BASICS ARRANGEMENT FOR THE FLOOD PREVENTION FOR TEMPORARY TRAFFIC DIVERSION IN MIDDLE EAST

SAFETY FACTORS TO BE CONSIDER FOR THE PREPARATION AND ADVANCE NOTIFICATION TO (CONTRACTOR OR SUBCONTRACTOR OR MANAGEMENT NAME HERE) FOR THE FLOOD PREVENTION PLAN AND ITS IMPLEMENTATION.

We are hereby attaching the updated (procedure or plan references ) for inclement weather procedure or plan and associated aspect. We are acknowledging you by the letter to abide by the procedure incise of any event flood emergency and related asper during the rainy season. Planning and preparations for Flood prevention in the (Project name here) ROW, forecasting the severe inclement weather which could potentially interrupt the traffic in the diversion roads, neighbouring residents to the works place and the onsite permanent works. (Contractor or subcontractor or management name here) shall plan their work and flood prevention plan forecasting the rainy season considering the following but not limited to;

Diversion Roads and Inundation Spots

• All barriers are placed and aligned as per the (Legal or project guidelines) and leaving space underneath to avoid any waterlogging in the road and if any stockpiles in the gap shall be cleaned and regularly checked to make sure no blockage.
• Ensure the ground level behind the barrier near the diversion roads must be below from the street level.
• All excavations/trenches behind and near to the traffic barrier shall be backfilled before the rainy season if not all protection measure may take from accumulating water and edge collapse.
• Lagoon to be provided at relevant areas of diversion road (Hot Spot) and to ensure is large enough to accommodate the anticipated volume of rainwater and periodically inspected.
• The adequate number of tankers trucks, pumps, TMA and other traffic arrangements are available and ensuring its serviceability during the raining season.
• Assigning the flood prevention coordinators and their team for each location and conduct a mock drill make sure that the flood a prevention plan is effective or more arrangement to be done.
• The water daring through the gullies within in out limit shall be inspected periodically and cleaned any blockage. Also, coordinate with the drainage network team anticipating any backflow of rainwater.
• Shall coordinates with the drainage department (insert the location names her if available) pumping station and its flood prevention the arrangement at (insert the location name here).
• After each rainfall, all the debris on the diversion road within our ROW shall be cleaned safely.
• Plastic barriers provided must be filled with water and allow spacing for drain rainwater and secure enough to cause any traffic interruption.
• Traffic barriers shall provide with high visibility reflecting tape and flickering traffic safety light. This shall be inspected and maintained throughout the course.
• Flood prevention team shall conduct routine patrolling of the diversion roads and Inundation Spots in (Project name) ensuring a study and smooth traffic which is not limited to the diversion road but also to the neighbouring resident and onsite permanent works.

Neighbouring Residents:

• The work areas must be cordon off with appropriate barriers, fencing, warning signs, adequate lighting provided on the access to resident etc.
• All material at the workplace must be secured from flying off to the neighbouring residents during gusty wind and from unauthorised entry.
• (Contractor or subcontractor or management name here) shall ensure all safety precaution is taken prior to the rainy season and after each rainfall, the contractor shall ensure no obstruction or any conditions put the residents in distress due to the rains such as: falling off the fence, slippery access, waterlogging etc. if such condition occurs that shall be immediately clear off

Permanent Works (Onsite);

• All construction managers and leads shall plan their onsite flood prevention considering;
• Water accumulation in Underpasses
• Water accumulation in Excavation and Trenches and on it edges
• Site accesses becoming swamp and slippery
• Waterlogging in the parking slots
• Temporary site electric services and equipment lead to electrical hazards
• Another low area of the site that could lead to waterlogging
• Materials fly off during gusty wind and damage due to rain
• Lifting operations etc.
• The collapse of structures including scaffolding and shoring etc.
• All the deep shaft for the micro-tunnelling could affect by waterlogging on the edges and further accumulating in the shaft causing damages to the equipment and services of tunnelling. And from any stress on the edge shaft due to waterlogging during the rainy season that could settle edge etc.

As stated above the work shall be a plan and appropriate preventive measure shall take to prior to the rainy and gust wind season to avoid any severe occurrences during the season. Such as onsite flood prevention team, lagoons, water tankers, portable pumps, coordination with dewatering department etc.

(Contractor or subcontractor or management name here) shall develop an action plan consisting of a checklist for the individual locations for the lagoons and its arrangements, flood prevention team and equipment etc. All area must be checked sporadically to ensuring full compliance of (procedure or plan references) for inclement weather procedure and associated aspect.
