STATEMENT OF OBJECTIVES

Project Number: 1072515

Repair Club Infrastructure, B3008

Prepared December 5, 2019

Forward:

Building 3008 at Whiteman Air Force Base was constructed in the mid 1990’s. The building is utilized as a place of congregation and dining. Orientation, training, celebration, and social gatherings are just some of the many work related events that take place in this building. Because of the many, and varied, events that take place in Building 3008 it is heavily frequented.

Much of the equipment and infrastructure in Building 3008 was installed when the building was initially built, approximately 25 years ago, and has reached the end of its service life. Project Number 1072515 has been conceived, developed, and put forth to repair aging and deteriorated infrastructure at Building

3008; a building more commonly referred to on base as the “Mission’s End Club”.

The succeeding list is a list of objectives targeted for completion through Project Number 1072515. It is the contractor’s responsibility to develop solutions to these objectives.

1.) Replace the HVAC Air Handling Units

The Mission’s End is climate controlled by 8 separate air handlers. These air handlers are all original to the building. In this line item it is the contractor’s responsibility to remove the existing units and replace them with new units. The contractor should make every effort to reuse the existing ductwork that services the building. Ductwork at the interface of the newly installed handling units and the existing ductwork will have to be mated for fit.

In addition to replacing the existing air handling units, it is the contractor’s responsibility to consult with a mechanical design professional to adequately size the air flow of each air handling device. Areas of focused analysis should include, but aren’t limited to, the size of the air handling unit required to provide conditioned air to the bar and a complete analysis of the air pressure fluctuations created by the kitchen exhaust hoods.

The chiller that services the current air handlers was recently installed, and any new equipment will mate up to it. It is a requirement of this scope element that all newly installed air handlers, and HVAC systems, are compatible with and tied directly into the Base’s METASYS monitoring system.

The eight air handling units that feed the Mission’s End Club are all located in the attic. Two mezzanines were constructed to hold these units. New handling units should be configured to fit on the existing infrastructure in place for these units. New units should be arranged and laid out so that future technicians can work on the units with reasonable ease. While unrelated to the function of the air handlers, but in association to their proximity, it is also a requirement of this scope element to replace and upgrade the attic lighting around the air handling units.

2.) Repair and Replace Portions of the Sanitary Sewer Drainage System

Overview of the current conditions: Sanitary drains are largely fed from three sources. These three sources are the kitchen, the bathrooms, and the mechanical room. Sewer drains from the mechanical room feed into a basement level sump-pump that in-turn pumps the water into the main sewer system.

The mechanical room system is working as intended and in no need of repair. The kitchen area is serviced by many drains that penetrate the floor of the kitchen, and emerge into a basement room below the kitchen. In the basement room a network of drain pipes channel the many kitchen drains into one of four drain pipes that exit the basement through the walls of the basement. Attachment #1 shows an overview of this basement drain system. Upon exiting through the basement walls, these four drain branches condense into one 6 inch main line that winds under the floor, picks up restroom waste, and then exits the structure.

The following list details the contractor’s responsibilities to fully satisfy item number two in this statement of objectives.

2a.) Analysis, and service work, has shown the USAF that there is a dip in the three inch sewer line as it exits the basement room under the kitchen. See the circled area in attachment # 2 that approximately denoted this dip. It is the contractor’s responsibility to excavate down to this pipe, and replace the depressed section so that no water “ponds” inside the pipe. All replaced pipe work should be sloped evenly and properly upon replacement to the standards set forth in the national codes (IPC and UPC). It is the contractor’s responsibility to verify this pipe depression, and submit a plan for remedy prior to construction.

2b.) Four waste lines exit the South wall of the basement room underneath the kitchen. These pipes transition from PVC to cast iron where they penetrate the wall. One of these four pipes is split. It is a requirement of this package to replace the pipes in the localized area where they transition through the wall. The split pipe and two other pipe transitions need to be replaced. See attachment #3, the three pipes circled in the attachment represent the three transitions that need to be replaced. Note the scope of this package does not require us to replace the pipe that transitions through the wall and ports to the grease / water separator. It is the contractor’s responsibility to follow all guidelines and codes associated with this scope item. The contractor will be required to seamlessly tie into the existing infrastructure on either side of the proposed work area. When work is completed the contractor will have developed a repair that corrects the split pipe, and ensure that the other two pipes will function properly without fear of failure.

