SECTION 4 - SUMMARY OF WORK

4.1 Primary Focus

A. The project’s primary focus is updating four elevators in Building 400 at SAFB. Elevators one and two are traction type passenger units located on the north side of the facility.

Elevator three is a hydraulic freight elevator located on the south side of the facility.

Elevator four is a hydraulic passenger/service type elevator located adjacent to elevator 3 on the south side of the facility. The project will address the Cab Finishes, Controls, Doors, Door Hardware, Door Controls, Wearable Parts, Cab Lighting, and Overall Code Compliance.

4.2 Non-Proprietary Equipment

A. Non-proprietary elevator equipment, including controls will be specified. The project will use multiple vendors such as Smartrise Controls, Columbia Elevator, Alliance Elevator, MAD Elevator, LWI Elevator, Curion, and Peele as the basis of design. The vendors listed have proven track records of meeting “Non-Proprietary” specifications.

4.3 Field Data

A. The evaluation of the vertical transportation requirements detailed in this report are based on the Field Survey conducted. Additional requirements have been gathered via on-site reviews with building staff members, reviews with base facilities personnel, and performance monitoring data collected by monitoring equipment placed on various elevators.

B. An onsite survey was used to assess the condition of the existing equipment to help guide recommendations regarding the safety, reliability, and durability requirements for future equipment. Additionally, the surveys assessed overall code compliance with all applicable codes and standards. Broadly speaking, the surveyed elevator equipment is in average condition based upon the vintage and environments the equipment is installed in.

4.4 Performance Criteria

A. All elevator planning is based on providing “good” performance from an overall vertical transport system perspective. Most importantly, all elevator planning is based upon providing SAFB with elevators which meet appropriate safety, reliability, and durability standards. With regard to elevator performance, repairs and upgrades can only provide moderate performance improvements. Much of an elevator’s performance capabilities resides in the overall system design which will not be impacted in a basic repair/upgrade type project. The design will provide the best performance improvements as possible without sacrificing safety, reliability, or durability. Generally, an elevator’s performance can be evaluated by two distinct criteria; Average Interval and Wait Time.

Recommendations within this report will strive to improve these two criterium as they are the most readily recognized criteria for meeting facility personnel’s functional needs of elevators.

SECTION 5 - PROJECT OVERVIEW AND OBJECTIVES DISCUSSION

5.1 Qualifying “Sustain/Repair”

A. As a general statement of fact, commercial elevator systems, parts, and components are engineered and manufactured for a 20-year lifecycle. There are many factors which contribute to the actual lifecycle a system or component will experience. Heavily abused and/or used components such as Door Components tend to have a lower actual lifecycle.

With regard to Air Force funding practices, typically, in an elevator “Repair” project, the overall lifecycle of the elevator system has not been reached and is not in question. In a typical elevator “Sustain” project, the overall lifecycle has been reached and or exceeded.

5.2 General Condition

A. The general condition of the elevators surveyed in the Project Inventory List is “Below Average” by any industry standard. Therefore, with proper investment, the overall lifecycle of the elevators can be prolonged significantly.

5.3 Design Approach

A. The approach used for this project is proactive in nature and replaces major components and systems such as Controllers; Traction Hoist-Machines and Sheaves; Freight Door Controllers; Freight Doors, Tracks and Hardware; Freight Car Gates, Tracks and Hardware; Passenger Door Rollers, Closers, and Related Hardware; Passenger Door Operators, Related Hardware, and Car Lights.

B. This approach will allow for:

a. The maximum usage of Engineered systems to be installed and interfaced with one another.

b. Elevator mechanics to achieve the best possible installation alignments and instal-lation quality which will translate into the highest quality and reliability levels pos-sible.

c. The maximum standardization of parts and components across the maintenance portfolio allowing for the lowest level of parts proliferation for efficient and effective maintenance. In a large maintenance portfolio, parts interchangeability is a man-datory focus in order to reduce future maintenance costs and maximize unit up-time.

d. Allow for standardization of elevator key switches and keys in-line with the latest code requirements.

