DEFINITIONS Goals: A flexible numerically expressed objective which contractors are required to make "good-faith efforts." The key to the requirement is to make documented efforts.

Rather, the goal-setting process in affirmative action planning is used to target and measure the effectiveness of affirmative action efforts to eradicate and prevent discrimination. Quota: A flat numerical requirement that the contractor is required to meet in order to obtain the benefit or be in compliance. The numerical goal component of affirmative action programs is not designed to be, nor may it properly or lawfully be interpreted as, permitting unlawful preferential treatment and quotas with respect to persons of any race, color, religion, sex, or national origin. The regulations at 41 CFR 60-2.12(a), 60-2.15 and 60-2.30, specifically prohibit discrimination and the use of goals as quotas.

When an embankment is placed on or against an existing slope that is steeper than 3:1 and is more than 10 feet high, cut the slope into steps as the construction of the new embankment progresses. The steps should ensure that all sod or other potential sliding surfaces are removed. Cut each step or series of steps to approximate horizontal planes which have vertical slope dimensions of at least 3 feet. C. Depositing Embankment Material: 1. Except for rock fills and granular blankets, deposit embankment material in horizontal layers no greater than 8 inches in loose thickness. Do not incorporate vegetative materials in embankments. If some otherwise suitable soil contains small amounts of vegetative materials, such soils may be deposited outside of the shoulder line, within the outer 3 feet of the embankment. 2. When the width at the attained height is 30 feet or more, divide the area upon which the layer is to be placed into separate and distinct dump areas, having widths of at least 15 feet. If hauling equipment is operated within a dump area, cover the area with at least one passage of a tandem-axle disk, or two passages with a single-axle disk, prior to compaction. 3. Keep hauling equipment off dump areas of embankments 36 feet or more in width during compaction operations. Within 36 feet of a bridge or other limiting structure, or where the width of the embankment is less than 36 feet at the attained height, empty hauling units may travel on the dump area during compaction operations, as necessary to pass loaded hauling units. If the design width of the embankment is less than 30 feet at the attained height, hauling units will be allowed to travel through areas where compaction operations are in progress. When any hauling equipment is allowed to pass through compaction operations, do not require water, disking, and compacting equipment to deviate from their intended paths. 4. Deposit the material over the dump area as a separate and distinct operation. If the material, as deposited, contains an average of more than one lump per square yard, large enough to have at least one dimension greater than 12 inches, cover the area by at least one passage of a tandem-axle disk, or two passages of a single-axle disk. Use a disk that is designed and operated to cut and stir to the full depth of the layer. 5. After depositing and disking, if required, smooth the material to a uniform depth with a 2010—pg12 Standard Specifications Division 2—Earthwork Section 2010- Earthwork,Subgrade, and Subbase suitable motor patrol, bulldozer, or self-propelled sheepsfoot-type roller with a blade attachment. In addition to the initial smoothing operation, continue this smoothing and leveling of the lift during compaction, as necessary to provide a surface area free from ruts and other objectionable irregularities. Use the self-propelled sheepsfoot-type roller(meeting the requirements of Ic;wa DOT Article 2001.05) under the following conditions: a. Leveling must be done according to the prescribed rolling pattern. b. Compaction should be the primary function of the unit. c. Prevent spinning of the power drums. d. When, in the opinion of the Engineer, the unit cannot satisfactorily accomplish both leveling and rolling, use a separate dozer or motor patrol for the leveling 13peration prior to initiation of compaction. e. For embankments constructed primarily of sand or other granular material, the Contractor may substitute a pneumatic-tired roller meeting the requirements of Iowa — DOT Article 2001.05. 6. Keep the outer portion of an embankment lower than its center, and wherever construction will be suspended for a period during which rain is likely to occur, roughen the surface to prevent erosion. This can be done by tracking, disking, or scarifying. Stones 6 inches and smaller in diameter may be placed in embankments, but distributed to avoid pockets. No stones larger than 3 inches may be placed within 1 foot of the finished subgrade elevation. D. Compaction with Moisture and Density Control: Compact with moisture and density control, unless Type A compaction is specified in the contract documents. See E ection 2010, 3.09 for moisture and density requirements. E. Type A Compaction:When Type A compaction is specified in the contract documents, compact as follows: 1. After the surface layer has been smoothed, and before material for the next ayer is deposited on it, compact the layer with at least one passage of the sheepsfoot-type roller per inch of loose thickness of the layer, until the roller is supported entirely on its feet. The roller will be considered to be supported entirely on its feet when the tamping feet penetrate no more than 3 inches into an 8 inch lift or layer being compacted. 2. Determine if moisture content of the material is excessive or suitable for satisfactory compaction. a. Start rolling operations immediately after the smoothing operation, or dewy them, and instead aerate the material in preparation for rolling. b. Perform aeration and compaction operations without unnecessary delay c. Rolling operations made prior to any aeration operations for a lift will not be counted as any of the required coverages. 3. If the material is dry to the extent that it will not likely be satisfactorily compacted by rolling, moisten the material. a. The Engineer may order the material to be moistened uniformly before it is compacted. b. The Engineer may authorize the use of water in the final finishing of the roadbed. c. Delays from the ordering of moistening or drying will be at the Contractor's expense. 4. The Contractor may substitute compaction with moisture and density control for Type A Compaction, providing all testing as required, at the Contractor's expense. 3.05 USE OF UNSUITABLE SOILS Unsuitable soils are not allowed in the right-of-way, unless otherwise specified in the contract documents or allowed by the Engineer. 2010—pg 13 Standard Specifications Division 2—Earthwork Section 2010- Earthwork,Subgrade, and Subbase 3.06 SUBGRADE PREPARATION Shape and consolidate subgrade in preparation for the placement of pavement.

Use light mechanical tampers to achieve the — required compaction in a strip 3 feet wide adjacent to the backside of the wall; compaction density testing will not be required within 3 feet of the back of the wall. 3. Tieback Reinforcement Installation: Install tieback reinforcement according to the manufacturer's requirements. C. Limestone Retaining Wall: 1. Place limestone slabs. Ensure adjacent slabs are in full contact without gaps. 2. Stagger vertical joints so no joint is located closer than 2 feet to a joint in the course below it. 3. After each course is laid, place backfill material behind the wall and compact with hand tools to a density equal to or greater than the existing soil behind the wall. D. Landscape Timbers: 1. Lay first course of timbers horizontally, ensuring timbers are level. Set back each succeeding course 1/2 inch. 2. Secure each course to the course below it using spikes placed 2 feet from each joint and spaced at no more than 4 feet. Drill pilot holes in timbers to facilitate installation of —I spikes. 3. Stagger vertical joints so no joint is located closer than 2 feet to a joint in the course below it. 4. Install tiebacks with length equal to the wall height, perpendicular to the wall face, spaced at 8 feet. Stagger location of tieback on each course. Do not install tiebacks in bottom three courses or upper two courses of timbers. Ensure the end of the tieback is flush with the front of the retaining wall. Attach tieback to course below it using a spike. 5. After each course is laid, place backfill material behind the wall and compact with hand tools to a density equal to or greater than the existing soil behind the wall. END OF SECTION 6 10/18/2011
