CAA 2016 WinnerRoger L. Johnson

1n 2016 the North Dakota Ready Mix and Concrete Products association celebrated their 50th Anniversary. At the Associa-tion’s 50th Annual Convention in January Roger L. Johnson was presented with the prestigious Career Achievement Award (CAA). The CAA is essentially the concrete industry of North Dakota’s Hall of Fame. It is presented to those individuals who have made significant contributions to the concrete industry of North Dakota, to the North Dakota Ready Mix and Con-crete Products Association and to the community in which they live. The award is not presented annually, but rather only when the NDRM&CPA Board of Directors feels there is someone worthy and deserving of this recognition. In its 50 year history, the Association has only presented the Career Achievement Award eight times previously, with Roger John-son becoming the 9th member of this select group.

Recipients of this Award must have been an Active Producer or Active Product member of the NDRM&CPA in good standing for at least 10 years and must have made sig-nificant contributions of time and effort to the Association. In addition, they must have made significant con-tributions to the concrete industry of North Dakota through marketing, promotion, education, innovation, etc., contributions that served to benefit and further the industry. And finally, recipients must be of good integrity and responsibility and must have made positive contributions to the community in which they live.

Roger Johnson clearly meets and exceeds all those criteria. Roger was in the concrete industry for 45 years, 33 of those years with Lehigh Cement. He began his career with Lehigh in 1971 as an Assistant Terminal Manager in Cedar Rapids, IA. In 1973 Roger was promoted to Assistant Terminal Manager at Lehigh’s Burnsville, MN facil-ity. From 1973-1982 Roger served as either an Assistant Terminal Manager or Terminal Manager in Burnsville, MN, Fargo, ND and Beloit, IL. In 1982 Roger joined St. Mary’s Cement in Milwaukee, WI as their Assistant Grinding Plant Su-perintendent and in 1984 he returned to the Fargo-Moorhead area with Northwestern States Portland Cement Co. as their Terminal Manager and Sales Rep. In 1990 Northwestern States Portland Cement was sold to Holnam. Roger retained his position with Holnam until 1992 when he rejoined Lehigh Cement and from 1992 until his retirement in 2016 Roger served as Lehigh’s Senior Territory Manager covering eastern North Dakota and Minnesota. Beginning in 1986, Roger was an active member of the North Da-kota Ready Mix and Concrete Products Association for 30 years, serving on the NDRM&CPA Board of Directors for 10 years. He has served as Chairman of the NDRM&CPA Promotion Commit-tee; he has served as liaison with the North Central PCA and chaired their ICF Above-Grade Promotion Com-

mittee; for many years Roger served as MC for the NDRM&CPA Annual Awards Banquet; he has represented the NDRM&CPA at numerous North Central PCA Regional Promotion meetings, as well as representing the Association at the National Association of Builders Convention as a volunteer in the Concrete Pavilion; he has served on the North Dakota Concrete Council Board of Directors. For 30 years Roger was a tireless worker and an effective promoter for the Association.

Other professional organizations Roger has been involved with include the Fargo-Moorhead Builders and Trad-ers Exchange where Roger twice served as President; he was the Promotion Chairman for PCA Concrete Alli-ances Promotion Plus Forums; he has served on the board of Directors for both the Aggregate and Ready Mix Association of Minnesota (ARM) and the Minnesota Concrete Masonry Association; he has served on several Boards of Education for the schools his children attended; he has served as President of the Parish Council and Trustee for St. Joseph Catholic Church in Moorhead; and has served as Treasurer for both the Lake Ida Town-home Association and the Alexandria, MN Knights of Columbus.

Roger and his wife Suzanne live in Alexandria, MN and have two children and three grandchildren.

Perhaps 2006 CAA recipient Martin Warborg said it best when he said, “Roger has worked his butt off for the concrete industry and for the North Dakota Ready Mix & Concrete Products Association. It’s about time he was recognized with the Career Achievement Award.”Previous CAA winners were:1988 - Ken Shaffer, Atlas, Inc.1989 - Jack Olin, Dickinson Ready Mix Co.1990 – Jerome Dunlevy, Concrete, Inc.1991 - Jake Ochsner, F-M Ready Mix, Inc.2000 - Bob Beyer, Beyer’s Cement, Inc.2003 – LaVerne Stippich, Stippich, Inc.2006 - Martin Warborg, Lafarge Dakota, Inc.2008 - Terry Bladholm, Concrete Sectional Culvert, Co. 2016 - Roger Johnson, Lehigh Cement

With the slow deterioration of a portion of the pavement near the UND hanger at the Grand Forks Airport, it was finally determined that a replacement project should be undertaken. Funding was secured and contracts were let for the replace-ment work.

