2.0 Project Description

2.1. General The project consists of a new explosive cargo load unload apron, a new parking apron, two new ladder taxiways, and a reconstructed and extended parallel taxiway on Mihail Kogălniceanu Air Base (MKAB) near Constanta, Romania. Design and construction efforts must be executed in accordance with the Host Nation agreements for European Deterrence Initiatives (EDI) to include construction and environmental permits. The existing taxiway oriented parallel to the existing runway is known as parallel Taxiway F. The existing taxiway with temporary arm/disarm pad connecting Taxiway F to the existing runway is known as Taxiway E. The new taxiway located parallel to and south of Taxiway E connecting to Taxiway F must be known as Taxiway G. The new ladder taxiway connecting the existing runway to the new explosive cargo load unload apron and Taxiway F must be known as Taxiway H. A conceptual design accompanies this Statement of Work (SOW) as Appendix A of this document. The conceptual drawings provided in Appendix A of this RFP are notional only. The D-B Contractor must develop and complete the entire design. The D-B Contractor must be the Designer of Record (DOR).The project must be designed in accordance with the design criteria outlined in this Statement of Work and the conceptual drawings provided in Appendix A. As the DOR, the D-B Contractor must collect data and revise the conceptual design as needed to provide a fully functional layout in compliance with all applicable regulations and design standards and in consideration of all valid constraints and impacts. In addition, since this project includes a fire protection system, a Qualified Fire Protection Engineer (QFPE) must be included as part of the D-B Contractor’s design team. The D-B Contractor must be responsible for the professional quality, technical accuracy, and the coordination of all designs, drawings, specifications, and other non‐construction services furnished by the D-B Contractor. The D-B Contractor must, without additional compensation, correct or revise any errors or deficiency in its designs, drawings, specifications, and other non‐

2

construction services and perform any necessary rework or modifications, including any damage to real or personal property, resulting from the design error or omission. The D-B Contractor’s point of contact throughout the project must be the USACE Contracting Officer’s Representative (COR).

2.2. Project Site The site for this facility is in the northwest corner of the airfield section of MKAB and is located immediately adjacent to Mihail Kogălniceanu International Airport as shared by the U.S. Army and Romanian Ministry of Defense (MOD). The combined facility is located approximately 25 km northwest of the city of Constanta. MKAB is positioned at 44°21’43.43” N longitude and 28°28’14.79” E latitude and has an elevation of 108 meters (353 feet) above sea level. The runway is owned and operated by the Romanian Government civilian air authority and the taxiways located west of the runway are owned and operated by the Romanian MOD in conjunction with the Romanian Government civilian air authority. The area where the facilities will be constructed covers approximately 19.2 hectares (47.5 acres). Most of this area was previously developed to serve previous iterations of MKAB operated by the Romanian military. Several earthen berms, concrete bunkers, buildings, concrete and gravel roads and platforms, and debris piles cover much of the site. At the time this RFP was prepared, the site is bounded by the MKAB perimeter fence to the north, the airport runway to the east, existing buildings and airfield infrastructure to the south, and railroad tracks to the west. Multiple future projects are adjacent to this project and are anticipated to be in design and/or under construction at the time this RFP is issued. A Railhead Facility will be located to the west, a Fuel Storage Facility will be located southwest, a C-17 parking apron will be located south, and a U.S. Army Ready Building will be located southwest of the parking apron portion of this project. These adjacent projects are collectively referred to as MK-1 and are anticipated to provide opportunities for the D-B Contractor to make utility connections. In addition, a future 2 MW power station will be located west of the future MK-1 Railhead Facility. This RFP assumes these projects will provide utility connections, which are included as Base Bid items. The D-B Contractor must coordinate and work with any contractors in the area.

2.3. Explosive Cargo Load Unload Apron The explosive cargo load unload apron must accommodate a single C-17 aircraft and will allow the aircraft to taxi in and taxi out under its own power. Aircraft will access the apron from proposed ladder Taxiway H. Aircraft will taxi out from this apron eastward along Taxiway H to parallel Taxiway F, turn south onto Taxiway F and turn onto the proposed parking apron or head further south to Taxiway G.

The center of the curved portion of the explosive cargo load unload apron must be an adequate distance away from the edge of the runway to ensure take-off and landing is not impacted by the presence of explosive cargo on this apron. Mooring points will be provided to accommodate a single C-17, a single UH-60, and single CH-47 rotary wing aircraft using the apron at different times.

The explosive cargo load unload apron must be constructed of Portland Cement Concrete (PCC) pavement with a drainage layer. Paved and unpaved shoulders must be provided along the access taxiway and around the perimeter of the pad to protect adjacent areas from jet blast, help mitigate foreign object damage (FOD), permit equipment storage, and to facilitate drainage. Paved shoulders must be constructed of Hot Mix Asphalt (HMA) pavement. An Oil Water

3

Separator (OWS) must be provided to minimize adverse environmental impacts in case of an inadvertent spill of petroleum, oil, or lubricants (POL) or other liquids from the aircraft.

2.4. Parking Apron

The parking apron must accommodate three (3) C-17 aircraft simultaneously and allow aircraft to taxi in and taxi out under their own power. Aircraft will access the parking apron from parallel Taxiway F. Aircraft will taxi out to parallel Taxiway F heading south and turn onto Taxiway G to gain access to the runway. The section of existing Taxiways E and F intersected by Taxiway G will be reconstructed to support loads imparted by C-17 aircraft.

