This residential project was used by HCF and Associates Architects to incorporate a BIM-integrated design process. BIM has not only proved to reduce time and resource use from creation to completion, but it has also had a positive effect on architects’ thinking processes and constructive mindset.
The House 15 project is situated in one of Singapore’s most exclusive gated communities. The building lot is 700 square metres (7553 square feet) and is adjacent to other lots of similar scale.
Despite its importance, the site is relatively small. Restrictive setbacks and height restrictions add to the size constraint.
House 15 is a geometrically inspired architecture with three distinct blocks arranged around a central atrium. The program’s tripartite essence is reflected in the three blocks. It evokes a sense of domesticity while preserving in-between spaces for spatial ‘events’ like spiral stairs, atriums, and lifts.The floor plan is divided in a traditional manner, with public spaces on the first floor and more private spaces in the basement and second floor.
The workflow for this project revolved around decision, execution, and analysis.The project architect gradually introduced layers of data to the BIM model while retaining a high level of versatility to accommodate frequent design changes and adjustments.
The BIM model was organised by HCF and Associates to be as flexible as possible, making it easier to extract model representations and data. The layers, layer combinations, pen sets, model view choices, and overrides were meticulously created, organised, and prioritised to achieve this.
Another important feature of the House 15 BIM concept was to “design the model as it would be constructed in real life.” As a result, the model is an exact virtual reflection of what must be accomplished on the job site. It also aids in identifying several potential problems and clashes at an early stage, enabling them to be resolved well before they have an effect on the construction.
A. Creating rooms with undefined walls and slabs
B. The structure, openings, and ceiling are all completed. Materials for the walls and slabs are defined.
C. The addition of M&E components, finishes, interfaces, and early design intentions
The BIM model’s versatility allows for easy knowledge extraction. A single 1-click action was used to obtain each of the views.
