    The church was built in 1917 of concrete masonry blocks that were reportedly cast on site by members of the church. The main problem with the church exterior is the delamination of the exterior skin of the concrete block.

    7/22/2014 · Construction
    Constructed in 1934, the "Old Senior Hall" building was built with a structural steel frame, concrete and gypsteel floors and roof, and a reinforced concrete foundation. The exterior walls were built using a brick masonry façade over a clay tile backup with limestone sills, coping, and accents. Active corrosion of main structural members was discovered in the late 1990's, and a plan was developed to renovate the building to address structural concerns. Atkinson - Noland conducted a full exterior condition survey, including use of nondestructive tests to identify the extent of steel corrosion, evaluate masonry performance, and identify potential repair items. Results of this study were used to plan repairs and any necessary strengthening.

    The Health Center building on the Milton Hershey School campus was designed in 1932 as load-bearing masonry construction with steel framing used to support floor and roof loads and loose steel lintels spanning over window and door openings. Atkinson-Noland & Associates was retained to conduct an investigation of the exterior load-bearing masonry walls and structural steel framing for the purpose of identifying typical as-built conditions as well as the locations and severity of any deterioration.

    The 16th Street Mall in downtown Denver, Colorado is a pedestrian and transit mall that extends for more than a mile along 16th Street connecting people to major businesses, hotels, restaurants, and retail. Recently, the street mall pavers have experienced a substantial number of loose and cracked granite pavers. Atkinson-Noland & Associates conducted an extensive investigation at the 16th Street Mall granite tile pavers to determine the causes of distress in the paving system. We also helped develop appropriate solutions to paver debonding, slip-resistance, aesthetics, and maintenance.

    2/26/2014 · Construction
    A six-story condominium building was constructed using load-bearing, concrete masonry with a clay brick masonry veneer. Specifications required that the collar joint be filled during construction; however, the contractor built the masonry without grouting the collar joint. Subsequent negotiation determined that the masonry must be reconstructed with a filled collar joint.

    Despite their history of successful use as fuel system disinfectants and fuel preservatives, antimicrobial pesticide use faces increasing restrictions due to both regulatory control and public concerns. A variety of non-chemical treatments have been used with varying degrees of success to disinfect non-fuel fluids and to at least partially inhibit biofilm development on infrastructure surfaces. Promoters of one technology have claimed successful fuel disinfection and fuel-tank fouling prevention. This paper will review a range of non-chemical treatment technologies and will present the results of preliminary evaluations of several technologies that were tested on Jet A fuels that had been challenged with either Pseudomonas aeruginosa or Hormoconis resinae. Data are presented on treatment impact on adenosine triphosphate (ATP) concentration, culturability and live/dead direct counts in Jet A-1 and on glass microcosm surfaces.

    4/29/2014 · Microbiology
    Several of the major points that I made in 1995 need further consideration, based on both changes in the regulatory climate and field experience with microbial contamination control in surface transportation markets.

    3/25/2014 · Microbiology
    Smaller retailers depend on the expertise and reputations of their suppliers. Traditionally, refiners' attitudes about fuel were that if it met specifications at the time of sales, but failed later, the problem belonged to the owner at that time. As we begin to see impact of the Clean Air Act-driven fuel reformulations, increased consumer awareness and increased susceptibility to contamination, all market participants are going to have to cooperate to ensure that the customer with the engines gets consistently good fuel.

    2/20/2014 · Metallurgy
    Adenosine triphosphate (ATP) assays have been used to quantify bioburdens (biomass) in low-organic-compoundcontent fluids (freshwater, seawater, cooling tower water, and similar fluids) since the early 1950s. The original methodology was labor intensive and required considerable laboratory skill. Over the past half-century, the protocol has been simplified substantially, but until recently, chemical interferences made it impractical to use the ATP test in metalworking fluids (MWF).

