After the Blast, Oklahoma City Builds

Before the bombing, the city had enterprising plans to draw attention to its downtown. Now those plans matter more than ever.
by Mark Alden Branch

expert-interview-progressive-arch-magazine-mapsFor Oklahoma City’s boosters and business leaders, the April bombing of the Alfred P. Murrah Federal Building was a grotesque parody of their wildest dreams.  For years, residents of this 106 year-old city had struggled to develop an image for their low profile community. Then, just when an ambitious downtown improvement program was about to get under way, the world’s attention was seized by the grisly devastation of the Federal Building.

Nonetheless, the series of projects initially aimed at drawing attention and tourists to downtown Oklahoma City is going forward, and has gained new importance in a metropolis trying to move past its recent tragedy.

Oklahoma City’s plan, known as MAPS (for Metropolitan Area Projects), will use the proceeds of a temporary one-cent sales tax increase to build $285-million worth of public facilities, mostly downtown.

Where previous urban renewal plans in this city of just under $1 million have collapsed under their own weight, this one will succeed, civic leaders say, because the money to implement is assured.

The bombing and its widespread damage to buildings on the north side of downtown will have little effect on the plan, which is concerned mainly with downtown’s south edge.  However, city officials are considering new planning efforts for the area hardest hit by the explosion.  This summer, the National Endowment for the Arts is paying for a charrette that will bring in planners, architects, and artists to consider the future of the bombing site and the area immediately surrounding it.

expert-interview-progressive-arch-magazine-maps2The General Services Administration, which owned the Murrah Building, will have the final say over what is done on its site, but public sentiment runs strongly toward building a memorial there in lieu of a new building.  The GSA may decide not to rebuild at all, but instead relocate federal offices into existing downtown office buildings.

In Pei’s Empty Footsteps
The MAPS plan was conceived so as to avoid the fates of earlier forays in urban renewal, which nearly killed the downtown. The city implemented the demolition phase of a 1964 master plan by I.M. Pei, but didn’t follow through with much new construction; facilities such as a downtown mall were planned but never built.  The demolition left gaping holes in the central business district and, just east of downtown it wiped out an entire African-American neighborhood.

The city did manage to build a trio of new attractions on the downtown’s south edge: John Johansen’s celebrated Mummers Theater of 1970 (recently renovated and renamed the Stage Center), the Crystal Bridge botanical garden by Conklin Rossant (P/A, March 1989, p. 92), and the Myriad Convention Center.  But the disappearance of retailing, the development of an air-conditioned tunnel system, and the proliferation of vacant lots have conspired to turn a formerly diverse downtown into a dispiriting office zone. Foregoing the heroic task of comprehensively remaking the downtown, the current strategy concentrates on a series of individual projects it is hoped will spur spin-off investments around them.

“The projects are kind of like anchor stores in a mall,” says Jim Bruza of master plan architects Frankfurt Short Bruza.  “The areas between them will become good sites for private development.”

The largest chunk of new sales tax money will go for an $80-million sports arena intended to attract a National Hockey League franchise.  (The city’s Blazers have the best attendance record in the minor leagues.)  The minor-league baseball team, the 89ers, will get a new $23-million ballpark in the Bricktown warehouse district east of downtown.  The WPA-era Civic Center Music Hall will be renovated at a cost of $37-million, a new $15-million central librar y will be built, and the Myriad Convention Center will receive a $30-million renovation and addition by the local firm Glover Smith Bode with Thompson Ventulett Stainback & Associates of Atlanta.

A Canal to the Canadian River
An especially tough problem was how to lure conventioneers across the elevated railroad tracks that separate the convention area from Brictown, where brick warehouses have been transformed in recent years into an entertainment district.  The solution, inspired by San Antonio’s Riverwalk: create a below-grade canal.  The canal will originate in front of the convention center, pass through a portal under the tracks, and trace the route of a Bricktown street to the ballpark which is to be designed by ADG of Oklahoma City with David M. Schwartz / Architectural Ser vices of Fort Worth.  At the ballpark – which, attentive to the example of the Baltimores’ Camden Yards stadium, incorporates an existing warehouse into it’s design – the $15-million waterway will make a 90-degree turn and meander toward the Canadian River.

