A LAN connection shall not be installed for natural gas meters. No meters of any type shall be connected to a Direct Digital Control System on Dover AFB (i.e., Trane Tracer Summit).

1.9 System Maintainability Requirements. System maintainability is a critical aspect of a facility. Provide adequate clearances around all pieces of equipment for periodic maintenance, inspection and cleaning.

Provide manufacturer’s recommended minimum clearances or code required clearances, whichever is more stringent. System maintainability shall be coordinated between all systems. Service of one piece of equipment shall not require disturbance of adjacent equipment (for example do not block access to lights with piping or conduit). The designer shall reference ETL 01-1 “Reliability and Maintainability (R&M) Design Checklist” during design development to ensure system maintainability requirements are met.

1.9.1 System maintainability has three broad categories. The design analysis and O&M manuals shall address the following features/procedures in detail.

1.9.1.1 Routine Maintenance (filters, lights, lubrication, inspection, etc.) requires the most frequent and easiest access. Where maintenance access requires the use of portable ladders they shall be no more than 10’ maximum. Provide adequate space to use them properly. Access requirements over 10’ require ship ladders, stairs, platforms, catwalks, etc. unless approved otherwise by Dover AFB.

1.9.1.2 Component Replacement (coils, fans, motors, etc.) requires less frequent access.

However since this normally has the greatest impact on the facility user this work must be done quickly and efficiently. Provide all items necessary to perform these tasks (work platforms, equipment access hatches/panels, hoists, cranes, freight elevators, ladders, stairs, etc.).

1.9.1.3 Equipment Replacement (air handling unit, switchgear, boilers, heat pumps, etc.) requires the least access. Since this occurs very seldom the need for permanent equipment to support these tasks is not required. However, equipment replacement must be accommodated and the facility shall include items such as removable wall sections, access routes, etc. to allow replacement with the least amount of collateral damage.

1.9.2 All equipment, including filters, controls, control valves, backflow preventers, and coils shall be easily accessible and have ample room for servicing, inspection, and cleaning. Isolation valves shall be provided for each HVAC unit, zone, branch, long runs, etc. as necessary for proper isolation and maintenance. Coils shall be fully removable without requiring demolition of any building components. Piping configuration at all coils shall include unions to facilitate easy removal.

1.9.3 The design shall ensure that all maintenance and repair activities can be performed safely and efficiently without the need for extensive material handling (e.g. A-frames) or access equipment (e.g.

portable ladders over 10 feet).

1.9.4 Wherever possible locate all valves, pumps, strainers, controls, sensors, and other items requiring regular service such that they can be maintained from floor level. Provide permanent maintenance access where not accessible from floor level.

1.9.5 Coordinate locations of piping, conduit, etc., to avoid blocking access to cranes, hoists, ladders or similar items even if it necessitates longer runs of the pipe or conduit.

1.9.6 All above ceiling utilities (cable trays, ductwork, junction boxes, utility piping, etc.) shall be accessible for a worker to reach two sides plus the service side with a minimum 3'-3" (1 m) clearance (greater if required for component maintenance/disassembly).

1.9.7 Water treatment systems for boilers/chillers/geothermal systems shall be designed and installed such that chemical handling is accomplished at floor level.

1.10 LEED Requirements. Comply with Air Force Sustainable Design and Development (SDD) Implementing Guidance dated 02 June 2011 (see attached Appendix D). Attachments to the guidance memorandum are available upon request made to the DAFB Base Civil Engineer. The guidance states that all new vertical construction and major renovations shall meet the USGBC LEED 2009 Minimum Program Requirements (MPRs) as well as additional requirements. The designer shall evaluate the requirements of this guidance and how they pertain to a particular project before beginning the design process.

2.5.7 The temporary electric service connection source location for construction activities, including the requirement for a temporary transformer if needed, shall be shown on the project construction drawings.

2.6 Existing Groundwater Monitoring Wells: Existing groundwater monitoring wells located within the construction footprint shall either be abandoned in place or have the tops adjusted to new grade. If unable to be adjusted to new grade the wells shall be abandoned in place and replaced at an adjacent location approved by Dover AFB. DAFB will determine the necessary disposition of existing wells when identified during the design process and will provide specific monitoring well requirements to the designer for incorporation in project documents. The designer shall coordinate with the DAFB Environmental Management Office 436 CES/CEAN (302) 677-6842 for specific guidance on projects where monitoring wells are present at the construction site.

