RHD Operational Procedure Zonal Operation Wing
Zonal Operations
OP/ZF/3.10 - Flood Damage Management
Purpose and Scope :

This procedure covers the actions to be taken by the Field Divisions in response to a major incident resulting in total or partial closure of a road or bridge.
Definitions :

Major Incident - can be any event that results in the closure of a road for an indefinite period due to damage, or renders it unsafe for use by the public.

Emergency Works - works carried out on an emergency basis by a Zone to enable the road to be re-opened after a major incident

Flood information Cell - An emergency cell operating for 24 hours in Sarak Bhaban under Routine Maintenance Division to receive information of flood damages in different zones.
Responsibility :

ACE - Zone (ACE-Z) - is responsible for maintaining a comprehensive plan to manage a major Incident occurring in his Zone.

SE - Field Circle (SE-FC) - is responsible for ensuring that the Emergency and Incident Management Plan for his Circle is updated each year and necessary Bailey Bridges, materials and equipment are available at suitable places to meet such situation.

Executive Engineer - Routine Maintenance Division (EE-RMD) - responsible for updating the RHD database on major incidents, notifying all those concerned of major incidents and preparing reports and budget estimates for CE-RHD and MoC.

Executive Engineers - Field Division (EE-FD) - responsible for reporting major incidents to EE-RMD, supervising emergency works and preparing reports and estimates for permanent rehabilitation works.
Method :


Following a major incident in one of the Zones resulting in total or partial closure of a road, possibly as a result of erosion or a landslip, emergency works to re-open the road and carry out permanent reinstatement must be undertaken by the relevant Field Division at the earliest opportunity but in accordance with RHD established procedures.

Since emergency works may be required in more than one Field Division at any given time the RHD response to every incident must be co-ordinated by RHD Maintenance Circle. Their procedure for doing this is covered in RHD Planning & Maintenance Wing Operational Procedure OP/MC/2.2, and it follows that for Maintenance Circle to undertake this task the respective Field Divisions must follow a procedure that integrates with this.


Emergency Planning

The ACE for each Zone, supported by the SE for each Circle within the Zone, is responsible for preparing a comprehensive plan to manage any Emergency and Incident in his Zone and keeping the CE-RHD informed about it. He reviews the plan yearly. He ensures that Bailey Bridges and other equipment and materials required to meet such situation are readily available at suitable locations according to needs. He also ensures that such management plan exists in each Division and it is updated every year.

Major Incident Reporting Guide

A Major Incident Reporting Guide has been prepared for use by RHD which includes standard forms that are to be used by the Field Divisions when submitting information to Maintenance Circle about major incidents. The EE-FD for every Field Division should familiarize them with this Guide and ensure that all SDEs, AEs, and SAEs within his Division are familiar with the Guide, as well as ensuring that spare copies of the report forms within the Guide are available for immediate use in the event of a major incident.

Action in the Event of a Major Incident

Following a major incident, which causes complete or partial closure of a road or bridge the relevant EE-FD must report this to his SE-FC and ACE-Z as well as EE-RMD as soon as possible. In the first instance this may be by telephone, but the incident must in any event be notified to EE-RMD by fax or e-mail using Form IR-1 in the Guide on the same day that it occurs.


At the earliest opportunity after a major incident has occurred the relevant ACE-Z will authorize emergency works with a view to making the site safe and / or enable the road to be re-opened. The EE-FD must notify EE-RMD as soon as the road is re-opened who in turn must immediately notify ACE-PMW together with any other organisations that were previously notified of the road closure.

Upon completion of the emergency works the EE-FD should provide EE-RMD with details of the emergency works carried out on form IR-2 in the attached Appendix, whereupon EE-RMD will inform MIS Circle for them to update the RHD database with this information.


Based on the information provided in form IR-1, EE-RMD will prepare and forward to the EE-FD the post-incident rehabilitation form IR-3 for completion. Where the damage to a road or bridge indicates that major costs will be incurred for rehabilitation, EE-RMD may require an independent survey to be undertaken to verify the rehabilitation works necessary.

Upon receipt of the completed form IR-3, and verification survey if necessary, EE-RMD should prepare a report for submission to CE-RHD through ACE-PMW containing an estimate for the rehabilitation works.

Depending on the scale of works involved CE-RHD will refer the matter to MoC for additional maintenance grant.


Upon approval to the budget estimate for the rehabilitation works the relevant ACE-Z will arrange for the design and implementation of the works in accordance with standard Operational Procedures, and upon completion EE-RMD will advise MIS Circle to update the RHD database accordingly.