The canal, with walkways, trees, and outdoor cafes along its edges, will lie 14 feet below grade, presenting opportunities for converting Bricktown basements into an additional level of retail or entertainment space.  If the corridor develops as envisioned by Frankfurt Short Bruza, it will spawn a lively succession of activities alongside the canal and above it at the main level of the renovated warehouses.  Sheltered by the street walls of the warehouses, the canal could be an oasis in a downtown that is often hot, dry, and windy.  The canal will be convincing, however, only if its accompanying stairs, ramps, and terraces respect the dignity of the plain, muscular warehouses.

Planners harbor no illusions about the level of urbanity that Oklahoma City can achieve; the master plan document drily acknowledge that “a plan for a dense pedestrian city like Rome of Florence would be a mistake.”  Substantial retailing and housing are all but gone from downtown, and city officials don’t expect them to come back except in the form of specialty stores and residential loft conversions in Bricktown.

Like many Western cities, Oklahoma City came of age with the automobile.  Its 20th-Century patterns of development – which have resulted in a population density lower than that of any other U.S. city – make it unlikely that a traditional dense urban character can ever be created within its 604 square miles.  Instead, learning from theme parks, atmospheric ballparks, festival marketplaces, and other tourist lures, the new plan arranges attractions to create a pedestrian environment of a different kind – one based on special events rather than on daily routines.  Whatever Oklahoma City’s downtown may not be, it will be a destination – for conventioneers, for tourists, and, more than in recent years, for its own far-flung populace.

Design with a Purpose

Delivering a new helicopter maintenance hangar at Naval Air Station North Island overcame numerous design and schedule challenges in addition to the project being selected to test the Early Contractor Involvement acquisition strategy.

By Gene O. Brown, P.E., LEED AP BD+C, M.SAME, and Dusty Stoabs, P.E., CxA, CPMP, LEED AP BD+C, M.SAME

At Naval Air Station North Island, Calif., near the end of a long first day in a weeklong programming and design charrette, the design team prepared for its last appointment. The public works officer was to give his vision for the new, three squadron MH-60 Helicopter Maintenance Hangar. He spoke to the rich and storied heritage of the installation and its visual relationship with the City of San Diego.

With inward views from San Diego Bay, yacht clubs and San Diego International Airport, this new hangar had to be worthy of its location. It was to be a significant part of the base’s image and a source of Navy Pride. It had to be functional, efficient, and durable, achieve LEED Silver and be completed within budget. Moreover, Naval Facilities Engineering Command (NAVFAC) had selected the hangar to test the Early Contractor Involvement (ECI) delivery method. The challenges, some known that first day and others that emerged throughout the process, would prove to be significant.

Ultimately, however, teamwork and ingenuity delivered a successful outcome, achieving the project’s many goals, including elevated sustainability ratings introduced midway through—all despite operating in this “new normal” fiscal environment.

PROJECT UNDERWAY
NAVFAC began soliciting for an ECI contractor to come on board at the midpoint of the design phase and Architect and Engineer of Record Frankfurt-Short- Bruza (FSB) set to work incorporating the expressed needs of all stakeholders. The project, in addition to aesthetic challenges, met significant budget obstacles early on in design. The site was located on a thick layer of sand over another thick layer of bay deposits. It was determined to be liquefiable during a seismic event. The squadrons also needed previously unaccounted for space to properly function.

As the concept design moved into design development, these and other challenges were resolved through innovative team solutions. To mitigate the soil issues, engineers determined that stone columns offered both overall site improvement and higher facility performance, with a reduced cost over a traditional driven pile solution. They also utilized buckling restrained braces to reduce the effect of seismic events and temperature change on the structure. The net project savings more than paid for the upfront increased cost. Architects worked with engineers and installation maintenance personnel to design equip- ment platforms in the high bay space. This opened up the additional floor space each squadron needed. Outdoor spaces were created on both levels to provide open air seating areas and break spaces, again freeing up needed space in the facility.

DESIGN ELEMENTS
Considerable time was spent on facility aesthetics. Architects wanted to control the visual scale of this large facility, disguise its industrial nature and provide strong features. Most prominent are the naval aviation-themed entry elements that create both a material and spatial hierarchy, and clearly delineate the land-side points-of- entry. The massing of the facility on the land-side was broken up to create a softer rhythm across its 640-ft front face, creating space for more operable windows, daylight and outdoor areas.

