一个世纪的形成

航拍钟楼

这个故事是一个正在进行的系列的一部分修复及完成纪念钟楼.点击链接,了解更多关于北卡罗来纳州的石头传奇的历史。

近一个世纪以来,纪念Belltower一直是北卡罗来纳州立大学最神圣、最受认可、最上镜的地方。

但钟楼的形象即将改变。几个月后,脚手架将出现在塔的外立面周围,一项650万美元的完工和修复项目正在认真进行中。

官员们计划在今年秋天开始对外可见的第一阶段工作。该工地的建设将持续一年多一点。今年夏天结束的是为期一年的设计阶段,包括广泛的研究、测试和规划。

钟楼要建多久?

修复和完工将于2019年秋季开始——围栏将于8月26日开始修建——并将持续一年多一点。该项目包括修复大面积的水损坏和恢复塔的外部和内部;改善可达性,并将场地开云体育官方登录翻新为亨利广场;升级照明和电力等系统。最重要的是安装了一个55个钟的钟楼,包括一个位于钟楼下方的玩耍小屋,这需要在塔内增加楼梯才能到达那个房间,以及一个新的暖通空调系统。工作将分阶段进行。

真正的钟声何时才会第一次响起?

2020年底或2021年初。请继续关注!2010届毕业生买的铃铛怎么了?2010届毕业生的钟,以及在“完成钟楼”活动中购买的另外四座钟,都被封存起来。(一些展品在D.H. Hill Jr.图书馆展出,直到包括重新开放希尔斯堡街入口在内的改造项目开始。)它们正在进行调整,以便与其他新钟协调工作,并安装在塔上。

这个项目将对那些希望在今年12月或2020年春天拍摄毕业照的人产生什么影响?

项目团队的目标是尽可能为戒指仪式和其他与毕业相关的活动提供一些入口,比如照片(记住,该地区是一个现场施工现场,安全是最重要的)。天气等因素可能会改变这种可能性。

我们还能把塔点亮吗?还有什么受到影响?

八月的一场雷雨吹倒了基座上四个主灯台中的一个;出于安全原因,所有这些都被暂时移除。(他们的恶化是该项目的必要性的另一个例证。Packapalooza使用了一个非常临时的解决方案。)所以简短的回答是,暂时不会。但好消息是:改进将包括增加白色照明,可以展示钟声,以及升级的红色照明。同样,在部分施工过程中必须断电,这意味着时钟(计划对老化的系统进行数字升级)和扬声器将无法使用。这些变化值得等待。

最值得注意的是,经过近一个世纪,钟楼的55个钟正在路上。在施工期间,它们将安装在顶部的开放式钟楼上,目前钟楼只有一个扬声器系统。

达米安·拉拉辛(Damian Lallathin)是该大学资本项目管理部门的工程师,他作为项目经理与大学建筑师办公室密切合作,负责钟楼的修复和完工工作。他说:“能完成这么久以前就开始的项目,将永远屹立在这里,我感到很荣幸。”

钟声是令人兴奋的头条新闻。但该项目也将解决几十年来对塔内外、地基和周围环境的水破坏。施工的早期阶段将通过清洁、维修和现场改善来重点关注这方面。

工作清单上还包括:改善包括轮椅使用者在内的游客到达基座(塔所处的凸起开云体育官方登录平台)的可达性;以钟楼为例,底座的高度比周围的大厅或广场高出3.5英尺多一点。虽然钟楼的占地面积不会真正改变,但项目团队将重新配置离普兰路停车位最近的一侧。旗杆的位置将改变,一条新的宽的、逐渐上升的道路将从停车场通往基座,取代广场基座南侧的台阶。通过台阶和停车场附近的坡道可以到达上行路径。

各种系统升级也将进行,从新的LED照明到用同步数字装置取代旧的机械发条。

工作完成后,该区域将被专用为亨利广场的纪念钟楼,以纪念对该项目的慷慨的主要捐助者。加斯顿尼亚的比尔(81)和弗朗西斯·亨利(Frances Henry)于2017年秋天捐赠了这笔礼物,作为该大学16亿美元转型资金的一部分思考和行动的非凡战役.多年来,还有许多人为这座塔做出了贡献。

