Portland Portal, Phase II is a multibuilding industrial park in Gresham that was developed by Panattoni Development. Sierra Construction broke ground on the project in June 2018 and completed it 14 months later. The 22-acre site has three buildings totaling just under 360,000 square feet of warehouse and manufacturing space.
With more than a 50-foot elevation change, the site itself was a challenge. Sierra Construction dealt with the steep slopes by utilizing the building walls as retaining walls with the finished floor up to 14 feet below exterior grades.
Building A is 110,000 square feet with 21 dock-high doors. Building B is the smallest at 47,000 square feet and 10 dock doors. Building C, the largest of the three, is 203,000 square feet and has 46 dock doors. All three buildings have a 30-foot clearance height. The site has more than 300 parking spaces.
Sierra Construction also built the 130,000-square-foot manufacturing facility and warehouse just to the east that is a distribution center for Mary’s Harvest Fresh Foods.
