During the next five years you will always find some part of the campus under construction. "We're going to be densifying the core of the campus with more buildings in order to maintain the 10-minute walking circle," explains Rick Keller, campus facilities planning director. But he also points out that many of the projects are going to be on the edges of that core -- such as the Center for the Arts, the stadium and the genome building. This is not to mention the projects really on the "edge" of campus -- the California Dairy Technology Center in Tulare and Lake Tahoe Center for Environmental Research. The most immediate impact will occur this spring for campus commuters who park in lots 1A and 2 near the Buehler Alumni and Visitors Center. Construction on the Center for the Arts could begin as early as May, displacing portions of those parking lots. Since this will likely occur before the new surface lot (south of lots 1 and 2) is completed, the plan is to allow commuters to park on the well- packed aggregate base already in place on the site of the new lot, says Transportation and Parking Services Director Brodie Hamilton. As soon as the rain stops and the site has a chance to dry out, the new lot will be paved. By fall quarter, both the surface lot and the new parking facility next door will be finished with 1,600 spaces available. Old Davis Road will ultimately be rerouted to arrive at the new South Entry Quad and be ready for use when the Center for the Arts opens in fall 2002. For people who work in the campus core, the most noticeable work will result from two major infrastructure projects, according to Scott Arnstzen, a project manager with the Office of Architects and Engineers. Beginning in September throughout the core, bicyclists and pedestrians will be rerouted to avoid 10- to 12-foot deep trenches running along roads and bike paths for an expanded chilled-water program that promises to bring more comfortable summertime air conditioning. You can expect to see heavy equipment and a detour route along Hutchison Drive for six weeks in summer of 2001. The project should take about a year. Our electrical system, which in some places is half a century old, will be replaced and strengthened during a two-year time period. Small trenches will be dug to string new wiring, and 28 transformers across the core campus will be replaced in the older buildings. The old substation will be dismantled next to the Music Building on Hutchison while the substation south of Interstate 80 off Old Davis Road will add another transformer to the existing five. Major trenching work will be conducted from that south Davis site along Old Davis Road north to the junction with the bridge at the University Arboretum Waterway and Putah Creek Lodge Drive. UCDNet 2, the buildout of the Network 21 telecommunications infrastructure system will also occur in the numerous campus research buildings of Old Davis Road south of I-80 such as the Institute of Toxicology and Environmental Health as well as for buildings west of 113. The project will include internal utility closet renovations, placing conduits and pull boxes and digging a few pits for pulling new fiber optic cable and wiring into the buildings. Beginning in 2002, the folks at Transportation and Parking Services are expecting to build Parking Structure 3, Hamilton reports. The site is most likely to be on parking lot 41 across from the Life Sciences Addition, displacing about 250 commuters while the new facility is built. That structure is planned to accommodate between 1,500 and 1,800 spaces by fall 2004. In addition, a new southern leg of Hutchison Drive will be added to connect to La Rue Road when the stadium and aquatics center are built in 2003.
