Project Name: AC Naples Marriot, USA

Building Type: Hotel Project

Location: Florida, US

Area: 176,000 SF

Inputs: 2D Pdfs & CADs

Services: Architecture, Structure, Mechanical, Electrical, Plumbing and Fire.

Deliverable: LOD 400 – 3D Models, Clash detection reports and Coordination, Shop drawings and Penetration drawings.

OVERVIEW

The client was MEP Design Consultant working for Contractor. Contractor need LOD 400 Fabrication detail coordinated drawings for construction to reduce rework.
 
The total project area was 176,000 SF. VARMINE had to start this project from scratch, which aimed our team had to work closely with the client’s design engineers to prepare the Fabrication drawings for execution.
 
We began with Architecture and Structural Modelling. Revit software was then used to model the MEP elements. Navisworks Manage and Revizto were used for BIM coordination and clash testing.

CHALLENGES & SOLUTION

A significant challenge was encountered on level 2, where there is very little ceiling space in the corridor area and we have duct, fire mains, plumbing lines, and conduits running above that ceiling. According to the client’s design inputs, the placement of all services was not possible and necessitated more ceiling space.
 
However, we are unable to lower the ceiling height because it is already at a minimum. The main issues are that drainage lines cross the corridors and we need to penetrate the beam at the middle third, which means we can’t change the drainage lines.

 

 

So, first, we fix the drainage position and install sleeves in those beams. Then we begin working on HVAC, changing duct size using CFM calculations, reducing maximum possible height and increasing width while maintaining a 1:3 height-to-width ratio. Following that, we coordinated each service and extracted precise shop drawings and penetration drawings for execution.

CONCLUSION

Change orders are a major cause of project cost increases and delays. In this Project BIM Models assist us in detecting the need for any change orders during the design stage, as well as modifications made virtually in the model rather than physically in the construction. Updating a virtual model is less expensive than disassembling and reassembling actual installations, resulting in lower material and labor costs.

It makes it simple to detect location conflicts between multiple MEP components. If two building systems overlap, the corresponding team is notified. When equipment location conflicts reach the construction phase, they can lead to change orders and project delays. BIM reduces the likelihood of errors and problems on the job site.