The parking apron must be constructed of Portland Cement Concrete (PCC) pavement with a drainage layer. Paved and unpaved shoulders must be provided along the access taxiway and around the perimeter of the pad to protect adjacent areas from jet blast, help mitigate foreign object damage (FOD), permit equipment storage, and to facilitate drainage. Paved shoulders must be constructed of Hot Mix Asphalt (HMA) pavement. An Oil Water Separator (OWS) must be provided to minimize adverse environmental impacts in case of an inadvertent spill of petroleum, oil, or lubricants (POL) other liquids from the aircraft.

Tie-downs in the parking apron must be provided to allow simultaneous mooring of three (3) C-17 aircraft and simultaneous mooring of three (3) CH-47 rotary wing aircraft and the maximum number of UH-60 aircraft as feasible. Location of moorings must assume fixed wing and rotary wing aircraft will be occupying the parking apron at different times.

2.5. Demolition and Debris Removal Earthen berms, bunkers, buildings, and debris piles that lie within the project footprint and within required clear zones must be removed and hauled off site in compliance with Romanian Government rules and regulations as part of the scope of work for this project. Note that demolition must not commence prior to issuance of an Urbanism Certificate and Demolition Permit by the Romanian Government (See Section 3.0 Permits and Approvals).

3.0 Permits and Approvals It is the D-B Contractor’s responsibility to verify all permitting procedures and requirements and obtain required permits and approvals prior to starting construction. Basic Information regarding Romanian Government approvals and permits follows. 3.1. Urbanism Certificate

4.2. Explosive Cargo Apron, Parking Apron, and Taxiway Design Design Life

The airfield pavement systems must be designed to a minimum life of 20 years in accordance with UFC 3-260-02, Chapter 2.

Layout and Geometry

4.2.2.1. Horizontal Geometry The D-B Contractor must design and construct an access taxiway (Taxiway H) and a semicircular explosive load unload apron that accommodates parking for one C-17 aircraft. Locate the pad so that no part of the pad or the parked aircraft penetrates the approach/departure surfaces or the 7:1 transitional surface. The facility must be designed for aircraft to taxi in and out under their own power. Tie-down/mooring points/eyes are required for one C-17, one UH-60, and one CH-47 aircraft. Grounding points are required per the requirements of UFC 3-260-01, Appendix B, Section 11, Static Grounding Tie-down. Additionally, the D-B Contractor must construct a new access taxiway and new aircraft parking apron, located south of the explosive cargo apron. The new access taxiway (Taxiway G) will be constructed parallel to and south of Taxiway E. The runway to taxiway centerline curves must be constructed to a single 45.72 m (150 ft) radius to meet UFC 3-260-01 taxiway centerline criteria. The taxiway to taxiway centerline radii curves must be constructed to a 38.1 m (125 ft) radius to meet UFC 3-260-01 criteria. A minimum 45.72 m (150 ft) clearance from taxiway centerline to fixed or mobile obstacles must be provided. A minimum 38.1 m (125 ft) clearance from apron boundary markings to fixed or mobile objects must be provided. A taxiway connection between Taxiway H and Taxiway F must be provided. Due to the limited area allowable, the edge radius on the west side of this intersection is 25m (82 ft) to hold the north-south project limits. The pavement must be configured to maintain the required 38.1m (125 ft) centerline radius at this intersection. All taxiways and taxilanes must have a width of 22.5 m (74 ft) per NATO geometric design criteria. The new facility must be located so that no part of the aprons or parked aircraft penetrates the approach/departure surfaces or the 7:1 transitional surface. Explosives site planning is required and the facility must be sited in accordance with DoD Standard 6055.9. Separation from electromagnetic radiation is required to prevent ignition of electro-explosive devices (EED). The primary explosives site development criteria are defined as follows:

8

• 13,608 kg (30,000 lb.) Class HD 1.1 • Quantity Distance (QD) arc of 380 m (1,250 ft) radius per Department of the Army Pamphlet 385-64: Ammunition and Explosives Safety Standards, dated 24 May 2011 (DA PAM 385-64).

• Inhabited Building Distance (IBD) arc of 380 m (1,250 ft) radius per Table 8-7 of DA PAM 385-64.

4.2.2.2. Vertical Geometry

Longitudinal slopes for the new taxiways must be governed by the existing pavement to remain. Longitudinal slopes of Taxiway G must be governed by the existing pavement to remain on Taxiway E and the tie point on the runway. All longitudinal slopes and profiles must be developed to maximize the existing grade conditions and provide for smooth transitions for taxiing aircraft. The longitudinal grade of taxiways and shoulders must not exceed 3.0% and taxiway transverse grades must be between 1% and 1.5% per UFC 3-260-01. The transverse grade of paved and unpaved parking apron shoulders must be between 2% and 4%. Parking apron surface grades must be a maximum of 1% in accordance with Romanian criteria.

Geometric Conflicts The conceptual layout provided in this RFP is the result of mixing Army, UFC and NATO criteria to avoid conflicts with surrounding features with respect to QD/IBD circles and clear distances and to keep the project within the Primary Facilities quantity limits defined in the DD 1391 programming document. The D-B Contractor must anticipate utilizing both NATO and UFC criteria in their design to keep within established physical and programming limits. Preliminary design of the future adjacent railhead project shows that this project will require design coordination with the future railhead facility. At the 95% design submittal stage, the future railhead project extended approximately one meter into the parking apron taxilane clear zone. A section of jet blast fence is provided on the conceptual drawings to protect the future railhead facility from jet blast. Refer to Section 4.3 for more information.

