2.0 Project Description

2.1 General Description

Scope

This project involves repair and modernization to B528 which houses 319th Operations Support

Squadron Airfield Management and Weather Element. The last significant renovation/addition occurred in 2000, and all major building systems are in need of significant repair or replacement.

Foss Architecture + Interiors performed both a facility assessment and space planning study to evaluate existing building systems conditions and utilization, the results of which are contained in this report.

Function

Airfield Management and Weather Element both provide direct support to airfield activities and aircraft arriving to, and exiting from, the Base. Airfield Management requires direct visual, pedestrian, and vehicular airfield access for maintenance and management. Weather Element provides both visual and electronic monitoring of weather conditions as related to the Base, airfield, and surrounding region. Electronic connection to monitoring equipment located at airfield and face-to-face support for aircraft personnel is required.

Airfield Management is programmed for 11 total personnel housed largely in open office workstations, along with support facilities for flight planning, training, and aircrew lounge. A

Distinguished Visitor (DV) lounge under Wing Protocol management is required to be located in

B528 for direct airfield access.

Weather Element is programmed for nine personnel in a combination of private office and open office workstations. Some personnel provide direct support to aircraft personnel. A training room and a secured communications/storage environment are required.

Airfield Management and Weather Element are 24-hour operations. At times, inclement weather and travel conditions prevent personnel from leaving Base and facilities to accommodate overnight stays are desired.

Site

B528 is located on the western edge of the Base along Eielson Street, and between Steen Blvd.

and Road 16. The location is adjacent to the airfield and is on the flight-line security perimeter.

Criteria in AFI 31-101 Integrated Defense will apply.

A large parking lot is located east of, and directly adjacent to, the building has been maintained in good condition and sized adequately to serve B528. A porte cochere on the south end of B528, adjacent to the DV lounge provides covered vehicular access for pick-up and drop-off.

See Appendix Figure A-1, Vicinity Map, for location of the project site. See Appendix Figure

A-2, Project Site Map, which illustrates the project site location and surrounding area.

2.2 Current Situation

The existing facility functions largely as required and desired by Airfield Management and

Weather Element. Minor functional improvements have been identified, including creation of and Aircrew lounge separate from other AM functions, creation of a toilet/shower and cot space for overnight accommodations, and right-sizing of Weather SIPR functions. Increase in

Mechanical space will allow for improved and centralized mechanical systems.

General Construction Existing Conditions:

B528 is one of the original Base structures remaining, originally constructed in 1955 and has been subject to numerous repair/renovation projects, the most significant occurring in 2000 which included substantial interior renovation, a small addition and exterior wall finish repair.

B529 is the original OSS tower structure connected to B528 which has been decommissioned and the cab removed.

Foss Architecture + Interiors, along with civil, mechanical, and electrical consultants performed a facility assessment in 2020 to evaluate building systems conditions along with space utilization. Report is included in Appendix C.

Exterior cladding consists of thin-brick and exterior insulation and finish system (EIFS) installed in the 2000 renovation. In many areas the thin-brick is failing and delaminating from the substructure. Falling bricks potentially create a hazard for personnel at the building entrances, and roof panels have been damaged at higher elevations.

The metal standing seam roof system was added as part of the 2000 renovation, and its condition was evaluated in 2017. Roof appears to be in good condition.

Aluminum-clad wood windows installed in 1988 are in poor conditions and in need of replacement. Exterior hollow metal and aluminum entrances are in fair-to-good condition and in need of minor maintenance. Glazing does not meet current minimum anti-terrorism standards.

Interior doors are a mix of ages including those replaced in 2000 (north end) and other original to the building (1958 & 1963).

Interior finishes are in fair-to-good condition, though dated in many areas. Flooring tile, paint and vinyl wall finishes, suspended ACT ceiling tile and wood casework are all in need of refresh or replacement to repair worn finishes, update interiors and provide consistent appearance throughout.

B528 meets most ABA accessibility requirements, with some deficiencies noted including:

• Most doors have knob-style hardware in lieu of levers.

