  • BIM Standards for Project Records
    Last updated: Dec 2, 2020 BIM Standards for Project Records A. Overview 1. Intent The intention of this guide is to represent all the standards Xavier University has adopted for BIM. All architect and engineers developing BIM for XU should follow the standards within. XU has adopted BIM as a tool for project development as well as record documentation and facility management. Strict adherence to these standards will allow for the integration of BIM with Physical Plant facility management tools. 2. Building Information Modeling (BIM) BIM is a process involving the generation and management of digital representations of physical and functional characteristics of buildings. XU has adopted Revit as the primary tool for BIM generation. Revit files contain mass amounts of building data that can be integrated with other FM tools to support management of a building asset. At the initiation of a project, the University Project Manager will collaborate with the project A/E firms to establish a BIM execution plan with defined document deliverables. Project documentation required for assessment, review, bidding, construction, and as-built turnover is required to use Revit as the base model. Any exceptions to this rule require advanced approval by the XU project manager. 3. Getting Started Existing Buildings Revit current condition models exist for most of Xavier University’s buildings and site plans. Before developing a new model, consultants should request a building’s base file from the University Architect. New construction plans should be developed in this base model. For buildings that do not have an existing Revit base file, a new one should be created.

    40MB*C / 38MAQ Cassette Ductless Split System Sizes 09 to 18 Product Data INDUSTRY LEADING FEATURES / BENEFITS A PERFECT BALANCE BETWEEN BUDGET LIMITS, ENERGY SAVINGS AND COMFORT. The 38/40MB*C series ductless split systems are a matched combination of an outdoor condensing unit and an indoor fan coil unit connected only by refrigerant tubing and wires. The in- ceiling cassette fan coils are ideal for retrofit or modernization projects where a false ceiling is available. This selection of fan coils permits inexpensive and creative solutions to design problems such as: S Add- ons to current space (an office or family room addition) S Special space requirements S When changes in the load cannot be handled by the existing system. S When adding air conditioning to spaces that are heated by hydronic or electric heat and have no ductwork. S Historical renovations or any application where preserving the look of the original structure is essential. The ideal compliment to your ducted system when it is impractical or prohibitively expensive to use ductwork. These compact indoor fan coil units take up very little space in the room and do not obstruct windows. The fan coils are attractively styled to blend with most room decors. Advanced system components incorporate innovative technology to provide reliable cooling performance at low sound levels. LOW SOUND LEVELS BUILT- IN RELIABILITY When noise is a concern, the ductless split systems are the answer. Ductless split system indoor and outdoor units are designed to The indoor units are whisper quiet. There are no compressors provide years of trouble- free operation.

Through the use of variable speed components, the supplied capacity can be reduced to match the required load and hence reduce unnecessary energy consumption. However, for fan coil units, difficulties can arise when optimizing fan and pump speeds at part load.

  • Mechanical, Plumbing, and Fire Protection Conditions
    KJWW Draft Condition Assessment Report Mechanical, Plumbing, and Fire Protection Conditions Mechanical Conditions The mechanical systems within the building consist of a combination of the original 1926 systems and renovations that occurred in 1979. The majority of the existing mechanical systems are nearing the end of their useful life, and are in need of replacement. For the purpose of this report, the mechanical system reviewed were heating, ventilating and air conditioning (HVAC), plumbing, and fire protection. The major issues with the existing building are the lack of code required ventilation air and a fire protection system that is well below the current code requirement for this type of building. The following is a detailed review of each system and the current deficiencies within the building. Heating, Ventilation and Air Conditioning The heating system for the building consists of two gas-fired steam boilers located in the lower level mechanical room. One, ___MBH, boiler is original to the building and the other boiler, ___MBH, was installed during the 1979 renovation. Both boilers are currently operating, however, are nearing the end of their usable life. The chilled water system consist of one, ___ton, water-cooled chiller (CH-1) located in the mechanical room. There is also a heat reclaim chiller (CH-2), which rejects heat from the chilled water system to a hot water storage tank located in the same lower level mechanical room. Both chillers were installed during the 1979 renovation, and are nearing the end of their usable life. Figure * below shows significant rust and age degradation to the header of each chiller.

Many factors need to be considered before making the final decision about the heat- and/or cooling load, which terminal units to use, how to generate heating or cooling and a hundred other things. This application guide is developed to help you make some of these decisions by showing the consequences of certain choices. For example, it could be tempting to go for the lowest initial cost (CAPEX) but often there would be compromises on other factors, like the energy consumption or the Indoor Air Quality (IAQ).
