Perform pre-construction site assessment SITE ASSESSMENT, GRADING AND DRAINAGE (22 HOURS) A. Pre-construction Site Assessment (4 Hours) Outcome: Perform pre-construction site assessment. Site evaluation The contractor shall inspect the site prior to starting work to verify that all surfaces are properly prepared and graded. Upon discovery, any discrepancies shall be reported to the authorities. See city of Red Deer notes. City of Red Deer Contractor Scope Document Level 1 Site Assessment.pdf No landscape work shall be carried out in areas or over surfaces that have not been properly prepared and graded. Identify site hazards.

Chapter 2: Construction Site Assessment & Planning [PDF] Dependent on the development site. A new subdivision will be stripped and then the subgrade set to allow for planned drainage. Topsoil will then be added once construction of the subgrade and any buildings has been completed. Acreage developments will be more complicated Site elements and conditions may include, but are not limited to: Trees and other vegetation Water: Surface and subsurface Growing medium and subsoils Fauna Historical or archaeological elements Geologic formations Other important natural or man-made elements Identify security requirements. https://broomfield.org/DocumentCenter/View/3380/Construction_Site_Security_Survey_Checklist?bidId= Construction Site Security: The Ultimate Guide Typical threats for a construction site. Threats that may be considered typical will vary according to the type and location of the site. The following are suggestions but each site will be individual. Theft of plant Theft of fuel Theft of materials from the site Vandalism Arson Breaches of security into existing buildings Robbery or attacks on the construction workers Reconnaissance of development to discover details of completed building Bombs (perhaps planted for detonation after completion) Intruders intent on committing suicide Protesters (either related to the site activity or simply for publicity) Whilst considering threats the risk assessment should take into account hazards. The following hazards are typical: Flooding, storm damage, etc Project issues (Staff injury, Failure of supplier’s business, Finance, etc) Construction Site security checklist Construction Site Security Checklhttps://drive.google.com/file/d/0B_3BY5GuNMnbWGVMOHFMYU1WaGk1M2NyLVRiRXhVLUZfV0sw/view?usp=sharing&resourcekey=0-gJNNLoGLtG25y2S9-F49_A ist .pdf Identify site access. There may be a report from the initial site visit by the estimator. Visual inspection Google maps Describe site-specific information required to complete project tasks. Is there water available? Is there access to electricity? What else may you need? Perform visual inspection of the site and neighbouring properties. Take notes and photographs/videos to substantiate pre-existing site conditions Perform a site hazard and security assessment.