• DV Lounge is not wheelchair accessible and kitchenette lacks recommended clearances.

Toilet room lacks grab bars.

• Current reception desk does not have an accessible transaction counter.

Mechanical Existing Conditions:

The heating system for the building is split in half and is served by two separate boiler plants.

Each consists of a Gas Fired Fulton Pulse Combustion Boilers, 500 MBH. Multiple inline pumps are used to serve different piping loops in the building. There is no redundancy built into the system so if one boiler or pump fails there is no heat for the area of the building that it serves. It was also reported that the boilers are undersized and cannot match the heating demand of the building. Exterior rooms have fin tube radiation, vestibules and mechanical/electrical spaces have hot water unit heaters, and hot water reheats are installed in VAVs in ductwork to provide primary zone level heating.

Indoor air handling units provide the ventilation and air distribution for the building. The unit serving the north portion of the building (AHU-2) and associated condensing unit are past their service life and should be replaced. Outside air and relief air is handled through roof hoods and wall louvers. The newer air handling unit (AHU-1) does not have a heating coil and the mixed air temperature gets bellow design temperature during extreme low outside air temperatures. It is believed that the outside air being brought into the building is limited to keep air temperatures

up. No airflow measuring stations installed to verify ventilation airflow.

The controls in the building are a mix of analog and digital thermostats. The system is approaching the end of its service life for all components. Controllers, thermostats, and programming need to be updated per staff as they do not function properly.

Domestic hot water for the building is broken up between the north and south half similar to other systems. Hot water is generated through electric water heaters with the North side water heater being in good condition, but the South side water heater is at the end of its service life and should be replaced. Plumbing fixtures are in good condition.

No fire protection sprinkler system currently installed in building. Would need to be reviewed if fire sprinkler is required to be added if new work occurs in building.

Electrical Existing Conditions:

The building electrical systems are mostly original and approaching end of expected life expectancy. Electrical panels in the main electrical room are newer, likely replaced in the last 5 years, and one panel in the corridor is older (20+ years) and should be replaced. Electrical outlets appear to be in good condition, although replacement of outlets and covers should be considered for aesthetics.

Lighting fixtures are fluorescent tube fixtures, ballasts are reaching end of expected life and bulb replacement or LED retrofit is not cost effective. Lighting controls are switched: automatic lighting controls are recommended, which will reduce energy consumption. Emergency egress signage and illuminate should be replaced.

Specific data requirements need to be evaluated, although it appears deficiencies exist in present condition. Significant upgrades to the existing infrastructure may be more expensive than a new system based on owner specifications.

Fire alarm detection and annunciation is older, portions of the building is alarmed with metal percussion bells. A new fire alarm system is recommended. Building access and camera systems should be updated concurrently with other building upgrades.

2.3 Impact if Not Provided

Not replacing exterior thin-brick cladding will result in continued deterioration and delamination creating hazards for personnel and other surfaces due to falling debris, along with exposure of building elements to weather and compromising weather-tightness and energy performance. Not replacing windows will result in continued deterioration, energy performance and weather infiltration.

Not replacing interior finishes will result in deterioration and wear of floor, wall and ceiling finishes and continued outdated appearance. Not rectifying ABA accessibility issues could result in claims filed against the Base for lacking accommodations.

Not replacing the noted electrical and mechanical systems will result in higher operational and ongoing maintenance costs. Leaving the existing boiler plants as is without redundancy creates the risk of losing heat in half the building if one component in the plant fails. Ongoing maintenance of fluorescent lighting fixtures will result in ongoing costs for bulb/ballast replacements. Ruptured fluorescent bulbs present a potential health and safety hazard.

2.5 Cost Estimate

The following cost estimate analysis is based on UFC 3-730-01 Programming Cost Estimates for

Military Construction and UFC 3-701-01 Data Tables updated February 2021.

