Sedona, Arizona

In 2017, the Barbara Antonsen Memorial Park received the Award of Merit under ENR 2017’s Best Project category.

Loven Contracting served as the CMAR Contractor on the new Barbara Antonsen Memorial Park in Sedona, Arizona. The park features new performance facilities, office spaces, public restrooms, landscaped lawn, a shaded seating area, and a steel canopy for the new stage. To maintain project budget, our team utilized step-by-step value optimization and value engineering processes while working closely with the City of Sedona.

Our construction services included extensive rock excavation, and installation of park improvements. The native rock at the site of the new park required hard excavation to create the foundation and utility trenching. To maintain project schedule, Loven Contracting performed careful planning and scheduling daily. In addition, to maintain the design aesthetic of the steel canopy above the main stage, our team carefully reviewed and adhered to the drawing during fabrication to guarantee the highest quality outcome. The new features enable the park to host a wide variety of activities for tourists and locals in Northern Arizona to enjoy.

Grand Canyon Visitor Center

Loven Contracting remodeled the Grand Canyon National Park Visitor Center and constructed a new 3,100SF, 248-seat theater addition. Scope of work included integration of new sustainability features, new exhibits, the installation of a terrazzo “river,” and multiple educational features. The Visitor Center’s new design elements and educational features are now favorite attractions at the highly visited site.

Millions of people per year visit Arizona’s Grand Canyon National Park. The vast majority of these tourists include the Visitor Center in their itineraries. The Loven Contracting team worked closely with the National Park Service to schedule construction work and implement safety plans that preserved the quality of experience for visitors, staff, and wildlife. This included daily safety inspections, screened fencing, and scheduling construction relative to bus tours to minimize activities during high visitor periods.

Construction was completed on an accelerated winter schedule. To mitigate the challenges of winter construction, a full scaffolding system was erected for the masonry phase of building construction and then left in place to provide a temporary weather enclosure.

Glen Canyon Bridge Pipeline Repair

Glen Canyon Bridge Pipeline Repair

Location

Coconino County, AZ

Glen Canyon National Recreation Area has their largest wastewater treatment facility located at Wahweap Marina, which pumps sewage to Page crossing the Glen Canyon Bridge at the Colorado River. The sewer force main at this facility hangs off the side of the bridge 800 feet above the water below and was deemed in critical condition. Loven Contracting acted quickly and performed immediate assessments of the pipeline structure upon contract award. 

After the pipeline breaches were identified, Loven Contracting developed a scope of work to perform the immediate repairs required to allow the pipeline to function properly. In order to access the pipe and begin the repair process, a bridge truck was utilized to lift personnel out and over the side of the bridge. Using the bridge truck required closure of a travel lane on the bridge, restricting traffic flow. Due to an outstanding traffic permit between ADOT and the local houseboat transportation company, the bridge lanes could not be restricted between the hours of 6am and 8pm. As such, all traffic closures and bridge truck activities were conducted after 8pm. 

In addition to our construction services, Loven Contracting provided valuable recommendations and advisement to the National Park Service to ensure the pipeline’s future long-term performance. This project came in below original estimates, providing an overall cost savings to the National Park Service.

Grand Canyon National Park, AZ

This project earned 19 out of 19 LEED points in the LEED Optimized Energy Performance category and was recognized for its exemplary regional design response to local Arizona conditions. This project also earned a Sustainable Building Award from Coconino County. 

The Science and Resource Management Building at Grand Canyon National Park, AZ is an award-winning Design-Build, USGBC LEED-Platinum certified, and federally-funded project. This project was built in collaboration with Flagstaff-based Civil Design & Engineering (CDE).

CDE and Loven Contracting worked together to design the two-story, 8,900SF building with a focus on sustainability and incorporating the surrounding park’s architectural styles. Our construction services on the Science and Resource Building included office spaces, conference rooms, laboratories, a gray water collection system, a rainwater collection system, solar panels, and LED lighting throughout. The end-product is an environmentally-friendly facility that blends into the landscape of the Grand Canyon National Park.

Flagstaff, Arizona

Loven Contracting worked with Highlands Fire District on the Design+Build delivery of a 4,000SF Fire Administration Building addition to the existing Fire Station and a 2,400SF Pre-Engineered Metal Building for the Bear Jaw Wildfire Hand Crew.

Construction took place during a heavy monsoon season, requiring 8-foot over-excavation, fill, and compaction to prepare the site. During construction, our team identified a leak in the fire loop as well as drainage challenges that were causing failure of the surrounding pavement. Loven Contracting mitigated these issues via a 3’ over-excavation and substrate rebuild to support heavy vehicle traffic. By completing this concurrently with the original scope of work, this enabled our client to achieve meaningful savings and we completed the project on-schedule.

William Lowell Putnam Collection Center and Library

Location

Flagstaff, Arizona

The William Lowell Putnam Collection Center and Library located in Flagstaff, Arizona is a new addition to Lowell Observatory’s educational facilities. The Putnam Collection Center and Library serves as a resource center for historian studies and includes a research library, processing room, staff offices, and a collections repository that houses historic photographs, photographic glass plates, an array of antique instruments, artifacts, and an archive of historic papers from across Northern Arizona.

Construction on the library was conducted through both the summer monsoon season and winter months in an environmentally sensitive area surrounded by a dense forest, slopes, and substantial amounts of basalt bedrock. Despite these environmental challenges, the Loven Contracting team delivered construction services on time and without disrupting Lowell’s active observatory campus. 

With the Steele Visitor Center, Hendricks Center for Planetary Studies, metal and fabrication shop, and smaller historic observatories located directly adjacent to the new facility, construction was scheduled so that all nearby facilities remained in full operation throughout the duration of the project. Because necessary rock blasting took place adjacent to historic telescope enclosures, buildings, and sensitive equipment, seismic monitors were utilized to verify resulting vibration activity. Blasting was precisely scheduled to avoid disruption to Observatory visitors and surrounding public areas.

Other aspects of the construction job on the collection center and library included:

  • A hydronic in-floor heating system was integrated into the temperature and humidity controlled archival center.
  • Motorized solar tubes that control lighting and UV in sensitive areas were installed.
  • A special walk-in freezer utilized to kill bacteria and insects at temperatures of -20° prior to archiving materials was installed.
  • Loven Contracting designed a glycol snowmelt system under a loading dock area with permeable pavers. This system required installation over 2” of rigid foam insulation, yet still had to have the compressive strength to support delivery trucks and general traffic.
