Construction Considerations
From its earliest stages and Mississippi Aquarium's May 2018 groundbreaking, general contractor Roy Anderson Corporation (RAC) oversaw the construction project. Total estimated construction costs were $52 million of the Aquarium's approximate $100 million overall budget. Working closely with RAC, Roofing Solutions fabricated and installed the zinc flat-lock wall tiles on all three buildings using more than 81,400 pounds of RHEINZINK prePATINA blue-grey as supplied by Oakland Metal Sales.

"We worked hand-in-hand with the general contractor, the manufacturer and the supplier," said David Furr, Roofing Solutions' general manager for Mississippi. "It really was a joint effort to get it done. A massive amount of coordination was needed to keep everything working smoothly and safely."

Tupac De La Cruz, Roofing Solutions' operations manager, agreed and added, "This was our first time working with RHEINZINK and Oakland Metal Sales. Our approach was to study the material properties and availability. Since the project had a considerable size, materials' lead time and availability were key to us, so we had to work in close and constant communication. Both the manufacturer and supplier were in direct contact with us, with fast responses and solutions to every challenge this project represented."

According to Furr, "Thousands and thousands of panels were fabricated by our crew at our Prairieville (Louisiana) factory and then shipped to the jobsite in phases. The material was placed in covered storage on site so that our people in the field had the supply they needed to install 50 to 60 tiles each day."

Roofing Solutions estimated that 35 people from its company contributed to Mississippi Aquarium, including three or four people who worked on site for a full year.

Cladding Complexities
All of Mississippi Aquarium's three buildings feature RHEINZINK prePATINA diamond flat-lock wall tiles, fabricated and installed by Roofing Solutions in a scaled, offset, overlapping pattern. The rounded, guitar-pick form of the buildings are composed of three curved walls that splay outward as they rise.

"It gets bigger as you go up, and some of these walls are over 60 feet high," simplified EGH's Allen. "We didn't want them to feel too big and overwhelm visitors. When you're standing inside the park, everything should feel approachable."

He continued, "Because every building is a different size and slightly different shape, it took some strategic geometric planning to layout and scale the RHEINZINK panels appropriately. Each building's panels are custom-sized to make all of them look uniform in their overall massing. It's a forced perspective. Hopefully, you won't be able to notice the difference."

"We provided the zinc coils in three custom widths to make it easier for Roofing Solutions to fabricate the precise panel sizes with efficiency and minimal scrap," said Oakland Metal Sales' Steve Stetson.

"We have experience in projects that require cladding methods for wall panels, so this was not our first time using this type of pattern," noted De La Cruz. "Having the possibility to design and produce the panels and attachments in our own warehouse, having experienced crews that know their way around the machines we use, and their experience with different gauges and sources of materials we use for our roofing and wall panel projects, gave us an advantage in successfully producing and installing the wall panels at Mississippi Aquarium."

At four stories and 22,200 square feet, the Aquatic Wonders building is largest of the three and uses 24-by-24-inch zinc tiles. The mid-size, 13,600-square-foot exhibit building has 20-by-20-inch tiles that clad the entire façade include its parapet and dramatic canopy.

At 5,400 square feet, the smallest building uses 16-by-16-inch tiles to scale the ticketing area and Gulf Shop. Sheltering visitors from Mississippi's occasional rain, EGH inset the ticket windows and entrances, allowing the walls to provide an integrated covering. Where needed, Roofing Solutions fabricated custom trim, flashings and other detailing from the same RHEINZINK prePATINA material used to make the wall tiles.

Patina and Perpetuity
"We've been looking forward to working on a project with RHEINZINK for a long time," said EGH's Allen. "It's a homogenous material and it has a lifespan much longer than other products. Many other wall claddings – aluminum, prefinished metal, even stainless steel – would start to fade and pit after many years in these coastal conditions."

EGH's Allen also praised the material's aesthetic virtue and endurance. "The prePATINA zinc material begins with a consistent blue-grey color and, as it ages, its patina continues to gain character from the salt air and climate. They get more beautiful as time goes on. Similar to copper, it evolves instead of fails."

