Notifying QC engineer and issuing the checklist (inspection request for
approval/checklist – Annex A, including all clearances as applicable in a timely manner
when work is ready for inspection.
Accompanying the Engineer’s representative for ongoing inspection and obtain his
approval to proceed with next activity.
The QA/QC Department is responsible for the overall inspection and documentation of
works in compliance with the work procedure and Project Specifications and shall be

6. PROCEDURE
The scope of Work for Tile Installation
1. Materials Handling on Worksite and Storage
Materials shall be received in parts as per site requirements and in standard boxes
and/or packs, pallets etc. Materials shall be stored in the proper way and handled as per
manufacturers’ recommendations if any.
Obtain each color, grade, finish, type, composition, and variety of tiles from the single
source. For grout and setting materials, obtain ingredients of uniform quality from one
manufacturer for each cementitious and admixture component and from one source or
producer.
2. Preliminary in Tiling Works
Work shall comply with all project specifications, rules, regulations, laws, and ordinances
of all authorities having jurisdiction.
Tiles type & color, mortar mix, grout, adhesives, etc., shop drawings and method
statements shall be approved by the consultant prior to commencing any tiling works.
Tiling mockup shall be arranged for final approval at the location designated by the
consultant.
Approved mockup and sample shall be preserved and always readily available at the
site during the entire duration of the work.
Ensure that the MEP clearance is obtained for the particular tile work area.
In wet areas, ensure that the waterproofing is completed and tested for leakage & any
applicable inspections.
Obtain the required safety and health clearance from Safety Department prior to starting
the work.
Restrict the area from foot and wheel traffic prior to and during the tiling, activity to
prevent damages from the finished work.
Inspection requests (checklist Annex A) along with the key plan showing area to be
executed will be raised to Engineers progressively for the tiling/flooring works. All
inspections will be carried out in phases to cover a part of the total work.
3. Worksite Preparation
The areas of the concrete substrate to be tiled are to be brushed clean and dampened
and the finished floor level is to be established.
The mortar for bedding the tiles shall be as shown in the drawing and/or project
specifications.
Setting out shall be done by the surveyor and approved by the consultant.
Engage an experienced installer who has successfully completed tile installations.
4. Tiles Installation and Fixing Procedure
Laying ceramic tiles by Semi-Dry Mix Method. It shall consist of 1 part of cement to 4
parts of sand by volume to form the sand cement mortar, mixed semi-dry in a
mechanical mixer with only sufficient water added to give a crumbly consistency that
retains its shape when squeezed in the hand. To maintain the consistency of mix, the
volume of water added is to be kept same for each batch.
The minimum thickness of bedding with this system of laying is to be 40 mm.
The mix is to be spread to a thickness approximately 10 mm greater than that actually
required for the bed and be thoroughly compacted by tamping and drawing off to the
required level with a screed board which will give even compaction and leveled surface.
Only sufficient mortar is to be mixed and spread as can be covered with tiles before it
has attained its initial set.
A thin layer of the slurry of 1 part cement and 1 part sand, by volume, is to be poured
over the surface of the semi-dry mix bedding and spread with a trowel until it is
approximately 2 mm thick. Approved adhesive to be applied to the tiles to be laid while
the slurry is wet and beaten firmly into position with a wooden beater to ensure a true
surface and contact between the tiles and bedding is complete.
Get approval for tile layout through dry laying before starting tile work if SOP (Start of
Point) is not shown in the drawing. In absence of SOP or approved layout, arrange tiles
so that cut tiles occur at wall lines only and are minimum and where they do occur, they
are as large as possible.
Before tile fixing check that any color, shade variations, and sizes are acceptable.
Lay the tiles side by side or keeping specified gap joint by the use of tile spacers as per
approved pattern as shown in the approved drawings. The tiles must be correctly
positioned at the time they are placed and laid with joints as shown in the approved
drawing.
Carefully removed the tile spacers after the laid tiles are set enough to prevent
difficulties of pulling out the spacers.
Tiles shall be placed firmly according to the level shown in the approved shop drawing.
Tiles shall be placed firmly according to the level shown in the approved shop drawing.
A spirit level should be used to ensure that the tiles are even and level during
installation.
Accurately form intersections and returns. Perform cutting and drilling of tile without
marring visible surfaces. Fit tile closely to electrical outlets, piping, fixtures, and other
penetration, collars or covers.
Tiles are to be laid level or to 1% falls/or as shown in the approved drawings in “wet”
areas, as may be required. Localized variations in level for a nominally flat floor are to be
a maximum of +/- 3 mm under a 3 m straight edge. Particular care is to be taken in “wet”
areas to prevent low spots and the pooling of water.
No soaking is required for fully vitrified tiles or when the adhesive is used.
Install edge strip at the following (1.) At openings without thresholds and similar
discontinuous edges of thin-set tile floors. (2.) Where ceramic tile floors are adjacent to
other flooring materials at the same level. (3.) Where ceramic tile cove base is combined
with other types of flooring and (4.) As shown in the drawing.
Control and expansion joints: Provide control and expansion joints as per approved
Shop Drawings. (1.) Locate control joints as indicated on the approved drawings, but
maximum 4.5 meters on center each direction for interior condition and 3.65 meters
exterior condition. Provide control joints at all perimeters. (2.) The width of joints must
match the width of grout joints. (3.) Seal joints after completion of tile work.
Do not saw-cut tiles control/expansion joints after installation the tiles.
5. Joint Grouting
The grouting mix shall be an approved grout as per submittal ref.: (reference goes here).
Grouting of the joints shall be carried out after 24 hours of the completion of the laying of
the tiles so that the grout will attach itself firmly to the bedding. Care should be taken to
avoid disturbing the tiles during grouting application.
Clean the joint before filling with approved grout.
Apply tile grout to the joint spaces between tiles using a sponge or soft cloth.
6. Cleaning of Finished Work
Remove excess grout, setting bed material, mortar, adhesive with clean clothes or
sponge.
Clean the affected surface area when mortar and adhesive are still in wet form by cotton
waste or any other such material.
When the mortar, grout, and adhesive were dry, remove them with scrapper lightly and
clean with dampening cotton waste or cleaner as specified by the manufacturer.
Clean all tile surfaces and remove cement/tile grout residue from tiles as soon as day’s
work is finished.
7. Protection and Preservation of Finished Work
Remove defective tile and replace with sound tile.
Remove and replace tiles with hollow bearing sound when tapped with steel rod after
installation.
Prohibit traffic until tiles are completely set.
Cover floor area with hard boards, tarpaulins, plastics or gypsum powder to prevent
damages to the installed tiles and preferably area has to be barricaded or restricted for
normal entry or by locking the area.
Repairing of damaged tiling work: If by any reason, any tile is broken or damaged,
remove the tile and replace with sound and similar tile.
