Safety General1 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

cleaned and filled to normal maximum level to meet requirement of clause 9.2 BS 8007 : 1987 Testing of structures i.e. up to 11.5 m, which should take 14 days and then be retained for a stabilizing, absorption & autogenous healing period of 7 days for a maximum design crack width of 0.1 mm.

2 Test period starts now for 7 days and drop in level recording be made every 24 hours during this 7 days period.



3 Total permissible drop in level allowing evaporation etc. should not be more than 1/500 of average water depth of full tank, which limits to 10 mm or another specified or calculated amount.

4 Having test been successful, backfill shall be carried out5 Foregoing explanation provides application of concrete protection coating prior to

water tightness testing but, preferably, coating should be applied post successful water tightness testing.

6 Onsite, where this project was carried out, application of coating was made prior to testing.

7 Factually, on projects, decision depends on all team members including engineer & consultants

Second phase Testing1 Tank shall be further filled up to 13 m level i.e. another 7 days should be allowed2 Stabilization period Another for 7 days (for absorption and autogenous healing)3 Test period Another 7 days (level drop recording at an interval of 24 hours)

Evaporation1 Since, evaporation loss is required to be included for this test as it is to be tested in

open/exposed to sky but, there is no formula applicable to such testing condition.2 Loss of evaporation shall be monitored in resemblance only by keeping a water

filled tray on surface of water during test by noting original level when filled3 During testing & recording test observations, observations form tray would also, be

recorded for incorporating into main observations4 Though, size of basin is much more than that of monitoring tray yet, an idea about

evaporation would assist in calculations.

defective floor screeds, so as to provide a durable and serviceable leveling layer for floor covering to be placed above/on it.






In addition, specifically to this statement1 Safety Officer shall monitor relevant activities, advising and implementing all safety

procedures.2 Respecting all very significant activities involving major quantities, all risks analysis

posed by personnel or by equipment shall be conducted & work safety planned accordingly keeping it intact.

3 Area to be worked in shall be closed for general movement, except those involved with working there and be opened only, when work has properly been completed.

Safety Supervision1 A competent inspector shall visit included area daily to assess safety measures adopted.2 Snag observed during visit shall be notified to supervisor present, who immediately,


Responsibilities1 All inspection and repair work related to concrete floor screeds shall be carried out under

sole direction of a dedicated Site Engineer (SE), who should have full authority and responsibility for ensuring that works are affected in accordance/complying with this Method Statement.

Procedure1 Repair activities shall be restricted to a limited number of rooms at one time, while access

to rooms restricted during repair. 2 Before commencing repair activity including preparation, SE shall ensure that previously

completed works are suitably protected from damage and dust using a combination of polythene sheeting and by ply boarding as appropriate.

3 Before commencing repairs in a room, SE shall agree scope of repairs to be undertaken with Site Quality Manager for agreed repair marked on floor.

4 Scope shall be recorded on a sketch, which should identify type of repair to be used and approximate area involved with repair.

5 Repairs shall be selected from following working criteria:

Repair Type A – Removal and Reinstatement with Cement Screed.1 This repair should be adopted, where existing screed has completely de bonded and

cracked, leaving loose isolated sections of screed.



Repair Type B – Repair with Epoxy Mortar1 This repair should be adopted, where developed significant isolated cracks in screed. 2 It is not intended to repair minor hairline cracks by this method or construction joints

between adjacent panels of screed, unless those have become otherwise damaged.

Repair Type C – Repair with Resin Injection1 This repair should be adopted, where screed appears to be de bonded and cracked or

lifting, but is otherwise intact. 2 This may be carried out in conjunction with repair Type B above. 3 It is not necessary to use resin injection on hollow sounding areas, where is

seen/observed no other sign of failure.

Repair Type D – Surface Epoxy Coating1 This repair shall be applied as a final protective coating to all repaired areas. 2 Shall be used for sealing unrepaired hairline cracking3 Shall also, ensure an overall uniform appearance of repaired areas.

Repairs shall be carried out as follows:Repair Type A: Removal and reinstatement with Cement Screed

1 Affected area shall be saw cut to full depth of screed to be removed and affected section removed carefully, so as to cause minimum disruption to adjacent areas.

2 Removed area shall be fully cleaned of all dust and debris and all loose material removed. 3 Cleared area shall be thoroughly soaked (not just dampened) for at least one hour before

reinstatement/repairs. 4 Immediately, before placing replacement screed, remove all surplus water (substrate

should still be wet) and apply one coat of NITOBOND PVA bonding agent to all surfaces, horizontal and vertical.

