Trench Stabilization: No claim for extras, or additional payment will be considered for cost incurred in the stabilization of trench bottoms which are rendered soft or unstable as a result of construction methods, such as improper or inadequate sheeting, dewatering or other causes. In no event shall pipe be installed when such conditions exist and the Contractor shall correct such conditions so as to provide proper bedding or foundations for the proposed installations at no additional cost to the Owner. B. Removal of Water: 7-15

15 1. It is a basic requirement of these specifications that excavations shall be free from water before pipe or structures are installed. 2. The Contractor shall provide all necessary pumps, underdrains, well-point systems, and other means for removing water from trenches and other parts of the work. The Contractor shall continue dewatering operations until the backfill has progressed to a sufficient depth over the pipe to prevent flotation or movement of the pipe in the trench and so that it is above the natural water table. 3. Water from the trenches and excavation shall be disposed of in such a manner as will not cause injury to public health, to public or private property, to the work completed or in progress, to the surface of the streets, or cause any interference with the use of the same by the public. The Contractor shall submit his proposed methods of handling trench water and locations at which the water will be disposed of to the Engineer for approval and shall receive approval before starting the excavation. 4. Pumps and engines for dewatering systems shall be operated with mufflers and at a minimum noise level suitable to a residential area. The Contractor shall be responsible for any nuisance created due to the disposal of water from his drainage system. C. Pipe Bedding: 1. As described above, all pipe trenches shall be excavated to a level 8 inches below the outside bottom of the proposed pipe barrel. The resulting excavation shall be backfilled with approved pipe bedding material, up to the level of the lower one-third of the proposed pipe barrel. This backfill shall be tamped and compacted to provide a proper bedding for the pipe and shall then be shaped to receive the pipe. Bedding shall be provided under the branch of all fittings to furnish adequate support and bearing under the fitting. Bedding material for piping shall be good suitable soil material, pea rock, FDOT stone, or similar materials as approved by the Engineer. All pipe shall be installed in a dry trench. 2. Any excavation below the levels required for installation of the pipe bedding shall be backfilled with approved bedding material provided by the Contractor, tamped, compacted and shaped to provide proper support for the proposed pipe, at no additional cost to the Owner. D. Backfills and Compaction 1. Backfilling of trenches shall not be allowed until the work has been approved by the Owner, pressure tested if required, and the Engineer indicates that backfilling may proceed. Any work which is covered or concealed without the knowledge and consent of the Owner shall be uncovered or exposed for 7-16

16 inspection at no cost to the Owner. Partial backfill may be made to restrain the pipe during pressure testing. 2. Backfill material shall be suitable material as described herein. Backfill material placed within 1 foot of piping and appurtenances shall not contain any stones or rocks larger than 2 inches in diameter (1 inch for PVC pipe) and no stones or rocks larger than 6 inches in diameter will be permitted in any backfill. 3. If a sufficient quantity of suitable backfill material is not available from the trench or other excavations within the site of the work, the Contractor shall provide additional material suitable for this purpose. The additional material shall be installed as specified herein. 4. Suitable backfill material containing no stones or rocks larger than 2 inches shall be placed in 6 inch layers and thoroughly tamped to a depth of 12 inches over the top of the pipe. Particular attention and care shall be exercised in obtaining thorough support for the branch of all service connection fittings and compaction of the fill under the haunches of the pipe. Care shall be taken to preserve the alignment and gradient of the installed pipe. 5. After the backfill has been placed to a level 12 inches over the waterline or force main pipe, the remainder of the backfill shall be placed in layers, not to exceed 12 inches, and compacted with mechanical vibrators or other suitable equipment, to obtain a minimum density equivalent to 95 percent of the Maximum Modified Proctor Density in accordance with ASTM D After selected backfill has been placed to a depth of 12 inches over the storm drainage and sanitary sewer pipe, backfilling shall proceed to a depth of 30 inches over the pipe by placing the backfill material in 9 inch layers and thoroughly compacting it with mechanical vibrators. Backfill in this portion of the work shall be compacted to a minimum density equivalent to 95 percent of the Maximum Modified Proctor Density in accordance with ASTM D After the backfill has been placed to a level 30 inches over the storm drainage and sanitary sewer pipe, the remainder of the backfill shall be placed in layers, not to exceed 12 inches, and compacted with mechanical vibrators or other suitable equipment to obtain a minimum density equivalent to 95 percent of the Maximum Modified Proctor Density in accordance with ASTM D For storm drainage and sanitary sewer pipe in unpaved areas outside the right-of-way, the backfill shall be placed to a level 36 inches above the crown of the pipe by placing the backfill material in 9 inch layers and compacted to a minimum density equivalent to 95 percent of the Maximum Modified Proctor Density in accordance with ASTM D

17 9. No more than 800 feet of trench with pipe in place shall be partially backfilled at any time. E. Additional Excavation and Backfill: F. Grading 1. Where unsuitable material, such as organic soils, roots, mulch, other vegetable matter, or other material which, in the opinion of the Engineer, will result in unsatisfactory foundation conditions, is encountered below the level of the proposed pipe bedding material, it shall be wholly or partially removed as directed by the Engineer and disposed of off-site at the Contractor's expense. Sheeting shall be installed, if necessary, to maintain pipe trenches within the specified limits. The resulting excavation shall be backfilled with suitable backfill material, placed in 6 inch layers, tamped and compacted up to the level of the bottom of the proposed pipe bedding material. Sufficient compaction of this material shall be performed to protect the proposed pipe against settlement. Construction shall then proceed in accordance with the provisions as specified above. 2. Additional excavation shall be performed only when ordered by the Owner. Where organic or other unsuitable material is encountered in the excavation, the Contractor shall bring the condition to the attention of the Engineer and obtain his determination as to whether or not the material will require removal, prior to preparing the pipe bedding. 1. Grading shall be performed over the total construction area, as indicated on the Drawings. This work shall include all cutting and filling necessary in order to comply with the elevations shown on the Drawings. 2.