Tie-Down and Grounding Requirements The parking apron must accommodate long-term parking for two C-17 aircraft and short-term parking for one C-17 located on the peripheral taxilane. Tie-down/mooring points/eyes are required on the parking apron for three (3) C-17, three (3) CH-47, and the maximum number of UH-60 aircraft as feasible. Grounding points are required per the requirements of UFC 3-260-01, Appendix B, Section 11 - Static Grounding Tie-down. On the explosive cargo apron, the D-B Contractor must provide tie-downs/moorings for a single C-17, a single UH-60, and single CH-47 rotary wing aircraft using the apron at different times. Grounding points are required per the requirements of UFC 3-260-01, Appendix B, Section 11 - Static Grounding Tie-down.

Airfield Pavements The design of the airfield pavement must be in accordance with UFC 3-260-01 Airfield and Heliport Planning and Design and UFC 3-260-02 Pavement Design for Airfields using the US Air Force requirements. This project is in a region where frost design is required; therefore, the base courses must utilize non-frost susceptible materials and a subdrain system must be provided. The taxiways and aprons must be surfaced with Portland Cement Concrete (PCC). The pavement sections developed in the following paragraphs are to be considered minimum requirement sections. The Design Build Contractor’s designer is the designer of record. As such, the D-B Contractor is responsible for the ultimate design and thickness of the pavement layers for this project. PCASE software may be utilized, per UFC 3-260-02. This software is available for download at http://www.pcase.com. In no case, unless authorized by USACE, must the constructed airfield pavement section be less than what is specified in this RFP. UFGS Specification Section 01 33 16.00 and Section 7.0 of this RFP provides geotechnical investigation and reporting requirements to be used in pavement design. The D-B Contractor's geometric layout and pavement design of any new, temporary or altered aircraft circulation and parking area must generally consider the types of vehicles expected to use the areas, the proposed amount of traffic, the design speed and any other types of stress applied to the surfaces.

4.2.5.1. Geotechnical Information A geotechnical investigation was conducted in July 2018 and the data from that investigation can be found in Appendix E.

4.2.5.2. Subgrade Properties The geotechnical investigation revealed that the subgrade soils are variable in texture and cross-section profile, with soils primarily consisting of a Clayey Silt (CL) soil. The CBR values varied from 4.99 to 6.64, determined using a modified proctor. A maximum CBR value of 5 must be utilized for flexible pavement sections (shoulders) on existing soil. For rigid pavement design, a maximum Modulus of Subgrade Reaction (k) value of 21 kPa/mm (77 pci) must be utilized for existing soil, per the geotechnical investigation results. Based on the geotechnical data, a frost classification of F3/F4 must be utilized in the design, based on PCASE and UFC 3-260-02 Pavement Design for Airfields.

4.2.5.3. Concrete Strength The design flexural strength of the concrete must be at least 4.48 MPa (650 psi) at 90 days. No reduction in thickness must be allowed for design strengths above 4.48 MPa (650 psi).

4.2.5.4. Design Traffic The selected design traffic for this apron is US Air Force medium load traffic without the B-52 or F-15E aircraft. The U.S. Air Force traffic pattern was prescribed during the May 2018 Design Charrette because the facility design is based on C-17 aircraft, a U.S. Air Force Strategic Transport Aircraft. Specifically, the traffic must be:

C-17 100,000 passes at 265,352 kg (585,000 pounds)

10

For the explosive cargo load unload apron and the parking apron, UFC

3-260-02 assigns a Type B Traffic Area designation.

For the access taxiways, UFC 3-260-02 assigns a Type A traffic area designation.

Shoulder design must be based on the PCASE standard parameters.

The number of passes was prescribed by the USACE project programming documents. Over the 20-year design life, this translates into approximately 13 aircraft passes per day.

4.2.5.5. Thickness Design

The thickness design for the minimum pavement section was calculated using the Pavement-Transportation Computer Assisted Structural Engineering (PCASE) software version 2.09.05. The frost depth in the project vicinity is 85 cm (33.5 inches) per Romanian Standard STAS 6054-77. Printouts of the PCASE runs are shown in Figure 3-1 and Figure 3-2, below. The thickness for the explosive cargo load unload and parking aprons for Type A traffic area is 354 mm (13.93 inches) unreinforced PCC, on 113 mm (4.44 inches) drainage layer, on 390 mm (15.35 inches) of aggregate base course layer on compacted subgrade.

Figure 3-1: PCASE Output – PCC Taxiways and Aprons

11

Figure 3-2: PCASE Output – HMA Shoulders The PCASE design for the Type A traffic area resulted in a PCC section that is approximately 8 mm (0.31 inch) thicker than the Type B traffic area. Therefore, the thicker taxiway requirement (Type A traffic) must be extended to the entire footprint of the project as the minimum design. See Figure 3-1. Figure 3-2 shows the PCASE data for the shoulder area. The thickness for the shoulder pavement, as seen in Figure 3-2 and given by PCASE, is 102 mm (4 inches) hot-mix asphalt (HMA), on 152 mm (5.98 inches) of aggregate base course on 102 mm (4.02 inches) drainage layer on geotextile fabric on compacted subgrade. However, since the site can be subjected to approximately 85 cm (33.5 inches) of frost (per Romanian Standard STAS 6054-77), the shoulder pavement thickness design must be modified as follows to prevent frost heave of the HMA pavement: The surface must be 102 mm (4 inches) HMA, on 252 mm (9.92 inches) of aggregate base course equal to the thickness of PCC access apron. The thickness of the drainage layer both for the PCC and HMA must be 113 mm (4.45 inches), the depth of the geotextile layer must match the top of the base course under the PCC apron, and an additional 383 mm (15.08 inches) layer of aggregate bring the section below the depth of frost penetration and match the PCC pavement section depth. The substantial subgrade uniformity under the two paving features will prevent heaving of the shoulder pavement. Minimum pavement sections for this facility must be as follows:

4.2.5.6. Aggregate Drainage Layer

The D-B Contractor must develop UFGS specifications for drainage layers with rapid draining material and/or an open graded material stabilized with cement or bituminous material. Materials properties must follow UFC 3-260-02 Pavement Design for Airfields and UFC 3-230-06A subsurface drainage.

