1. Executive Summary

1.A. Project Scope of Work The Amarillo VA Health Care System has two existing elevators cars original to Building 4 built between 1938 to early 1940’s and one existing elevator car which was constructed in the VA’s 1939 Building 7 in 1989 (Design Date). These Elevators are beyond their life span, although they may not be the same ones from the 1940’s for Building 4, there are no records of any of these elevators being replaced. Building 4’s elevators receive a steady traffic 24/7 while transporting employees and supplies from between the 1st and 2nd floor. The Freight Elevator was part of the original design of the building and has a key control with top and bottom Bi-Fold doors with a capacity of 4,500 lbs. and an older LIFELINES Emergency Phone inside a panel. The Passenger Elevator is a 3,500 lbs. passenger elevator, not shown in the original 1938 drawings, but appears in the 1950’s drawings as an existing elevator. Building 7’s elevator receives frequent traffic from 0700 to 1700 while transporting IT Staff and carts of computer supplies serving three floors from the basement to the 2nd floor. This design is to replace and upgrade the 2,000 lbs. This design is to replace and upgrade both elevators along with their associated Controls, Electrical components, Mechanical components, and Elevator Equipment to the most up to date. This project will correct the deficiencies in the existing elevators and bring them to modern technology.

1. See specification 01 35 26 – Safety Requirements for specific ICRA class requirements.

2. TYPE OF CONSTRUCTION PROJECT ACTIVITY

A. Type C construction is applicable to this project.

3. PATIENT RISK GROUP

A. Dining, kitchen, and EVS are categorized as a high-risk group.

4. CLASS OF PRECAUTIONS

A. With Type C construction activity taking place in high-risk areas of the campus, Class IV ICRA requirements must be met for the entire duration of this project. At any point, the COR may halt work until satisfactory compliance of each requirement has been met.

5. TEMPORARY BARRIERS AND DOORS

A. 3mm sheet plastic and zippers shall only be used to contain dust while constructing short-term and long-term temporary barriers. All temporary barriers shall be constructed before any demolition or work begins and shall remain installed throughout the duration of project work and clean-up.

B. Long-term and short-term temporary barriers shall be constructed of metal studs and 5/8” Type ‘X’ gypsum board on both sides, taped at all joints. Short-term barriers shall only be installed while active wall and/or door infill is taking place; once the applicable work is completed, the short-term barriers will be taken down. Long-term barriers, however, shall remain throughout the entire duration of construction work, see ICRA sheets AS101 to AS106.

C. An ante room is also required as an interim space between the medical facility and the construction zone. This area will be used as the main entrance into the construction zone.

2.

2.A. General

1. The purpose of this project is to replace a total of three elevator cars, along with their associated controls and equipment, at the Thomas E. Creek Department of Veterans Affairs Medical Center in Amarillo, Texas. Two of the three elevators are located in Building 4 - Dining Hall, while one is located in Building 7 – Information Technology (OI&T). All three elevators are out of date and ready to be replaced;

this project will correct the deficiencies regarding the existing elevators and bring them up to date with modern technology and current code requirements.

2.B. Design Parameters & Reference Data:

2.C. Existing Architectural Conditions

1. Building 4 was built in 1938 through 1940 and there has been no record of the freight or passenger elevator being replaced, though that does not necessarily mean they have not been. Both Building 4 elevators are used frequently - 24 hours a day, 7 days a week, transporting staff and supplies. The existing freight elevator has a capacity of 4,500 lbs., while the passenger elevator has a capacity of 3,500 lbs.; these two elevators span two floors (level 1 and level 2). The passenger elevator shaft is 7'3-11/16" wide x 8'1-1/2" deep (from door) on the interior and constructed from metal studs and drywall. The freight elevator shaft is 8’11” wide x 8’10” deep (from door) on the interior and constructed from metal studs and drywall.