5 Place, compact replacement screed material, trowel and immediately, cover with polythene sheeting placed flat against/over surface.

6 Remove polythene sheet after 4 hours and replace with wet hessian to be recovered with polythene sheeting.

7 Ensure that further water is added to hessian at least twice daily for a minimum of three days.

8 Hessian to be kept damp whole time, until curing activity is completed9 Ensure that nobody walks on repair for minimum three days.10 If unavoidable, lay ply sheet over repair ensuring it remains in place.

Repair Type B – Repair with Epoxy Mortar1 Using a hammer and chisel, carefully chase a ‘V’ notch along length of crack and along

edge of all loosened area. 2 This should typically be 5mm from edge of crack and 5mm deep. 3 Physically remove all loose material and clean using a wire brush or similar other device. 4 Remove all dust and debris using a brush and/or vacuum cleaner.5 Mix repair material NITOMORTAR FC-B (or FC) in accordance with manufacturers

recommendations and firmly press repair mortar into place, using a steel trowel.



6 Finish material flush with surrounding concrete. It may be necessary to apply a second leveling coat, if material settles.

7 Ensure that repair area is not walked on for 24 hours by protection.

Repair Type C – Repair with Resin Injection1 Drill three 10mm holes in area to be repaired to a depth of approximately 35mm

representing interface between two screed layers.2 This can be determined by change in sound of drill.3 Fix an injection nipple to drilled holes using an epoxy mortar e.g NitoMortar FC-B, seal

using a trowel & allow setting for eight hours.4 Mix repair resin NITOFILL EPLV in accordance with manufacturers recommendations

and insert into injection gun.5 Commence filling central nipple and continue, until resin is observed at outer nipples. 6 If necessary, continue filling outer nipples. 7 Note that material usage rate should be approximately 1litre per 1m2. 8 Do not attempt to place more than this or floor could lift further.9 Leave for 6 hours then remove nipples and fixing mortar.10 Make surface good using epoxy mortar (Nitomortar FC-B or FC).

Repair Type D – Surface Epoxy Coating1 Ensure all repairs have been completed and allowed to cure (24 hours for epoxy repair –

5 days for cement screed repair).2 Brush surface thoroughly to remove all dust and debris, ensuring that surface is not wet

or damp.3 Mix material NITOFLOR FC140 in accordance with manufacturer’s instructions. 4 Firstly apply a stripe coat to certain untreated minor cracks taking care to work paint into

crack.5 Starting at furthest corner, apply a single coat to entire surface, using a brush or roller,

ensuring that material fully coats surface, but without ponding.6 Ensure that surface is not walked on for 24 hours.

by personnel or by equipment shall be conducted & pour safety planned accordingly keeping it intact.

Safety Supervision1 A competent inspector shall visit included area daily to assess safety measures adopted. 2 Snag observed during visit shall be notified to supervisor present, who immediately,


Method (sketch # 58/59/31-55etc. all meant for concrete works indicatively)



1 Structure that is scheduled to be concreted shall be inspected and approved as acceptable for concrete pouring by both Civil Contractor and EPC Contractor/Engineer.

2 Permission to place concrete shall be authorized by EPC Contractor3 Concrete Foreman shall ensure that all adequate equipment resources including standby,

(vibrating pokers, compressors, hoses, steel fixer, carpenter, stop ends, water etc), are available at location of concrete placement.

4 When major massive concrete pour is scheduled, a pouring plan shall be issued by project engineer or construction manager defining various sequences, which plan should be available with concrete foreman for implementation.

5 This plan shall help easy & successful pouring giving location of concrete pump, transit mixers arriving frequency, location of transit mixers during site sample testing, sequences of concrete either in layers in full or in stepping, so as to avoid formation of cold joints, duration of pours, strength respecting all classes of workers, curing arrangements, emergency solutions & other technicalities to be implemented such as, temperature controls & monitoring thermal gradients etc.

6 When site laboratory concrete technician has approved concrete delivery, concrete placement activity can commence.

7 Refer to Method statement, Testing of Fresh Concrete for further details.8 Concrete shall be discharged by one of two methods. 9 For pours greater than two cubic meters in volume, concrete shall be discharged through

a concrete pump or a mobile crane may be used. 10 For pours less than two cubic meters, concrete can be discharged direct from truck mixer

to location using a direct site fabricated chute, after concrete is delivered to site location chute from transit mixer chute or a mobile crane may be used.

11 Regardless of method of discharge, no concrete shall be dropped from a height greater than two meters or in a manner that causes segregation of aggregates.

