到2018年底，俄亥俄州的一项耗资4.29亿美元的高速公路工作，绕过辛辛那提和哥伦布之间的速度驾驶时间，是该州最大的道路项目，也是其首次作为公私合作伙伴关系。尽管P3方法正在加快俄亥俄州退伍军人纪念高速公路/823州项目的完成，但参与者说，建筑质量保证要求远非容易。
The Dragados-led project team decided that no off-the-shelf software could handle the project data and reporting requirements of the Ohio Dept. of Transportation. It hired quality oversight consultant CH2M to custom-develop the Construction Quality Records System (CQRS), a tool for use with CH2M’s existing CH2Mobile data collection system to document and track how observed work conforms to contract requirements, says Bryan Parsell, the firm’s construction services project manager.
“It is difficult to claim something is nonconforming unless you can … provide objective evidence,” Parsell says. CQRS is built on base maps from GIS software vendor Esri.
When nonconforming work is identified, the tool logs and tracks the issue. Personnel can use mobile devices to collect data, including marked-up photos tagged to stations and offsets. Submitted information is saved to the cloud and a secure CH2M server in Denver. The mobile data collection system works online or offline, but connectivity is assured by the project’s 16-mile-long, solar-powered WiFi network.
The information is shared via a browser from CH2M servers. When the database is updated, any impacted mobile form lookup lists are pushed out to inspectors’ devices. Form submissions have associated geolocations, so data can be displayed on a map. The project’s more than 900 assets have associated GIS shapefiles, which lets their status be displayed on color-coded maps. “Since all collected data has been associated to a GIS shape, you can graphically display the results, which is pretty cool,” Parsell says.
团队的质量控制小组必须提供证据表明100％的工作是符合符合的。预计该系统将通过其35年的维护义务支持P3。
David Yardy, a CH2M software architect who helped develop CQRS, says CH2Mobile is used on 30 other CH2M projects, and tools similar to CQRS can be built for it to be used for many kinds of data tracking.
