Price of Fireproof Installation of Vertical Shaft Cable Trays

The cost of fireproof installation for vertical shaft cable trays typically ranges from $50 to $150 per linear foot, depending on materials, fireproofing method, and labor complexity.

Factors Affecting Cost

1. Fireproofing Materials:

• Common materials include firestop packs, fire-resistant mineral wool, fire-rated boards, firestop mastic, and specialized coatings or tapes such as FLAMMOTECT-A or DG-CR 0.7 .
• Material choice affects both performance and cost. Mineral wool and firestop packs are generally more economical, while high-performance coatings for critical facilities (e.g., hospitals, nuclear plants) are more expensive. 2. Cable Tray Type and Material:
• Vertical shaft trays are often painted steel, galvanized steel, or stainless steel for indoor and outdoor use .
• Corrosive or high-humidity environments may require aluminum or fiberglass-reinforced trays, which increase material costs. 3. Labor and Installation Complexity:
• Installation requires precise alignment, plumb mounting, and sealing of all gaps to meet fire safety standards .
• Labor costs rise with shaft height, number of penetrations, and accessibility. Firestopping in vertical shafts is more labor-intensive than horizontal runs due to scaffolding or lift requirements. 4. Compliance and Testing:
• Fireproof installations must comply with local fire codes and standards (e.g., BS EN 61537 for cable trays, firestopping standards for wall/slab penetrations), .
• Additional costs may include inspection, certification, and testing to ensure fire resistance ratings are met.

Typical Pricing Range

• Standard commercial installations: $50–$80 per linear foot.
• High-performance or critical facilities: $100–$150 per linear foot.
• Additional costs: Scaffold rental, shaft access, and complex penetrations can add 10–30% to the base cost.

Recommendations

• Obtain multiple quotes from certified fireproofing contractors.
• Specify fire rating requirements (e.g., 1-hour, 2-hour) and shaft dimensions to get accurate pricing.
• Consider pre-fabricated firestop systems for faster installation and consistent quality. By accounting for materials, labor, and compliance requirements, you can estimate the total cost for vertical shaft cable tray fireproofing and plan your budget accordingly .