12 Immediately, prior to placement activities commence, reinforcement within concrete pour shall be sprayed with clean water, which would prevent concrete from adverse impact of flash setting during high temperature environment.

13 Placement of fresh concrete within shutters/forms shall be conducted in a logical sequence, which sequence shall be agreed prior to commencing pour.

14 Concrete shall be placed at locations that do not exceed 1.5 meters from final location of concrete.

15 Maximum concrete layer thickness of 450 mm shall be observed, so that nozzle of pocker/vibrator interlocks lower poured layer, while vibrating current concrete layer.

16 Fresh concrete shall be compacted with pokers of sufficient size and number.17 Oscillation of vibrator/pocker in no case, shall be less that 10000 per minute but, shall be

considered better, when it is more than 10000 oscillations. 18 Compaction of fresh concrete shall commence, when placement of concrete quantity is

adequate, so that uncontrolled segregation does not occur. 19 Concrete shall be placed in a sequence that ensures that cold joints are eliminated as

explained in foregoing. 20 Each subsequent layer of concrete shall be adequately, compacted into concrete layer

below as explained in foregoing.



21 Where en cast plates, holding down bolts or some other critical embedded items are included within pour, surveyor shall check locations and elevation of all such items, when concrete placement has not been completed.

22 All such embedment or inserts shall be inspected during pre pour approval inspections. 23 Records respecting pre & post pour of all such inserts shall be made for references to

verify locations confirmed within permissible limits of tolerance.24 Immediately, after laid concrete finishing has been completed, it shall be covered with

white polythene sheeting ensuring that edges are sealed to prevent circulation of air.25 Upon adequate setting of concrete, white polythene sheeting shall be removed

temporarily. 26 Hessian cloth, which has been soaked in water, shall be placed over set concrete. 27 White polythene sheeting shall be replaced and sealed at edges immediately. 28 Hessian cloth shall be kept moist for a period of 14 days or as specified within

specifications.29 Immediately after laid concrete is ready to receive curing compound, it may also, be

sprayed if permissible by specifications. 30 Such provision shall prevent hair crack formation that is a result of shrinkage of concrete.31 In that case, immediate cover by white polythene sheet shall not be required but, later on

concrete would be covered as such, for continuous curing for defined number of days.32 When shuttering is removed from an element, exposed concrete surface shall be

inspected. 33 Where a defect is observed, defect shall be classified as either minor or major. 34 A minor defect is one, which does not impair strength of structure or is less than or

around 10mm by 10mm size only, which defect should be repaired using a patching mortar.

35 A major defect shall be brought to attention of QA department for investigation & resolution.

36 A major defect shall be other surface defect that is larger than 10mm by 10mm in size. 37 Method for repair of such defects shall be discussed and agreed with Engineer/EPC

Contractor.38 Repairs to concrete surfaces shall be cured according to meeting requirement for fresh

concrete.

MethodPreparation

1 Substrata shall be clean, sound, free from loose material and contamination, such as plaster, oil and grease

2 Excessive laitance shall be removed by either light scabbling/hacking or application of acid etching followed by washing and debris removed using vacuum cleaner

3 (acid etching requires use of 10% concentration hydrochloric acid to be mixed with water for diluting it, followed by applying that diluted solution on concrete surfaces, which should have already been prepared, bound by paper tape. Immediately, after few minutes of application of acid solution, surface is trashed with clean water without any further, damaging concrete surface)

4 (hacking/scabbling is a process to apply hammering drill or chipping equipment on all areas of concrete surface that successfully, removes laitance from its surface, followed by cleaning hacked surfaces)

5 Acid aching is very fast to remove laitance from surface, while hacking/scabbling consumes considerable time & efforts

A) Blinding Concrete & Protective Membrane.1 Shear key shall be excavated to correct line and level. 2 A suitable site fabricated formwork system shall be adopted for this element. 3 Using traditional plywood with timber batten construction formwork, shear key shall be

formed. 4 This section of construction shall include outside toe blinding plus, required 300mm

membrane lap area.5 A further one metre section of blinding to inside of shear key shall provide level for

internal blinding slabs. 6 Finish to all these blinding for below slabs shall be carried out in accordance with

membrane manufacturers requirements. 7 This includes chamfers, surface being smooth without unevenness & no protrusion that

may require grinding etc. 8 As work progresses, reservoir/basin internal blinding for below slabs shall be cast to

correct level, in bay sizes that do not conflict with base slab construction joints layout.9 When higher level area has been completed, blinding system shall continue to lower

areas.10 In conjunction with these activities, a dewatering system shall be incorporated, that

should remove water ingress from working faces. (if so required)11 Where water has been allowed to stand, all soft areas shall be excavated and removed

from site. 12 A suitable drainage system at low level also, in continuation of higer level, shall be

provided.13 Procedure of constructing shear key to these lower areas and blinding layer, shall be as

previously described.14 Water curing of blinding concrete shall be conducted for 24 hours.15 Work of protection membrane shall be effected by approved applicator/application team,

according to manufacturer’s instructions/details, commencing with application of primer followed with self adhesive membrane being laid as appropriate.

