Specifications include, but are not limited to: A. A full shelter is assumed to ship as a complete shelter with all necessary parts, glass, hardware, and a three-seat bench that is ready for installation as a complete unit. B. To maintain a uniform inventory the Contractor shall supply MDOT MTA with Enseicom shelters or an approved equal. C. Currently, the MTA primarily uses two types of Enseicom shelters, Barrel Single Shelter (Model S 040) and Cantilever Shelter (Model S 010). Both models are available with and without advertisement panels. Both models are also available with and without self-contained solar lighting assemblies. During the term of this contract MTA may request other models available, such as an extended length shelter or shelters designed to fit in specific locations. D. An approved equal must use tempered side and rear glass panels with the exact measurements of the existing MTA shelters. Approved equals must include four leg (Barrel) shelters and two leg (Cantilever) shelters. See Appendix 3 for drawings illustrating the current shelters. “Cantilever” shelters have two legs in the rear of the shelter and in addition to the standard side glass panel must be able to utilize side panels in different width. For uniformity, at a minimum the cantilever shelter must be able to use 36” wide side panels to allow for installing in confined locations. The standard side glass panel for the barrel shelter is 54-1/8” x 84-15/16” x 3/8” thick. The standard/uniform rear glass panels for both the Barrel and the Cantilever shelters are 41-3/16” x 81” x 3/8” thick. Additionally, approved equals must be available with and without full size add panels and must match or exceed the following: 1.
