Safe!The Renovation of a
Century-old Warehouse into a Californian Ballpark
Project done by Kieran Neary and Ricky Coombs
Introduction
An explanation of the steps taken to renovate an old Western Metal Supply Company building into a state of the
art baseball stadium.
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)
BackgroundSan 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.
ProcessThe 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
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
-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
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)
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.
Requirements for Building
-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
(Seismic Design)
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
-New concrete and steel posts added to meet requirements in 1994
Uniform Code for Building Conservation for URM walls
-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)
*Other features effected by requirements:
-precast stepped seating
-pedestrian ramps
Bridges connecting grandstand and garden buildings:
-designed as cantilevers to grandstand in order to move freely at garden
building side in earthquake
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
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 moreResulting gap forms
boulevard
Overall Design Motif Goal:
-to capture ambiance of ballpark from the past
In The Making
The Finished Product
Home Run!
