About this file
This file contains engineering design plans for a horizontal directional drill (HDD) project. Key details include specifications for installing 8-inch plastic pipe beneath a critical control point using HDD with a minimum bore radius of 300 feet, entry and exit angles not exceeding 6 degrees from horizontal, maintaining drilling fluid circulation, and securing entry and exit points with concrete utility boxes. The contractor must survey and video the installed pipe, collect pilot bore tracking data every 15 feet, and fuse blind flanges and seals to pressure test and seal the pipe ends.
The related federal contract opportunity is a solicitation from the Department of the Army Corps of Engineers Engineer Research and Development Center to develop an HDD experimental site at their facility in Vicksburg, Mississippi. Services required include installing underground utilities using HDD in accordance with the engineering design plans provided.

CRITICAL CONTROL PT.
AutoCAD SHX Text
1. Min bend radius shall Min bend radius shall be 300' or larger. (TYP ALL) 2. HDD pipe shall be HDD pipe shall be horizontal and flat when boring beneath the Critical Control Point. Bore path shall be a minimum of 10' but no more than 15' below the Critical Control Point identified herein. 3. Entry/Exit angles shall Entry/Exit angles shall be drilled at no greater than 6 degrees from horizontal unless approved in writing prior to installation. 4. Contractor shall Contractor shall maintain full drilling fluid circulation at all times to minimize the risk of inadvertent drilling fluids escaping to the ground surface. 5. Concrete utility boxes Concrete utility boxes shall be used to secure and protect the installed pipes at entry and exit locations. 6. Bland flanges shall be Bland flanges shall be fused to both ends of the installed pipe along with all seals and hardware to pressure test and prevent water intrusion post-testing. 7. Contractor shall survey Contractor shall survey and video the entire length of the installed pipe post-HDD and hydrostatic test. 8. Pilot bore tracking data Pilot bore tracking data shall at minimum be collected every 15' STA to ensure precise line/grade control.
