How BIM successfully tackles a challenging project

Tekla Structures and Trimble technologies enabled Clark Pacific to manage the construction logistic efficiently.

A small job site. A short timeline. A big solution. A tight project timeline proves the value of BIM as Clark Pacific implements an innovative prefabricated construction technique.


In September 2020, Stanford University in Palo Alto, California, opened its newest and largest on-campus housing development to date. This new development, Escondido Village, features housing for over 2,400 graduate students. In total, the complex consists of four residence halls that range from six to ten stories high and increases on-campus graduate housing from 55% of students to at least 75%.

Overcoming unique construction project challenges

Making this project especially challenging were factors such as managing a construction site located in the midst of an active college campus, engineering for the project’s location in a seismically active region, and being respectful of the distinctive architectural heritage of Stanford University.

To successfully complete this project with all of its inherent challenges, an offsite construction method was identified as the optimal solution. With decades of experience in designing, manufacturing, and building prefabricated concrete structures, West Sacramento, California-based firm Clark Pacific was tapped as the design-build contractor for the structural frame of this important project.

Clark Pacific was selected as a winner in the Tekla North America BIM Awards for the precast category. Called out for being “remarkable in BIM-use,” the Clark Pacific design included precast concrete panels with pre-installed glazing, making it possible for the structural frame to be built up faster and for the building envelope to be closed sooner. This resulted in valuable time-savings and risk mitigation for all project parties.

Workflow coordination is key in construction

Asked how BIM improved the project flow, Grant Guerrieri, Senior Project Manager for Clark Pacific, explains, “One of the largest challenges for pre-manufacturing is the logistical considerations. It starts with managing sub-components, the sub-assemblies, and then individual cast units. We sometimes take for granted how complex material logistics can become, but Tekla Structures and other Trimble solutions help simplify these workflows so we can focus on the more value-added items for the client.”

Guerreri notes that model sharing allowed Clark Pacific to expand their workforce globally.

“Clark Pacific has strong partnerships with detailing, structural design, and project management firms in the USA, Canada, and India. Utilizing Tekla Model Sharing allows Clark Pacific to manage our workforce more effectively during the ups and downs of the construction industry.”

This coordination meant aligning efforts across several teams, including Structural Engineer of Record John A. Martin and Associates, Architect Korth Sunseri Hagey, General Contractor Vance Brown, and Detailer Support Pinnacle Infotek. This necessary harmonization of teams was achieved by using Tekla’s BIM technology. 

To minimize miscommunication across contractors, changes flowed between the multiple software tools to meet BIM requirements from the main structural engineer. In addition, BIM data was leveraged for downstream processes as it drove a more accurate and timelier resource planning process.

In construction, innovative tools are vital for success

Clark Pacific’s offsite fabrication process was made even more efficient using BIM information, as rebar production quantities were directly taken to the rebar fabrication solution for mass production.

The Clark Pacific team also aggressively piloted new technologies enabled by Trimble Connect, including sharing IFC’s for individual elements via tablet rather than paper. This made it possible to share and render a more detailed 3D view of the plans than would be possible with traditional paper plans – especially important given the information-dense requirements of this project.

“While all projects benefit from the utilization of BIM, the larger and more complex projects (like Escondido Village) benefit the most. We believe that when you combine the right team with the right tools, the final project cost will be reduced and the product will be better.”

When considering the benefits of the pre-manufacturing construction method used in this project, Guerreri explains that “some of the real-life benefits to the students included noise reduction during construction, speed of construction and less onsite impact.”

The unique solutions put in place to successfully complete the Escondido Village project made the use of BIM technology even more important, as multiple project teams needed to work closely together to implement groundbreaking prefabricated construction techniques. 

For example, the aesthetic and seismic demands of this project meant that the exterior panels were both an integral part of the structure and decorative with complex shapes and reveals. To achieve this, Clark Pacific and architects needed to be fully synchronized throughout – and BIM technology was key to ensuring that synchronization.
