Online Wall eLearning

Asbestos Awareness This course is intended for all persons who could come into contact with materials that might contain asbestos. The largest group of employees covered by this regulation are maintenance and custodial workers, since many materials commonly used in buildings for many years (including ceiling tiles, vinyl flooring, and wall and pipe insulation) contain Asbestos. This means that the regulation applies  more...

Crawlspace Construction of Buildings Located in Special Flood Hazard Areas ...een established because below-grade crawlspace foundation walls are exposed to increased forces during flood conditions, such as hydrostatic and saturated soil forces. In many parts of the country, a common practice is to construct crawlspaces with the interior floor 1 or 2 feet below-grade by either (1) back-filling against the exterior of the foundation wall or (2) excavating the crawlspace  more...

Insulation Basics ...nd installation details for slabs, underground foundation walls, exterior above ground walls, ceilings, attics and roofs. Although the building codes for commercial construction are different than those for residential construction, some of the insulation principles that apply to residential construction also apply to commercial construction. In this course, the student will learn some of the  more...

Lateral Earth Pressure for Non-Geotechnical Engineers ...th pressure (at rest, active and passive) that apply to a wall or bulkhead and describe how each is calculated. The course also describes other types of lateral pressure that might act on a wall. The total lateral force acting on a wall then, is derived from the lateral earth pressure force plus any additional lateral forces that might apply. A basic example is provided in the course material.  more...

Retaining Walls for Non-Geotechnical Engineers ...capacity, which are three elements required for retaining wall design. A basic example of the calculations for the Rankine method is provided. When this course has been completed, the reader will be familiar with calculating the active earth pressure force and applying it to determine the factors of safety with respect to sliding, overturning and bearing capacity relating to retaining wall  more...

The Physics of Mold ...he evaluation method for designing and building composite walls in different climatic zones and to give a tool for the designers to avoid mold development. Case studies highlight the pitfalls of inappropriate wall section designs. This course has no specific prerequisites; however knowledge of psychrometrics is a plus in understanding the physics of vapor migration and condensation. The  more...

Structural Design Criteria for Permanent Wood Foundations ...n system that is a load-bearing, lumber-framed foundation wall sheathed with plywood that can resist and distribute earth, wind, and seismic loads and stresses that may crack other types of foundations. All lumber and plywood used in the construction is pressure-treated with preservatives to withstand decay from moisture and insect damage. Use of PWF construction is accepted by major building  more...

Structural Design Criteria for Raised Floor Systems ...n system that is a load-bearing, lumber-framed foundation wall sheathed with plywood that can resist and distribute earth, wind, and seismic loads and stresses that may crack other types of foundations. All lumber and plywood used in the construction is pressure-treated with preservatives to withstand decay from moisture and insect damage. Use of PWF construction is accepted by major building  more...

Construction of Residential Buildings in Coastal Areas ...t-and-beam foundation, compared to building on continuous wall foundations The additional care that must be taken in constructing a building envelope that will withstand the intrusion of air and moisture under the effects of high wind speeds This course discusses the construction aspects of the above challenges, as well as basic aspects of the coastal construction process and is divided  more...

Segmental Retaining Wall Design ...walls are becoming an increasingly popular option where retaining walls are needed. Architects and developers like them because of their aesthetic value compared to a masonry block wall or plain concrete surface. Contractors like them because in many cases they are faster and easier to install than reinforced masonry or reinforced concrete walls. The course gives a brief description of  more...

DC Power Supplies Fundamental Concepts ...y connected to a house or office AC (alternating current) wall outlet. These include radios, stereo systems, TV, computers, and other devices which we use daily. The discussion starts with the primary power source - the wall socket, and a brief history about AC power. Several basic power supply configurations are described to support the functional concepts introduced. Features such as voltage  more...

Laboratories Best Practices Commissioning Containment Systems ...ment has commonly been delivered and installed as off-the-wall selections considered state-of-the-art by default if not by superior design. However, with advancing technology of ventilated containment systems and with heightened concern over material hazards, environmental protection and energy conservation, equipment efficacy must be assured. Consequently, commissioning has become an essential  more...

Liquid Pipeline Hydraulics ...ough a pipeline using batching methods Calculating pipe wall thickness based on MAOP State Board Acceptance This course can be used by professional engineers to fulfill PDH requirements mandated by state and provincial licensing boards. Decatur Professional Development is an approved provider of continuing education in all states that pre-approve course providers. In all other states  more...
