STATEMENT OF WORK

LOCK 8 WINTER MAINTENANCE – DEWATERING

CONCRETE SUPPLY AND DELIVERY

SCOPE OF WORK

1. General. The work shall consist of the concrete being supplied for Lock 8 Winter Maintenance. A total of approximately 130 cy3 shall be delivered and placed by methods of pumping to Lock and Dam No.8.

This amount could vary as the final inspections cannot be completed until the lock chamber is emptied in early December. The placement areas include the upstream bulk head supporting blocks, the downstream bulk head sill beam, and the vertical concrete repair located on the Land and Intermediate wall inside the lock chamber. The quote shall provide for all labor, equipment, materials, and supplies necessary for this work.

2. Construction Schedule. The concrete supplier shall coordinate with the Government Representative for exact placement times, dates and quantities. However, tentative delivery dates are set for mid January 2014 through early March 2014.

3. Site Location.

U.S. Army Corps of Engineers St. Paul District Lock and Dam No. 8 4405 Highway 35 (Box 10) Genoa, WI 54632-0265

4. Submittals. The following shall be submitted to the Government for approval no later than 10 days after the award of contract.

1. Concrete Mixture Design A mix design shall be submitted for each concrete mix to be used on the project. Each mix design shall list the proportions by weight of cement, weight or volume of water, weights of aggregates in a saturated surface-dry condition, and type, quantity, and name of admixtures per cubic yard of concrete. All materials included in the mixture shall be of the same type and from the same source as will be used on the project. Each mix shall be accompanied by evidence that demonstrates the mix will produce concrete having the characteristics and quality as specified:

a. Mix Design Study Submit a mix design study complying with ACI 211.1 conducted in the past 12 months. The mix design shall be completed by a testing laboratory complying with ASTM C 1077. For SCC (Self-Consolidating Concrete) submit evidence of the design mix for this project. The evidence shall include test data from the Slump Flow Test including the Visual Stability Index (VSI) per ASTM C 1611 and its appendix. A registered professional engineer knowledgeable and familiar with self-consolidating

b. Project Data Project data or mix design studies shall be obtained for the exact mix as submitted. Minor mix alterations or substitutions may be accepted if approved by the Contracting Officer in writing. Any alternations or substitutions shall be clearly identified, and shall be accompanied by recommendations from the admixture supplier or a registered professional engineer indicating the expected effects on the concrete.

2. General Concrete Requirements The concrete shall be a Self-consolidating concrete (SCC), that is able to flow under its own weight and completely fill the form work, even in the presence of dense reinforcement without the need of any vibration while maintaining homogeneity. The concrete shall be composed of a cementitious material, water, fine and coarse aggregates, and admixtures. The admixtures shall include High Range water reducers (HRWR), which are an essential component of SCC to provide the necessary work ability; viscosity modifying agents (VMA) for stability and air entraining admixtures (AEA) to improve the freeze-thaw resistance. The design compressive strength as determined by ASTM C 39 shall not be less than 4,500 pounds per square inch in 28 days. Water-cement ratio shall not exceed 0.40. The maximum water-cement ratio will be determined by the weight equivalency method as described in ACI 211.1 (cement plus pozzolan, silica fume, and ground granulated blast furnace slag). This W/C ratio may cause higher strengths than required. The cementitious material content shall be a minimum of 500 and a maximum of 620 pounds per cubic yard. Materials shall meet the requirements of the respective publications and other data specified below:

a. Slump Flow: For SCC (self-consolidating concrete) the slump flow of concrete is identified as the flow of concrete as measured by the Slump Flow Test. The slump flow should be between 22 and 28 inches, with a visual rating of static stability equal to zero or one as determined by the Visual Stability Index (VSI) as described in ASTM C 1611 and its appendix.

b. Admixtures: Admixtures to be used on the project shall be included in the mix design submittals. Accelerating admixtures shall be used only when approved in writing.

c. Air Entrainment: All concrete shall be air entrained to contain between 4-1/2 and 7- 1/2 percent total air.

d. Aggregates:

i. Size of Coarse Aggregate: Nominal maximum size coarse aggregate shall be 3/4-inch.

ii. Composition: Fine aggregate shall consist of natural sand, manufactured sand, or a combination of natural and manufactured sands. Coarse aggregate shall consist of gravel, crushed gravel, crushed stone, or a combination thereof.

iii. Quality: The aggregate particles shall be clean, hard, unweathered, and uncoated. The shape of the particles shall be generally cubical or spherical.

Where required, fines shall be removed from the aggregates by adequate washing. The aggregates as delivered to the mixer shall meet the quality requirements of ASTM C 33, table 3 for the appropriate type or location of concrete construction for use in a severe climate.

e. Cementitious Materials: Cementitious materials shall be portland cement, or portland cement in combination with pozzolan or ground granulated blast furnace slag. Optional pozzolan replacement of cement shall be limited to 20 percent of the total cementitious material of a mix by weight. Cementitious materials shall conform to appropriate specifications listed below. Use of cementitious materials in concrete which will have surfaces exposed in the completed structure shall be restricted so there is no change in color, source, or type of cementitious material.

i. Portland Cement: ASTM C 150, Type I with a maximum 15 percent amount of tricalcium aluminate, or Type II.

ii. Pozzolan (Fly Ash): ASTM C 618, Class C or F with the optional requirements for multiple factor, drying shrinkage, and uniformity from Table 3 of ASTM C 618.

iii. Ground Granulated Blast – Furnace (GGBF) Slag: ASTM C 989, Grade 120.

5. Method of Placement. The concrete pump shall conform to the following specifications: The pipeline shall be rigid steel pipe or heavy-duty flexible hose. The inside diameter of the pipe shall be at least 4 inches. The distance to be pumped shall not exceed limits recommended by the pump manufacturer. The concrete shall be supplied to the concrete pump continuously. When pumping is completed, concrete remaining in the pipeline shall be ejected without contamination of concrete in place. After each operation, equipment shall be thoroughly cleaned, and flushing water shall be wasted outside of the forms and in compliance with the approved environment protection plan.

6. Safety. All work shall be in conformance with the Corps of Engineers Safety and Health Requirements Manual EM 385-1-1 (15 September 2008 edition).

7. Site Restoration and Cleanup. The contractor shall clean up and dispose of all job related debris in accordance with all state and local laws and ordinances. All surface areas damaged by the Contractor’s operations shall be restored.

8. Measurement and Payment. Payment shall constitute full compensation for furnishing all labor, materials, equipment, and incidentals required and performing all work in a satisfactory manner and in accordance with the requirements described herein.

a. All invoices shall be sent to:

USACE Finance Center St Paul District (B6) 5722 Integrity Drive Millington TN 38054-5005

b. A copy of all invoices shall be sent to:

Fountain City Service Base Attn: Tammy Kime PO Box 397 431 North Shore Drive Fountain City, WI. 54629-0397
