This Addendum 1 is issued by the State of West Virginia Department of Administration, General Services Division, for Agency Request for Quote (ARFQ) Solicitation No. GSD2300000031 regarding Building 25 Concrete Repair. The solicitation seeks concrete repair services for Building 25, with delivery to the General Services Division in Parkersburg, West Virginia.

The addendum addresses four technical questions from prospective bidders, including clarification that the ramp at the corner of 4th and Green Street requires reconstruction in compliance with ADA guidelines using Type 6 ADA access, specifications for expansion joint materials similar to Sika Speed Dowel products, and confirmation that contractors are responsible for any additional concrete replacement costs resulting from damage beyond the original scope of work during stump removal operations.
The addendum includes a bid bond requirement with a minimum of 5 percent of the total bid amount, and a blank bid bond form is provided for vendor submission with the proposal. Supporting documentation includes detailed specifications for construction waste management and disposal, earth moving operations, concrete paving joint sealants, and cast-in-place concrete work. Concrete mixture specifications require a compressive strength of 4500 psi, 6 percent air entrainment, and a water-cement ratio of 0.45. An addendum acknowledgment form must be completed and submitted with the bid; failure to acknowledge addenda may result in bid disqualification. All provisions of the original solicitation and other addenda not modified by this addendum remain in full force and effect.

| PART 3 - EXECUTION |
| 3.1 FORMWORK |
| A. Design, erect, shore, brace, and maintain formwork, according to ACI 301, to support vertical, lateral, static, and dynamic loads, and construction loads that might be applied, until structure can support such loads. |
| B. Construct formwork so concrete members and structures are of size, shape, alignment, elevation, and position indicated, within tolerance limits of ACI 117. |
| C. Chamfer exterior corners and edges of permanently exposed concrete. |
| 3.2 EMBEDDED ITEMS |
| A. Place and secure anchorage devices and other embedded items required for adjoining work that is attached to or supported by cast-in-place concrete. Use setting drawings, templates, diagrams, instructions, and directions furnished with items to be ... |
| 3.3 STEEL REINFORCEMENT |
| A. General: Comply with CRSI's "Manual of Standard Practice" for fabricating, placing and supporting reinforcement. |
| 1. Do not cut or puncture vapor retarder. Repair damage and reseal vapor retarder before placing concrete. |
| B. Clean reinforcement of loose rust and mill scale, earth, ice, and other foreign materials that reduce bond to concrete. |
| C. Accurately position, support, and secure reinforcement against displacement. Locate and support reinforcement with bar supports to maintain minimum concrete cover of two inches (2”). |
| 3.4 JOINTS |
| A. General: Construct joints true to line with faces perpendicular to the surface plane of concrete. |
| B. Construction Joints: Install so strength and appearance of concrete are not impaired, at locations indicated or as approved by the Architect. |
| C. Contraction Joints in Slabs-on-Grade: Form weakened-plane contraction joints, sectioning concrete into areas as indicated. Construct contraction joints for a depth equal to at least one-fourth of concrete thickness as follows: |
| 1. Grooved Joints: Form contraction joints after initial floating by grooving and finishing each edge of joint to a radius of 1/8 inch. Repeat grooving of contraction joints after applying surface finishes. Eliminate groover tool marks on concrete ... |
| 2. Sawed Joints: Form contraction joints with power saws equipped with shatterproof abrasive or diamond-rimmed blades. Cut 1/8-inch wide joints into concrete when cutting action will not tear, abrade, or otherwise damage the surface and before concr... |
| D. Isolation Joints in Slabs-on-Grade: After removing formwork, install joint-filler strips at slab junctions with vertical surfaces, such as column pedestals, foundation walls, grade beams, and other locations. |
| 3.5 CONCRETE PLACEMENT |
| A. Before placing concrete, verify that installation of formwork, reinforcement, and embedded items is complete and that required inspections have been performed. |
| B. Deposit concrete continuously in one layer or in horizontal layers of such thickness that no new concrete will be placed on concrete that has hardened enough to cause seams or planes of weakness. If a section cannot be placed continuously, provide... |
| 1. Consolidate placed concrete according to ACI 301. |
| C. Cold-Weather Placement: Comply with ACI 306.1. |
| D. Hot-Weather Placement: Comply with ACI 301. |
| 3.6 FINISHING FORMED SURFACES |
| A. Rough-Formed Finish: As-cast concrete texture imparted by form-facing material with tie holes and defects repaired and patched. Remove fins and other projections that exceed specified limits on formed-surface irregularities. |
| B. Related Unformed Surfaces: At horizontal offsets, and similar unformed surfaces adjacent to formed surfaces, strike off smooth and finish with a texture matching adjacent formed surfaces. Continue final surface treatment of formed surfaces unifor... |
| 3.7 FINISHING SLABS |
| A. General: Comply with ACI 302.1R recommendations for screeding, re-straightening, and finishing operations for concrete surfaces. Do not wet concrete surfaces. |
| B. Scratch Finish: While still plastic, texture concrete surface that has been screeded and bull-floated or darbied. Use stiff brushes, brooms, or rakes to produce a profile amplitude of 1/4 inch in one direction. |
| 3.8 CONCRETE PROTECTING AND CURING |
| A. General: Protect freshly placed concrete from premature drying and excessive cold or hot temperatures. Comply with ACI 306.1 for cold-weather protection and ACI 301 for hot-weather protection during curing. |
| B. Evaporation Retarder: Apply evaporation retarder to unformed concrete surfaces if hot, dry, or windy conditions cause moisture loss approaching 0.2 lb./sq. ft. x h before and during finishing operations. Apply according to manufacturer's written ... |
| C. Cure concrete according to ACI 308.1, by the following method: |
| 1. Curing and Sealing Compound: Apply uniformly to slab indicated in a continuous operation by power spray or roller according to manufacturer's written instructions. Recoat areas subjected to heavy rainfall within three hours after initial applicat... |
| 3.9 CONCRETE SURFACE REPAIRS |