    1/17/2014 · Microbiology
    Quantification of adenosine triphosphate (ATP) in fuels and fuel-associated waters was first presented at the Technische Akademie Esslingen 6th International Fuels Colloquium in 2007. At the time, two issues limited the overall usefulness of ATP as a test parameter: inability to differentiate between bacteria and fungi and inability to detect dormant microbes.

    12/11/2013 · Microbiology
    Three alternative, non-conventional test methods are evaluated for their ability to detect and quantify bioburdens in fuel and bottom-water samples. Two of the parameters, catalase activity and adenosine triphosphate (ATP) concentration have been used previously. This is the first report of the use of fluorescence polarization (FP) technology for fuel and fuel-associated water testing.

    In August, 2012 a member of the LinkedIn Metalworking Fluids Group asked for a recommendation for the best biocide/fungicide package to be used to protect a semisynthetic metalworking fluid from biodeterioration. His posting has generated nearly 50 responses. Some of the suggestions were clearly based on limited experience; experience with few MWF, a limited number of MWF systems or both. I posted a number of comments to the string and have compiled them in this article.

    Industrial lubricants are increasingly providing a rich environment for microbial growth and proliferation. Most of the knowledge of lubricant biodeterioration has been extrapolated from field and laboratory experience with metalworking fluids. Compositionally more complex than most lubricants, metalworking fluids are either solutions or emulsions of 5 to 10% coolant concentrate in water.

    9/10/2013 · Microbiology
    As industry seeks to improve the economy of plant operation, responsible managers are paying more attention to factors that affect efficient and reliable operation of their facilities. One area of attention that can payoff handsomely is the control of microbiological activity in coolant systems. Many engineers and plant operations personnel are just beginning to appreciate the effects on their machining operations caused by their plant "biosphere," which contains bacteria, fungus, mold and other contaminants.

    8/14/2013 · Microbiology
    Mounting concerns over operational and waste management costs, as well as the quality and safety of the work environment have provided increased impetus for both formulators and end-users to strive to improve coolant life. There are a number of alterative approaches to achieving this objective. In this paper, the concepts of bioresistance and biostatic are defined and compared.

    7/29/2013 · Microbiology
    This case study reports culture and acid-fast bacteria direct counts from 99 MWF samples received for microbiological testing at Warren, Mich.-based Biosan Laboratories between December 2006 and September 2007.

    7/11/2013 · Microbiology
    All metalworking-fluid formulations share the common problem of susceptibility to microbial attack. This is not all bad news, since we need the used dilute fluid to be biodegradable for disposal purposes.

    6/19/2013 · Microbiology
    During the past decade we have witnessed a tumultuous debate over the disease risks posed by microbes that inhabit metalworking fluid (MWF) systems. Not infrequently, that debate has occurred in the absence of satisfactory data.

    Root cause analysis is the process used to identify the fundamental cause for an undesirable condition. Premature filter failure due either to plugging or other mechanism is generally perceived to be an acute problem.

    Microbes in Fuel Retailing was the last in my series of NPN articles. In it, I presented a more global perspective on the key issues that I had addressed in earlier articles. Since 1999 there have been some watershed changes in the industry since it was written. The most important ones all involve dramatic changes in fuel product composition.

    12/12/2012 · Fuel Systems
    Although the documentation of fuel biodeterioration dates back to the late 19th century, general recognition of the value of microbial contamination control evolved slowly until the 1980's. Since the early 1980's a number of factors have converged to stimulate greater interest in fuel and fuel system biodeterioration.

    10/5/2012 · Fuel Systems
    Adenosine Triphosphate (ATP) is an excellent biomarker present in all living cells. During the past several years, several ATP test methods have been developed to overcome interferences that have historically made ATP testing of fuels impractical.

    7/26/2012 · Microbiology
    Metalworking fluids provide an excellent environment for the growth and proliferation of a variety of bacteria and fungi. Historically, the incidence of infectious disease outbreaks at metalworking facilities has been rare. Consequently the primary focus of microbial contamination control efforts has been to prevent fluid biodeterioration.