The project included ramp replacement of East Apron B, North Washbay Apron, South Apron C, and the Helo Pad. Additionally, North Apron C remained in place and had minor maintenance work in form of spall repairs and joint resealing.

Layout of the project showed that a majority of the recon-struction project could be placed with a slip-form paver. The fine grading of the base matrerial was done with a trimmer. The concrete was placed at a 25 foot width. And texture and

cure was applied with a full width curing machine that was run off the same stringline as used by the paver. Dowels and tie-bars on the con-struction joints were installed by drilling with a two gang rock drill and epoxying the bars with a 1:1 epoxy machine in the drilled sockets.

A majority of this project was 6” in thickness. With this thinner pave-ment, the engineer requested that loaded trucks delay use of the new pavement as long as possible. This challenge was overcome by using a telebelt to place the smaller irregular sections of concrete.

Concrete mix was limited to a maximum of 2” slump per P-501 FAA specification. Fly ash was a critical mix component to meeting the Al-kali Silica Reaction (ASR) spec limitations required by FAA. The fly ash also decreased permiability while increasing workability. Ultimately, the flyash replacement also increases durability for a long service life. As the project proceded, strength gain of the concrete was very consistent, al-lowing early drilling for tie-bars and following in-fills of new pavement. The project involved 38,500 S.Y. of 6 to 9 inch pavement reconstruction.

Fluffy Fields vineyard & Winery Owner: Kevin & Deb Kinzel Building Design: Bosch Lumber Engineer: CWStructural Concrete Contractor: Winn Construction Supplier: Dickinson Ready Mix

DecorativeCategory

Design for Fluffy Fields Vineyard & Winery started in the spring of 2014, after the wine making hobby of Kevin and Deb Kinzel grew to the point that they needed a space devoted to their hobby. Kevin and Deb saw an opportunity to be a part of the southwest North Dakota regional tourism experience by providing visitors to the area with the chance to experience our region through the unique wines made from grapes and other fruits grown right here in southwest North Dakota. A major step in that direction was the construction of the 95’ x 60’ winery building with a classic prairie architectural design.

In 2015 they broke ground on the building that would be the new home for their venture. Fluffy Fields consists of a 3,000 S.F. lower level and a 5,700 S. F. main level. In keeping with their theme, the complex includes a one acre grape vineyard, one acre of gardens, and a one acre

orchard. The basement contains a bottling room, two separate wine cellars and a private tasting room. All floors received a high level polish before application of stains. The lower level was colored using Burnt Sugar acid stain. The main level contains the main tasting room, an events room, kitchen, office, bathrooms, the fermentation room, and the crushing pad. A 75% Black Diamond acid stain was used on the floors in the tasting room, events room, and the fermentation room. The women’s bath-room used a Deep Purple acid stain, while the men’s bathroom used a Kelly Green acid stain. The hallways were all done using a New Mexico Blue acid stain.

But the numerous acid stain colors aren’t the only decorative concrete features in Fluffy Fields. The main hallway features a water-fall constructed from chicken wire and a pea-gravel concrete mix. The Stream on the waterfall was stained using the same New Mexico Blue that is on the floor, and the natural looking rock (concrete) contained in the water fall were stained the Burnt Sugar color. The exterior and the wall of the water fall was constructed using a River Rock stone (concrete). As part of the waterfall, a floor mantle was cast using an integral Leather color and antique charcoal release and imprinted with a grape pattern. Imprints were hand painted using an acetone based Riviera and a Cactus stain. The fireplace located in the tasting room

utilizes the same River Rock stone for its hearth and mantle. In the tasting room, the bar tops and the wine barrel table tops were cast us-ing a Split Rock border, a Leather integral color and Charcoal release.

The exterior walls of Fluffy Fields was done using a Prairie Ledgestone Bucks County stone which ties in with the exterior flat-work. This flatwork was done using two different integral colors, one release, and three different stamps. A majority of the flatwork was done using a Leather integral color, a charcoal antique release and a plank stamp pattern. Other areas feature a Doeskin integral color with a charcoal antique release and a slate stamp pattern. The outside bor-der has a grape stamp pattern with a charcoal antique release. In total there was approximately 700 cubic yard of 4,000 psi concrete used in this project.

