1.6.4 Temporary Flood Protection (TFP)

Prior to any work commencing on the concrete floodwall, the contractor shall have the sheet pile portions of the temporary flood protection (TFP) in place for the portion of floodwall being constructed. The minimal cellular barrier portions of the TFP shall be deployed as triggered by either river forecast or season. Note that the sheet pile tie-ins between the floodwall and TFP will require a limited amount of demolition of the existing floodwall. The sheet pile tie-ins shall be performed only once the majority of the TFP is already in place such that lack of complete flood protection is not outside of the river forecast range of 5 days. The temporary flood protection shall be provided in three distinct phases as outlined on the contract drawing and in Part 3 of this specification.

Temporary flood protection shall be placed in accordance with Section

01 53 00.01 12 TEMPORARY FLOOD PROTECTION.

1.6.5 Demolition

Demolition of the concrete floodwall shall not commence prior to the temporary flood protection being in place. No exceptions.

1.6.10 Removal of Temporary Flood Protection (TFP)

Once the floodwall construction is complete for a given phase, the temporary flood protection can be removed in a phased approach with the approval of the Contracting Officer. Special emphasis is required at the tie-ins between the TFP and the new floodwall. The final monolith(s) constructed during each phase shall be at the the tie-ins because it could require removal of a small segment of TFP that is in the footprint of the new monoliths. Only one tie-in monolith can be constructed at any given time. When removing the TFP for phase tie-ins the river forecasts (long term and short term) shall be favorable for construction (i.e. Mississippi River gage at Caruthersville not exceeding 3 feet below the bottom of the footing excavation). Construction of the tie-in monoliths shall be completed without delay. The Contractor shall keep approximately 1200 linear feet of cellular barriers (4-foot height), plus infill, on site in the event that the river levels rise above the base of the floodwall while the tie-in monolith is being constructed. Sheets for the TFP alignments that run parallel to the permanent floodwall can be pulled and reused in another phase of construction. The TFP sheets at the floodwall tie-ins, the levee tie-ins and within 50 feet of the casino structure are to remain embedded and cutoff at least 3 feet below the finished ground surface or below the floodwall foundation reinforcement. The areas shall be backfilled in accordance with Section 31 41 16.00 12 STEEL SHEET PILING.

PART 3 EXECUTION

3.1 Floodwall Construction Sequencing

Floodwall construction sequencing phases as indicated on contract drawings can be completed in any order. However, recall from Paragraph 1.6.2, the over-the-levee ramp shall be constructed prior to any floodwall or sheetpiling for temporary flood protection construction commencing within the Bunge Phase. The designations given for each phase are for identification purposes only. The concrete floodwall shall be constructed in three distinct phases as indicated on the contract drawings, and as described below:

(1) Bunge Phase: Begins at the northernmost end of the floodwall near Bunge Grain Facility (Monolith 1) and extends to southern side of the gate opening at Ward Avenue (Monolith 21). Traffic that usually utilizes Ward Avenue as primary access to the riverside shall be directed to use the floodwall openings at Walker Avenue or Bushey Avenue during this phase. The contractor shall maintain public access at all other gate openings not within this phase. In order to begin this phase, the ramp over the levee shall be complete with fill and pavement so that access is provided to the grain facility once the Carleton Avenue opening is permanently closed.

(2) Reynolds Park Phase: Begins at the southern end of the gate closure at

SECTION 01 11 00 Page 5

Ward Avenue (Monolith 22), and extends to southern side of the gate opening at the casino boat ramp (Monolith 43). During construction of this phase, the Ward Avenue gate opening that was newly constructed in the Bunge Phase shall be made available for public use to access the riverside of the floodwall. The contractor shall maintain public access at all other gate openings not within this phase.

(3) Century Casino Phase: Begins at the southern side of the gate opening at the casino boat ramp (Monolith 44) and extends to the southern end of the floodwall (Monolith 69). This phase includes an existing pedestrian walkway that extends from Century Casino, over the existing floodwall. See paragraph 3.3 of this specification for special considerations for this phase of construction.

See contract drawings for approximate locations of the beginning and end of the temporary flood protection tie-ins for each phase described above. The contractor shall submit, with his phasing plan as required by 01 53 00.01 12 TEMPORARY FLOOD PROTECTION, any proposed deviaitons from the phase boundaries as outlined above for approval.

3.2 General Requirements

The contractor shall follow these general requirements:

(1) Work shall be scheduled and accomplished in a manner that maximizes public use of the openings in the floodwall.

(2) When construction is not active at a gate opening, the opening shall be safely secured and made available for public use. The exception to this requirement will be any curing periods required immediately following placement of concrete at the gate monoliths.

(3) Once construction has commenced at the site, the contractor shall schedule work in a manner to complete foundations within a reasonable time to minimize closure time of the gate openings.

3.3 Specific Requirements

The existing pedestrian walkway located at Century Casino shall remain in place during construction. The Contractor shall coordinate with the casino, and provide at least a 30 day notice prior to commencing work on the Century Casino Phase of construction. Care shall be taken to initiate no damage to the existing walkway. Press in methods shall be used for advancing sheet piles within 50 feet of the casino structure.
