SECTION 01 10 00

DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The Visitor Center and adjacent pedestrian bridge were constructed in 1959-60. The building underwent a major remodeling and reconfiguring in 1995. The original “breezeway” was an exterior space on both levels and wrapped around the northeast corner of the building. It is a steel tube frame structure with concrete planking. The breezeway was enclosed at the lower level as part of the

1995 improvements and consists of wood-framed exterior walls with wood siding, concrete topping with internal drainage of the exterior walkway above and wood stud guardrail with wood cladding and limestone cap, which replaced a metal guardrail. This solid wall guardrail does not afford equal access to views. The enclosed lower level, approximately 975 GSF, is used for storage and is referred to as the

“wrap-around.” It has endured degradation of the exterior envelope due to water infiltration. The pedestrian bridge located to the north of the Visitor Center will be renovated due to degradation of the substructure. This will entail removal of existing substructure, removing the guardrail which is to be reinstalled, and retaining the existing cast-in-place concrete superstructure. New precast concrete substructure and topping is to be provided. Correction of these deficiencies is the goal of the Project.

1.2 Work Covered by the Contract Documents:

A. Project Location: Effigy Mounds National Monument, 151 IA-76, Harpers Ferry, IA 52146.

B. Work consists of: The work for this Project consists of selective demolition and reconstruction of the northeast corner of the Visitor Center at the exterior structured walkway of the Main Level and storage area of the Lower Level directly below. The existing steel structure will be retained, and will support new steel beams, metal deck and insulated concrete topping. Exterior walls of the wrap-around will be demolished and replaced with infill metal stud walls with wood siding and a new exterior door at the north. The new exterior walkway will be provided with a new metal railing. The interior work consists of new walls and doors, new lighting, reinstallation and modification of the automatic sprinkler system, reinstallation and new electric unit heaters, and other associated work.

C. All work will be performed under a single contract.

Period of performance: Work shall be completed within 365 calendar days of the start date provided on the Notice to Proceed. The period of performance is inclusive of 21 weather days.

ITEM 2 - EXISTING UTILITIES

2.1 Existing Utilities: Notify Contracting Officer (CO), Contracting Officer’s Representative (COR) and utility companies to coordinate proposed locations, times for excavation and request location services prior to any digging operation.
