PRODUCTION AND ASSEMBLY OF MODULAR HIGH RISE BUILDINGS ELISABETH LIVELY AND ALEXA SILVERMAN MODULAR CONSTRUCTION 60-90% of the structural components are built inside the factory, a highly controlled and safe environment Depending on what the customer wants, the module can be sent to the work site with complete exterior finishes, or just framing and insulation The majority of modules have mechanical, electrical and plumbing (MEP) Once the module is completely built, tests such as airtight tests and plumbing inspections are performed to ensure maximum quality and safety For taller buildings, such as high rises, the strategy implemented is a reinforced concrete or a steel-plated core that helps resist compression and provides more stability In order to transfer wind loads and provide an alternative load path, the modules are tied at their corners so that they act together as one strong unit ADVANTAGES The modules are usually transported by truck via highways and local roads. The average manufacturer will transport modules anywhere from 250-400 miles away from the factory Limiting factors of transportation include: obtaining oversized truck permits, crossing international borders, and following the size regulation of what oversized trucks may carry As the modules are being constructed in the factory, the staging area is prepared. The staging limits the amount of soil disturbed within the construction site and clearly identifies an area to store equipment and materials Once on site, the modules are stacked on top of each other and often around a structural core using a crane Being built in a factory increases the quality and consistency of the product, reduces the chances of unexpected complications, and allows for a more reliable and flexible schedule than traditional construction Waste from construction is reduced to less than 5% of the total material used in a factory compared to 10-15% in a traditional building site The prefabricated construction materials are easier to recycle, since they haven’t been exposed to the elements The number of visits to the on-site location made by delivery vehicles is reduced by up to 70% with modular construction, thus reducing the carbon footprint Modular construction can reduce the cost by 20 to 30% due to a shorter build time Modular construction can range from $90 to $150 per square ft., whereas conventional construction can cost from $150-$250 per square ft. The versatility of modular structures to be permanent or relocatable, in addition to the low prices and fast construction gives modular the opportunity to provide convenient and affordable housing Modular construction is the process of manufacturing modules in a factory-controlled environment, which are then transported to the construction site and assembled into a building. A module is essentially a complete room with interior and exterior amenities. The four main components of modular construction are design development, production of modules, transportation, and on-site assembly. Modular construction is a very well suited method of construction for high-rises due to its ease of production and assembly, structural integrity, and numerous other benefits. The table above shows the failure loads of C section wall studs and comparison with BS 5950-5. The effective bending stiffness of the bare steel sections is increased by up to 62% due to the attachment of oriented strand boards and cement particleboards on both sides. The figure above displays maximum permitted errors in manufacture of modules. When taking into account both the positional and geometric errors, the total vertical error (δ) can be defined as δ=e+nh/1000 mm, where e is the cumulative positional error, n is the number of stories, and h is the height of the module.
