To begin, a work area will have to be prepared. An accessway may need to be constructed should the route of travel not be suitable to support the heavy equipment that will be used in this operation. This can take the form of temporary access roads made of geotextile fabric and an aggregate of some sort, or a temporary structure may be required. This is all dependent upon site conditions and design requirements. The proposed installation area will be cleared and made reasonably flat and level. Further, any ground preparation will be performed as necessary to facilitate construction. A plethora of equipment including a crane of sufficient capacity will be brought on site along with a set of pile leads, a pile hammer, and a power source for the hammer.
Over the years, new technologies have been developed and subsequently, a multitude of pile types currently exist and are used throughout the world. The Cast-In-Place (or CIP) pile, as it is commonly referred to in the industry, is the topic of this paper. The typical CIP pile is constructed in order to support a structure or function as some type of structure in and of itself. They are used for building support, bridge support, utility support, and for many other purposes. To begin, a work area will have to be prepared. An accessway may
Next, steel pipe pile shells would be brought on-site. These piles may require splicing, which is the joining of two or more sections to make a single pipe section, and the installation of points on the end of the pile of some sort if required. The pile leads will be assembled and raised to a vertical orientation by use of the crane. In certain situations, the pile could be installed on a slant. In this case, the pile leads would be held in the slanted orientation for driving piles. This would be called a “battered pile” and is used to combat the sliding and/or overturning of a structure. The hammer will be installed in the leads and the crane will raise it to an appropriate height. The pipe pile will then be raised by the crane until it is completely within the leads and the entire assembly will be positioned
Roy Huemer, CPE Garden State - 26 Roy@huemerllc.com His career in construction began in 1986 and he currently trains estimators as well as consulting contractors in many fields of construction, educating them in the art of estimating and cost estimating. He began his career in construction as a laborer working for a residential home builder. He later worked for civil design engineers as a draftsman. There he acquired skills in construction survey which led him to the field of heavy highway construction. He joined the estimating group of contractors active in the New Jersey heavy civil construction field. Over the next 20 years, he gained the knowledge and experience to work, estimate, and manage heavy civil construction. He has also trained estimators in the general contracting, electrical, and mechanical fields as well as many other contracting disciplines.
