The Crossing – Phase I & II

Oltmans provided construction to the 21,000 s.f. church consisting of a two-story 1,300 seat acoustically controlled auditorium and innovative audio-visual/lighting system. The site work included the excavation of an open pit in order to build the below-grade auditorium. This project was modeled using the BIM delivery process. With the challenges in the horseshoe shaped auditorium design, the BIM model provided time and money saving insight for the structural steel detailing portion of the job and the installation of the Mechanical, Electrical, Plumbing systems as well as other components of the job. This project was also built around an existing auditorium that was being used for church services. This presented a unique challenge as the new church encroached into this existing auditorium. The BIM model provided valuable information on which portions of the new church could be built while maintaining the use of the existing auditorium. Other unique design features of this project included a state-of-the-art audio-visual and lighting control system. AV system consists of more than 70 speakers, 35 HD TV screens and an HD TV projector. This system is installed in the 1,300 seat auditorium, where every seat has a view of one of the 70-TV screens. The innovative lighting package is a computer-controlled system and includes the extensive use of energy saving LED lights.

Village of Hope

Village of Hope

This Design-Build project was part of a base closure project at the Tustin Marine Base. Once a Military Barracks Facility, the project consisted of converting housing for occupancy by homeless families and building new structures for dining and classrooms. The Village of Hope is a nationally recognized residential facility for homeless men, women and children. It is the most comprehensive facility of its kind in Orange County, California and serves as a national role model for the re-purposed use of closed military bases. Located on five acres of the former Marine Corps Air Base in Tustin, this complex consists of 150,000 s.f. of living and learning space.

The Village of Hope offers tastefully appointed residential suites cleverly converted from their original military barracks into housing with an overall capacity of shelter for 192 needy residents. This multi-function center also provides fully-licensed medical and dental clinics, a child development center, oversized dining facilities, a 290-seat chapel and auditorium as well as a variety of other vocational and counseling classrooms. Oltmans Construction Co.’s scope of work included, but was not limited to the following: Construction of the spectacular new chapel and dining facility, all related site work required by the project, the addition of elevators in existing buildings, and conversion of the military barracks into residential suites. In addition, significant structural and utility modifications were required and made to the medical offices, classrooms and training facilities.In addition, Oltmans Construction Co. coordinated and managed all donated materials and services for this project. Self performed work also included concrete, light carpentry, framing, seismic, structural retrofit, demolition, materials waste management, and site housekeeping.

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.