Fluffy fields is currently in full swing with the capability of bottling up to 225 gallons of wine a day. The Kinzels have certainly made their dream hobby into reality to say the least. Now the only thing left to do is sit back…. Relax…. And have a glass of wine.

ND State Mill Expansion

Owner: State of North Dakota Engineer: Vansickle Associates Architect: Vansickle Associates Contractor: Vigen Construction Sub Contractor: Flatcrete Supplier: Strata Corporation

CommercialCategory

The North Dakota State Mill is a unique business model in the milling industry. The state owned operation has been very suc-cessful historically, and has provided finished flour products worldwide. The business is a key component of the ND agriculture economy.

This $35.5 million addition to the North Dakota State Mill has improved efficiency and capacity for the Mill. With the completion of this project the ND State Mill is now the single largest milling facility in the western hemisphere.

Andrew Vigen, Vigen Construction, reports that a worldwide sup-plier of slip form construction machinery, which Vigen Construc-tion works with, stated that “this project was the most complex and challenging slip form construction project for our company to date”.

The project required exact engineering for the finished structure, as well as for the complicated construction phase. Atten-tion to detail and organization was required in construction. Pressure relief panels, precast structural beams, weld plates, and reinforcement steel had to be inserted at the correct elevations and spacing during the slip form construction. There were 102 openings and 94 structural precast beams that were placed integrally as construction proceeded.

Approximately 6,500 cubic yards of concrete were placed in the structure. Nine different classes of concrete mix designs were incorporated into the total project. Time of set curves and strength gain curves were developed in the engineering phase, and were invaluable tools during the slip construction. Predicting the concrete engineering behavior was critical when inserting the precast structural beams, casting in place openings, and placing the other construction elements.

The mill portion of the structure is 109 feet tall, while the cleaning house portion is 180 feet tall, and the freight elevator of the stairwell is 129 feet tall. The slip form itself had to be cut and reassembled as these varied elevation were reached. Es-sentially creating two different slip form operations on the project once the 109 feet elevation was reached.

The existing structure surrounded the cleaning house portion of the slip construction on two sides, essentially acting as the outside forms for this portion until the elevation was exceeded as required for the new construction. At which point, additional form work was incorporated on these sides to finish elevation. Tracking beams were utilized to ensure that the new construction would stay plum along the old structure and through the transition formwork phase.

As a result of a great project team, including engineering, contracting, and material suppliers, this project was successfully constructed meeting or exceeding all project goals.

In 2014 when the design of the Crooked Crane Trail began, everyone involved wanted a long-lasting sustainable trail to enhance the recreational experience for area residents. What they got exceeded expectations. The Crooked Crane Trail isn’t just used by walkers and joggers, it is also used by people who enjoy biking, roller blades, fishing, Frisbee golf, outdoor enthusiasts, dog walkers, and others. This is why Crooked Crane Trail was such a necessity. As an added attraction, the City of Dickinson added exercise pods with stationary fitness equipment and playground areas along the trail so all ages can enjoy it.

The 1.8 mile double loop trail is the first phase of an 18 mile system that will continue around the northwest and southwest sides of Patterson Lake and connect back east with walking trails in Dickinson. The path was constructed utiliz-ing a slip form paver as well as a concrete pump depending on access conditions. The trail is nearly 10,000 lineal feet long, 10’ wide and 4” in depth. In addition there are nearly 550 lineal feet of 5’ sidewalk to tie the trail in with existing facilities. Almost 1,400 cubic yards of 4,000 psi concrete was used to complete this phase of the trail. The trail has two loops along

with a land bridge that spans a small creek. The trail also features numerous switch backs to flatten some steep grade areas of the trail to comply with ADA requirements.

The design of this project was done in a way that matched the existing topography of the area. The end result of this project is a wonderful, safe, and long-lasting trail that can be enjoyed by all, with beautiful natural views of Patter-son Lake and the surrounding areas.

St. Alexius Medical Center Owner: NexCore Group Engineer: HGA Architects & Engineers Architect: HGA Architects & Engineers Contractor: F.A. Wilhelm Construction Co, Inc. Precast Supplier: Wells Concrete

PrecastCategory

Headquartered in Bismarck, ND, St. Alexius Medical Center (SAMC) has a strong reputation in Minot, a city that is expe-riencing extraordinary population growth. Until recently, SAMC provided the Minot market with outpatient services in a converted one-story office building. The new two-story, state-of-the-arts 67,140 SF Minot Medical Plaza has replaced the one-story clinic with SAMC as the anchor tenant. This multi-purpose ambulatory center includes clinics for primary and specialty care, diagnostic imaging, lab, physical therapy, future ambulatory surgery, and complementary retail uses such as a pharmacy and optical shop.

