今年夏天，犹他州历史上最复杂的建筑项目之一达到了中途。新利18备用网址自2014年以来，盐湖城机场航站楼的36亿美元替补位于距市中心近5英里的位置，在与当前工厂相邻的地点上一直在稳步上升。
During the effort, hundreds of workers have performed ground-stabilizing work, placed concrete and erected steel, all while the scope of the project expanded to include an entirely new concourse.
“这有点像在您所居住的房子上建造一栋新房子，”总部位于亚特兰大的制作项目的计划总监兼总裁Mike Williams说。新利18备用网址他的公司被盐湖城保留，以指导码头替换计划，并担任所有者代表。“目前，我们计划在2020年秋季开放该项目的第一阶段，然后我们将开始拆除现有机场的各个部分，以便我们可以建立下一阶段并在2024年之前完成总替换。”
新航站楼占地296.7英亩，直接在现有航站楼的南部和西部，将有74至78个大门，一个3,600台的五级停车场，还有另外1200个租车摊位，用于租车，轻轨连接，一条高架路线为了离开乘客和908,754平方英尺的主码头，其Concourses向东和西部延伸。主要航站楼北部的第二个新的大厅将由隧道连接。
Commissioning will soon begin on a 25,000-sq-ft, two-level central utility plant to come online this fall. A new park-and-wait lot with concession facilities and a gas station opened last fall.
Long Time Coming
The current Salt Lake City Airport is a collection of buildings, some of which date back to 1960. Last year more than 24 million passengers passed through the airport, at least twice what it was designed to serve, according to SLC Airport representative Nancy Volmer. It is the 25th busiest in North America and has served as a regional hub for Delta Airlines since the late 1980s.
需要一个新的irport has been clear to the facility’s directors since the mid-1990s, according to Kevin Robins, director of engineering for the airport. In addition to logistical limitations, the seismic readiness of the facility, which was built on an ancient lake bed and near an active earthquake region, was a chief concern. Changes in airport design following 9/11, the impact of Salt Lake City’s hosting the 2002 Winter Olympic games and the bankruptcy and reorganization of Delta Airlines all contributed to pushing the project back.
2007年，总部位于旧金山的建筑和工程公司HOK订婚开始概念研究和初步编程。
A joint venture of Salt Lake City-based Big-D Construction and Holder Construction of Atlanta was selected for the construction manager at-risk contract in fall 2013.
该项目分为两个阶段。第一阶段将于2020年完成，包括新的停车场和通道道路，以及一个带有国际航班大门的主要航站楼。在第二阶段，将于2024年完成，机组人员将拆除国际航站楼和两个Concourses，从新航站楼为东大厅的翅膀腾出空间。随着新的东方大厅完成，Concourses将覆盖3,691英尺。
Steady for Take Off
2014年的初步工作着重于重新安排通行道路和公用事业，并准备该站点，以便在新的停车场开始建设。早期挑战是稳定土壤以稳定土壤的现场工作。
“地下水位在这里只有4至7英尺，”机场码头重建计划副主任Tad Kaczor说。该地点用近7,612个石柱稳定下来，以支撑板层并防止沉降。根据总部位于盐湖城的Dunn Associates Inc.的泰勒·赖特（Tyler Wright）的说法，结构支撑在5,489个驱动的桩（其中有近7英里）的深处，有些深70英尺。终端和concours。
Wright says the seismic requirements from HOK were set at risk category 3 and 4, meaning it could be immediately occupied following a seismic event.
“The facility wouldn’t be functioning, but you could safely get people in to make repairs,” says Wright. “The seismic system for the concourses is BRBs (buckling-restrained braces) in the east and west direction and then the north and south system is done with side-plate moment frames with 36-in. columns. It’s the same for the TSA [Transportation Security Administration] portion of the terminal. Then we have BRBs in both directions for the terminal.”
Additionally, Wright says there are seismic separations about every 300 to 400 ft along the concourses as well as in the terminal.
一个新的大厅
The most significant change to plans has been the addition of a second concourse parallel to, but north of, the main terminal and concourses. A north concourse had been envisioned in earlier plans but was not part of the scope of the original terminal replacement.
Two older hub-type concourses were initially going to be retained. Robins says that new information from the airlines about passenger volumes and the size of future aircraft drove the decision to add the new concourse now.
“About three years ago, we took another look at the numbers of gates and what the airlines were telling us they would need,” says Robins. “The demand was more than we would have expected. In Phase 2 of this project, we were going to seismically upgrade and rehabilitate those old concourses, which would mean closing them, and that would leave us with even fewer gates while that was being done. We were going to spend money to rehabilitate those concourses, and we just decided the funds would be better spent if we went ahead and just built new,” he says.
The announcement to build the north concourse was made in spring 2016, and a joint venture team of Okland Construction, Salt Lake City, and Dallas-based Austin Commercial, known as Austin-Okland Aviation, was awarded the CMAR contract.
A nearly 1,000-ft-long tunnel constructed during earlier airside work in the mid-2000s will connect the west concourse of the new terminal to the north concourse. Kaczor says a larger central tunnel, with shelled-in space for a future passenger tram from the center of the main terminal building, will be built to connect with the north concourse, which will open in 2024.
Kaczor said making the connections at either end of the existing tunnel has been a challenge because it required an extensive shoring and temporary dewatering system.
Making It Utah Unique
In response to early conceptual work and surveys by the architects, the new airport will have touches that make it unique to its location, both inside and out.
犹他州是主要的铜生产商，HOK设计师为大部分结构指定了铜覆层。
A two-story corridor space lined with shops and restaurants will be known as The Canyon and will feature an articulated, wave-like pattern referencing the multi-layered rock prevalent in Utah’s canyons. The canyon will be lit by multicolored LEDs featuring tones common in the state. The feature is being crafted from aluminum tubing and composite fabric by California artist Gordon Huether.
峡谷将通向一个中央广场区，上面有三层楼的玻璃窗，并欣赏周围山脉和飞机场的景色。东方和西方的Concourses将连接到广场，自动扶梯将连接到通往北部大厅的中央隧道。
Another feature of the new airport will be the meet-and-greet area. Since Salt Lake City is the headquarters of the Church of Jesus Christ of Latter-day Saints, the airport often hosts large crowds greeting family members departing or returning from church missions.
“This area will be almost like a living room and will give some space for those groups away from the baggage claim or arrival gates,” says Kaczor.
The six miles of baggage belts also have unique features, he says. Large items such as skis, golf clubs and even bicycles can be conveyed from any check-in desk in the facility and can likewise be claimed in one central area.
The project is being financed through airport bonds that will be repaid through a combination of ticket fees and gate, concession and car-rental fees.
