This report, prepared by OPN Architects, Inc. and CR architecture + design (formally Cole + Russell Architects) describes in detail the design intent for the site, architecture, structural system, and mechanical/electrical/plumbing systems.

Items of Note:-Elevations are conceptual and have been included for reference only. They will continue to be explored, for form, materiality and day lighting opportunities through the Design Development stage. -Schematic cost estimate reflects Option 1 in the HVAC narrative. Option 2 (Geo-Thermal system) will be explored and priced in the Design Development stage.

Project Overview The new Fire Department Training and Logistics Facility is an approximately46,000 gross square feet, one and two story building. The estimated project cost is $9.6 million.The facility will be located in Des Moines Iowa on the northeast corner of a site bordered by Dean Avenue to the north, 28th Street to the east, light industrial to the west and a rail yard to the south, a residential neighborhood to the north and east with a former fire station occupying the SE corner of Dean and 28th. The site is generally flat with some adjacent slope off-site to the south to the railroad tracks. The grades under and around the footprint of the building will need to be raised to maintain positive drainage away from the building.The former site was a Perelli-Amstrong tractor tire finishing and tubing factory, of which portions were demolished in 1984 and 1989. Upon demolition and abandonment of the site remedial action was performed circa 1995 to remove various contaminants, receiving clearance for future development in August of 2008.


2.0 Site Narrative


Topography and Stormwater Management

A detention area for the site will be located west of the main building. Anexpected detention volume of approximately 30,000 cubic feet will be needed for the site if a majority of the on-site flows can be routed to the detention area. The stormwater from the roof will be piped into a storm sewer system and routed to the detention area. The detention outlet will be tied to the City of Des Moines storm system in Dean Avenue.

The required erosion control measures will be taken to ensure water quality throughout construction. A stormwater management plan will be required for the site as an NPDES permit through the State of Iowa DNR.

Site Utilities The existing water service will be tapped from an already present 8” main located on the north side of Dean Avenue on the north side of the site. Any water service stubs fronting the site must be cut at the main if they are not going to be used for this project. Three stub locations are present on the east side of the site along E. 28th Street.

System Development fees through Des Moines Water Works are required for both the domestic and fire services and are based on size.

Fire hydrants are currently located on the north side of Dean Avenue near the center of the site and on the southeast corner of the intersection of Dean Avenue and E. 28th Street. Additional hydrants may be required on site according to the building code.

An existing sanitary stub from the sanitary main in Dean Avenue is located approximately 200 feet west of the northeast property corner. Potentially, this may be utilized for the building connection to the City of Des Moines sanitary main. If this is unavailable for connection, sanitary connection will need to be made at the sanitary main in the center of Dean Avenue. Another possible sanitary connection is located under E. 28th Street. Floor drains connecting to the city sewers are required to be protected by an approved sand and oil interceptor.

Existing overhead electric service is located on the north side of Dean Avenue, the east side of E. 28th Street, and on the property in the southeast corner. Contact Mid American Energy in regards to the service routing and required sizes and what is available through each existing line.

The existing gas main is located on the north side of Dean Avenue. Contact MidAmerican Energy in regards to the service relocation and any permitting that may be required.

3.0 Architectural Narrative


Architectural Overview The proposed design consists of pre-engineered metal building frames with custom skins, along with more traditional construction types skinned with metal panels and brick veneers. The associated building types and forms help reduce the building mass into a more appropriate scale for the residential scale of the neighborhood. The facility includes fire department administration offices, spaces for training such as classrooms and multipurpose areas, as well as spaces for the maintenance of fire apparatus and equipment. The building is designed for the future expansion of both the apparatus and maintenance bays.

The building contains 5 main program elements – 1. Administration offices, 2. Training bays with training support, 3. Classroom spaces, 4. Maintenance bays with maintenance support spaces, and 5. Warehouse component. The training bays consist of a large, open, single story space that provides access to Dean Avenue via multiple overhead doors. The administration offices, training support and classroom spaces are located within the two story portion of the building that is positioned to connect the training bays to the maintenance facility. This area is located at the intersection of Dean Avenue and 28th Street and provides the primary entrance into the facility. Like the training bays, the maintenance bays are a large, open, single story space that provides access to 28th Street via multiple overhead doors. The maintenance support spaces are directly adjacent to the maintenance bays and include a two-story warehouse space.

Exterior Design The exterior of the building is a combination of burnished block, brickveneer, metal panels and glass and aluminum storefront and curtain wall systems. The training and maintenance bays are both pre-engineered metal frames with exterior custom skins, burnished concrete masonry unit (cmu) base and insulated metal wall panels that intern form the sloped metal roofs. Glazing is incorporated in the overhead doors along with translucent panels at the upper portion transoms to provide natural day lighting into these spaces.

The two story Administration area contains administrative offices and support spaces, training support and classrooms. Construction is conventional steel structural framing with first floor concrete slab on grade; second floor concrete slab on metal deck; and roof constructed of membrane roofing, insulation and low slope metal deck. Exterior walls consist of insulated metal stud framing with burnished block and brick veneer.

The Administration Block is divided in the east/west direction by an architectural “Spine Wall” element that “slides” vertically and horizontally through the building. The wall serves to define and organize spaces along the primary circulation route. On the first floor, classrooms are on the north side of the wall with support spaces on the south. On the second floor,office spaces are to the north with support spaces primarily to the south. A similar wall perpendicular to the Spine Wall terminates the block and separates it from the training functions farther west. The walls are expressed on the exterior by extending beyond the perimeter walls and roof of the Administration Block. They will be clad in metal panel siding to match the maintenance and training bays serving to visually tie together the different functional areas of the building. The walls on the interior along the

corridors will become gallery space to display artifacts and photographs depicting the fire department’s history. Periodically along the main Spine Wall, openings are present through the second floor. These openingsspatially connect the two floors and allow natural light to penetrate to the first floor corridor from above.