The air-side of the facility presented a separate set of aesthetic challenges. Architects developed a curved roof profile to sculpt the high bay’s boxy volume and visually transition to the lower administration and shop space. A second curved feature added over each squadron’s hangar doors rolled back up over the roof to resemble stacked waves. These features contained a recessed backlit squadron insignia and served to break up the massive volume of the hangar bay. Translucent insulated panels in the vertical zone of the trusses make the roof appear thin, and at night, give the appearance it is hovering over the lower walls. During the day, the translucent panels permit significant diffuse daylight into the hangar bay and daylight sensors regulate light fixtures. Vertical lifting fabric doors were selected to eliminate the area required for door pockets, and columns between squadrons were minimized to create the effect of one continuous opening.

Through team collaboration, innovative solutions and identification of bid options, the project team delivered a design development submission that was tracking on budget and on time.

It was at this 60 percent design level when a newly adopted Navy policy increased the requirement from LEED Silver to Gold. Additionally, the project site was increased by approximately half and the construction budget was cut 2 percent. NAVFAC’s Design Manager also lost much of his supporting professional staff and the team learned the ECI contractor could not be added to the team until the pre-final design submission. In response, the entire design team reviewed cost estimates and created prioritized lists aimed at minimizing the impact of these new challenges. The User Group representative coordinated with his aviators and made timely decisions. Public Works took on the demolition of several existing buildings on the expanded site and the NAVFAC Design Manager covered the gap left by his loss in support staff while maintaining his role as the Navy’s design lead.

The change to LEED Gold required an additional 10 points. As LEED is very regimented in its precise execution, it is not perfectly suited to all projects. For example, enhanced commissioning by a third party and brownfield redevelopment were already part of the project, but they could not contribute points because they could not be executed in the manner required by the rating system. This necessitated that other potential credits be developed and prioritized based upon estimated cost.

At the pre-final design phase, the ECI contractor, Hensel Phelps, joined the team. They were already familiar with the base and their impact was immediate. Contractually speaking, this was no longer an ECI project. But the team embraced the collaborative spirit of ECI delivery and worked to blend the final design and early site package. And since all bid options were strongly desired by the project stakeholders, the ECI contractor was encouraged to come up with cost saving and quality improving proposals. To increase creativity, the contractor’s proposed recommendations were not required to comply with federal design standards. The notion being, if a proposal had merit, it would be considered.

SUCCESSFUL EXECUTION
Over a four-month period, the design team considered 58 separate value management proposals—from $900,000 credits to $300,000 additions. FSB performed technical reviews and made recommendations.

One particular point of interest was that even with the facility’s amplified aesthetic nature, it was predominately the expanded site that pushed budget limitations when compared by line item to the project’s DD Form 1391. Even so, a significant portion of the value management proposals focused on the aesthetics. These design elements were not the reason the budget was being pushed, they were just the most visible. Staying focused on the charge to be creative and reflect a sense of pride in naval traditions and naval aviation, the team delivered final contract documents with all bid options and stakeholder input incorporated, as well as the aesthetic elements intact, with only a 1 percent growth from the original construction estimate. The ECI-type collaboration effectively served to transfer design intent from FSB to the contractor and to clarify subcontractor questions as bids were finalized.

The results speak for themselves. Total change orders subsequent to the final contract documents were well below 3 percent, the majority of which were field requested design changes or unforeseen conditions. The facility was completed on time, in December 2013, and it will benefit mission accomplishment, improve readiness and enhance occupant performance for years to come.

 

 

A Tailored Approach to Energy Savings for College Campuses

As higher education budgets tighten and environmental consciousness grows, university administrators are turning to the mechanical engineers of FSB now more than ever in search of solutions for reducing energy usage and lowering monthly utility costs. The historic buildings and sprawling campuses that characterize many higher learning institutions require huge amounts of energy, but appropriately adjusting or upgrading heating, cooling and lighting systems can quickly lead to six-figure annual savings.

The key to maximizing savings, FSB Principal Brian Sauer said, is a highly individualized approach beginning with an interview with the client and a thorough building walk-through, followed by careful analysis to guide a decision-making process.

