15 Things You Must Check Before Building a Shed

Don't Start Without A Plan

Building a shed without proper planning can cost you lakhs in mistakes.

In this guide, we’ll break down everything you need to know before starting. From site-level insights to structural traps, this 15-point checklist is your safety net against costly project failures.

The Ultimate 15-Point Pre-Construction Checklist

1. Soil Bearing Capacity (SBC)

Never start civil work without a soil test. If your soil is weak and you build a heavy foundation, the building might sink or tilt after a monsoon. Practical Tip: Most developers in Delhi NCR skip this and end up with cracked floors. Don't be one of them.

2. Wind Speed Analysis

Depending on your zone (Zone 1 to 5), your roof needs to handle a specific wind speed (e.g., 47m/s in some areas). A "cheap" roof is like a sail—it will fly away in the first major storm if the connections aren't designed for suction.

3. Structural Optimization

Are you using more steel than you need? Or worse, too little? A standard PEB design is optimized on software to ensure the perfect strength-to-weight ratio. This alone can save you 15% on material costs.

4. Roofing Grade & Coating

Not all Galvalume is the same. Check the GSM (grams per square meter) of the zinc-aluminum coating. AZ-150 is the gold standard for 20-year durability in India.

5. Fire Safety Clearance

Does your design allow for sprinkler pipes? If you realize this late, your racking height will be limited because of the low-hanging pipes. Check your clearances in the blueprint stage.

6. Ventilation (Turbo Vents)

A shed without ventilators is a furnace. Ensure at least one turbo ventilator for every 20-30 feet of roof length for natural convection.

7. Skylight Percentage

A simple hack: Use 4-6% of your roof as skylights. This provides free lighting during the day and significantly lowers your operational bills.

8. Flooring Type (FM2/VDF)

If you have high-reach forklifts, you need FM2 flooring (super flat). If it's a general go-down, VDF flooring with a slope is sufficient. Choosing the wrong one is a multi-lakh rupee mistake.

9. Eave Height vs. Hook Height

If you plan to install an EOT crane, your "Hook Height" is what matters, not just the "Eave Height". Always specify the Crane capacity during the design phase.

10. Contractor's Track Record

Visit at least one of their 5+ year-old projects. Do you see rust on the edges? Are the sheets leaking? A new shed always looks good; an old shed tells the truth.

11. Drainage Slope

Water pooling anywhere on the roof or near the foundation will lead to rust and structural decay within 3 years. Ensure a minimum 1:100 slope for all peripheral drains.

12. Raw Material Source

Ask for the "Mill Test Certificate" of the steel. Ensure the steel comes from reputable sources like JSW or TATA to guarantee the grade.

13. Welding Standards

Site welding is prone to errors and rust. Prefer factory-welded, bolt-on connections (PEB) wherever possible for uniform strength.

14. Electricity and Earthing

Ensure a proper lightning protection system (Lightning Arrester) if your shed is the tallest structure in the immediate vicinity.

15. Maintenance Accessibility

Design a safe walkway on the roof for maintenance. If men have to "walk on the sheets" to clean gutters, they might cause leaks or sustain injuries.

Comparing Quality vs. Cost

Insight from the Field

From our experience at Vyomn Projeccts... we've seen that the most expensive part of a shed is the "re-work". Fixing a leaking roof or a sinking floor after the building is operational costs 5x more than doing it right the first time.

Don't be scared by "Engineering" costs. A professional designer is your biggest insurance policy in industrial construction.
