Client Profile.

The client is a UAE-based precast manufacturer/contractor. They serve a global clientele across industries through their wide product range of offsite reinforced concrete structural elements.

Business Need.

The client was working on a large-scale precast project that involved 15,000 precast structural elements. The legacy methods were time consuming and error prone. Often elements were incorrectly cast, leading to increased costs and material wastage. The client hence wanted to transition to BIM technology.

The client collaborated with HitechDigital to get a coordinated 3D BIM precast model at LOD 450:

Challenges.

Achieving high precision levels in such a high scale project invited multiple challenges for the BIP experts. Some of these included:

Solution.

The team at HitechDigital delivered a completely collaborated and clash-free BIM model using the BIM 360 platform to enable seamless communication across stakeholders.  The model was RFI standardized to reduce design ambiguities and identify and resolve scheduling errors of structural elements. The coordinated 3D BIM model at LOD 450 was accompanied by:

Approach.

An initial assessment of the input AutoCAD drawings and PDF files was conducted by a team of 25 experienced structural BIM modelers and detailers. The input documents included site and structural floor plans, building elevations, sections, and related details.

Tools and Technology used- Autodesk Revit, Autodesk Navisworks, AutoCAD, BIM360, Microsoft Excel

Business Impact.

Quality: Improved quality of precast deliverables
Cost: Accurate procurement supported by 3D models with precision of under 5mm for M60 concrete grade enabled zero material waste
Cost: Cost savings due to 100% accuracy of deliverables
Time: Fast TAT of BIM deliverables within 6-8 months which enabled accelerated onsite building erection
