INJO SLIP MAINTENANCE PROGRESS UPDATES

INTRODUCTION This report regards the work progress on site at Injo Slip Maintenance. The work/maintenance carried out by Roadworks Supervisors, Contractors and Labours engaged have each played their part to at least complete the Scope of Works prepared to repair the defective Corrugated Metal Pipes and do backfilling of boulders and gravel along the slumped affected sections of road. However, the progress of maintenance work was delayed due to some minor issues such as, Labour Pay Issues, Operators not Turning up for work or Late, Funeral Services, and Trucks not on site, etc… BRIEF UPDATE We started working on the 1st defective culvert as per recommended by Geotech Reports. The existing defected 1800mm dia. CMP was replaced with a 1500mm dia. CMP. All features and steps taken to install the 1500mm dia. CMP and backfill were done accordingly to recommendations from Geotech Engineer. Due to the minor delays, we have not constructed the gabion basket headwalls at the intake and outfall areas of newly installed 1500m dia. CMP as per recommended by Geotech. Figures below could picture the frame of work carried out so far. The remaining works need to be executed this week and next week will also be executed accordingly to the duration and plan we are working towards in line with the Geotech Engineers’ recommendations.
