PDF/CAD to BIM conversion & construction drawings for a dental clinic in Kentfield

Overview

The Tenant Improvement Project aimed at transforming an existing medical office building into a modern, efficient, and fully compliant clinical environment. The key objective was to integrate sustainable design measures and improve patient comfort and functional layout.

Therefore, the core tasks included:

Reconfiguring interior spaces and upgrading building systems (electrical, HVAC, plumbing, lighting, medical gas, etc.);
Enhancing finishes and millwork to meet current operational needs;
Complying with CBC, CALGreen, ADA, and all local regulatory requirements.

Throughout the project, special attention was given to sustainable design measures, including low-flow plumbing fixtures, energy-efficient lighting, and material compliance with CALGreen standards. These measures were integrated to reduce environmental impact and improve long-term operational efficiency, all while supporting a healthier and more comfortable environment for occupants.

Scope of work

Selective demolition;
Construction of new partition walls;
Upgraded finishes;
Cabinetry and millwork;
New flooring and ceiling systems;
Installation of new electrical, lighting, HVAC, plumbing, and medical gas systems.

Input:

Point cloud survey of the existing medical office building;
Google Maps site context;
CAD proposed plan;
Excel schedules with information on interior finishes and plumbing elements.

Project deliverables:

Coordinated Revit 3D model and full architectural drawing set.

Existing model creation from point cloud data

At the outset, we received a point cloud survey of the existing building and used it as the basis for creating a precise 3D as-built model. The model was developed to accurately reflect existing conditions and serve as the foundation for subsequent design and documentation.

Additionally, the site plan was drafted using Google Maps to provide contextual information about the building and its surroundings.

From CAD to BIM

At this stage, DWG documentation of the proposed plans was converted into a BIM model to enable coordination and design development. By transforming the CAD drawings into a BIM model, we ensured accurate geometry, seamless coordination, and clear visualization of the proposed design.

As a result, all project participants received a coordinated and reliable model that supported design development, documentation, and smooth collaboration.

Developing a full set of architectural plans and details

Next, a developed Revit architecture template was applied to ensure consistency and efficiency across the project. This allowed us to get predefined settings: view templates, sheet layouts, title blocks, schedules, annotation styles, etc.

By working within this unified Revit structural template, the ORIGIN team was able to accelerate documentation production and reduce errors along the way.

RFI management & project coordination

During the project, the team successfully coordinated all key issues and resolved technical challenges.

In particular, ORIGIN experts paid special attention to the following aspects:

ADA compliance;
Parking layout optimization;
Integration of technical elements (f.e., lifts, lighting, etc).

Through precise 3D modeling and effective coordination, ORIGIN carefully managed all the updates to the layout, lighting, and door elements. The team also adapted the design to existing structural conditions and spatial constraints.

Coordinating interior finishes and plumbing elements

Additionally, ORIGIN experts delivered a detailed finish plan with a clear distribution of flooring, wall, and ceiling materials according to room functions.

To ensure precision and consistency, selected areas of existing wood paneling were preserved and integrated into the new design. Plumbing fixtures (such as sinks, toilets, emergency, and hygiene stations) were also specified to be water-efficient and compliant with modern standards. Our team also ensured that all elements fit seamlessly into the overall interior aesthetics.

Final revisions

In the final stage, our team carefully incorporated all revisions into the architectural set, including approved finishes, RFI responses, client comments, Building Department requirements, and other updates.

By systematically updating the documentation, we ensured that every detail aligned with the latest design intent. This high level of consistency, in turn, helped minimize potential issues during construction.
