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.

This online engineering PDH course introduces engineers to the National Society of Professional Engineers Code of Ethics. The Code provides ethical guidance to engineers in their various and often simultaneously held roles as 1) guardians of public health, safety, and welfare 2) employees, 3) employers, and 4) providers of technical service to clients.

 

Engineers practicing their profession encounter not only technical issues but also ethical issues. Sometimes the latter issues are easy to resolve: applying everyday, common-sense notions of honesty, openness, responsibility, and lawfulness is sufficient to guide the engineer to the appropriate decision. At other times, however, matters are more complicated. In particular, knowing what to do when two or more duties or obligations conflict can be difficult. For example, an engineer's duty to his client or employer may conflict with the engineer's duty to the general public. Codes of ethics have been formulated to help engineers address these conflicts.

 

This 1 PDH online course is intended for all engineers who are interested in gaining a better understanding about how to protect and respect their engineering profession in the utmost manner.