4.2.5.7. Subdrain Design A subdrain system must be included as part of the design to collect infiltrated surface water. This infiltrated surface water is likely to enter the pavement from the surface through cracks or joints in the pavement, through pores in the pavement, and through shoulders and adjacent areas. The system must consist of a minimum of 150 mm (6 inch) diameter Perforated Polyvinyl Chloride (PPVC) pipe, flushing and observation risers (cleanouts) at required spacing, manholes, discharge laterals, filter fabric, and trench backfill. The subdrain system must be located below frost line to the extent practicable. The system must be designed to maintain positive flow, and in accordance with UFC 3-230-06A Subsurface Drainage.

4.2.5.8. Unpaved Shoulders Per Section 5-11.1.2 of UFC 3-260-01, unpaved shoulder areas must be designed based on the maximum number of wheels and the maximum gross weight of the design aircraft on the unpaved shoulder. In no case, must the design be less than computed stress conditions created by a wheel load of 22,667 kg (50,000 lb) at a contact pressure of 1,724 kPa (250 psi).

4.2.5.9. Paved Jet Blast Protection Area In accordance with Appendix B8-1.3 and Appendix B7-3 of UFC 3-260-01 and ETL 07-3: Jet Engine Thrust Standoff Requirements for Airfield Asphalt Edge Pavements referenced therein, the area along the west edge of the parking apron between the edge of paved shoulder and the jet blast deflection berm must be paved with a minimum 51 mm (2 inches) thick layer of asphalt. This paved jet blast protection area must be designed to match the strength requirements of the unpaved shoulders.

13

4.2.5.10. Rigid Joint Pavement All airfield pavement joints must be designed in accordance with UFC 3-260-02 Pavement Design for Airfields.

Pavement Markings Aircraft surface movement and parking aprons must be marked in accordance with UFC 3-260-04 Airfield and Heliport Marking. Included are centerline stripes, nose wheel guidelines, edge markings, and runway hold position markings. The centerlines of all taxiways, taxilanes on aprons, as well as parking positions and pads will be marked with a single continuous 152-millimeter (6-inch)-wide retro-reflective yellow stripe with glass beads, highlighted by marking a black, non-reflectorized 152-millimeter (6-inch) border. In accordance with Section 7-2 of UFC 3-260-04, thermoplastic markings must not be used. All markings must be made with waterborne paint. The D-B must include this information in UFGS Specification 32 17 23 Pavement Markings based on this information.

4.3. Jet Blast Deflection Jet blast deflection must be provided on the west edge of the parking apron to protect the adjacent railhead project. Section 7 and Section 8 of UFC 3-260-01 Appendix B provide jet blast requirements and jet blast deflector criteria. A 10-meter (32.8 feet) wide (minimum) earthen berm is provided aft of C-17 parking areas shown on the conceptual drawings. The D-B must provide appropriate cover treatment to eliminate the effects of jet blast erosion. At the time this RFP was written, preliminary layout of the future railhead project showed a portion of the railhead loading area extending into the limits of the jet blast deflection berm by approximately one meter. Based on this potential conflict, a section of jet blast fence or similar barrier must be provided to protect the future railhead facility from the effect of jet blast aft of the parking apron while maintaining the aviation clear zone around the peripheral taxiway of the parking apron. The berm and blast fence are shown on the conceptual drawings in this RFP. Any jet blast fence or similar type of barrier will require drawings and supporting design calculations for all components including but not limited to the fence, connections, and foundation. The D-B Contractor must coordinate with the adjacent projects through the COR, as the constructed location of the future railhead facility may differ from the layout used in this RFP.

4.4. Access Roads Three access roads, A, B, and C, must be provided for this project. Roads A and B will connect the explosive cargo load/unload apron to the future MK-1 fuel storage facility and existing local access road, respectively. Road C is not part of the Base Bid for this project and is included as Optional Bid Item 5 to be designed and constructed only if project funds are available. Access roads must be designed in accordance with UFC 3-201-01 Civil Engineering, UFC 3-250-01 Pavement Design for Roads and Parking Areas, and UFC 3-260-01 Airfield and Heliport Planning and Design. All access roads must be conventional flexible pavement designed for a 25-year design life based on anticipated vehicles and loadings described in accordance with UFC 3-250-01 (note this design life differs from that required for airfield pavements). Per UFC 3-260-01 and NFPA-1, all access roads must have a minimum unobstructed width of 6.1 meters (20 feet) to accommodate fire and rescue vehicles. The minimum Design Vehicle is a P-23 Crash Truck (Fire Truck) with a gross weight of 350 kN (77,880 lb), per Figure E-22 of UFC 3-250-01.

