Bellevue City Hall East Garage

General Contractor: Pacific Earth Works Inc.

 

Description: This project was more than 11,000 square feet of intensive green roof on the fifth floor of a new garage addition to the Bellevue City Hall building. The main structural work was done by Lydig Construction Company, Inc. who worked closely with Pacific Earth Works to accomplish a seamless installation of the new addition.

 

This project was complicated in that approximately 450 cubic yards of growing medium was blown up to the fifth floor by Bark King Blower Truck Service with their high powered rock truck. In addition to the soil another 1500 bags weighing 50 lbs. each of Mexican Beach Pebbles were hand placed onto the roof. During all construction the main City Hall building remained open to add to the technicality of this installation.

Description: Landscape and green roof installation as part of new building construction. At-grade landscape scope included excavation and removal of native soils within right-of-way planting areas and Corten steel planters, deep import soils in all areas, design-build sub-surface automatic drip irrigation system, root barrier at street trees, tree installation with staking, shrub and ground cover installation, aluminum edging, crushed granite walkways, and bark mulch. Rooftop scope included drainage, design-build sub-surface drip irrigation system, deep import soils, and planting within free-standing rooftop planters, planted-in-place green roof tray system with design-build sub-surface pop-up spray irrigation system, aluminum L-shaped edging at all green roof vegetation perimeter edges, drain access/inspection boxes with gravel ballast and edging, sedum tile planting.

 

 

 

 

South Lake Union Office Park

General Contractor: Pacific Earth Works Inc.

 

Description: This project was another tech based office building in the South Lake Union Area in which the owner is committed to not only providing an exceptional landscape for its tenants to enjoy, but also providing open public space for Seattleites to enjoy.  The plaza space created between the two office buildings was unique in that there was a glass ceiling colored green which emitted a greenish aura to the sidewalk and landscape below.  It has a sort of airy, and jungle feel to it while also being surrounded by a highly urban office building setting.  The plant pallet was exceptional in local diversity and texture that it provided.  The 6th floor rooftop terraces were created to provide the tenants a useable and almost living space with plenty of seating, a fire pit, barbecues, and amphitheater type seating for exterior presentations.  The landscape here served as a unique backdrop of pines and grasses amongst a smattering of other unique plant choices adding color and textures.  There was also a 5th floor bridge between the building that added a unique Corten elevated planter with Coral Bark maples and Liriope.  We also installed 18 very large Glass Fiber Reinforced Concrete planters with the approx dimensions of 4’ wide x 3’ deep x 10’ long.  These were very large and heavy but added a unique element to the project.