“Most people think they can simply apply something they read in a trade publication, and it’s not that simple because every building and campus is so unique,” Sauer said. “My goal is always to thoroughly evaluate each structure, understand its function and present models to the client before making any decisions. It is so important to evaluate where the most energy is being wasted and determine which adjustments offer the best return on investment.”

To predict potential energy savings, FSB’s team of mechanical engineers reviews utility bills, lighting and print-outs from chillers and pumps, which offer insight into the amount of energy each piece of equipment regularly uses. Based on their assessment, FSB can accurately model the buildings’ existing systems and predict how adjustments might affect energy usage.

For example, the firm was hired to replace the WWII-era boilers and 30-year old chillers in Oklahoma State University’s old central plant, which provides steam and chilled water for buildings throughout campus. FSB’s engineers began the project by creating a campus utilities master plan to understand how the buildings were performing and determine where on campus the plant should be located. They also factored in buildings slated for construction to predict heating and cooling needs as far as 20 years into the future.

“For Oklahoma State, adding on to the existing plant would not be as cost-effective as building a new plant because of the added energy efficiency a new plant could provide,” Sauer said. “It is so critical to have a campus evaluated by a professional engineer so money can be spent wisely. We can make sure the rate of return is there.”

Oklahoma State broke ground on its new plant in September 2015, and Oklahoma State Director of Energy Services James Rosner said when the project is complete and the plant is powered on the university will begin to save $350,000 annually in utility expenses alone, and about $120,000 in reduced annual maintenance expenses as the new equipment will require fewer repairs.

“The more efficient equipment, the refined procedures, and the technology that’s being put in — we’re going from WWII surplus equipment to cutting-edge technology,” Rosner said. “We’re being brought into the twenty-first century.”

In addition to the initial efficiencies, Rosner said the central plant designed with the future in mind — to accommodate the campus’ anticipated growth. The building includes space where the university can add additional heating and cooling equipment without requiring a renovation.

Administrators at another Oklahoma university, Oklahoma Christian University in Edmond, reached out to FSB in 2006 with a similar need — to keep buildings consistently cooler, conserve energy and reduce the campus’ monthly utility expenses. Oklahoma Christian didn’t have a central plant at the time.

After studying the school’s energy usage, FSB found that consolidating the campus’ heating and cooling equipment to one location would reduce the utility bills related to heating and cooling by about 40 percent, or about $500,000 per year.

“We knew Oklahoma Christian was planning to start construction on a large new dorm building and calculated that if we switched them over to a central plant, all the energy for this new dorm would essentially be free, because the amount that we were saving was more than that building would use,” Sauer said. “After we got the central plant installed and followed up with them, they said ‘That’s true. We use so much less energy than we did.’”

While renovating or reconfiguring heating and cooling systems is one strategy that, when appropriately applied, can bring major utilities and maintenance savings, this is one of many tools FSB’s mechanical engineers might recommend to a client. Others include ground source heat pumps, LED lighting, solar panels and automated controls. The team has worked to improve efficiency in buildings for many industries, as well as in many parts of the world. Sauer said each project begins with understanding factors like size of maintenance staff, age and composition of a building, and usage. For example, on a college campus a lab has very different needs than an administrative office. Even the geography and climate where the building is located is a factor.

“Solar panels make a ton of sense for some of our projects in California,” Sauer said. “They get plenty of sun, energy is more expensive, and you don’t have four-inch hail stones damaging panels every two or three years like we would in Oklahoma. Our engineers work all over the world, and every day we are exposed to different types of technology and utility rate structures.”

The art, Sauer said, lies in understanding the client’s unique needs and determining which technology is the best fit.

Myriad Botanical Gardens Reopens with Day of Celebration

OKLAHOMA CITY (September, 2011)

A daylong celebration marked the reopening of the renovated Myriad Botanical Gardens. Events included concerts, a farmer’s market and pumpkin patch, free admission to the Crystal Bridge, and a butterfly release. The 28,000 square foot gardens are located in the heart of downtown Oklahoma City.

city-of-okc_myriad-gardens_garden-stairs_okc-ok

Frankfurt Short Bruza (FSB), an Oklahoma City-based architecture and engineering firm, served as lead architect and engineer for the building projects in association with Gensler during the yearlong renovations.

