  1. Safe! The Renovation of a Century-old Warehouse into a Californian Ballpark Project done by Kieran Neary and Ricky Coombs

  2. Introduction An explanation of the steps taken to renovate an old Western Metal Supply Company building into a state of the art baseball stadium.

  3. Architects Working on this Project: -HOK Sport + Venue + Event (Kansas City, Kansas & Missouri) -Heritage Architecture & Planning (San Diego, California) -Antoine Predock Architect (Albuquerque, New Mexico)

  4. Background San Diego Padres decided to build a new ballpark. They wanted a site downtown near Gaslamp Quarter and the San Diego Convention Center. One site seemed perfect (in terms of location) Big problem: a historic masonry warehouse occupied site (designed by Sand Diego architect, Henry Lord Gay in the early 20th century) Building possessed industrial architecture that distinguished that section of San Diego so renovation of ballpark would have to preserve/reuse structure and its architecture.

  5. Process The process to renovate the original structure; a Western Metal Warehouse, consisted of four critical steps. -Assessing the existing condition of the presented building -Determining its gravity load capacity -Altering structure so that it could perform new functions -Seismically strengthening the building

  6. Framing Features: Gravity Framing System: -determined to be acceptable for project (would be able to support additions) Additions to Flooring: -First Level: filler beams -Upper Two Levels: timber beams added between existing beams (supported by sliding onto blocking into place above girders) *best looking

  7. -Structural Decking: -4” concrete topping poured over plastic sheeting protecting original wood (4” solid planks covered by 7/8” sheathing planks) Preservation Requirements: -Preservation of Old Beams *w/ modified additions mimicking old beams -Preservations of Roof *gradually lowered/flattened, new roof built above original- old roof hangs from new framing

  8. Specialty Framing Features: Subtractions: *Occurred where major new openings were required for ballpark functionality -floor openings for escalators (vertical steel tubes brace masonry piers against lateral loads tied back to floors to carry lateral loads horizontally across openings) -openings in walls for views of ballpark from planned suites (lintels added to ensure masonry was supported at all times)

  9. Additions: -ramps and landings (permit circulation between old and new flooring) -cantilevered balconies at each suite placed on two steel girders balanced on steel brackets connected to internal concrete posts.

  10. Requirements for Building (Seismic Design) -Renovation required to be designed in accordance to California Historical Building Code (1998) *seismic design must be based on forces equal to 75% of values established by 1995 Cal. Building Code Selected Design:-3 sided box- (3 walls with reinforced concrete liner) *leaves western wall exposed *wall openings on east, south, and north for max. amount of brick left showing

  11. -New concrete and steel posts added to meet requirements in 1994 Uniform Code for Building Conservation for URM walls

  12. -Cantilevers *made stronger/stiffer by truss work to avoid potential of and uncomfortable sensation of bouncing/instability (1997 Uniform Building Code seismic activity or value “R” requirement) Bridges connecting grandstand and garden buildings: -designed as cantilevers to grandstand in order to move freely at garden building side in earthquake *Other features effected by requirements: -precast stepped seating -pedestrian ramps

  13. Special PETCO Features -viewing spaces along fences -standing-room zones in grandstand -41,000 seats -60 suites -family-friendly venue including field for play and area designated for batting practice

  14. Seating Bowl *Seven Units: -(1) left field under scoreboard -(2) suites -(3-5) grandstand seats -(6) right outfield bleachers -(7) centerfield bleachers Garden Buildings: (behind home plate) -main concourse level -consist of lounges, kitchens, offices, and more Resulting gap forms boulevard

  15. Overall Design Motif Goal: -to capture ambiance of ballpark from the past

  16. In The Making
