1.2.17 Measurement Procedures

1.2.17.1 Concrete Removal

NOTE: 25 mm 1 inch tolerance is suitable for concrete removal over150 mm 6 inches deep. For thinner repairs, a tighter tolerance would be more appropriate. The methods of removal should also be considered. The relative costs of achieving closer tolerance should be weighed against the anticipated benefits.

Remove concrete to the lines of removal indicated on the contract drawings. A tolerance of plus or minus [25 mm 1 inch] [13 mm 1/2 inch] will be allowed about the lines indicated [except in the thin wall areas where no removal beyond that indicated will be permitted]. Concrete removals that vary by more than the indicated tolerance will be acceptable, unless evidence indicates that deteriorated concrete is still present or the variation in tolerance results in a violation of the requirements for material placement, in which case removal shall continue to the lines indicated. Additional concrete removal beyond the allowable tolerance will be acceptable when deteriorated concrete is found as determined in accordance with paragraph Determination of Removal Limits, and the limits of such removal are set and approved by the Contracting Officer.

Unauthorized concrete removals in excess of 25 mm 1 inch beyond the lines shown will not be acceptable, and repair of such excess area shall be performed by the Contractor to the satisfaction of the Contracting Officer and at no additional cost to the Government.

1.2.17.2 Measurement of Vertical Concrete Removal

Determine the volume of vertical concrete removal from cross sections made prior to and after removal. Make cross sections from surveyed measurements [on a 1.5 by 1.5 meter 5 by 5 foot grid system] [at a minimum of 20 points], unless otherwise specified by the Contracting Officer. Take initial survey of the existing surface prior to removal, and take final surveys on the same control stations. Calculate volumes by the average-end-area method using the cross sections surveyed, unless otherwise specified. For areas of vertical concrete removal which are not readily accessible for survey, determine the volume of concrete from the neat lines of concrete removal as shown on the contract drawings, with the approval of the Contracting Officer,. Do not include any volume of concrete removal made beyond the allowable tolerances specified.

1.2.17.3 Measurement of Horizontal Concrete Removal

Determine volumes of horizontal concrete removal from cross sections made prior to and after removal. Make cross sections from surveyed measurements [on a 3 by 3 meter 10 by 10 foot grid system] [at a minimum of 20 points], unless otherwise specified by the Contracting Officer. Take initial survey

SECTION 03 01 32 Page 16 of the existing surface prior to removal, and take final cross sections at the same control stations. Calculate volumes by the average-end-area method using the cross sections surveyed, unless otherwise specified. Do not include any volume of concrete removal made beyond the allowable tolerances specified.

1.2.17.4 Measurements of Concrete

For areas that are readily accessible by a survey crew, determine volumes by cross sections of the areas prior to and after concrete placement. Take the initial and final cross sections at the same control stations used for concrete removal where possible. Calculate volumes by the average-end-area method using the cross sections surveyed, unless otherwise specified. For areas of concrete placement which are not readily accessible for survey, determine the volume of concrete from the neat lines of concrete placement as shown on the contract drawings. Do not include any volume of concrete placed to compensate for removal made beyond the allowable tolerances specified.

1.5 SYSTEM DESCRIPTION

1.5.1 Design Requirements

NOTE: If higher earlier strength is needed for repairs, revise this paragraph to provide appropriate criteria. The mixture design should maximize aggregate size and minimize the water-cementitious material ratio to reduce shrinkage. Material properties should be coordinated with EM 1110-2-2002 Evaluation and Repair of Concrete Structures. Where other guide specifications are included in the project specification, ensure that appropriate parameters are inserted in the applicable specification.

Consideration should be given to including and alternative age other than 28 days such as 90 days when pozzolan is used to provide more cost effective use of materials. If flowability of the grout is important, use ASTM C1017/C1017M for admixture and specify where it is to be used; otherwise use ASTM C494/C494M.

Submit manufacturer's literature from suppliers that demonstrates compliance with applicable specifications for the above materials. For proportioned materials, submit three copies of the proposed mix design prior to placement. The mix design shall indicate the weight of each ingredient of the mixture. No concrete shall be placed prior to approval of the proposed mix design. No deviation from the approved job-mix formula will be permitted without prior approval.