“As a longtime Oklahoma City firm, it’s been an honor to lead the renovations of a true landmark like the Myriad Gardens,” said Allen Brown, principal at FSB. “The dramatic transformation of the gardens creates more inviting open space with a restaurant, state of the art water features, and sculptures all complemented by the natural surrounding beauty. Already visitors are enjoying the gardens, and we expect many more for generations to come.”

The new design provides a community gathering space for arts, entertainment, culture and botanical education. The Great Lawn and Performance Pavilion now holds up to 2,500 visitors and will host events like concerts, outdoor movie screenings and seasonal festivals. The new Water Stage provides an incredible outdoor stage with theatre seating for 500.

As part of the renovation, FSB marked their 65th anniversary with a $50,000 donation for the acquisition and placement of 65 trees in the Myriad Gardens. Each oak and cypress tree marks a year in business in Oklahoma City for FSB.

“FSB sees this donation as a commitment to future generations of Oklahomans,” said Brown. “The trees are a symbol of strength, sustainability and endurance. This donation is near and dear to our hearts at FSB, as we have been dedicated to the community for more than six decades.”

The trees now line the Great Lawn and Performance Pavilion area of the gardens. A permanent plaque was dedicated to commemorate the donation.

Emergency relocation — Smart, functional design on a tight timeline

FSB stepped up to help the Oklahoma Department of Tourism expedite its office relocation into the Department of Commerce building when the agency was given five days to vacate its current offices. The FSB team worked with Tourism and Commerce staff to successfully plan and execute the move in just one weekend.

The Situation: Relocation time-frame moved up two months on short notice
It was a Friday evening in late August 2015 when Deby Snodgrass got the call triggering what would be a weekend of “controlled chaos” for the Oklahoma Departments of Tourism and Commerce, both agencies for which she is the executive director.

Since June, the Department of Tourism had been working with FSB on relocating from its offices at the First National Center. The four state agencies with offices in First National planned to leave by the end of the 2015, and Tourism was on track to move all 100 of its employees by November.

That plan was thrown off course on Friday, August 21, when Governor Mary Fallin’s chief of staff called Secretary Snodgrass with news that her department would need to make an emergency move — utilities would be shut off at First National in five days.

“Fortunately for me, I knew exactly who to call for help,” Snodgrass said. “Secretary of Finance Preston Doerflinger, Secretary of Transportation Gary Ridley and FSB. Together with our outstanding teams at Commerce and Tourism, we launched into action first thing on Saturday morning.”

The Solution: A relocation schedule compressed from weeks to daysOK Department of Tourism Conference Room
Tourism had already narrowed down its options to a shortlist of locations, one of which was within the Department of Commerce’s building. Snodgrass believed the proximity would promote collaboration between the two departments. With a compressed timeline, the decision was quickly made and a charrette held Saturday morning to plan the move of two large state agencies — Commerce had to consolidate to the second floor at the same time that Tourism was moving onto the first.

“We fit into one day what would normally take place over several weeks,” said Fred Schmidt, FSB’s principal on the project. “Employees had to be able to show up at their offices, pack up their stuff, find their new desk on a map and get to work. Tourism oversees 60 state parks, a weekly television show, a bimonthly magazine and much more. They couldn’t miss a beat.”

Snodgrass said she welcomed relocation as an opportunity to modernize and streamline the Tourism offices. FSB had already taken a thorough inventory of all furniture and equipment, including the Discover Oklahoma studio, that would be moving to the new space. FSB interior designer Lauren Nash had been studying how the seven divisions within Tourism interacted with each other to determine how best to create the new layout.

“For the office to function well we needed to understand their operations,” said Nash. “This is what we’ve been trained to do as designers and planners, and it becomes a mental checklist of everything we know we need to ask the users. Then the adjacencies begin to appear so that they have a very functional and flowing office.”

From the beginning of the project, the goal had been to design a work-space that would set employees up for success, simplify their workflows and allow for future growth and flexibility. Even with a short timeline, long-term functionality was paramount. Four months later FSB is putting the finishing touches on the workspace, adding conference rooms and adjusting thermostats and lighting to give employees more control over their environment. But the bulk of the relocation happened during just a few days in August.

