The University of California San Diego (UCSD) needed office space, and they needed it fast.\u00a0 With the new Sulpizio Cardiovascular Center set to open in 2011, the University was in dire need of space for the office, administrative, and clinical research activities supporting that facility and the needs of other Health Sciences programs.<\/p>\n

Considering the budget available for such space and the timeframe they were working with, an initial proposed solution consisting of twelve to fifteen temporary modular buildings was discussed.\u00a0 Bearing in mind the investment that would be required for these units and the reality that the solution would only be temporary, John P. Mattox AIA, LEED AP, Senior Director, Healthcare Project Management for UCSD\u2019s Facilities Design & Construction recommended considering an alternative, tilt-up concrete construction.\u00a0 Mattox, having a great deal of experience with this method as an architect, suggested that a building utilizing tilt-up concrete could be constructed within the difficult budget and timeframe.\u00a0 However, the suggestion was met with reservation from the Design Review Board and other design review agencies on campus.<\/p>\n

UCSD, like most good institutions of higher education, takes their architecture seriously and holds certain design standards to ensure development of the campus is in harmony with the existing architectural icons anchoring it.\u00a0 \u201cThe Design Review Board expressed serious doubts as to whether a tilt-up building would measure up to the high standards of design that the university has come to expect,\u201d said Mattox.\u00a0 Nevertheless, a request for proposals (RFP) for the East Campus Office Building was released.<\/p>\n

The winning design-build proposal was submitted by C.W. Driver, a top-100 nationally ranked general contractor, and Gensler, a global architecture, design, planning and consulting firm with 3,500+ professionals in more than 40 locations.\u00a0 Tom Heffernan, AIA, LEED AP, the Principal in charge of the project for Gensler noted that the request for proposals issued by the University suggested tilt-up concrete construction as a good means of addressing the project requirements with its budget limitations and aggressive schedule.\u00a0 \u201cThe team took this to heart and focused efforts on developing a tilt-up design that expressed the sculptural potential of site cast concrete,\u201d said Heffernan.\u00a0 \u201cUCSD and its surrounding community have a rich history of traditional cast-in-place concrete and we welcomed the challenge to use tilt-up methodology in an innovative way to design a new building that could hold its own among the other buildings on campus.\u201d<\/p>\n

According to Mattox, the proposal was well received and aided in the buy-in of the Design Review Board, which was elemental to the project\u2019s realization. Mattox was especially impressed with the team\u2019s approach to the tilt-up method, which proudly showcased its potential.\u00a0 \u201cMany tilt-up buildings in our region try to hide behind paint or applied veneer,\u201d noted Heffernan.\u00a0 \u201cWe were determined to design a tilt-up structure that used the material integrally as the primary architectural expression of the project.\u201d<\/p>\n

Beyond architectural integrity, Gensler noted that the decision to utilize tilt-up concrete construction ultimately came down to the fact that they were able to provide a higher level of value to the University. Given a very detailed RFP, a fixed budget, and straightforward campus requirements, C.W. Driver was able to estimate the costs of the interiors as well as the mechanical, electrical and plumbing (MEP) systems with a high level of accuracy.\u00a0 What remained were the funds available for the skin, or fa\u00e7ade, and structure.\u00a0 \u201cWithin this budget we could provide a conventional steel framed building, but would only have enough budget left for a stucco or other low cost cladding system,\u201d explained Heffernan.\u00a0 \u201cWith the \u2018triple duty\u2019 tilt-up system \u2013 cladding, lateral, and gravity system in one \u2013 we could provide a much higher level of quality to the University.\u00a0 A durable system with low maintenance requirements and, equally important, a system that afforded us powerful design opportunities.\u201d<\/p>\n

