Foam in the center … Both options have their unique benefits. The corner posts provide the compression resistance and are typically 100 x 100 SHS members. Module to-module connections are usually in the form of plates that are bolted on site. This results in a high-quality product that’s constructed in a safe, effective work environment. There are primarily two framing types used in modular construction. Mineral wool is generally used. Corridor zone can be used to provide in-plane bracing in long buildings. For example, Westchester Modular Homes builds a home’s rooms and … For example, homes built for final assembly in a hurricane-prone, earthquake or flooding area may include additional bracing to me… Manufacturers of light steel framed modules have prepared their own details of horizontal attachments that satisfy robustness requirements. Most importantly, modular buildings can be finished to match the design and facade of surrounding structures to seamlessly blend into your existing facility. Various cases are presented in the table for scheme design (based on wind loading in the Midlands of England). Technical delivery conditions. The rigid end frames are manufactured as part of the module or can be assembled as separate components. Design of Residential Buildings, SCI P272 Modular Construction using Light Steel Framing. Typical dimensions for planning in modular construction are presented in the table. Therefore, this mixed modular and panel form of construction is limited to buildings of 4 to 6 storey height. The compression resistance of the corner or internal posts controls the maximum height of the building, but 6 to 10 storeys can be achieved, as for fully modular construction. Module lengths depend on the overall building configuration, square footage requirements, and site layout, although they typically range from 30-72 feet long. Double skin walls provide excellent acoustic insulation. Difference Between Modular Building Types Modular Trailers. There are a variety of used modular buildings that are available for leasing. As modular construction has continued to grow in popularity and usefulness, the industry has rapidly improved its products. Cavity barriers are required within the cavity in the external wall between the module and the cladding at intersections with compartment walls. Containers. The load path is through the walls of the 3-D units, and so removal of this load path means that the walls should be designed to either: The latter means that the units should be tied both horizontally and vertically. A modular building is simply a property that has sectional modules that are prefabricated and can be configured to seamlessly join together to create a building that meets precise specifications. This will enable the parties to work together from inception to completion. The horizontal distribution of services between modules varies, depending on the building type. Overall stability is provided by the modules themselves, or by an external structure. Here’s a closer look at the timelines for both traditional and modular construction: The infographic below explains the main differences between the traditional and modular construction processes in more detail. Modular stairs may be designed as fully modular units and generally comprise landings and half landings with two flights of stairs. Means of escape should be considered early in the scheme design in order to ensure that the module design and layout can satisfy these requirements. Modules exceeding 4.3m width require additional speed restrictions and may require police escort. Guidance on the design and detailing of the most common connection types is given in BS EN 1993-1-8[5]. The depth of the podium type structure is 800 to 1000mm, and spans of 10 to 18m can be created below the podium, which are suitable for commercial applications and car parking. But the advantages do not stop there, so we are going to list all the benefits of a modular construction: 1. Two generic systems of facade construction may be considered: Cavity barriers must also be incorporated into any cavity that occurs between the external cladding and the modular structure. Structural insulated panels: A structural insulated panel is otherwise called SIP. Floors and ceilings in modular construction are deeper than in more traditional construction. Special lifting frames are used that allow the modules to be unhooked safely at height. Permanent Modular Construction. Only intend to use it temporarily? Use of modules with integral corridors can improve the speed of construction by avoiding weather tightness problems during installation and finishing work. Modular hospital building during installation of, Modular units used in multi storey social housing project in London, Layout of apartments using partially open sided modules – alternate modules are shaded, Primary steel frame used in a fully open sided module, Typical podium structure in which seven storeys of, Balcony attachments to external structure (MoHo, Manchester), Typical wall and floor/ceiling dimensions, Tying forces in modular construction subject to loss of one module by, Typical service duct in a modular hotel building, Compartment floor at junction with external wall and compartment wall, Typical trench-fill foundation detail for masonry cladding, BS EN 10346:2015 Continuously hot-dip coated steel flat products. Once all of the piles have been screwed in per plan, they are levelled off to laser precision. A welded fin plate to which the edge beams are bolted is shown. The edge beams may be connected to these posts by fin plates, which provide nominal bending resistance. In traditional construction, such activities are labour intensive on-site and are often on the critical