14

Per Table 2-1 of UFC 3-201-01, the minimum longitudinal grade and minimum transverse grade of each access road must be 0.3% and 2.0%, respectively. Per Section 3-5 of UFC 3-250-01, design using PCASE is required for the design of all roads required in the project scope as well as additional aggregate to reduce frost penetration into the subgrade. The minimum thickness of the access road pavement section is 300 mm (12 inches), including surface course, aggregate base, and aggregate subbase. The minimum thickness of the surface course is 50 mm (2 inches). Provide a minimum thickness of 100 mm (4 inches) of aggregate base course and 150 mm (6 inches) of graded crushed aggregate for access road subbase.

4.5. Stormwater and Drainage

The D-B Contractor must design and construct any required drainage facilities to maintain existing drainage patterns and systems in accordance with Host Nation Government regulations, unless otherwise specified. Stormwater drainage such as overland sheet flow, open channels or piping must be designed in a manner that conveys stormwater away from any existing or planned structure and pavement and does not collect on or seep into the ground adjacent to or beneath any structure. Capture of storm water from exterior surfaces can be achieved by installation of inlets, gutters, swales or other adequate collecting systems. The D-B Contractor must design and construct infield grading and storm drainage features to prevent surface storage of water as required by the Host Nation to avoid Bird Air Strike Hazard (BASH) issues.

Background and Existing Conditions The existing runway is oriented north-south with existing gutters located at intervals along the edge of the concrete shoulder. Adjacent to the west of the gutters are stormwater manholes and stormwater pipes that convey runoff southward to the runway closed conveyance system’s discharge point, a canal located approximately 700 meters (0.43 miles) from the southern end of the runway that ultimately discharges to a tributary of the Black Sea. Hydrologic Criteria Hydrologic criteria must follow UFC 3-201-01 or local regulations, whichever is more stringent. Taxiways and aprons must use the minimum required by the local governing authority for airfields and heliports or a minimum 5-year storm frequency per UFC 3-201-01, whichever is more stringent. Intensity-Duration-Frequency data must be based on Romanian standards or sources, such as STAS 9470-1973. Spread Surface drainage systems must be designed in accordance with UFC 3-201-01. Per Section 3-1.2.1 of UFC 3-201-01, the maximum spread for airfields must not include runways, taxiways and heliport pavements or paved shoulders using a 5-year storm frequency. Per Section 3-1.3.1 of UFC 3-201-01, the maximum spread from airfield pavement must not encroach on the center 50 percent, along the centerline, of runways, taxiways, or apron surfaces using a 10-year storm frequency. Per Section 3-1.3.2 of UFC 3-201-01, the maximum spread for aprons is a depth of 100 mm (4 inches) using a 5-year storm frequency and the maximum ponding depth is 100 mm (4 inches) around apron inlets. Per Section 3-1.3 of UFC 3-201-01, the maximum spread for roads is ½ driving lane. The access roads must be considered local roads; therefore, a 5-year storm frequency must be used.

15

Drainage System Stormwater conveyance systems must be designed in accordance with UFC 3-201-01. Per Section 3-1.2.1 of UFC 3-201-01, the taxiways and aprons use the minimum required by the local governing authority for airfields or a minimum 5-year storm frequency. Per Section 3-1.2 of UFC 3-201-01, drainage systems serving the access roads must use a minimum 10-year storm frequency or the minimum required by the Romanian governing authority, whichever is more stringent.

A conceptual drainage design is shown on plan sheets CG101 through CG104. The D-B Contractor must design and specify all systems to meet or exceed UFC, Host Nation requirements and the most current editions of the International Building Code and International Plumbing Code. New drainage system infrastructure on the facility must be aircraft load rated. The D-B Contractor, as the DOR, must develop their own drainage system design, subject to approval by Romanian regulatory authorities, the civilian air authority and USACE during the design phase. The D-B Contractor must coordinate stormwater design and permitting through the COR. The conceptual drainage design assumes Polyethylene (PE) Pipe. Reinforced Concrete (RCP), Polypropylene (PP) Pipe, and Polyvinyl Chloride (PVC) Pipe are acceptable alternatives. Watertight joints must be provided. Corrugated metal drainage structures must not be used. Pipe connections to concrete manholes and inlets must be made with flexible, watertight connectors. Specification Section 33 40 00 Storm Drainage Systems must be developed by the D-B Contractor based on this information. To meet Romanian requirements related to hydrocarbon discharge as well as jet blast protection requirements, the shoulders on the downslope side of the aprons and ditches that receive runoff from the aprons must be asphalt-lined to prevent the seepage of pollutants into the soil. Refer to Section 4.2.3.10 Paved Jet Blast Protection Area of the RFP for additional information.

Runway Clear Zone Requirements Per Romanian Government requirements, an open ponded drainage system in the area between Taxiways E, F, G, and H adjacent to the runway is prohibited.

Oil/Water Separation Stormwater runoff generated by the parking apron and the explosive cargo apron must pass through an oil/water separator device prior to discharge. Oil/water separator devices must be designed or selected in accordance with Romanian Government regulatory requirements and standards, including HG 352/2005 and NTPA 001/2005.