2. Building 7 was built in 1939, though the passenger elevator to be replaced was constructed in 1989. This elevator also receives heavy traffic - primarily from 7 AM to 5 PM, transporting staff and IT related carts and supplies. It has an existing capacity of 2,000 lbs. and spans three floors (basement, level 1, and level 2). The shaft is 7'4-3/16" wide x 6'0-1/8" deep (from door) on the interior and constructed from CMU.

2.D. New Architectural Work:

1. DEMOLITION

A. Existing elevator cab to be removed and replaced.

2. NEW CONSTRUCTION

A. New elevator cab to be installed. Additionally, all safety features are to be brought up to code and function with the facilities current systems. Unless otherwise directed, this project shall comply with all applicable codes, VA program guides, design guides, requirements, and standards.

2.E. Interior Design Narrative

1. Interior design will match finishes present in the corridor and adjacent spaces. All material and finish decisions will be approved by the VA interior design prior to installation.

3. Structural Design

3.A. General

1. Building 4 freight elevator is 4500 pounds with the passenger elevator is currently 3,500 pounds.

Building 7 passenger elevator is currently at 2,000 pounds with all three being modernized.

DAV Project # 90071 Page 6 of 11 July 22, 2022

3.B. Design Loads

1. Live Loads- Building 4 freight elevator is 4500lb and will remain 4500lbs. Building 4 passenger elevator is 3500 lbs and will remain 3500 lbs.. Building 7 passenger elevator is being 2000 lbs and will remain 2000 lbs.

2. Wind Loads - The design wind speed is 118 miles per hour with Exposure C in accordance with ASCE 7-

16. The project is all on the interior of the building so wind load will not affect the elevator.

3. Snow Loads- The ground snow load at this site is 15 psf. The project is all on the interior of the building so snow load will not affect the elevator.

4. Seismic Loads- The Short-period Spectral Response Acceleration is 0.195g and the 1-Second Spectral Response Acceleration is 0.045g. Per ASCE 7-16, the Seismic Occupancy Category is IV. The Soil Site Class is assumed to be Class D. These parameters result in a Seismic Design Category of C for the Medical Center. The 2018 IEBC Section 806.3 specifies that if the seismic demand-capacity ratio increases by more than 10% above the original construction, a seismic evaluation must be performed on the existing structure. The seismic demand on the elevator rails includes loads from the car weight, plunger weight and partial live load. The dead loads and live load of the new elevator system will remain under a 10% increase, therefore the existing rails and connections will not need to be replaced.

3.C. Existing Elevator Structure

1. The hoist beams of the elevator shaft will need to be checked for the increased weight of elevator cars if the car weight increases by more than 5% PER 2018 IEBC SECTION 806.2.

2. Special Inspections - Special inspections, testing, and observations are as required per IBC Chapter 17 for structural steel.

4. Mechanical Base of Design

4.A. General The scope of this project is the upgrade of the 3 elevator systems. Two located in building 4, and 1 located in building 7, with their corresponding elevator maintenance rooms. With the addition of new equipment in these rooms, new cooling systems will need to be added to alleviate the new heat loads. To avoid interrupting the existing HVAC system, mini splits will be added to each of the rooms with 5/8” piping running from the maintenance rooms to the nearest exterior wall where the outside portion of the units will be placed.

4.B. Design Parameters & Reference Data

1. International Building Code, 2018

2. Department of Veteran Affairs: HVAC Design Manual, March 2021

4.C. Existing Conditions

1. Heating, Ventilating and Air Conditioning (Division 23):

2. Freight elevator in building 4 is a hydraulic lift elevator to operate the 4,500 pounds elevator. There is a 50 hp motor that drives the hydraulics. The hydraulic lift motor is located outside the elevator shaft and appears to be cooled with the central building air.

DAV Project # 90071 Page 7 of 11 July 22, 2022

3. The passenger elevator in building 4 is a hydraulic life that is rated to operate the current 3,500 pounds elevator. The hydraulic lift motor is located outside the elevator shaft and appears to be cooled with the central building air.

