The ProMedica Museum of Natural History at The Toledo Zoo & Aquarium Winner of 2019 Build Ohio Award

2019 Build Ohio Renovation Award

A. A. Boos & Sons Construction

The Museum of Science at The Toledo Zoo was a Works Progress Administration project, built in 1933 with local materials recycled into an indoor theater and exhibit showplace. A treasure of hand-carved workmanship in both stone and fitted timbers, the Museum’s load-bearing masonry walls measure up to 18-inches thick and support a Spanish tile roof. The Museum hosted a wide variety of exhibits through the 1980s, then transitioned into offices and research space. In 2015, the Zoo created a master plan which included bringing the structure into code-compliance and back to life as a vibrant, exciting architectural treasure.


Transforming the WPA-era museum into an entirely new visitor experience created major challenges for A.A. Boos & Sons, general and interior trades contractors for the project. To carry the loads of today’s visitors, displays, water features and exhibits, the firm had extensive shoring engineered to brace the structure, added 1,245 pieces of structural steel, poured 650 cubic yards of structural concrete and 85 cubic yards of exhibit Gunite. Since original columns do not align from one floor to the next, this shoring was also critical in the creation of 15 significant openings made in load-bearing brick walls as well as the re-alignment of the first floor. Over eighty-percent of the basement was removed and A.A. Boos excavated 1,200 cubic yards of dirt through standard (3′ x 7′) doors while removing and lowering the theater’s sloped floor to meet code and accessibility requirements. Over 300 field work orders were completed with well over one hundred additional tasks done the week the Museum opened to the public. A.A. Boos self-performed 45,000 man-hours of work with no lost-time injuries while protecting the architectural integrity of the Museum, finishing without a single crack in the brick structure, ornate stone detailing or treasured woodwork.

Kudos

Thank you for the hard work and effort you put into our submission. It was evident by the way everyone perceived our project at the banquet that the entry was professional and met all the criteria. You truly have a gift when it comes to delivering a project's history and uniqueness.