2c.) The basement room has a solitary floor drain to evacuate any ponded water. This scope element directs the contractor to remove, and completely replace this floor drain. The current cast iron drain has reached the end of its service life. The drain’s failures have directly led to structural degradation of the building. For this reason, it is in the contractor’s scope to completely replace both the drain, and the pipe that drains the drain. The contractor will locate the low point of the floor (at or about the current location). The contractor will saw cut the basement floor from the location of the newly installed drain to the basement sump pump pit. This saw cut will be of minimal width necessary to lay a new drain pipe. The contractor should take the most direct route possible from the drain to the sump pump.

Upon saw-cutting a path in the floor for a new drain pipe, the contractor shall excavate as required and install a new drain pipe from the floor drain to the sump pump. The contractor is responsible for removing all debris, back-filling the new drain, casting new portions of the floor, and seamlessly day-lighting the floor drain line into the sump pump basin. See attachment #4 that provides a generalized idea of this work, note this attachment is only a generalization, it is ultimately the contractor’s responsibility to lay-out and design the new floor drain system.

2d.) Certain work task associated with statement of objectives item number two will more than likely require the contractor to cut through the finished floor slab in order to reach and repair portions of the existing sewer system. While it is ultimately the contractors responsibility to develop a system to repair these sub-grade pipes, the probability that any developed system requires the contractor to breach the finished floor is high. This probability is very high in the room between the kitchen and the ballroom, and along the Northeastern wall of the ballroom itself. Should the floor, and attached components, require selective cutting and excavating, it is the contractor’s responsibility to replace all finished floors, walls, and finishes in-kind. Any plan developed by the contractor should make every effort to minimize the amount of invasive dismantling to the current fit and finish.

3.) Remedy sewer gas smell in the Women’s and Men’s restrooms

Overview of the current conditions: The tile floor in the rest rooms is not consistent in slope and grade, subsequently this creates a poor bearing surface for the toilets. The instability of the toilets has led to failures in the wax rings at the interface of the toilets and the floors. The failures in the wax rings has led to the undesirable venting of sewer gas into the localized air.

3a.) It is the contractor’s responsibility to level the floor in the restrooms and ensure that the toilets are mounted consistently and solidly on a new bearing surface. It is the contractor’s responsibility to develop a plan to level the restroom floors whether it be though alterations to the current floor, or removal and replacement of the current floor in both bathrooms. Should replacement of the floor be required, it is the contractor’s responsibility to localize the work to the floor as much as possible; all reasonable efforts should be made to keep the walls and surrounding elements in place as is. Should the floor require replacing, replace in-kind with tile. The primary objective of Statement of Objectives, item number three, is to eliminate the sewer gas odor being omitted at the base of the toilets.

3b.) There are several clean-out caps in the bathroom, it is the contractor’s responsibility to replace and reseal these clean-out covers to a condition that prevents them from emitting sewer gas into the room.

It is the contractor’s responsibility to correct any fit and finish around the caps, as required, to ensure an air tight seal is made at the caps.

3c.) This scope element instructs the contractor to replace components of the bathroom sewer drains that require replacement in order to eliminate the sewer gas odor.

4.) Renovate the Storage Room Behind the Stage

Overview of the current conditions: The storage area behind the stage is a heavily utilized area where equipment is moved in and out. Over time use of this area has caused it to degrade. The buildings

Comm cabinet is located in this storage room and is often hit and or bumped as material is moved in and out.

4a.) Demolish all failing and damaged finishes to the storage room. Finishes to be removed include, but aren’t limited to: ceiling tiles, trim, carpet, flooring, and light fixtures.

4b.) Design and complete a renovation of the storage room. This renovation should incorporate a protective element to the Comm cabinet without moving the Comm cabinet.

4c.) The completed renovation, and finishes, should transition smoothly into the main ballroom; any work required to make this complete architectural transition into the ballroom is the responsibility of the contractor.

5.) Upgrades to the Hot Water Heating System

Replace the hot water tank, the hot water re-heat unit, and the hot water boiler. All three of these units are currently side-by-side in the mechanical room. In addition to replacing these components, it is the contractor’s responsibility to replace any pipe work that immediately leads up to, and plumbs into these units. Pipe work that is not in the immediate vicinity of these units, and does not directly branch off into these units, is not part of the scope of this project. The contractor should replace these units without alterations to the surrounding walls or finish floor slab. It is the contractor’s responsibility to size the replacement units appropriately; the newly installed units should meet or exceed the level of output the currently installed units produce. Attachments #5 and #6 show pictures of the current units to replace.

