Project Completion: Des Moines Creek Business Park, Phase IV

Phase IV of the Des Moines Creek Business Park is situated on Pacific Highway, and included the construction of two new industrial buildings. Previously occupied by Furney’s Nursery, the 22.5 acre site now has over 512,000 square feet of new industrial warehouse space.

Sitework included moving over 350,000 cubic yards of dirt and the installation of two ground water detention tanks; 230,000 gallon onsite detention with 170,000 gallon north detention tank and wetland vault. Due to the sloped site, additional features included a 14,000 square foot lock-load wall, and a 1,300 linear foot 13’ rockery wall. One of the value engineering ideas that the Sierra team brought to the developer and design team was to slope the Building A slab by 0.5%. This provided a change in elevation of 3 feet over the length of the building substantially reducing the cut to fill earthwork and retaining wall quantities. Both buildings were built with concrete tilt-up construction, with a 36’ clear height on a 7” slab.

Building A was the first building to tilt with 92 panels, each weighing up to 87 tons. Located on the north end of the property, the footprint of this building is 266,000 square feet with 45 truck doors. The 246,000 square foot Building B was constructed with 86 tilt panels each weighing up to 83 tons, and features 34 truck doors. A total of 34 greenscreen cast-in-place planters span the walls of both buildings.