The Result: Modern, streamlined offices that enhance efficiency and collaborationOK Department of Tourism Reception
“FSB exceeded my expectations in every way,” Snodgrass said. “They worked all weekend and at night. They were willing to do whatever it took to reconfigure the space, ensure fire codes were observed and meet the time deadlines. The short time fuse definitely presented a unique set of challenges – but I am always ready to tackle the impossible. Where there’s a will, there’s a way.”

Now Snodgrass said she is watching the two agencies, Tourism and Commerce, become a blended family.

“Every day people are discovering new ways to work together to reach our common objective of creating and delivering high-impact solutions that lead to prosperous lives for all Oklahomans,” Snodgrass said. “The work-spaces are still in the process of being reconfigured – it’s an ongoing process that will be completed in early spring 2016. For now, we are crowded but happy thanks to the helping hands of our friends and partners who made the impossible possible.”

A unique and artistic use of what would otherwise be dead space, the conference room ceiling became an unusual canvas for a mural.

P750 Helicopter Maintenance Hangar

Frankfurt Short Bruza Associates was an Outstanding Award Winner for the P750 Helicopter Maintenance Hangar project in the 2014 NCSEA Annual Excellence in Structural Engineering awards program (Category – New Buildings $30M to $100M).

The Helicopter Maintenance Hangar was constructed at Naval Air Station North Island, the birthplace of naval aviation. Architects and structural engineers collaborated on a facility design worthy of this location, worked to control its visual scale and soften its industrial nature.

structuralmagazine_p750-hangar_05-15Land-side points of entry utilized cast-in-place concrete structures in naval aviation themed elements to create organizational, material and spatial hierarchy. Set behind these elements, the massing of the two-story administrative portion of this facility undulated to create a softer rhythm across its 631-foot front face and created opportunities for operable windows, daylight and outdoor break areas. A curved roof profile sculpted the hangar bay’s boxy volume and provided a visual transition from the lower administrative space behind. A second curved roof feature was added over each squadron’s space and was rolled up over the hangar roof to resemble stacked waves, which further broke up the massive volume. Translucent insulated panels in the vertical zone of the trusses provide significant natural daylighting, and at night give the appearance the roof is much thinner and is hovering over the lower walls. Vertical lifting hangar doors provided a clean appearance, and columns were minimized to maintain the effect of one continuous opening across the front of the facility.

Although the elevated design aesthetic immediately catches one’s eye, the structural challenges and solutions were a major component to this project’s success. Not only did the structure have to support and compliment the architectural features, it had to meet several environmental and physical demands such as a corrosive marine environment, high seismic considerations and a site which was determined to be liquefiable.

Historically, the project site was below sea level and had been reclaimed by placing fill soils to get above tide levels. A layer of liquefiable soils was identified and a Site Class of ‘F’ was assigned. Forty foot deep stone columns were constructed across the site to reinforce and densify granular soils. This provided an increase in bearing capacity, decrease in settlement and mitigation of the potential for liquefaction. After the construction of nearly one-thousand stone columns, this deep densification soil improvement program improved the Site Class to ‘D’.

Structural engineers utilized buckling restrained brace technology to reduce the design seismic loads imposed on the structure, provide superior ductile and energy dissipative behavior and simplify the entire structure in general. Due to a higher behavior factor and increased fundamental period, smaller structural members could be utilized, connections were simpler and the required seismic bracing demands were reduced on all building systems. As an added benefit, fewer expansion joints were required, thus further simplifying the structure and freeing up more functional space for the facility’s occupants.

While the aforementioned technologies were highly effective solutions, the ingenuity in the design of the hangar trusses had the largest overall impact to aesthetics, building function and economy. The top chords of the truss were segmented, and purlin end connections had individual vertical adjustment to create the varying roof curves. Truss symmetry was utilized throughout, with special consideration given to the location of vertical members to control shadows visible through the translucent insulated panels. The truss bottom chords supported bridge cranes, fall arrest systems and extensive catwalks. These catwalks and platforms permitted building HVAC equipment to move into the hangar space in order to free up additional floor space for each Squadron.

structuralmagazine_p750-hangar_05-15-2The 112,000 square foot helicopter maintenance facility measures 631 feet wide by 151 feet deep and is over 65 feet tall. It utilized 1,487 tons of structural steel including connections, 5359 cubic yards of concrete and achieved LEED® Gold certification. Most importantly, this new facility improves day-to-day readiness and mission execution through its arrangement and state-of-the-art features, but the Navy also proudly stated the facility would, “… inspire and enhance Sailors’ morale, both on-board (the Air Station) as well as those across the bay.”