6.) Replace Lights in the Basement Room Under the Kitchen

Replace the light fixtures in the basement room underneath the kitchen. This scope element calls for replacement of the light fixtures using the same circuitry that is in place. New light fixtures are to meet, or exceed, the luminosity of the current fixtures. New light fixtures should utilize LED illumination, not incandescent or florescent. While the existing circuitry should be used to power the new lights, some replacement of boxes, splices, and conduit may be required to complete this scope element.

7.) Replace and Repair Six Structural Load Bearing Columns in the Basement

Overview of the current conditions: Flooding over time, and compromised drains, have caused six columns in the basement to deteriorate at their base. Attachment #7 shows where these 6 columns are located, they are called out as A,B,C,D,E, and F

7a.) Analyze and design a repair / replacement for the compromised columns utilizing a qualified professional. The contractor will be required to show that a licensed engineer has reviewed any submitted plan. Any column splicing and replacing should be isolated to the basement room where the corrosion has occurred; the sections of column above the kitchen floor are not to be altered as part of this scope. The contractor is to follow all loads set forth by the most current publications of the IBC and

ASCE 7.

7b.) Replace / repair the 6 compromised columns.

7c.) Any localized cutting and excavating to the basement floor, done to access the column footings, shall be replaced in kind by the contractor.

7d.) It is the contractor’s responsibility to remove and dispose of all replaced material.

7e.) It is the contractor’s responsibility to devise and implement a shoring plan for the structure the six compromised columns support while this work is being completed. This shoring plan should be submitted with the column design plans.

7f.) It is the contractor’s responsibility to replace “in-kind” any part of the structure they remove, take-down, or alter while completing the statement of objectives item number 7.

8.) Replace and Add Valves to the HVAC Water Heating System

Overview of the current conditions: Recently the hot and cold water systems feeding the HVAC equipment were upgraded. The hot water supply requires the addition, and replacement, of six valves localized to the area of the hot water pumps.

8a.) There are two triple duty valves on the discharge end of the hot water units that feed the HVAC equipment. These triple duty valves are inline, and directly after, the pumps that pressurize the hot water. It is a requirement of this job to replace both of these valves with “in-kind” gate valves. The picture in Attachment #8 shows these valves, they are the green colored valves.

8b.) Replace two isolation valves to the hot water system. These isolation valves are located directly before the two pumps that pressurize the hot water system. These valves can be either gate or butterfly valves.

8c.) Add two isolation valves to the hot water system. These isolation valves are to be placed after water has moved through the triple duty valves. One isolation valve should be added to each line as the lines emerge from the triple duty valves. These valves can be either gate or butterfly valves.

8d.) It is a requirement of this project to cleanly and neatly splice into the existing mechanical system.

The contractor is responsible for adding and-or replacing any localized connections that result from adding and replacing these valves. Only piping and plumbing that directly ties into these valves is to be altered as a result of this scope element. Attachment #9 shows a picture of the localized area.

9.) Design: The contractor is solely responsible for the design of all of the repairs outlined in this statement of objectives. The contractor is prohibited from altering the intent of the building or the building’s systems. The contractor however can propose alternative design configurations to the existing layout of the building’s structural and mechanical systems in order to complete the prescribed work in the

Statement of Objectives. Any proposed alterations to the structural or mechanical systems are subject to government approval.

10.) Contract agreements: All design and construction will be in accordance with base contract agreements.

11.) Design Criteria: The project shall be designed in accordance with the latest codes and criteria as of the date listed at the top of this page to include, but is not limited to: the Whiteman Design Compatibility Standards, energy conservation considerations, and all appropriate codes (i.e., Uniform Building Code, National Fire Protection Code, National Electrical Code, National Plumbing code, and other applicable DOD and Air Force regulations, Manuals, Unified Facilities Criteria, Air Force Specific Facilities Criteria, and Engineering Technical Letters).

12.) Materials and Services Furnished by the Government: On request, the Government will furnish blueprints of available as-built drawings that are pertinent to the facilities involved. However, these drawings are not warranted to show conditions as they actually exist. The designer shall verify (by field investigation) information shown on the as-built drawings (which is relevant to the project) for accuracy to ensure a quality-designed project.

13.) As Builts: Three copies of completed construction drawings (as-builts) on CD or DVD will be required upon completion of this project that includes high resolution pdf’s and AutoCAD 2015 drawings. In addition, digital photos of the area before project start and after project completion will be supplied.
