Coordinated and clash-free architectural and MEP BIM models speed up installation of utilities at national park in the USA

BIM Model for Public Park

BIM LOD 300 for Park

BIM Clash Detection

Challenges.

One of the key challenges of the project was its time sensitivity given the tender deadlines. The Hitech team needed to complete the project within a short duration of six weeks trying to navigate the following constraints:

• Incomplete as-built documentation for park area
• Need to fit in voluminous mechanical, electrical and plumbing systems through a maze of existing MEP components.

Solution.

Hitech’s BIM team delivered a composite package of architectural and MEP BIM solutions models to facilitate harmonious installation of new utility systems in the national park. The deliverables included:

• An information-rich architectural model at LOD 300 of new garden area
• HD renderings of the architectural model
• Revit families of BIM objects for the site
• Clash-free coordinated 3D MEP model (along with clash detection reports using Navisworks)

Approach.

A team of 10 BIM modelers initially studied input drawings and requirements sent by the client and documented scope of work.

• The team first created terrain models with the given contour points based on CAD drawings of terrain.
• These models were then imported to Revit to create 3D architectural models of existing site, structure and systems.
• They next created a 3D MEP model with precise layout and services as per the proposed designs.
• The MEP and architectural models were then coordinated with existing connections and services to help avoid interferences.
• Clash detection reports were generated using Navisworks; any clashes between the existing and new MEP systems were identified and resolved.
• Once the model was approved by the client, the BIM experts also created Revit families of BIM objects. Complex structures, which could not be modelled using Revit family were developed using Rhino. Once a Revit family was created using the Rhino file, it was then placed into the Revit Model.
• The team also delivered HD renderings of the project for better visualization and client presentation.