Stormwater Low Impact Development (LID)/Volume Reduction Stormwater volume reduction goals must be compliant with Section 438 of the Energy Independence and Security Act (EISA) as required by UFC 3-210-10 Low Impact Development and/or by Romanian Government requirements, whichever are more stringent. The D-B Contractor must provide documentation of the project’s compliance with EISA Section 438 for all design submittals. UFC 3-210-10 requires retention of stormwater runoff from the 95th percentile storm using all known, available, and reasonable methods described in Section 3-3 Design Options for LID Features in UFC 3-210-10, including engineered natural treatment, engineered subsurface treatment, and non-potable rainwater harvesting, to the maximum extent

16

technically feasible (METF) unless otherwise directed. The Romanian Government civilian environmental authority has stated that stormwater infiltration is not allowed on the project site due to the presence of aircraft and the risk of aviation fuel spills contaminating the groundwater. As such, non-LID stormwater management options, including but not limited to sand filters, mechanical devices, and detention pipe systems must also be considered. Stormwater management practices that utilize standing or ponded water are prohibited in the area between Taxiways E, F, G, and H and the runway. Stormwater Base Bid Stormwater runoff generated by the project is to be conveyed to the future stormwater drainage system serving the MK-1 Railhead, Fuel Storage Facility, and Ready Building. The future stormwater management pond that receives discharge from this drainage system must be enlarged by the D-B Contractor under the base bid scope of work to accommodate the required runoff volume generated by the proposed facilities, estimated to be a minimum of 8,300 cubic meters (6.9 acre feet).

Optional Bid Item 4 -Alternative Stormwater Management Area If the future pond serving the future MK-1 drainage system is not available to receive proposed stormwater runoff, the D-B must connect all proposed stormwater drainage systems to a proposed stormwater management practice to be located in the northwest corner of the project, within the MKAB property boundaries, that is compliant with BASH requirements. Acceptable practices include but are not limited to a sand filter basin.

4.6. Earthwork General Requirements A limited subsurface exploration was conducted in May 2018 to support conceptual design. Physical soil character is indicated in the boring logs and test data in this RFP. The typical soil profile in the project area consists of topsoil, fill consisting of sand and building debris, and clayey silt (loess) soil. The D-B Contractor must dispose of soil excavated from the site in accordance with all HN laws and regulations a minimum distance of 1 km (0.62 mile) from the MOD property limits. The D-B Contractor is hereby notified that no borrow pit exists within the MOD property limits. Satisfactory materials comprise any materials classified by ASTM D2487 (similar to European Standard EN ISO 14688-1) as GW, GP, GM, GP-GM, GW-GM, GC, GP-GC, GM-GC, SW, SP, and CL. Materials which do not comply with the requirements for satisfactory materials are unsatisfactory. Unsatisfactory materials also include man-made fills; trash; refuse; backfills from previous construction; and material classified as Satisfactory which contains root and other organic matter or frozen material. The D-B Contractor must develop UFGS earthwork specifications based on the Government-provided geotechnical report and their own more detailed geotechnical study described in Section 7.0 of the RFP. Topsoil Material suitable for topsoil obtained from offsite areas and excavations is defined as: natural, friable soil representative of productive, well-drained soils in the area, free of subsoil, stumps, rocks larger than 25 mm (1 inch) diameter, brush, weeds, toxic substances, and other material detrimental to plant growth. Topsoil will be separately

17

excavated, stored, and used for surface finish in preparation for seeding, sodding, or other planting, only where topsoil is superior for grass and plant growth as compared with the remainder of the excavated material. The D-B Contractor must keep topsoil separate from other excavated materials, brush, litter, objectionable weeds, roots, stones larger than 50 mm (2 inches) in diameter, and other materials that would interfere with planting and maintenance operations. Existing Fill Based on the government-provided geotechnical report, the existing fill appears to have been placed without acceptable compaction or quality control and contains debris and possibly other deleterious materials. Where present, the debris appears to have created voids within the fill. Utilities and underground structures are also likely present underneath the fill. Based on the government-provided geotechnical report, the D-B Contractor must, at a minimum, remove all the existing fill beneath and extending at least 3 meters horizontally beyond the edge of any planned pavement, utility, or other structure. Fill must be removed to expose natural subgrade and confirm removal of rubble, existing foundations, utilities, underground structures, and other deleterious materials. There are various buildings and structures in the construction area as well as buried and stockpiled concrete and other debris. The debris and demolition materials may be disposed of at an acceptable off-site landfill. Disposing of these materials by burial in areas within the MK site is prohibited. Such material must be stored above-ground on site pending disposal. The D-B Contractor must consider utilizing segregated recycled concrete, brick, and mortar materials for select fill, pipe bedding, frost-resistant fill, sub-base, or general structural fill and must develop UFGS specifications for these materials with appropriate Quality Control criteria in accordance with UFC 3-260-02 and the limits in the applicable UFGS sections. Trenching and Excavation for Appurtenances The D-B Contractor must follow the trench excavation requirements of appropriate UFGS specifications. Rock, where encountered, must be excavated to a depth of at least 150 mm (6 inches) below the bottom of the pipe. Excavate pipe trenches as recommended by the manufacturer of the pipe to be installed. Shore trench walls more than 1.5 meters (5 feet) high, cut back to a stable slope, or provide with equivalent means of protection for employees who may be exposed to moving ground or cave in.

Provide excavation for manholes, catch-basins, inlets, or similar structures sufficient to leave at least 300 mm (12 inches) clear between the outer structure surfaces and the face of the excavation or support members.

Slopes Slope excavation and protection must follow the standard requirements of UFGS Specifications 31 00 00 Earthwork for all work on thesite and in borrow areas. The D-B Contractor must provide erosion and sediment control measures for temporary and permanent slope stabilization.