2.7 Excavation and Grading:

2.7.1 Site plans shall identify a project Benchmark which provides horizontal and vertical survey controls.

2.7.2 Whenever possible, project designs should endeavor to balance earthwork cut and fill quantities.

Existing soils which are suitable for reuse should be reutilized to the maximum extent possible to avoid the need and cost of removal from the site. Project estimates shall include estimated quantities of any existing soils which will necessarily need to be removed from the site.

2.7.3 Site plans shall show existing and new surface elevation contours for turfed and paved areas.

Spot elevations shall be provided for specific or critical locations, such as along drainage swales, at drainage structures, top of curbing, or breaks in grade.

2.7.4 Maximum slope of turfed areas shall be 4H:1V to facilitate mowing operations.

3.0 Environmental

3.1 Stormwater Quantity and Quality

3.1.1 In conjunction with the State of Delaware's regulations pertaining to sediment and stormwater, permanent stormwater quantity issues are only required if the project will increase stormwater flow at the associated outfall by 10%. Outfall definition is the point where stormwater discharges Dover AFB, not from the project site. Nearly all projects will be exempted from permanent stormwater quantity issues.

Designer shall inquire from Dover AFB which outfall the respective project will discharge to and whether the exemption is applicable.

3.1.2 In conjunction with the State of Delaware's regulations pertaining to sediment and stormwater, permanent stormwater quality issues are required to manage the first inch of runoff from each site. To satisfy this requirement, Dover AFB installed regional permanent water quality features at outfalls 003 and 007 (the two largest outfalls on Dover AFB). Nearly all projects will be exempted from permanent stormwater quality issues because of the regional features. Designer shall inquire from Dover AFB which outfall the respective project will discharge to and whether the exemption is applicable.

3.1.3 Sediment and Erosion Control: Temporary stormwater quantity and quality issues must be addressed on every project. The requirements for the inclusion of a sediment and erosion control plan on the project construction drawings shall be as required below.

3.1.3.1 For projects less than 5,000 square feet of total disturbed area, a sediment and erosion control plan is not required.

3.1.3.2 For all linear disturbance projects (such as direct buried utilities) not exceeding a 10 feet maximum width of disturbance (even if exceeding 5,000 square feet of total disturbed area) a sediment and erosion control plan is not required.

3.1.3.3 For projects over 5,000 square feet of total disturbed area or linear disturbance projects which exceed a 10 feet width of disturbance the project construction drawings shall include a sediment and erosion control plan. The plan shall be developed in accordance with the State of Delaware Department of Natural Resources and Environmental Control (DNREC) standards. The plan shall be titled “Recommended Sediment and Erosion Control Plan” and shall include the Dover Air Force Base

Sediment and Erosion Control Plan Notes. The specifications shall include specific contractor requirements as contained in the DAFB Standard Specification “Dover AFB Sediment and Erosion Control”.

3.2 Energy Policy

3.2.1 All construction shall comply with energy conservation standards set by latest version of UFC 3-400-01.

3.2.2 All new buildings and existing buildings undergoing major renovations to supply not less than 30 percent of the hot water requirements through solar heating if life cycle is cost effective to be in compliance with the Energy Independence and Security Act of 2007.

3.3 Termite Treatment: All new below grade and at-grade construction shall utilize materials which are not susceptible to insect infestation. Termite treatment is therefore not required and shall not be incorporated in project requirements.

3.4 Underground Oil Storage Tank Removal: Oil shall be pumped out and placed where indicated by the Government. Dispose of all residual waste (sludge), cleaning water (triple rinse) and clean tank (tank shall be rendered useless by punching holes in it or cutting into pieces).

3.5 Asbestos Abatement: Survey all possible materials (including floor tiles under carpet and determine number of layers of floor tile). Remove all asbestos materials unless approved otherwise by Dover AFB.

3.6 Lead-Based Paint Removal: It is usually more cost effective to demolish and dispose of lead-painted items than to remove paint from them. Survey all painted surfaces that will be affected by construction.