Allen estimates the life cycle cost of RHEINZINK's material, plus Roofing Solution's fabrication and installation, to be comparable to other metal cladding. He added, "Other than a little cleaning to keep the dirt off, there's hardly any maintenance. The longevity is what pays for itself."

"It was a big moment for me to finally be able to use a metal product that can last you more than 50 years, maybe even 100 years." EGH's Allen elaborated, "A lot of architects never get to design a project like this. I am very grateful for this rare opportunity. By the time I die, the zinc panels will still be serving their purpose."

Proven Performance
Remembering that, 15 years ago, Hurricane Katrina's flood levels topped at 24.5 feet, the elevation of the project site was raised to 25 feet and complemented by a seawall surrounding the Aquarium. Pumps and generators onsite also will maintain the care of the animals in the event of natural disaster.

Flooding, high winds, fade, corrosion and rust were all concerns expressed by the Aquarium's executive team, designers and contractors. EGH specified 1.0mm-thick RHEINZINK prePATINA blue-grey flat-lock panels to meet the project's multiple performance requirements. Tests were conducted to ensure the zinc tiles could withstand hurricane-force winds of up to 175 mph.

Ahead of the zinc material's installation, a plywood fire-treated exterior-grade substrate was set in place. Next a thick liquid waterproofing coating was applied, temporarily giving the structures an orange hue.

Roofing Solutions' field team anchored each zinc tile in place with sealed, concealed fasteners. "It's complicated and hard work, but it makes for great pull out strength, while sealing all the holes well. You should never have to remove the fastening clips, but if necessary, the tiles can be removed," observed EGH's Allen. "Roofing Solutions did an excellent job. Their installation looked better than our model, which is hard to do!"

Appreciative of the compliment, De La Cruz said, "This has been one of the most interesting projects we have had the privilege to participate on. We are truly grateful for the opportunity and proud of the excellent work of all our teams – from estimators, submittals team, and of course, our operations team, which supervised every detail from material purchase, transportation, fabrication, and final installation and touch ups."

Impressive Impact
Roofing Solutions' team members were counted among the approximately 400 construction jobs involved in creating the Aquarium, with 75% of this workforce coming from the Gulfport and Mississippi region.

Mississippi Aquarium is funded through a public and private partnership with 90% of the funding from City of Gulfport bonds, Mississippi Development Authority grants, Restore Act and Gulf of Mexico Energy Security Act (GOMESA) funds. The remaining 10% was contributed through by private donations to the Mississippi Aquarium Foundation.

"This is a win for the State of Mississippi and our Coastal region," stated the City of Gulfport Mayor Billy Hewes in a Facebook post. "There was a great deal of work by a lot of people in getting to this point. Commitments by the City and State, combined with partnerships with multiple agencies and universities, will result in a world class aquarium, which will advance tourism, economic development, research, and education initiatives for generations."

As a nonprofit 501(c)(3) organization, the Aquarium also supports community events, education outreach and partners with state and federal agencies to pioneer much-needed dolphin and marine research in the Gulf. Mississippi Aquarium seeks to empower the community to take action for conservation by connecting them to the aquatic world and participate in conservation events, beach cleanups and recycling initiatives.

"It is our obligation to provide our city, Coastal Mississippi and the entire state with an unparalleled aquatic experience – one that remains focused on our three pillars: education, conservation and community," echoed Allen, President and CEO of Mississippi Aquarium. "Each decision made is to ensure we are building safe habitats for our animals and creating experiences that will captivate our guests."

The care and welfare of the animals is the top priority as Mississippi Aquarium seeks to obtain accreditation from multiple industry institutions including the Association of Zoos and Aquariums (AZA), the American Humane Association (AHA), the International Marine Animal Trainers' Association (IMATA), and the Alliance of Marine Mammal Parks and Aquariums (Alliance). These accreditations will make Mississippi Aquarium the only fully accredited aquarium in the state.