path, so that any difficulties can cause delays. Wind loads can be transferred horizontally through the corridor floors. Two modules can be placed together to create wider spaces. External walls are detailed according to the type of cladding, but a 300mm total wall width may be adopted as a guide for most cladding materials. Stability provided by cross-flats or diaphragm action of boarding. The typical procurement process for modular buildings requires that the client, designer and manufacturer work together at all phases of the project to maximise the benefits of the off-site process and manufacturing efficiency. Two methods of specification by the architect are most commonly used: It should be recognised that each manufacturer undertakes the construction of their modular units differently and they will be prepared to offer advice and provide drawings at the concept stage. Each module is lined internally with one or two layers of fire resistant plasterboard as follows: In residential construction, each dwelling usually forms a separate fire compartment. Its purpose is to help individuals like you to discover how […], Modular building construction has grown in popularity over the last 40 years and serves a wide variety of industries. Ready to move/modular (RTM) homes refer to modular homes that are constructed on our site and moved fully completed to customer sites on a truck. Traditional, in which an architect provides the design co-ordination and the general contractor provides the construction co-ordination. The inherent separation between modules provides an effective barrier to spread of fire. An external steel structure, consisting of a façade structure that acts to stabilise the building, may also be used. Here are a few simple examples of how to calculate your modular building square footage based on the size and number of modules: As module construction is happening at the manufacturing facility, prep work is done at the building site. Balconies or other components can be attached to the corner or internal posts. However, you might still have questions or be unsure about whether modular is right for you. Access holes in the SHS allow bolts to be inserted through end plates to provide for vertical and horizontal attachments. Partially open ended module used in Barling Court, London(Image courtesy of PCKO Architects), Long module with an integral corridor(Image courtesy of Kingspan Off Site and Modular UK). The majority of modular construction work occurs off-site inside of a manufacturing facility. 4 sided modules can be designed with partially open sides by the introduction of corner and intermediate posts and by using a stiff continuous edge beam in the floor cassette. BSI, BS EN 1993-1-8:2005 Eurocode 3. For modular construction, it is appropriate to include whole life measures, such as potential re-use, or re-location which are not properly reflected in conventional measures of sustainability. For low rise buildings, in plane bracing or diaphragm action of the board materials within the modules provides shear resistance, assisted by the module to module connections, which transfer the applied wind forces to the group of modules. Permanent Modular Construction (PMC). The maximum width of opening is limited by the bending resistance and stiffness of the edge member in the floor cassette. The gap between the walls is a variable, depending on the number and thickness of boards and size of the wall studs. You’re in luck. Additional corner posts in the form of square hollow sections are often used. Permanent Modular Construction (PMC) Claddings for modular buildings can be self supporting vertically and only supported laterally by the units. Permanent modular buildings don’t have a limited lifespan and can last as long as traditional construction. In hotels and other residential buildings, each bedroom may form its own compartment. These buildings provide an alternative option to meet the broad, long-term space needs of businesses, schools, healthcare facilities, and more. The responsibility for design and coordination usually lies with the building designer. As open sided modules are only stable on their own for one or two storeys, additional vertical and horizontal bracing is usually introduced. Modular unit manufacturers use various methods to further improve sound reduction between units – two overlapping layers of plasterboard fixed inside each module, oriented strand board (OSB) or plasterboard fixed as external sheeting or quilt insulation between steel members. Details of 4 sided modules showing recessed corners with additional angle sections. This results in a high-quality, cohesive structure that will last for decades to come. Alternatively, non load bearing modules can be supported by a primary frame, and are installed as the construction proceeds. A type of prefab construction, the modular method ranges from manufacturing components such as panels and walls to full units such as kitchens and bathrooms in a factory … Internal walls comprising the walls of adjacent modules may be designed for a standard 300mm face face overall width, incorporating the sheathing boards, internal plasterboards and insulation between the C sections. Typically, modular dwellings are built to local, state or council code, resulting in dwellings from a given manufacturing facility having differing construction standards depending on the final destination of the modules. The flat slabs are structural elements that are highly versatile in … We recently released a podcast series called, “Built Modular”. Design of steel structures. Other types of cladding, such as clay tiles or metallic finishes, have their own dimensional requirements, but generally they can be designed and manufactured to fit with window dimensions etc. For most types of residential buildings and hotels, the corridor ceiling and floor voids act as service zones. 