Construction Administration Makes a Difference

Once FSB’s architects and engineers finalize their designs on a project, our construction administrators’ work is just beginning. They are the voice of FSB’s architects and engineers once drawings are handed over to the construction team to translate them from the page into the real world.

You can put a window in many different ways, and clients want someone there who can have some judgment on whether the work performed meets the intent of the design. Our construction administrators (CAs) keep the contractor from taking shortcuts or overlooking steps to make certain the owner gets the quality product they are paying for.

Not every project needs enhanced construction administration. The more complex a project is, the more clients benefit from the presence of an experienced CA on the job. With backgrounds in either architecture or engineering, Our CAs solve a lot of problems in the field and know when and who to involve when something doesn’t look right.

Buildings are getting smarter and smarter, and that makes the construction process more complex.

Construction administration is a service some owners choose to add on to their design projects, and the firm works with its clients to figure out the right level of involvement an administrator should have on the project, depending upon the complexity and nature of the building. The mistakes our CAs may prevent can save owners millions by pre-empting the need for expensive do-overs.

For example, our CA noticed a worker on one worksite cutting windows to be fitted into place on the side of the building. The windows had been prefabricated and sealed in a factory, but because the wall had been constructed slightly off, the windows weren’t fitting. Had our CA not been onsite, the compromised windows would have been installed with vapor soon seeping between the sheets of glass and creating a film inside the windows. No one would have known what had happened and the owner would have had to spend their money to then replace the windows after the fact. This catch saved the owner a six-figure cost.

When you are working on a $40 or $50 million project, one mistake on the worksite can cost in excess of a million dollars. Construction administration is sound insurance for the client.

Not only are construction administrators the voice of the architects and engineers on the work site, they’re also another set of eyes and ears for the client. Where many large companies once employed experts on their building maintenance staffs that would understand and oversee construction projects, they’ve scaled back. Many clients now rely more heavily upon construction administrators to advocate for the agreed-upon design. Construction administrators provide regular analysis to FSB clients about the progress of their projects and flags any concerns they might have from reviewing monthly pay applications, construction schedules and walking the site.

Q & A on being an Owner’s Representative

Going to bat for our clients…

The role of owner’s representative is its own separate niche, in many ways independent of standard architecture and engineering services, and it’s one that’s extremely important. When we fulfill these duties for a client, they are placing an enormous amount of trust in our team, and we take that trust very seriously. Here in this brief Q and A, FSB Principal Fred Schmidt outlines what these professionals do and the unique ways in which they help our clients.

Q. Tell me about the owner’s representative role and what duties it comprises.
A. Essentially, when you take on the owner’s representative role you’ve become part of that owner’s in-house team. You become the adviser, and with that comes a long list of responsibilities. The number one reason we’re there is to provide quality assurance and to make sure the client is getting everything they’ve contracted for from both the design and construction teams. As the owner’s rep we are basically interpreters of what the contractor is doing. We provide quality oversight, and we help the owner forecast what’s coming up, especially if we anticipate any problems. We outline the pros and cons, giving the owner the information they need to make crucial decisions. By doing this, we can successfully keep most projects on schedule and within budget by avoiding expensive change orders, construction delays or conflicts between the contractor and the client.

Q. What specific tasks are involved in providing this quality control?
A. There is a lengthy list of services that the owner’s rep performs, which can vary from project to project. Some examples of these duties are: regular on-site inspection of the construction site; assistance with developing a master plan; facilitating meetings between the contractor, architect and client; ensuring compliance with all federal, state and local requirements; acquiring any needed permits; ensuring the contractor provides appropriate documentation and record-keeping; reviewing plans and specifications for their suitability to the project goals; assisting with acquiring and reviewing funding sources; reviewing contracts and handling change orders.

