See Sheets 20(7) and 20(7C) for conduit and junction boxes associated with the Aesthetic Lighting Bridge Conduit System (MSE WALL). Inset A on sheet 20(7) shows in more detail the conduits associated with the Aesthetic Lighting, VDOT Power, VDOT Communications and Roadway Lighting. General Note 2 on sheet 20(7C) states that one conduit line is shown for clarity if multiple conduits are within close proximity. Refer to the Sheet Notes for more information related to the Aesthetic Lighting and other conduits represented by the line style. Refer to Sheet 23(14) for the Bridge Conduit System for MSE Walls.

The regular excavation does not include the excavation for the installation of the ground improvement piles. The structure excavation quantity shown in the summary table on sheet 21(1) is for the excavation associated with the ground improvement piles and is calculated to the bottom of the pile cap.

Micro-Tunneling contractors have grave concerns about the Dbl. 42” PCP under Newton Rd. (Str. 4-36). the top pavement at Sta. 23+50 is 13.11 and the top of the 42” Direct Jack Cl-5 RCP is 9. 89. This leaves a clearance of 3.22’. This does not take into consideration what the pavement section is currently. They believe the road will heave and damage the pavement due to the shallow depth. They feel that unless the pipe run is not lowered at least 4’, they will not be able to do it. If this is the case it would have to be done by Open Cut.
Can this pipe run be lowered or done by open cut method?

The 42” pipe cannot be lowered without impacting several utilities. There are three major utilities located within the limits of this crossing: (1) A 24” gravity sewer has an invert of approximately 0.00; (2) a proposed 48” HRSD offset has an invert of approximately -1.75 to maintain a minimum of 3’ cover from the 42” pipe; and (3) a relocated 8” gas line with a top elevation of approximately 2.5’. The current maintenance of traffic plan is based on the pipe being placed using the jack and bore method. If the contractor would like to place the 42” pipe using the open cut method, then the contractor would need to submit a revised maintenance of traffic plan with sequence of construction for approval.

Bid items 5540, 5550, and 5560 list LED Luminaires of 150W, 250W, and 400W. the plans provide the ISO curves for the fixtures, but there are no lumen output levels or other information provided in the plans or specs. On average, LED luminaires have around 100 lumen/watt outputs, which would put the light levels in the areas where these luminaires are proposed at high values with the 150, 250, and 400W fixtures. Are we to provide LED fixtures that are the equivalent of the 150, 250, and 400W HPS or MH fixtures, or are these values actual LED wattage values?

The LED luminaires delivered lumen output is indicated on sheet 15(1A), Note 49. The Contractor shall provide luminaires with lumen output and distribution characteristics per sheet 15(1A) Note 49 and the ISO foot-candle diagrams on sheet 15(2E). The provided wattage of LED luminaires reflect fixtures used for design, as LED technology continues to advance the actual wattage will vary by manufacturer and specific model selected.

The primer for the decorative steel panels steel should be applied in accordance with the specifications and the intermediate and topcoat application should be determined by the contractor. If the intermediate and topcoat are to be shop applied, then any damages during installation will be the contractor’s responsibility to repair. If the intermediate and topcoat are field applied, then any damages or overspray on the steel or adjacent structures will be the contractor’s responsibility to repair.

Line item 5960 (Item Code 61700) Reinf. Steel is for B602 and B603. During the design phase, the steel design for B603 was revised; however, the black bar quantity in the schedule of items was not adjusted. The quantities in the summary tables are correct for each structure for a total quantity of 88,610 LB for line item 5960. The contractor will be paid by the pound for every pound used.

The 48" Force Main and 24" Sanitary Sewer shown on sheets 29(4) & 29(4I) are scheduled to be performed over the weekend according to the traffic plans for Newtown Rd. The bypass and linestop work required to complete these two sewer replacements are very time consuming to install and require a significant amount of space for the equipment. We do not believe the work will be able to be completed and removed from the roadway in a weekends time even if done is sections. Will you allow for single lane closures or lane shifts to accommodate the linestop and bypass equipment which will have to remain in place during the week after the road is opened back up to traffic?

The 48” force main work will require line stops that will remain in place until the relocated force main is connected. The line stops will be protected by traffic barrier service, which is why the MOT plans and quantities include Traffic Barrier Service Reset at this location. Newtown Road northbound traffic lanes will only be closed in accordance with the Allowable Hours for Lane Closures table on plan sheet 1J(0001). There is not a line stop associated with the 24” gravity sewer relocation. The work will require bypass pumping. The contractor will be required to submit a bypass pumping plan.
