Questions and Clarifications:

1. Base Bid Item No. 3 should include pre- and post- excavation survey of excavation area by a licensed surveyor to ensure area is returned to original grade and that surface water drainage is towards the Cheboygan River.

2. Section 01025 Measurement and Payment paragraph 2.c.i requires a licensed surveyor and Section 026100 Excavation and Handling of Contaminated Material paragraph 3.3.C.1 states that the Professional will be responsible for staking the excavation. Are these two separate things? No, the licensed surveyor should be responsible for the pre- and post-excavation survey and for staking the excavation area. All survey data should be delivered to the Professional in electronic format.

3. Could you please clarify the excavation depth for this project as it appears that there is conflicting information between the Bid Summary Project Scope of Work, Section 01010 Summary of Work, and Section 026100 Excavation and Handling of Contaminated Material.

The depths listed in the Bid Summary Project Scope of work are correct. Area 1 is approximately 1,300 sq. ft with an excavation depth of 3.0 feet below ground surface and Area 2 is approximately 1,590 sq. ft with an excavation depth of 2.0 feet below ground surface.

4. We would just like to verify quantities in the bid schedule. If we remove 393 tons of excavated material and fill with 407 tons of clean material, would that get us back close to existing grade? Then if we add 87 tons/6” of gravel on top, would that put us above existing grade? These are estimates and the difference in tonnage is due to the estimated weight of existing material being removed and the estimated weight of fill material. The difference is related to the composition of the fill sand/gravel as well as the estimated compaction factor. In the Bid Schedule, the Item Bid Price should utilize the provided estimated tonnage and the Unit Price should list the cost per ton for excavated material, fill material, and gravel top layer. Payment will be based on the actual recorded tons of excavated material, fill material, and gravel top layer.

ACKNOWLEDGEMENT: This Addendum must be acknowledged by the Bidder in the space provided in the Bid Summary and Bid Form. Failing to acknowledge Addenda may be cause for the Bid to be http://www.michigan.gov/SIGMAVSS rejected. Addenda will become part of the Contract Documents.