4. The elevator in building 7 is a Montgomary hydraulic lift elevator that is rated for 2,000 pounds that is operated by a 20 hp motor. The elevator is maintained by Thyssenkrupp.

4.D. New Systems and Adjustments:

1. Demolish the outdated and broken existing fan coil unit for the Freight elevator in Building 4, along with the hot and cold-water piping and condensate. This system will be replaced with a mini-split system with the condenser unit located on the northwest exterior wall, with piping connected to the internal fan coil unit located inside the space. This will be a 1-ton unit to account for the large heat loads of the equipment and lack of insulation in the space.

2. The mechanical room on the first floor of building 4 associated with that passenger elevator has no existing HVAC system in place. To meet the VA heating and cooling requirements, a new mini-split system will be installed. This unit will have a condensing unit on the southeast exterior wall of the first floor with piping going through the ceiling to a ductless wall mounted fan coil located in the mechanical room.

3. Building 7 has existing supply and exhaust diffusers hooked up to the main duct system in the building, that is operational, this system will need to be rebalanced to meet the requirements dictated by the VA.

5. Electrical Design

5.A. General The 2 existing elevators in building 4 and 1 elevator in building 7 has approached the end of their useful life and are need of replacement. For the electrical scope, all electrical components of the elevator shall be replaced in their entirety.

2. The elevator controls design is based off the Motion Control Engineering Motion 2000 for Hydraulic Elevator Control unit. A similar control unit is acceptable for installation with similar specifications.

9. Modernization Plans

9.A. General The three elevators will need to be modernized to support current and future operations within the Amarillo Veterans Affairs Medical System. The Mechanical, Electrical, Plumbing and Fire/life safety will need to be brought up to code to ensure operation over the life span of the elevators.

9.B. Modernization Objectives

1. In our judgment, a comprehensive elevator modernization at the VA Medical Center Building 4 & 7 should consider the following objectives:

A. Improved system reliability.

B. Improved stopping accuracy and ride quality.

C. Improved door operation.

D. Compliance with current Fire Recall Requirements.

E. Compliance to the Americans with Disabilities Act.

F. Compliance with existing elevator and building Code requirements.

G. Improved aesthetics for building tenants.

9.C. Modernization Scope:

1. Demolish and replace the cab of the elevator, the rails and floor base will remain.

2. Demolish and replace the hydraulic lifts with associated components to include the motors of the elevators.

3. Replace the control of each elevator to allow for smooth operation.

4. Replace all associated electrical components to support the elevator.

5. Install new mini splits for both of the elevators in building 4 to account for the elevator equipment heat loads.

6. Balance the air for the elevator in building 7 to ensure proper airflow.

7. Install new fire alarm system in each elevator to ensure it is to code.

8. Install sub pumps in the bottom of each elevator shaft to meditate water and separate hydraulic fluid

DAV Project # 90071 Page 12 of 11 July 22, 2022

10. Conclusion:

1. The elevators are past their life span and need to be modernized to continue to support their respective buildings current operations.

2. Increasing the capacity of the elevators at this time requires the elevator shafts to be expanded to allow for greater floor space within the elevator compartment. The floor space of the elevators is directly related to the capacity of the elevator.

3. Replacing the supporting MEPS decreases the chance of short-term future disruptions.

4. Addressing the know issues with the elevators mechanical rooms allows for a safer working environment well installation of the HVAC system can lead to reduce strain on the elevator motor.

11. Recommendations:

It is recommended to implement the modernized scope within this document for the elevators in buildings four and seven to allow for continues future operation. This is a replacement of the cab, with the existing rails and floor base remaining as they are of solid construction and there is no need to replace them nor will it extend the longevity of the elevator system. Final documents should include any scope and contractual modifications required by ownership.

To secure the most competitive prices, recommend that bid documents include a Five-Year Maintenance specification for pricing by all bidders.
