Building a Durable PV Shed Warehouse: A Step-by-Step Guide
This article will guide you through the key steps involved in constructing a PV shed warehouse. By following these steps and ensuring proper coordination, you can ensure a smooth and efficient building process.
Planning and Design:
- Involve the Right Professionals: It's crucial to involve a qualified architect or civil engineer (thekedar) and an experienced fabricator (welder) for the design and construction of your PV shed. Their expertise will be essential for a strong and functional structure.
- Collaborative Design: Ensure clear communication and coordination between the architect/thekedar and the fabricator. This will allow them to work simultaneously on their respective tasks, saving you time and resources.

Construction Stages:
1. Civil Work:
- Column Construction: Begin by building the main support structure – the columns. These will be constructed using iron bars (saria) and concrete mixture. The size of the bars (e.g., 1.5” or 1”) will depend on the shed's area and height. The thekedar will advise on the appropriate sizing for your specific needs.
2. Steel Structure Fabrication:
- Concurrent Work: While the civil work is ongoing, the fabricator can start planning and measuring for the steel structure. This includes measuring the columns and positioning the iron channels on top. This simultaneous work requires the presence of both the civil engineer and the fabricator for smooth coordination.

3. Wall Construction and Rainwater Management:
- Wall Options: Once the columns are complete, the civil engineer will focus on building the walls. You can choose either bricks or AAC blocks for this purpose.
- Steel Sheeting Installation: Meanwhile, the fabricator will continue with the construction of the shed's roof and sidewalls using iron pipes and channels.
4. Rainwater Management System:
- Water Gutters (Patnalla): Install water gutters along two sides of the shed to collect and direct rainwater flow.
- Drainage Chambers: Consider your warehouse size. For smaller warehouses (less than 10,000 sq ft), water gutters alone may suffice. However, for larger areas (greater than 10,000 sq ft), we recommend installing underground chambers (approximately 4 ft x 3 ft x 5 ft) at specific intervals (around 20 ft apart, depending on the area). These chambers will collect and channel rainwater away from the building foundation, preventing leaks and blockages.

5. Floor Construction:
- Debris and Sand Base: After the civil work is complete, the thekedar will oversee the preparation of the warehouse floor. This involves filling the area with debris (malba) to a designated height, followed by spreading and leveling sand over the entire floor area (up to 1-2 feet deep).
- Compaction and Smoothing: Water is then poured onto the sand surface over several days to allow for proper settling and hardening. Subsequently, a roller machine is used to compact and smooth the sand base.
- Stone Layer and Additional Compaction: Once the sand is compacted, a layer of hard stones (2-3 inches in size) is spread across the floor. This layer is then compacted again using the roller machine.
- Steel Rebar and Concrete Floor: Steel/iron rebars are then tied over the entire surface, creating a strong foundation for the concrete floor. The concrete floor is poured in sections using a cement, crusher, and stone mixture.
- Floor Hardening and Finishing: After each section sets (approximately 5-6 hours), a hardener is spread, followed by a finishing layer using a screed machine for smoothness and additional hardening. The floor is then watered for a few days to ensure proper curing.
- Grouting: Once the floor is completely cured, grouting is performed to minimize cracks and gaps in the surface.

6. Floor Polishing (Optional):
Although not strictly necessary, floor polishing offers significant benefits. It enhances the floor's shine, smoothness, and durability, preventing cracks and wear over time.
- Conclusion
- Building a PV shed warehouse requires careful planning and coordination between different specialists. By following these steps and working with qualified professionals, you can ensure a successful and efficient construction project. Remember, consulting with your architect/thekedar and fabricator throughout the process will lead to a high-quality and functional PV shed that meets your specific needs.