Square Foot Costs

Facility Unit Cost – Aircraft Operations w/o Tower, 47,000 SF $306.00

Size Adjustment Factor “S” – 9,750/47,000 = .21 1.20

Location “ACF” – Grand Forks AFB, ND 1.05

Cost Escalation “CE” – Mid-point of Construction 2024 1.0612

Technological Updating Adjustment “TU” 1.00

Design Contingency Adjustment “DC” 1.05

Adjusted Guidance Cost Unit (per SF) $430.00

Alteration Project Estimates (using DA Form 7307-R)

Minor Renovation - $430.00 x .3636 x 9,740 SF = $1,523,000

Moderate Renovation - $430 x .5939 x 9,740 SF = $2,487,000

Major Renovation - $430 x .8409 x 9,750 SF = $3,525,000

See Appendix E for DA Forms 7307-R Cost Estimating Worksheet – Facility Alteration associated with each option.

Site Accessibility Concerns B528 is located on the west edge of the Base campus, at the east edge of the airfield. Access is convenient through Base traffic roadways. B528 serves as a structural element of airfield security, and temporary measures will be required during construction to maintain airfield security while providing access to the building for construction.

Construction Security Temporary airfield security fencing will be required to bypass B528 while maintaining airfield security and allowing unrestricted access to the building for construction.

Temporary user space Complete vacation of B528 is recommended during repairs/renovation.

Assumed that OSS will identify space in existing facilities for temporary relocation of Airfield Management and Weather Element. In addition to standard communication systems, Weather Element will require temporary relocation and/or connection to airfield weather monitoring equipment.

Facility Addition No additions to the facility are anticipated as part of this repair/renovation.

PART 1 - OVERVIEW

1.1 OVERVIEW

1.1 –OVERVIEW

Background:

Personnel for the 319th Operations Support Squadron (OSS) are currently located in multiple facilities.

Leadership has directed that OSS functions be relocated and consolidated to allow more direct and efficient management. Three buildings are under consideration:

• Building 528 houses several OSS functions. Originally built in 1958, the last significant renovation/addition was in 2000, and all major building systems need significant repair or replacement.

• Building 631 is currently unoccupied and is identified as a potential location to consolidate OSS functions. Construction of Building 631 was completed in 1998 and the building has had no significant work since.

• Building 607 currently houses several OSS functions. Building 607 was originally built in 1960 with several renovations and additions over the years. The last major remodel occurred in 2006.

OSS functions may be added or removed from Building 607, but no significant renovation/repair is intended in this building. Area A in green below is the current OSS area, and Area B in red below is being considered for OSS expansion.

Space Planning Study:

Part 5 of this report includes the Space Planning Study with options for relocating OSS into these three buildings.

Facility Assessment:

Prior to creating the Space Planning Study, a facility assessment was performed for the entirety of

Buildings 528 & 631. Since work is limited to the interior of Building 607, site and exterior envelope assessment was not performed on this building.

Boiler plant consists of two (2) Gas Fired Fulton Pulse Combustion Boilers, 500 MBH each, with an inline pipe mounted circulation pumps for each boiler. Multiple inline pumps used to serve different piping loops in the building.

Building is split in half with one boiler serving the north half and one boiler serving the south half.

There is no redundancy built into the system so if one boiler or pump fails there is no heat for the area of the building that it serves.

Exterior rooms have fin tube radiation, vestibules and mech/elec spaces have hot water unit heaters, and hot water reheats are installed in VAVs in ductwork to provide primary zone level heating.

The boilers are in good condition but approaching the end of their service life. It was also reported that the boilers are undersized and cannot maintain heating setpoints. A central boiler plant with redundancy should be installed to heat the entire building. Some pumps have been replaced over the years as they have failed. During a boiler system upgrade, associated pumps should also be upgraded. Fin tube radiation and cabinet/suspended unit heaters are in good condition. Heating coils are integral to air side equipment and should be replaced at time of air handler or terminal replacement. The newer air handling unit does not have a heating coil and the mixed air temperature gets bellow design temperature during extreme low outside air temperatures.