    5/21/2012 · Fuel Systems
    Between 1994 and 1999, I had the opportunity to write a series of articles for National Petroleum News (NPN). Each article focused on one aspect of the connection between microbial contamination and operational problems in fuel retail systems.

    This is a personal injury case in which a car windshield was smashed and the driver injured by a tire that "came off" a truck that the car was following on a high-speed interstate highway. The car driver was hospitalized and the car towed. The truck had one of its rear tires replaced and then departed the scene of the accident.

    A London based arbitration process for breach of a contract to purchase tires brought by an International Earthmover Tire Manufacturer, plaintiff, against an International Mining Company, defendant. The Mining Company contractually agreed to order a specified number of tires or to pay 40% of the agreed selling price for any tires not ordered. This is referred to as a “Take or Pay” arrangement. The tire manufacturer contracted to produce tires that met the Tire and Rim Association OTR Handbook standards. The manufacturer did not guarantee tire performance, in terms of any performance measure.

    A common cause of failures in various types of equipment is fatigue failure of bolts that secure parts together. Fatigue in any type of dynamically loaded mechanical component accounts for more than 80% of all failures. This post reviews some important factors in fatigue failure of metallic bolts.

    The working relationship between the attorney and their expert witness in a case can be more effective if a few simple guidelines are followed. These are common sense things but one or more can be overlooked in the frequent day-to-day rush that busy attorneys face. When that happens some of the potential contributions from the expert may be compromised or lost to the detriment of the attorney's client.

    Too frequently an attorney will begin to seek a potential expert witness only after having done considerable initial work. Often there is a last minute rush to locate and select specialized technical assistance. These approaches can have expensive consequences. Alternatively, securing a suitable expert early in the litigation process offers the following advantages for the retaining attorney:

    Many negative consequences can result from failures of a range of different products that often lead to property & casualty insurance disputes or product liability legal actions. The products may include consumer or industrial goods. Typically the private user or worker is injured or a business incurs significant financial loss. The injured individual, insurance carrier, attorney(s) or industrial manufacturer and user are all interested to confirm what went wrong – and who is liable. Resolution often depends on engineering analysis.

    Clearly it is advantageous to know when corrosion is occurring in operating equipment to avoid future failure. There is extensive literature on this topic. This post is a brief summary of information selected from the four references cited below. Each source includes several other references.

    4/7/2015 · Manufacturing
    "3D printing" or the more descriptive term - additive manufacturing (AM) - has received much publicity in recent years. What is this technology and what are some of its practical features? This blog is a summary of AM and its on-going development to make actual service components using metal alloys. Presented are selected portions of information provided in the two references cited.

    3/3/2015 · Corrosion
    Most engineers know about the danger of galvanic corrosion caused by physical contact between dissimilar metals exposed to a corrosive liquid. However, this possibility is often overlooked and other features of this type of corrosion may not be widely known.

    1/21/2015 · Failure Analysis
    It is essential when beginning a root-cause failure analysis involving metallic materials to collect and maintain the as-found physical evidence properly prior to detailed examinations. This has two objectives. In all cases collecting and protecting the evidence in its undisturbed condition provides the best opportunity to derive meaningful good results from the subsequent analyses. Secondly, in a legal proceeding lack of attention to these matters can produce the accusation of spoilation of evidence. As a minimum this will cause presentation problems for the offending party in the suit. At worst such deficiencies by that party may cause the case to be thrown out.

    Aluminum alloy materials are well known for their light weight and strength-to-weight ratios. They are also susceptible to several forms of corrosion. Relative to other metals, their natural electrochemical potential places them adjacent to other very susceptible (active) metals such as magnesium (Mg) and zinc (Zn) in a traditional galvanic series in seawater. However, Al alloys naturally form a very thin, protective (passive) oxide film on their surface when exposed to oxygen. This film prevents corrosion as long as it is maintained over the surface. Pitting corrosion is a common form of attack on aluminum. This is typically caused by exposure to halide ions, chloride ions being the most common type found in corrosive media, that breakdown the passive film at discreet spots. This permits pits to initiate and grow.

