Large school extension and redevelopment project. Commenced on site February 2016.
How BIM added value to the project:
Assisted with stakeholder participation through images and Virtual Reality demonstrations. Helped with planning of sequencing of the works. On such a complex building BIM ensured that the construction documentation was coordinated.
Specific BIM tools:
We used software extensions to freely distribute 3d Virtual Reality models to stakeholders allowing fully interactive game type walkthroughs. These were compatible with Desktop computers, tablets and smartphones.
Maintained the as existing and proposed data in the same model allowing us to jump between existing and proposed. This also simplified the process of maintaining data up to date as more detailed survey data was input to the model.
‘Data Drops’ at project stages:
3/D: 3D publicity images; 3D VR models to describe the works to School staff. All planning drawings. Schedules of accommodation, we tailored the reports from the BIM software to generate a set of accommodation reports in the format requested by the Department of Education for stage 3/D.
4/FG: Schedules of accommodation, we tailored the reports from the BIM software to generate a set of accommodation reports in the format requested by the Department of Education for stage 4/FG. Construction Sequencing, we generated drawings and video from the BIM model to describe the sequencing and phasing of works on this complex site which is to continue to function over the course of the works.
Full working drawings including general arrangement, details, window, door and finishes schedules. All data linked to the model and updating from the BIM model.
Quantities extraction: We prepared queries and reports in our software to allow extraction of reports and schedules for completion of BREEAM materials assessments.
Coordination/Working with others:
Doherty Architects developed a full 3D model of the building proposals together with a model of the existing facilities. We set up systems to allow us to take advantage of the model while working with other consultants not yet using BIM.
Structural Coordination: We linked the structural drawings into our 3D model to check for coordination.
M&E Coordination: Room plans with Elevations which automatically updated from the model were produced for each educational space. M&E drawings were produced as an overlay to these with mechanical and electrical components described in plan and elevation facilitating easy checking and coordination.
