匹兹堡国际机场计划的650,000平方英尺的新航站楼的设计团队在3月几乎达到了60％的设计标记，所有者正准备发布预备合同。

然后是Covid-19。

乘客和收入暴跌,机场的ficials pressed pause on the design and set up four workshops over the next several weeks, recruiting public health experts from the local community of research and university entities, says airport spokeswoman Alyson Walls. “We decided to take the opportunity to really look at our design and everything that was happening in terms of new health standards, new realities of air travel and what that may look like in the future.”

Gensler，HDR和Luis Vidal + Architects的设计团队利用HDR的医疗保健团队为大流行终端的塑造提供了信息。“We’re looking at how to take our biocontainment expertise in hospitals and research laboratories, including lessons learned, and apply it to potentially help the environment within an airport to minimize the transmission of disease pathogens,” says Chris Bormann, HDR’s East region health director.

两个研讨会发生在四月和五月。沃尔斯说：“提出外卖还为时过早，但目的是确定优先事项。”“我们可以做些什么来进行更改？每个人都在寻找持有房间，门区域布局，安全检查站，票务柜台 - 人们聚集的地方。我们可以在地板和口罩上看到什么？对于未来来说，这可能还不够。”

Participants are assessing technologies that better control the flow of passengers through a terminal, such as a digital queue that would involve assigned times to go through security, biometrics, thermal scanning and potential separation of incoming passengers from outbound passengers at the gates. Elements such as UV lights, natural light, oxygen flow and cross ventilation, and touchless technologies are all in play, says Luis Vidal, the architect on the team.

HDR Aviation总监Bill Peduzzi说，匹兹堡机场有机会设计最早的大流行终端之一的情况并不常见。“我们的大多数客户要么处于具有维护设施的静态位置，要么目前更改它的能力有限。”

全国各地的机场官员正在加快目前的建设，思考一些计划中的项目的命运，并在短期，长期和长期检查中检查含义。新利18备用网址

Ryan Fetters, principal with Gensler, says several airports across the globe, including San Francisco International Airport, have participated in workshops to address these implications.

他说：“ SFO的印象是，这就像9/11之后的第二天，现在已经进行了两个多月。”“这是该行业的范式转变。目前，由于没有多少人在建筑物中，社交距离很简单，但是当人们再次开始飞行时，中期会发生什么？”

He adds: “Now is the time to double down on empathy and how we work with our partners and clients to deliver these projects.”

乘客交通急剧下降使大都会华盛顿机场管理局能够加速在里根国家机场的65870万美元项目旅程领导的几个建筑项目的工作，该项目定于2021年完成。新利18备用网址，225,000平方英尺的大厅和两座新的50,000平方英尺的安全检查站建筑物。玻璃和金属面板悬挂在外部时，公用事业的工作正在进行中。

MWAA工程高级副总裁Roger Natsuhara表示，最近几个月的建设步伐更快，一夜之间的工作转变为日光。Natsuhara补充说：“随着我们意识到其他部门的供应链问题，我们对物质订单保持了密切关注，以确保交付持续而不会大幅中断。”

减少的飞机活动使MWAA能够加快在杜勒斯国际机场的新消防栓加油坑，以及两个机场的跑道和出租车维修。

Looking ahead, Natsuhara says that MWAA is examining its full slate of approved projects to prioritize those that should go forward and identify others for deferral in order to preserve capital.

Natsuhara说：“由于设施的可用性，维修和新利18备用网址维护项目可能会前进，而改进和扩展项目可能会延迟，因为对该项目的需求延迟。”“我们与包括财务团队在内的多个利益相关者紧密合作，以确定何时应进行项目。”

Similar examples abound at airports with major modernization programs, such as Salt Lake City International Airport. Its $4.1-billion program will now finish two years early with an estimated cost savings of $300 million.

但是，对合同和未来建设有什么影响？“在4月的大部分时间里，我们大多数成员的重点是审查金融可持续发展轨迹所必需的，”机场委员会国际北美委员会安全和监管事务高级副总裁克里斯·奥斯瓦尔德（Chris Oswald）说。他说：“在接下来的六到18个月中，您所有的运营和维护收入来源都已被掩盖。”他说，这影响了机场在资本计划的新债务负担方面所能承受的。

Aci-NA与美国相关的美国总承包商和机场顾问委员会，正在主持一系列网络研讨会代替其年度建筑峰会，研究了现在及以后对建筑合同的影响。

“显然，我们都在努力保持项目的进行，” Americas地区HKA的合伙人兼总裁Frank Giu新利18备用网址nta说，他主持了第一个网络研讨会。“我们还讨论了问题 - 这是不可抗力的吗？合同怎么说？保证的最高价格是否由于千载难逢的条件而无效？”

消息人士认为，考虑到病毒期间的不确定性，完全解决长期解决的时间为时过早。Giunta说：“现在的重点是沟通和协调，然后是合同问题。”

While most contracts allow some relief for construction delays caused by certain enumerated or extraordinary events, the clauses may differ about whether contractors are compensated monetarily, notes Jim Newland, partner at Seyfarth Shaw LLP and another webinar moderator. On public projects, some states preclude the use of “no damages for delay” clauses that prevent contractors from recouping associated costs. But when they are enforceable, “generally speaking, owners may owe the contractor an extension of time, but no money,” Newland adds.

需要更好的沟通,同时社会说tancing aligns with the airport world’s trend toward design-build and construction manager-general contractor delivery approaches, says Oswald. “A major takeaway is the need and reality of cooperation among parties.”
