Pipelines 2015: Recent Advances in Underground Pipeline Engineering and Construction - Proceedings of the Pipelines 2015 Conference | Year: 2015

A water utility located in the Southern US provides water to over 16,000 customers and wastewater service to over 13,000 customers across two counties. In order to serve a growing population, the utility is in the process of upgrading its water treatment plant from 51 MGD to 62 MGD. As a part of the construction process, soil nails were installed for excavation on the property. During the implementation of these soil nails, two 6-inch diameter punctures were made in a 54-inch Prestressed Concrete Cylinder Pipe (PCCP) and 45-degree steel elbow respectively. Given that this pipeline is the main raw water line for the treatment plant, and that the damage occurred during peak summer demand, the need to repair the line was urgent. The proximity of multiple bends and steep slopes adjacent to the distressed regions of the pipelines posed significant challenges for replacement. After extensive research and a site visit to a large municipality pipeline project utilizing similar technology, the utility proposed an internal structural repair using carbon fiber. The owner's options analysis process, implementation of the bypass system, as well as the internal repair will be detailed in this paper. © 2015 ASCE.

Experts suggest that potential geothermal designers need to consider geothermal heating and cooling options when designing and installing such systems. They need to remember that there are three general types of geothermal systems, such as open loop, closed loop, and hybrids. Open loop systems use a dedicated well with a submersible pump as the source of water delivered to the heat pump. Hybrid systems use some piping and an evaporative cooler and designers can get creative in using different types of loops to achieve the best results for cost and energy savings. Designers can save money on installations by examining heating against cooling load and size piping for heating load and supplement cooling with an evaporative condenser. It is also important to remember that geothermal is on an energy efficiency ratio (EER) rating system, which is different than most conventional equipment.

Not all co-standards"ANSI/UL, for example"are adopted or approved at the same time. For instance, although UL may have written and approved a standard in 2004, ANSI may put it in its next review cycle and the standard may not get approved until several years later. Keeping up with adopted and latest editions of the standards can be a chore, especially when trying to keep a master specification up to date. It is best to talk with equipment manufacturers and review applicable standards regularly with the writing organization's website. As a specifier and designer, it is good to be familiar with the testing and measuring criteria to which the standard applies, so you know what to expect and do not require items that may be irrelevant or difficult to achieve. Reading the standards once in a while is also a good practice to keep informed.

Several tools such as equipment calculation and selection programs, 2 and 3-D CAD drafting, which are employed by mechanical engineers to ensure the efficiency in their jobs are presented. CAD programs and BIM are making the design and construction lives easier by creating ways to design, lay out, and allow multidiscipline coordination in 3-D. The design method allows the team to see how components and systems interface with each other in actual size and location, thus potentially eliminating conflicts and allowing contractors to do their field coordination and installation more efficiently. Energy modeling programs along with the US Department of Health and Human Services and designated ASHRAE standards and codes will edit a heat load on a space-by-space basis, choose the worst case, and indicate that in the output while sizing the ductwork for the space. The tools available to the engineer are important to every project in order to produce work consistently, uniformly, and quickly.

Wet stacking is a term describing a diesel engine dripping a thick, dark substance from its exhaust pipes or stacks. The condition is caused by operating the engine at light load for extended periods, sending unburned fuel and soot into the exhaust system. When the injector nozzle is fouled with carbon, its ability to atomize the fuel is compromised, and it delivers larger droplets to the cylinder. The general cure for wet stacking is a few hours of operation at a load of about 75% of the generator's nameplate rating or more, raising the exhaust temperature high enough to vaporize the unburned fuel in the exhaust system and blow out the soot. A load bank with enough capacity to increase the total test load, including the facility's minimum available load, high enough to reach either the recommended exhaust temperature or the prescribed 30% level, is adequate for compliance. Wet stacking can be avoided by proper generator selection, and by properly performing routine generator testing.

Robert Trotter CBO, CFM, provides information regarding provisions of NFPA code and exceptions to plenum requirements for egress corridors in health care environments. A plenum is a separate space specifically for air circulation for HVAC in the built environment, which is provided in the space between the structural floor/ceiling and a suspended-grid acoustical tile ceiling. Robert Trotter suggests that health care authorities need to consider the advantages and disadvantages of plenum configurations when making design decisions. One of the advantages of plenum configurations is that return plenums significantly reduce installed mechanical costs due to the elimination of all return air ductwork, reduced fan motor and VFD hp, and reduced relief system costs. One of the disadvantages is that using building cavities as return air plenums can draw them below atmospheric pressure due to improper design.

Some of the latest laboratory ventilation code and standard editions that provide good HVAC design, proper airflow, and correct pressure relationships for a project and client, are discussed. Chapter 11 of NFPA 99 (2005 Edition), Standard for Healthcare Facilities, establish criteria to minimize the hazards of fire and explosions in laboratories. The 2006 AIA Guidelines for Design and Construction of Health Care Facilities, as well as the newest 2010 Facility Guidelines Institute (FGI) Guidelines for Design and Construction of Health Care Facilities, list minimum air change rates for laboratories at 6 to 10 air changes/hour (ACH), depending on the space function. NFPA 99 and NFPA 45 cover the quantities of flammable and combustible material allowed to be stored in a lab. The Centers for Medicare and Medicaid Services (CMS) regulates all laboratory testing (except research) performed on humans in the United States through the Clinical Laboratory Improvement Amendments (CLIA).

The replacement of normal fine aggregate with high fines limestone screenings is a technique to reduce waste from crushed stone operations, while potentially improving the durability and performance of concrete. The main objective of this research is to evaluate varying percentages of high fines limestone screenings as a partial weight replacement of reactive fine aggregate (similar to limestone sweetening) in mortars to assess reductions in the expansion due to alkali-aggregate reaction (ASTM C 227, ASTM C 1260, and modified ASTM C 1105). Fresh and hardened properties have been evaluated to assess the effects of limestone screenings on performance criteria. Environmental scanning electron microscopy (ESEM) was performed to visually observe and confirm alkali-aggregate reaction products and associated damage. From the physical testing and microstructural analysis, it was found that 50% or more of limestone screenings significantly reduce expansions due to alkali-aggregate reaction, attributed to the preference for monocarbonate formation in the presence of limestone and/or reactive silica dilution. Replacements less than 50% did not significantly reduce expansion. © 2016

A system and method for collectively indexing a collection of documents in paper or electronic form. The collective index is created for all documents, which may come from a variety of sources and be initially presented in a variety of formats. Documents are converted to a standard electronic format, then analyzed and processed to identify, locate, and tag objects of interest. Hierarchical menus are created with multiple categories.
