It will also ensure that the developer will eventually have a set of guarunteed coordinated drawings with optimized space allocation. The developer will avoid dealing with redesign which typically becomes significantly slower and costly as project design prgresses.
