What is a PEMB?
"Pre-Engineered" is no longer an accurate term. All these buildings are "custom" engineered using automated design programs. The building is fabricated at the manufacturer's plant and assembled at the client's site. Metal building system manufacturers use computer tools to custom design each building system and all building components based on each customer's needs and specifications.
ParsCo is the preferred Southeast Region PEMB builder and is certified by Varco Pruden to perform the erection of these buildings. The Varco Pruden Building System is much more than just components. It is the complete building system including design, detailing, drawings, manufacture and warranty.
Based on local and national building codes, each metal building system is engineered to the required dimensions and designed to meet the loading conditions with the specified material. Once the building is designed and detailed, computerized instructions are sent to the fabrication plant where steel members are cut to exact standards. This precision custom manufacturing also reduces construction waste.
PEMB's are GREEN!
Made using metals, PEMB's have always been GREEN! Conventional buildings are constructed using bricks, sand and cement which results in environmental pollution. Steel buildings are environmentally friendly and can also help meet green initiatives. Up to 75 percent of steel used in metal buildings comes from recycled products and steel is 100 percent recyclable. Further, there is no requirement for any kind of welding process for construction, which helps save energy. These buildings are pre-drilled, pre-cut and pre-welded. The roofing systems are designed to meet LEED requirements for solar reflectance and heat emissivity.
PEMB's have longevity
Due to the permanence, durability, stability and quality of metal buildings, life cycles can reach up to 100 years. In addition, metal buildings are easy to insulate and, when paired with cool roofing, can help lower heating and cooling costs. Steel does not rot, warp, shrink or split and it is non-combustible. Any PEMB that by it's appearance is obviously a metal structure (such as a storage facility or airplane hanger) will come with a long lasting finish. For example they can be made from Galvalume or coated with Kynar which typically carries a 40 year warranty. Therefore even PEMB's with an exposed metal skin will not require maintenance such as painting.
Installation
As the design, engineering and fabrication of the new building is done at the manufactures facility, the pre fabricated components are shipped to the site for immediate erection. Typically this is performed by local crews certified and trained by the manufacturer.
Finishes
As noted earlier in this blog, these buildings are eminently suitable for any type of use and are offered with many exterior wall options, glazing and finishes including masonry, brick, ornamental metal or stucco facade.
ParsCo professionals take conceptual estimating services very serious. After all, the conceptual estimate could possibly be a deal killer when a developer is considering the hard costs on a new project.
The description of a conceptual estimates can range from a feasibility study, which carries ±20% margin of error with regard to the actual project cost, to a complex conceptual design estimate, which only carries a ±6% margin of error. Typically, conceptual estimates happen before a specific approach is decided for the project.
Conceptual estimating is part art and part science. The estimator has to have a "big picture" view, looking for long-range solutions rather than shortsighted projections. Conceptual estimators hone their craft with practice and experience, basing their estimates on real-world examples and past projects. According to the Design-Build Institute of America, Washington, D.C., a conceptual estimate is "the skill of forecasting accurate costs without significant graphic design information about a project." However, the lack of information does not negate the importance of a conceptual estimate, because it can make an appreciable difference in the cost effectiveness, feasibility, efficiency, and outcome of a project.
In developing a conceptual estimate, working with the developer can bring about the best possible outcome. But keep in mind that this approach may not necessarily be the least expensive. An estimator must look to the lifetime cost, which may include higher up-front costs but a lower lifetime cost of the building. You must also be aware that the best interest of the building owner may be at odds with the desires of the developer, who may want to get in and out of the building quickly with the least amount of cost.
For example, let's consider "green" building techniques. The use of photovoltaic panels, green roofs, geothermal wells, and other energy-efficient building materials still cost more than a conventionally built structure. However, the payback of reduced energy costs and reduced carbon footprint over the life of the building can outweigh the initial increased costs.
Research is always part and parcel of the conceptual estimating process, as there is no "outline" for this process. Each estimator must forge his own way and stretch the imagination to put his proposal into an interesting, understandable and usable format to move the project to the next level.
If you are considering a new project or development, contact ParsCo for expert conceptual estimating services. Our staff of skilled construction professionals can help you and your team determine the forecast of costs to build, analyze the preliminary design, and help steer the project to make it a reality. In the end, ParsCo can construct the project for the price as well.
