Fire Safety Consultants, Inc. Summer 2020 Newsletter

PRESIDENT’S MESSAGE

An FSCI update from Keith Frangiamore, FSCI President

Tough Times
Since our Spring Newsletter, we have been through the most challenging
time of my lifetime. From the COVID-19 virus pandemic,
subsequent lockdown, massive unemployment and loss of business,
to social injustice and subsequent protests throughout the country.
Like many other businesses, FSCI has been greatly affected by the
lockdowns. During the past few months, we have been adjusting to
the various state and municipal government orders across the country
where we have clients. FSCI struggled to provide the level of
service our clients expect as we complied with CDC and state employee
health safety guidelines, especially the staffing limitations at
our offices.
We appreciate everyone’s patience as these health safety guidelines
and lockdowns impaired our ability to maintain our standard turnaround
times. We are now back to full staffing and have reinstated
our expedited plan review policy, allowing for 5 day expedited plan
reviews, which was suspended in early April.

Busy Times Ahead
FSCI continues to work on many large projects for essential service
companies such as logistics companies and hospitals. They are in
various stages of completion from plan review to field inspections.
As we anticipate easing of safety restrictions and businesses begin
reopening, FSCI is well positioned with our full staff ready to resume
providing quality services to all clients and customers.
In addition, FSCI has many projects returning that were put on hold
due to the COVID-19 pandemic where state orders shuttered businesses
and others where health safety concerns precluded FSCI
from entering buildings, such as senior housing, assisted living and
skilled nursing facilities.
Please stay safe, protect others, and help us all work toward a healthy
future!

Building Code Submittals – How to Get It Right

Fire Safety Consultants, Inc. (FSCI) conducts full and partial third-party, building and life safety plan reviews for many of its municipal and fire district clients. We review the submitted plans using the model codes and our client’s amendments for compliance. The focus of this article is on the building code portion of a plan review submittal.

Lack of sufficient detail on drawings, or missing drawings, is the primary reason that building and life safety plans are not approved.  Plans submitted for permit review must be more than lines on paper or in a CAD file.  More detail is always better than less. For example, one architect might submit two or three dozen architectural and structural sheets for a building while another architect will submit four or five pages for the same basic building.  Typically, the larger plan set stands a better chance of being approved; or, having fewer comments which need to be addressed in a second submittal.

The number of pages submitted for review is not the sole reason in determining the likelihood that the plans will be substantially compliant with the applicable building code.  Often the information and detail included on the additional plan sheets in an architect’s submittal is likely to answer many of the questions that the plan reviewer may have when comparing the plans to the requirements of the jurisdictions adopted codes.

To submit a compliant set of construction plans the architect should review the code, section by section, to ensure that the design of the building meets the building code in effect within a jurisdiction.   A good, thorough plan reviewer, while reviewing construction plans, goes through the code, section by section, using a checklist or other plan review tools.

Construction Documents

The International Building Code (IBC) requires in Chapter 1, Administration, that construction documents be submitted that sufficiently indicate the location, nature and extent of the work proposed.  The IBC further states that the submittal must show, in detail, that the construction documents conform to the codes and relevant laws, ordinances, rules and regulations as determined by the building code official.

While the code expects sufficient detail, often reviewers receive incomplete building details such as:

Builder to construct stairways in accordance with the building code.” Or,

“The owner will determine the interior finishes of the assembly areas before occupancy.” 

The first statement does not describe to the plan reviewer anything about how the architect wants the stairway constructed. The second statement doesn’t include the flamespread and smoke developed ratings of the finishes that may be installed within the assembly occupancy.

Complete and detailed drawings is the key to having construction plans approved on the first review.

Necessary Elements of Construction Documents

 In addition to detailed construction documents, which we will discuss later in this article, the IBC also specifically requires that construction documents address the following areas:

  • Fire protection system shop drawings
  • Means of egress
  • Exterior wall envelope
  • Site plan

Fire protection system shop drawings

Although some jurisdictions may require fire protection system shop drawings prior to the issuance of a building permit, they are most-often submitted separately from the building construction documents.  The building official or fire code official should be contacted in advance to determine when they want to receive fire protection shop drawings or preliminary design information.  Typically, building plan submittals only require a note that sprinklers will be provided and the type of system that will be used (NFPA 13, 13R, or 13D).  The reviewer will also look to see if a fire alarm system is provided.

Means of egress

The review of a building or structure’s means of egress is arguably one of the most important parts of any construction document review.  A successful means of egress submittal will clearly show:

  • The location and size of all doors and openings
  • The occupancy load for all rooms and spaces on each floor
  • The capacity of, or a means to determine, all exit accesses, exits, and exit discharges
  • The location of all exit and emergency lighting fixtures
  • Door hardware information include the type of door release and locking on each egress door

Exterior wall envelope

The construction of the exterior wall envelope is regulated by the IBC.  Requirements ensure that the construction of the exterior wall will resist moisture and is energy efficient.  Exterior walls often act as bearing assemblies which must be designed to support roofs or floors.  Where exterior walls require fire-resistance due to the building’s construction type, or the wall’s proximity to other buildings or lot lines. Construction documents must show the hourly fire rating, the construction of the wall, and shall include the fire-resistive design number of the assembly.

