INTRODUCTION

2.1 Scope of Civil Work

The West Cargo site will be developed in two phases. The proposed Phase 1 civil work will extend the existing aircraft parking apron north, construct concrete pavement storage areas for GSE and air cargo containers, construct parking for employees and overflow semi-trailers, and support construction of a new 112,350 square foot Air Cargo building.

The proposed Phase 2 civil work will construct concrete pavement storage areas for GSE and air cargo containers, construct parking for employees and overflow semi-trailers, and support construction of a new 53,400 square foot Air Cargo building.

The study explored several aircraft parking configurations to ensure compliance with FAA Part 77 surfaces, maintain adequate wingtip to wingtip spacing, ensure adequate space for pushing aircraft out of their parking spaces, and consider impacts of jet exhaust velocities at break away taxi power. The aircraft initially considered for Phase 1 of the project were the Boeing 737-8W and Airbus A330-300 based on the aircraft fleet of the assumed primary tenant. With no addition to the parking apron and current aircraft parking on the south end of the apron, four to six aircraft parking spots are possible on the north side of the apron depending on the mix of aircraft.

The study developed the initial Phase 1 building and apron layout with the assumption that Phase 2 of the project would include a new building and construction of additional aircraft parking apron. The study eliminated the aircraft apron from Phase 2 due to:

1. FAA Part 77 surface constraints and site constraints limiting the aircraft size to B737 and B767. Aircraft movement was not practical and there were concerns with B767 exhaust velocities. Input from the MAC was that it was not economically practical to construct additional apron space for only B737s due to air cargo carriers utilizing larger aircraft and B767s phase-out of cargo use.

2. Constructing an aircraft apron would require siting of the Phase 2 building that would result in inefficient tractor-trailer circulation.

Elimination of the aircraft apron allowed the Phase 2 building to be positioned to allow greater flexibility in siting the Phase 1 building. Phase 1 will include an addition of approximately 175’ of apron pavement to the north end of the West Cargo apron to maximize future versatility of the site and maximize GSE and cargo container/cargo handling and storage.

Reconfiguration of the Phase 1 and Phase 2 sites allowed for improved tractor-trailer circulation and centralized employee parking.

The building locations will be located outside the airport Building Restriction Line and building heights will not penetrate Part 77 surfaces.

The site is undeveloped and will require site preparation to excavate and place new base and subbase material to support the new concrete and asphalt pavement. The site is currently used as a contractor storage and staging area.

There are approximately 25,000 cubic yards of concrete/asphalt/soil debris material in mounds that will need to be removed from the site during both phases of the work. This estimate is approximate as of August 2025. Volumes would need to be validated at time of bidding.

Opportunities to incorporate sustainable site elements could include bicycle storage, accommodation for low-emitting and fuel-efficient vehicles, and designating a portion of employee parking for car-share vehicles.

2.2 Scope of Civil Work

Work will include construction of 18-inch concrete pavement for aircraft parking, 12-inch concrete pavement for air cargo buildings apron, GSE and air cargo container storage, asphalt pavement for tenant and customer parking, overflow semi-trailer parking and general circulation.

Work will also include utilities, parking apron and employee/trailer parking lighting, communications, security fencing, and pavement marking. Utilities and communications are available on and adjacent to the site.

2.3 Phase 1 Development will include the following:

1. 17,000 square yards of 18-inch concrete pavement/base/subbase.

Parking apron work will include new lighting and pavement marking.

2.	9,700 square yards of 12-inch concrete pavement/base/subbase.
3.	31,400 square yards of asphalt pavement/base/subbase. The

pavement will support Phase 1 traffic and future Phase 2 traffic/ parking.

i. Existing entry to the site from Longfellow Ave. will be widened approximately 20ft to accommodate tractor-trailer entry and exit due to constrained turning radius.

ii. New acceleration lane will be constructed on Longfellow Ave to accommodate tractor-trailer traffic exiting to the north to mitigate limited sight line to vehicle traffic approaching from the south.

4. Underground utilities to support the Phase 1 Air Cargo building and site. Recommend relocating existing eighteen-inch water and six-inch natural gas utilities to avoid disrupting the Phase 1 site during Phase 2 construction. The proposed first phase requires a formal stormwater management review as it exceeds the one (1) acre new impervious surface threshold set by the MAC for new development.

To manage the resulting increased runoff volume and discharge rates, the project is required to include on-site detention to attenuate the peak flows before discharging into the far upstream end of the storm sewer network that feeds MSP Pond No. 1. This is necessary to comply with the Rate Control criteria, which mandates that the proposed activity shall not lead to an increase in existing runoff rates as measured at the discharge point to the Minnesota River.

5. Jet Blast Deflector – There is a concrete retaining wall with varying height (8’-10’) on the west side of the West Cargo apron adjacent to Longfellow Avenue. Current aircraft operations are primarily B737 and B767; exhaust velocities do not appear to have an impact on vehicle movement. If future use is expanded to include larger aircraft, recommend installing a jet blast deflector to mitigate higher exhaust velocity issues. Basis of design: Jet Blast Deflectors Inc, G20NB-4, will accommodate A330, 777F, up to 747-400F.

