Method Statement Template for Epoxy Floor Coating Work.
PURPOSE and SCOPE.
The purpose of this Method Statement for Epoxy Coating works
is to outline and describe in detail the procedure, material and labor required
to undertake the work or activity in a safe and controlled manner.
This activity should be performed with strict compliance and
implementation of Safety Requirements & Procedure, standard practices, and
project specifications to complete the work.
REFERENCES.
- Material submittal.
- Shop drawings.
- Project specification.
TOOLS & EQUIPMENTS:
- Shot blasting machine fitted with dust collectors.
- Grinding Machine
- Industrial vacuum cleaners.
- Low speed mixers.
- Short hair rollers & squeezers.
- Saw cutting machines.
- Small tools, masking tape.
- P.P.E
PROCEDURES:
Prior to the commencement of this activity or work,
necessary work permits shall be obtained as required in the contract condition.
All HSE activities related to the Project, will be based on
the Company issued HSE Management System guidelines.
All quality assurance and quality control activities will be
in line with the specified requirements of the contract and QMS.
PREPARATION/PLANNING:
Approvals.
Before commencing, main contractor
shall obtain the necessary approval for the Epoxy Coating works.
Ensure to obtain the approvals for
the detailed shop drawings for the Epoxy Coating works.
Ensure that this Method statement
is approved by the Consultant.
Ensure that subcontractor is qualified
to carry out the Works.
Ensure that third party laboratory
is approved by the consultant to carry out material and field testing (if any).
Preconstruction Activity.
A toolbox talk will be initiated
by the HSE Team to the personnel who will perform this activity.
Review the relevant documents to
verify whether the preceded activity was completed and approved by the
consultant.
QA/QC Representative will verify
that all the apparatus and instruments used to check the quality of material
and conditions were all calibrated with supporting documents.
Allocate a dedicated Site Engineer
to supervise this activity that will ensure that this Method Statement, ITP,
and other specific documents related to this activity.
Delivered materials should be
verified by the QA/QC Representative and should be inspected by the Engineer.
Store materials in dry area out of
direct sun light and as directed by the material manufacturer.
Limited access zone shall be
provided with entry restrictions to all operatives.
EXECUTION.
Delivery, storage, and handling.
Ensure the materials fully comply
with the approved Material Submittal.
Store all Epoxy coating materials
on raised platforms and under ventilated area.
Substrate Conditions:
Reinforced concrete slab sound
& dry with properly finished surface joints & edges having some surface
undulations that should be relatively flattened before the application of the
epoxy floor coating system.
Surface Preparation.
New concrete or cementitious
substrates should be at least 28 days old and have moisture content not
exceeding 5%.
Prior to starting preparation,
close the area to be prepared to all traffic and other trades.
Run shot blasting machines or
grinding machine onto the concrete surface to achieve medium sandpaper
roughness and open concrete surface pores.
If any part of the floor is
contaminated by oil, grease or fuel, the contamination should be removed before
other forms of preparation are undertaken (if any). (By Main Contractor)
At free edges such as aisle ways
and doorways the floor topping should be terminated properly. (By Main
Contractor)
Minor surface defects exposed
during surface preparation such as shrinkage cracks, blow holes, minor honey
combing, minor damage to joint arises shall be filled with by epoxy mortar.
When floor preparation is
complete, vacuum the area to remove all dust and debris.
Place 50mm wide masking tape along
free edges.
Mixing.
Epoxy flooring is supplied in two
pre-weighed packs (base & reactor), which are ready for immediate on-site
use. Part mixing of these components is
not acceptable and will affect both performance and appearance of the finished
floor.
Mixing should be carried out using
slow-speed drill with proprietary mixing paddle attachment.
The entire contents of the reactor
container should be added to the base container and mixed, until a homogeneous
mix is obtained.
CONTROL.
- To acquire the specified requirements, follow the Inspection and Test Plan (ITP) in this method statement that will serve as a guideline for the Construction Team and QA/QC Team in monitoring, inspection, and testing.
- A checklist for this activity will be used by the Construction Team to identify each point to be inspected at every stage of the activity.
- The QA/QC Representative will verify the compliance and completeness of the work by inspecting it and reviewing the same checklist.
