Construction Standards and Costs

UC Irvine new construction pursues performance goals and applies quality standards that affect the costs of capital projects. Periodic re-examination of these goals and standards is warranted. Construction costs are not “high” or “low” in the abstract, but rather in relation to specific quality standards and the design solutions, means, and methods used to attain these standards. Thus, evaluating whether construction costs are appropriate involves:

bull;first, determining whether quality standards are excessive, insufficient or appropriate;

bull;second, determining whether resultant project costs are reasonable compared to projects with essentially the same quality parameters. “Quality” encompasses the durability of building systems and finishes; the robustness and life-cycle performance of building systems; the aesthetics of materials, their composition, and their detailing; and the resource-sustainability and efficiency of the building as an overall system.

overall Goals and Quality Standards

UC Irvine, in order to support distinguished research and academic programs, builds facilities of high quality. As such, UC Irvinersquo;s facilities aim to convey the “look and feel,” as well as embody the inherent construction quality, of the best facilities of other UC campuses, leading public universities, and other research institutions with whom we compete for faculty, students, sponsored research, and general reputation.

Since 1992, new buildings have been designed to achieve these five broad goals:

1. New buildings must “create a place,” rather than constitute stand-alone structures, forming social, aesthetic, contextually-sensitive relationships with neighboring buildings and the larger campus.
2. New buildings reinforce a consistent design framework of classical contextual architecture, applied in ways that convey a feeling of permanence and quality and interpreted in ways that meet the contemporary and changing needs of a modern research university.
3. New buildings employ materials, systems, and design features that will avoid the expense of major maintenance (defined as gt;1 percent of value)for twenty years.
4. New buildings apply “sustainability” principles -- notably, outperforming Title 24 (Californiarsquo;s energy code) by at least 20 percent.
5. Capital construction projects are designed and delivered within the approved project budget, scope, and schedule.

UC Irvinersquo;s goals for sustainable materials and energy performance were adopted partly for environmental reasons, and partly to reverse substantial operating budget deficits.

The latter problems included a multi-million dollar utilities deficit that was growing rapidly in the early lsquo;90s, and millions of dollars of unfunded major maintenance that was emerging prematurely in buildings only 10-20 years old. Without the quality and performance standards adopted in 1992, utilities deficits and unfunded major maintenance costs would have exceeded $20 million during the past decade, and these costs would still be rising out-of-control.

UC Irvinersquo;s materials standards, building systems standards,sustainability and energy efficiency criteria, and site improvements all add cost increments that can only be afforded through aggressive cost management. Institutions that cannot manage capital costs tend to build projects that consume excessive energy, that cost a lot to maintain, that suffer premature major maintenance costs, and that require high costs to modify. Such problems tend to compound and spiral downward into increasingly costly consequences. Every administrator with facilities experience understands this dynamic. Without effective construction cost management, quality would suffer and UC Irvine would experience all of these problems. The balance of this document outlines in greater detail the building performance criteria and quality standards generally stated above, organized according to building systems component classes. Each section discusses key cost-drivers, cost-control strategies, and important cost trade-offs. Design practices cited are consistently applied (although some fall short of hard and fast “rules”).

Building Organization and Massing

Construction cost management starts with the fundamentals of building organization and massing. UC Irvinersquo;s new structuresrsquo; floor plates tend to have length-to-width ratios lt;1.5, to avoid triggering disproportionate costs of external cladding, circulation, and horizontal mechanical distribution. Our new buildings tend to be at least three floors high -- taller if floor plate areas do not dip below a cost-effective threshold, and generally taller in the case of non-laboratory buildings (but not so tall that a high-rise cost penalty is incurred). Other design ratios are observed, such as exterior cladding area/floor area lt;0.5, and roof foundation area/floor area lt;0.4.

Architectural articulation is generally achieved through textured or enriched materials,integral material detailing (such as concrete revealpatterning), and applied detailing (e.g.,2window frames and sills), particularly at the building base. Large-scale articulation is concentrated at the roofline (e.g., shaped roof forms) and at the pedestrian level (e.g.,arcades), where it will “create the biggest bang for the buck,” rather than through modulating the building form, itself. This is more than a subtle design philosophy, as the cost impact is substantial.

Lab buildings completed in the past decade separate laboratory and non-laboratory functions into distinct, adjoined structures (although such a building may look like one structure). Consolidated non-laboratory functions include faculty, departmental, staff,post-doc, and graduate student offices; restrooms; circulation (elevators, lobbies, primary stairways); classrooms, semi
