明尼苏达州亨内平县明尼阿波利斯-圣保罗国际机场4.8亿美元能源改造：1号航站楼锅炉与制冷厂将重建
明尼苏达州亨内平县布卢明顿市的明尼阿波利斯-圣保罗国际机场将启动一座耗资4.8亿美元的能源改造工程。10月28日公布的消息说，承包商杰伊·邓恩建筑公司已被选为1号航站楼锅炉与制冷机更换及能源管理中心扩建项目的风险施工管理方，大都会机场委员会已于9月22日批准这一选择。
工程将改造为1号航站楼及其停车结构供暖制冷的中央公用设施厂，该厂自上世纪60年代初随航站楼投用、目前全天候运转，已到使用寿命终点，服务面积超过300万平方英尺，约占机场天然气用量的75%。
按计划，现有能源管理中心建筑将被拆除重建，蒸汽锅炉厂升级、冷冻水厂全部更换，并新建工业热回收制冷系统和热水分配系统，还可能建设28口井的地热系统。
工程还包括C候机厅6个登机口区域的重建扩建，约18.34万平方英尺旧空间将被拆除、新建约31万平方英尺设施，洗手间、餐饮、航空公司用房和机场支持区也将改善。规划设计正在进行，前期工程预计2027年启动、主体施工2028年开始、2032年完工，施工期间机场保持全面运营。
$480 Million Energy Overhaul at Minneapolis-St. Paul International Airport: Terminal 1 Boiler and Chiller Plants to Be Rebuilt
Minneapolis-St. Paul International Airport in Bloomington, Hennepin County, Minnesota, is set to begin a $480 million energy overhaul. According to an announcement on October 28, contractor JE Dunn Construction has been selected as construction manager at risk for the Terminal 1 boiler and chiller replacement and Energy Management Center expansion project; the Metropolitan Airports Commission approved the selection on September 22.
The project will overhaul the central utility plant that heats and cools Terminal 1 and its parking structures. The plant has operated around the clock since the terminal opened in the early 1960s and has reached the end of its useful life; it serves more than 3 million square feet and accounts for about 75 percent of the airport's natural gas use.
Under the plan, the existing Energy Management Center building will be demolished and rebuilt, the steam boiler plant upgraded, the chilled water plant fully replaced, and new industrial heat-recovery chiller and hot water distribution systems built, possibly along with a 28-well geothermal system.
The project also includes rebuilding and expanding six gate areas in Concourse C, demolishing about 183,400 square feet of old space and building about 310,000 square feet of new facilities, with improvements to restrooms, concessions, airline space and airport support areas. Design work is under way; early work is expected to start in 2027, main construction in 2028 and completion in 2032, with the airport remaining fully operational during construction.
