Non Plant BuildingsSafety General

1 Refer to Chapter 3, MS 12 & 13, Chapter 4, MS1, Chapter 6, for general provisions on safety discipline in addition to those included with various method statements on this Chapter

2 Relevant point should be extracted from description in line to requirements on relevant activities

3 It is to be noted that safety standards vary from organization to organization, company to company & client to client

4 Just consideration of economy on project cannot exclusively, be a criterion to avoid or reduce safety measures

5 A minimum level of safety measures installations should be made a ‘must’ for a site supervise to ensure that workforce ‘must’ work safely

6 It is preferable to work with acceptable level of safety rather than loosening lives of workers

Safety1 Prior to commencement of an activity, workforce shall receive a STARRT Card/Toolbox

Talk relevant to operation concerned on Project Site safety requirements. Necessary measures shall be applied to a process involving a safety risk.

Safety Supervision 1 A competent officer shall visit area daily to assess safety measures being adopted. All

snag observed during visit, shall be notified to supervisor present, who immediately, would act to bring safety measures to an acceptable standard

Materials1 Cement, washed sand, bonding agent, water

Method (Laying floor screed by SEMI DRY method)

1 All rooms shall be laid in full area in one go.2 Proposed designated area shall be laid according to location of joints as shown on shop

drawing separately.3 Either Scabbling of concrete surface shall be carried out if so required, for proper

bonding with hardened surface or etching surface, if so agreed by Company.4 (Etching requires 10% concentration hydrochloric acid to be mixed with water for

forceful application on RCC or concrete surface followed by immediate washing out by water, which process roughens concrete surfaces.

5 Border of portions to be applied with etching, are paper taped for adjoining protection from acid scouring effect). Benefit of etching is that it avoids scabbling or hacking.

6 Concrete surface shall be cleared of all loose particles and cleaned, with using hard wire brush to ensure achievement of sufficient roughness to receive screed.

7 Levels up to which, floor screed is to be laid, shall be profiled by using Mechanical leveling points with steel pipes to maintain levels, so that complete compartment is given a proper level profile.

8 Cleaned area shall be soaked with water for 24 hours prior to application of screed.



9 Contractor QC & Company inspection shall be conducted for examination pertaining to preparatory works for ‘ready to pour’ compartments.

Application 1 After preparation for an area or alternate bays or strips of 1500 mm width or as sized on,

site is made up with all levels, cleaned, duly soaked in water for 24 hours and ready for pouring.

2 Prepared surface shall be spread with cement slurry ratio 1:1 (1 part cement and 1 part sand) mixed with mix quality water.

3 Mortar for screed shall be mixed semi dry by a mechanical mixer with allowed only sufficient water added to give just a crumbly consistency, which retains its shape, when squeezed by hand permitting no fluidity.

One layer application with 1:2.5 cement– screened sand mortar1 Mix shall be placed in one layer progressively to a thickness approximately 10 mm

greater than that actually required, thoroughly compacted by tamping and drawn off to marked level with a screed board.

2 In case, thickness of screed is more than 75mm, 8 mm T reinforcing bars shall be placed in both directions @ 300 mm c/c to protect cracks formation.

3 After compacting layer of mortar, surface shall be finished by a steel power float to achieve a smooth level surface ready to receive vinyl tiles or epoxy painting/coating floor finishes and then covered with polythene membrane for immediate curing. Power float shall be applied only, when finished layer is set & dried enough to allow equipment operation.

4 Adequate illumination shall be arranged for application of power float & other steel trowel finish activities.

5 Finished surface shall be permanently cured by adding water soaked hessian, after a few hours of finishing and recovered with polythene sheet.

6 Surface shall be kept wet for a period of 3 days and then protected with hard boards spread over till floor finishes are applied over surface.

7 No traffic shall be allowed over finished surface.8 Throughout above operations, Contractor QC visual inspection shall be conducted.9 Prior to full scale commencement of screed operation, a mockup sample shall be

produced on site in presence of Company representative so that, an agreement pertaining to stated procedures to carry out screed and about Quality could reach.

5. Material1 Approved concrete repair compound

6. Method1 Upon removal of formwork, concrete surface shall be inspected by QA/ QC & Site

Engineer to establish if certain surface defects have occurred.2 Where no surface imperfections have occurred, concrete surface shall be cured according

to relevant procedures included within concrete method statement i.e. application of curing either by spraying curing compound to form a continuous membrane or by continuous application of water.

3 Minor defects as described in A – D below shall be repaired as soon as, practical. 4 More significant defects as described in E – H shall be subject to joint

inspection/agreement between Company and Contractor.

A. Pin holes/blow holes1 Where small defects to concrete surface have occurred, such as pin holes or holes smaller

than 3mm in diameter or depth, surface shall be repaired using Nitomortar FC or equivalent other, with compatible bonding agent Nitobond AR. This surface repair shall be conducted as soon as, formwork is removed whilst concrete is still green.

2 Repair shall then be left for curing in for 24 hours using cover of polythene sheet on repaired surface. Prior to polythene sheet covering, Nitobond AR shall be applied by brush on repaired surface

B. Sand runs/scouring1 Water movement inside shutter can result in a streaky appearance with a loose sandy

finish.2 Contractor QA/QC & Site Engineer shall inspect struck surface & if such runs are

observed, discuss with Company, who may inspect visually & finalize for Nitomortar FC or equivalent application.

3 All loose material shall be removed by stiff brushing and then repaired as indicated in ‘A’ above.

cracks 0.5mm wide & 3 mm deep. 2 Contractor QA/QC with Site Engineer shall inspect surface & if such cracks are

observed, discuss with Company engineer, who may inspect visually & finalize for repair application

F. Major voids (Typically Deeper than 5cm)1 Contractor QA/QC with Site Engineer shall inspect surface & if such honeycombing

observed, discuss with Company, who may inspect visually & finalize for repair application

2 This repair shall consist of chipping affected area to remove all laitance and voids. 3 Where reinforcement is exposed in a void, surrounding concrete shall be chipped away to

provide adequate space to place fresh concrete around reinforcement. (Note - a distance of one and a half times stone size shall be allowed around all exposed reinforcement).

4 Formwork shall be provided to retain fresh concrete repair. 5 Chipped repair area shall be soaked and then be primed with a bonding agent such as

Nitobond AR. 6 Bonding agent shall not be allowed to dry.



7 Repair area shall be formed to retain concrete, such as letter box type formwork for vertical surface.

8 Fresh concrete of same grade as surrounding concrete shall be used to repair defect. 9 This repair shall be carried out, while concreting some other elements of same grade of

concrete as repair element. 10 Repair shall be water cured along with parent concrete. Surface finishes to repair shall be

of same standard as surrounding concrete.

G. Plastic settlement cracks1 Cracking caused by settlement of concrete can result in a series of cracks, which mirror

reinforcement pattern in horizontal surfaces or appear to arch on vertical surfaces.2 Contractor QA/QC with Site Engineer shall inspect surface & if such cracks observed,

discuss with Company engineer, who may inspect visually & finalize for repair application

3 All such cracks shall be chased out to a depth of 10-15mm and filled with an epoxy mortar, such as Renderoc TG.

H. Porous/spongy surface1 Contractor QA/QC with Site Engineer shall inspect surface & if such cracks observed,

discuss with Company engineer, who may inspect visually & finalize for repair application

2 All affected surfaces shall be ground back to good concrete usually only 2-3mm below surface. Surface shall then be reinstated using Nitomortar as indicated in ‘A’ above.

3 All repairs noted above shall be recorded on post pour inspection form. 4 It may not be necessary to raise a nonconformance report provided repairs are carried out,