It would be expected that this approach will provide an additional 20-30 years of safe, reliable, dependable lifecycle of the elevators.

5.4 Non-Proprietary Definition

A.

6. Technical Support should be generally available to any Qualified Elevator Contractor. The Equipment Manufacturer shall provide a published Technical

Support telephone number, web portal, or online chat portal available to the Qualified Elevator Contractor during normal business hours within North America;

not subject to a specific time zone.

5.5 Code Review and Understanding of “Freight Elevators”

A. An understanding of Owner’s Liability and Liability Mitigation should be an academic element to any elevator project. A review of the applicable code requirements is necessary to gain this understanding. ASME A17.1/CSA B44 defines a Freight Elevator as:

1. An elevator used primarily for carrying freight and on which only the operator and the persons necessary for unloading and loading the freight are permitted to ride.

B. While conducting site surveys, the A/E learned through observation and user interviews, that the standard practice of Freight Elevator No. 3 usage is to allow “passengers” other than those “required” for “unloading and loading” of freight. In many instances, it was observed that building employees, including management, were utilizing Freight Elevator No. 3 as a common Passenger Elevator. This type of usage behavior places the owner at an extremely high risk of liability and potential litigation. In the unfortunate event that bodily harm should come to a “passenger” on a “freight elevator”, the litigation is very difficult to defend when the historical usage patterns clearly show that passengers have been acceptable.

C. It was also observed that the existing building layouts, existing elevators, vertical traffic requirements, and overall employee behavior, somewhat require that passengers be allowed to utilize the freight elevator. Therefore, it is recommended that the Freight Elevator be upgraded to fully comply with applicable codes under ASME A17.1/CSA B44 Section 2.16.4 which would allow for passenger usage of freight elevators. This upgrade would minimize the liability the owner carries. In the unfortunate event that bodily harm may be done to a passenger in a freight elevator, the owner would not be negligent in allowing passengers in an elevator which code specifically disallows passengers.

D. To accomplish this, applicable codes will dictate a few upgrades/modifications.

However, the primary upgrade required to the freight elevator is the substitution of Car Gates with Car Doors. Fundamentally, the two operate the same. The difference being that the Car Door is solid so to minimize pinch-points and “severing-points”. A detail of the difference is as follows:

5.6 Code Review

A. General Comments: A code assessment was made to assess the existing elevator installations against applicable codes in which each unit is subject to in the current state.

In the case of the two (2) Passenger Traction Elevators, Elevators #1 and #2, there were “severe” or “dangerous” code deficiencies observed. If the elevator project associated with this report does not move forward, the “severe” or “dangerous” code deficiencies demarked below should be addressed by SAFB. Code deficiencies are detailed below respective to each elevator reviewed.

B. Reference to ASME A17.1-2013/CSA B44-13 emergency two-way communication requirements:

2.27.1.1.6

5. GAL – Passenger Elevator Doors, Door Components and Door Operators.

6. Wurtec or GAITronics – Elevator Emergency 2-Way Communication Devices

7. MEI or Alliance Elevator Solutions – Hydraulic Power Units and Components

5.8 Elevator Performance

A. Generally, the performance of these elevators is not the focal point of this project.

Historical usage and observed usage do not dictate that performance must be the focal point. However, in many instances, building patrons would benefit greatly if the elevators had improved performance. For the average usage most of these elevators experience, this report will deem “Performance” to be measured by: Average Interval and Wait Time.

Simplistically, this report will deem the average time it takes a building patron to have an elevator arrive upon the patron placing a Hall Call as being the focal Performance criteria to improve when feasible.

B. As a practical rule, elevator speed and capacity are the primary factors in determining intervals and wait times. However, door performance, or speed and timing of doors, are also factors. This report will not address primary factors such as elevator speed and capacity. The report will take into consideration overall door performance when feasible as a secondary method to improve overall elevator performance. Elevator performance tends to be the most recognized improvement by building patrons in projects such as this. Therefore, an improved performance is essential when feasible.

