District of Columbia Civil and Ethics 20 PDH Discount Package 2

This online engineering PDH course provides information and guidance on the use of RCC in dams and other civil works structures. Elements discussed include investigation and selection of materials, mixture proportioning, design and construction considerations, construction equipment and techniques, inspection, and performance.

 

The American Concrete Institute (ACI) defines roller-compacted concrete (RCC) as "concrete compacted by roller compaction; concrete that, in its unhardened state, will support a roller while being compacted." Properties of hardened RCC can be similar to those of conventionally placed concrete. However, RCC can also be made with hardened properties that are outside the range of typical properties of conventionally placed concrete. The term "roller compaction" is also defined by ACI as "a process for compacting concrete using a roller, often a vibrating roller."

 

RCC may be considered for application where no-slump concrete can be transported, placed, and compacted using earth and rock-fill construction equipment. Ideal RCC projects will involve large placement areas, little or no reinforcement, and little or no embedded metal work or other discontinuities such as piles. Application of RCC should be considered when it is economically competitive with other construction methods. It may be considered in lieu of gabions or riprap for bank protection, especially in those areas where riprap is scarce. It may be considered for large work pads, aprons, or paved areas, massive open foundations, base slabs, cofferdams, massive backfill, emergency repairs, and overtopping protection for  embankment dams. It may be used in lieu of conventionally placed concrete in concrete gravity and arch-gravity dams. RCC may be considered for use in levees where foundations are adequate and may also be used in caps for jetties to reduce the amount of required rock.

 

This 8 PDH online course is applicable to civil, structural or geotechnical engineers, as well as design and construction personnel involved with the planning, design, construction of roller-compacted concrete structures.

This online engineering PDH course provides guidance in hydrologic analysis of interior areas for planning, design investigations, and flood risk reduction.

 

Floods have social, environmental, and economic consequences and they directly impact people and communities. Some of the immediate impacts of flooding includes loss of human life, loss of livestock, and damages to properties and crops.

 

This course provides information of interest to planners and designers of interior system involving flood loss reduction measures and actions. Interior area investigations are differentiated from other studies only by the uniqueness of the hydrologic analysis requirements for the flood loss reduction measures commonly used. Interior area planning studies are an essential aspects of feasibility studies.

 

This 11 PDH online course is applicable to civil, environmental, and stormwater management engineers as well as other technical personnel interested in learning more about hydrologic analysis of interior areas.

In this online engineering PDH course, ten case studies of actual enforcement actions taken by a state licensing board are presented. The cases have been selected to be representative of situations likely to exist in many states.  Board procedures and the types of enforcement actions available are shown by a variety of cases ranging from a geotechnical engineer who produced (within one hour and without visiting the site) a soils report, to an engineer who was unable to document his PDH's during a board audit.  The importance of being very careful about when to put "P.E." after one's name on a document also will become apparent.

 

Codes of ethics for engineers typically describe standards for professional behavior. The enforcement of those ethical standards that are inscribed into law lies with the licensing boards of state governments.

 

This 1 PDH online course is intended primarily for all engineers seeking to deepen their understanding of what constitutes ethical and professional engineering behavior and how such behavior is enforced by the licensing board.