漫长的完成之路

慈善、合作和对北卡罗莱纳州及其人民的爱一直是这座115英尺高的钟楼故事的核心,该钟楼在20世纪20年代至40年代期间被分拆建造。

万斯•赛克斯1907年北卡罗莱纳州的类成员,领导一个校友委员会,聘请纽约建筑师威廉·亨利·Deacy 1920年设计的,以纪念牺牲的校友服务死于第一次世界大战在1921年奠定了基石,但是大萧条和第二次世界大战和一个相应的资金缺乏意味着Belltower建于时断时续,尽管校友和其他领导人的努力包括卡洛尔曼教授。

这座石雕作品是在1937年由联邦工程发展局完成的。1938届学生和学生荣誉协会捐赠了这座钟,1939届学生购买了泛光灯。在完成了其他收尾工作后,包括完成了神社内部的房间和它的纪念牌,正式的奉献仪式于1949年11月11日举行。

然而,最初的钟声愿景从未实现,所以从技术上讲,钟楼只是一个名义上的钟楼。多年来,随着其他校园设施的需求优先获得资金,该结构主要进行了关键的修补。

但近年来,在亨利夫妇的支持使该项目完全成为可能之前,捐助者对完成钟楼重新产生了兴趣。

五个钟例如,他们是通过马修·罗宾斯(Matthew Robbins)和其他当时的学生发起的草根运动“完成钟楼”(Finish the Belltower)购买的。这些大钟——包括北卡罗来纳州立大学2010届毕业生购买的、将成为大本钟最大的2000磅大钟——都被储存起来,等待调试后安装。另外还为另外三个钟筹集了资金。

“这是为了纠正历史,”罗宾斯谈到“完成钟楼”的努力时说。他和校友迈克尔·汤普森(Michael Thompson)完成了对塔和它所纪念的人的大量档案研究。“我们想继承建造钟楼的人们留下的遗产,在无人倾听的地方倾听。当你阅读建筑师和委员会之间的信件时,你几乎可以听到没有足够的钱来完成这座纪念碑的核心的痛苦。就好像他们直接在跟我们说话。”

弗吉尼亚州里士满北部的桑德林钟铸造厂将从今年夏天开始铸造剩下的55个钟。

是的,工人们最终会拆除钟楼的顶部,并使用起重机将每个钟放入一个巨大的框架中。

Crews will use a crane to temporarily remove the roofing and roof structure and to lower the largest bells into the belfry. Roof removal also allows installation of the bell frame. Copper roof flashing and portions of roofing are being replaced, and the roof structure will be reinforced with additional steel. The adjacent portion of the upper structure of the belfry, damaged by a 2009 lightning strike, will not be repaired.

At long last, a bell frame and 55-bell carillon will be installed in the belfry, the open area at the tower’s apex, replacing the old speaker system. Bells have been purchased both with the Henry gift and through the generosity of donors to an earlier campaign a decade ago. Many of the largest bells will arrive at the tower already attached to headstocks, or horizontal steel beams; all of the bells will be assembled into a large stainless steel frame with cables and cranks tying into the playing cabin below. Work on the belfry includes the erection of additional structural steel beams and a reworked slab providing the right configuration for the carillon design and added support for the bell system. There’s also cleaning, painting, waterproofing and curbing. Copper mesh screening will be installed behind the granite columns to keep out birds, bats and nesting insects, and the belfry will have white lighting.

The tower’s existing, rusty clockworks will be removed and replaced by a digital system with mechanical connections.

The slab forming the base of the clock level, nearly 77 feet above the Shrine Room floor, is being removed to make space for the new playing cabin below.

A wood-paneled and concrete-floored room is being built just below clock level. This carillon room, or clavier playing cabin, will feature a new wooden keyboard instrument — a red oak console complete with keys, batons and foot pedals. Two of the instrument’s four posts will be shaped like the Belltower itself. With the demolition of the existing clock-level slab to open the area below it, the upper part of the playing cabin will feature skylights into the belfry floor. These can be opened when a musician is playing, so he or she can clearly hear the bells. An auxiliary control panel in Holladay Hall will enable electronic operation of the carillon.