SECTION 6 - ANALYSIS AND DESIGN APPROACH

6.1 General Comments

A. The design approach is detailed below and broken down relative to each respective elevator. At this point, no one specific vendor is detailed as a mandatory vendor to meet a specific criterion. Generally, all proposed components can be provided by a minimum of 2-3 vendors within the North American market.

B. The design approach for the Passenger Traction elevators is to replace the existing AC Geared hoist machines with AC Gearless hoist machines providing SAFB with high efficiency, lower power consumption machines. AC Gearless machines also provide quieter operation, smoother starting, greatly improved performance, and near maintenance free operation.

C. The design approach for all elevators relative to Hall Fixtures will be to replace all fixtures with Flush-Mounted fixtures providing oversized faceplates where necessary to cover unsightly holes or existing cover plates

D. The design approach for all passenger elevators relative to Door and Door Operation shall be to replace the door operators with smoother, more efficient, linear door operators providing SAFB with much more reliable and safer door operation.

E. The design approach for the Freight Elevator #3, will reduce the liability assumed by SAFB relative to Passengers utilizing the Freight Elevator. The Freight Elevator will be upgraded to fully comply with applicable codes under ASME A17.1/CSA B44 Section

2.16.4 which would allow for passenger usage of freight elevators.

Below is a complete listing of all elevators/lifts in the project.

SECTION 7 - INFRASTRUCTURE

7.1 Architectural

A. Building 400 has three stories above grade and a partial basement. The three floors divided into twenty numbered modules (MODs) are served by three passenger elevators and one freight elevator. Elevators 1 and 2 are located on the north perimeter of the building. Elevators 3 and 4 are on the south perimeter. Only the freight elevator serves the basement.

Figure 1 - Building 400 MODs (Floors 1-3)

B. Elevator lobbies should adhere to the SAFB Facilities Excellence Plan.

C. Existing building finish modifications depend largely on the selected course of action from the recommendations. If new elevators are installed the door openings into the corridors will likely need to be modified and the wall/floor finishes will need to be updated.

1. Provide 12”x12” unglazed ceramic or porcelain as an accent.

2. Basis-of-Design Colors: Crossville, Cotto Americana with Ardex grout

3. Coordinate final manufacturer / color selection with Base Architect; other acceptable manufacturers and/or colorways are Crossville, Vista Americana; or Florida Tile (Cliffside or Continent)

D. Modified walls will be painted the full length in front of the elevators. Tile base and flooring will be replaced in the corridor along the width of the elevator lobby recess on the north and for a length of 30 feet along the south corridor.

E. The following photos illustrate the existing corridor finishes to be matched:

7.2 Structural

A. The building is a 3-story steel framed office building with a partial basement. The typical framing bays are 31’-3” x 40’-0”.

1. Roof: The roof framing consists of 4” thick concrete on top of 1 ½” deep metal decking. The roof deck spans to wide flange purlins spaced at 6’-8” on-center.

The purlins span 31’-3” to wide flange steel beams and wide flange columns.

2. 3rd and 2nd Floor: The floor framing consists of 3” thick concrete on top of 1 ½” deep metal decking. Similar to the roof framing, the floor deck spans to wide flange purlins spaced at 6’-8” on-center. The purlins span 31’-3” to wide flange steel beams and wide flange columns.

3. 1st Floor and Foundation: The structural floor portions of the main level are framed as noted above for the upper level floors. The foundation system consists of conventional concrete spread footings and concrete slab-on-grade.

4. Lateral resisting elements: Lateral elements to resist wind and seismic forces are resisted by diagonal double angle bracing.

5. Elevator support framing: Support for the elevator and elevator rails is provided by structural steel framing fastened to the main roof/floor structures. The south passenger elevator is supported by an elevated structural slab.

7.3 Mechanical

A. Elevator 1 & 2 share the same elevator machine and a hoist way. The machine room is cooled with an independent air handling unit. The room also has 450-cfm of air exhausted out of it and transferred from the adjacent lobby and corridor. The exhaust fan also serves the adjacent restrooms and janitor’s closet.