Excavation Support Systems The Contractor will have the responsibility for designing the trench shoring and sheeting system or obtaining a suitable trench box on all trench excavations over 1.5 meters (5 feet) deep or where it is known that in-situ soils lack the stability to hold near vertical faces. Where sufficient room is available and all UFGS conditions are met, the Contractor may

18

slope back trench walls rather than having to use a shoring system. The D-B Contractor must develop a shoring and sheeting plan which will accomplish the following:

Prevent undermining of pavements, foundations, and slopes

Prevent slippage or movement in banks or slopes adjacent to the excavation

Comply with all employee health and safety requirements

Subgrade The D-B Contractor must develop a specification for proof rolling in the appropriate UFGS specifications. Compaction requirements beneath all airfield pavements must follow UFC 3-260-02. Compaction requirements beneath roads must follow UFC 3-250-01. Soil data in the geotechnical report included as Appendix E yielded a Liquid Limit ranging from 31.6 to 38.6 and a Plasticity Index ranging from 15.5 to 23.4. Existing Utilities The Contractor must physically verify the location and elevation of the existing utilities indicated prior to starting construction. The Contractor must scan the construction site with electromagnetic and sonic equipment and mark the surface of the ground where existing underground utilities are discovered. Excavation made with power-driven equipment is not permitted within 600 mm (2 feet) of known utility or subsurface construction. For work immediately adjacent to or for excavations exposing a utility or other buried obstruction, excavate by hand. The D-B Contractor must relocate, improve, or protect any existing utilities that are impacted by construction of the project in accordance with all applicable standards.

4.7. Erosion, Sedimentation, and Dust Control Due to the prevalence of silty soils in the geotechnical data, erosion, sediment, and dust control may require a significant level of effort.

Erosion and Sediment Control The D-B Contractor must provide measures for erosion and sediment control for all aspects of the project, including but not limited to work limits, material storage and equipment laydown areas, field office areas, and haul roads. The D-B Contractor must include such measures in the project phasing plan drawings, keyed to the sequence of construction. Erosion and sediment control measures must be implemented in accordance with Romanian laws and regulations. Per UFC 3-201-01, if no erosion and sediment control requirements exist, an erosion and sediment control plan must be provided in accordance with the requirements of U.S. Environmental Protection Agency’s (EPA) Construction General Permit. Vegetation must be preserved to the maximum extent practicable.

The D-B Contractor must prevent erosion by all practicable means, including but not limited to mulching, compost blankets, geotextiles, and temporary slope drains. Slope stabilization methods must include chemical stabilization, sodding, seeding, or such combination of these methods necessary for effective erosion control. Use of hay bales is prohibited. Seeding must utilize native species of grasses in compliance with Romanian standards.

The D-B Contractor must implement sediment control practices to divert flows from exposed soils, temporarily store flows, or otherwise limit runoff and the discharge of pollutants from exposed areas of the site. Sediment control practices must be implemented prior to soil disturbance and prior to creating areas with concentrated flow, during the construction process to minimize erosion and sediment laden runoff. Devices including but not limited to silt fence, temporary diversion dikes, sediment traps, and storm drain inlet protection must be considered. Location and details of installation and construction must

19

be indicated on the drawings. Erosion controls must be low-profile and well-secured due to the proximity of construction activities to airfield operations.

Construction operations for dewatering must maintain compliance with Romanian laws and regulations, including water quality standards and anti-degradation provisions. The D-B Contractor must not discharge excavation water to the sanitary sewer, storm drains, or to surface waters without prior specific authorization in writing from the COR. Discharge of hazardous substances will not be permitted under any circumstances.

Dust Control The D-B Contractor must keep dust down always, including during nonworking periods. Acceptable methods of dust control include sprinkling or treating, with dust suppressants, the soil at the site, haul roads, and other areas disturbed by operations. Dry power brooming will not be permitted. Instead, use vacuuming, wet mopping, wet sweeping, or wet power brooming. Only wet cutting will be permitted for cutting concrete blocks, concrete, and bituminous concrete. Dust particles from construction activities, and processing and preparation of materials must be controlled always, including weekends, holidays, and hours when work is not in progress. The D-B Contractor must maintain excavations, stockpiles, haul roads, permanent and temporary access roads, plant sites, spoil areas, borrow areas, and other work areas within or outside the project boundaries free from particulates that would cause a hazard or a nuisance to aviation activities. The D-B Contractor must implement dust control measures in accordance with UFC 3-260-17 Standard Practice for Dust Control on Roads, Airfields, Base Camps, and Adjacent Areas. The D-B Contractor must provide sufficient, competent equipment available to accomplish dust and particulate control and must perform particulate control as the work proceeds and whenever a particulate nuisance or hazard occurs. Comply with Romanian laws and regulations.

4.8. Fire Protection Background and Existing Water Systems There is limited water supply distribution infrastructure in the project vicinity. The nearest known existing viable water system connection point is located approximately 1,000 m (3,281 ft) southwest of the project area, serving the U.S. Marines’ section of MKAB. Flow test data collected May 2018 are provided in Appendix G. Base Bid Water Supply The water supply connection point for the Base Bid is the water supply system serving the wash rack at the future Railhead Facility at the adjacent MK-1 project. The D-B Contractor must coordinate this connection through COR.

Optional Bid Item 2 – Alternate Water Supply If the Base Bid water source is not available, the D-B Contractor must connect to a hydrant at the existing water supply system serving the military installation located west of the airport discussed in Section 4.8.1. The D-B Contractor must coordinate this connection through the COR.

