Summarize the project's program, features, and achievements: The Master Developer began redeveloping the previous March Air Force Base known as the Meridian Business Park in 2015. Upon completion the development will include four (4) planned phases featuring 16 million square feet of building space and is anticipated to create up to 15,000 jobs boasting some of the top tier companies and businesses in the world. Oltmans completed Phase 1 of the Meridian Business Park which includes three (3) speculative concrete tilt-up warehouse & distribution buildings and two (2) build-to-suit distribution centers for Safavieh and e-commerce giant Amazon known as the DJT6 Gen3 Delivery Station. Upon completion the Meridian Park South project totals 3.5 million square feet of building area. Building A – Amazon LGB6 1,002,189 s.f. Building B – UPS 1,000,400 s.f.; LEED Silver Certified Building C - Safavieh Build-to-suit, 500,174 s.f. Building D – RDNC 782,209 s.f. Building E - Amazon DJT6 Build-to-Suit – 219,928 s.f.

What obstacles were overcome related to the schedule, budget, program, specification, site, etc. on this project? Construction of the Meridian Business Park South spanned the global COVID-19 pandemic shutdowns. This affected the project’s ability to procure materials causing significant delays. To mitigate time lost, the team reconfigured the construction sequence to keep the project moving. As a reputable union contractor in the Inland Empire, Oltmans Construction Co. controls a field force of approximately 400 carpenters, allowing us to exert strategic control of the schedule and meet manpower requirements despite a severely constrained labor force due to the pandemic. With the implementation of proper state and federal COVID guidelines, the project team was able to avoid schedule disruptions and delivered the project on time.

Please communicate any engineering complexities or unique features of the panel design for this project. ? Our biggest engineering challenge was furnishing and installing a geo grid wall at the southeast corner of the site. We had to install this wall during slab on grade and panel construction. Due to potential lateral surcharge, we had to coordinate the panel lift and regular construction traffic with the construction of the wall.

What is the potential for this project's impact on the community and/or environment? Building B, occupied by UPS is a ground-up concrete tilt-up building with tenant improvements for approximately 1,000,400 s.f. of industrial distribution. The project was awarded LEED Silver certification and features K-25 sprinkler head, ESFR Sprinkler System which meets the LEED Certified construction foreign trade zone minimum. Building E, Amazon DJT6 is a ground-up, build to suit, single story, Gen3 Delivery Station with exterior van loading and canopies for Amazon DJT6 Last Mile Delivery Station. Oltmans’ project scope included construction of the main shell building, Amazon T.I. build out, all site walls and fences, site light standards, traffic signal, 442 EV chargers, solar panels, and other miscellaneous site improvements. The successful completion of the Meridian Business Park South projects also facilitated critical warehouse & distribution logistics demand throughout the Southwestern United States as the COVID-19 pandemic shutdown heightened demand for e-commerce and online ordering. In addition to meeting the demand for premiere warehouse and logistics in the Inland Empire the Meridian Business Park is also anticipated to bring in over 15,000 high-income jobs to the Riverside and local community.
