Summary: The Des Moines Fire Department Maintenance/Logistics and Training Campus project is designed to provide a 46,000 square foot centralized location for apparatus and equipment maintenance, department operations, and training of personnel. Currently, maintenance and training operations take place at separate sites that do not allow for adequate space and efficiency for these activities. The project cost is estimated at $9.6 million and scheduled to begin in spring 2011. Scope of Review – Board to make recommendation to City Council on:

Design review of renovation /remodeling/new construction for City-owned or leased project Design review for urban renewal project with specific development requirements Whether a proposed urban renewal project qualifies for funding from tax increment. Whether the level of financial assistance funded from tax increment revenues proposed for a specific

individual project are reasonable and appropriate. The selection of urban renewal sites for clearance or rehabilitation and problems relating to acquisition,

clearance or rehabilitation of property, relocation of displaced persons and disposition of acquired property. Skywalk System Other

Urban Design Review Board Action: The Board is asked to make its recommendation to City Council regarding the proposed design for the fire training and logistics facility. Staff Recommendation: Staff recommends approval of the preliminary design. Final approval has also been requested by the project representatives and is supported by staff, pending review and comment by the board. Background: The Mulberry Street Fire Station (#1) was constructed in 1933, and currently houses multiple operations for the Des Moines Fire Department, including maintenance and administration. Training activities for department personnel currently take place at the former Lomar building, which was acquired by the City of Des Moines as part of the MLK Jr. Parkway extension project. To provide needed space for training and logistics, and centralize and enhance maintenance operations, the City acquired a site at 2715 Dean Avenue to construct the Maintenance/Logistics and Training facility.

URBAN DESIGN REVIEW BOARD AUGUST 31, 2010 AGENDA PAGE 2

The one and two story building will include classrooms, apparatus training bays, maintenance space, supply and distribution warehouse and administrative offices. The one story space consists of training and maintenance bays with overhead doors accessible to Dean Avenue on the north side of the facility and SE 28th Street on the east. The two story space consists of administrative offices, training support and classroom space. Building materials consist of a pre-engineered metal frame, and an exterior material surface combination of burnished block, brick veneer, metal panels, glass and aluminum storefront and curtain wall systems. The design team has worked to scale the building mass appropriately for the residential neighborhood to the north and east of the site. Energy efficient heating and cooling has been designed, including a geothermal system. The project will be submitted to the US Green Building Council upon completion for LEED evaluation and certification. A copy of the current scorecard for the project’s LEED components is included with this agenda item; the preliminary result reaches a Silver Certification, but will be further evaluated as the project moves forward. Please see the detailed narrative and design details included with the agenda item for additional information.

 

Des Moines Fire Training and Logistics Facility

Owner: City of Des Moines

Project Architect: OPN Architects / CR Architects

Project Schedule: Bid in spring 2011--Completion in summer 2012

Estimated Cost: $10.5 million

Introduction

The new Fire Department Training and Logistics Facility is an approximately 46,000 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 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

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.

The exterior of the building is a combination of burnished block, brick veneer, 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 openings spatially 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.

Energy Efficiency & HVAC

The main heating and cooling for the building shall be provided by geothermal heat pumps and in-floor radiant tubes. Ventilation for these areas shall be through the outside air damper integral with the unit. The kitchen shall have hoods over the cooking equipment. A dedicated outdoor air makeup unit shall provide the necessary makeup air for the hoods. A demand control sequence shall be use to conserve energy. The Training and Maintenance bay shall not be provided with air conditioning, however will utilize natural convection ventilation

Sustainability/ LEED

A planning session was held to discuss the preliminary results and options most likely to be pursued by the City of Des Moines. This meeting was attended by representatives from the City of Des Moines the Fire Department and the design team. The meeting was lead by the design team and was an overall discussion of the City’s expectations for the facility. Presently, the project has set a goal for “certification” as represented by a score of 40-49 points under the “Yes” column. Currently, the preliminary result of the LEED scorecard analysis has the project at a “Silver” level with 50-59 points. Each of the strategies identified will be examined in more detail (along with many of those in the “Maybe” column) as the design develops. Upon completion of the project, the design team will make a submission to USGBC for evaluation and certification.
