Virginia Civil 16 PDH Discount Package 2

This online engineering PDH course describes the wide array of impact reduction and site design techniques that allow engineers and planners to create stormwater control mechanisms that function in a manner similar to that of natural control mechanisms.

The low-impact development (LID) approach combines a hydrologically functional site design with pollution prevention measures to compensate for land development impacts on hydrology and water quality. The primary goal of Low Impact Development methods is to mimic the predevelopment site hydrology by using site design techniques that store, infiltrate, evaporate, and detain runoff. Use of these techniques helps to reduce off-site runoff and ensure adequate groundwater recharge. Since every aspect of site development affects the hydrologic response of the site, LID control techniques focus mainly on site hydrology.

This 7 PDH online course is intended for civil and environmental engineers and planners as well as construction professionals who are interested in learning about low impact development design techniques and their applications.

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 introduces the reader to the essential methods for designing water efficient landscaping.

Providing an adequate supply of fresh water to our ever growing population is reaching a critical stage.  The World Bank reports that water shortages threaten the health and economy in 80 countries.  With dwindling supplies, the cost of this precious resource is bound to increase.  In response to the declining supply of fresh water, many conservation efforts have been focused within homes and businesses.  Efficiently managing our outdoor use of water can also yield a significant savings to our net water budget.

Designing water-wise landscapes can result in many benefits.  The conservation of our vital water supply is the most obvious.  Water saving landscapes can also decrease energy use, water bills, erosion, and maintenance costs. Some up front thoughts built into the design of landscaping features can save thousands of gallons of water in the long run.  Knowing the key design and maintenance considerations for low water use landscaping is essential for the successful conservation of our most precious resource.

This 1 PDH online course is intended for homeowners, practicing engineers, contractors, developers, regulators, and all other personnel involved with the design, installation, and maintenance of landscaped areas.
