Horizontal Directional Drilling It is TCB's opinion the request for the proposed alternate construction method of HDPE by directional drilling for the three sections is technically acceptable provided the following conditions are met: · This proposed alternate construction method results in no additional contract time or cost to the Owner. · The Contractor shall prepare proposed plans showing the horizontal and vertical alignments for these three sections. These shall be in the form of marks on the plans. Clearly show where the DIP transitions to HDPE. Show thrust anchors at each end of the HDPE. These plans shall be reviewed with TCB and the City's Inspector prior to beginning directional drilling. Required clearance of the new force main below existing utilities shall be i0 feet desired, 8 feet minimum. The pipe manufacturer's recommended minimum bend radius for the 20-inch DR 17 HDPE piping is 27 times the pipe outside diameter for piping and 100 times the pipe outside diameter at flange adapters. These minimum radii shall be maintained at all times. Air release valve must be provided at all high points. · Once directional drilling ora section is complete, the Contractor shall provide as-built data for the actual horizontal and vertical alignments installed. This data shall be in the form of marks on the plans. TCB will use these marks in drafting "record drawing" plans for the City at the completion of the project. Survey data (coordinates and bearings) will be required. · TCB has not reviewed the experience, qualifications, or equipment of the proposed horizontal drilling sub-contractor. Downsizing of Bored Steel Casing Diameter TCB has no objection to downsizing of the bored steel casing diameter as proposed by the Contractor, with the understanding that the Contractor assumes full responsibility for the more difficult installation in smaller casing. The total amount of the savings, as calculated by S.J. Louis, is $13,420. The proposed split of half of the total savings to the City and half to S.J. Louis is acceptable.
