NOTES Refer to separate specifications manual for additional project requirements. SCHEDULE Contractor shall complete grading of these facilities within 60 days of the notice to proceed. Landscaping must proceed as soon as possible after final grading but within specified time periods. SURV EY Benchmarks used to develop- the sitemap have been identified - on the plans. Information for these benchmarks will be provided by the Construction Manager. Otherwise contractor will provide any needed survey equipment, materials and personnel to insure the project is constructed to meet lines and grades as specified. SOIL MATERIALS It is anticipated that all suitable soil materials required to complete the project are present on site. Replacement of unsuitable materials will be paid on basis of conditions of Contract relative to changes in work. EXCAVATION Excavation consists of removal of material encountered to subgrade elevations indicated on cross sections and subsequent disposal of materials removed. Contact the Indianapolis Water Co. regarding the location of water lines in the vicinity. Avoid any damage. Contractor is responsible to repair damaged utilities to satisfaction of utility owner. Should uncharted piping or other utilities be encountered during excavation, consult utility owner immediately for directions. Perform excavation work in compliance with authorities having jurisdiction. Subgrade: The undisturbed earth or the compacted soil layer immediately below topsoil materials. Prior to excavation/grading mow existing vegetation throughout the work area to 3 inches or less in height, as needed. Remove vegetation in area of excavation. Avoid any vegetation disturbance in existing wetland. Install temporary silt fence along boundary of existing wetland as shown on plans and details. Excavate and separate the top 6" of soil from the rest of the soil excavated. (When backfilling, this separated topsoil will be replaced last). Then excavate subgrade to 6" below final grade, so that lines and grades meet specified grades after topsoil replacement. Unauthorized excavation consists of removal -of materials beyond indicated subgrade elevations on cross sections dimensions without specific direction of the Construction Manager. Unauthorized excavation, as well as remedial work directed by the Construction Manager shall be at Contractor's expense. Backfill and compact unauthorized excavations as specified for authorized excavations of same classification, unless otherwise directed by the Construction Manager. Additional Excavation: When excavation has reached required. subgrade elevations, notify the -----Construction-Manager,-who-will-make-aninspection--of-conditions.If-theConstruction-Manager-determines --- that subgrade elevations are unsuitable, continue excavation or backfill until subgrade elevations and drainage conditions are approved. The Contract Sum may be adjusted by an appropriate Contract Modification. Removal of unsuitable subgrade material and its replacement as directed (other than that specified) will be paid on basis of Conditions of the Contract relative to changes in work. GRADING r are s wtth n is rod n includ d sr r h fr Uniformly ode a t 1 mt of �n adjacent Iran ton areas. Smoot ntshed Y 9 9 9 g J surface by providing uniform levels or slopes between points where elevations are indicated or between such points and existing grades. Protection of Graded Areas: Protect newly graded areas from traffic and erosion. Keep free of trash and debris. Repair and reestablish grades in settled, eroded, and rutted areas to specified tolerances. Reconditioning Compacted Areas: Where completed compacted areas are disturbed by subsequent construction operations, flooding or adverse weather, scarify surface, reshape, and compact to required density prior to further construction. TOPSOIL AND FINAL GRADING Loosen subgrade to a minimum depth of 4 inches. Remove stones measuring over 1-1/2 inches in any dimension. Remove sticks, roots, rubbish, trash, and other extraneous matter to a depth of not less than 4 inches. Spread topsoil to 6" minimum depth. Final grade after topsoil placement required to meet lines, grades, and elevations shown, after light rolling and natural settlement. Pack the seedbed firmly with a roller or log sled. Remove ridges and fill depressions, as required to meet finish grades. WATER LEVEL CONTROL STRUCTURE PIPES AND APPURTENANCES Install water level control structure, pipes and appurtenances according to drawing. Use PVC riser pipe and elbow of the same size and quality of existing drain pipe or better. All joints must be water tight. Install Bar Guard as available from Agri -Drain Corporation (1-800-232-4742) or equivalent (approved by Construction Manager). 0 CLEANUP rn Remove all refuse from the site upon completion of construction. N INSPECTION AND ACCEPTANCE QWhen all construction work is completed contact the Construction Manager to make an inspection to determine acceptability. - -- - i 3 a) 0 c 0 LO w 0 LANDSCAPING The Construction Manager shall be notified, prior to beginning planting operations. Ship landscape materials with certificates of inspection required by governing authorities. Do not allow delivery of seed to the site more than one week prior to installation. Store in a cool dry location prior to installation. Provide fresh, clean, new -crop seed complying with tolerance for purity and germination established by Official Seed Analysts of North America. Provide seed mixture composed of grass and other species in the proportions specified. The following Wetland seed mix will be planted in the area of grading, as available from Heartland Restoration Services (219.489.8511).