Wells Concrete provided the precast concrete wall panels for this project. The two-story structure is designed with a steel structure and insulated architectural precast panels cladding.  The precast finish boasts a combination thin brick and acid etch exterior finish with cast-in electrical to further streamline construction.  Early on in the project’s development, the owner contemplated the use of precast and toured Wells Concrete’s Grand Forks plant with the design team for a better un-derstanding of precast.  After precast was selected as a solution for this project, the Wells Concrete team coordinated with the architect on precast layout efficiencies and finish options.

With a very aggressive schedule and a desire to occupy the new building by June 2015 precast was an ideal solution.  Wells Concrete began production in their Grand Forks’ facility in mid-September with installation set for mid-October 2014.

The Concrete Advantage: Precast concrete offers an efficient delivery model allowing building construction to proceed while the design is developed. The aesthetically versatile precast concrete can take nearly any shape or size, be manufactured in virtually any color and comes in a wide variety of finishes. With concrete, you are limited only by your imagination. Precast concrete products are manufactured off-site, under roof and are delivered ready to install when needed. This innovative process compresses project schedules, reduces safety concerns, reduces site disruption and reduces overall project costs by requiring fewer trades for construction and fewer people on site. Sustainable Design: Environmental - Precast concrete structures are completely recyclable, making their impact on the environment minimal. Precast concrete satisfies a growing demand for sustainable design and construction. Carbon footprint in both the construction and operation phase is minimized through ease in construction and efficient insulating capabilities.

Energy Efficient: Costs associated with heating and cooling can be greatly reduced through concrete’s thermal mass benefits. Reduced peak heating and cooling loads can be achieved because concrete reacts slowly to changes in outside temperature. In addition, edge-to-edge sandwich insulation panels eliminate thermal leakage through studs or webs in ordinary construction systems. And these systems provide significant advantages in reducing wind infiltration as measured by “blower-door tests”. Low Maintenance: Concrete panels provide a long service life due to their durable, low-maintenance surfaces. The exterior of a precast concrete structure can be left unpainted without damage from the elements. Precast concrete interiors are less subject to damage and easier to wash. Construction with concrete exterior and interior walls provides long-term durability inside and out, and precast concrete construction also provides the opportunity to move and reuse panels to refurbish the building, rather than tear it down, should its use or function change.Sound Control: Because of concrete’s density, concrete buildings absorb sound, making it an ideal choice for medical, commercial and residential buildings. Concrete walls provide a buffer between outdoor noise and the indoor environment.

Element Resistant: Concrete structures provide superior resistance to fires, natural disasters, insects, and mold. Like no other building mate-rial, its resistance to wind damage, fire, floods, earthquakes, termites, decay, mold and mildew provides lower maintenance and insurance costs. Vermin and insects cannot destroy concrete because it is inedible. Concrete is noncombustible and can contain a fire within boundaries. As a separation wall, concrete helps prevent fire from spreading throughout a building or jumping from building to building.

Sustainable Design: An inherent characteristic of precast concrete is its natural resistance to mold plus greatly reducing health concerns from VOCs and off gassing. With these environmentally friendly advantages, precast concrete satisfies a growing demand for sustainable design and construction. Precast is perfect for preserving resources and protecting the environment through sustainable building practices. Precast concrete buildings also correlate with at least four categories of LEED certifica-tion.

The two story structure included 104 insulated exterior pieces together with 12 interior wall panels.

In May 2013, the North Dakota Legislature approved funding for a new $123.76 million, 325,000-square-foot, four-story University of North Dakota School of Medicine and Health Sciences (SMHS) building.

The structure has a north-south oriented “Main Street” around which there are clustered various classrooms, small-group rooms, an auditorium, simulation center, and anatomy labs. The east wing is for faculty, staff and administrative offices, and the west wing houses much of the research enterprise. The new facility also provides—for the first time under one roof—a home for all of the School’s departments.

