IFC Project Planning & Scheduling 3 — Questions and Answers
Question 1: A firestop scope-of-work change is verbally approved by the GC superintendent. What should the installer do?
- Proceed immediately to avoid schedule delays
- Refuse to proceed until a written change order is issued (Correct answer)
- Document the verbal approval in the daily log only
- Ask another subcontractor to complete the changed scope
Correct answer: Refuse to proceed until a written change order is issued
Verbal approvals are not contractually binding; a written change order must be issued before performing out-of-scope work.
Question 2: What scheduling impact does a fire-rated assembly's required cure time typically have on a project?
- None, since firestop materials are rated upon application
- It adds a mandatory hold period before the area can be closed or reoccupied (Correct answer)
- It only affects exterior applications
- Cure time is waived when work is inspected on the same day
Correct answer: It adds a mandatory hold period before the area can be closed or reoccupied
Many firestop products require a minimum cure period before achieving rated performance; closing an area prematurely can void the system listing.
Question 3: Which scheduling approach BEST manages the risk of a firestop product being discontinued before project completion?
- Order only what is needed week by week
- Pre-order and store sufficient material for the entire project at the start
- Identify an approved alternate system in the submittal package (Correct answer)
- Request a project extension to source new products
Correct answer: Identify an approved alternate system in the submittal package
Including pre-approved alternate systems in the submittal package allows seamless substitution if a product becomes unavailable mid-project.
Question 4: A firestop installer discovers an unanticipated penetration not on the approved drawings. Who should be notified FIRST?
- The firestop material manufacturer
- The project inspector or AHJ directly
- The general contractor or construction manager (Correct answer)
- OSHA field office
Correct answer: The general contractor or construction manager
Unanticipated conditions must be reported to the GC/CM first so they can coordinate documentation, design response, and scheduling impacts.
Question 5: What is 'look-ahead scheduling' and why is it used in firestop project planning?
- A method of predicting material price increases
- A 2- to 6-week rolling plan that anticipates near-term work and resource needs (Correct answer)
- A post-project analysis of actual vs. planned dates
- A method for scheduling inspections 12 months in advance
Correct answer: A 2- to 6-week rolling plan that anticipates near-term work and resource needs
Look-ahead schedules (typically 2–6 weeks) help firestop crews anticipate upcoming penetrations, material needs, and inspection coordination.
Question 6: When multiple subcontractors create penetrations in a fire-rated barrier, who is typically responsible for ensuring each penetration is firestopped?
- The mechanical contractor only
- Each trade is responsible for firestopping its own penetrations unless otherwise specified (Correct answer)
- The firestop specialty contractor for all penetrations regardless of cause
- The general contractor performs all firestopping directly
Correct answer: Each trade is responsible for firestopping its own penetrations unless otherwise specified
Unless the specification assigns all firestop work to a single contractor, each trade is responsible for firestopping penetrations it creates.
Question 7: A firestop crew is delayed because the mechanical contractor has not yet installed pipes through a rated wall. What is the BEST scheduling response?
- Install temporary firestop until the pipes are installed
- Notify the GC, document the delay, and resequence available work (Correct answer)
- Firestop the wall completely and core-drill after pipe installation
- Halt all work on the project until the issue is resolved
Correct answer: Notify the GC, document the delay, and resequence available work
Documenting the delay and resequencing to other available work minimizes productivity loss and preserves the right to recover schedule impacts.
