Iron Bridge LLC, of Spokane, could start work this summer on as much as $22.5 million in new buildings at the Iron Bridge Corporate Campus, located along the Spokane River just east of the University District.


Kent Hull, Iron Bridges managing partner, says the company plans to break ground in June on a $4.5 million parking garage. It hopes to start work shortly thereafter on a four-story, 120,000-square-foot office building there that would cost $15 million to $18 million, though that project is dependent on landing an anchor tenant for the structure.


Hull says he currently is in lease negotiations with a potential tenant that would take the entire structure. He declines for now to identify the prospective tenant, but says he hopes to have the agreement signed later this month.


Construction of the parking structure will move ahead. Hull says the garage will include five levels of parking and 680 parking slots. The structure is expected to take about six months to complete.


That structure will be located along Perry Street, roughly a half-block north of Trent Avenue.


Divcon Inc., of Spokane Valley, will build the big garage.


The envisioned office building would be built on the west side of the office complex, along the Spokane River and just north of the former Sunrise Wood Products Inc. factory, which currently is vacant.


If work on the new office building starts this summer as anticipated, the structure would be completed in time for the potential tenant to move there in the first quarter of 2007.


A contractor for that project hasnt been selected yet.


That structure would be the third building at Iron Bridge. Iron Bridge LLC completed work on the first building there, at the northeast corner of Trent and Perry, in 2003. The second structure, a two-story, 60,000-square-foot building at the northwest corner of that intersection, is being built now and is slated for completion by mid-summer.