The choice of building material made good sense. Because of the strength and durability properties

that you get with concrete, you’re able to achieve a resilient structure. Concrete is fire resistant, it won’t rot, mold, rust, or deteriorate. Concrete construction is energy efficient, and virtually maintenance free, which means the resources invested now will provide dividends for years to come.

The project utilized a post-tensioning construction method for the reinforcement of the floors. The project schedule demanded high performance concrete for the post tensioned floors as well as the other structural elements, such as columns. This concrete targeted 3000 psi compressive strength in one day and 6000 psi compressive strength at 28 days. Concrete workability of a seven inch slump was also targeted for ease of placement and consolidation.

The challenge when creating early strength gain in high performance concrete is maintaining a workable mix that can be utilized through a range of ambient temperatures and placement techniques. One must control the rate of heat gain and slump loss, while maintaining a low water to cement ratio for achieving high strengths and reducing shrinkage.

To that end, time of set, heat gain signature, and strength gain curves were developed for the structural concrete mix designs. This allowed a basis of the expected workability window for any given ambient temperature and placement time for the concrete mixture. An admixture package consisting of the following could then be adjusted for the concrete performance and expected conditions at the time of placement:

High Range Water Reducer – Maintain a low w/c ratio while increasing slump for ease of placement, consolidation, and strength

Hydration Stabilizer – Control early Concrete temperature gain, ensuring a proper dormant period for placement and

crystalline structure growth for strength & durability

Slump Retention – Essentially a time released HRWR allowing for an extended workability window for slow placements and warm temperature conditions

Approximately 23,000 cubic yards of concrete went into the construction of this project.

This new building allows the School to fully implement its Healthcare Workforce Initiative, which is a four-pronged plan to help address North Dakota’s healthcare workforce needs now, and in the future by reducing disease burden, retaining more of the School’s graduates for practice in North Dakota, training more practitioners, and improving the efficiency of the state’s healthcare delivery system.

Joining the mainstream owners and developers choosing concrete pavement for parking surfaces, Memorial Square businesses have chosen well. But their customers will also benefit, especially when safety comes into play. The light colored surfaces will be appreciated during hot summer days. And the night reflectance under LED lights (or any lighting

system) will show clear superiority compared to as-phalt when bright ambience and visibility for pedes-trians are important.

This 6” pavement has been engineered to provide long life with minimal maintenance over its service life. The contractor chose low water/cement ratios combined with durability enhancement with 25% cement replacement with fly ash. Curing was timely and jointing lengths appropriate.

Compliments to the Owners at Memorial Square for a great investment and superior aesthetics while providing the ultimate in safety for their customers.

Concrete Paving - 10” Non-reinforced - 27,000 SY6” Decorative Colored Concrete Median, Reinforced - 2,800 SY 5” Shared Use Path, Reinforced - 9,000 SY

The project consisted of reconstruction of approximately one mile of 32nd Avenue West from Sheyenne Street to the Horace Diversion. The existing two-lane rural roadway section was replaced with an urbanized 4-lane concrete street with turn lane channelization, multi-use paths. The project also included a decorative concrete median and concrete multi-use path.

The purpose of the project was to improve the safety and traffic operations of the arterial corridor in the City of West Fargo south of I-94, where rapid growth has stressed the city’s infrastructure. The project was necessary to accommodate future growth planned for the corridor and allow for safe mobility from Sheyenne Street to the Horace Diversion and to the two schools located within the corridor. A major design element was to pro-vide capacity for the future volumes of traffic that are expected on the road-ways. Two through lanes are provided in each direction on 32nd Avenue, along with left and right turn lanes at intersection locations throughout the corridor.

Concrete pavement was chosen for the roadway because of the length of its service life and the expectation of large loads as the area develops. Concrete provides a great visual contrast from the adjacent landscaped areas and decorative lighting.

In addition to concrete pavement in the roadway, a concrete Shared-Use Path was installed adjacent the roadway to accommodate pedestrian and non-vehicular traffic. Concrete was chosen for shared-use paths to provide visual contrast to the surround-ing landscape, long term surface quality, and load capacity to support snow removal equipment. Decorative colored concrete was used in medians and boulevards in areas too narrow to support vegetation and where deicing materials would have detrimental effects on vegetation. The decorative colored concrete produces a surface that adds to the aesthetic quality of the project as well as providing a durable, low maintenance surface in narrow median and boulevard areas

State Avenue Railroad Bridge

Owner: City of Dickinson & NDDOT Engineer: HDR Engineering Contractor: Ames Construction Concrete Contractor: Winn Construction Supplier: Dickinson Ready Mix

