<强>使用环氧涂料和环氧涂层结构衬垫可以节省时间和金钱上的传统管的修理方法。
损坏或恶化的管道系统可能是昂贵的更换，特别是那些位于难以到达的位置或不拆除选择性不可访问。幸运的是，常见的管道系统可以从内使用固化就地环氧涂料或环氧涂层结构衬垫平反，。相比传统的管线修复方法时，这些原位管修复技术可提供高达30％的储蓄高达60％和时间的节约成本。We’ve partnered with Nu Flow to highlight several different in situ pipe repair techniques available to facility managers and building owners.

二氧化碳(CO2)是人类呼吸作用的副产物。每当我们呼气时，CO2 被释放到我们周围的大气中。 Currently, CO2 sensors can be used to automatically control ventilation systems in buildings equipped with Building Automation Systems (BAS). This is referred to as Demand Control Ventilation (DCV).

The City of Takoma Park, Maryland, needed to replace a failing retaining wall that supports a roadway in a small residential development. The Linden Avenue site is directly adjacent to Sligo Creek, which is a tributary of Anacostia Creek, a river undergoing a significant restoration effort. T. E. Scott & Associates, Inc., designed a replacement for the failing retaining wall infrastructure, created a pocket park for the local residents, and provided water quality treatment for the unmanaged watershed. This combination of aesthetic and environmental improvements adds value to the project. We’ll look at some stormwater flow design calculations, a storm water flow splitter, an urban modular wetland unit, a step/plunge pool, and an interesting retaining wall design. Located in Freeport, Pennsylvania, about a 30 minute drive north of Pittsburgh, Buffalo Township’s water treatment plant produces over 700,000 gallons of fresh water daily. The plant provides drinking water to over 5,000 residents in Buffalo Township and Freeport Borough. It is also the fresh water supplier for the Municipal Authority of South Buffalo Township. Join Buildipedia for a photo tour of Buffalo Township’s water treatment plant, as we trace the flow of water from the Allegheny River to its distribution throughout the utility. Buffalo Township’s wastewater treatment plant is located along Buffalo Creek in Pennsylvania, beneath the State Route 28 bridge. This type of wastewater treatment plant is perfect to serve smaller communities. It supports 6,000 people with 3,100 sewer connections to homes and businesses throughout Sarver, Pennsylvania, and the vicinity. It’s an excellent example of an efficient wastewater infrastructure that uses extended aeration to treat raw sewage, without any initial sedimentation.
Information on low-flow plumbing fixtures abounds, and low-flow and waterless urinals are now in widespread use. Flush volume for toilets has evolved to 1.6 gallons per flush, or less than half of the 1980s' standard of 3.5 gallons. The fact that low-flow fixtures can save money in utility costs is clear and easy to calculate with a review of a water bill and an estimate of each fixture’s cycles per month. An enticing payback period for a new fixture purchase can be calculated based on water use alone. However, some facility managers argue that the utility savings offered by these plumbing fixtures are not matched by the unforeseen maintenance and repair costs that they generate. The question of whether low-flow plumbing fixtures offer a good return on investment (ROI) arises.
Michel Theriault understands the working environment that facility managers face daily – the technical challenges and opportunities within their facility management organizations and additionally the relationships and business dynamic beyond the facilities management staff. Many facility management resources offer the latest technical insights and maintenance strategies, but Theriault’s book takes on facilities management business aspects not often addressed in this field. Managing Facilities & Real Estate clearly stands out in this regard. It offers rare and valuable business advice for facility managers using practical and easy-to-read terminology and graphics.
A challenge of mining operations and any project that disturbs large volumes of earth below grade is the potential to generate contaminated water runoff at the surface known as acid mine drainage (AMD). Precious metal and coal mine shafts traditionally require excavation below the water table, exposing metal sulfides in the disturbed earth and waste soils to the atmosphere and water. Similar exposure can occur during major highway construction projects. Stormwater runoff and water discharged from dewatering pumps related to these construction activities can be very low in pH (acidic) and can contain harmful metal ions. Eric McCleary of Greenhorne & O’Mara helped develop the successive alkalinity-producing system (SAPS) process to treat this AMD water and shares insights regarding this innovative technology with the Buildipedia audience.
Originally developed as a checklist to be used during development and execution of Engineering, Procurement, and Construction contracts (EPC’s), Mike McMahon’s EPC Checklist has broad application -- whether you are developing project punch list items, ensuring separate tasks are scheduled by engineers, vendors, contractors and project managers, or providing construction inspectors a list of work items to validate in the field, this comprehensive list of questions will add value to your project. Sometimes construction project solutions and positive outcomes are all about knowing the right questions to ask -- here are 10,500 of them, organized by 176 subjects of construction work type.
