the project is comprised of, but not limited to: demolition and removal of existing asphalt pavement and excavation for the runway and bollard foundations; construction of concrete grade beam
on auger cast piles runways, with tie-downs; construction of concrete bollard foundations and hardware with auger cast piles; patch and repair of existing asphalt pavement damaged by construction; and any supportive ancillary tasks to successfully complete all phases of the project.
Oldcastle Precast was contracted by Dick Anderson Construction to design, engineer and manufacture fifteen precast concrete tri-deck bridge girders, six precast concrete grade beam
abutments, and twelve precast concrete wing walls, at their Spokane, Washington plant.
For piers 12 and 13, the contractor constructed a reinforced concrete grade beam
supported by the concrete drilled shafts, which extended to the outer reaches of the bridge.
The building's structure also utilizes reinforced grade beam
foundations and a slab on grade.
The construction process encompasses excavation, construction of grade beam
and spread footing foundations, erection of a hybrid steel-and-light-gauge structural system, building and MEP systems, and all interior finishes.
Normally, a large grade beam
sits 12 inches below the finished floor of the home and would prevent a waterfeature from flowing underneath a wall or window.
A typical grade beam
is 1 foot square, but dimensions vary depending on the situation.
You'll be able to make the fine adjustments when you attach the 2x6 grade beam
ledgers to the 4x4 grade beams
along the sides of the 230-ft long structure, and a four-ft by 12-in.
The "rubble trench" foundation employs compacted gravel below a grade beam
, on which your structure is built.
They bear on a perimeter grade beam
and are restrained by ties to stainless steel rods cast into the concrete wall panels and, in the areas which are framed, by brackets from the steelwork.
Where possible, grade beam
exteriors should be set with their exterior edge flush with the building face.
