4 1. Observation and illustrations [pictures will be provided where necessary/ required]: 1.1. Contract No.1: Observations: Reservoir construction was barricaded during the site audit [see Figure 3] Compliance. Construction rubble should be temporary stockpiled in a designated area on site. no barricading around the stockpile was noted [see Figure 4] Non-compliance The contractor is advised to ensure that topsoil is not exposed to construction material stacked/ placed on site. Topsoil stockpile must be barricaded at all times to prevent from contamination [see Figure 5] Non-compliance Pipes temporary stacked on site, contractor is advised to ensure stacking is in a designated area and should be barricaded [see Figure 6]. In-appropriate disposal of construction rubble [cement] on site. The contractor was advised to ensure that material [cement] is collected and appropriately disposed of site, waybill for safe disposal is to be placed on file for compliance [see Figure 7] Non-compliance. Open trench was barricaded, and the separation of topsoil and sub-soil noted [see Figure 8] Compliance. Recommendations: The contractor is advised to ensure that material stockpiled on site does not encroach on site topsoil. Material must be barricaded at all times to prevent from contamination. The contractor is advised to use shutter-board when mixing cement and ensure that material [cement] does not harm the surrounding environment.