Site plan

Site plans are a major part of the submittal for new buildings and when a building receives an addition.  Site plans are necessary as they show the plan reviewer where the building will be located on the lot relative to other buildings and lot lines.  A building’s position on a lot determines the need for fire-resistance rated exterior walls and the protection of openings.  Additionally, site plans may need to be supported by grading plans that show the elevation of the first floor relative to surrounding grades and flood elevations.  Where a fire code review is being conducted, site access, the location of fire hydrants, and watermain sizing should be indicated on the site plan.

Occupancy, Special Uses, and Construction Classifications

 The design, and the resulting review, of any building begins with determining the correct occupancy and construction classifications.  Chapter 3 of the IBC provides very good examples of the types of operations that fall into each occupancy classification.  Chapter 6 explains the differences in the available construction types. The review of a building cannot begin until the correct occupancy classification and construction-type designations are assigned to a building. These play an important role in determining many of the other requirements found in the building code.

Chapter 4 of the IBC provides specific detailed requirements for special occupancy types.  Designers should review the different occupancy types that are discussed within this chapter.  There are twenty-eight different occupancy types covered within Chapter 4 such as covered malls, high-rises, atriums, motor-vehicle rated occupancies, buildings using or storing hazardous material, and I-2/I-3.

General Building Heights and Areas

Knowing the occupancy classification and construction type for a building is necessary to determine if a building is within its maximum permitted floor area, height, and total floors.  Chapter 5 provides three tables which the plan reviewer will use to determine if the architect can use the proposed construction type.

Chapter 5 also deals with conditions where multiple use groups will occupy the same building.  If not indicated on the construction plans, the plan reviewer may need to ask the architect which separation option will be used in the building’s design.  The decision on which design is used can have a large impact on how many of the code requirements are applied to the building.  In most cases, and where possible, selecting the non-separated mixed-use option makes designing and reviewing a building simpler.

Fire-Resistance of Structural Members and Assemblies

Having determined the construction type of a building and its distances to other buildings or lot lines, the architect must provide the appropriate fire-resistance rating to structural members, walls, and enclosures.  The plan reviewer will check that the correct fire-resistance rating has been chosen and that a correct wall assembly, ceiling/roof assembly, or structural member protection system has been included in the plan details.  It’s insufficient to provide just a note that an assembly has an hourly rating of 1 or 2-hours.  An hourly rating must correspond to an assembly which has been evaluated by a nationally recognized testing lab.  Therefore, an assembly design number must be included in the drawings along with a detailed wall section describing how the assembly is to be built.

Interior Finishes

An architect may provide an interior finish schedule within the plan set.  Often the schedule lacks the necessary information required by IBC Chapter 8.  Flamespread and smoke-developed ratings are key to assuring that finishes within a building will not contribute to a fire’s spread and will not result in large quantities of smoke being produced which will hamper evacuation from the building.  The architect of a building must review the interior wall and ceiling finish requirements, and the required classifications for interior floor finishes.

Fire Protection and Life Safety Features

Based on a building’s occupancy classification, the building area, often a building’s occupant load, and at times, the building’s height, architects need to review Chapter 9 for fire suppression or fire alarm system requirements. When the systems are required, they must be noted on the construction plans.

Chapter 9 also includes the requirements for alternative extinguishing systems, standpipe systems, portable fire extinguishers, emergency alarm systems, etc. and if required must be noted on the construction documents.

Mean of Egress

 The plan reviewer must confirm the correct occupant load of rooms, spaces, and floors within the building, or outside of a building where the occupants must exit through the building from areas such as a roof-top spaces.  The design professional must provide this information to the plan reviewer in order to determine if the building design complies with the means of egress requirements.

A complete means of egress submittal will clearly show the location and size of all doors and openings, egress corridors, and exit discharges to allow for the calculation of the maximum capacity of provided exits.   The occupancy loads provided are then compared against the exit capacity of the exit access, exits, and exit discharges.

Architects should review the requirements for maximum exit travel distance, maximum common path of travel, and maximum permitted corridor dead-ends.  Travel distances are correctly calculated using right angles.  Architects sometimes draw a diagonal line from the most remote corner of a room to the egress door. However, unless the room is without furniture or other floor obstructions, most plan reviewers will not accept this method of determining travel distance.

Exit and emergency lighting shall be shown at least on the electrical drawings.  A frequent inconsistency found on plans is where the architectural and electrical plans show different exit and emergency lighting locations within the building.  Another frequent deficiency found is a lack of emergency lighting on the exterior of the building at the exit discharge.

Rooms and spaces with an occupant load of 50 or more (and in some instances less) require two, remotely located egress doors and exit signage.  The minimum occupant load, where fixed seating is not provided, is based on Table 1004.5 unless a lesser number is approved by the building code official.  The common path of travel from a room or space may also trigger the need for a second exit.

