Business Needs: An architectural and engineering firm needed to convert their 2D drawings and sketches into a coordinated and error-free 3D model at LOD 300 for their 4-storey residential building in UAE. The deliverables would support the client with improved visualization of architectural and structural design scope through complete component linking. The information in the architectural 3D models would support construction contractors and suppliers in the early planning and design phases to:

• Visualize and review all disciplines in 3D collectively
• Optimize time and cost
• Coordinate 3D models from other disciplines and vendors to achieve clash-detection and resolution
• Make revisions in real-time within a time frame of 1 month

Challenges

• Drawings, sketches, and other information provided by the client were uncoordinated
• Junctions between various components were poorly detailed
• Facilities were located at impractical locations
• A short time frame of 1-month to produce deliverables with random design revisions

Solution

• A well-coordinated and clash-free architectural, structural, MEP 3D model at LOD 300
• GA drawings including floor layouts, building sections, elevations, and detailed sections
• Coordinated BOQ with accurate quantities across disciplines
• The team at Hitech CADD Services stepped in during the planning and design phase and thoroughly analyzed 2D drawings, PDF files, and reference sketches provided by the client
• 2D inputs were converted to LOD 300 3D Revit models
• Interdisciplinary coordination and clash detection, along with design revisions were performed as per project needs
• Greater emphasis was given on detecting and resolving clashes between various building components to drive enhanced visualization
• Redundant, duplicate, and inconsistent information was removed from drawings to drive higher accuracy and detailed specifications
• This was done using standardized AIA procedures for annotations, symbols, and hatching that led to a clear interpretation of information for multiple disciplines
• Data was stored, accessed, and shared in real-time over BIM360 to resolve ambiguities, gain higher coordination, save time, and reduce material wastage

Business Impact

• 98.5% error-free deliverables
• Quick 4 week Turn Around Time (TAT)
• Detailed model enabled client to improve end-client presentation by using the 3D models to create walkthroughs
• Ease of data access on any device with BIM 360
• Overall project time, cost and material savings
