1010 Lamar Elevator Modernization for the Office of the County Engineer

SCOPE

The intention of this Harris County Competitive Sealed Proposal (CSP) is to solicit offers for the turnkey modernization of five (5) passenger traction elevators serving eighteen (18) floors and one (1) freight traction elevator serving twenty-one (21) floors at 1010 Lamar Street (Harris County Annex Forty-Eight (48)) in Houston, Texas. This project will be executed in two (2) phases: Phase I (“East Bank”) comprising two (2) passenger cars and one (1) freight car, followed by Phase II (“West Bank”) comprising three (3) passenger cars. During the modernization of one (1) bank of elevators, the other bank must remain fully operational and accessible to building occupants and staff at all times; under no circumstances shall work on one (1) bank interfere with or impact the normal, continuous operation of the other bank.

Any work that may pose a risk of disruption to the active elevators must be scheduled in advance and mitigated to ensure uninterrupted service. The scope of work includes upgrading or replacing major elevator components with non-proprietary equipment – including new microprocessor-based controllers, hoisting machines and ropes, automatic door operators, and the installation of emergency egress devices and pit flood alarm systems. The modernization work shall tie into the building’s existing fire alarm panel and existing power systems, and all new equipment shall communicate seamlessly with each other and any remaining elevator systems in the building.

All work performed and equipment installed shall comply with or exceed the latest applicable codes and standards, including the American Society of Mechanical Engineers (ASME) A17.1 (Safety Code for Elevators and Escalators), ASME A17.2 (Inspector’s Manual), ASME A17.5 (Elevator and Escalator Electrical Equipment), the Americans with Disabilities Act (ADA) Accessibility Guidelines (ADAAG) and Texas Accessibility Standards (TAS), National Fire Protection Association (NFPA) 70 (National Electrical Code), NFPA 101 (Life Safety Code), and all other state and local codes and ordinances.

The goal of this project is to enhance elevator safety, performance, energy efficiency, reliability, and flexibility, while reducing long-term operational costs and avoiding vendor lock-in by using non-proprietary, open-architecture systems. Current performance and carrying capacity of each elevator shall not be reduced or degraded as a result of the modernization. The Harris County Office of the County Engineer (OCE) shall have final decision-making authority on any design or engineering changes related to this project, including the configuration of elevator machine rooms or associated building modifications.

TECHNICAL SPECIFICATIONS – ELEVATOR EQUIPMENT AND SYSTEMS

All new components shall be non-proprietary to ensure open maintenance access and long-term serviceability by multiple vendors. The following technical requirements apply to the major systems and components of the elevators being modernized:

• Traction Machines and Hoist Ropes: Provide and install new alternating current (AC) gearless traction machines and wire ropes (hoist cables) for each elevator as needed to replace the existing equipment. Each new machine and rope set shall be sized and rated for the specific elevator’s duty, including capacity, speed, and travel distance. New machines shall include all required drive sheaves, isolation pads, bedplates, and safety guards, and be compatible with the existing shaft and car arrangements. The new hoisting machines must deliver performance equal to or better than the originals in terms of elevator speed, ride quality, and capacity. The vendor shall verify that the building’s structural support and existing machine room layout are sufficient for the new equipment; any required modifications to accommodate the new machines (such as beams or supports) shall be included in the proposal.

• Controllers and Drive Systems: Replace all existing elevator controllers with new non-proprietary, microprocessor-based controllers from a recognized independent manufacturer (e.g. Motion Control Engineering, SmartRise, GAL Manufacturing, Pixel, or equal). Each controller shall be Underwriters Laboratories (UL) listed and provide modern operational features including on-board diagnostics (with fault logging and plain-English messages), Firefighters’ Emergency Operation (FEO, Phase I recall and Phase II), and automatic emergency lowering or standby power operation in case of building power failure. Controllers must be fully integrated with all new and retained elevator components and tuned to ensure smooth, efficient ride performance with improved acceleration, deceleration, and leveling accuracy under all load conditions.

The vendor shall provide all documentation, diagnostic tools, and software for the controllers at project turnover, including two (2) complete sets of as-built wiring diagrams, programming and troubleshooting manuals, and any software or special programming keys needed to access and adjust all controller functions.

No special passwords or proprietary dongles shall be required to service or adjust the controllers – the delivered system must be fully open and accessible to the Owner’s maintenance provider. Each new elevator drive system (motor drive unit) shall be solid-state and energy-efficient. If applicable, a soft-start motor starter or variable-frequency drive (VFD) shall be provided to minimize inrush currents and reduce mechanical and electrical stress during starting and stopping. All new wiring in the machine rooms and hoistways (traveling cables, hoistway wiring, control wiring, etc.) shall be replaced with new code-compliant wiring and conduit throughout. This includes installing a new, lockable, fused mainline disconnect switch in each machine room that meets code requirements and can be secured to prevent unauthorized energization. All new traveling cables shall be flexible, flame-retardant, properly supported, and include at least ten (10) percent spare conductors for future needs.