B. Elevator 3 & 4 share the same elevator machine and a hoist way. The machine room and hoist way of elevator 3 are supplied with 1200-cfm and 900-cfm respectively from evaporative units, EC/TB-311 and 320, located on the third floor. The evaporative cooling units also serve the basement cable entry vault, first level cable vault, basement corridor, basement electrical room, and provide outside air to AHU/TB-002. The 2015 International Building Code (IBC) section 3005.2 requires elevator machine rooms to have independent ventilation or air conditioning systems, which this machine room does not have. However, the amount of airflow appears to adequately cool the room.

Changing the system will likely negatively affect building pressurization. Air from the machine room is relieved via a roof mounted relief vent. The roof vent is equipped with security man bars.

C. UFC 3-600-01 requires the elevator machine rooms have the same fire resistance rating as the elevator shaft that it serves.

1. The supply and return diffusers in the machine room for elevator 1 & 2 are equipped with 1-hour fire dampers.

2. The supply and return ducts in the machine room for elevator 3 & 4 are equipped with 1-hour fire dampers. The supply duct serving the elevator 3 hoist way is equipped with a 1-hour fire damper.

D. Design Approach:

1. Currently there are no required upgrades to the mechanical systems serving the elevators.

7.4 Electrical

A. Elevator 1 & 2 – Traction Type Passenger Elevators

1. Power to elevator 1 & 2 is derived from Motor Control Center MCCT14, each elevator is equipped with a 100A safety disconnect and an 80A shunt trip breaker.

The elevator motors are both 50Hp, 480V, 3-phase 1200rpm motors. The elevator cab lights are fed from panel T1L4D circuits 14 and 16 via safety disconnect switches.

2. The lights in the elevator machine room are 4’ long 2-lamp fluorescent strips with protective bulb covers and provide adequate illumination. The required illumination is 19 ft-c at the floor.

3. There is a compact fluorescent fixture with wire guard in each side of the pit and a similar fixture on both sides at the top of the hoist way. Lighting levels in the pit and at the top of the hoist way is inadequate. The required illumination level is 10 ft-c at the floor of the pit.

4. The work light fixture on the bottom of each elevator cab is non-functioning.

5. There is a light switch at the top of the ladder entering each side of the pit.

6. The machine room is equipped with GFCI protected receptacle near the entrance door.

7. Each side of the elevator pit is equipped with a GFCI protected receptacle that is mounted at approximately 5’ above the floor of the pit. The receptacles are located too high to meet current code.

B. Elevator 3 – Hydraulic Type Freight Elevator

1. Power to elevator 3 is derived from Motor Control Center MCCTB1, it is equipped with a 100A safety disconnect and an 80A shunt trip breaker. The elevator pump motor is a 50Hp, 480V, 3-phase unit. The elevator cab lights are fed from panel TBL1-22 via a safety disconnect switch.

2. The lights in the elevator machine room are 4’ long 2-lamp fluorescent strips with wire guards and provide adequate illumination. The required illumination is 19 ft-c at the floor.

2. Provide four new 4’ long LED strip fixtures with wire guards (two on each side at the top hoist way in the overhead space) for elevators 1 & 2. Remove the existing fixtures.

3. Lower the receptacles in the pit for elevator 1 & 2 to a code compliant height.

4. Provide four new 4’ long LED strip fixtures with wire guards (two on each side at the top hoist way) for elevator 3 & 4.

5. Change standard receptacles in the elevator 3 & 4 machine room to GFCI protected devices.

6. Provide new GFCI receptacle in elevator pit.

7.5 Fire Alarm and Detection

A. The fire detection system for the elevators was evaluated for compliance with UFC 3- 600-01. The following criteria was extracted from the UFC for the applicable Elevators:

1. Smoke detectors are required for all lobbies not open or exposed to the exterior.

2. Smoke detectors are required in all elevator machine rooms.

3. Smoke detectors are not required at the top of the hoist way.

4. Smoke detectors are not required in the elevator pits.

5. Activation of the shunt trip breaker is required by direct connection to the sprinkler flow switch that serves the machine room/hoist way.

