A vast range of modern methods of construction (MMC) techniques and products have been developed, drastically altering the construction industry’s behaviour from its previous state. This transformation is remarkable, and it is paving the door for even greater advancements in this field. What are Modern Construction Methods Modern construction methods (MMC) are methods established in the construction business with adequate planning and design to reduce construction time, cost, and overall sustainability for each project.Modern Building Techniques the current situation, there are numerous ways that are widely used and constructed. The most well-known and widely used modern construction methods are listed and discussed here.
Modern Methods of Construction
Flat Panel System Made of Precast Concrete This building process entails the fabrication of floor and wall units off-site. Separate manufacturing outlets and facilities are required for this. The panel units are then delivered to the job site and installed according to the design specifications and requirements. This strategy is best suited for operations that occur on a regular basis in a building project. Flat Panel System Made of Precast Concrete Precast Flat Panel System The prefabricated panels include services such as windows, doors, and finishes. This technology also incorporates factory-installed building envelope panels that include insulation and ornamental cladding and can be used as load-bearing elements. Volumetric Construction in 3DThe 3D volumetric building, as the name suggests, entails the creation of three-dimensional objects.
The modules can be transported using a variety of techniques and formats. This may entail transporting the basic construction or a completed unit with all interior and external finishes, as well as services installed within it, with only assembly remaining. The factory construction transports several units of the same product while retaining their quality. As a result, this technology is best suited for repetitive projects that require quick product assembly. Construction of a Flat Slab Flat slabs are structural elements with a wide range of applications. Because of its adaptability, it is often utilised in building. The flat slab allows for a shallower foundation and faster construction. Flexible column grids are also available in the system.
Flat Slab Construction
Flat slabs are a desirable choice wherever the partitions must be sealed to the slab soffit due to acoustic and fire considerations. When compared to other types of building, flat slabs are more efficient and cost-effective. The building of flat slabs can be completed with an excellent soffit surface quality, allowing exposed soffits to be used. Flat slab construction also helps to improve energy efficiency since it allows for the use of building thermal mass in the design of ventilation, heating, and cooling systems. Foundations made of precast concrete The precast concrete system can be used for quick foundation building. This strategy is better suited to a one-of-a-kind design.
The elements required for foundation construction are built separately at the factory (off site), then transported to the job site and assembled. The manufactured product must meet the designer’s quality specifications. Foundations made of precast concrete Precast Concrete Foundations Concrete piles support the majority of the foundation. Both systems are connected throughout the assembly process. These foundation technologies aid in increasing productivity, improving quality, and reducing the amount of soil excavated. This is best used in the face of harsh and unfavourable weather. When dealing with construction on a highly contaminated site, this technique of construction is the best option.
Dual Wall Technology
The twin wall technology is a hybrid wall system that combines the erection speed and structural integrity of precast concrete with the structural integrity of in-situ concrete. This type of wall system ensures the structure’s structural integrity and watertight reliability. Technology with Two Walls Twin Wall Technology As seen in , the twin wall system consists of two wall slabs that are separated. A cast in lattice girder separates the two slabs. The technique entails the following: The location is prepared for the installation of the wall components. The twin units are propped up for the time being. Later, reinforcing is used to connect the wall units. Concrete is used to fill the space between the wall pieces. This construction process is more efficient than traditional procedures.
Concrete Formwork Insulation Insulating concrete formwork (ICF) is a method that uses twin walled panels made of polystyrene panels or blocks. These are quickly constructed to serve as the building’s formwork. Concrete Formwork Insulation Insulating Concrete Formwork Concrete is poured into the formwork that has been constructed. This concrete is ready-mixed concrete that is manufactured in a facility with quality guarantee. Predominantly, ready-mix concrete is used.Expanded polystyrene blocks provide a higher level of thermal insulation. The concrete core will give increased durability and sound isolation. Panels of Precast Cladding The cladding system consists of layering one material over another to create a skin or covering. This layering system is better.
Precast Cladding Panels
The cladding does not provide any type of waterproofing. Instead, the cladding serves as a barrier against water entry. This safely aids in the direction of water or wind so that runoff can be controlled. This aids in the prevention of infiltration into the structure of the building.Concrete Floors and Walls Seat walls, retaining walls, aesthetic exterior, and interior finishes are all common uses for concrete walls.Concrete is also utilised as a floor covering. Concrete floors can now be finished to offer a smooth and appealing surface, thanks to advances in technology.Concrete floors give a wide selection of material for applications such as acid-stained paints, radiant floors, overlays, and micro toppers when compared to any other material. Concrete can be used as a flooring material.
MMC, according to the Joint Industry Working Group of the Ministry of Housing, Communities and Local Government, is a set of methodologies that includes off-site, near-site, and on-site pre-manufacturing, process improvements, and technology applications. The MHCLG’s MMC definition framework explains the seven types of MMC, allowing the full and future-proof range of “MMC” to be better understood through standard nomenclature.
The framework encompasses all forms of pre-manufacturing, as well as site-based materials and process innovation. Pre-manufacturing refers to operations carried out away from the final workforce, such as in distant factories, near-site or on-site “pop-up” factories, that use a produced led fabrication or consolidation process under controlled conditions prior to final assembly or installation. Category 7 includes on-site “workforce factories.”
Modern Methods of Construction
Modern methods of construction (MMC, or’smart construction’) have been advocated as a way of working more effectively to achieve more without using more since the Second World War and the pressing necessity to deliver new houses rapidly. It revolves around the employment of off-site construction methods that can take use of factory circumstances and mass manufacturing methods. The National Audit Office (NAO) published ‘Using modern methods of construction to build homes more swiftly and efficiently’ in November 2005, again in the midst of a housing crisis. It was commissioned by the Office of the Deputy Prime Minister and the Housing Corporation, and its goal was to figure out how to get the most bang for your buck when utilising MMC. It defined MMC as “…a procedure for producing more, higher-quality products.”
‘Modern methods of construction are about better products and processes,’ according to a similar report published in February 2006 by the Barker 33 Cross-Industry Group, which was formed to investigate why MMC adoption was low. They want to boost business efficiency, quality, customer satisfaction, environmental performance, long-term sustainability, and delivery time predictability. As a result, modern construction processes are more generally oriented than a narrow focus on product. They motivate people to seek improvements in construction delivery and performance by implementing improved processes.’