16 Vendor or his approved site representative shall monitor application of membrane system.

17 Concrete protection or waterproofing membrane work may also, be carried out by site personnel after, involved personnel, have been imparted training by occupational demonstration on site by vendor’s specialist under instruction.

B) Base Slabs1 Reinforcement to floor slab sections shall be assembled carefully to avoid damage to

membrane. 2 Waterstop requirement in line to design profile shall be fabricated and installed according

to IFC drawings/jointing fabrication/fusion welding complying to manufacturers details.3 Formwork to base/floor slab sections shall be constructed/fabricated from traditional

marine plywood 18/20 mm thick and soft wooden battens 50x75mm ti 75x75mm 4 m long.

4 A sequence for construction of these base/floor slab panels shall be discussed and agreed between/among by EPC Contractor/Engineer/Civil Contractor.



5 Cathodic protection non critical component items shall be installed and continuity tested details of which tests, shall be recorded.

6 Prior to placement of concrete to a base/floor slab section, site engineer and Civil Contractor QC inspector, shall inspect section for designs & specification compliance, meeting in line to all drawing requirements.

7 Errors shall be rectified if pointed out by quality engineer during site examination. 8 Engineer/EPC Contractor QC shall be requested for inspection respecting works prepared

for this particular section of structure.9 Upon approval to place/pour concrete from EPC Contractor/Engineer, structural concrete

shall be ordered to be procured & placed accordingly meeting procedures of concrete placement in case of involved structural member/item.

10 Curing of slab section shall be carried out according to specification & approved method.11 Formwork shall be removed after specified period has been over. 12 All surface defects shall be inspected between Civil Contractor/EPC Contractor QC

inspectors/Engineer, who may agree on correct repair procedure to be applied for remedy. 13 Curing shall continue to be in line to defined requirements without any lapse.14 Foregoing sequence shall continue for working each base/floor slab section, until all slabs

have been poured similarly. 15 Where specific joint details between base/floor slab sections are shown on IFC drawings,

those details shall be included on, while carrying out preparatory works.16 Where base section occurs on a slope, various sections shall be fixed and vibrated in

careful controlled operation using opening on top formwork of slope, which portion should be used for pouring concrete as well as, vibrating through.

17 Finishing to correct lines & levels shall be conducted using an aluminum straight edge.

C) Walls1 Wall pour sections shall be constructed per IFC drawing details, which indicates location

of movement joints MJs & other joints such as contraction & construction joints CJs. 2 Approved Proprietary formwork system shall be used for sections. Drawings respecting

system shall be available on site duly approved for preparatory works construction3 Giffin Scaffco detail drawings and calculations shall be provided.4 Inside wall formwork shall be erected and braced in compliance to shop drawings. 5 Fixing details for push pull strong backs shall be via a predrilled expansion bolt onto

floor slab section.6 Fabricated Reinforcement shall be erected/placed in according to IFC drawing.7 Waterstop accessories shall be included within wall section at this stage. 8 All waterstop accessories shall be positioned and jointed in strict conformance with

vendor’s instructions.9 Reinforcement and all accessories shall be inspected and approved prior to fixing of

outside formwork closure. 10 Formwork shall be aligned and checked for completeness by work engineer.11 Placement of concrete shall be conducted after EPC Contractor/Engineer approval.12 Pour rate and placement criteria shall be as defined by formwork designer.13 Height of wall shall be poured to criteria indicated by formwork vendor, but each layer

shall not exceed 450 mm maximum to allow effective vibration to poured layer as well as, interlocking previous lower layer



14 Curing of wall section shall be in accordance with specification/approved method.15 Removal of formwork shall be in accordance with specified duration post pouring. 16 Striking of forms shall be done in a safe and controlled sequence, complying with all

safety instructions.17 Green concrete surface shall be inspected for possible defects and repaired as required,

according to approved repair procedure.18 Each wall section shall follow foregoing sequence of construction. 19 Joint details shall be provided in accordance with relevant drawing detail indicated.20 Sequence of wall pours shall be provided by Civil Contractor, to conform to specification
