Addendum No.10 CONSTRUCTION OF THE NORTH BAY ROAD PEDESTRIAN EMERGENCY BRIDGE CITY RFP NO. 14‐09‐01 2 underway concurrent with the bridge construction. The drainage scope of work is currently included in the 174th St project (By Others) and as such, the cross sections are depicted as existing. Extensive coordination with the 174th St Contractor will be required as part of this project. In the event the drainage project is delayed or withdrawn, the City will solicit additional pricing from the contractor for this Emergency Bridge project to construct the outfall and related drainage improvements. Q3: Typical section sheet 4 shows an interior barrier wall adjacent to the 5’6” sidewalk. MSE plans and roadway plans do not show this wall. Will revised drawings be provided for the typical sections, MSE or roadway drawings? A3: The plans have been revised to eliminate the interior barrier wall. Q4: Typical section sheet 4 shows a pedestrian barrier wall, but does not show a sidewalk or standard moment slab. Which moment slab detail should be followed here? A4: The Roadway Drawings have been revised to show the standard moment slab/junction slab of the MSE Wall Details. Q5: Ground improvement are shown from 20+70 to 21+70 and 24+12 to 26+40. Will any demucking be required beyond this area? A5: The limits of demucking will be dependent upon the means and methods employed by the contractor noting that the plan data is based upon the conditions found at the individual boring locations. While best professional efforts and due care were put forth in quantifying this item, field conditions may or may not match these limits exactly. The contractor shall satisfy himself of the limits of muck that must be removed for the project be constructed in accordance with the plans and specifications. Refer to Note 2 on Sheet BW-1 of the Bridge Drawings. Further, the regular excavation and embankment volumes shown in the plan sheets have been calculated without regard to subsoil excavation because the contractor is responsible to choose from the method of soil improvements shown in the Geotechnical Report, which was issued with and is a part of the contract documents. The chosen method of soil improvement would impact the volume, so the excavation and embankment volumes are calculated based upon the existing ground surface elevation. The contractor must account for the differential cost of excavation and embankment in the cost of soil improvement
