PROJECT
The project involved the complete construction of a new 30-unit condominium complex in Coeur d'Alene. The building was constructed of structural steel, pre-cast concrete, and cast-in-place concrete set on Driven "H" piles. A large amount of uncompacted fill exists on the site, which was used to build up the sea wall and the remainder was stabilized using deep dynamic compaction.
SCOPE
Our scope of work for the projects consisted of the following.
Earthwork. A soils technician was present during filling operations. Field density tests (compaction) were performed by nuclear methods on subgrades, each lift of fill or backfill placed in building or paving areas, retaining walls, and over site utilities. Samples of onsite and borrow soils were obtained and laboratory tests were conducted to determine suitability and maximum density/optimum moisture.
Deep Dynamic Compaction. A Budinger Special Inspector/Engineer was present during deep dynamic compaction operations to verify compactive effort, spacing of drops, and record locations. We worked closely with the geotechnical engineer (F.C. Budinger) and helped in following his recommendations and project specifications.
Driven "H" Piles. Our Engineer was on site during pile driving to monitor placement, blow counts, and soil/rock conditions.
Reinforced Concrete. A Budinger Special Inspector was present to examine forms, reinforcing steel, embedded items, anchor bolts, and epoxied anchors, and to perform concrete placement inspections, conduct slump and air entrainment tests, and cast compressive strength specimens during structural concrete placements. Samples were collected the following day and returned to the laboratory for curing until test age. Testing and specimen molding during miscellaneous concrete placements (slabs on grade, sidewalks, curbs, etc.) were conducted at the discretion of the client.
Structural Steel Erection and Field Welding. A Budinger Special Inspector visited the site initially, at the beginning of erection, to verify the qualifications of welders and examine materials and site conditions. Periodic site visits were made to examine full penetration welds and test welded and high-strength bolted connections.
Structural Steel Fabrication. A Budinger Special Inspector was required to perform similar examinations at the fabricators shop.
Spray Applied Fire-Resistive Materials. A Budinger Special Inspector inspected fireproofing materials during application, performed thickness measurements, and collected samples for laboratory testing.
Asphalt Concrete Pavement. A technician was present during paving operations to monitor placement and compaction and sample hot-mixed asphalt concrete for asphalt content, sieve analysis, and maximum density.
