There are times when sewage pumps must be used to get sewage to a septic system. The pumps are normally installed in a buried box outside of the building being served. The box is often made of concrete. In these cases, the home’s sewer pipe goes to the pumping station. From the pumping station, a […]
Land development and management
The minor lay lords of the middle ages were all too often uninterested in the management of the land, or sometimes were simply incapable of applying techniques that went beyond their competence. So it was the monks, and in particular the Benedictines and Cistercians, who became the custodians of land development during the demographic expansion […]
Information Phase
Objectives. The first phase of the job plan has two basic objectives: To obtain thorough understanding of the project, system, operation, or item under study by a rigorous review of all of the pertinent factual data To define the value problem by means of functional description accompanied by an estimate of the cost and worth […]
Resistance to Fuel on Airfields
This requirement regarding resistance to fuel exclusively applies to SMA mixes for airfields. The method of testing this property of SMA is elaborated in the standard EN 12697-43. The categories of the requirements are good, moderate, poor, or NR (no requirement). 14.5.11 Resistance to Deicing Fluids for Application on Airfields This requirement concerning resistance to […]
Multiple-Framer Tasks
Some tasks require more than one framer, for example, lifting large walls. Any time framers have to be called from other tasks to perform a common task, care must be taken not to waste time. The cost per minute of a 5-framer task is 5 times that of a single framer task. The person organizing […]
Additional Conditions for Preparing Samples
The SMA wheel tracking test is carried out on samples (slabs) prepared in a laboratory or cut out of a pavement. Additional requirements for samples may be determined in the following two ways: • Requiring a void content in the slab; in this case the requirement has a range of 3% (v/v), (e. g., 3-6% […]
Radio Frequency Radiation
The higher the frequency of the electromagnetic radiation, the more the electric and magneticfield components meld. The energy level of radio frequency (RF) radiation is billions of times stronger than the natural high-frequency energies from the cosmos that existed during our biological development. Research shows that cataracts, blood composition changes, hormone alterations, and chromosomal abnormalities […]
VALUE ENGINEERING JOB PLAN DETAIL
The VE job plan outlines those tasks or functions necessary to properly perform a VE study. Adherence to a definite plan is essential to achieving optimum results. Good results come from a good system, and a good system is one that covers all aspects of a problem or situation to the necessary degree. Use of […]
VALUE ENGINEERING JOB PLAN CONCEPT
As discussed by Wilson (see David C. Wilson, “Value Engineering Applications in Transportation,” NCHRP Synthesis 352, Transportation Research Board, 2005), the VE process may be referred to as the job plan, a defined sequence of activities that are undertaken before, during, and after a VE workshop. During the VE workshop, the VE team learns about […]
Sealing Systems for Environmental Protection
13.5.1 Sub-Soil Barriers Sealing systems can be laid during construction to prevent contaminated water from moving in an undesired direction or to keep natural groundwater separate from contaminated road runoff and road construction seepage waters. In many places in which geomembrane barriers could be placed, spillage of petroleum and diesel from vehicles is a possibility. […]