3.6.1 The U.S. Environmental Protection Agency (EPA) has issued new rules for contractors who renovate or repair housing, child-care facilities or schools built before 1978. Under the new rules, workers must follow lead-safe work practice standards to reduce potential exposure to dangerous levels of lead during renovation and repair activities. The “Lead: Renovation, Repair and Painting Program” rule, which will take effect in April 2010, prohibits work practices creating lead hazards.

Requirements under the rule include implementing lead-safe work practices and certification and training for paid contractors and maintenance professionals working in pre-1978 housing, child-care facilities and schools. Beginning October 22, 2009, contractors must take EPA-accredited training before beginning renovation, repair or painting projects as defined in the RR&P rule. The new requirements apply to renovation, repair or painting activities where more than six square feet of lead-based paint is disturbed in a room or where 20 square feet of lead-based paint is disturbed on the exterior. The affected contractors include builders, painters, plumbers and electricians. Trained contractors must post warning signs, restrict occupants from work areas, contain work areas to prevent dust and debris from spreading, conduct a thorough cleanup, and verify that the cleanup was effective.

3.7 Geotechnical Soil Borings. The designer must coordinate with the Dover AFB Environmental Management Office 436 CES/CEAN (302-677-6842) for specific guidance on all projects.

3.7.1 Permits. An AF Form 103 “Work Clearance Request” is required for all ground disturbing activities on Dover AFB including geotechnical soil borings regardless of depth. Additional permits are not required (including State of Delaware) for geotechnical soil borings drilled to a depth of less than 20 feet below the ground surface. For soil borings drilled to a depth of 20 feet or below from the ground surface, the drilling contractor must obtain a soil boring permit from the Delaware

Department of Natural Resources and Environmental Control (DNREC) in accordance with the Delaware Regulations Governing the Construction and Use of Wells. The soil boring activities must be accomplished by a State of Delaware licensed well contractor. The well contractor must complete the DNREC Application for a Permit to Construct Monitor, Observation, Recovery Well(s) or Soil Boring(s), attach a location map to the application, sign as the Water Well Contractor and mail or deliver it to the DAFB Environmental Management Office 436 CES/CEAN (302) 677-6842 in Building 600 for Property Owner signature. The mailing address for permit applications is:

436 CES/CEAN

600 Chevron Ave Dover AFB DE 19902-5600

The Dover AFB information required in the “Property Owner” block on the permit application is as follows:

Property Owner: Dover Air Force Base Address: 436 CES/CEAN, 600 Chevron Ave City, State, ZIP: Dover AFB, DE 19902-5600 Telephone Number: 302-677-6842

There is no DNREC permit fee for geotechnical borings. Well contractors should contact the DAFB Environmental Management Office 436 CES/CEAN (302) 677-6842 with questions about the permit application.

Upon receipt of the permit application, a Dover AFB representative will sign the application as the Property Owner and deliver it to the DNREC Water Supply Section for processing. DNREC typically requires 10 business days (2 weeks) to process applications. Soil boring activities cannot proceed until the well contractor has obtained the DNREC permit. The well contractor must have a copy of the permit on-site at all times during drilling activities. A copy of the permit will also be maintained by the DAFB Environmental Management Office 436 CES/CEAN (302) 677-6842.

3.7.2 Closing of Soil Borings

3.7.2.1 Geotechnical soil borings greater than 20 feet deep shall be sealed with concrete, Portland cement grout, sodium-based bentonite clay grout, or combinations of these materials. The boring must be filled with these appropriate sealing materials starting from the bottom of the hole upward to ground surface in accordance with the Delaware Regulations Governing the Construction and Use of Wells.

3.7.2.2 Geotechnical soil borings less than 20 feet deep should, when possible, have the cuttings from the soil borings placed back in the boring hole at the completion of the test. However, it may not be possible to place the soil back in the boring hole if the hole collapses, particularly when the boring hole penetrates the water table.

3.7.2.3 Soil cuttings that cannot be placed back in the boring hole (whether for physical reasons or because of sealing requirements for deep borings) shall be handled as described below.