BridgeCategory

The project features a bridge over BNSF railroad tracks on State Avenue, the N-S designated truck route for Hwy. 22 in Dickinson. Other construction included replacing un-derground utilities, and construction of concrete pavement, MSE retaining walls, traffic signals, lighting, sidewalk, and decorative boulevards. The total cost of this project was ap-proximately 33 million dollars. The construction began in the summer of 2015 and was completed in October of 2016. Ini-tial construction involved rebuilding the 30 year old concrete pavement in the project vicinity. In total, almost 6,400 cubic yards of ready mixed concrete was used in paving this project and approximately 13,700 lineal feet of curb was constructed.

Built alongside most of the concrete pavement is a colored and imprinted concrete boulevard. The boulevard used an integral Marigold color, and imprinted with a Dublin Cobble stamp pattern. There was also more than 67,000 square feet of 4” concrete sidewalk and driveways in this project. The boulevard, sidewalk, and driveways utilized more than 1,100 cubic yards of concrete.

To establish grade for the bridge, the contractor installed 95,000 tons of select granular fill. Fill soil was contained within a Mechanically Stabilized Earth (MSE) retaining wall system covering 38,000 S. F. of vertical surface.

The bridge columns used form liners to achieve an Ashlar Stone surface texture to match the wall pattern. A two coat Desert Sand colored stain system maintained color consistency throughout.

The bridge deck utilized nearly 4,000 lineal feet of 45” pre-stressed I-beam bridge girders spanning a total of over 350 feet. Approximately 1,500 cubic yards of AAE-3 ready mixed concrete was used in the construction of the bridge deck. The bridge deck was poured using two concrete pumps and a bridge deck paver. The entire bridge deck took only 12 hours to pour and was done at night to minimize traffic interruptions. Total concrete used on this project exceeded 12,000 cubic yards.

This bridge has been needed in the City of Dickinson for years as the first discussions for a project of this type were held in the early 1980’s. The final product is an aesthetically appealing bridge, new safer roadways with bright sidewalks with clean and good looking boulevards throughout. The State Avenue Bridge will also give first responders and citizens a clear route to the south side of Dickinson without the fear of being held up by a train. The bridge will serve Dickinson’s transporta-tion needs for many, many years to come.

SiteCast/Tilt-up

Category

This project consists of office and warehouse space for their beverage distribution network. The project goals targeted maximum energy efficiency while producing a durable and appeal-ing interior and exterior. While no design certification was investigated, many of the components of LEED were followed to achieve the environmen-tally friendly and low carbon footprint construction. Along with increased energy efficiencies with lower heating and cooling costs, the concrete con-struction provides significant reduc-tions in insurance costs through high fire resistance and low combustion opportunity. These, in addition to the concrete parking lot, contributes to a

total package of low maintenance and long life building components as desired for a “Sustainable Design” type project.

Early on in the project’s development, the owner contemplated the use of concrete and various structural options for their new facility. Without compromise in any area of quality, the Thermomass Building System was chosen for the wall panels. Wall panels had 8 inch thick base layer followed with 3 inch insulation and a 3 inch concrete wythe. Layers were connected with composite glass fiber connectors. Roof specs required a minimum of R-30 and walls were able to provide a true R-21 without thermal leakage at studs, etc. The exposed concrete interior also assists with energy efficiency by the thermal mass capture/release of heat when doors open in hot or cold weather.

KBW constructed the Site Cast/Tilt-up wall panels through forming and casting them on the main floor slab, eliminat-ing cost in comparison to alternate systems. The southeast corner of the structure has a mezzanine for additional office space and is supported by the structural panels. The as-cast exterior is coated with a Tex-Cote XL-70 applied finish. Part of the interior wall exposed concrete was coated with Promax 200 Latex paint with the remainder uncoated.

Together with the total concrete parking and loading dock facility, a decorative patio is provided in the SW corner of the facility. The slate grey colored concrete provides a decorative element for employees who wish to explore the outdoors dur-ing breaks and lunch-time.

