Delaware Civil and Ethics 24 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 addresses EPA's BMP for the protection of wetlands and aquatic ecosystems, protection of public health, flood control and more.

 

Erosion and sedimentation related to construction site storm water runoff can significantly affect the aquatic population and hydraulic characteristics of the receiving waters. Alterations in hydraulic characteristics of streams receiving runoff include higher peak flow rates, increased frequency and duration of bankfull and subbankfull flows, increased occurrences of downstream flooding, and reduced baseflow levels.

 

EPA recognizes that such alterations can be prevented by implementing an effective storm water management program.  Therefore the EPA published the Storm Water Phase II Rule on December 8, 1999, that describes a menu of Best Management Practices (BMP). “Construction Site Storm Water Runoff Control” is one of the Best Management Practices that requires operators of small MS4s in urbanized areas to implement a storm water management program for the protection of wetlands and aquatic ecosystems, improved quality of receiving water bodies, conservation of water resources, flood control, and protection of public health.

 

This 2 PDH online course is applicable to municipality owners and/or operators, construction contractors/workers, site developers, engineers, managers, and all other personnel involved in the implementation of runoff controls for storm water runoff from construction sites.

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 engieering PDH course provides instruction in engineering ethics through a case study of the Space Shuttle Challenger disaster. The minimum technical details needed to understand the physical cause of the Shuttle failure are presented. The disaster itself is chronicled through NASA photographs. Next the decision-making process, especially the discussions occurring during the teleconference held on the evening before the launch, is described. Direct quotations from engineers interviewed after the disaster are used to illustrate the ambiguities of the data and the pressures that the decision-makers faced in the months and hours preceding the launch. The course culminates in an extended treatment of six ethical issues raised by Challenger.

 

This 3 PDH online course is intended for all engineers who are interested in gaining a better understanding about the ethical issues that lead to the Challenger disaster and how they could have been avoided.
