SECTION II —

HIGH-RISE ELEVATORS 1-4

SUMMARY AND RECOMMENDATIONS

A. GENERAL

During our survey, existing passenger elevator components were checked to determine overall condition and suitability for continued use. In addition, machine room, hoistway, and pit spaces were reviewed for compliance with current codes. This section reviews the results of our equipment survey.

B. EQUIPMENT DISPOSITION

The elevator systems in the building were manufactured and installed by Fujitec America. The existing elevator equipment is in average condition for this vintage of equipment.

High-rise passenger elevators, Cars 1-4:

1. Rated capacity of 3,500 lbs.

2. Travel speed of 700 fpm.

3. Serve 16 landings, Floors 1-16.

4. Installed in 1997.

Existing controls are original and were engineered in 1995, and the installation was completed in 1997 by Fujitec America. Parts are still available for the DC gearless elevators with DCD-301 controls; however, the technology is outdated, and the support and technician's knowledge of this product is limited. The DC hoist machines are Fujitec 110T hoist machines. The machines are in above average condition for the vintage of the equipment. We recommend using a third-party motor testing company to review the machines in detail to determine efficiency and validate anticipated remaining life-cycle for solutions based on reuse, or refurbishment and reuse, as well as developing an estimate of operation costs and maintenance cost (compared to AC replacement) over the projected post-modernization life-cycle. The alternate option would be replacement with an AC machine. It is unknown how long Fujitec will continue to provide support on the existing controls. The controllers are over 20 years old and will continue to be problematic. Technical support and engineering support is limited. These systems were not installed in the US in large numbers, so the technical capability and resources of the original manufacturer is limited, and capability to support the system by local contractors is more limited.

The original GAL MOHL door operators were commonly installed as they were reliable and easy to maintain. Today, there are new “closed loop” door operators that can be retrofitted to this system and used with the existing door equipment. The hoistway door tracks and hangers can be retained. All door rollers, pickup rollers and interlocks should be replaced. The improved “closed loop” door control provides a variable speed drive that can adjust the door motor for potential stack affect with digitally encoded feedback. The “closed loop” control also improves passenger safety by its ability to adjust for door closing force. We recommend replacing the existing operators with new GAL MOVFR harmonic or MOVFE linear operators for all the elevators.

Existing signal fixtures are obsolete and dated. Planning for replacement should also include new hall and car fixtures as well as replacement of the multi-light hall position indicators at the Lobby level. Fixtures can be manufactured to match the existing design, style and finish of the original design.

The elevator cab interiors are original and in good condition. The cab interior finishes can be retained.

Changes in equipment design and technology have made the existing dispatching system, motor control, and door operation obsolete. Ascending car overspeed protection is required to meet current code requirements when modernizing elevator controllers. A modernization of the elevator equipment will likely require coordination and possible upgrades to existing Fire Alarm system and the USMS security system.

A summary of such work is defined in Appendix B – Related Building Systems Work.

October 16, 2019

Seismic upgrades can be included on the project as required by GSA Region-10 Policies, the P-100, and / or USMS guideline, however per national codes and standards they are not required unless the car and counterweight rails are altered. The rails do not currently have seismic fishplates, which are rail attachment supports. If seismic compliance is determined to be necessary then guide rails, supports, fastenings, and joints will need modified or replaced unless per the exceptions that permit those items of different design and construction than those provided for in ASME 2.23 which “…shall be permitted to be retained provided they are in accordance with sound engineering practice and will adequately maintain the accuracy of the rail alignment.” Finally, a modernization of the elevator equipment will require upgrades to existing building for Code compliance within limitations of existing structure. A summary of such work is defined in Appendix B – Related Work.

C. MODERNIZATION SCOPE

Planning will include development of a specification Section 14220 which will outline a detailed scope of work following the summary below.

As most new microprocessor-based car and motor controls are “proprietary” in nature, the specifications should include the requirements to provide the necessary diagnostic service tools and technical manuals to provide maximum flexibility in contracting for future maintenance. As an alternative, non-proprietary third-party controls could be specified, however, they will result in an increased initial installation cost of approximately 10% which may or may not be recovered (or may even be exceeded) over the operations an maintenance of the equipment during its life-cycle.

In addition to Section 14220, Lerch Bates will provide general Terms and Conditions specification sections. A partial list of those documents include: Instructions to Bidders, Quotation Form, Summary of Work, Alternates, Project Procedures, Submittals, Related Work, and Interim and Long-Term Elevator Maintenance. The bidding community is familiar with the Lerch Bates documents and the tendering process.

We recommend that the building work be included in the elevator contracts for a turnkey project.

