1' New Pryor Reclamation Project Cooperative Agreement Amendment Number 1 OSM-51 Narrative BUDGET BREAKDOWN Final reclamation was completed and accepted by the Mined Land Reclamation . Division on March 18, 1992. The final cost breakdown for this project ie outlined as follows: 561,900 initial Bid/Purchase Order Amount. 513,000 Change Order Number 1 51,300 Change order Number 2 51033 Anticipated seed cost $345 Unanticipated seed cost 53,000 Anticipated personnel cost 52,682 Unanticipated additional personnel cost JUSTIFICATION Change Order ~1 was initiated because the coal spoil volume was underestimated in the bid document due to unanticipated subsurface conditions. Upon excavation of the coal spoil, a previously unknown coal spoil filled ewale underneath the pile was encountered requiring the removal and placement of an additional 20,000 cubic yards. Also, additional equipment rental was required to spread out and bury coal waste at the northeast corner of the project. This work was unforeseen and therefore, not described in the bid document. Change Order ~2 was initiated because the placement of the coal spoil, final grading and topsoil was completed in July which was too late in the season to successfully fertilize, seed and mulch the site. A total of 9 erosion control berms were constructed on the contour to control erosion and avoid off site damage. The need for these structures was not anticipated in the original bid documentation. Also, an 8 inch by 50 foot deep abandoned drill hole was found on the project site. This hole was hand backfilled from bottom to top. This drill hole represented a significant hazard to the general public as it was located near some foundation ruins. It was large enough for a small child to fall into. It was anticipated that 17 acres would be disturbed during the course of this project. Actual measurement of disturbance revegetated totaled 22 acres. This increased the cost of the seed due to increased amounts necessary to do the work. The contractor seeded the entire disturbance for the original agreed price. The above changes due to unavoidable, unforeseen and hazardous conditions increased the project engineering and management costs as outlined. There was a significant increase in office and field presence requirements to insure that the work was completed according to the approved plan and within budget to the extent possible. -
