Design Analysis

1.3 DEMOLITION

The Tool and Die Facility will be in a yet undeveloped part of the Iowa Army Ammunition Plant.

The site is mostly flat without obstructions so limited demotion is anticipated. Another building is currently being constructed next to the site. Small demolition of the proposed concrete paved areas is anticipated in order to make connections to concrete paved areas for this project.

Removal of small tress is planned for the installation of utilities.

1.3.1 Disposal of Materials

All demolished materials will become property of the contractor and shall be removed from government property.

1.4 SITE PLANNING

1.4.1 Force Protection

Guidance is provided in UFC 4-010-01. A standoff distance of 40’ was initially proposed.

However, it was decided to implement the revised UFC and remove the standoff requirement.

1.4.2 Pedestrian Circulation

The Tool and Die facility will be located in an area separate from any other building besides the new Metrology lab currently under construction. Minimal pedestrian circulation is anticipated.

Sidewalks will be provided between the main building entrance and the Metrology Lab’s entrance and around to the east and north sides of the facility where a maintenance access doors are located.

6’-wide mown paths will be provided in absence of sidewalks where habitat area is proposed to achieve the Open Space LEED credit.

1.4.3 Parking

Per SDDCTEA Pamphlet 55-17, the typical parking space dimension is 18.5’ in length by 9’ in width. 18 spaces have been provided for general POV parking, one of which will be a designated ABA accessible space. 11 spaces have been provided for the Metrology Lab, closer to the main entrance of the proposed facility.

Parking lots will be constructed of concrete pavement with concrete. The fire department access road behind the facility will also be constructed of concrete.

1.5 GRADING AND DRAINAGE

The building site is located in a generally flat area. The finished floor elevation of the new facility will be approximately 3’ above the existing grade. The primary considerations behind the development of the grading plan were ensuring positive drainage away from the building while maintaining the ability to connect to existing storm drain infrastructure, in addition to matching finished floor elevations with the proposed metrology lab.

To account for potential consolidation of the subgrade, overexcavation in the general footprint of the building has been recommended. The details of this operation are found in the Geotechnical Report.

Drainage is accomplished mostly by sheet flowing off of pavement and impermeable areas. Roof drainage from the Tool and Die Facility will be discharged on the ground away from sidewalks

Iowa Army Ammunition Plant, IA

Design Analysis and will sheet flow away from the building. In addition, There is a stormwater infiltration basin (pond) that will collect runoff from the site. The basin is designed to completely capture the first 1” of rainfall from impermeable areas in order to achieve LEED credit. The outlet of the pond is set at an elevation that will capture this volume.

Drainage for the road will be accomplished by sheet flow to adjacent turfed areas and drainage ditches.

1.6 PAVEMENT DESIGN

Roadway pavement will be mostly concrete Pavements will be designed to accommodate the expected traffic of small passenger vehicles and will also be based on design life and existing sub-base soil conditions of the site. A geotechnical investigation and report has been prepared for this project. The proposed pavement sections shown in the plans are based on assumptions from nearby previous projects and will continue to be refined later in the design process.

Proposed pavements are planned to be high reflectivity pavements. This is for the achievement of LEED credit for heat island effect reduction.

1.7 TRAFFIC SIGNAGE AND STRIPING

Traffic signs and striping conform to the Manual on Uniform Traffic Control Devices (MUTCD).

1.8 LANDSCAPING

1.8.1 Ornamental Shortgrasses

Ornamental shortgrasses are to be seeded in difficult-to-mow areas (slopes exceeding 15%) to reduce landscaping maintenance. These areas are also designed to count toward the vegetation requirement of the Restore Habitat, Rainwater Management, and Open Space LEED credits.

1.8.2 Pollinator Garden

A pollinator garden is to be seeded in the bioretention area in order to achieve the Restore Habitat, Rainwater Management and Open Space LEED credits. Furthermore, a mounted 12x18” sign and picnic table are to be provided in the pollinator garden to help meet the Open Space LEED credit.

1.8.3 Trees

Trees are included in landscaped areas to achieve the Restore Habitat leed credit. A temporary underground bubbler irrigation system is to be provided to water the trees for their initial survival.

The system is specified to be shut off after the two-year establishment period in order to achieve the Outdoor Water Use Reduction LEED credit.