    11/7/2014 · Metallurgy
    Often when engineers consider mechanical fatigue they envision cyclic, reversing stresses in a spinning shaft or possibly the up and down flex of aircraft wings. Rolling contact fatigue (RCF) or the associated mechanical wear is an important, closely related process to the traditional mechanism of fatigue but with distinct differences. RCF is also often known as spalling.

    9/25/2014 · Product Liability
    This term raises some vital issues that the engineer should be aware of when using it. First several definitions are available and thus it is perceived differently by different groups and individuals. From a legal standpoint, in many states, using the term to describe a product that was involved in an incident involving an injury means that the designer or manufacturer of that product may be financially liable for the injury. Engineers sometimes use the term simply to indicate an imperfection in a product without intending its frequent legal use. Further the engineer realizes that no material and no finished product is perfect. However, these variations from perfection do not necessarily mean they were cause for failure and thus the injury that may occur in a given incident. Some product liability attorneys may not readily acknowledge or understand this distinction.

    The optimal time to make decisions and take actions to minimize potential failures of equipment, facilities and components is during their design. This two-part blog post provides an overview of the types of issues involved and specific actions that can be useful to the design engineer. Archived blog posts (at www.dmme-engineering.com) that discuss specifics are provided parenthetically.

    Four, tri-lobe pumps were damaged and required extensive repair during the latter stages of construction for a modification in a pharmaceutical manufacturing plant. The economic loss was significant and the general contractor for the work paid the plant's owner for the loss. The renovated units were installed and are in use. However, the general contractor then sued one of its subcontractors - a welding contractor that fabricated and completed weld joints between piping sections on the inlet side of the pumps. The general contractor claimed poor quality welds in the piping permitted loosened weld fragments to enter the pumps during the required water flow verification of the system and this caused the damage.

    Most realize that damage due to corrosion of metals is costly - but what specifically is that cost and what is included in the total? A study completed in 2002 sponsored by the Federal Highway Administration (FHWA), the National Association of Corrosion Engineers (NACE International) and implemented by CC Technologies Laboratories (now part of DVN) addressed those questions.

    5/2/2014 · Corrosion
    Material selection entails picking an engineering material - either metal alloy or non-metal - that is inherently resistant to the particular corrosive environment and also meets other criteria. Variables that will affect corrosion are established along with materials that may provide suitable resistance for those conditions. Obviously other requirements such as cost and mechanical properties of the potential materials must be considered.

    Pin-hole leaks from a fire-control sprinkler piping system just above the false ceiling of multiple rooms in an office building resulted in a suit against three parties involved with supplying the system. The plaintiff - a financial service organization that owned the building - had much computerized transaction data stored on magnetic tapes in several rooms damaged or destroyed by the incident. The monetary loss was major. The leaks occurred within two years after the system was installed. This period is clearly far short of the expected life of the system. Defendants in the case included the supplier of the piping used in the system, the engineering firm that designed it and the installation contractor.

    A variety of low-voltage electronic devices may fail to operate properly because of exposure to certain corrosive, gaseous environments. Susceptible items include consumer products such as microwave ovens, audio equipment, TV's and personal computers as well as many types of industrial sensors and automatic control devices. Failure generally occurs because of specific application factors. These include the severity of the environment, the presence or absence of atmospheric sealing of components within the device and the metals used at critical internal locations. Frequently complete failure doesn't occur but normal operation is erratic.

    A full size, cylindrical tank trailer pulled by a truck tractor/ cab split open on its lower section at mid-span and released hundreds of gallons of hydrochloric acid (HCl) onto a secondary highway in a northeastern state. When this occurred the truck driver jumped out of the truck's cab and sustained acid burns to his ankles because he was wearing low-quarter shoes.
