About this file

This is a set of architectural drawings prepared by Evan Lloyd Associates, Inc. for the Illinois Secretary of State to address water infiltration issues at the Howlett Building, a historic structure located at 501 South 2nd Street, Springfield, Illinois. The project involves the installation of new storm windows on the 3rd floor library portion of the building to correct water infiltration at existing windows. The drawings specify the installation of eleven (11) new aluminum storm windows with 14-inch clear tempered glass panes, black anodized aluminum thermally-broken storefront frames, neoprene spacers, and stainless steel threaded rods with epoxy. The design includes a 12-inch air gap at sides and top with 12-inch neoprene spacers spaced at 3-foot 4-inch on-center intervals. The project also requires removal and reinstallation of existing bird netting, a 20-foot light pole (typical of 10), a 30-foot flag pole (typical of 2), and a steel surface-mounted handrail to facilitate construction access. The drawing set was dated December 5, 2025, with an expiration date of November 30, 2026, and includes a site plan, existing window elevation, section details, sill details, and storm window elevation views at various scales for construction reference.

The drawings specify that all existing loose paint must be removed and glass protected prior to installation, with a finishing system consisting of zinc-rich primer, epoxy intermediate coat, and epoxy top coat in a color to be selected by the owner from the manufacturer's full range. The work requires alignment with original mullions and installation of glazing from the exterior. Construction activities will occur in a brick and concrete courtyard area that must be protected during the work. No pricing, contract term, bid response dates, or award information is provided in the drawing set itself, as this is purely technical documentation supporting the project scope.
