The free-standing, one-story building features a spread footing
foundation with a grade concrete slab, a hybrid steel and wood structural system, and a steel roof support structure for a single gable roof with front-facing intersecting gables.
Once the outlet structure was lowered into position and suspended a short distance above the bottom, the barge carrying the trimmey and concrete truck was floated into position to pour a spread footing
on the lake floor beneath the structure and to fill the box containment structure with concrete to provide ballast.
Areas covered include reliability-based design, LRFD concepts, in situ soil testing, geotechnical design of combined spread footing
, design of drilled shafts, and stability analysis and design of slopes.
A concrete foundation typically is comprised of two parts: the spread footing
and the stem wall.
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.
The first example is a 74-meter (m), reinforced concrete box girder, two-span overcrossing with spread footing
5 foot by 83 foot bridge is a continuous 3-span reinforced concrete slab with reinforced concrete pier walls and reinforced concrete diaphragm type abutments all supported on spread footing
Tenders are invited for work includes approx 5 ea of construct spread footing
when conditions do not allow drill shaft; 24 ea of install new pedestrian lighting fixtures; 5 ea of remove and relocate lighting fixtures; 5 ea of remove existing concrete footings; 160 lf of coordinate with centerpoint to determine conduit size, furnish and install conduit with pull string, etc; 1 ls of furnish and install control boxes, panels, conduit, conductors, etc.
construction includes slab on grade with concrete spread footing
foundation and a steel framed structural system with metal stud infill and metal panel exterior, along with metal panel roofing.
complete removal of an existing multi span timber bridge and theconstruction of a new single span voided slab concrete structure founded on a reinforced concrete cast in place spread footing
The shelters will require either spread footing
or piers and in areas where a standard four corner anchored attachment would block sidewalk or merchant access "work arounds" will be required.
shallow, reinforced concrete spread footings
will be used.
