The article “Adaptive Reuse is Even more Sustainable with LEED”, on page 41, shows you how to meet your green goals; while “Don’t Treat Buildings Like Lifeless Objects” (page 44) discusses adaptive architecture — reminding architects that the past holds a plentitude of potential, which can be reimagined, reconfigured, and re-molded to suit present needs and concerns. We’re also offering our tried-and-true square-foot cost studies of renovation projects and adaptive reuse submitted by your peers. Camp Bow Wow, featured on the cover, is one of these new cost studies. (See pages 12−14.) As North America’s largest pet care franchise, with 200 locations in 40 states and Canada, the Camp concept has provided the highest levels of fun, safety, and service for its Campers — and peace of mind for their pet parents. The Camp features live web cams so parents can check in on their dogs. Some other projects covered in this issue include: • An open atrium of a university that was finished with an ETFE system in a “Harp” form features 38 two-layer cushions utilizing clear transparent ETFE film, allowing students and visitors to see the sky from under the roof. The system is an open-air structure, enabling air flow and ventilation around the perimeter of the structure (pages 7−8). • A library that occupies a prominent triangular site on a fast-moving thoroughfare, adjacent to storefront churches and small businesses. The project design includes a large plaza with public art, seating, and a grove of trees (pages 30−32). • The Business and Information Technology Building at a state university that is a 58,000-square-foot sustainable structure that allows students pursuing separate degrees to learn side-by-side and collaborate in multidisciplinary teams similar to the business world (pages 46−47). • The new two-story high school that embraces the school’s mission of prayer, study, community, and preaching by providing a framework for both collaborative and individual academic study and reflection (pages 37−39). All these studies include square-foot prices for divisions and regional cost trends to help you convert the total project cost to your area. Thank you for choosing this issue of Design Cost Data.

Unfortunately, the intrusion of water migrating through it — which was never designed to occur (the building originally had plans for a canopy) — has led to an abundance of maintenance and occupancy issues. While views to the sky have become commonplace and any alternative proposal is considered incorrect and/or inappropriate, this opening presented the Brooks+Scarpa Architects / KMF Architects design team with serious life safety hazards during rain events. The building was originally completed in 1979, and in that time has seen several renovations to try and fix the leaking that has persisted over 40 years. Water intrusion from wind-driven rain events caused many life safety and maintenance issues. The design team was asked to avoid the use of a canopy and look at other options. However, it became apparent that various slab, storefront, and stair systems would need to be extensively remodeled — at a cost double that of a canopy. Thus the canopy became the option of choice, and an extensive public engagement plan was implemented to go over solutions and field concerns. The original design included a canopy that was solid, and all building users advocated for the openness of the existing space. Rain screens and other elements were considered, but the designers realized that wind- driven rain exposure would continue to be an issue. The team went through an exhaustive process of “designing for designers”, where multiple solutions were considered beyond the placement of the canopy. However, the cost impacts far exceeded the cost of a canopy, therefore a solution was sought that would balance remediation efforts and maintain a visible connection to the sky. The opening itself is an irregular form, a combination of three trapezoids, which created interesting opportunities when designing a potential covering. The design team presented three categories of options: skylight systems, ETFE systems, and solar arrays.

Solar arrays over the entire atrium opening were presented with varying densities, allowing unique solutions, but did not allow enough daylight into the space. ETFE solutions using single or dual layers became the preferred /September-October 2022 7 The ETFE system with a “Harp” form was selected as the design solution to the water issue.

PROJECT INFORMATION8 /September-October 2022 choice, and could provide daylight, rain coverage, wind load criteria, self- cleaning performance, and insulated/ passive cooling design options that were lightweight and could be supported by the existing structure. Ultimately the ETFE system with a “Harp” form was selected as the final solution, and the design team moved forward, working with the construction manager and manufacturer to develop the design solution and construction documentation. The form takes its cues from the building geometry to elegantly and seamlessly blur the addition to give a sense that it was always there. The “Harp” features 38 two-layer cushions utilizing clear transparent ETFE film, allowing students and visitors to see the sky from under the roof. The system is an open-air structure, enabling air flow and ventilation around the perimeter of the structure. The new canopy uses five existing column touchpoints and end shear walls to distribute weight and load over the existing structure, thus minimizing costs and giving the visual perception that the canopy is floating over the atrium. The canopy was fabricated from standard structural steel sections, and connections/fasteners were carefully detailed to be concealed and hidden. This approach further allowed the canopy to visually “disappear” within the space. The assembly and construction took less than two months on-site, which diminished downtime and closure of the building and allowed it to stay open and accessible through the process of installation, while minimizing disruptions to the active and bustling campus. The system is an open-air structure, enabling air flow and ventilation around the perimeter of the structure. The “Harp” form takes its cues from the building geometry to blur the addition elegantly and seamlessly. 716-633-9500 | sales@birdair.comBirdair.comPhoto Courtesy: Sonoma State University Owner Sonoma State University For more information on this project and similar projects visit www.dcd.com DIVISION COST % OF SQ.FT.