• Door Equipment (Operators and Entrances): Install new non-proprietary door operators on all elevators for smooth, quiet door operation and reliable performance. Door operators shall be capable of variable speed control and be fully compatible with the new control system and existing door hardware. The vendor shall replace or refurbish door tracks, hangers, rollers, and interlocks as needed to ensure each door operates safely and efficiently, with minimal noise and smooth motion. Hoistway door panels and frames may be retained if they are in good condition; however, they must be cleaned, refinished, or replaced as necessary to achieve a like-new appearance and performance. New sill plates shall be installed at all entrances where existing sills are worn or damaged, properly anchored and grouted flush with the adjacent flooring.

• Elevator Fixtures (Hall Stations and COP): Hall call stations at all elevator lobbies shall be replaced with new ADA-compliant, vandal-resistant stainless-steel hall stations. Each hall station shall include illuminated “Up” and “Down” call buttons with raised text and Grade 2 Braille, and shall be installed at heights and locations meeting ADA/TAS requirements. The Car Operating Panels (COPs) in each elevator car shall be replaced with new non-proprietary, heavy-duty, stainless-steel COPs that meet ADA and TAS requirements. Each COP shall include all standard features and fixtures, including: lighted floor-selection buttons with tactile markings and Braille; Door Open and Door Close buttons; an alarm button and emergency stop (if applicable); an in-car digital position indicator and audible arrival/floor announcements;

an Independent Service key switch; fan and light key switches; and any other controls or displays required by code. Each COP shall also include a firefighters’ Phase II key switch (keyed Firefighters Emergency Operation Key 1 (FEOK-1)) for emergency recall operation, as well as a dedicated indicator light for the new pit flood alarm system (to alert if water is detected in the pit). In addition, provide and integrate a new hands-free emergency two-way communication system in each car, utilizing a Call Over Secure Serial (COSS) 4G/5G cellular communicator (or equivalent), fully compliant with ASME A17.1 and Texas code requirements. The emergency telephone shall include an in-car call button with Braille and visual call acknowledgement, and be programmable to automatically dial a monitoring service or security desk, providing the elevator identification and location. New brushed stainless-steel handrails shall be installed on the car interiors as required (at least one (1) handrail on each cab wall), mounted at ADA-compliant height and clearance.

• Door Protection System: Install modern door protection devices on all elevators to ensure passenger safety.

Each elevator door shall be furnished with a full-height, two-dimensional infrared light curtain system which detects persons or objects in the doorway and prevents door closure if the doorway is obstructed. In addition, provide a door-mounted visual indicator system (such as Janus Panachrome+ or equivalent) that gives a red/green signal to passengers at the landing – showing a red light when doors are about to close and green when it is safe to enter or exit. The door protection system shall cause doors to automatically reverse if an obstruction is detected, in full compliance with ASME A17.1 and ADA requirements.

• Cab Interior (Freight Elevator) and Lighting: Modernize the freight elevator cab interior as part of this project. The freight cab refurbishment shall include new durable wall panels, protective bumper rails, a non-slip floor, and replacement of the existing ceiling or lighting with new energy-efficient LED lighting that meets the minimum illumination levels required by code. The design and materials for the freight cab interior upgrade will be selected by Harris County (from standard options) and installed by a specialty cab interior subcontractor of the County’s choosing, coordinated by the elevator vendor. A cash allowance of $40,000.00 (Forty Thousand Dollars) shall be included in the proposal for the freight elevator cab interior rehabilitation; this allowance will be used by the County to cover the cost of the separate cab interior contractor, and the elevator vendor shall facilitate that work including scheduling and providing access as needed. (No modernization of the passenger elevator cab finishes is required under this scope.) All new or refurbished cab finishes and fixtures must meet or exceed ASME A17.1, ADAAG/TAS, and fire code requirements for smoke and flame spread.

• Pit Flood Alarm System: Furnish and install a new water-intrusion detection and alarm system for all six

(6) elevator pits. Each elevator pit shall be equipped with a robust water sensor (float switch or similar) mounted at an appropriate elevation to detect rising water before it reaches critical levels. The system shall tie into the new elevator controls such that upon water detection, the affected elevator is immediately prevented from traveling to the lowest landing, and an audible and visual alarm is activated to alert building personnel. In addition, each new COP shall include an indicator light to signal when a pit flood condition is detected in that elevator. The pit flood alarm system must meet all applicable code requirements for elevator safety and flood detection.

