Engineering a vehicular tunnel ceiling system to meet required structural loads and offer aesthetic durability in a harsh environment has been accomplished with a novel design involving large Ceramicsteel laminated panels. Several technologies, including porcelain enameling (steel and aluminum), prefabricating (metal), precasting (concrete), using adhesives (lamination), and applying sealants (silicone) were carefully integrated. System design criteria for panels, for example, initial vehicle traffic and structural loads, seismic and other safety considerations, surface appearance (color, gloss, flatness, and size tolerances), and durability (salt watel, diesel exhaust, cleaning solution, and abrasion by brushes) are treated. This paper discusses the engineering and manufacture of over 22 000 panels, typically weighing 800 lb each, that are now installed in Boston's 1.5-mi Central Artery (Ted Williams) Tunnel.