Entrance and vertical circulation are celebrated with two story aluminum frame and glass elements at the main entrance and east and west stairs,complementing the spine wall element. A full height glass “seam” at the midpoint along the North Elevation corresponds with the Break Room on the first floor and the primary open office area on the second floor affording daylight and views to a large portion of the building. The masonry exterior of the Administration Block is further punctuated with individual aluminum framed windows, corresponding with interior spaces.

Interior Design The interior finishes of the training and maintenance bays, along with a majority of the support spaces, are painted exposed structure and sealed concrete floors. Interior partitions are painted concrete masonry with hollow metal doors. The locker rooms/restrooms have epoxy painted concrete masonry walls, suspended acoustical tile ceilings. Classrooms and offices have painted gypsum board walls, carpeting, suspended acoustical tile ceilings, and solid core wood doors. The break room has painted gypsum board walls, vinyl composition tile flooring, andplastic laminate cabinetry.

8.0 Sustainable Design Narrative


Introduction The sustainable design goal for the project is to earn a LEED® Silver Rating, [i.e. between 50 to 59 points] in the LEED Version 3 rating system. The Design Team – including architects, engineers, landscape architects, and owner’s representatives- has reviewed the LEED requirements as they apply to this project. This group identified which LEED requirements were clearly applicable to the project at minor cost, which credits were not applicable, and which credits might be feasible but would require further study and possibly significant additional cost. In the scoring table that follows, those LEED requirements that are applicable and can be achieved with no cost or at minor cost to the project are shown in the “Yes” column; those that add significant cost or require further investigation are shown in the “Maybe” column. The team will examine the Maybe category of credits over the course of design and prepare cost estimates for each. Costly credits with negligible benefits to the owner or the environment will be rejected, those with promise will be included in the design.

The Design Team’s first goal is to establish a list of credits that achieve 52-58 LEED points to pursue the achievement of the project goal: Earning a at a minimum LEED Silver Rating. Through the course of developing contract documents and during construction, the team anticipates that earning one or more of these credits may prove to be impossible; one or two credits may be rejected by the LEED reviewers during the actual certification process.Currently, the Design Team is anticipating a LEED Silver Rating of 54credits with 16 variable, or alternate, credits that could be included depended on their cost of implementation.

The following paragraphs highlight the Design Team’s approaches for earning credits in each of the LEED categories. A table listing each credit that is being considered is located at the end.

Sustainable Sites The site was selected not for the purposes of the LEED evaluation, however, because it was previously developed, there is potential for Sustainable Sites LEED credit 3 Brownfield Development. The facilitydesign preserves many existing trees and has the ability pursue the restoration of natural habitat. Irrigation systems will not be needed due to the use of only native and hardy plant materials.

Parking spaces will be provided to meet the programmatic needs and minimum zoning requirements of the City of Des Moines. Bicycle parking and preferred parking spaces for low-emitting and fuel-efficient cars and car-pooling will be provided. An exploration of pervious pavers for site parking and approaches, along with high Solar Reflectance rated roof on the building will help reduce the heat island effect.

Storm water runoff will be minimized through the use of on site detention.

Lighting will be carefully designed to minimize light pollution.

Water Efficiency The vegetation on the site will be native or adapted to local climate requiring no irrigation system. Inside the building, water use will be reduced by water-conserving faucets, showerheads and urinals. The use of rainwater andcondensate water for flushing toilets was investigated and was found to be unfeasible for the project.

Energy & Atmosphere A variety of energy saving strategies will be employed to reduce energy use by over 26% compared with ASHRAE 90.1 2004. Enhanced commissioning will cover mechanical systems, lighting and daylighting controls, along with life safety and fire suppression systems. Other features that may beincorporated are refrigerants that reduce global warming and stratospheric ozone depletion, on-site renewable energy systems, metering equipment to monitor energy end-uses and green power purchase.

Materials & Resources Recycling of waste during building operations is being planned for by providing space for recycling storage and pick-up. Through the development of a construction waste management plan, 75% of the construction waste may be diverted from landfills. Specifications will require significant use of architectural materials with recycled content, and materials manufactured within a 500 mile radius. For the wood products in the building, the design team is considering the use of FSC certified wood for more than half of the wood and wood products in the building.

Indoor Environmental Quality Daylight, views, and low Volatile Organic Compounds (VOC) finish materials form the pillars for indoor environmental quality in this building. The building is being designed to provide daylight to 75% of the regularly occupied spaces and views to the outside for 90% of the regularly occupied spaces. During construction, materials will be stored in a certain manner thatprevents moisture damage, the air handling equipment will be operated with proper filters; after construction, the building will undergo a two-week flush-out just prior to occupancy. Interior finish materials will be specified to have strict limits on the emissions of VOC. The mechanical system will meet ASHRAE standards for ventilation and comfort.

Innovation & Design Process

Regional Priority

The sustainable design consultants are LEED Accredited Professionals, as are some other members of the Design Team. The desired innovation credits will likely be attained by pursuing credits SS 5.1 “revitalized prairie,”and SS 6.1 “drafting wells.”

Regional priority credits that have been identified for the area and are applicable to the project include: Site Credits 4.1, 4.2, and 6.1 and Materials & Resources Credit 2. An additional credit will be awarded for each of the specified credits once they are achieved.
