• Pre-engineered metal buildings may have separate drawing packages — double-check spec coordination.
• Clean rooms and radiation-shielded enclosures require tight coordination with HVAC and electrical trades.
• Watch for vendor-furnished/contractor-installed language — common in this division.
• Special inspections and certifications are usually required for Division 13 scopes.
• Modular and prefabricated units often include shop drawings and performance testing sections.

1. What type of buildings are common in Division 13?
   Answer: Pre-engineered metal buildings, clean rooms, modular shelters, and more.
2. What should be checked when equipment is owner-furnished?
   Answer: Division 01 for installation responsibilities, handling, and delivery procedures.
3. What coordination is required for clean rooms or shielded spaces?
   Answer: HVAC, filtration, wall finishes, and possibly lead shielding or pressurization.
4. Why are certifications and special inspections important?
   Answer: Projects may require UL, seismic, or third-party inspections — delays can result if missed.
5. What makes modular installs unique?
   Answer: Factory-built structures may need rigging, warranties, power tie-ins, and close coordination.

Division 13: Special Construction

🔹 Key Teaching Points

1️⃣ Pre-Engineered Metal Buildings

• These systems often come with their own drawing package and engineering.
• Double-check that coordination exists between the base drawings and vendor submittals.

2️⃣ Clean Rooms & Shielded Spaces

• Clean rooms, radiation rooms, and special enclosures require HVAC/electrical coordination.
• Specs often call for pressure zones, filtration, and material separation.

3️⃣ Vendor-Furnished, Contractor-Installed

• Division 13 items are commonly purchased by the owner and installed by the contractor.
• Always check Division 01 for delivery and responsibility guidelines.

4️⃣ Special Inspections & Certifications

• Specs may require seismic anchoring, factory certifications, or third-party inspections.
• Missing these can hold up final approvals or occupancy.

5️⃣ Modular & Prefab Installations

• Includes prefab kiosks, shelters, and security booths — often with shop drawings required.
• Check for factory testing, warranty requirements, and power tie-ins.

✅ Wrap-Up Summary

• Division 13 covers specialized, pre-manufactured, or engineered systems.
• Coordination with trades and spec sections is critical for successful install.
• Don’t forget inspection and certification requirements — they’re often buried deep.