3.7.2.3.1 For boring locations which are not within a known contaminated area the soil cuttings can be spread out on the ground adjacent to the boring location if such soil will not

1) be carried off the site through runoff during rain events, 2) be unsightly, or 3) have other adverse problems. This option is generally applicable in grassy areas, or already disturbed construction areas, but is not suitable for deep borings that generate a lot of soil cuttings.

3.7.2.3.2 For boring locations which are not within a known contaminated area and the soil cuttings cannot be spread out on the ground adjacent to the boring location the soil cuttings must be drummed or stockpiled. The cuttings will then be tested and disposed of by Dover

AFB.

3.7.2.3.3 For boring locations within a known contaminated area the soil cuttings must be drummed or stockpiled. The cuttings will then be tested and disposed of by Dover AFB. If drumming is not practicable the soil stockpiles must be placed on an impermeable liner and covered with an impermeable liner until testing and disposal can be accomplished.

3.8 Soil and Groundwater Disposal from Construction Activities

3.8.1 Current or past industrial activities associated with some facilities on Dover AFB create the potential for encountering contaminated soils or groundwater during project construction activities.

During the design process, Dover AFB 436 CES/CEAN will identify potentially contaminated soil and groundwater in the vicinity of the proposed project. Regardless, whether or not there is known contamination in the vicinity of the project, all projects that will have construction activities which necessarily encounter soil or groundwater need to have soil and groundwater disposal requirements appropriately addressed in the construction documents during the design phase.

3.8.2 The DAFB Standard Specification “Dover AFB Environmental Specifications” requires that during construction 1) all soils requiring disposal off of Dover AFB will be excavated and stockpiled and 2) all groundwater captured as a result of dewatering activities shall be contained in contractor furnished tanks on site by the construction contractor and then tested and disposed of by Dover AFB.

Project construction cost estimates shall include estimated quantities of existing soils and groundwater which will necessarily need to be removed from the site due to excess quantity or dewatering activities. The cost of soil and waste water testing and disposal by Dover AFB shall be funded with project funds and accomplished by contract through DAFB Environmental Management Office 436 CES/CEAN (302) 677-6842.

3.9 Recycled Construction Material: The specifications shall include specific contractor requirements for recovery or recycling of construction materials as contained in the DAFB Standard Specification “Environmental Specifications”.

3.10 Projects will not include oil-water separators unless approved by DAFB Environmental Management Office 436 CES/CEAN (302) 677-6842.

3.11 Where generators are a part of the project, they shall be designed to a capacity which efficiently accommodates the facility load. Generators shall also be designed to comply with State of Delaware Department of Natural Resources and Environmental Control (DNREC) permitting regulations pertaining to air quality, Regulation 1144 “Control of Stationary Generator Emissions”. The DAFB standard Specification “Environmental Specifications” contains specific requirements for the construction contractor to coordinate with DAFB Environmental Management Office 436 CES/CEAN (302) 677-6842 to obtain a generator permit.

4.0 Landscaping

4.1 All landscaping shall comply with Dover Air Force Base: Architectural Compatibility Plan. See changes to ACP in Section 5.1 of this document.

Designs shall utilize xeriscaping to the maximum extent possible, using low- to no-maintenance plants, vegetation, and ground cover.

Xeriscaping is a comprehensive landscaping program that emphasizes water conservation.

4.3 Turf Establishment: Projects within the industrial or housing areas of the Base shall require sodding and not seeding for both general turf establishment and repair of existing turfed areas. In general, seeding shall be used for turf establishment within airfield areas, except sod may be necessary in areas subject to jet blast. The project specifications shall be edited to require turf establishment by the contractor to include 1) temporary irrigation as necessary based on rainfall conditions, and 2) mowing to a maximum height of 6 inches until an approved stand of turf is achieved and accepted.

4.4 Turfed areas isolated by curb from adjacent paved surfaces shall be provided with curb depressions to permit access by riding mowers. Handicap accessible curb ramps can serve this additional function.

Consider the use of landscaping stone as an alternative (such as at parking lot islands).

4.5 Permanent underground irrigation systems shall include a tracer wire adjacent to the system piping with additional detectable warning tape above, reduced pressure backflow preventers and automatic controls including rain sensors.
