University of La Verne – West Campus Athletics Facility

Oltmans Construction Co. provided construction services and self-performed portions of the concrete work on the University of La Verne’s West Campus Athletics Facility project, the new home of the Leopards baseball and softball teams. The project required major coordination with the City of La Verne and the ULV Project Consultant Team in order to meet all state and local regulatory requirements and critical deadlines for school openings.

The existing offsite West Campus Area, west of Wheeler Avenue and South of Arrow Highway, covers approximately 16 acres and was undeveloped at the start of construction. The scope of work was to convert the existing West Campus Site into the new West Campus Athletic Facility, which involved mass grading, excavation, prepping and infrastructure work including all dry and wet utilities as well as the extension of Wheeler Avenue to the Private Road and installation of the Private Road.

The completed project features NCAA-compliant baseball field and softball fields, each with bleacher seating for 300, team dugouts, bullpens press box and digital scoreboard; two (2) softball and baseball steel framed batting cage structures with metal roofing, high-performance tunnel nets and light fixtures; site work including two parking lots, fencing, landscaping, walkways, on-site lighting, and a multipurpose field with Musco lights to be used for intramural sports. The facility building includes baseball and softball locker rooms, showers/team rooms, public restrooms, drinking fountains and a training room (shell space) and was constructed of CMU block.

Children’s Institute of Los Angeles, Inc. – Sports Court

Children’s Institute, Inc. (CII) has created one of the nation’s strongest models for working with children, youth and families who have been affected by violence. For more than a century they have served the most at-risk and oft-overlooked young people in Los Angeles — those harmed by child abuse, neglect, domestic violence, gang and community violence.

Oltmans Construction Co. was brought on board to provide general contracting services. The scope of work involved the demolition of existing retail stores, grading and construction of a post-tension slab NCAA size basketball court complete with basketball hoops, scoreboard, benches, hi-tech fencing and volleyball nets.

Juniper Springs Lodge

175-unit three-story building condominium complex with two-story subterranean parking structure. Also included: exercise room, swimming pool, locker rooms and café. Extensive exterior architectural enhancements. Oltmans worked closely with Callison Architects of Seattle, Washington during the design phase, providing value engineering and constructability review. Oltmans’ team provided design / build services for the mechanical, electrical, plumbing and fire sprinkler scope of work, as well as full general contracting services for project. The site is located in the Sierra Mountains near the Mammoth Ski Resort area. A significant portion of the construction operations were completed during the winter months with up to twenty feet of snow. Temporary protection and precise sequencing were necessary to meet the construction schedule deadline during the inclement weather conditions. The soil conditions included heavy rock and boulders which required blasting to remove them and subsequent de-watering operations with a storm water recovery system. The site is adjacent to the Valentine Timber Reserve, as well as the local water supply, Mammoth Creek. The close proximity to these two sensitive areas required significant water runoff mitigation and quality control systems to be put in place and closely monitored. The project challenges were successfully managed with pre-construction planning and teamwork with our subcontractors. The Client was very satisfied with the quality of the project completed on time and budget.

Mariners Church

Winner of “Best of” in the Worship Category from California Construction Magazine.

The Mariner’s Church’s master-planned project was developed in a series of phases. Approximately 80% of the site has been improved or newly constructed from vacant land. The project included the expansion of campus facilities from two existing buildings to seven major buildings plus parking structures and new outdoor facilities and playspace.

The original campus design and first stages of construction started in 1998. Oltmans was brought on board in 2004 to assist with planning and constructing Imagine 3, the third phase of the masterplanned campus, which included the site and lake work, the Youth Building and Port Mariners Kids Building. The new chapel was under construction concurrently with our phase of work and required collaborating with the other on- site general and subcontractors. Oltmans coordinated all site logistics for an effective construction operation. In addition to general contracting, Oltmans provided design/build services for the mechanical, electrical, plumbing and fire sprinkler systems. We worked closely with the lead design team, which included the lead campus designer, the lead architect for all vertical construction and the specialized chapel designer.

The two-story steel framed Youth Building included large multi-purpose rooms with state-of-the-art sound, video and lighting for the performing arts stage. Recreational areas included meeting rooms with roll-up doors to connect with the youth plaza outside, lounges for high school age youth furnished with pool tables, table top games and other equipment for interactive recreation. There was a 2-level basketball court structure as well as a large skateboard/bike park located outdoors in the student plaza. The studio space was designed for students to listen to music, record music or practice for upcoming performances. Class room and office space was also included.

The two-story, 72,162 s.f. Port Mariners Kids Building was a tilt-up concrete structure with a stone veneer, glass and aluminum façade. The project included class rooms, central plant building with mezzanine as well as Wacky World Studios props and decorations as well as a custom themed play ground.

The site and artificial lake scope of work included a 3-acre man-made lake with a concrete bottom. The lake area included waterfalls, bridges, trellis structures and decorative concrete. One side of the lake wraps around a barbecue island for outdoor events. The campus site setting was designed to accommodate special occasions, including weddings and other gatherings. The lake design created a protective type moat, separating this area from other activities and crowds.

The California Speedway

California Speedway is a 2-mile, low-banked, D-Shaped oval super speedway in Fontana, California. Oltmans Construction was contracted to construct two separate projects for the master plan. The first project, The California Speedway Support Buildings, was constructed using masonry with steel joist and metal deck roof structures. The project included approximately fifty (50) individual support buildings at a total of 360,000 s.f.; including: race control tower, souvenir buildings, ticket buildings, security buildings, an urgent care facility, 35,000 s.f. maintenance building, three (3) state-of-the-art garage buildings, three 2-story infield corporate suites including interior improvements, twenty-eight (28) sky boxes, chalet kitchens, concessions, 40,000 s.f. administration building, locker rooms/showers and nine (9) public restrooms. The second project was the California Speedway – Grandstand Expansion project, which consisted of the construction of additional bleachers as well as included three (3) additional retail buildings and an elevator tower at 4,200 s.f. Oltmans self-performed the concrete work around the race track and provided the foundation, slab on-grade for the support buildings.

The California Speedway was a Kaiser Steel Mill superfund site and the area below the pit buildings, built by Oltmans, has an environmental barrier condition.

Roger Penske is well-known for his high standards and attention to detail. He had this to say about the quality of our work on the California Speedway, “Your team’s perserverance produced buildings that are being lauded as the best in motorsports.” Penske Vice President Chairman Walt Cszarnecki added, “It was a great team effort.” California Speedway opened in April ‘97 to national acclaim.