SECTION III —

LOW-RISE ELEVATORS 5-8

SUMMARY AND RECOMMENDATIONS

A. GENERAL

During our survey, existing passenger elevator components were checked to determine overall condition and suitability for continued use. In addition, machine room, hoistway, and pit spaces were reviewed for compliance with current codes. This section reviews the results of our equipment survey.

B. EQUIPMENT DISPOSITION

The elevator systems in the building were manufactured and installed by Fujitec America. The existing elevator equipment is in average condition for this vintage of equipment.

Low-rise passenger elevators, Cars 5-8:

1. Rated capacity of 3,000 lbs.

2. Travel speed of 450 fpm.

3. Serve 8 landings, Floors 1-7a.

4. Installed in 1997

Existing controls are original and were engineered in 1995, and the installation was completed in 1997 by Fujitec America. Parts are still available geared traction elevators with Exceldyne 330 controls; however, the technology is outdated, and the support and technician's knowledge of this product is limited. The geared machines are currently functioning well. These machines have had known failure issues in other markets and customers have demanded them to be replaced due to lack of support and confidence in the machine. We have confirmed the failures related to the machines were due to uneducated field technicians that damaged the machines during testing. The machines can be retained, with new AC motors installed and rope grippers to provide unintended car overspeed protection. The cost to replace the AC motor and modify the existing equipment may approach the same cost of replacing the machine with a new geared or gearless alternate. We recommend replacement of the machines if costs to add rope grippers exceed the cost of replacement.

The original GAL MOHL door operators were commonly installed as they were reliable and easy to maintain. Today, there are new “closed loop” door operators that can be retrofitted to this system and used with the existing door equipment. The hoistway door tracks and hangers can be retained. All door rollers, pickup rollers and interlocks should be replaced. The improved “closed loop” door control provides a variable speed drive that can adjust the door motor for potential stack affect with digitally encoded feedback. The “closed loop” control also improves passenger safety by its ability to adjust for door closing force. We recommend replacing the existing operators with new GAL MOVFR harmonic or MOVFE linear operators for all the elevators.

Existing signal fixtures pushbuttons are obsolete. Planning for replacement should also include new hall and car fixtures as well as replacement of the multi-light hall position indicators at the Lobby level. The original design of the hall pushbutton stations are unique to the building. The contractor can investigate retrofitting a newer, more robust pushbutton in the existing hall pushbutton station or replacing them with a matching hall station, to ensure the original design intent is not changed.

The elevator cab interiors are original and in good condition. The cab interior finishes can be retained.

Changes in equipment design and technology have made the existing dispatching system, motor control, and door operation obsolete. Seismic upgrades are required to meet current code requirements when modernizing elevator controllers.

JUDGES’ ELEVATORS 10 AND 11

SUMMARY AND RECOMMENDATIONS

A. GENERAL

During our survey, existing passenger elevator components were checked to determine overall condition and suitability for continued use. In addition, machine room, hoistway, and pit spaces were reviewed for compliance with current codes. This section reviews the results of our equipment survey.

B. EQUIPMENT DISPOSITION

The elevator systems in the building were manufactured and installed by Fujitec America. The existing elevator equipment is in average condition for this vintage of equipment.

Judges’ elevators, Cars 10 and 11:

1. Rated capacity of 3,500 lbs.

2. Travel speed of 700 fpm.

3. Serve 17 landings, Floors B1-16.

4. Installed in 1997

Existing car interiors comply with the Americans with Disabilities Act.

Existing controls are original and were engineered in 1995, and the installation was completed in 1997 by Fujitec America. Parts are still available for the DC 200L machines traction elevators with Fujitec DCD- 301 controls; however, the controller technology is outdated, and the support and technician's knowledge of this product is limited. The machines are in above average condition for the vintage of the equipment.

DC machines with adequate levels of maintenance should last more than 20 years. We recommend using a third-party motor testing company to review the machines in detail for reuse. These machines may be retained for reuse, and upon review of machine testing results; be able to provide reliable service for 20 more years. It is unknown how long Fujitec will continue to provide support on the existing controls. The DC controllers are over 20 years old and will continue to be problematic. Technical support and engineering support is limited. These systems were not installed in the US in large numbers, so the technical capability and resources of the original manufacturer is limited, and capability to support the system by local contractors is more limited.

As an alternative, non-proprietary controls could be specified, however, they will result in an increased initial installation cost of approximately 10%.

In addition to Section 14250, Lerch Bates will provide general Terms and Conditions specification sections for hydraulic elevators. A partial list of those documents include: Instructions to Bidders, Quotation Form, Summary of Work, Alternates, Project Procedures, Submittals, Related Work, and Interim and Long-Term Elevator Maintenance. The bidding community is familiar with the Lerch Bates documents and the tendering process.
