Metropolitan Transit Authority / New York, New York
The Metropolitan Transit Authority (MTA) retained Mott MacDonald to develop a Tunnel Information Management System (TIMS) to collect and manage construction management and inspection data for four soft ground tunnels beneath Queens’ Sunnyside Yards, developed as part of MTA’s East Side Access Project.
Mott MacDonald worked closely with the client to develop a flexible, easily customized TIMS for soft ground tunnels.
We developed a remote and secure data entry application on HP netbooks, allowing the shift inspector to do remote data entry followed by an upload function to add inspection reports onto an online application for supervisor approval, via Citrix. Individual inspection reports are stored in XML format and all uploaded reports are stored on an Oracle database.
- Collection of shift data includes contractor activities, high-level ring production detail & labor and equipment counts
- The TIMS includes a Shift Summary Report and a subset of reports for assessing progress, availability & utilization of the tunnel boring machine
- Key project challenges included special Citrix default print & MTA Internet proxy settings to meet COM & end-user expectations
