This is an as-built drawing for a 3 Cell Mechanical Draft Hybrid Wood Cooling Tower designed for the Cooling Tower Project at NIST. The drawing is prepared by BDT Engineering and documents the completed construction specifications for a wood cooling tower system.

The cooling tower features three mechanical draft cells with hybrid design characteristics, as indicated by the detailed plan and elevation views. Key structural and mechanical components include wooden access ladders positioned at the tower entry points, partition walls, motor-driven fan stacks with associated piping connections (outlet and inlet piping for others), door mechanisms with rolling doors at the pit portion, access stair towers, lightning protection systems, and internal baffle configurations for water distribution. The tower includes provisions for 12.5 bypass piping with motor-operated valve installation. Foundation details indicate pit structure drainage with specified dimensions for spacing between cells and overall footprint measurements. The drawing references NIST Contract No. CT-1047/P122 and is identified as project 1306T3CT-1047 NISTDUAH(1), with revision dates noted as 3/27/09, 2/09/09, and 6/23/09. The document serves as a final record of the constructed cooling tower system's actual specifications and dimensions.
