Dolphin Cove Multipurpose Building & Pavilion

Durable and Resilient Construction for Modern Coastal Park Facility

The Opportunity

Isla Blan­ca Park sits at the very south­ern­most tip of South Padre Island, Texas less than 10 miles from where the Rio Grande Riv­er emp­ties into the Gulf of Mex­i­co. The park is the most pop­u­lar park des­ti­na­tion in Cameron Coun­ty with over 1 mil­lion vis­i­tors per year. Isla Blan­ca is a peren­ni­al Top 10 Texas beach” accord­ing to USA Today. The Dol­phin Cove mul­ti­pur­pose build­ing and pavil­ion was designed to host the­ater art, music, school, and band con­certs events to the area. The con­struc­tion of Dol­phin Cove was the first step in a mul­ti-year ren­o­va­tion and expan­sion pro­gram for Isla Blan­ca Park.

Con­sid­er­ing the pub­lic use of the build­ing, salt expo­sure from the ocean, and the ongo­ing risk of hur­ri­canes, the project team at Gignac Archi­tects focused on bal­anc­ing dura­bil­i­ty and resilien­cy with keep­ing the project with­in bud­get.

Key Design Features

The Bau­tex Wall Sys­tem was select­ed for all of the exte­ri­or walls of the build­ing with the excep­tion of the large glass sec­tions at the front. Bau­tex was also used on sev­er­al inte­ri­or walls to pro­vide addi­tion­al struc­tur­al capac­i­ty for the build­ing. The walls were coat­ed with the Bau­tex Air and Mois­ture Bar­ri­er and then fin­ished with Stuc­co­Max Exte­ri­or Wall Fin­ish and paint.

  • Bau­tex walls are the pri­ma­ry load bear­ing sys­tem for the build­ing.
  • Two of the inte­ri­or Bau­tex walls were designed and built to cre­ate moment frames that pro­vide the entire lat­er­al (shear) resis­tance for the struc­ture.
  • Designed and con­struct­ed for high­est wind zone (Sea­ward).
  • Sol­id mono­lith­ic walls with­out organ­ic mate­ri­als or wall cav­i­ties pre­vents mois­ture and mold prob­lems in this hot-humid cli­mate.
  • Abuse-resis­tant mag­ne­sium-oxide cement based stuc­co fin­ish sys­tem for impact resis­tance and long term dura­bil­i­ty in hash envi­ron­ment.


Fast Construction
Using the Bau­tex Wall Sys­tem accel­er­at­ed con­struc­tion by allow­ing a sin­gle con­trac­tor to build the struc­tur­al walls in one mobi­liza­tion.

Structural Simplicity
Bau­tex was able to pro­vide all of the struc­tur­al require­ments for the build­ing which sim­pli­fied both design and con­struc­tion.

Energy Efficiency
Con­tin­u­ous insu­la­tion, ther­mal mass, and tighter build­ing enve­lope result­ing in long-term ener­gy sav­ings.

Durability & Low Maintenance
Resilient mate­ri­als that are mold-resis­tant, low-main­te­nance, storm-safe and 4‑hour fire rat­ed pro­tect this impor­tant com­mu­ni­ty asset.



Bau­tex proved to be the most cost-effec­tive and fastest way to build the Dol­phin Cove build­ing con­sid­er­ing the harsh coastal envi­ron­ments and the coun­ty’s desire for a long ser­vice life. Spec­i­fy­ing Bau­tex sim­pli­fied the archi­tec­tur­al design and allowed the struc­tur­al engi­neer to ful­ly rely on the wall sys­tem to achieve the load­ings required for the project. Dol­phin Cove is the first of sev­er­al build­ings in Isla Blan­ca Park that are uti­liz­ing the Bau­tex Wall Sys­tem.
