2.Steps to erect a pre-manufactured steel buildings

2.1 PREPARING THE FOUNDATION

The first and crucial step in erecting a pre-manufactured steel building is proper foundation preparation. A strong and stable foundation is key to ensuring structural integrity and longevity of the building.

This process begins with a thorough site survey to determine soil conditions and topography. This information is crucial for designing an appropriate foundation. After the survey is completed, the site must be cleared and leveled. Clearing involves removing vegetation, debris, and other materials that may interfere with construction.

Next, excavation is carried out according to design specifications. The depth and extent of excavation will depend on the type of foundation chosen, which can typically be shallow foundations such as slab-on-grade or deep foundations like pile foundations for more challenging soil conditions.

After excavation is complete, formwork installation and steel reinforcement are carried out. Formwork serves as a mold for the concrete, while steel reinforcement provides additional strength to the concrete structure. It’s important to ensure that the steel reinforcement is installed correctly and according to design specifications.

The next step is concrete pouring. Concrete must be mixed in the right proportions and carefully poured into the formwork. During this process, it’s important to ensure that the concrete is evenly distributed and no air pockets are trapped.

After the concrete is poured, the curing process begins. This involves maintaining concrete moisture for several days to ensure maximum strength is achieved. During this period, the foundation should be protected from extreme weather and heavy traffic.

Finally, after the concrete has reached the desired strength, anchor bolts are installed. These bolts will be the connection points between the concrete foundation and the steel structure, so their placement must be very precise according to the building design.

2.2 PRIMARY FRAMING

Once the foundation is ready, the next step is the installation of the building’s primary frame. This is the stage that determines the basic shape and structural integrity of the building.

The process begins with the delivery of pre-manufactured steel components to the site. It’s important to check all received components to ensure conformity with specifications and that no damage occurred during shipping.

Installation typically starts with the main columns. These columns are connected to the foundation through previously installed anchor bolts. The use of cranes or other lifting equipment is crucial at this stage to safely and accurately lift and place the heavy columns.

After the columns are in place, roof beams and connecting beams are installed. This creates the basic frame of the building. Connections between columns and beams typically use high-strength bolts or welding, depending on the building’s design and specifications.

Installing the bracing system is the next important step. This system provides lateral stability to the structure, helping to withstand wind and seismic loads. Braces are usually installed diagonally between columns and beams.

During this process, it’s very important to continually check the alignment and height of each component. The use of measuring tools such as theodolites or laser levels can help ensure installation accuracy.

After the main frame is installed, the next step is the installation of secondary frames such as roof and wall purlins. These components provide support for the roof and wall coverings.

Safety is the top priority during this stage. The use of appropriate personal protective equipment (PPE), such as helmets, safety shoes, and harnesses for work at height, is mandatory. Additionally, safe work procedures must be followed at all times, including proper use of lifting equipment and work platforms.

2.3 ROOF AND WALL SHEETING

The final stage in erecting a pre-manufactured steel building structure is the installation of the roof and walls. This stage not only provides protection against weather but also determines the external appearance of the building.

Roof installation usually begins with laying an underlayment or waterproof membrane over the roof purlins. This provides an additional layer of protection against water infiltration.

Next, the roof panels are installed. These panels are typically made of coated steel designed specifically for weather resistance. Installation starts from one end of the roof and moves to the other, ensuring proper overlap between panels to prevent leaks.

Special attention is given to the installation of flashings and trim. These components are installed at roof edges, joints, and other areas vulnerable to water infiltration. Proper installation is crucial to ensure the roof’s water tightness.

For walls, the process is similar. Wall panels are installed on the wall purlins, starting from the bottom and moving upwards. It’s important to ensure vertical and horizontal alignment of panels during installation.

Windows, doors, and other openings are installed according to the building design. Proper installation around these openings is crucial to prevent water infiltration and ensure energy efficiency.

Insulation is also an important component at this stage. Depending on the building’s needs, insulation can be installed in the roof and walls to improve energy efficiency and thermal comfort.

The final stage involves the installation of trim and other external finishes. This includes fascia, soffit, and other decorative elements that give the final touch to the building’s appearance.

Throughout the entire process, it’s important to continually pay attention to safety, especially when working at heights. The use of scaffolding, lifts, or safe work platforms is key to completing the work safely and efficiently.

3. Some mistake to avoid

3.1 FAILURE TO GET PRIOR APPROVAL

One of the most serious mistakes in pre-manufactured steel building erection projects is failing to obtain necessary approvals before starting construction. This is not just an administrative issue but can have significant legal and financial consequences.

Before starting the project, it’s important to understand and comply with all local regulations and requirements. This includes building permits, zoning approvals, and possibly environmental impact assessments. This process may take time, but it’s crucial to avoid delays or even mid-project shutdowns.

Moreover, failure to obtain proper approvals can result in fines, obligations to dismantle already built structures, or even legal action. This can severely damage the company’s reputation and cause substantial financial losses.

To avoid this problem, conduct thorough research on local requirements before starting the project. Consult with local authorities and, if necessary, get professional help to guide you through the permitting process. Ensure all required documents are complete and accurate before submitting them.

Remember that some approvals may take several weeks or even months to process. Therefore, start this process well before the planned construction start date. Also, make sure to keep copies of all approvals and permits on the project site during construction.

By taking these steps, you can avoid unnecessary delays, additional costs, and potential legal issues that may arise from failure to obtain necessary approvals.

3.2 UNPREPARED JOB SITE

Another common mistake in erecting pre-manufactured steel buildings is starting construction with an unprepared job site. Inadequate site preparation can lead to delays, increased costs, and even safety issues.

Proper site preparation involves several important aspects. First, ensure that the site has been cleared of all obstacles such as trees, large rocks, or old structures. Incomplete clearing can hinder the movement of heavy equipment and slow down the construction process.

Second, ensure that the ground contours align with the plan. This may require excavation, filling, or leveling. Uneven surfaces can cause problems in foundation installation and affect the overall alignment of the structure.

Third, ensure adequate access to the site for heavy vehicles and construction equipment. Narrow or unstable access roads can cause difficulties in material delivery and equipment movement.
