McCarthy Building Companies proactively led collaborative sessions with university representatives, architects, engineers and subcontractors, to ensure that ongoing changes to the building minimally impacted the overall project cost and schedule.
Two key challenges were how to deal with worst-case scenarios involving weather, especially desert winds. Another was determining how to create a flexible and adaptable space that fulfilled the needs of future researchers in terms of space, utilities, and configuration.
As an example, to accommodate a research group with highly specialized needs, the third floor of the facility faced significant changes during construction. The project team worked to creatively navigate the delay using Building Information Modeling (BIM) technology to make real-time modifications to the mechanical systems that re-sequenced and expedited the work, cutting what should have been a 10-week delay in half.
A small exterior mockup was built on site using building materials, then subjected to worst-case scenarios of wind, water and smoke to allow testing for deficiencies and ensuring energy efficiency. Another mockup of an interior lab space was created to help researchers determine placement of their typical features such as outlets
The X-ray laser vaults in the basement needed to be magnetically neutral in order to not affect the laser and the research occurring in that space. The challenge with this is that the rebar in the concrete walls and the steel plate that was being added to the headwall of the vault for radiation protection had magnetic properties that would hinder this requirement. The original design called for stainless steel rebar to be used in place of the typical rebar and steel which resulted in over $1 million worth of scope being added to the project.
The construction team worked with the end user for this space and researched a method of demagnetization called degaussing. The construction team was able to sort and degauss — or demagnetize — all of the steel prior to being placed in the vault concrete walls, floor and ceiling. Additionally, the team degaussed the eight inches of steel plate that was added at the headwall of the vault required for radiation protection. Each piece of rebar was individually metered using a gauss meter and all “hot” or very magnetic rebar was removed from the install and or was degaussed. Following the installation of the rebar and steel plates the construction team surveyed the area with the end user’s team to confirm that the area was in fact magnetically acceptable for their sensitive equipment.
This innovation resulted in saving over $1 million for the project that was ultimately added back into the project as added scope. The space passed all degaussing tests and is currently being occupied by the research team.
The ASU Biodesign Institute C research lab was programmed and designed to be a universal lab which could accommodate many different types of research without significant changes being made to the project. This requirement was due to ASU not currently being aware of the researchers that would be occupying the space or the type of research those principle investigators would be conducting. ASU had notified the project team that these changes would be coming and it was the team’s goal to absorb the modifications made by the new researchers and not let the budget or the schedule be impacted by any changes.
The project team met with the owner and the new principle investigators occupying the space to understand what research requirements and modifications would be necessary in order to make the space fully functional for the incoming team. Design charrettes were held that were accompanied with real-time estimating provided by the McCarthy team, as well as schedule modifications necessary in order to keep the project on schedule and within the budget.
The project finished on time and the building has several specialty researchers conducting very unique, groundbreaking research in the building. The project also remained within the original $120 million budget.