The tower’s “windows” have simply been openings with screens— one of several features leading to interior condensation and water damage. A new interior, fixed-sash window shutter system will keep out rain. The windows will be fixed rather than operable to decrease potential maintenance (including the possibility of one being left open inadvertently).

A set of decorative winder stairs is being installed, similar to the original design. The lowest portion of the stairs in the Shrine Room will be styled in a more decorative fashion, featuring treads made of marble and serpentine, a lustrous green mineral; design details from architect Deacy’s drawings; and iron and bronze railings. As you ascend from the new oculus level that forms the Shrine Room ceiling and the shaft narrows, the steps winding upward to the playing cabin will be more utilitarian: galvanized steel in a bar-grating style. At the cabin level there will be additional rail details. (A ladder will remain the only way to access the belfry level. Older, rusted ladders are being removed.) New mechanical, plumbing and electrical systems also will be added inside, along with condensate piping to drain into the new subsurface system.

This first portion of the project, completed in fall 2019, pulled out and removed dirt and impurities from the exterior stone, leaving a visibly brighter, more radiant tower surface. This carefully orchestrated multistep cleaning process used gels, liquids and poultices to remove organic and inorganic staining, and to mitigate salt crystallization within the masonry walls that had resulted in efflorescence blooms on the exterior granite. Crews also repointed failing mortar joints where necessary, and they removed a waterproof coating of sealer that had been applied to the lower section of the exterior several years ago, unfortunately trapping moisture and causing additional Shrine Room deterioration.

Water damage in the 12-by-12-foot Shrine Room at the tower’s base had become serious, leaving the room’s marble and serpentine in very poor condition. The memorial tablet bearing the names of 34 NC State alumni who lost their lives in World War I was placed in offsite storage a few years ago because water was wearing away the names; a wooden facsimile bearing a photograph of the tablet took its place. The exterior sealer added a decade ago had caused even more deterioration in the marble walls, with chunks literally falling off. The entire room, including the plaque and benches, is being restored. The name of an additional alumnus more recently discovered to have died shortly after returning home from the war — due to catching the Spanish flu while serving overseas — will be added on a wall near the plaque. A new oculus level, inspired by ceiling designs of other World War I memorials, is being added. It replaces the ceiling with a higher domed and backlit marble one, incorporating natural lighting from above. New pendant and sconce lighting fixtures will reflect the historic period of the tower’s design. A new time capsule will be encased under the stairs.

The plinth — the platform raised about 3 1/2 feet above ground level, where one enters the door to the Shrine Room — was built in a way that allowed  water to pool below it, creating a problem with  moisture wicking upward through the masonry. The plinth has shifted slightly since it was installed a few years after initial construction, though the tower itself remains structurally sound. The platform’s cobblestone pavers, which have settled unevenly, are being removed (along with the concrete under them), and  a new subsurface drainage system will be installed with appropriate fill to replace wet plastic clays. The cobblestones will be moved to a new location at the site. The new plinth paving will be large slabs of pink Salisbury granite, the same type of stone used for the original pavers. Granite benches are being repaired and reinstalled.

A wide “ascending path” — less steeply sloped than a ramp — is being added on the south side to improve accessibility. While the Belltower’s footprint won’t really change, the project team will reconfigure the side nearest the Pullen Road parking spaces and will shift a flagpole. The ascending path will replace the granite steps on that side but match the plinth; these former plinth steps will be reused at the south end of the new path. It also will be accessed via steps with handrails and a small ramp near the parking area.

In recent years, crews replaced concrete at the lower plaza or concourse level with gravel. The original pavers had settled, cracked and deteriorated because of the water problems. The project team will reinstall concrete flatwork to match the historic scoring pattern, after upgrading the drainage system. There will be new decorative paving and bricking in some areas, such as around flagpoles and on the path to the Hillsborough Street stairs.

