Method Statement - Installation and MEP of Manual & Electrical Shutter Doors

Introduction

The below mentioned scope of works is a comprehensive step by step mechanism for demolish and installation of shutter doors. The under discussion scope of works also encompasses general MEP Services of shutter doors.

Start of Works

Installation Technical Engineers must report to client/worksite office on arrival at the project site/facility.
Engineers must attend site technical and HSE induction if they are instructed to do so.
Prior the work start, Engineers must wear the correct PPE required for the job and/or as instructed by client/customer site.
Project or Installation Engineers must establish a prohibition zone using hazard warning tape and safety cones prior to works starting.
Engineers are to use only correct equipment for all access as dictated by the job and/or instructed by client/customer.
Engineers are to inspect and assess the requirements of the task. If dismantling of existing door is required, following step 2 first; if not required, follow step 3.

Dismantle Process

Visually inspect the area and ensure exclusion zone is in place.
Bring in all required equipment and materials into exclusion zone.
Bring the shutter door down to ground level (Manually or use of power).
Disconnect and isolate electrical power supply.
Position and secure ladders on either side of the shutter door (depending on height and width of door, scaffold tower maybe required central to the door).
Remove front canopy and inspect fittings including top clips.
Remove guide rail on one side to get approach to edge of shutter door.
Slats or Laths can now be removed in sections from the bottom up to barrel.
With help of portable secure ladders, remove top clips from barrel.
Cut off or disconnect barrel and motor from flags taking the weight in the process and bring to ground level (floor).
Eliminate or discard guides unless they are going to be used for the installation of next door.

Installation Process

Visually inspect the area and ensure exclusion zone is in place.
Bring in all required equipment and materials into exclusion zone.
Ensure power is disconnected and isolated.
Position and secure ladders on either side of the shutter door (depending on height and width of door, scaffold tower maybe required central to the door).
Install guide rail and flags.
With the help of portable ladders lift barrel into right position and secure to flags. If manual winding mechanism system, set pre-tension when installing barrel.
If winding mechanism system, locate and secure winding mechanism into place.
Reexamine that guide rail and barrel is properly secure ready for attaching shutter door.
With the help of portable ladders attach top clips and top slat/lath to prearranged holes on the barrel.
Ensure top clips are secure and working down attach sections of slats/laths to requirements.
Review and recheck that all parts are in correct order and all working parts have been lubricated properly ready for testing.
Prior wiring into mains, test motor and set limits via a test switch or test winding mechanism system.
When testing has taken place and limits are set, motor will be connected to mains.
Conclude one final check of installation and attach front canopy.
Clear area by maintain good housekeeping and report to site contact for hand over.

General Maintenance and Servicing

Visually inspect the area and ensure exclusion zone is in place.
Bring in all required equipment and materials into exclusion zone.
Visually inspect and test door operation.
Visually inspect guide rails.
Disconnect and isolate electrical power.
Manually feed shutter curtain downward to expose top clips. Then visually examine expose top clips.

If Top Clips show sign of damage:

Report promptly to client/customer and person in charge of area of possibility of collapse of curtain / shutter.
Make all persons within close proximity of potential possible severe hazard.
Make arrangements to repair / change top clips.

If there is No damage to top clips:

Check shutter curtain edges for any damage.
Check guide rail for damage. Replace if required?
Lubricate moving components with WD40 and/or Grease.
Manually test door operation.
Visually inspect and re-test again.
Reconnect power and test under load.
Door will be tested and inspected for correct operation, up and down, using the motor and/or winding mechanism.
If door is operating as intended and correctly, report to site contact and hand over.

Hazards to Report:

Damage to top clips
Damage to guide rails due to mobile plant and or vehicle contact.
Damage to curtain and or shutter due to mobile plant/vehicle contact.
Damage due to vandalism

Clear Worksite

All waste is to be cleared from site. Metal components must be loaded onto works van.
Plastics sheets and warning hazard tape to be removed to waste bins.
Engineer and worksite contact to inspect area before works assumed to complete.

Note:

On very rare occasions a Hiab lorry maybe used to lift heavy barrels or shutter doors. Only authorized and competent persons will use the Hiab. The use of the Hiab will be controlled within process 2 or 3 depending on requirements. Where lubrication is required, substances will be used accordance with COSHH assessments.
