Revolutionizing Greenfield Projects with Prefabricated Structures

Focus image prefab

Manufacturers produce prefabricated structures, also referred to as prefab buildings, modular buildings, or pre-engineered buildings (PEBs), in a controlled factory environment to guarantee high quality and efficiency.

Unlike traditional methods, which involve on-site construction of central frames, PEBs simplify the process by designing and manufacturing steel components in the factory. These custom-built components are then easily erected on-site using nuts and bolts. Once limited to industrial buildings and warehouses, prefabricated structures are now finding their way into commercial buildings as well.

Components of Prefabricated  structures

Pre-engineered buildings (PEB) consist of structural and non-structural elements connected by bolted joints. Prefabricated structures consist of primary, secondary, sheeting, cladding, and accessories.

Components of prefabricated structure

Primary Components

Primary structure

The main framing system, comprised of robust steel frames, is the primary component of the building. This modular structure incorporates tapered rafters and columns, all produced at the manufacturing plant. Manufacturers customize the size and shape of these elements according to the application and specific requirements of the end-user.

Secondary Components

The secondary components in PEB are purlins and girts, eave struts, and bracings. 

  • Purlins and girts support the roof sheeting by running perpendicular to the rafters. Cold-formed C & Z purlins serve as secondary framing systems, connecting rafters and offering extra support. A bending press machine cold-rolls sheet metal strips, creating these components. The steel employed is of high strength, meeting ASTM A 570 standards or equivalent, with a yield strength of 345 MPa.
  • Eave struts are at the junction of wall cladding and roof sheeting.
  • Bracing is a diagonal element that gives the structure (lateral) stability.

Sheeting or cladding

Sheeting, or cladding,g forms the outer layer of the structure and shields the PEB from the elements.  

Accessories 

Accessories are additional components of the building. They can include insulation, vents, windows, and doors. 

Advantages of prefabricated structure

Speed and efficiency 

In construction, time is synonymous with money. Traditional methods face challenges such as weather delays, on-site inefficiencies, and unpredictable deliveries, causing potential delays. Prefabrication acts as a savior, being manufactured in controlled conditions away from nature’s unpredictability. 

According to a 2023 McKinsey & Company study, prefabrication can speed up end-to-end project timelines by 20 to 50% and concurrently cut costs by up to 20%.

Adv for PEB Structures

Cost-effective

Pre-engineered buildings (PEBs) offer a cost-effective choice for greenfield projects. Produced in a controlled environment, they minimize material wastage and boast quicker erection, slashing labour costs. The savings generated can be strategically reinvested in various project aspects. 

Prefabricated structures, in general, can yield a 20% cost reduction (source: Dodge Data & Analytics, 2020), making them an efficient and economical choice for construction projects.

Sustainable

The construction sector is a major polluter, primarily due to materials like cement and bricks, causing environmental and noise pollution. Traditional construction, conducted on-site, exacerbates these issues. In contrast, prefab and modular construction in controlled factory environments enhance sustainability by optimising material use, reducing waste, and encouraging recycling. 

Prefabrication’s positive environmental impact is especially evident in minimised site disturbance and noise pollution, making it ideal for urban or environmentally sensitive projects. It also champions energy efficiency through sustainable building practices and technologies.

Enhanced quality

Prefabricated structures prioritise quality assurance, eliminating variables such as on-site conditions and skill levels that might affect the final build’s precision. Shifting the manufacturing process to a controlled factory environment with advanced machinery, stringent quality control measures, and skilled craftsmanship ensures the precision and consistency of prefabricated components, meeting or exceeding industry standards. This commitment to quality not only enhances the durability of the builds but also instills confidence in stakeholders about the reliability of the construction method.

adv of prefabricated structures
  • Upfront investment: Initial costs can be higher, requiring careful planning and budgeting.
  • Specialised expertise: Transportation and assembly require specialised knowledge and partnerships.

How do you shortlist prefabricated manufacturers?

Define your project requirements

Streamline your prefabricated manufacturer selection by first outlining project specifics like size, complexity, budget, and sustainability goals. This initial step sets the groundwork for identifying compatible prefab partners.

Manufacture research

Identify firms with expertise in managing greenfield projects, adept at addressing their distinct challenges and opportunities. Verify their certifications, such as GRIHA (Green Rating for Integrated Habitat Assessment), IGBC (Indian Green Building Council), or ISO (International Organization for Standards), ensuring compliance with rigorous quality, safety, and sustainability standards.

Project references

To evaluate quality, reliability, and client satisfaction, ask for and carefully check references. Speak with previous customers and find out about their experience with the manufacturer; pay particular attention to things like timely delivery, communication, and build quality.

Asses site logistics expertise

There are special logistical challenges associated with greenfield projects. Verify the manufacturer has experience and tools to address transportation and erection challenges unique to your site.  This could be remote locations, challenging terrain, or poor infrastructure. Ask them how they will overcome these challenges and what their contingency plan is.

Establish open communication

Open communication is a must for the successful execution of any project but more so with prefabricated structures because they have off-site construction elements. Establish an open communication protocol from the beginning, including expectations, reporting guidelines, and dispute resolution, if any. Proactive communication and frequent updates promote confidence and avoid unpleasant shocks or delays.
