Description | The Scope of Work shall include, but not be limited to, all work shown and listed in the Project Documents and Specifications. The Contractor is required to provide a complete job as contemplated by the documents and specifications, which are a part of this bid package. The Contractor shall furnish all labor, supervision, materials, power, tools, equipment, supplies, permits and any other means of construction necessary or proper for performing and completing the Scope of Work, unless otherwise specifically stated. A. Project consists of structural stabilization of the historic masonry/concrete at the Ammunition Bunker portion of the West Martello Tower. The West Martello Tower is a National Register historic site. All work activities must be undertaken with sufficient care to protect this historic resource and must be supervised by personnel who are familiar with the Secretary of Interior’s Standards for Rehabilitation and have been pre-qualified under General Specifications, Section I, Bidding Conditions; Section II, Contractual Conditions; and Section III, Forms. B. The work will include, but not necessarily be limited to, the following items: Restoration of historic ammunition bunkers dating from circa 1862. The hairline cracks should be injected with epoxy and the larger cracks filled with a flowable corrosion inhibiting repair mortar. The wall areas that are spalling should have the loose concrete removed and replaced with a corrosion inhibiting repair concrete. The bottoms of the ammunition bunker slabs are in poor condition, but due to their significant thickness, are stable. To repair them, all loose concrete needs to be removed and the existing reinforcing cleaned of corrosion and supplemental reinforcing added with the new steel mat connected to the upper main slab, and new concrete placed at the bottom of the slabs. The bottom of the slabs should be board-formed to match the walls and existing slab bottoms, and the concrete should contain a corrosion inhibitor and should be selfconsolidating to aid in placement. The middle ammunition bunker should have the delaminated slab bottom concrete that is still in place removed, or the bunker should not be used for storage until the slab is repaired. The expansion joints need to be cleaned of debris and filled with sealant and the exposed corroding reinforcing drilled out and patched with a corrosion inhibiting repair mortar. The hairline cracks should be injected with epoxy to weatherproof them. | ||||||||||||||||||||||||||||||||