Mass Concrete Remote Thermal MonitoringBismarck Water Treatment Plant

Owner: City of Bismarck Contractor: PKG Contracting Inc. Engineer: AE2S Technology Support: HM Technologies - ConXedge® Supplier: Strata Corporation

InnovationCategory

Projects involving mass concrete have a need to limit maximum temperature to 150oF and differential tempera-tures from center to exterior to 35oF. For the Bismarck Wa-ter Treatment Plant project, the mass concrete was placed during times of cold weather conditions. Initial thermal analysis indicated that the cold weather effects to tempera-ture at the surface of the concrete was the critical challenge in reference to differential temperatures. Contrary to tra-ditional engineering when considering mass concrete, the tradition is to cool center mass. Here it was to adjust heat at the surface through selected R-value of insulation in or-der to minimize cost and simplify construction. Thermal prediction models considering predicted thermal output of the mix combined with form insulation were used to pro-vided theoretical starting points. To address the innovative

approach for thermal control, the system allowed insulation models to be easily changed based on the changing environ-mental conditions at the time of placement and thereafter.

Thus, it was critical that a “real time” thermal monitoring system would be required so changing thermal conditions could be addressed. The project stakeholders turned to HM Technologies of Castle Hill Australia for help. This project became a “beta test project” for their new ConXedge concrete thermal performance monitoring system. ConXedge is a Cloud based thermal management solution incorporating innovative thermal measurement and com-munication hardware which enable real time monitoring in concrete applications. ConXedge collects in-place thermal data accurately and cost effectively from almost anywhere in real time. Individual projects and placements can be config-ured to provide auto-notification and warning parameters. The system allows all concrete project stakeholders access to the concrete thermal data using concrete maturity (Arrhenius or Nurse-Saul) or mass concrete technology.

The system was installed in the project’s mass con-crete and worked superbly. Status emails and texts were generated as advertised, and in one instance alerting the need to increase the insulation due to colder ambi-ent temperatures than predicted. The web portal was accessible to all stakeholders providing real time thermal conditions, as well as recording historical data for the project.

Through the use of innovative technologies as used here in real-time thermal monitoring, all stake-holders can be assured of accurate monitoring leading to the highest quality and lowest cost for any mass concrete application.

Living the Message - Telling the StoryAs the ready mix concrete industry takes a breather, with the slump in oil activity, we have an opportunity to reprioritize our marketing focus in advance of the next frantic business cycle.

PrioritiesA first priority should involve our evaluation and refocusing on missed opportunities. Second, we need to establish a platform to maintain our existing advances, especially in the growth of the use of concrete for pavements. These two focus opportunities have been identified by our Board of Directors and its members are excited to find solutions at this critical time.

Lost OpportunitiesNationwide, our ready mix industry is alarmed at the decline in the standard of using concrete for multi-story buildings. The wood industry, through its check-off program, has been able to advocate changes in codes to move from 2 story to 4 story total wood building construction. This has essentially eliminated 90 percent of concrete building construction opportunities here in North Dakota, all during the greatest housing and commercial building spurt in our history. Alarmingly, as we drive down our recently developed urban zones, we see building after building that were built with 2,000 to 10,000 fewer cubic yards of concrete, as compared with the old code. The impact has affected almost all our major communities as our citizenry moves toward multi-family dwellings in lieu of single family homes. But does wood seem to be the ultimate solution? It seems readily apparent that a majority of our citizens would prefer to live in safe, quiet, solid, and environmentally friendly options built with components such as concrete, not wood. The NRMCA has identified numerous advantages of avoiding multi-story wood structures including fire susceptibility, safety for fire-fighters, structural deficiencies of wood construction, excess insurance premiums, mold susceptibility and other important considerations. We think that, given the scientific and common sense opportunity to identify the compromises made under the new codes, we can affect change. We expect that our building officials, fire fighters, city leaders and especially the building occupants will realize the flaws in their housing and commercial structures. Through a properly framed presentation on these compromises, we think our community leaders and citizenry will demand a return to the use of sound building construction options.

The PlanSo how will be accomplish this? We will partner with the NRMCA through a comprehensive media campaign, utilizing television and radio. Much of the investment has already been made through NRMCA media experts in preparation of the message. So with the help of local experts in advertising, we can execute our plan with little development cost. It is an opportunity to communicate the benefit of our great product in this and our other markets. We will start with the “Build with Strength” motto. We hope you will visit the NRMCA website at www.nrmca.com, to learn more.

We have solutions! So we are inviting you to join our members in an exciting comprehensive media and promotion campaign to recover the lost use of concrete in commercial structures and housing. This, combined with the preservation of our existing markets in pavements, will serve our members and enhance our product image. Through a partnership in this special effort, we hope to bring your business additional sales along with increased profitability for the long run.
