STATEMENT OF WORK (SOW)

PROJECT NUMBER: PJMS252006

MARYLAND AIR NATIONAL GUARD

MARTIN STATE AIRPORT

NATIONAL GUARD BASE

MIDDLE RIVER, MARYLAND 21220

31 July 2025

1. General Project Information:

1.1. Project Location and Background: This project is located at the Hwy 43 Entry Control Point (ECP) on the Maryland Air National Guard Base (MDANG), Martin State Airport, Middle River, MD 21220. Approximately one year ago, a high-speed vehicle crash rendered the inbound swing gate and several adjacent in-ground bollards inoperable. The current system no longer meets Unified Facilities Criteria (UFC), Antiterrorism (AT)/Force Protection (FP), and operational requirements.

1.2. The ECP consists of two existing manual double swing gates—controlling inbound and outbound vehicular traffic—on either side of Guard House Bldg 2000. The inbound swing gate and adjacent bollards require full replacement.

1.3. Site Description: This facility always requires security protection. Absolutely no photography of aircraft is permitted.

1.4. Use of Premises:

· The contractor shall assume full responsibility for protection and security of materials and equipment stored on site.

· Replace six in-ground anti-vehicle bollards;

· Replace approximately 9 linear feet of damaged perimeter fencing;

· Provide bonding and grounding for new gate installations;

· Restore any disturbed landscaping or hardscape features;

· Trim trees if required to complete the scope of work (with COR coordination and approval);

· Ensure continuity of perimeter security throughout construction;

· Coordinate traffic and environmental considerations.

3. Required Base Scope

3.1. Demolition and Replacement:

· Remove and replace both inbound and outbound swing gates with new equivalent manual swing gates, matching existing dimensions, frame construction, and materials (e.g., galvanized steel), but upgraded to meet all current UFC 4-022-03 height requirements, including the addition of three-strand barbed wire outriggers angled at 45 degrees.

· The bottom of the gate shall maintain a maximum clearance of no more than 4 inches from the finished road surface at all points along its length. Gaps between the gate frame and adjacent gate posts or supporting structures shall also not exceed 4 inches in any direction.

· Provide shop drawings of proposed gate assemblies, including detailed structural and component specifications.

· Remove and replace six damaged in-ground anti-vehicle bollards. Bollards shall meet ASTM F2656 M30/P1 rating minimum (which means they can stop a 15,000 lb.

vehicle traveling at 30 mph in less than 1 meter penetration). Bollards shall be embedded in reinforced concrete foundations to a minimum depth of 36 inches and include integrated lockable receptacle caps if removable.

· Remove and replace approximately 9 linear feet of decorative anti-personnel fencing to match adjacent fencing aesthetics and structural design.

3.2. Grounding and Bonding:

· Electrically bond all metallic components of each gate using #6 AWG copper jumpers.

· Ground each gate using a 5/8" x 10' copper-clad ground rod embedded a minimum of 8 feet below grade.

· Grounding system shall be tested using a clamp-on ground resistance tester.

Resistance must not exceed 25 Ohms. If resistance exceeds 25 Ohms, install additional rods spaced at least 6 feet apart.

· Submit test results detailing test method, ambient conditions, and measured resistance for each gate.

3.3. Site Restoration and Landscaping:

· Restore all disturbed landscaped areas using a topsoil depth of no less than 4 inches, followed by reseeding with MDOT SHA-approved turfgrass mix.

· Restore any disturbed asphalt using 4" thick hot-mix asphalt (HMA), MDOT SHA P- 403 or equivalent.

· Restore disturbed concrete using 6" thick 4000 psi air-entrained concrete with broom finish to match existing.

3.4. Tree Trimming:

· The contractor shall maintain a minimum vertical clearance of 12 feet and horizontal clearance of 3 feet from gate travel paths.

· Submit request for trimming with justification and pre-work photos. Written approval from COR is required prior to trimming.

3.5. Perimeter Security:

· The contractor must install a continuous temporary security fence that connects to the permanent fencing at both ends of the project site. The fence must maintain full perimeter integrity using chain-link fencing at least 7 feet high, anchored or ballasted, and equipped with anti-lift attachments. The contractor is responsible for securing both the gate and the perimeter throughout construction.

· Since this gate serves as the installation’s backup exit, the contractor must also be able to make at least one lane accessible for vehicles within four hours of government notification. This temporary access will stay in place until the Main Gate is back to normal operation.

· If a temporary breach in perimeter security is required, notify the COR in writing at least 24 hours in advance, including location, duration, and proposed mitigation.

3.6. Traffic and Environmental Coordination:

· Submit traffic control plan detailing signage, barricades, flagging operations, and staging zones. The plan must be approved by COR and KO.

· Coordinate internal traffic impacts with 175th Security Forces Squadron and external coordination with Baltimore County Police as required.

· Conduct hazardous paint testing prior to demolition. If lead-based paint is found, halt work and notify COR and KO immediately.
