Property Leasing and Occupancy

Problem Statement from the client

  • The client business model is to lease buildings for the long term at prime locations, carry out fit-out works with all the modern amenities, and offer office spaces on the ‘Space as Service’ model. With the massive success of the business model and fast-growing business, clients needed to lease, design and occupy properties faster to cater to the market requirements ensuring the customer does not walk away to other spaces.
  • As we were already supporting them with Technical Due Diligence and Developing Existing Condition models, we better understood the client's 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:

1. Mobilization

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

2. Collaborative Information Production

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

3.Information Delivery Phase

  • Clash detection and coordination
  • Quantity Take-off
  • Drawings Production

4. Construction Phase

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

Input shared by the client

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

  • Building layouts.
  • Occupancy certificate, Structural stability report, Fire NOC, CEIG Report, & NOCs 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.

  • PDF viewer
  • 360° photo viewer
  • Fielden's/BIM 360° Docs
  • Spreadsheets viewer

Project Timeline

The timeline from the day of kick-off to the delivery of the GFC drawings to the Contractors was 9 weeks. This included Mobilization, Collaborative Information Production, and Information Delivery.

Key Challenges & How we solved the problem

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

  • Solution: While the site visits 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 fit-out design.

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

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

Managing BIM-developed information and ensuring only the latest information is used at the 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.

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

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

Outcome or how the client got benefitted

The result here was all the information produced from the Design Phase & Construction Phase was handover 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..
