西雅图市中心科布车库混凝土与外墙修复工程完工
华盛顿州金县西雅图市市中心的科布车库修复工程近日完工。据工程承包方10月26日发布的公告，位于西雅图联合街315号的科布车库完成了大规模混凝土修复、外墙修复和防水工程，项目由西部专业承包商西雅图分公司担任总承包商，为业主尤尼科地产服务，顾问方为进化建筑事务所。
工程内容包括混凝土和裂缝修复、密封胶拆除更换、以外墙硅酮涂料清洗涂装外墙，以及清洗涂装金属格栅和安装艺术品锚固件与轨道。项目最大的挑战是工期：工程必须在国际足联施工禁令开始前完成，团队在业主和西雅图市政府的协助下，两周内就拿到了施工许可。
施工中还遇到材料延迟和艺术品安装进场协调问题，工人沿墙面挂起三层作业平台以保证进度。艺术品安装环节，团队开发了专用模板，使约120英尺长的外墙锚固件和轨道保持一致水平，全长误差仅四分之一英寸。项目经理瑞安·道尔顿表示，项目需要大量协调才能按期交付。
Concrete and Facade Restoration Completed at Cobb Garage in Downtown Seattle
The restoration of the Cobb Garage in downtown Seattle, King County, Washington, was recently completed. According to an announcement issued by the contractor on October 26, the Cobb Garage, at 315 Union Street in Seattle, underwent large-scale concrete repair, facade restoration and waterproofing; the project was led by the Seattle branch of Western Specialty Contractors as general contractor, for owner Unico Properties, with Evolution Architecture as consultant.
The work included concrete and crack repairs, sealant removal and replacement, cleaning and coating the facade with a silicone coating, cleaning and coating metal grates, and installing artwork anchors and rails. The project's biggest challenge was the schedule: the work had to be finished before the FIFA construction moratorium began, and with help from the owner and the City of Seattle, the team obtained the construction permit within two weeks.
The project also ran into material delays and coordination issues for artwork-installation access; workers hung three tiers of staging along the wall to keep to schedule. For the artwork installation, the team developed a dedicated template that kept about 120 feet of facade anchors and rails level and consistent, with a variance of only a quarter inch over the full length. Project manager Ryan Dalton said the project required a great deal of coordination to deliver on time.