6. Listed control relays must be provided within 3’ of the elevator controllers.

B. Elevators 1 & 2 are traction type passenger elevators and have smoke detectors in the lobbies and in the machine room, but do not have detectors in the pit or top of the hoist way. From a detection standpoint, elevators 1 & 2 are UFC 3-600-01 compliant.

However, the control relays are located on the opposite side of the room and are approximately 7’ from the controllers which is non-compliant. Also, in the machine room the relays are not labeled. The shunt trip breaker is activated via an addressable fire alarm control relay that is activated by sprinkler flow switch (see discussion in fire protection section).

C. Elevator 3 is a hydraulic type freight elevator and has smoke detectors in all the interior lobbies, smoke detectors in the elevator machine room and has a detector at the top of the hoist way. From a detection standpoint, elevator 3 is UFC 3-600-01 compliant. The control relays are located on the same wall as the controller and are within 3’ of the controller. Some of the relays are labeled and some are not. The shunt trip breaker is activated via an addressable fire alarm control relay that is activated by sprinkler flow switch (see discussion in fire protection section).

D. Elevator 4 is a hydraulic type service/passenger unit and has smoke detectors in all the lobbies and smoke detectors in the elevator machine room. From a detection standpoint elevator 4 is UFC 3-600-01 compliant. The control relays are located on the same wall as the controller and are within 3’ of the controller. Some of the relays are labeled and some are not. The shunt trip breaker is activated via an addressable fire alarm control relay that is activated by sprinkler flow switch (see discussion in fire protection section).

E. Design Approach: The following modifications are required:

1. Remove the detector at the top of the elevator 3 hoist way.

2. Relocate the Monitor and Control Modules for elevators 1 & 2 between the controllers within 3’ of them.

3. Provide new labels on all Monitor and Control relays.

7.6 Fire Protection

A. Fire Protection for the elevator systems were evaluated for compliance with UFC 3-600-

01. The following criteria was extracted from the UFC for the applicable Elevators:

1. The machine room shall have the same fire resistance rating as the elevator shaft that it serves.

2. All elevator lobbies must be sprinklered.

3. All elevator machine rooms must be sprinklered and the heads must have protective wire guards.

4. The sprinkler line serving the machine room must have a supervised shut-off, check valve, supervised water flow switch and a test valve located outside but adjacent to the machine room.

5. Activation of the water flow switch shall remove power to the elevator served by the machine room, by direct connection to the shunt trip breaker.

6. Sprinklers are not required at the top of the hoist way.

7. Sprinklers are required in the pit area for hydraulic elevators but are not required for traction elevators. Note: UFC 3-600-01 defers to NFPA 13 pit sprinkler requirements.

B. As described above, the UFC requires that the shunt trip breaker be directly wired to the water flow switch for activation. Meaning that as soon as water begins to flow, power is removed from the elevator controller. The configuration at B400 is nearly compliant with this requirement. The Flow switch is monitored by an addressable monitor module, once water flow is initiated, the monitor module sends a signal to the FACP which in turn sends a signal to an addressable control module (relay). The control module closes a contact and applies 120VAC to the shunt trip breaker, which causes it to trip and disconnect power to the elevator controller. Although, the shunt trip breaker is ultimately controlled by the sprinkler flow switch, it is not directly connected to the flow switch. The SAFB Fire Department requires that the flow switch be directly connected to the flow switch.

C. Elevators 1 & 2 are traction type passenger elevators. The machine room and lobbies are sprinklered, but the pit and top of the hoist way are not. The sprinkler line serving the machine room has a supervised shut-off, check valve, supervised water flow switch and a test valve located outside and adjacent to the machine room above the ceiling in the corridor to the east. From a fire sprinkler perspective, elevator 1 & 2 are deemed to be in compliance with UFC 3-600-01. Note: Elevator 1 & 2 share the same machine room, pit and top of hoist way.