1.8.4 Lawn

Lawn areas are to be seeded with the turfgrass mix specified by the Iowa AAP natural resources manager.

1.9 EROSION AND SEDIMENT CONTROL

The total area disturbed by construction is 14 acres. An NPDES permit for stormwater discharges from construction sites is required.

1.9.1 Permanent Erosion and Sediment Controls

Permanent erosion and sediment controls include the following:

Iowa Army Ammunition Plant, IA

Design Analysis

Seeding

All areas disturbed by construction and not otherwise surfaced are being seeded. Seeding of grass will provide stabilization to the soil by holding the soil particles in place.

1.9.2 Temporary Erosion and Sediment Controls

Temporary erosion and sediment controls such as silt fences, earth dikes, drainage swales, sediment traps, check dams, temporary seeding, etc. shall be selected by the Contractor and included in the Contractor's Stormwater Pollution Prevention Plan to be prepared as part of the NPDES permit for stormwater discharges from construction sites.

4 INTERIOR DESIGN

4.1 DESIGN OBJECTIVE

The intent of the Interior Design is to provide an aesthetically pleasing, comfortable, functional and easily maintainable working environment for the occupants. The Interior Design will include coordination of the exterior and interior finishes and materials, including selection of color, texture, and pattern, in addition to the preparation of building finish specifications, which will include window treatment and interior signage.

4.2 FINISHES AND COLOR SCHEME

The interior finishes will be selected to simplify maintenance and operations, maximize flexibility and assure long-term appearance retention. In addition to considering finishes and materials with recycled content, low emitting and rapidly renewable materials will be considered to assist in complying with sustainability requirements. Color, texture and pattern within the facility create continuity and interest, are visually pleasing and easily maintainable.

4.2.1 INTERIOR COLORS

The interior color scheme will be carried throughout the facility, but slight changes help differentiate between various functional areas within the facility. These variances can be seen in subtle color and pattern changes within the facility.

Color and pattern will be introduced in porcelain tile, solid surface material, plastic laminate, and furniture finishes to help hide soiling and provide visual interest. Floor patterns may be located in long corridors to help visually shorten their length.

4.2.2 EXTERIOR COLORS.

See the Architectural DA for information on exterior building finishes and colors.

4.3 FURNITURE

A furniture floorplan has been developed utilizing generic furniture sizes and is provided for space planning purposes. A Furniture, Fixtures and Equipment (FF&E) design will also be provided for this project. The FF&E will be Contractor Furnished/Contractor Installed (CF/CI) and be included as a bid option in the CLIN schedule as a separate line item.

5 STRUCTURAL

5.1 SCOPE OF WORK

Refer to Part 1 – General Project Information.

The objective of this project is to construct a new facility located outside of an explosive arc to improve resiliency and worker safety, increase operational efficiency, and reduce costs, while supporting all production programs and expanding capabilities. New equipment will be procured and installed into the new facility to align with long term industrial base strategy of modernizing, improving readiness, and surge capacity. Inert Plastic Lab will be located inside the Tool and Die Facility.

The Tool and Die facility and Inert Plastics Lab will include multipurpose rooms and areas, such as

Inspection room Welding room Grinding room Mechanical room Electrical room Fire Riser room Air Compressor room General shop area – tool and die Tool room 3D printing room Communication room Magna-Flux room General shop area – inert plastic lab Hot room PDR. PRC. Room Material Room Offices and restrooms

The building will be a single-story steel structure with insulated panels used as cladding for walls and roof. Partition walls could be masonry and cold form steel. The building will host multiple function equipment and multiple crane capacities.

Based on the soil investigation, ground improvement is required under the foundation system.

The foundation system consist of shallow spread footings, combined footings, and mat foundation. Some areas inside the building such as the storage area, and forklift pathway will need special slab considerations as it will be exposed to heavy loads as well as the lightweight equipment. The remaining portions of the building will have relatively normal loads and will not need the same special considerations.

5.2 DESIGN CRITERIA

Refer to 5.2.1 for a complete list of the design criteria used for this project. Tool and Die Facility planned, designed, and constructed in compliance with IBC 2021 (IBC) and ASCE 7-16, and as supplemented by UFCs 1-200-01, 3-301-01, 3-320-06A, and ACI 302.1R-15, as well as other UFCs and Standards.
