How Popular Is Prefabricated Housing?

Unlike in the world of human interactions, popularity is equated with quality in the world of technology. The AEC industry is firmly supported by the technological advances of our age, and prefabricated housing has become increasingly popular. The emergence of prefabricated or modular construction in the housing industry is a reasonable and reliable treatment for the challenge of quality housing worldwide. Prefabricated housing, sometimes called prefab homes, prefabs or modular homes, are made off site in sections, from just bathrooms to entire floors, that can be transported, placed or assembled to create housing units. Prefabricated housing may be independent dwelling units for individual families (houses) or single units that have been stacked together with one another to create multi-storey housing or apartment blocks. How useful prefabrication is in the housing sector, why it is so and who is able to deliver services key to accurate prefabrication design are a few of the things we will explore shipping container.

So, what’re prefabricated buildings?

Prefab buildings may be built from components (such as panels), modules (in the case of entire modular homes, houses on wheels) or sections (parts of manufactured homes) constructed off site and utilized in the site when they are ready to be installed. A team of technical experts attach different services to the building layout. These can include double-storey homes and customised homes. Modular or prefabricated homes may be created in sections and then transported on site to be come up with included in the construction process or installed. Whole rooms, such as for example bathroom pods or kitchens, may be created in a factory setting as prefabricated units. Steel frames may be erected on site to’slot’in the prefabricated units or entire concrete foundations may be laid into the ground in readiness for the new home to arrive. Financing, construction and appraisals of those homes are carried out in the same way in terms of regular homes. Prefabricated houses can also be assembled on production assembly lines, which are transferred in complete sections or floors to the site, where these complete home units are connected floor by floor and then also linked to the location’s main water supply, sewage system and electrical lines.

How are they constructed?

They’re usually constructed in factories that are some distance far from the particular housing site, indeed they are often in a different country. These purpose-designed factories effectively contain assembly line environments, where different elements and trades bond at different stages of the assembly line to incorporate the many components to the building. Starting with floors, walls and ceilings, the structure moves along for internal fixtures and MEP elements such as for example piping, plumbing, boilers, bathrooms and entire kitchen fittings, before being moved across to finishing areas such as for example glazing, doors, electrical fittings and even bathroom tiling. Once the house is assembled, it passes through final QA checks before being handed over to logistics teams for transport to its permanent site.

Plumbing and electrical lines are linked to the city’s water and electrical connections and the prefabricated sections are sealed. Prefabricated homes may have several rooms and be of different designs. These homes may be set on a permanent foundation, blending in seamlessly with other regularly constructed homes. Repairs on the homes are conducted by the real estate company associated with its sale.

During the settling-in time period, a prefabricated home’settles’in to the location, after which it some cracking of the drywall could occur. Appliances which were incorrectly installed may be repaired by changing the wiring or plumbing, and the ventilation, heating, cooling, plumbing and electrical systems may be properly installed by a set-up crew.

One of many driving forces behind a successfully assembled and reliably functioning prefabricated home is the effectiveness of its design. Increasingly, architects, engineers, contractors and trade contractors use BIM (Building Information Modelling) construction drawings at some point included in DfMA (Design for Manufacture and Assembly). DfMA is a style process that groups the style for manufacture, or the ease with which parts will soon be made for an item, with the style for assembly, which describes the ease with which parts will soon be assembled. DfMA helps the style team reduce manufacturing and assembly costs by identifying, analysing and removing waste and inefficiency from the product’s design. DfMA modelling and drawing is fast becoming synonymous with design for prefabrication.

Construction drawings, or shop drawings, graphically illustrate the important points, data and specifications of a prefabricated design, contain information regarding the MEP (M&E) systems and include the important points of prefabricated components. BIM technology is the main larger virtual design and construction (VDC) process that helps find answers to challenges faced by subcontractors and designers before building prefabricated components in the factory.

Advances in technology have made it possible and indeed better than outsource the delivery of BIM services such as for example modelling and drafting. Outsourced firms specialise in delivering drawings and models quickly, using the latest software, such as for example Autodesk 3ds Max, Autodesk Revit, Autodesk Navisworks and others, and by employing well-qualified experts. Modular construction drawings supplied by these CAD drafting firms are generally accurate and error-free.

Prefabricated construction has reportedly been utilized in the world’s tallest building, the Burj Khalifa, in Dubai and in the construction of the prestigious Sydney Opera House.

Features of Prefabrication

  • Faster completion of projects, therefore reducing costs
  • Diverse uses – can be utilized to create high-rises, single-storey construction, villas, townships, as well as to create ceiling slabs, terrace blocks, wall panels, columns, staircases, bathrooms, light fixtures, etc.
  • Customisation – unique property specifications may be accommodated easily, resulting in reduced expenses
  • Durability – prefabrication in the structural aspect of construction bolsters structural strength, sometimes helping withstand earthquakes and other natural disasters. Concrete panels are manufactured with aspects of high quality in a controlled factory environment and therefore last longer.
  • Suitable for certain sectors that have repetitive design elements, such as for example student housing, educational institutions, healthcare facilities, prisons, police stations and senior housing.
  • Increased and better quality control in factory settings
  • Safer and less stressful working environment for labourers in a factory than on site, especially in crowded areas, as on-site dangers are eliminated for workers
  • Less on-site space is needed to assembly components which may have been already assembled off site
  • Less waste is generated during construction, since prefabricated component waste is discarded at the factory and not transported to the site
  • Competitive edge – allows flexibility in design decisions till the nth moment
  • Saves space – housing may be integrated cramped spaces in tight schedules and occupy less space


Modular construction in the housing industry has expanded its scope for buyers and builders. Buyers have significantly more options to pick from and builders have significantly more build alternatives for construction, changing the general construction landscape. Projects see MEP contractors use an increasing quantity of modular construction plans during collaboration. Prefabricated construction is less expensive and more green, since such buildings are better sealed against drafts and there is improved quality control systems in factories, thus ultimately causing improved insulation and better energy efficiency. This can ultimately benefit neighbourhoods and residential and commercial projects.

The different benefits of using prefabricated housing can just only be enjoyed once the DfMA modelling and drawings are flawless. Because this demands considerable time and resources, an increasing quantity of Western firms are looking overseas because of their prefabrication design services.

Great things about Outsourcing Prefab Design Services

  • Cost reduction, since skilled labour and expenditure on resources overseas is considerably less expensive
  • Utilization of advanced tools and technologies, such as for example AutoCAD and Revit, by experienced and well-qualified human resources
  • Standardisation of drawings across projects, to ensure that MEP installations and other services are made easier
  • 3D axonometric drawings of the whole construction project are generated, showing methods and means where individual subcontractor components or systems may be placed in the project
  • Skilled draftsmen and other technical professionals work faster, maintain accuracy, provide complete audit trails with drawing references, approval records
  • Faster turnaround time, since overseas firms employ ready and dedicated teams of trained personnel capable of trying to constantly changing specifications, helping to perform projects on schedule
  • Increased flexibility, as outsourcing allows Western firms to select and choose services based on need. The flexibleness thus generated helps expand the business.


Outsourcing prefabrication design services is thus an increasingly popular option, and this method will save time, increase productivity, ensure higher safety levels and increase profits. Using Revit, AutoCAD and other software to create modular construction drawings and models helps provide high-quality prefabricated design support for Western firms in the industry.
