RE: Amendment Number 1 to PKA-15-750

Thank you for attending the pre-bid meeting on April 9, 2015. Please note the following changes to the Bid Document. A REVISED Bid Schedule is attached to this amendment. The Bid is due for this project on Monday, April 27, 2015 at 4:00PM. The bid opening will occur on Tuesday, 10:00AM on April 28, 2015.

1. The site access road and BLM road may need improvement, deadfall removal, brush clearing, grading, etc., to improve the access for delivery of materials and machinery to the site. This task will be billed by the hour under Task 11, Additional Excavator Time.

2. The following language has been added to Task 2, SHEAP: Fire Prevention:

CONTRACTOR must supply each work crew with two (2) five pound (5#) Class A fire extinguishers. Additionally, each crew member must be supplied with one (1) sharpened round nosed shovel. These must be immediately available to the crew members for use should an ignition occur.

3. A Dozer can be used for Task 4, Site Preparation. If a dozer is used to rip the site, the dozer must make three passes, each perpendicular to the previous pass. The final pass must be along contour to reduce erosion.

4. Removal of root balls from the project area has been added to Task 4. All root balls larger than 12" must be removed and stockpiled with the logs for use in final reclamation. An excavator with a thumb can be used to remove the logs and woody root materials.

5. An articulated haul truck is no longer required for Task 5. An All Wheel Drive haul truck IS required. An acceptable truck will have power assist to all wheels. Highway haul trucks will not be accepted. CONTRACTOR may also use a wheel loader to haul materials from the Engineer Pass Road to the site.

6. For bidding purposes, the stockpile location for the Lime and Compost will be the Hanna Mill Site, approximately 2.0 miles from the job site (3/4 of a mile past the turn off from Engineer Pass Road). DRMS will work with Hinsdale County locate a stockpile location closer to the split in the road.

7. The stockpile of pulverized limestone must be covered to protect it from blowing and getting wet.

8. Hydrated lime (Ca(OH)2) will not be accepted as a substitute for pulverized limestone.

9. A side dump truck will be accepted, however, the site for stockpiling the limestone may not accommodate a side dump. Belly dump trucks will NOT be permitted, due to the dry/fine-grained nature of the materials.

10. Compost must be Gunnison Gold or approved equivalent. An approved equivalent must meet the specifications of Class I Compost. See attached sheet for compost class descriptions.

11. Task 7 has been amended to require that Certified Weed Free Hay be delivered to the site in small two string bails, weighing 60-80lbs each. Large bails will not be accepted.

12. The CONTRACTOR will be required to apply lime and compost to the site, starting in the lowest portion of the western lobe, and working upslope, and then progressing to the eastern lobe. Lime will be placed at a rate of 135 cubic yards per acre. Lime will be applied to the site to an approximate depth of one inch (1"), and covered by compost within two hours, to avoid blowing of limestone materials. Compost application rate will be 200 cubic yards per acre, which equates to approximately1.5 inches across the site.

13. Effective mixing of the limestone and compost will be tested by the PROJECT MANAGER using a fizz reaction with 10% HCL acid, prior to moving to the next portion of the project area. Based past experience, the ALLU mixing bucket is approximately 10x more efficient at completely mixing soil amendments. The CONTRACTOR may propose an alternative mixing method, however, if inefficient mixing occurs (based on fizz reaction test) due to the alternative mixing method, the CONTRACTOR will re-mix materials at no cost to DRMS. The ALLU bucket or the proposed alternative MUST be listed on the List of Equipment Offered.

14. Limestone and compost Material must be mixed on the same day they are spread. The CONTRACTOR must plan accordingly, so that materials are not spread faster than the ALLU or mixing alternative can mix the materials.

15. An additional 10 hours of additional excavator time has been added to the project.

16. Dozer Time has been added to the project as Bid Item 13:

Task 13: ADDITIONAL BULLDOZER TIME This item includes additional machine time for a D4 Bulldozer (or larger) with operator to be used for road improvements, staging area grading, etc., as directed by PROJECT MANAGER.

Equipment time will be accounted for in accordance with Equipment Rental Specifications 19 in the General Bid Specifications, 2009. Equipment time will start as directed by PROJECT MANAGER once the excavator is mobilized to the site. The hours of additional bulldozer time in Bid Item 13 are NOT GUARANTEED

Measurement and Payment Payment for this task will be reflected under Item 13 of the Bid Schedule as an hourly rate for a bulldozer and operator. Bid hourly rate shall reflect the CONTRACTORS estimate for equipment and personnel cost per hour to complete the task. Measurement will be actual hours required to complete work as directed and approved by the PROJECT MANAGER. The hours of additional bulldozer in Bid Item 13 are NOT GUARANTEED.

17. Davis Bacon wages are NOT required for this Project.

All terms and conditions, other than as changed in this amendment, remain the same.

Receipt and acceptance of this amendment must be acknowledged on the bid form.

Return by April 27, 2015 at 4:00 P.M. to: Receipt of Addenda Nos._______________ is hereby acknowledged Submit Electronically:
