PART 3 EXECUTION None. PART 4 SPECIAL PROVISIONS 4.01 Construction Sequence   A. The existing site is very problematic in the types of unsuitable fill placed over many years by previous owners.  The future use (municipal water works facility) will require the careful preparation of substrata to ensure future bearing capacities. The following narrative addresses these goals and provides a tractable sequence which will ensure the contractor is compensated for all earthwork with a minimum of unforeseen contingencies.  While the following treats the site as one, the contractor can divide the site into cells to break the work into manageable parts. While the sequencing of sub-cells may be adjusted (upon engineers approval), the sequencing for each cell particularly for quantifying must remain substantially as identified herein. 4.02 Clearing & SCALPING A. Clearing and scalping will completely remove all vegetative and woody material (including stumps) from the site as indicated in the construction documents. B. Existing north & west berm- remove all vegetative material from toe of slope to elevation of 751 (approximately 18 ft up-slope) C. Existing east berm- remove all vegetative material from the entire berm (both sides) D. All interior area - remove all vegetation, brush, and trees E. All clearing material to be removed from site at contractor’s expense. All scalped material will be mixed with Bio-Solids from the Wastewater Plant and reused as top soil on site. F. Salvage and stockpile existing aggregate drive to the City’s salt barn within area of operations. 4.03 Survey prior to excavation A. When clearing and grubbing is complete the contractor’s surveyor shall perform topographic survey of existing ground for basis of all pay quantity computations. Data to include cross section stationing shall be submitted and approved by engineer’s representative prior to any further excavation on site. 4.04 Site drainage A. Partial placement of outfall piping structure and temporary inlet installation for site drainage. B. Due to existing fill pile, the outfall pipe shall be placed from the existing Blue Woods Creek to the projects property line.  A temporary pipe and inlet shall be placed to the approximate ditch alignment at the contractor’s discretion. This shall also entail any temporary trenching to assist in site drainage. 4.05 Ramp installation A. Excavate and place geogrid for ramp to cross old pond substrata for access to excavate the site. B. This work while covered within normal bid items will necessitate coordination of cut and fill quantities as it will not lend itself to normal work flow for quantifying. 4.06 Excavation and stockpiling A. This can be sub-sequenced by the contractor in his operational proposal. The site can be divided into cells. The contractor can combine fill operations within cells. It is imperative that prior to working in any cell and particularly between step items, the contractor’s surveyor must submit calculations for quantities for agreement on pay items as completed.  B. Of particular note during this phase is that close coordination must be maintained with the owner’s geotech representative. All soils must be evaluated as encountered to determine suitability of soils. The main categories expected to be determined under the owner’s (geotech’s) supervision are: 1. Suitable soils to be used as Selected Fill in areas under buildings, pabvement, piping and adjacent to structures. 2. Unsuitable soils to be used as Fill Material in perimeter berms or other designated areas. Unsuitable soils are expected to be primarily the lime sediment. Notes: No swell or shrinkage factors will be applied for pay quantities. All side slopes were designed as 3:1 (except a small amount along the north side at toe of berm which was expected to hold 2:1 slope). If contractor cuts greater side slopes it will be at his expense. C. The cross sections identify several areas for overexcavation. Due to the subsoil conditions (area of old pond/lagoon) there will be several areas excavated to accommodate geogrid and engineered fill under pavements and yard piping areas. D. Sand layers will be encountered in some of the overexcavated holes. It is anticipated that these will generally drain well however dewatering shall be included in the bid items as a contingency. E. At conclusion of a given cells cut operation, contractor’s surveyor shall submit calculations to engineers representative for acceptance prior to any fill operations. 4.07 Placement of geogrid A. The “Geogrid” plan shows the general intent given preliminary soil condition investigations. A general area was chosen for questionable soil bearing capacities, which encompassed most of yard piping and paved surfaces.  Upon full excavation and owner’s geotech evaluation the areas deemed unsuitable shall be overlaid with geogrid along with the No. 2 and No. 53 aggregate layers. B. The pattern shown also excludes the area around the proposed structures (11.5 ft) to allow for placement of a full width geogrid (with 18inch overlap) during backfill in next phase.  C. Note: All fill above geogrid at building footprints are designed/calculated for pay at 1.5:1 slope. D. Edge of geogrid shall be left exposed adjacent to holes left for structure construction. E. Prior to aggregate placement contractor’s surveyor shall submit calculations for pay quantities and field stake building footprints to ensure no geogrid is located under future piling sites. F. All geogrid to be placed at a uniform elevation of 738.5 except as noted in plans. 4.08 Fill and final grading A. Balance of fill operations are brought as nearly as possible to finish grades. B. Access ramp shall remain but contractor shall ensure that surface runoff (storm) water will find designed drain, not into our hole via the ramp. C. Complete outfall structure, perimeter drain, and detention pond. D. Replace temporary aggregate drive to the City’s salt barn. E. Areas for grass plantings shall include 6 inches of engineered topsoil placement. F. Placement of silt fencing, temporary seeding and erosion control devices. G. A stockpile of “engineered fill” shall remain on site. This pile shall be surveyed and submitted for final adjustment of pay quantities. No quantities will be based on “truck load counts”. 4.09 removal of excess materials A. Excess soils can be disposed of on property recently acquired by the City of Carmel at the southern portion of Northern Beech located south of 116th St. and west of the White River. This site is only for the disposal of excess soils, vegetation from clearing operations must be disposed of at a landfill or other locations provided by the Contractor. 4.10 DRIVE TO SALT BARN A. Access to the Salt Storage Barn must be provided for City Personnel after November 16, 2009. 4.11 MINING OPERATIONS A. Martin Marietta continues to mine the rock underneath this site. Blasting operations will continue to be performed for the duration of this project. Blasting usually occurs once per day and may be performed under this site or in areas adjacent to this site. Any work that may be sensitive to Martin Marietta’s blasting operations must be scheduled in advance with Martin Marietta. 4.12 EXISTING SEDIMENTATION LAGOONS A. A sizeable portion of this site was previously mined for sand and gravel. The resulting depressions (lagoons) were subsequently filled in with washings from the sand and gravel operations. After the depressions were filled, the site was used for disposal of unsuitable gravel and other debris then more recently the site has been used for washing out concrete trucks. B.