• Emergency Power Operation and Automatic Lowering: Ensure that the modernized elevators are integrated with the building’s existing emergency power generator (if available) for operation during power outages. If a standby generator is not available or cannot be interfaced, provide a self-contained emergency battery lowering device for each elevator to automatically lower the car to a safe landing and open the doors in the event of an extended loss of normal power. The emergency lowering/battery backup system shall engage after a power failure of more than a few seconds and operate each elevator’s brake and door operator to allow passenger egress at the nearest floor. Each such system must be capable of safely handling a fully loaded car and include a maintenance-free battery with a minimum four (4)-year life, plus an automatic self-testing feature to ensure functionality. Emergency power and lowering systems shall comply with all local requirements, and if integrated with a generator, the vendor shall test the elevators on emergency power to validate proper interfacing and operation.

• Firefighters’ Emergency Operation (FEO): The new control systems shall include FEO in full compliance with ASME A17.1 and NFPA 101. This includes Phase I Emergency Recall (automatically returning elevators to a designated recall floor upon activation of a fire alarm signal) and Phase II Emergency In-Car Operation (allowing firefighters to manually control the elevators from within the car using the FEOK-1 key). The vendor is responsible for all necessary interfaces to the building’s existing fire alarm system to achieve FEO functionality, and must coordinate and conduct a successful integrated fire alarm/elevator recall test as part of the final acceptance testing. All control programs, sensors, wiring, and signaling devices must function as required by code for firefighter service.

• Additional Safety Features: Install or upgrade all other safety systems as required to meet current codes and Harris County’s standards. This includes ensuring proper functioning of emergency stop switches, alarm bells, car door restrictors, final limit switches, buffer switches, safety brakes, and other required safety devices on each elevator. Any existing devices that are not code-compliant or not in excellent operating condition shall be replaced or upgraded as part of the project (this may include items such as governor tension weights, safety linkages, etc., as applicable). All new safety components must be compatible with the upgraded systems and meet the requirements of ASME A17.1 and any stricter local safety standards.

Equipment to be Retained and Reused In general, Harris County prefers to retain and reuse existing elevator components that are in good condition and code-compliant to maximize cost efficiency. The OCE shall have the exclusive authority to decide which existing components are to remain in place or be salvaged for future use, and which are to be replaced or discarded. Based on the project scope and current assessments, the following existing equipment is slated to be retained and integrated into the modernized systems (unless otherwise determined by the OCE):

• Existing buffers (bottom-of-hoistway safety buffers)

• Existing guide rails in each elevator hoistway (to be cleaned, realigned, and reused)

• Existing cab flooring (passenger elevators; existing floor finishes to remain)

• Existing car platforms and enclosures (shells)

• Existing pit ladders in each elevator pit

• Existing pit light fixtures in each elevator pit

• Existing cartop inspection stations, if the new control systems are compatible with the existing units

• Existing door sills at each landing

Note: The vendor shall take care to protect all components designated for retention. If any of the above items are found to be unusable or not in code compliance during the project, the vendor must notify the County’s representative for direction. Harris County reserves the right to adjust the list of retained equipment based on further inspections; any additions or removals will be communicated in writing. All items not specifically listed for retention shall be assumed to be removed and replaced as part of this modernization.

Roof Hatch Installation Vendor shall engage and coordinate a qualified third-party contractor to design and install a new roof access hatch above the 1010 Lamar elevator machine room, which will facilitate the safe removal and replacement of the heavy hoisting machines. All costs for this hatch installation (including materials, labor, permits, and any required engineering) shall be included in the vendor’s proposal. The new machine room roof hatch must be appropriately sized to accommodate the hoisting equipment, lockable from the inside for security, and fully watertight to maintain the building’s weatherproof integrity. The hatch and its installation shall be permanent and comply with all applicable building codes and safety regulations, including structural support, fire-resistance/rated construction (if required), and any necessary fall protection or guardrails. The vendor and its chosen subcontractor shall obtain any permits and inspections required for the roof hatch installation, and all such work shall be performed to the same standards of quality and safety as the main elevator scope. The installation of the hatch shall be scheduled and completed in a timeframe that ensures it is ready in advance of lifting operations for the elevator equipment, so as not to delay the overall project.

The vendor’s responsibilities for the roof hatch work include: selecting and managing the third-party construction firm (with Harris County’s approval), overseeing the hatch installation to ensure it meets all specifications and codes, coordinating access and scheduling with building management to minimize disruption, and verifying that the finished hatch is acceptable to the County. The third-party contractor will be responsible for executing the roof cut and hatch installation, providing all required materials and labor, maintaining a safe and clean work site, and obtaining all necessary permits and approvals. The completed roof hatch must pass all required inspections and performance tests (e.g. water leak test) and be formally accepted by Harris County as part of the overall project’s final acceptance.

Deliverables specific to the roof hatch portion (to be provided by the vendor on behalf of the third-party): as-built drawings and specifications for the installed hatch, warranty documentation covering the hatch materials and workmanship (minimum one (1)-year warranty required), and copies of all permits, inspection certificates, and code compliance verifications related to the hatch installation. The roof hatch and installation shall be warranted for a period of not less than one (1) year from Final Acceptance, during which any leakage, defect, or operational issues shall be corrected by the responsible subcontractor at no cost to the County.
