Kier + Wright has designed extensive on-site and off-site improvements for developments within Facebook’s West Campus, an ongoing expansion of Facebook’s corporate headquarters in Menlo Park. The MPK 21 development is a 24-acre portion of the West Campus that includes a 500,000-square-foot, LEED Platinum-certified office building with a green roof. Kier + Wright provided civil design and surveying services to support the planning and construction of MPK 21 and its associated off-site improvements.

Specific scope items provided include topographic survey, mapping, grading and drainage design, utility systems design, stormwater treatment design, stormwater maintenance agreements, stormwater calculations, hydrology calculations, hydraulic calculations, 3-D modeling, construction administration and construction staking

The development was notably constructed in only 18 months. Planning and design proceeded on an accelerated timeline to accommodate Facebook’s building occupancy schedule. Kier + Wright prepared several construction-level engineering packages that helped allow the project to begin construction prior to formal building permit issuance.

MPK 21’s proximity to the San Francisco Bay added complexity to the design of site work. To avoid risk of flood damage, the building and finished floor are raised to clear the FEMA base flood elevation and the 50-year sea-level rise elevation. Its utilities are installed within the groundwater. Kier + Wright prepared buoyancy calculations to confirm that all wet utilities would remain securely in place and resist the effects of the groundwater at its existing depth and at the depth anticipated given the 50-year sea-level rise.

MPK 21 features a 3.6-acre green roof with over 200 trees, an amphitheater and a walking path. Kier + Wright’s drainage and utility plans route the green roof’s run-off to various locations. Stormwater run-off treated on the green roof is routed to underground storm drains; surface water draining from the green roof’s impervious surfaces is routed to a ground-level bio-treatment swale.

The LEED-certified building features a recycled water system designed to reduce annual water use by an estimated 17 million gallons. An Aquacell system inside the building treats and filters blackwater to be safely re-used in irrigation and in the building’s toilets. Kier + Wright’s utility plans included a dual sanitary sewer system with shut-off valves that ensure that any untreated blackwater would properly route to the City’s sewer system in the event of a failure or overload of the on-site system.

The owner, contractors, and architect required various levels of 3-D modeling support for different design, construction and simulation purposes. In addition to preparing 3-D modeled wet utilities and sitework, Kier + Wright created Revit surfaces for various site elements.

Kier + Wright’s off-site scope included design of approximately 2,000 linear feet of utility infrastructure, such as storm drainage, water lines, irrigation lines and sanitary sewer. Kier + Wright also prepared plans for various off-site pedestrian paths and for a bicycle path along Chilco Street.

The American Council of Engineering Companies of California has selected Kier + Wright to receive a 2020 Engineering Excellence Merit Award in recognition of civil design services provided for the MPK 21 project.

Kier + Wright has also provided engineering and surveying services for the planning and on-going construction of MPK 22, an additional West Campus office building. The firm is also currently designing site work for additional developments within the West Campus, including a multi-level parking garage structure and an outdoor recreation area with a plaza that will be open to the public.

  • Corporate Campus
  • Office
Highlights
  • Prepared calculations and provided technical input for the project’s environmental impact report.
  • Provided sustainable stormwater management design and prepared stormwater calculations for this LEED Platinum-certified project.
  • Site is located on the San Francisco Bay within a challenging FEMA flood plain. Flood elevation and anticipated 50-year sea-level rise influenced utility installation plans and design of sitework.
