The engineer specified a VAV that is physically larger than the ceiling space provided. What are my redesign options

Plain-English answer

Document the clear spatial restrictions using a digital laser measure and photos. Bring the information to your foreman to submit an immediate RFI. * Potential approved engineering options include: 1. Shifting the VAV box location horizontally into an adjacent room corridor that features a higher decorative ceiling profile. 2. Requesting the engineer change the single large VAV asset specification out for two smaller, parallel dual-staged VAV boxes that can fit inside the narrow ceiling space footprint.

Field checklist

• Shifting the VAV box location horizontally into an adjacent room corridor that features a higher decorative ceiling profile.
• Requesting the engineer change the single large VAV asset specification out for two smaller, parallel dual-staged VAV boxes that can fit inside the narrow ceiling space footprint.
