Site restoration and cleanup will not be measured or paid separately but shall be included in the unit prices for each bid item. Partial payments will not be made on any bid item until the restoration and cleanup associated with that item is satisfactorily complete and acceptable to the Project Manager.

Article 2 – Special Provisions2.27 REMOVE AND REPLACE CONCRETE BALUSTERS

The City will mark or otherwise designate the concrete balusters to be removed and replaced. Cut rebar flush with the cap and base. Clean and remove debris, spalling, and loose concrete. The new concrete balusters shall match the existing balusters and shall be reinforced with rebar in the vertical axis. Secure the new balusters in-place using non-shrink grout or mortar at top and bottom of balusters using CDOT approved product.

2.28 PATCH AND SEAL CRACKS IN BALUSTERS

The City will mark or otherwise designate the concrete balusters exhibiting extensive cracking and/or missing concrete which shall be repaired. Exposed rebar shall have rust removed prior to sealing or patching of balusters. Contractor shall determine the most appropriate means to repair the balusters through one or both of the following methods:

2) Fill cracks in balusters with concrete crack sealant approved by CDOT product list.

Any balusters marked for repair that have damage too extensive, shall be brought to the attention of the Project Manager for complete replacement.


Article 2 – Special Provisions2.29 REPAIR EXPANSION JOINT PLATE

Existing expansion joint plates on the eastside sidewalk shall be repaired such that the existing tripping hazards are removed, and the sidewalk transitions are in compliance with ADA requirements. 2.30 REPLACE EXPANSION JOINT PLATE Sawcut and remove all unsound concrete in or around the area to be repaired. Use proper preparation geometry to ensure a level "shelf" on which to apply the EmcreteII elastomeric concrete. The substrates must be perfectly clean and dry prior to installation. Install side forms where needed to contain the Emcrete II. (IMPORTANT: the Emcrete II material is self-leveling. Forms must be tight to the substrate or sealed to prevent leakage of the material through the forms). Apply Sikadur® 32 HiMod primer to concrete areas that will receive the Emcrete II. If concerned about possible spillage or drips, mask-off any adjacent deck or other surfaces with duct tape and construction paper.

Pour nosing material into the blockouts. Trowel lightly while still curing to achieve consistent finish or allow the Emcrete II to self-level and cure as is.

Remove all contaminants by sandblasting or grinding to ensure a thoroughly clean and sound substrate for the full sealant depth. DO NOT use a wire wheel as this will polish the substrate and cause bond-failures. Install BEJS-Pedestrian System by EMSEAL per the manufacturers installation instructions. Install 3/8- inch diamond plate steel coverplate such that the plate meets ADA requirements.


Article 2 – Special Provisions2.31 REPAIR BRIDGE DECK SPALLING

Clean and patch areas of delamination in the edges of the bridge deck above the bike path and railroad tracks. The impending spalls in the concrete bridge decking are directly above the private road in Span 4. There is also an impending spall on the north edge of the deck directly above the pedestrian path in Span 2. Repairs shall be made in accordance with CDOT Section 601.

See RFQ for modifications to Section 601.12.


Article 2 – Special Provisions2.32 REMOVE AND REPLACE 4-INCH SIDEWALKS

Remove and replace approximately 150 SF of 4-inch concrete sidewalk on the east side of the bridge approach from the B Street side. Quantities and location to be verified by the Contractor.

Contractor shall be aware that 11 existing 6-inch diameter phone conduits are installed in the bridge deck and under the sidewalk full length west side.

2.33 SIDEWALK EDGE GRINDING

At a minimum, the grinding shall be any vertical displacement in the path of travel of ¼” or greater. At a maximum, a 2-inch vertical displacement may be repaired by grinding. Over 2-inches must be repaired by replacement.

Grinding shall be performed by a dry hand grinder with an attached vacuum to contain the generated concrete dust. For larger grinds the initial removal may be performed using a scarifier with attached dust control, with the final surface completed with the hand grinder.

Completed grinds shall be smooth and sloped back at a minimum of a 1:8 slope.

The completed grind shall be squared off at the back to allow for a clean look. The concrete on the other side of the grind should be left untouched. The finish grind should not be slippery. It should have about the same coefficient of friction as the undisturbed concrete surface.

Article 2 – Special Provisions2.34 CLEAN JOINT AND REPLACE STRIP SEAL

Clean dirt and gravel out of strip seal expansion joints at Pier 3 and Pier 8 with compressed air. Install BEJS Joint System by EMSEAL per manufacturer’s recommendations.