'Design and Build’ process, in which the module manufacturer provides the detailed design and construction responsibilities. transporting and assembling building elements for rapid site assembly to a greater degree of finish than in traditional piecemeal on-site construction The effect of transportation logistics on costs and module sizes. You’ve heard of modular construction, and you may have even considered using it for your business. Cladding that is completely or partially attached in the factory; infill pieces or secondary cladding may be fixed on-site. SHS provide the highest compressive resistance and may be used as the corner posts for open sided modules. Structural connections between modules are required for integrity and robustness but details vary depending on the form of the module and the particular application. A dimensional unit of 300mm may be adopted as standard for vertical and horizontal dimensions, reducing to 150mm as a second level for vertical dimensions. | Privacy Terms, What Is Modular Building Construction? This requires a high degree of accuracy in setting out service inlets on-site. The actual width will vary between 200mm for insulated render and board materials to 320mm for brickwork. The walls transfer vertical loads and therefore the longitudinal walls of the upper module are designed to sit on the walls of the module below. Vertical drainage stacks are also installed in the factory and a removable floor panel is provided to allow the final connection to the drains installed in the ground on-site. For this reason, fully open ended modules are not often used for buildings more than three storeys high. Pre-assembled buildings designed for permanent use can be multiple stories high. Design of joints. Placing the module in a recess in the floor of the main structure. The largest markets for modular construction are in student residences, military accommodation and hotels, but the health sector is significant as it requires highly complex services and medical installations that can be commissioned and tested off-site. The module design is similar to that described for 4 sided modules. Quality modular construction uses many different materials. This includes things like excavation, grading, foundation work, and utility installation. Comments on how modular construction contributes to these indicators are given against each indicator. Mineral wool may be required between the joists. A shallower parallel flange channel (PFC) section may be used to support the ceiling, but in all cases, the combined depth of the edge beams is greater than for 4 sided modules. The process and design method of modular construction … Modules can be set back from the façade line. Construction of walls and floors in modular units. Structural frame of a corner supported module – end view, Longitudinal edge beams of a corner supported module. A column spacing of 7.2m is suitable for below ground car parking. Modular structure construction uses an inside-out approach to manufacturing a building. The supporting structure is designed conventionally as a steel framework with beams and columns that align with multiples of the module width, and provides open plan space at ground floor and below ground levels. The length of the module may be limited by transport and site access but a length of up to 12m is normally practical. Check out this video for an inside look at the modular manufacturing process: Businesses and organizations in a variety of industries choose modular construction for their projects. To date, the main types of MMC that have been used are steel/concrete frameworks & pods, concrete panellised … Everything You Need to Know, Steel and concrete (Type II-B non-combustible) construction, Drywall or VCG (vinyl-covered gypsum) interior wall finish, Acoustical ceiling (also known as drop ceiling), Carpeting (rolled carpet or carpet tiles), VCT (vinyl composite tiles) or ceramic tiles. Insulation in the line of the roof pitch is used where a ‘warm roof’ is created. What is Modular Construction? In this case, the client’s architect may carry out some of the outline design, and may be novated by the client to work for the contractor. For corner supported modules, a standard overall floor and ceiling depth of 600mm may be used. Various interfaces between modular units and other components in the building may not be under the control of the modular manufacturer. The framework of the module is often in the form of hot rolled steel members, such as Square Hollow Section (SHS) columns and Parallel Flange Channel (PFC) edge beams, that are bolted together. Contrary to popular belief, modular buildings can be both functional and attractive. A variety of foundations can be used, including strip, trench-fill, pad and piled foundations. Because modular construction takes place simultaneously in a factory and on-site, it can be completed in half the time of traditional construction. Modular construction is actually the most complete type of prefab construction. Strip or trench-fill foundations are most common. Modular construction is the process where buildings are made up of individual sections, constructed in an off-site controlled manufacturing facility, and assembled together at the final building site. Home construction projects can be completed 30-50% faster than using traditional construction methods. Nevertheless, the cladding options and building height may dictate the foundation design. End plates and Hollo-bolts to the SHS members may also be used. The landings and half landings are supported by longitudinal walls with