VERRAZANO NARROWS BRIDGE APPROACH RAMP VN-80C

On behalf of the owner Metropolitan Transportation Authority Triborough Bridge and Tunnel Authority, Atema performed a deep-dive qualification audit on a major bridge fabricator that was under consideration to supply to the project. Atema assessed the ability of the fabricator to meet specific contract requirements, the owner’s specification and the presence of a sustainable quality management system processes and controls. Ultimately, the fabricator was not qualified to provide product based on audit and findings presented.

JOHNSON STREET BRIDGE REPLACEMENT: CITY OF VICTORIA, BC CANADA

This new signature bascule for the City of Victoria, BC is a challenging design presenting numerous fabrication and inspection issues. As fabrication consultant Atema contributed to specification and design changes, shop drawing reviews, development and review of quality oversight plans and inspection and test plans and training on code and specification compliance.

PROCESS IMPROVEMENT: SHANGHAI GRAND TOWER

Atema has assisted companies of different sizes, from as little as 14

employees to as many as 4,000, examining their material flow patterns, handling frequency, or equipment utilization to improve productivity. The companies utilizing this service before planning a move or expansion see the benefits of process improvements multiply. An example: With Atema’s help, The Shanghai Grand Tower shifted a bottleneck process to a production point where impact was minimized. The number of times a piece required handling was reduced, and other process adjustments increased assembly capacity by 30%.
