ITEM 1 - DESCRIPTION OF WORK

1.1 Background: William Howard Taft National Historic Site preserves the birthplace and boyhood home of William Howard Taft, the nation's 27th President and 10th Chief Justice of the U.S.

Supreme Court. The site was established in 1969 to give visitors an understanding of the environment that shaped Taft's character and philosophy. The goal of this project is to remove 170 feet of wooden safety railing and replace it with steel railing providing a better and longer lasting safety railing system.

1.2 Work Covered by the Contract Documents:

A. Project Location: 2038 AUBURN AVE, CINCINNATI, HAMILTON COUNTY, OHIO

B. Work consists of: Work consists of: Removing Existing Wooden Railing and Installing New Gray Painted Railing as Described.

1. This item consists of removing approximately 170 linear feet of wooden treated railing on the east side of the carriage path. The Railing includes 24 wooden posts to be fully removed from the ground as the holes are to be reused for the new railing post structure. All measurements to be field determined and verified. New railing posts cannot be dug, and the existing locations must be reused.

2. Install approximately 170 feet of steel gray painted railing to match design of the existing railing on the east end of the carriage path as seen in photos below. The railing includes 24 posts to be installed in pipe sleeves as described in drawing below. The Existing post holes from the prior railing posts are to have cemented pipe sleeves for the new railing post structure. This new railing is to match existing railing to the east of the carriage path and to be removable to be reutilized at a future date (see Appendix B & C for joints and attachment details). The height of the railing to be no lower than 42” and no higher than 44”. The vertical square spindles will match the existing on the railing east of the carriage trail. All joints must maintain a level and even appearance. All Joints SHALL be free of welding splatter, sharp edges that could pose a threat to cuts and other personal injury and all sections must be fully painted with field painting allowed. All field painting must be done to preserve the surrounding environment. NO Spraying will be allowed, all work is to be done via rollers or brushes. All measurements to be field determined and verified.

3. The section of railing to the west of the Education Center is to have a lockable gate section attached to the posts installed in the existing holes. All measurements to be field determined and verified.

4. The railing sections going to the brick wall at the entrance cannot have posts dug. They will be anchored to the brick structure with painted steel plates or brackets, and any require spacers to attach to the vertical posts in these locations. The sections that are adjacent to the existing fence will attach to the existing fence.

Revision 25 Feb 2025

5. The section of fencing that runs behind the equipment shed is to be terminated to east and west side accordingly. For SAFETY reasons due to the stability of the soil behind the equipment shed the fence now needs to be terminated to the equipment shed. See attached pictures for locations.

- The fence behind the equipment shed is to be removed and not replaced. Holes (locations shown with red circles) are to be filled with gravel matching existing gravel.

Include complete information for the fabrication and erection of the structure's components, including the location, type, and size of bolts, welds, member sizes and lengths, connection details, blocks, copes, and cuts. Use AWS A2.4 standard welding symbols.

Clearly highlight any deviations from the details shown on the contract drawings highlighted on the fabrication drawings. Explain the reasons for any deviations from the contract drawings.

PART 2 PRODUCTS

2.1 FABRICATION

Preassemble items in the shop to the greatest extent possible. Disassemble units only to the extent necessary for shipping and handling. Clearly mark units for reassembly and coordinated installation.

For the fabrication of work exposed to view, use only materials that are smooth and free of surface blemishes, including pitting, seam marks, roller marks, rolled trade names, and roughness.

Remove blemishes by grinding, or by welding and grinding, before cleaning, treating, and applying surface finishes, including zinc coatings.

Provide railing and handrail detail plans and elevations at not less than 1 to 12 scale 1 inch to 1 foot. Provide details of sections and connections at not less than 1 to 4 scale 3 inches to 1 foot. Also detail setting drawings, diagrams, templates for installation of anchorages, including concrete inserts, anchor bolts, and miscellaneous metal items having integral anchors.

Use materials of size and thicknesses indicated or, if not indicated, of the size and thickness necessary to produce adequate strength and durability in the finished product for its intended use.

Work the materials to the dimensions indicated on approved detail drawings, using proven details of fabrication and support. Use the type of materials indicated or specified for the various components of work.

Form exposed work true to line and level, with accurate angles and surfaces and straight sharp edges. Ensure that all exposed edges are eased to a radius of approximately 0.8-millimeter 1/32 inch. Bend metal corners to the smallest radius possible without causing grain separation or otherwise impairing the work.

Weld corners and seams continuously and in accordance with the recommendations of AWS D1.1/D1.1M. Grind exposed welds smooth and flush to match and blend with adjoining surfaces.

Form the exposed connections with hairline joints that are flush and smooth, using concealed fasteners wherever possible. Use exposed fasteners of the type indicated or, if not indicated, use countersunk Phillips flathead screws or bolts.

Provide anchorage of the type indicated and coordinated with the supporting structure. Fabricate anchoring devices and space as indicated and as required to provide adequate support for the intended use of the work.