Doors are a critical egress component.  The hardware on egress doors is regulated by Chapter 10.  Plan reviewers will review doors in the egress path and compare the hardware on the doors with requirements in the IBC.  A lack of detailed door hardware descriptions prevents the plan reviewer from verifying code compliance.  Swinging egress doors in Group A and E occupancies with an occupant load of 50 or more, and H occupancies, must be provided with panic hardware with limited exceptions.  There are also panic hardware requirements for electrical rooms with equipment rated 1,200 amperes or more and over 6-feet in width.

Stairway requirements are numerous.  Frequent errors found on plans are a lack of handrail and guardrail details, incorrect tread and riser details, and stairway enclosure deficiencies.  Additionally, the lack of a barrier under a stairway to prevent a person from striking their head on the stairway stringers is often found missing on the construction plans.

Assembly occupancies have additional means of egress code requirements in Chapter 10 which will be checked by the plan reviewer.

Accessibility

An accessibility plan review compares the requirements of IBC Chapter 11 and ICC A117.1 with information indicated on the construction plans.  In some states, additional accessibility requirements may exist which the architect should review to ensure compliance.  Typically, accessibility reviews are conducted as a separate part of the plan review process.

Additional Requirements

The IBC includes several hundred pages of additional code requirements which must be reviewed by the architect and incorporated into the construction plans.  These requirements will be referenced during the plan review process.  Some of the more common chapter requirements include:

  • Interior environment concerns
  • Construction of exterior walls
  • Structural design including wind, snow, live and dead, floor loading
  • Special inspections
  • Soil investigation procedures
  • Elevator and conveying systems
  • Safeguards during construction

In Closing

 Well detailed construction documents submitted for review often can lead to a faster permit issuance resulting in a project being completed in a timely manner.  If you have additional questions about plan review submittal and the IBC, please reach out to our team.

Little Known Facts

NFPA 13 25.2.2.1.1 – Dry Pipe and Double Interlock Preaction System(s) Air Test

For a quite a while there has been an option which allowed a system working pressure hydrostatic test to be performed when minor modifications were made to an existing system. However, if the system was a dry-pipe system you were also required to perform a 24-hour air leakage test on the system. Starting in the 2016 edition of NFPA13 there are now permitted alternative tests for air leakage testing when modifications have been made to an existing system. These options include an air pressure test of 40 psi for a duration of 2 hours with a permitted pressure loss of up to 3 psi being an acceptable loss.  NFPA 13 also allows for an air pressure test which has the system remain at normal system air pressure for 4 hours with the air source turned off.  During this test, the low-pressure alarm cannot activate.

NFPA 13 (2013) 8.17.4.6.1, 25.2.5.1, NFPA 25 (2014) 13.6.3  Forward Flow Testing of Backflow Prevention Valves

Since 2013, NFPA 13 has required that a permanent means be provided in order to facilitate the forward flow testing of the backflow prevention assembly at no less than the system demand, including hose allowances, as required by NFPA 25. This requirement is often overlooked during the design of a new system but plays an important role in maintaining a fire sprinkler system. The issue is that NFPA 13 does not specifically indicate how this requirement is to be met. Some of the most common solutions are to bypass the fire department connection check valve with a normally closed supervised indicating valve, provide hose connections downstream of the backflow prevention assembly, provide a dedicated forward flow test header, or size the main drain to handle the minimum flow rate of the system demand. For systems with a fire pump, the annual pump test header can be used for this test. Contractors often want to flip or remove the check valve on the FDC piping; however, this is not allowed. This practice is only permitted for systems installed prior to NFPA 13 (2013 ed.) being adopted. Modifications to the system should not be needed in order to conduct this flow test.

Illinois Accessibility Code Fire Alarm System Update

For our Illinois readers, the latest edition of Illinois Accessibility Code (IAC) became effective on October 23, 2018.  While the regulations within the current IAC have come more in line with those found in the 2010 Americans with Disabilities Act, there are still differences (which are italicized in the IAC).

One major difference can be found in Section 215.3 involving Employee Work Areas.  Section 215.3 reads: “Where employee work areas have audible coverage, visual alarms complying with 702 shall be provided.”  Section 702 adopts the 2013 edition of NFPA 72.  Employee work areas, as defined by Section 106.5, are spaces used only by employees and used only for work.  An example of such would be a single-user office.  The prior edition of the IAC, through the U.S. Architectural and Transportation Barriers Compliance Board Bulletin #2: Visual Alarms, did not require single-user offices to have visual signals unless the employee using the office had a hearing difficulty and asked for a reasonable accommodation from the employer.  The latest edition of the IAC would require, by Section 215.3, a visual appliance in each single-user office as each such office would be required to hear a fire alarm signal that was sounding.

There may be instances where the flash effect from a visual appliance located outside of the office may be seen (directly or in-directly) within the office.  In this case the AHJ may accept the visual appliance as serving the room.  The AHJ should evaluate the likelihood that the flash effect from outside the room will always be visible within the room.  Closed office doors, or curtains on office windows cannot obstruct the flash from the visual appliance located outside of the office.  Additionally, when the visual appliance located outside of the office is to be used to cover the individual office(s), appliance spacing must meet the requirements of NFPA 72, Chapter 18.  The coverage area outside, and within, the office(s) must be considered in the design of appliance spacing.
