Even though the COVID-19 virus has tossed the U.S. economy a curveball, don’t expect it to throw the latest addition to Denver’s skyline, a 30-story, speculative office building, for a loop.

The so-called Block 162 is a joint venture of developers Patrinely Group LLC, Denver, and USAA Real Estate, San Antonio. When completed in late 2020, the tower will stand alone among the sources of new downtown Class-A office space for attracting legal, financial and technology-oriented tenants. In fact, Block 162 is one of a just a few speculative office high-rises to come to Denver’s central business district since the 1980s.

Much has changed since then. Both Colorado and the Denver area have grown extensively, the latter undergoing a population increase of 20% in the past decade, up to 720,000, according to the Census Bureau. The influx has translated into stronger market fundamentals and keener competition for tenants.

“Block 162 is seeing a lot of interest from firms looking to relocate to Denver from other parts of the U.S.,” says David Haltom, vice president with Patrinely.

原因之一是,自1980年代以来,租户期望也在发展,而162美元的162块则进行了编程,以领导该包装在强劲的市场中,并在更加困难的后流行条件下表现出色。

随着建筑物接近完成,Patrinely和USAA正在加大努力,以增加与建筑业开始时不太确定市场的租户兴趣。Haltom指出,除其他策略外,开发人员还创建了虚拟巡回演出,包括无人机视频和虚拟租户太空演练。

开发团队正在与其他project team members to employ 3D Matterport scanners, “allowing viewers to step into an actual core-and-shell floor space and see real views within the actual curtain wall line,” he says.

在某种程度上,该建筑的设计对办公室居民的不断变化的习惯做出了反应,后者对灵活,可持续的工作空间溢价了,除了反映了更随意的工作方法的设施外。

与Patrinely Group的经常合作者休斯顿(Houston)的校长和设计总监Raffael Scasserra说,这些设施包括更多的休息室,合作和娱乐场所,或者只是一个休息的空间。


无柱结构

钢制框架办公地板将提供内部无柱的工作区,并宽敞的矩形地板。Haltom称,除了全高玻璃窗户外,这也允许更灵活的计划模块。

总共约有19个办公室,平均为29,500平方英尺,将坐在更大的张紧后的混凝土领奖台上,其42,000平方英尺的地板将容纳一个级别的大厅,并在此级别上占地9级。

夹在办公室和停车场之间,11级从酒店和住宅剧本中借了一到两页,将社交,健身和会议空间混合在一起,这些空间通过40英尺宽的手风琴式的窗墙敞开了户外的天空露台。Scasserra说:“我们希望通过将建筑物开放到户外来利用丹佛气候。”

Haltom说,11,500平方英尺的地板在11楼提供的用途混合物会溢出到讲台结构屋顶上相邻的露台空间上。他说:“我们的健身俱乐部延伸到景观室外草坪上,租户可以自由体重或从事有氧运动和其他体育锻炼。”室内社交空间将设有壁炉和座位区,租户可以独立工作或合作。相应的室外空间将包括其他家具,植物和几个火坑。

“第162号街区看到希望从美国其他地区搬到丹佛的公司引起了很多兴趣。”

Scasserra说,这些空间“反映了两者变得更加灵活的工作和生活方式之间的模糊”。例如,休息室空间“适合快速喝杯咖啡,并在早上散发一封电子邮件,白天或晚上在晚上的鸡尾酒会上进行公司或部门会议,”他补充说。

自2018年以来,该建筑正在建设中,这是一项漫长的研究的结晶,该研究始于2014年,开发商,Gensler和丹佛总承包商Swinerton办公室,是与Pa新利lucktrinely的另一位长期合作者。直到三年后,2017年,Patrinely和USAA为该包裹签署了99年的地面租赁。到那时,团队成员已经充实了他们的大部分计划。

“We assisted in working through design, constructibility and budget issues,” says Chad Holajter, project executive with Swinerton. Client and designer “knew exactly what they wanted,” he adds.

“我们从内而外设计了建筑物,” Haltom说。Office floors dispense with interior columns by locating steel beams beneath concrete and steel deck floors in order to connect the 24 perimeter columns, spaced 30 ft on center, to the core, which is composed of shear walls, says David Chlebus, project director with Houston’s Cardno, the Block 162 structural engineer. Additionally, long-span girders extending between the perimeter and the core’s short end further alleviate the need for interior columns, he says.

Scasserra说,外围柱之间的间距符合5英尺的规划模块,认为是开放式空间或封闭式办公室的理想选择,范围从10英尺到15英尺。

Lease spans from a typical core wall to the inside face of the enclosure measure about 44 ft—longer than the 40-ft to 42-ft spans typical of older office buildings. The larger spans are more efficient for contemporary office tenants and “pay dividends by adding population to a floor while providing greater flexibility in positioning workstations and corridors,” says Scasserra.

霍拉杰特(Holajter)表示,较深的地板不会因全高外部玻璃而损害日光照明,从而从地板到落下的天花板上的尺寸为10英尺。Scasserra说,此外,将玻璃成员“弹跳”光放在内部空间之间的连续垂直金属鳍片。为了避免热量增益,除了在舷外面板内部的低涂层外,还包括0.5英寸厚的窗帘壁单元,尺寸为1英寸。厚度为0.5英寸。


Sustainable Elements

随着建筑物寻求LEED金牌认证,Gensler和Patrinely与ME工程师,MEP设计师丹佛(Denver)密切合作,设计了能量模型,以模拟窗帘墙选项与建筑物的机械系统之间的关系。他说:“合作的努力导致了达到建筑目标的同时满足能源目标的玻璃系统的优化。”

为了适应灵活的地板配置,从封闭式私人办公室到开放式办公室计划,我通过指定专用的外部空气系统(DOAS)增加内部空气通风,其容量比满足典型办公空间的最低ASHRAE 62要求大30%。

“我们将达到27级,每周倾倒大约一层。”

Hays说,它在促进可持续性的策略中,ME通过从建筑物的排气和救济空气系统中转移废热,为DOAS部队配备了能源恢复轮。此外,高效的冷藏水厂配备了水边的节能器,使该厂可以生产冷水以进行冷却过程,同时使冷水机离线。海斯说,水边的节能器非常适合丹佛的干旱气候。此外,该建筑物结合了地板空气处理单元,可促进低静压系统损失,从而获得大量节能。

At present, project team members expect the tower to top out in late June or early July. “We’re up to level 27 and pouring about a floor per week,” says Holajter. However, construction will extend beyond level 30, with crews stacking unitized glazed units to create a crown—or parapet. It rises 32.7 ft above the roofline. In addition to adding sculpture to the building, the parapet obscures the MEP penthouse and other rooftop elements, Scasserra says.

Despite the COVID-19 crisis, construction is proceeding according to schedule. “Swinerton and its subs haven’t missed a beat,” says Haltom.

“We drafted a site-specific plan that, among other initiatives, limits the number of workers who can ride a man hoist to five, each at 6-foot distance from each other,” Holajter says.

斯威纳顿(Swinerton)每天早晨乘员乘坐现场时,都错开了。Holajter说,到达后,所有机组人员都会服用温度并戴上口罩和手套。此外,斯威纳顿(Swinerton)部署了一名专职机组人员来消毒该网站。