Optional Bid Item 3 – Alternate Water Supply If the Base Bid and Optional Bid Item 2 water sources are not available, the D-B Contractor must connect to the future water supply serving the future Ready Building at the adjacent MK-1 project. The D-B Contractor must coordinate this connection through the COR.

20

The Base Bid and Optional Bid Item water connections are shown on Sheets CG-102 and CG-103 of the conceptual drawings in this RFP. All investigations must be coordinated through the COR.

Fire Protection Requirements 4.8.5.1. General Fire Protection Requirements

Fire protection water service must be provided adjacent to the explosive cargo load unload apron, as required by Section 6-12.6.1 of UFC 3-260-01, and must be designed and constructed in accordance with all applicable UFC, NFPA, NATO and Romanian Standards. Fire protection work must include connecting to existing water supply, providing a new fire hydrant loop to accommodate new fire hydrants necessary to meet required fire flow and providing a complete and operable water distribution system for proposed airfield modifications. The D-B Contractor must coordinate any power connections with the Installation, the civilian airport, and with adjacent projects that may have spare capacity through the COR. The primary design references for fire pump installations are NFPA 20 Installation of Centrifugal Fire Pumps, and UFC 3-600-01 Design: Fire Protection Engineering for Facilities. Per Section 9-5.1.2 of UFC 3-600-01, fire pumps must be in a detached, noncombustible pump house or located in a fire-rated room in accordance with NFPA 20 with direct access from the exterior. The pump house must be protected by automatic sprinklers. The pump house must be located outside all aviation clear zones. Unless otherwise directed by the COR, the D-B Contractor must provide a back-up generator for the fire protection pump that must be critically silenced so that 71db are not exceeded 1 meter (3.3 feet) away and no hearing protection is required. Any generator larger than 300KVA will require a permit from the Romanian Government. The generator must be designed to provide full firefighting pressure in 2 to 3 seconds. The D-B Contractor must provide audible and visual alarms as required by NFPA 20 on the controller.

6.0 Environmental Requirements 6.1. Hazardous Materials

A Phase II Environmental Site Assessment (ESA) of the project area was contracted by USACE. The primary objectives of the ESA were to conduct environmental soil borings, install temporary monitoring wells, perform associated sampling of soil and groundwater, and conduct laboratory analyses on the collected samples. The ESA is included in Appendix F of this RFP. Based on the ESA, there is a possibility of hazardous materials still being present from previous use of the site, or that materials to be removed may contain hazardous materials. If hazardous materials are unexpectedly or otherwise found to exist, the D-B Contractor must immediately notify the COR, cease work in the area, and secure the site. The D-B Contractor must take precautions to protect the site from surface runoff and precipitation, and prevent leaching of any hazardous material in the surrounding area. The Romanian Government is responsible for all issues related to hazardous materials on the property and the D-B Contractor must coordinate through the COR.

Soils Soil analysis is the ESA did not reveal any Aromatic Hydrocarbons (AHC, including BTEX), chlorinated hydrocarbons (CHC), pesticides/herbicides, perfluoro octane sulfonate + perfluorooctanoic acid (PFOS + PFOA) or chlordane. PCB were detected in one sample at a concentration below the U.S. EPA MCL of 0.5 mg/kg. Single detects of TPH and/or PAH indicate that confined and isolated spot contamination may be present, especially within the fill material in the northern part of the site.

In soil, arsenic was consistently detected at levels slightly exceeding the U.S. EPA Carcinogenic SL of 3 mg/kg for industrial soil. The elevated arsenic concentrations are regarded as being of geogenic origin. For all other metals (lead, cadmium, total chromium, chromium VI, copper, nickel, mercury, and zinc), no concentrations exceeding the applied environmental trigger values were noted.

Groundwater Groundwater within the ESA investigation was only encountered within the shallow aquifer formed by sandy silts to silty sands. Due to the presence of siltier layers above, the groundwater is mainly confined and was encountered during the June 2018 sampling event at depths between 8.84 meters (29 feet) and 14.10 meters (46.25 feet) below ground surface (bgs). The ESA investigation confirmed the presence of elevated concentrations of various heavy metals exceeding environmental triggers in groundwater, but not in soil.

28

Building Materials The ESA investigation included the buildings to be demolished within the project area. Asbestos and lead were detected in some building component samples such as roofing and paint. The findings are in the ESA, which is included in Appendix F of this RFP. All demolition and debris handling, removal, transport, and disposal must be conducted in accordance with the Demolition Permit and all with all Romanian Government laws and Regulations.

Threatened and Endangered Species The ESA included an Endangered and Threatened Species Survey. Per Section 7 of the report, none of the plant species identified are subject to protection under Directive 92/43/EEC and the Romanian Law No 57/2011. Also per Section 7, multiple bird species protected under the Romanian Ordinance 57/2007 / Law No. 49/2011 and Romanian Ordinance 57/2007 / Law No. 49/2011 will be permanently impacted. As discussed in Section 3.0 of this RFP, the D-B Contractor must coordinate any permitting requirements through the COR. The Endangered and Threatened Species Survey is included in Appendix F.

6.2. Unexploded Ordinance (UXO) The Host Nation is responsible for verifying that the site is free of UXO. There is no prior knowledge of Unexploded Ordnance (UXO) material at the project sites described in this RFP. UXO scans conducted during the ESA and included in the ESA report included in this RFP did not detect UXO. If UXO material is unexpectedly or otherwise found to exist on the project site, the Contractor must immediately notify the COR. Once notified of UXO material, the COR must notify the appropriate authority which must then engage required measures for UXO clearance and unblock the concerned area for further construction work after clearance.