D. Elevator 3 is a hydraulic type freight elevator. The machine room, lobbies and pit are sprinklered, but the top of the hoist way is not. The sprinkler line serving the machine room has a supervised shut-off, check valve, supervised water flow switch and a test valve located outside the door to the machine room. From a fire sprinkler perspective, elevator 3 is deemed to be in compliance with UFC 3-600-01. Note: Elevator 3 & 4 share the same machine room and top of hoist way, but elevator 3 has a dedicated pit.

E. Elevator 4 is a hydraulic type service/passenger elevator. The machine room and lobbies are sprinklered. The top of the hoist way is equipped with a sprinkler pipe but there are no sprinkler heads, so it is affectively not sprinklered. The bottom of the hoist way shares space with the machine room and the area directly under the shaft is sprinklered. The sprinkler line serving the machine room has a supervised shut-off, check valve, supervised water flow switch and a test valve located outside but adjacent to the machine room. From a sprinkler perspective, elevator 4 is deemed to be in compliance with UFC 3-600-01. Note: Elevator 3 & 4 share the same machine room and top of hoist way, but elevator 4 has no pit

F. Design Approach: The only required modification to the fire sprinkler system is to direct connect the flow switches to the power shunt trip devices. The existing flow switches are manufactured by Potter, model VS-SP so they are already rated for 15 at 120VAC.

7.7 Environmental

A. As noted in the elevator assessment, elevators 3 & 4 are leaking hydraulic oil at the jack cylinders. SAFB has provided a Material Safety Data Sheet (MSDS) for the leaking oil that indicates the fluid is Chevron Hydraulic Oil AW 32, 46 or 68 and is considered Polychlorinated Biphenyl (PCB) Free. As a result, hazardous material disposal practices for PCB is not required

B. HAZARDOUS MATERIALS

1. Contractors using any type of Hazardous Materials (HM) on SAFB must comply with the review and approval process and shall provide the Contracting Officer (CO) with a list of proposed materials that it plans to use on the installation during the performance of the contract.

2. At least 30 days prior to the contract start date, the contractor shall provide to the CO a copy of the 3952 form, SAFB hazardous material tracking form - material and approval submittal, listing all materials that will be utilized during the contract period as well as the current Safety Data Sheet (SDS). The 50 civil engineering squadron environmental management element (50 CES/CEIE) will determine if any of the proposed materials are classified as hazardous and are covered under emergency planning and community right-to-know act (EPCRA) (42 U.S.C. 11001- 11050). If they fall into this category 50 CES/CEIE will issue an authorized use list to the co for this contractor.

3. Once on site the contractor will report through the co to the 50 Logistics Readiness

4. If additional HM is required during the course of the contract or if there is a change to existing HM, the contractor shall update the 3952 form and provide an SDS for each HM through the co to 50 CES/CEIE. The contractor shall submit the new authorization request Not Later Than (NLT) 15 days prior to delivery of the HM onto SAFB.

5. For each contractor-identified chemical that 50 CES/CEIE determines does not meet the definition of a HM, EPCRA requirements do not apply. 50 CES/CEIE will notify the co that the contractor has authorization to bring and use that material on the installation without reporting usage use unless required under green procurement program or specifications requiring data submittals.

6. The main contractor is responsible for reporting all sub-contractors HM usage from the date of hire throughout the duration of their contract through the co to 50 CES/CEIE. No HM, lubricants, oils, liquids or related materials shall be deposited in the refuse containers on the installation.

7. The contractor shall not use products that are, or contain diisocyanates, dioxins and dioxin-like compounds, extremely hazardous substances, Ozone Depleting Substances (ODS), cfcs or persistent bio-accumulative and toxic chemicals. Any HM containing any of these banned substances will not be allowed on the installation.

8. If the HM request is for a Class I ODS, 50 CES/CEIE will ensure there is an applicable and current air force Senior Acquisition Official (SAO) approval for contract Class I ODS requirements before approving the HM authorization and made available to the contractor. The CO will also maintain a copy of the SAO approval in the contract file as required by AFI 32-7086.
