3-1-00 Design Requirements
NIH campuses are developed to provide pleasant environments for the enhancement of the research. An important part of this environment is the campus-type setting with attractive landscaping and a minimum of paving. The important research conducted at NIH requires the support facilities to be constructed to the highest standards available in the industry to minimize disruption caused by repair and reconstruction. The Office of Research Facilities has prepared campus Master Plans for buildings as well as underground utility services. These plans shall be followed.
New buildings or additions shall be coordinated with the OFP and located in conformance with the NIH Campus Master Plans.
• Preserving existing natural features such as trees, slopes, and drainage characteristics, whenever possible. 
• Providing vehicular/pedestrian access that blends with the existing traffic pattern. 
• Providing access for emergency vehicles, including fire and police.
• Phasing construction projects that impact day-to-day NIH activities to minimize disruption to the campus.
• Identifying contractor staging areas and reasonable space provided for contractor parking, various trailer types (including storage, materials and office), dumpsters, cranes, delivery vehicles, maneuvering, and other site-specific factors. 
A.  Reference Codes and Standards
The A/E shall use and comply with the design and safety guidelines, and references listed in Appendix A, and other safety guidelines received from the NIH Project Officer or as required by the program.  The A/E shall utilize the latest editions of reference design and safety guidelines available at the time of the design contract award.
The following standards shall be followed when constructing new structures on NIH campuses.
• NIH Campus Master Plans in locating new campus facilities
• NIH Master Utility Plans in locating existing campus utilities
• NIH Tree Inventory
B. Publications:
American Society of Civil  Engineers publications provide the de-facto project standards regarding Civil Engineering.

3-1-10 Design Guidance
A. Grading: 
Proposed grading plans shall be coordinated with ORF.  Maximum slopes on lawn areas shall be 3:1.  A retaining wall with a safety railing shall be provided for any slope greater than the maximum defined slopes for lawns.  Minimum slopes on lawn areas shall be 2% positive slope away from buildings.  Maximum slopes of sidewalks shall not exceed 8% unless approved by the ORF.  Standard 50mm pipe railing, with an intermediate horizontal stile, painted black, shall be installed when the slope exceeds 5 percent.  Slope limitations and rest points shall comply with ABA.
A.1 Stockpiling:
Stockpiling is strongly discouraged, however may occur on a project-by-project basis, if in compliance with all of the following conditions:
• Prior approval from DEP
• Excavated material quantities less than 76CM
• Excavated material stored within the limits of disturbance (LOD) 
B. Sediment and Erosion Control:
Sediment and erosion control (SEC) drawings shall be prepared for construction that results in ground disturbance in states or local jurisdictions, where required. NIH policy regulates on-campus SEC to the maximum practicable extent. Any construction that results in ground disturbance shall be subject to the NIH SEC protection policy, on a project specific basis.  The Project Officer shall contact the DEP for specific guidance.  The A/E shall prepare SEC permit drawings and submit to DEP through the Project Officer for review. 
C. Storm Water Management
To ensure proper water quality, all drainage systems that collect runoff from parking areas shall be provided with appropriate exterior-type oil, sand, and grease interceptors to serve segregated waste streams for specific functions as necessary to ensure compliance with EPA discharge regulations, and minimize potential maintenance issues for NIH campus infrastructure.  Drainage from intermediate parking garage levels shall discharge to sanitary through an appropriate oil/sand interceptor. Only the top deck, exposed to rainfall, may discharge to the storm water system.

3-1-20 Design Information & (Local Requirements)
A.  Reference Codes and Standards
The following standards should be followed when constructing new structures on NIH campuses located in Montgomery County, Maryland:
• Maryland Department of Transportation State Highway Administration Standard Details for installation of storm drains
• Washington Suburban Sanitary Commission for installation of domestic water and sanitary sewer
• Montgomery County Department of Transportation, Standard Details for Roadways, for installation of roadways, parking, and miscellaneous appurtenances
• Maryland Department of Environment (MDE), Standard Details for Sediment Control and Storm Water Management
B. Sediment and Erosion Control:
For NIH projects located in Maryland, when a project nears or exceeds the Maryland Department of the Environment (MDE) threshold defined as a disturbance of 465 m2 of existing ground or the movement of 76 m3 of soil, an MDE permit for SEC is required.  SEC projects with greater than 4,000 m2 of disturbance shall comply with MDE General Permit Number 97-GP-0004, which requires additional inspections.  Additional fees, record-keeping, and other requirements may also apply.
All submittals prepared by  the A/Es to the MDE for state plan review and approval MUST be made by the NIH/DEP for projects on the Bethesda and Poolesville campuses. It is highly recommended that an MDE review be made through an MDE-approved “expedited” reviewer.  No site work shall commence prior to holding a SEC preconstruction meeting with the MDE inspector when a permit is required.  When a permit is not required, the installation of SEC required by DEP shall be in place before site work begins
C. Storm Water Management:
All construction shall meet the requirements of the MDE and the NIH Master Plan for storm water management. 

3-1-30 Design Document Requirements
A. Site Development Plan
Plans profiles, details based on existing topography reference to project benchmarks, metes and bounds surveys and storm water calculations showing but not necessarily limited to: location of building(s), roads, service areas, major site features, easements and other legal constraints, set backs etc.
B. Sediment Control Plan:
Plans and details showing erosion control measures.
C. Outline Specifications
Outline specifications shall be developed at the design development stage
D. Detail Performance Specifications
Detail performance specifications shall be developed at the contract document stage.
E. Systems Cost Estimates
Systems cost estimates shall be developed at design development stage.
F. Quantity Takeoff Estimates
Quantity takeoff estimates shall be developed at the contract document stage.