6. Tie new AOA fencing from Phase 1 building to existing AOA fencing.

2.4 Phase 2 Development will include the following:

1.	8,500 square yards of 12-inch concrete pavement/base/subbase.
2.	18,600 square yards of asphalt pavement/base/subbase.
3.	Underground utilities to support the Phase 2 Air Cargo building

and site.

4.	Snowmelter – basis of design: Trecan 120-SG
5.	550 linear feet of AOA fencing and superposts to secure airside

operations.

4.1 INTRODUCTION

1. Purpose

a. The purpose of this report is to describe the proposed building systems for planning, design, coordination, preliminary pricing, and Owner review.

b. The proposed design assumptions are outlined for Owner review and approval. These assumptions include, but are not limited to, external and internal temperature and humidity criteria, noise limits, occupancy, vibration criteria, future expansion needs, fire resistance, and lighting levels

c. Proposed building systems may evolve during the design phases. Any preliminary pricing must include cost contingencies appropriate to the current phase.

d. Refer to Architectural Design conceptual drawings, project program, and Owner’s design and construction standards for additional information.

2. Project Description

a. The project consists of the construction of two buildings to be utilized for air cargo transportation services that will be constructed in two phases. The first phase is for an approximately 126,000 SF building to house 3 tenants, each with warehouse and office suite spaces, a TSA space, and a MAC core area.

The second phase is for an approximately 52,200 SF building to house an undetermined number of tenants. Both buildings will be of insulated precast concrete panel construction with precast concrete spans covered by single-ply PVC insulation over rigid insulation. Store front glazing will be utilized at the vestibule entry, and the warehouse spaces will have large overhead doors on both sides for inbound and out bound cargo. This report covers Phase 1 proposed mechanical systems.

3. Sustainability and Energy Goals

a. The pursuance of a LEED Silver accreditation is being considered by the owner.

b. Solar Wall panels are to be utilized for the preheating of outdoor ventilation air to the air handling equipment. Refer to the HVAC Systems portion of this report for additional information.

c. A geothermal heating/cooling system was reviewed as a possible energy efficiency strategy. However, after reviewing HVAC systems scope against building space use it was determined that would not be a good application for this project. Refer to the HVAC Systems portion of this report for additional information.

4.4 PROPOSED MECHANICAL SYSTEMS

1. General HVAC System Description

a. Tenant warehouse spaces will be provided with ventilation by rooftop air handling equipment with natural gas fired heat, energy recovery wheels, and MERV 11 air filtration. No space cooling will be provided. Hydronic unit heaters will supplement space heat in addition to addressing infiltration from overhead doors.

Relief air will be provided by the energy recovery component of the air handling unit. A Solar Wall system will be utilized for pre-heating of outdoor air during the heating season and outdoor air ductwork will be extended from the Solar Wall duct collars to the outdoor air intakes at the rooftop air handling units. Large prop fans will be provided for air temperature destratification.

b. Tenant suite spaces and the TSA space will be provided with HVAC by rooftop air handling units with outdoor air ventilation, hydronic heating coils, DX cooling, and MERV 11 air filters.

Ductwork will be extended from the air handling units to variable air volume (VAV) boxes with hydronic heating coils and then to supply air diffusers. Exhaust air fans will service toilet room and janitor closets. Electric cabinet unit heaters will be provided in entry vestibules.

c. The MAC Core space will be served by a rooftop air-handing unit with outdoor air ventilation, hydronic heat and MERV 11 air filtration, but no cooling.

d. The MAC Core space will also contain the building hydronic heating boilers, pumps, and hydronic specialties. The energy used by the tenants will be tracked by dedicated energy (BTU) meters installed on the hydronic lines that extend to the tenant spaces. A building control and energy management system will be provided in accordance with MAC Standards and integrated into the MAC IMACS control system.

e. Solar Wall panels are proposed for installation on this building.

The panels are a propriety product that consists of a custom metal panel assembly with an interior void space and perforations on the exposed front surface that allow for outdoor ventilation air to be drawn in to the panel where it is pre-heated prior to discharging into the outdoor air intake section of air handling units. A means of bypassing the panels is provided for outdoor air provisions outside of the heating season. The panels are marketed as providing for a significant reduction in heating energy use during periods of daytime solar light radiation accessibility in the winter season.

f. The possibility of integrating a geothermal system component into the building HVAC systems was investigated as part of this report study. However, due to the imbalance between the high heating demand and the low cooling demand of the building it was determined that this building was not a good candidate for a geothermal application. This extends behind the concern of the potential for the well field to become irreparably imbalanced, which could be addressed by a Darcy type geothermal well, to include concerns of heat pumps sized for the heating load that will have a cooling fluid flow too low for the resultant compressors.

Utilizing several smaller heat pumps was found to not be either cost or space efficient. Also, due to the increasing demand for Darcy geothermal systems the lead times and costs of the systems have risen dramatically.
