how does this improve slope stability? - correct answer Sub- drainage, decreases the saturation of the slope when a slope begins at vertical cut what is done to stabilize the slope? - correct answer removing the upper portions or head of the slope or landslide is the frequently employed technic for reducing the driving forces that cause the failure to occur what are red lights on a site? - correct answer low bearing capacity settlement existing uncontrolled fill slope stability dangerous seismic conditions frost heave constructabilty- piers or piles proposed significate cut or fill groundwater problems foundation red lights - correct answer design not in accordance with geotechnical recommendations foundation location differs from site investigation location foundation plans not adequate or complete low bearing capacity not recognized in footing design compressible or expansive soil on site not anticipated in design water seepage not anticipated in design seismic conditions not documented properly in design or calculations provisions dealing with frost heave not included retaining structures or basement walls without adequate drainage underfloor crawl space not vented or drained when should concrete be placed? and what raises red flags in the design? - correct answer within 90 minutes of adding water at the concrete plant excessive water should not be added at the site, no more the 5 gallons per truck if air temperatures are higher then 90 degrees and the humidity is less then 25 percent , concrete may suffer drying shrinkage cracking concrete should not be placed if air temperatures are 40 degrees and falling unless special cold weather measures are placed foundation grades and drainage must dos - correct answer surface water must be directed away from the foundation area and not be permitted to stand within or adjacent to the work foundations must have and adequate concrete reveal of 4 to 8 inches before the top of the soil is encountered areas around the foundation must slope away to a swale or drainage pipe system that will drain adequately off site slopes should have approximately 6- inch fall within 10 feet from building on all sides for all buildings, including residence site preparation must dos - correct answer site must be cleared of top soil, grass, bushes, trees, old structures, or old pavement trees and the stumps and the major root systems should all be removed and any holes left shall me refilled with acceptable soil using controlled compaction. all material cleared should be removed from site to avoid mixing with new controlled density fill site preparation is a good time to do what? - correct answer see if there is any unrecorded landfill or dump on the site, in which case operations would have to cease until this problem is cleared up properly soil material control - correct answer atterberg limits and size distribution types of sampling control and how to obtain - correct answer large stockpiles of select material: usually found either at a pit or crusher plant are sampled by a frontend loader taking a full height bite from four sides then that pile will be shoveled from four sides deposited on smaller piles clean aggregate: smaller stockpiles are quartered and combining those quarters until manageable size is obtained cone-shaped stock piles of aggregate formed by conveyer belt may have corse aggregate segregated into an outside lower level zone. what does the nuclear meter determine? - correct answer the unit weight of the soil and compared it to the laboratory proctor maximum density how can soils differ besides by color and texture during a proctor curve? - correct answer plasticity or grain size distribution that will have a different proctor curve how can you id a cut from a fill? - correct answer if finished elevations(solid lines) are lower then the original( dashed line) elevations, a cut is required if elevations are higher then original then a fill is required Special Inspection definition - correct answer special inspection is the monitoring of materials, installation, fabrication, erection and placement of components and connections that require special expertise and are critical to the integrity of the building structure what does the 2012 special inspection manual indicate? - correct answer the duties of a special inspector include tasks to complete before arriving on the job site, tasks during inspection, and tasks to complete after the last inspection Prior to visiting the job site, the special inspector should? - correct answer review the statement of special inspections and clarify any questions review approved plans and specifications review the additional requirements from the jurisdiction for special inspections( if any) discuss frequency of progress repots with building official review the project schedule attend any preconstruction meetings determine if any special inspection of materials from a non appro
