JTC’s CleanTech Two Block B building (CT2B) located within Singapore’s advanced manufacturing hub, Jurong Innovation District, is one of the twelve demonstration projects identified by the Building and Construction Authority (BCA) for its exemplary implementation of Integrated Digital Delivery (IDD).

CT2B achieved significant time and cost savings through employing digital technologies. For instance, Trimble Connect was used to achieve remote centralised monitoring of off-site fabricated components as well as on site installation status.

The IDD Implementation Plan, BCA’s plan for the construction industry, encourages more built environment sector firms to go digital. The plan seeks to digitally integrate the entire built environment value chain to deliver better, smarter outcomes. At each stage of a construction project, ICT technologies, solutions and platforms such as Virtual Design and Construction (VDC) and Building Information Modelling (BIM) are used in IDD to streamline processes and improve collaboration between the different project teams and stakeholders. The benefits of IDD include improving construction efficiency, minimising construction mistakes and costly rework, and the delivery of smarter buildings.

With a total gross floor area of 22,300 sqm, JTC’s five-storey CT2B building hosts state-of-the-art green features such as day lighting and a fully naturally ventilated carpark. Catering to rising industry demand, CT2B provides workshop-like spaces for heavy research and prototyping activities for manufacturing technologies. The building also includes laboratory and office spaces as well as fitted labs for incubators.

The delivery of CT2B demonstrates IDD’s benefits. Its contractor, BHCC Construction Pte Ltd (BHCC), implemented a ‘four-stage digitalisation approach’ through the project’s stages of: design, fabrication, construction and asset delivery and management.

At each stage of the construction project, IDD was used to streamline processes and improve collaboration and coordination between the different project teams and stakeholders.

The project achieved significant time and cost savings through employing digital technologies and digitising formerly manual and time-consuming processes such as:

  • Interactive Design Review using BIM Model and Virtual Reality

  • Digital construction clash detection and dimension accuracy check

  • Single source of truth with common data environment

  • Detailed construction activity planning and tracking via digital lean management tool

  • Model-based cost comparison / site model cost verification

  • Fabricated building components monitoring with centralised system to reflect updated status of fabrication, logistics and installation on-site

  • Drone-based site conditions and construction progress monitoring

  • More immersive Safety Induction Course with 3D simulation video

During the design stage, BHCC achieved 30% time savings by implementing a Virtual Reality (VR) collaboration system. The system allowed project members to collaborate and coordinate designs by merging BIM data into a single model to review, analyse and simulate processes. Potential clashes were detected well in advance and addressed before construction began to maximise productivity and minimise rework.

During the construction stage, BHCC achieved 25% time savings by using a project management platform, which enabled all project members to update on the progress of the project, including the status tracking of precast components. A further 25% time savings will be achieved by BHCC digitalising its management of site safety records.

By adopting a through-the-line IDD approach, the CT2B project reaped numerous benefits to the project teams and stakeholders in terms of time and cost savings, safety and quality.
