Recently, WDI Studios has been working on this BIM Coordination and documentation project partnering with our alliance in Singapore.

cable trays - Electrical BIM

For this BIM Project, we have worked in conjunction with a well renowned Japanese Contractor for a R&D Facility and  manufacturing unit in Singapore. As a BIM or Building Information Modeling service provider, we were required to model the state-of-the art electrical services for this R&D facility.

Electrical services modeling can be tedious and time consuming as it covers almost more than 5 types of systems within itself. These distinct systems can be categorized as Cable Containment, Power, Lighting, Lightning, and Security systems, etc. And no doubt, being the Japanese into the play, these electrical systems were to be state of the art product line.

The electrical systems are installed such that high security be the key point of consideration. There are independent cable containment systems for each type of electrical systems which forms a complex network of cable trays in the project. As we were familiar with the efficient space planning for a factory based in Malaysia, we used the the same expertise to successfully route the cable trays avoiding clashes with each other and with other systems.

For the BIM part, we handled design management, design drafting, coordination, and shop drawing production for the project.

Project Details

Located within the Jurong Innovation District (JID), the US$150 million investment is its first manufacturing center and R&D Hub outside of Japan, expected to open in September 2018.

The new building will have four storeys with a floor area of 33000 square meters, on the land of about 18,000 square meters. One of the reason Singapore was chosen is due to its strategically-located geographical position.

Software/ BIM Tools

BIM tools used

  1. Autodesk Revit  2017 – For BIM modelling/authoring and 2D Shop Drawing extraction.
  2. Autodesk Navisworks Manage 2017 – For Clash Detection and Clash Management.

BIM Collaboration and Communication Strategy

Collaboration Procedures

The Collaboration and Communication for the project was done primarily with the use of the BIM Construction Model. Any model/data exchanges from Model users were required to be minimum and were done in Autodesk Revit 2017 (.rvt), whereas in Autodesk Navisworks, new model updates were analyzed.

The BIM model was used as a tool for discussion during various BIM meetings and Design Technical/ Coordination meetings to visually help to see discrepancies or missing information on the project building. For the transparent communication and strategic planning in the construction stage, 4D BIM Construction Sequencing was prepared and Construction Progress was recorded and compared to highlight the progress and milestone of construction. 

BIM Model and As-Built BIM Model Development Process

The following process was defined for the BIM Construction Model and the As-Built BIM Model.

BIM Model Quality Control Checks

QA/QC processes are to ensure that project teams are using best practices in the development and file exchange of BIM models and facility data. That was an ongoing process, which was conducted by the BIM project team and validated by the BIM manager/Assistant BIM manager at both project milestones and at random intervals to ensure that each model is being constructed in accordance with the BIM Standards and is suitably modeled for its intended use.

 Visual Check : To ensure that there are no unintended model components and the design intent has been followed.

Standard Check : To ensure that the BIM Standards outlined have been followed.

Duplicate Check : To ensure that all BIM model elements have been identified and have not been duplicated.

Clash Check : To detect problems in the model where two building components area clashing including soft and hard clashes.
