Push the backfill material carefully to the granular material and do not permit free fall of the material until at least 2 feet of cover are provided over the tope of the pipe. Under no circumstances allow sharp,heavy pieces of material to drop directly onto the pipe or the tamped material around the pipe. D. Final Earth Backfill: I. Earth backfill will, generally, be limited to use in present and future unsurfaced areas where.subsequent settlement will-not-cause_a..problem. 2. Compacted earth backfill will be required for the full depth of the trench to 12 inches above the top of the-pipe crown. Place backfill and fill materials in layers not more than 8 inches in loose depth for material compacted by heavy compaction equipment, and not more than 4 inches in loose depth for material compacted by hand-operated tampers. 3. Compact backfill material to 80 percent of maximum dry density according to ASTM D 698 or to a density equivalent to the density of the immediate adjoining soil. 4. Backfill material shall be.placed and compacted only when its moisture content is within .` 2.0 percent of optimum moisture content. 5. Under structures,compact the top 12 inches below subgrade and each layer of backfill or fill material at 95 percent maximum dry density. 6. No backfill shall be placed over or around any structure until the concrete mortar therein �l .has attained a minimum strength 2000 psi and can sufficiently support the loads imposed J by the backfill without damage. 7. The Contractor shall use utmost care to avoid any wedging action between the side of the excavation and the structure that would cause any movement of the structure. Any damage caused by premature backfill or by the use of equipment on or near a structure will be the responsibility of the Contractor. 8: Backfill shall be placed and compacted on all sides of the structure simultaneously, and :. operations shall be so conducted that the backfill is always at approximately the same elevation on all sides of the structure. 9. No excavated rock larger than two (2) inches maximum dimension shall be placed within 1 one (1) foot of the exterior surface of any structure. E. Granular Backfill: 1. Granular backfill will be required in present paved roadways, graveled roadways, gravel surfaced areas, future pavement areas, and in areas where pipes lie above or cross other pipelines as shown on the Drawings. Subsequent settlement must be held to a minimum in these areas. Granular backfill will also be required under manhole base sections. 2. Granular backfill will be required in all trenches.excavated under or within five (5) feet of pavements, driveways, sidewalks, structures, or as directed by the Engineer. 3. Place material in lifts not to exceed 8-inch loose thickness and compact each lift to 95 percent of maximum dry density at optimum moisture content as determined by ASTM D 698. Compact the top six inches of backfill in street right-of-way to 95 percent maximum dry density according to ASTM D 698. Compact the top six inches of backfill under walkways to 95 percent maximum dry density according to ASTM D 698. F. Water Settling of Trench Backfill: Water settling of trench backfill will not be considered an acceptable compaction procedure, and will not be permitted unless specifically approved by the Engineer.

No vibration or compaction is required. ' 2. The ends of backfill-placements shall be bulk headed with earth stanks or other means suitable to keep backfill material in its intended place. 3. CLSM may be placed to the subgrade_ elevation of the pavement and the pavement ' replaced within 24 hours of placing the CLSM. I. Cold Weather Placing of CLSM: Protect CLSM work from physical damage or reduced , strength, which could be caused by frost,freezing actions,or low temperatures. 1. When air temperature has fallen to or is expected to fall below 40 degrees F (4 degrees C), uniformly heat eater and aggregates as necessary before mixing to obtain a CLSM mixture temperature conforming to Table 1.4.1 of ACI306 Report and maintain protection for minimum times as noted in Table 1.4.2 of ACI 306 Report. The rate of cooling should be gradual and should not exceed 40 degrees F per 24-hour following the cessation of heat application. 2. Do not use frozen materials or materials containing ice or snow. Do not place CLSM on frozen subgrade or on subgrade containing frozen materials .' 3.10 FIELD QUALITY CONTROL A. Quality Control Testing During Construction: Contractor shall retain a testing service to inspect ' pipe subgrade, bedding, and pipe backfill and obtain approval of Engineer before further construction work is performed. Allow field density tests to be performed in accordance with ' ASTM D1556 (sand cone method), ASTM D2167 (rubber balloon method), or ASTM D2922 and D3017 (nuclear method)as applicable. 1. Slumps and compressive strengths of CLSM shall be tested as requested by the Engineer ' and not to exceed one set of tests per 100 cubic yards. B. Have at least two field density tests taken at locations and elevations as directed, but in no case ' less than two tests per 500 lineal feet of trench backfill under structures, pavements, or sidewalks, unless otherwise approved by the Engineer. When backfrlling in present and future unsurfaced areas, a minimum of two field density tests are required per 100 lineal feet of trench. C. If,based on testing service reports and inspection, subgrade or fills, which have been placed,are below the specified density,provide additional compaction and testing at no additional expense. ' D. Results of density tests,which may be selected, will be considered satisfactory when they are in each instance equal to or greater than specified density.

WAGE ODER: 14 There is a 36"_Steel Aerial Pipe Crossing that needs to be replaced. It is located between the Railway Bridge and the Missouri River across Wears Creek. The steel pipe has a lead paint primer. Safety precautions should be observed. There is no excess storage or method to temporarily reroute flow, so the system will have to remain in operation during the repair or bypass pumping will have to b_e provided. Three alternatives are being bid: 1. Replacement of the pipe with long-span ductile iron. The bypass pumping requirements of Section 2790 apply. For cutting pipe, etc., Section 1732 applies. 2, Place Stainless Steel encasement on exterior of pipe in accordance with Drawings S-03 and S- 04.

The fourth alternative is replacement of the two manholes on either side of the creek. This would require bypass pumping per Section 2790. J Recently, the proposed pedestrian/bike trail has created interest in relocating the aerial crossing to the � north. This alternative will be added to the bid by addendum. This will also require the bid date be moved. It was the consensus that July 3 would provide enough time to add Alternative 5.

Local rep said they are much deeper than the sewer. If excavation occurs on either side of the creek, they can be contacted to indicate location and depths. There is OH electric that should be considered for boom and lifts. Corps of Engineers approval has been obtained for Alternatives 1-4. Further approval will have to be obtained for Alternative 5. Alternative 5 is based on known conditions to obtain a bid price. Design will be reviewed by geotechnical and structural engineers prior to construction. Any major changes would be adjusted by change order. QUESTION/ANSWER: (Received at the pre-bid meeting) • QUESTION: Will the manholes be replaced with standard 4' manholes?
