Boeing Commercial Airplane Group
Renton, WA
Renton Apron A& D New Crew Shelter & Guard house
Proposed Construction Dates & Times:
The proposed construction schedule will begin in Early September 2015 and end in late
November 2015. The work will be accomplished during daylight hours, typically starting
at 7:00AM and completing at 4:00PM, Monday through Friday.
No late night hours are proposed for construction and hauling activities. Potential
Saturday hours may be required.
Construction Description & Work Plan:
1) The project consists of an installation of a new 12’ x 30’12’ High crew shelter
with new underground data and electrical utilities. The Crew Shelter will be
equipped with an exterior amber hued directional light and a ADA ramp.
2) The project will also have a new smaller guard house relocated from a temporary
location and installed on Apron D. The old guardhouse will be removed due to
obstruction with the wings of the new larger 737 max aircraft as it taxis through
the Apron. The new guard house is 8” x 10 “by 8’ 6” high with new data and
electrical utilities.
Construction Mitigation Measures & Best Practices:
All activities will begin with the implementation and installation of Best Management
Practices (BMP)). These practices include:
Proposed Hauling/ Transportation routes Contractors will apply for their own
hauling permits related to this project. And will follow a city approved route.
Construction.
The actual Construction will be accomplished by a Construction contractor.
The contractor will call for all required inspections, as well as site pre-construction
meeting. The contractor will keep records of any special inspections at the construction
site
Storm Water Construction will start with the implementation and installation of
Best Management Practices (BMP) for Temporary Erosion and Sedimentation Control
(TESC) under supervision of Boeing Environmental personnel. All storm water drain
inlets in and around the proposed construction operations and staging areas will be
surrounded by oil absorbent padding to mitigate the potential of any hydraulic/fuel
leakages emanating from construction machinery entering the watershed
Snow, Ice, dirt and mud removal Contractor shall remove snow and ice to the
extent necessary to perform the work. The use of calcium chloride or other chemicals will
not be permitted to remove snow or ice. Contractor shall assure that vehicles are
constructed, loaded, maintained and covered as necessary to prevent the deposition of
dirt, mud or other debris on public roadways. Dirt mud or debris shall be removed on
continual basis. Any dirt, mud or debris dropped by vehicles shall be removed
immediately.
Dust Control Through the entire construction period the Contractor shall take all
necessary steps to dust control all working area and unpaved roads. The use of calcium
chloride or other chemicals will not be permitted for dust control. The Contractor will
accomplish dust control by watering and sprinkling to satisfactorily settle the dust.
Contractor shall comply with any requirements imposed by law to prevent fugitive dust
emissions. All demolished materials and debris will be stockpiled on site to prevent dust
and sedimentation from migrating onto roadways. Contractor vehicles that are
transporting materials to and from the site will be required to have tires washed prior to
leaving the site. This will prevent dust and sedimentation from entering nearby
roadways.
Environmental Protection
All motorized construction equipment will be inspected daily for
petroleum/hydraulic fluid leaks and any leaking equipment will be removed from the
site for repair.
Drip pans/pads will be placed beneath motorized construction equipment left on site
for the duration of the project.
A spill kit will be kept on site to contain and clean-up any chemical/petroleum spills
Airport Mitigation
A pre construction meeting will set up with the Airport personnel.
The contractor will set up visual controls, and FOD* controls including a FOD* fence.