additional angles or SHS members to provide local strengthening, if necessary. Temporary modular buildings typically have a useful life of 20-25 years, but this can be extended if they are well-maintained and periodically renovated. The services in each module are installed in the factory and terminate in the vertical duct. However, in most cases, the roof space is ‘cold’, and insulation is placed directly on the upper surface of the modular units. This solution … However, there are a variety of permanent modular construction (PMC) choices available. Don’t want to own your modular building for business purposes? The open top and base of the wall may be strengthened by a T, L or similar members to transfer out of plane loads to the landing. The decision-making process for modular construction differs from more traditional methods of construction because of: Since the benefits of modular construction are realised through pre-fabrication, the initial design phase, including the space planning and subsequent detailed design, service integration, and co-ordination, are critical. All modular buildings — temporary or permanent — can be expanded, remodeled, and updated whenever necessary. With strips, rafts or ground beams, the modular units can be designed to be continuously supported around the perimeter of each unit. Temporary modular buildings are commonly located at construction sites or expanding businesses. Your Ultimate Guide. Modules using hot rolled steel framework can be designed to support concrete floors for use in medical and other applications, where strict control of vibrations is required. The sustainability indicators relevant to modular construction are listed below. What is Modular Construction? Modular units are lightweight and therefore foundations may be smaller than in traditional construction. It is typically used in residential buildings, particularly of terraced form, comprising modular ‘cores’ for stairs, and highly serviced areas. Because they’re built in sections, modular buildings even undergo structural inspections throughout the construction process. Modular buildings are engineered and fabricated to meet the same building codes as traditionally-built structures. However, although these sections are compact, their connections can be more complex. In such cases, the role of the client’s architect will depend on the particular procurement process. Traditional construction projects require that all work be completed on-site and from the ground up. The need to make key decisions early in the procurement process, The important environmental and site-related benefits that can be achieved. Roofs are generally designed as separate structures that are supported either continuously by the internal walls of the modular units, or as free spanning roofs between the outer walls. Floors. Modular construction is a form of off-site construction in which a building’s components, or modules, are constructed in a factory setting before being transported to site for assembly. In some cases, the roof can be designed to be detachable so that the building can be extended later. In this case, the supporting columns are positioned at a multiple of the width of the modules (normally 2 or 3 modules). The concept of using sustainability indicators is becoming accepted as part of the environmental assessment of building construction. As such, it’s easy to understand why people perceive modular as only a temporary solution. Service strategies that have been used in modular buildings include: A vertical service duct is usually incorporated in the corner of each unit to accommodate the vertical drainage and pipework. Floors of modules comprise C sections of 150 to 250 mm … The cellular space provided is limited by the transportation and installation requirements. Standard container vehicles can deliver one large or two smaller units. It comes in several forms – the principal focus of this article is volumetric modular systems. For buildings of 6 to 10 storeys height, a vertical bracing system is often located around an access core, and assisted by horizontal bracing in the corridor floor between the modules. Course details Modular construction is a collection of practices and techniques for constructing buildings offsite. Flat roofs can also be constructed with a variety of weatherproof finishes. Guidance on transportation on major roads is given by the Road Haulage Association, based on the Road Vehicles (Construction and Use) Regulations[2]. An example of the mixed use of modules and primary steel frame is shown below left. Ultimately, modular prioritizes efficiency, durability, and quality control. The modules are constructed in a similar way to that described for open-sided modules, but the loading applied to the side of the modules is significantly higher. The architect may specify the manufacturer who will undertake the detailed design work. Modular construction methods involve individual sections (called modules) that are constructed in a controlled, off-site manufacturing facility and assembled at a building site. Overall stability is provided by additional bracing located in the walls of the modules. The close involvement of the client in assessing the business-related benefits provided by the method of construction. The podium structure is generally braced to resist wind loads and a separate braced core is often used to stabilise the group of modules above the podium level. Compatibility of the floor depth in the module and in the floor elsewhere is achieved by one of four methods: Balconies may be attached to modules in various ways: Atria may be created by attaching a lightweight steel roof to the upper modules or by by spanning the roof between the modules as shown.