Jeff Crosier, S.E., Principal with Miyamoto International, a global earthquake and structural engineering firm, served as the project\u2019s structural engineer:\u00a0 \u201cOnce we determined we could achieve the design elements of the panels with an economical structural design as well, there were absolutely no reservations with regards to the delivery method.\u201d\u00a0 Miyamoto International has completed hundreds of tilt-up projects across the globe. According to Crosier, \u201cTilt-up can be a very cost and schedule effective means of construction that, with a higher level of engineering capability and architectural creativity, can achieve a building with unique design features and high quality.\u201d<\/p>\n

The utilization of tilt-up as the delivery method for the project enabled the critical timeline for the project to stand. Andy Feth, P.E., Project Executive for C.W. Driver, estimated the use of tilt-up provided a four-week schedule advantage over alternative framing\/cladding systems. \u201cNow more than ever it is important for campus projects to be delivered on time, on budget, and with limited disruptions to the surrounding operational facilities,\u201d said Garrett Wilson, Project Manager for C.W. Driver. \u201cBy addressing this challenge early on and frequently communicating with UCSD, our design-build team worked closely together to take the design to the fullest extent within a specified budget, which allowed for our team to achieve a wonderful facility for UCSD that will be celebrated for years to come.\u201d<\/p>\n

Knowing the project would be under some scrutiny, Mattox was impressed with the design team\u2019s attention to every detail, specifically, their awareness and acknowledgment of the building\u2019s context.<\/p>\n

 <\/p>\n

The project mediates between the natural, rustic character of the campus edges, and the highly designed character within the central core.\u00a0 The combination of concrete and glass comments on this relationship and helps to ground the building in its context.\u00a0 The relatively rough concrete walls address the canyon side of the site, referencing that geology, while the clean and sophisticated glass fa\u00e7ade reflects the formality of the campus landscape.<\/p>\n

The positioning of the concrete walls which sit forward of the curtain wall further refines the relationship between the two materials.\u00a0 \u201cAlthough the vertical joint between the concrete and curtain wall is not dithered, the perceived overlap in plane is intended to suggest that the building is a glass box protected by a concrete wrapper that sits outside of it,\u201d Heffernan described.\u00a0 \u201cThis effect is further emphasized by the stair tower that appears to bulge out from the concrete, and by the southwest corner that is inset and empathized by vertical reveals.\u201d<\/p>\n

In multiple locations, the panels elegantly extend beyond the face of the building.\u00a0 \u201cWe wanted to express the construction methodology clearly and create a legible expression of the different panel thickness,\u201d explained Heffernan.\u00a0 \u201cWe used building information modeling (BIM) and other methods of three-dimensional representation extensively to look at different iterations of these corner conditions and settled on configurations that created interesting profiles against the sky.\u201d<\/p>\n

 <\/p>\n

The project is surprisingly light and airy considering the majority of the exterior is composed of concrete walls with punched openings.\u00a0 The verticality of the openings accentuated by the projecting vertical sunshades, coupled with the tall slender composition of texture and relief, break down the scale and weight of the sizeable elevations.\u00a0 The shifting of the motif vertically denies a strong horizontal reading, which is often dominant in traditional office buildings.\u00a0 This strategy extends to the top of the structure where the horizontal line of the parapet is broken.\u00a0 The syncopated rhythm of the punched openings and metal sunshades further denies a static reading, encouraging movement along the face of the building, taking the eye up and down as it moves along.<\/p>\n

Just as the fa\u00e7ade shifts vertically in elevation, the various levels of relief provide complimentary movement in plan, breaking the flat plane of the wall. While the concrete is not painted, the perceived value and even hue of the material changes as deeper textures create shade and shadow and varying levels of sandblasting expose different aggregates.<\/p>\n

The unitized glass curtain wall system mimics the pattern and texture of the concrete. Fritting on the curtain wall panels at the southwest corner of the building mirrors the striated texture created by the formliners in the concrete panels.\u00a0 Again, the various treatments produce changes in the appearance of the glass.<\/p>\n

