Are Prefabricated Properties Natural Enough?

Unlike on the planet of human interactions, popularity is equated with quality on the planet of technology. The AEC industry is firmly supported by the technological advances of our age, and prefabricated housing is becoming increasingly popular. The emergence of prefabricated or modular construction in the housing industry is a reasonable and reliable solution to the process 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 form housing units prefabricated houses. Prefabricated housing may be independent dwelling units for individual families (houses) or single units that have been stacked on top of one another to form multi-storey housing or apartment blocks. How useful prefabrication is in the housing sector, why it is so and who will deliver services key to accurate prefabrication design are a number of the things we shall explore.

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 your website when they are prepared to be installed. A group 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 put together within the construction process or installed. Whole rooms, such as 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 floor in readiness for the newest home to arrive. Financing, construction and appraisals of these homes are carried out in the exact 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 your website, where these complete home units are connected floor by floor and then also connected to the location’s main water supply, sewage system and electrical lines.

How are they constructed?

They’re usually constructed in factories which are some distance away from the specific housing site, indeed they could be in an alternative 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 various components to the building. Beginning with floors, walls and ceilings, the structure moves along for internal fixtures and MEP elements such as piping, plumbing, boilers, bathrooms and entire kitchen fittings, before being moved across to finishing areas such as glazing, doors, electrical fittings and even bathroom tiling. Once your 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 connected to the city’s water and electrical connections and the prefabricated sections are sealed. Prefabricated homes may have a number of 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.

Through the settling-in time frame, a prefabricated home’settles’into the location, and 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 way of a set-up crew.

One of many driving forces behind a successfully assembled and reliably functioning prefabricated home is the potency of its design. Increasingly, architects, engineers, contractors and trade contractors use BIM (Building Information Modelling) construction drawings at some point within DfMA (Design for Manufacture and Assembly). DfMA is a style process that groups the style for manufacture, or the ease with which parts will undoubtedly be made for an item, with the style for assembly, which identifies the ease with which parts will undoubtedly 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 part of the 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 outsource the delivery of BIM services such as modelling and drafting. Outsourced firms specialise in delivering drawings and models quickly, using the latest software, such as 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 normally accurate and error-free.

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

Benefits of Prefabrication

  • Faster completion of projects, therefore reducing costs
  • Diverse uses – may be used to generate high-rises, single-storey construction, villas, townships, in addition to to generate 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 assisting to withstand earthquakes and other natural disasters. Concrete panels are created with aspects of top quality in a controlled factory environment and therefore last longer.
  • Suitable for certain sectors that have repetitive design elements, such as student housing, educational institutions, healthcare facilities, prisons, police stations and senior housing.
  • Increased and more effective 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 required to assembly components which have recently been assembled off site
  • Less waste is generated during construction, since prefabricated component waste is disposed of at the factory and not transported to your website
  • Competitive edge – allows flexibility in design decisions till the nth moment
  • Saves space – housing may be built-in 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 more options to pick from and builders have more build alternatives for construction, changing the entire construction landscape. Projects see MEP contractors use an increasing number 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 leading to improved insulation and better energy efficiency. This will ultimately benefit neighbourhoods and residential and commercial projects.

The various advantages of using prefabricated housing can only be enjoyed when the DfMA modelling and drawings are flawless. Because this demands considerable time and resources, an increasing number of Western firms are looking overseas for their prefabrication design services.

Benefits of Outsourcing Prefab Design Services

  • Cost reduction, since skilled labour and expenditure on resources overseas is significantly less expensive
  • Use of advanced tools and technologies, such as AutoCAD and Revit, by experienced and well-qualified human resources
  • Standardisation of drawings across projects, to ensure that MEP installations and other services are created easier
  • 3D axonometric drawings of the entire construction project are generated, showing methods and means by which individual subcontractor components or systems may be put 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 effective at working to constantly changing specifications, helping to complete projects on schedule
  • Increased flexibility, as outsourcing allows Western firms to select and choose services in accordance with need. The flexibility thus generated helps expand the business.

 

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