types of modular construction methods

Stability provided by cross-flats or diaphragm action of boarding. 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. Typical dimensions for planning in modular construction are presented in the table. There are a variety of used modular buildings that are available for leasing. The interface between the roof and the modular units is designed to resist both compression and tension due to wind uplift. They are used as toilet/bathroom units, plant rooms or other serviced units and are supported directly on a floor or by a separate structure. The landings and half landings are supported by longitudinal walls with additional angles or SHS members to provide local strengthening, if necessary. The main sectors of application of modular construction are: Thousands of modules are manufactured annually in the UK. An example of the mixed use of modules and primary steel frame is shown below left. Guidance on the design and detailing of the most common connection types is given in BS EN 1993-1-8[5]. 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. These industries include (but are not limited to): Modular construction methods are often compared to building with blocks, because each building section is constructed to fit perfectly with the next one. Permanent Modular Construction (PMC) Here are just a few of your options for customizing the appearance and operations of your modular building: Just like any building, the life expectancy of a modular building depends on whether it receives regular maintenance. The horizontal distribution of services between modules varies, depending on the building type. Wind loads can be transferred horizontally through the corridor floors. This will enable the parties to work together from inception to completion. Special care needs to be taken around openings for service pipes or other penetrations, because sound attenuation is particularly affected by air pathways between spaces. These buildings provide an alternative option to meet the broad, long-term space needs of businesses, schools, healthcare facilities, and more. 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. A steel external framework comprising walkways or balconies may be also designed to provide stability. Modules are manufactured from a series of 2D panels, beginning with the floor cassette, to which the four wall panels and ceiling panel are attached generally by screws. 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. These modular homes are intended … Plus, they’re more affordable than new buildings. Balconies or other components can be attached to the corner or internal posts. This results in a high-quality product that’s constructed in a safe, effective work environment. 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. However, many common modular building myths remain. Your Ultimate Guide. Structural insulated panels: A structural insulated panel is otherwise called SIP. Modules can be manufactured with integral balconies and a range of cladding materials can be pre attached or installed on site. Inspections are also performed at the project site during assembly to further verify the building’s structural integrity. Technical delivery conditions. Nevertheless, the cladding options and building height may dictate the foundation design. Traditional, in which an architect provides the design co-ordination and the general contractor provides the construction co-ordination. 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. ‘Hybrid’ modular and panel building showing planar floors and walls attached to the modules, Load-bearing bathroom modules were used to support the floor cassettes at Lillie Road, Fulham(Image courtesy of Feilden Clegg Bradley). What is Modular Construction? Fire stops must be provided around any penetrations through fire resisting walls. Because they’re built in sections, modular buildings even undergo structural inspections throughout the construction process. In this course, you can learn about the different types of modular construction, understand their limitations and advantages, and learn how to manage the modular construction … 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. In such cases, the role of the client’s architect will depend on the particular procurement process. Long modules can also be designed to include an integral corridor, as shown below. People are most familiar with this type of construction in the use of bathroom pods, which is a common method of construction … All Rights Reserved. Permanent modular construction is a sustainable building method, which uses lean... Relocatable Buildings. The concept of using sustainability indicators is becoming accepted as part of the environmental assessment of building construction. Claddings for modular buildings can be self supporting vertically and only supported laterally by the units. 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. 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. End plates and Hollo-bolts to the SHS members may also be used. Modern roofs may comprise tiles supported on roof sheeting or structural liner trays. 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. For example, Westchester Modular Homes builds a home’s rooms and … The module manufacturer acts as a specialist sub-contractor.