Lighting is being upgraded and made more efficient. The four exterior torchieres — each pedestal holds a bowl with four fixtures — have been redesigned to be more appropriate to the tower’s period of origin. New bronze bowls, mounted on the refurbished metal posts of the old fixtures, will have LED lights that will allow the tower to be lit both red and white. There will be new interior task and emergency lighting, and the belfry will gain white lighting. Existing lighting at flagpoles will be retained.

Five new geothermal wells drilled around the tower will anchor a well-water heating and cooling system to protect the new carillon and associated parts, and to keep carillonneurs and Shrine Room visitors comfortable in a conditioned space. This new HVAC system also will eliminate issues with condensation on the interior faces of the tower walls. Condensate will drain into new piping leading to the subsurface drainage system as part of the new plumbing infrastructure.

Other Utilities

Existing electrical equipment boxes that have been located under large trees southwest of the tower will move south into the brick paver walkway between Watauga Club Drive and the Holladay Hall parking lot. Power is being upgraded, along with security and data systems, and surge and lightning protection.

Most of the old “carillon” will be removed, with some portions of the equipment — such as one tubular bell cabinet — retained for display and others archived. There will be donor signage on the wall, and current plans call for the eventual installation of a small historic display and an interactive touchscreen with more information on the Belltower.

钟楼的顶部将建造一个弹簧管室或键盘弹室,就在钟楼的高度以下。它将有一个木制键盘,带有指挥棒和脚踏板,以及一个电子钟,在Holladay大厅有一个辅助控制面板。旧的钟楼将从那个地方移走。

工人们将拆除钟楼神龛室的天花板,并对纪念牌的现有框架进行轻微的重新设计,以便在钟楼内部安装通往钟楼室的楼梯。它们将是金属的,在神社房间里有一个更具装饰性的石头部分,并将取代目前为维护提供向上通道的狭窄钢梯子。神社房间将获得更高的部分天花板,并配有吊坠照明。

这部分项目包括其他项目,如安装一个新的HVAC系统,以保护carillon的木材,并为任何人提供舒适的演奏。计划在钟楼开口处增加防鸟屏。

换向和防止损坏

新大西洋承包公司(New Atlantic Contracting Inc.)和Walter Robbs Callahan & Pierce Architects PA的设计建造团队已经完成了结构、土壤、热像图和其他测试,以验证和记录现有条件和需求,并建立详细的设计解决方案、施工原理图、时间表等。大的决定(楼梯的类型)和小的决定(是的,2009年被闪电击中的西北角顶石上的小洞将被保留)已经做出。例如,该团队尽可能地遵循Deacy最初的蓝图、计划和愿景,并在选择新的灯具时忠实于钟楼的时代。

Lallathin指出,研究表明钟楼本身的结构状况良好,没有明显的横向移动或沉降迹象。carillon的安装相当简单。

然而,坏消息是,整个塔的混凝土、花岗岩、蛇纹石和大理石表面都受到了广泛的破坏,因此修复和确保未来的保护和稳定是当务之急。“渗水和问题有几个来源,”他说。

这些来源包括风驱动的雨水进入打开的窗户和钟楼舱口;地下水排水不足;湿气:由自然的季节冷却和加热循环产生的湿气;渗透通过恶化的护套和密封。解决方案包括室内百叶窗系统。

该项目还将涉及挖出并更换基座下的大部分填充材料。目前的粘土混合物能保持水分,并使其在砖石结构中聚集和上升,以至于几年前,塔周围开裂和沉降的铺路石必须用砾石取代。在升级排水系统后,项目团队将重新安装混凝土平板,以匹配历史评分模式。

当务之急是修复被严重损坏的大理石和神社房间里的其他材料,并修复储存中的纪念牌匾——几年前,它被一个木头和照片的复制品暂时取代,因为水正在慢慢地擦掉上面的名字。

项目团队计划为一些重大活动提供进入钟楼遗址的通道,包括戒指仪式和其他与毕业相关的活动,并将尽量减少项目在这些时候的影响。

一旦钟楼网站的工作开始,一个网络摄像头将允许北卡州立大学社区密切关注进展。

“这非常令人兴奋,”他说汤姆·斯塔福德他是负责学生事务的退休副校长,十多年来一直是Belltower之旅的领队。“它会很美——甚至更美。”
