SECTION 4 DIVISION II EXCAVATION AND CLEANUP 4.1 GENERAL: Certain notes appear on the plans that modify or clarify the Detailed Specifications. These notes where in conflict with the Detailed Specifications or Modification to Detailed Specifica- tions shall govern. 4.2 PARAGRAPH 20-2.08A - BRACED AND SHEETED TRENCHES - GENERAL: The Contractor's attention is directed specifically to the requirement that tight sheeting is required along State Highways under certain conditions. All sheeting used shall be pulled. Select granular backfill shall be placed before sheeting is pulled where required. 4.3 PARAGRAPH 20-2.19 - UNDERGROUND CONDUIT CONSTRUCTED IN TUNNEL: The following paragraphs shall be added to the applicable sub-paragraph. Where they are in conflict they shall govern. STEEL CASING PIPE IN PLACE: Where shown on the plans the Contractor shall construct casing pipe below ground surfaces by augering and jacking as herein specified. DS-3 r • Casing pipe jacked in place shall be welded steel pipe, in accordance with ASTM Designation A 139 Grade B and a minimum yield of 35,000 psi. The casing pipe shall have a minimum wall thickness as shown on the plans. Each jacking shaft shall be completely sheeted to provide proper support for the bank and adequate support for reaction blocks. The shaft shall be constructed long enough to provide room for jacking head, frame, reaction blocks and a minimum of 15 feet of casing pipe. The width shall be sufficient to allow ample working room. The backstops or reaction blocks shall be placed absolutely perpendicular in all directions to the axis of the pipe and the guides carefully installed to the proper line and grade. Jacking pressure must be applied by a pushing frame at right angles to the line to avoid forcing the casing pipe out of alignment. The first section of casing pipe shall be equipped with a steel cutting shield placed over the upper one-third of its circumference and securely fastened to the pipe. The casing pipe shall be installed using equipment that encases the excavated hole as earth is removed. Excavation and/or boring without the concurrent installation of the casing pipe will not be permitted. All joints in the casing pipe shall be continuously welded. The jacking operation shall be continuous insofar as possible to prevent seizure of the casing pipe. The Contractor shall excavate and dispose of material of any nature required to carry out the work. Shaft excavation shall be in accordance with applicable paragraphs of the Specifications. All 4!) excavated material from shaft and casing pipe placement shall be promptly removed and disposed of. Upon completion of casing pipe placement and after the sanitary sewer carrier pipe is installed within the casing the shaft shall be filled with selected granular backfill . The cost of said backfill shall be considered incidental to the cost of the contract and no additional compensation will be allowed. After the casing pipe is in place the Contractor shall install the sanitary sewer carrier pipe, of the size and material specified, within the casing pipe and to the line and grade established by the Engineer. When treading of the carrier pipe is complete and approved by the Engineer, the Contractor shall fill the voids between the inner wall-of the casing pipe and the outer wall of the carrier pipe with sand. The ends of the casing pipe shall then be sealed by placement of a minimum of ten (10) inches of concrete, or in some other manner approved by the Engineer. The Contractor shall furnish, install and maintain all facilities for collecting, conveying, and displacing of ground and/or surface waters within or around the shaft excavation until the completion of the work. The Contractor shall have on hand at all times sufficient machinery for all emergencies that are likely to arise on work of this character and such machinery shall be kept in good working order. The pumping and power supply to the pumps, etc. , shall be under the direct charge of competent mechanics. DS-4 I • 4.4 PARAGRAPH 20-2.21 BACKFILL: The plans show where selected granular fill is required. Selected granular fill shall be type A, B, C or D as specified in the Specifications or as determined during construction. Where selected granular fill is not required excavated material may be used for backfill if suitable. All backfill not requiring mechanical tamping shall be jetted. The Contractor shall make arrangements for the purchase of water for jetting from the City of Elgin and pay all costs. 4.5 PARAGRAPH 21-2.01 TEMPORARY SURFACE OVER TRENCH: Temporary surfaces for driveways shall be provided as soon as the trench is backfilled. This work shall be incidental. SECTION 5 SANITARY SEWERS AND STORM DRAINS 5.1 GENERAL: Certain notes appear on the plans that modify or clarify the Detailed Specifications. These notes where in conflict with the Detailed Specifications or Modifications to Detailed Specifica- tions shall govern. 5.2 PARAGRAPH 31-1.02 PIPE LAYING: All pipe shall be laid utilizing a laser device for controlling line and grade. 5.3 PARAGRAPH 31-1.11 TESTING FOR ACCEPTANCE OF SANITARY SEWERS: Testing shall be by lamping and the air test method. If flexible thermoplastic pipe is used deflection testing is required. Prior to testing the Contractor shall thoroughly clean the pipe using a cleaning ball or other approved method. 5.4 SECTION 32 MANHOLES: Manholes shall be in accordance with the details attached to these Specifications. r l I I I I DS-5 I AI'PLCATION FOR PAYMENT NO. 1 t (OWN Contract for Dated OWNER'S Project No ENGINEER'S hoject No. For Wort oaaomololmd through the date of r" CIDW ACTOR.fad.l M Yaw.

For this investigation a total of five borings were drilled at the locations and to the depths indicated by your office. We are enclosing copies of the boring logs, summary of test results and location sketch. At the location of borings 1 thru 4, topsoil and topsoil mixed with silt is indicated in the upper soil layers. The underlying soils are found to be predominantly granular soils consisting of silt and fine sand mixed with lesser portions of clay and gravel. Occasional layers of predominantly clay soils are encountered at borings 1 and 2. The test results indicate that the upper portions of the underlying soils are found to be high in moisture content. Reduced moisture contents are indicated at the deeper elevations, except in the area of boring 3, where high moisture content is recorded in the brown-gray clay layer between 6.0 feet and 9.5 feet. No measurable ground water was encountered at the location of borings 1, 4 , and 5. At borings 2 and 3 high water level readings of 3.0 feet and 12.5 feet were recorded respectively. Further, at the location of boring 3, a saturated layer of sand is encountered between 4.0 feet and 6.0 feet. Meas- urable water seepage from this layer was not recorded. The enclosed boring logs indicate the elevation of the proposed sanitary sewer. As can be seen, sand and silt soils are generally encountered at this elevation. Excavations to this depth will remove confining pressures on the embankment soils. These soils are anticipated to become unstable when pressures are removed. Adequate protection should be provided in the work area against slope instability. Shallow excavations of less than 5.0 II Irk I ENGINEERING • TESTING • INSPECTION • OUALITY CONTROL r . • v i Everett Scheflow Engineers March 31, 1981 RE: Larkin Avenue Sanitary Sewer File No. 6447 Page 2 • feet may be sloped in order to prevent embankment failure. At the deeper 1 elevations it is anticipated that vertical cuts will be made requiring a steel box to protect the working area. In particular, those areas where saturated soil layers are encountered are anticipated to provide the great- est amount of instability at the earliest time. Were silt and fine sands are encountered at the bedding elevation and high moisture is present it is probable that these soils will become unstable. The result is a loosening or fluffing of these soils. If instability is observed, a bedding of 8.0 inches to 10.0 inches of crushed granular material should be provided to establish a stable working surface. The soils indicated at borings 4 and 5 are fine grain soils consisting of sand and silt. Little or no trace of cobbles and boulders was observed at the locations drilled. The augering or jacking operation under Larkin Avenue ` should encounter few or no obstructions. The 16.0 inch diameter steel casing already planned to protect the sanitary pipe is necessary to prevent cave-in in the augered shaft. 47)` After you have reviewed the enclosed information we would be pleased to dis- cuss any questions which you may have.
