Unfortunately, HDD specifications often fall short of effectively communicating project expectations. The adoption of HDD for the installation of underground utilities and pipelines has increased over the past two decades further necessitating the need for comprehensive specifications. A poorly written specification does an inadequate job of communicating the owner's expectations and is generally the cause of construction claims. Specifications serve as the tool to communicate the requirements and expectations of the owner and the owner's representatives, and are the foundation for the construction documents that contractors rely upon to build the project. This is especially important when engaging in horizontal directional drilling (HDD) projects given the general lack of knowledge of the technology by the design community. Additionally, the paper discusses the new Maricopa Association of Governments (MAG) Specifications Section 608 "Horizontal Directional Drilling", which was released in January 2016.Ībstract = "Contract specifications are critical to the success of all construction projects. Examples of both effective and ineffective HDD contract specifications are discussed, demonstrating the consequences of poorly written specifications. This paper discusses some of the key elements for developing a successful horizontal directional drilling specification as well as identifying some of the pitfalls to avoid. In many cases, these specifications are constructed by "cutting and pasting" sections from numerous specifications thus often being unrealistically restrictive or falling short of addressing critical issues specific to HDD. This will also help to slow down swelling, clean the drill bit, and help with the soil suspension and removal.Contract specifications are critical to the success of all construction projects. This Premix provides additional secondary filtration control and High Viscosity.It will produce minimum 150 barrel yield. Our High Yield Sodium Bentonite and Viscosifier premix can be used for all type of soil including reactive clay such as sand and rock for HDD trenchless application.