\"\"<\/a>

The process of selecting and testing the finish for the panels was aided tremendously by the early involvement of both the formliner manufacturer and the tilt-up subcontractor, Minegar Contracting, Inc.\u00a0 Presented with an architectural rendering conveying the desired composition and texture, Mike Dahlquist, President of Minegar, worked closely with the team to realize the design intent. Miyamoto International oversaw decisions of panel thickness and joint locations to ensure panel weights were manageable for the crane scheduled to do the lifting.<\/p>\n

As construction began, Minegar built an off-site mock-up panel showcasing multiple formliner variations and various levels of exposed aggregate finishes.\u00a0 \u201cThis experiment allowed us to balance design with budget before committing to an on-site mock-up where we fine tuned the finishes,\u201d explained Heffernan.<\/p>\n

The structural thickness of the panels is ten inches, although the thickness varies from twelve to six inches thick at certain non-structural locations within the panels.\u00a0 This varying thickness coupled with the offset window openings required additional engineering.\u00a0 \u201cA more sophisticated finite element structural analysis was performed on the spandrel elements of the panels to optimize structural performance,\u201d explained Crosier. Each panel was divided into three-foot sections.\u00a0 Each of those sections incorporated two distinct textures and two different levels of relief.\u00a0 The recessed areas of the panel were formed at varying depths with masonite decking.<\/p>\n

Because there was not enough space on the building slab to cast the panels, a fairly common situation on projects with a relatively small footprint compared to wall area, recyclable casting slabs were planned at convenient locations.\u00a0 A well-organized panel layout and carefully thought-out sequencing allowed all panels to be set efficiently even though crane access was not possible on all sides of the project.<\/p>\n

The structural system for the project\u2019s floors and roof consists of metal deck with lightweight concrete fill, supported by long-span steel joists.\u00a0 The walls are tied into both the floor and roof systems via dowels embedded in the concrete.\u00a0 \u201cThe panels are connected to the continuous footing foundations through the use of dowels into pour strips and then to the continuous footings with hold-down anchors installed at panel ends where seismic forces create uplift,\u201d said Croiser.<\/p>\n

\"\"<\/a>

The building exceeds the California Code required energy savings by 16% and is seeking LEED\u00ae Silver certification.\u00a0 \u201cThe availability of local products contributed significantly to the sustainability of the project,\u201d explained Crosier.\u00a0 \u201cWith the entire building shell procured locally, transportation of construction materials over the road from non-local sources was significantly reduced.\u201d<\/p>\n

Programmatically, the project is fairly complex.\u00a0 The 75,000-square-foot building features office and meeting spaces on all three levels.\u00a0 The main floor also includes exam rooms and a caf\u00e9.\u00a0 The new medical office space will hold a first floor Clinical and Translational Research Institute consisting of exam rooms, a pharmacy, treatment rooms, blood draw rooms and related support areas including waiting rooms, restrooms, and a reception area.<\/p>\n

Tilt-up was a great fit for the project, considering the large number of private offices requiring a window.\u00a0 \u201cBecause these offices all needed to be the same size, and there were so many that they filled almost the entire perimeter of the building, we could provide one punched window per office,\u201d said Heffernan.\u00a0 \u201cThis kept the glass to wall ratio much lower than if the building was all curtain wall like a conventional speculative office building and reduces the cooling load.\u201d Beyond the environmental responsibilities of the structure itself, the new facility will improve efficiency and enhance collaboration by consolidating related research and associated staff that were previously scattered among several locations in one building.<\/p>\n

The $25 million facility is the very first academic building on UCSD\u2019s campus to employ tilt-up concrete construction. The design excellence achieved is just one more example of the potential of tilt-up concrete construction. \u201cThe project is very well done,\u201d but not to Mattox\u2019s surprise; \u201cI knew we had the right team on the job!\u201d The majority of concern and criticism related to the building\u2019s construction method has subsided and, for many, it is now considered to be a very attractive addition to a campus that has prided itself in excellent design and a beautifully built environment.<\/p>\n