Q. When do companies typically need an owner’s representative?
A. The level to which owners may choose to engage depends upon two factors. The first is their ability to oversee professional services themselves, since many companies don’t have anyone in house with the necessary skill set. Others who have experience with many projects, such as higher education institutions, typically don’t need to hire someone, as they have staff who can handle what’s needed. There are exceptions to this, though. Sometimes government agencies or larger companies have so many projects going on at the same time that they need outside help to take care of them all, which is when they come to us.

Q. How has the role of owner’s representative changed in recent years?
A. The role has evolved over the last several decades, but again is primarily focused around quality assurance. This is also a growing service niche. The real change is that while traditionally this role has been filled by an architect, other professionals like project managers and construction administrators are increasingly assuming those tasks. However, it’s still more of a natural fit for architects because of our standard role in overseeing the entire design/construction process.

FSB seismic design specialists in Oklahoma apply world-class expertise locally

Although earthquakes in Oklahoma have historically been low on the list of threatening natural disasters, the state has experienced a major increase in seismic activity in recent years. This increase has caused many residents to begin questioning the effects of earthquakes on the state’s infrastructure, and led many property owners to scrutinize their buildings’ preparedness to survive a major seismic event.

“In Oklahoma, designers are used to building for tornadoes but less used to building for earthquakes,” FSB Director of Structural Engineering Ben Wallace said. Wallace earned his PhD at Stanford, where he was part of a joint United States-Japan research cooperative looking at seismic resistance in structures. “In a tornado, a building has to resist strong wind pressures and impact from debris. Earthquakes are very different — the building has to be able to move around and not collapse. Seismic forces are much less predictable than wind pressures. The ground just shakes as hard as it’s going to shake and the building has to ride that out.”

Wallace, along with colleague Tom Bush whose PhD dissertation work at the University of Texas centered around the seismic strengthening of buildings, have applied their knowledge to FSB’s projects in many parts of the world, including historically earthquake-prone regions. Most recently, for example, the pair was part of an FSB team designing three Navy aircraft hangars in the San Diego area, an area with historically high levels of seismic activity.

Locally, FSB’s seismic design knowledge was recently applied to the design of the Edmond Public Safety Center, completed in October 2015. Because of its emergency management function and jail holding cells, the center represents a category of buildings that must remain operational following an earthquake.

The two structural engineers represent an uncommon concentration of expertise for a design and engineering firm in their home state, and with the increase in seismic activity in Oklahoma, local demand for their specialty is increasing.

“Everyone wants to know ‘Can my building take a magnitude 5 earthquake? A 6?’” Wallace said. “There are many factors people don’t see that go into helping the seismic performance of a building. In fact that’s one of the goals is to make sure people don’t see them. They are hidden but they are very important.”

Two of the most important factors are the materials used and the way these materials are connected, according to Wallace and Bush. In general, unreinforced masonry buildings, common in older commercial construction, are most susceptible to earthquakes. Steel or concrete frames are stronger. From examining the building plans of existing structures, the engineers can express an opinion on how fortified a building would likely be against a significant earthquake. The best time to structurally reinforce a building for earthquakes is during its initial construction, and the second-best time is during a major renovation.

Importantly, a lot of earthquake damage is not structural, but caused by large equipment like furnaces and water heaters tipping over, Bush said. For example, a water heater might tip, break a gas line and cause the building to catch fire, or a pipe could fall from the ceiling and hurt someone or cause damage. To protect a building and its occupants, mechanical and electrical engineers reinforce plumbing and heavy equipment using seismic bracing.

“Seismic design is total design,” Bush said. “It crosses disciplines and needs to be consistent from architectural work through to structural and electrical engineering. It’s all of us.”

At a multi-discipline firm such as FSB, architects integrate input from structural and mechanical engineers as they design rather than seeking an engineer’s sign-off after the fact. The collaborative process results in a more integrated, cost-effective final plan. FSB’s structural engineering department is involved in every architectural plan.

Building codes do require a certain level of seismic reinforcement on every job, no matter the region. These standards have only increased over the years as awareness of seismic activity grows.

“The big one hasn’t hit Oklahoma,” Bush said. “The day the San Francisco earthquake comes here will be a new day. I imagine we would see stricter codes and receive more attention from local clients, as we see constantly with tornado reinforcements. No matter what, we are committed to continue bringing the same expertise we apply on projects in California and Alaska to every project.”
