Inquiry #1: Please allow more time (72 hours or greater) for the contractor to pave the RHMA-O after the cold plane operation is performed. Currently the special provisions are silent on this issue and it automatically defaults to requiring the contractor to paveback the milled surface during the same shift. Since crackfill is required in between the cold plane operation and RHMA-O operation, and the Crackfill material needs to cure prior to RHMA-O paving, productivity (short paving window) and quality issues (smoothness - added joints) will arise.

Response #2:
Your inquiry doesnt appear to be applicable to this contract. There is no RHMA-O or crack treatment included in the plans or estimate. In addition, per section 39-3.04A of the Special Provisions, the contractor does have 72 hours to pave after cold planing as long as the milled surface is covered prior to the weekend.

Inquiry #2: The electrical sheets 314 through 391 are very faint (light) and it's difficult to determine what's existing and what's new, is there anyway a clearer scan can be loaded for these sheets that bolds the new and the faint (light) is existing? On the modified standard and equipment schedule the * denotes new equipment, if the * shows up for a new pole is all the equipment new as well? For example on sheet E-3, sheet 616 of 459 * pole "A" 26-4-100 are the (2) MAS, SV-1-T, SP-1-T and Roadway 1 luminaire all considered to be new?

Thank you

Response #2:
1. The light print on the electrical plan sheets is due to the printer. The plans were printed and reviewed in response to this inquiry and no printing issues were found. Your attention is directed to RSP ES-1B to show further differences between what is existing and what is new.

2. Yes, the * denotes all new equipment.

Inquiry #5: Reference Bid Item #123 - Adjust Utility Cover to Grade. Basis / scope for quantities is unclear or considerable adjustment of bid item quantity is needed. There appears to be 47 each called out by individual lines tied to each "adjust" note on the "Utility Plan" sheets. Many have multiple lines pointing to adjust locations, however only Sheets U-16 and U-18 specifically note more than 1 adjustment in the note verbiage. The note callout per sheet to "adjust" is also considerably higher that the bid item quantity of 12 each. Please clarify the basis of the quantity, correct the bid item quantity as required and include a summary table detailing the adjustments and which utility type the cover belongs to (water, sewer, etc,..).

Inquiry #14: Reference Plan Sheet DD-1 detail for "Underdrain Modified Cleanout Cover" and Bid Item #103 (8" Perforated Plastic Pipe Underdrain). There is no project specific detail for the underdrain pipe installation, therefore it is assumed that Standard Plan D102 applies which calls for fabric lined trench and permeable material backfill over top of pipe up to the grading plane. However the project specific detail on DD-1 calls for "Conc Backfill (Pipe Trench)" around the vertical riser. Please clarify the intent (dimensions, where required, etc,..) of the concrete backfill since the standard plans do not require any concrete backfill above / around the pipe trench. Additionally, please clarify the quantity of underdrain cleanouts required per detail on DD-1 or minimum requirements to assume (maximum feet spacing between cleanouts, all angle points, etc,..). The project plans and standard plans / specifications do not clarify this requirement and therefore the bidder can't quantify / determine costs accurately since incidental to the LF underdrain pipe cost.

Inquiry #16: Addendum #1 re-issued Plan Sheet C-56. This detail updated the details for "adjust manhole to grade" and "adjust utility cover to grade". Both of these details show rapid setting concrete being required in the collars around the utility, therefore it would appear they are required for the 1 EA manhole and all 47 EA utility covers. However the note under the utility cover detail says to "See Sheet U-16 and U-18" which would imply only the utility covers on those sheets get adjusted per this rapid setting concrete detail. The vast majority of the 47 EA are on other "U" sheets, therefore clarification is needed as it impacts costs considerably. Please clarify if the new details on Sheet C-56 (specifically for rapid setting concrete) apply to all manholes / utility covers being adjusted as part of the project under Bid Items #122 and #123.

Inquiry #18: For Bid item #42 (Concrete Backfill over Existing NID Pipe), additional information is needed to clarify the CY of backfill. The detail provided on Sheet C-56 does not provide set dimensions for the pipe backfill / cap. This information is critical since this is a final pay item. Please see the following questions:

1) What is existing NID pipeline outside diameter that bidders should assume (concrete cap width required to be pipe outside diameter plus 4' minimum)?

2) What is existing NID pipeline depth that bidders should assume (concrete cap required to start at 6" above the pipe and be poured up to within 0.20' of finished grade)? Assuming a typical minimum depth (+/- 2' to 3'), it appears the bid item quantity is considerably low for CY of backfill needed.

Inquiry #19: Follow up clarification is needed to Inquiry #14. Please see the following questions:

1.) For the underdrain, confirm Standard Plan D102 applies which calls for a fabric lined trench and permeable material backfill over top of pipe up to the grading plane. If not, please provide a detail or clarify which standard plan applies.

2.) For the "Underdrain Modified Cleanout Cover" on Sheet C-56, it is assumed this applies to all 18 EA cleanout risers required. Is the intent of this detail to install an 8" tall concrete backfill collar around each riser pipe, approx. 2" thick in between each riser and frame?

3.) For the "Underdrain Modified Cleanout Cover" on Sheet C-56, please confirm no concrete backfill is required above the mainline pipe trench (pipe backfill, pipe cap, etc,..) with exception for the small collar between riser pipe and frame referenced in previous question #2 of this inquiry.

Inquiry #23: Fiber Optic Scope of Work - E Drawings indicate a 96 SMFO trunk cable along the project. At most locations but not all they indicate a splice enclosure to be installed in 6E boxes. No where does it indicate except 1 location that a drop cable be installed from the cabinet to the 6E where the splice is housed. I am assuming you would like a drop cable installed? ED-1 Through ED-3 Indicate that most cabinets get 24 strand terminations and 3 cabinets get 48 strand terminations. Is this correct? ED-4 indicates that there is just 1 -12 strand incoming to the cabinet (even though it shows 2-12 strands in the picture) then says to terminate all fibers in the cabinet and only splice the strands needed at the splice location. With all that said do you just want 1- 12 strand drop cable installed from the splice vault to the cabinet and terminate all 12 strands as that would take care of the needs of all the needed fiber circuits in the cabinets. Could the drop cable requirement for each location be added to the drawing set?
