Problem Statement from the client

The client business model is to lease buildings for long term at prime location, carry out fit out works with all the modern amenities and offer office spaces on ‘Space as Service’ model. With the huge success of the business model and fast growing business, clients had a need to lease, design and occupy properties faster to cater the market requirements ensuring the customer does not walk away to other spaces.

As we were already supporting them for Technical Due Diligence and Developing Existing Condition models, We had a better understanding of the clients requirement and the building condition.

We offered ‘Digital Design & Management’ service for the Design phase of the projects.

Scope of Work

The solution provided to the client was ‘Digital Design Management & Digital Project Management’ which included:

Mobilization

1. Checking the Due Diligence Report to understand the Building
2. Setting up a CDE and BIM Documents as per ISO 19650 Framework
3. Developing the BIM Execution Plan & Design Brief Report

Collaborative Information Production

1. Developing SLD’s
2. 3D Modeling for Civil & Interior - 3D Modeling for Mechanical, Electrical, Plumbing, Fire Protection, FAPA Systems, Access Control, Security Systems and ELV Systems.

Information Delivery Phase

1. Clash detection and coordination
2. Quantity Take-off
3. Drawings Production 

Construction Phase

1. Checking the BIM Docs. developed by subcontractors as per ISO19650 Framework. 
2. Ensure all subcontractors develop construction phase models as per BEP.
3. Checking if the CDE is maintained as per ISO 19650 Framework.
4. Support subcontractors to input Asset information(Non Geometric) information to the BIM model.
5. Digital Handover of the project to Client.

Input Shared by the Client

The inputs shared by the client varied for each building. The list mentioned below are few important piece of information required for Technical due diligence:

• Building layouts.
• Occupancy certificate, Structural stability report, Fire NOC, CEIG Report, & NOC’s from different local and national bodies.
• Design Brief Report(DBR), Technical Data Sheet(TDS) of existing infrastructure.
• Technical Due Diligence Report.
• Site Visit Reports & Site Images.

Software used

• Autodesk Revit
• AutoCAD
• PDF viewer
• 360° photo viewer
• Fieldlens
• Spreadsheets viewer

Project Timeline

The timeline from the day of kick-off to delivery of the GFC drawings to the Contractors was 9 weeks. This included Mobilization, Collaborative Information Production and Information Delivery However we extended our support to the client for coordination and discussing with the developer which would usually close within 2 weeks from the site visit.

Key Challenges & How we solved the problem

‍

Challenge: The major challenges faced was discrepancy between site and layout shared. Either the layouts were older or the As-built did not reflect the site changes.

Solution: While site visit the floor was checked with great attention to identify the variations this would help to decide if Laser Scanning was required. Once the building was leased the building was laser scanned to bring the existing conditions to the Architects desk for error free fitout design.

‍

Challenge: Another greatest challenge was getting the right information from the developer. Due to poor information management, latest information regarding the building was not available with the developer.

Solution: Based on the past experience we drafted out a detailed questionnaire for each trade. For all the missing information the data was either physically collected at site or from the site team with the help of checklists. This reduced the gaps for due diligence.

‍

Challenge: Managing BIM developed information and ensuring only latest information is used at site

Solution: All Subcontractors were mandated information exchange only through CDE and assigned relevant information when sharing with other parties. This would avoid using older versions/ revision of drawings by other stakeholders in the project bringing transparency across all parties involved.

‍

Challenge: Use of BIM Models for Digital Handover to Building Owners & Facility Team

Solution: All the information produced are not limited to only the Design and Construction Phase, But also can be used while the Operations and Management Phase. The BIM with relevant non geometric information can be used directly in various CMMS platforms for managing any facilities.

Outcome or How the client got benefitted

The result here was all the information produced from the Design Phase & Construction Phase were handovered to the Client digitally. The Potential risks were mitigated during the design phase with BIM models. Only the latest information or approved drawings were sent to the site team for construction which avoided reworks and project timelines could be met.
