PREAMBLE

During the Quality Control Review Meeting on 03.08.2007 the

Chairperson and Managing Director/ APTransco has instructed to prepare the

quality assurance plan for erection of 132 KV and 220 KV lines & substations

for implementing in APTransco.

Accordingly, the Quality Assurance Plan is prepared for erection of

132 KV and 220 KV line & substations and approval accorded by technical

committee for implementing in APTransco.

The following issues were deliberated to ensure quality duringe x ecution of works:

1. Check Survey

i) Verication of line deviation angle and bisection for p roper locationof towers.

ii) Verication of meeting statutory clearances.iii) Check spans on either side of the tower location.iv) Mark distances and angles from angle point at 3 conspicuous

places to identify the angle point location in case o f displacementof angle point peg.

v) At peg marks GPS marking should be done. This ensures correctposition of peg e ven if it is rem oved, as t he longitudes a nd latitudesare recorded.

2. Soil Investigation

i) Identify 75 locations for performing SPT.ii) SPT to be performed at all angle points, at locations where soil

strata changes, railway and national/state road crossings, powerline cros sings and special locations limiting to the 75 locations a sprovided in the con tract.

iii) Instead of identify 75 locations, it is better to perform soil investigation for every KM of soil. Investigation is done by way ofERM method, time is saved and soil investigation can be done

without disturbing standing crops.

3. Pit Marking

i) Mark position of all the four pits on t he ground as per pit markingdrawing for standard type of foundation and note levels of thecenter of each leg pit w.r.t center p eg of the tower.

ii) Assess volume of bench cutting or use of hill side extension

revetment if required and take approval of the SuperintendingEngineer /Chief Engineer.

4. Foundation Classication

i) One of the foundation pit to be used as a t rial pit and excavated asper normal soil dry t ype foundation.

ii) Observe following for classication- Type of cultivation surrounding tower and whether

encasement of stub required due to su rface water.- Type of strata and depth of each layer.- Water table/level.- Maximum water table in the near by vi llage well.

iii) Check and record soil classication and foundation classicationas per relevant clauses of the agreement and excavate pit as perapproved drawing for t he type of foundation classication. (Extractof T echnical Specication is en closed

).

58. Concrete Mixing

i) Ensure using coarse aggregate (metal) and ne aggregate (sand) asper IS-383.

ii) Check coarse aggregate for akiness, soft stone and laminar shape.iii) Check cement for approved brand.iv) Ensure proper mixing of concrete as per the guide lines.

v) After mixing and before placing the concrete in the foundation pit,take samples for checking compressive strength and slump test ofconcrete.

vi) Engage ready mix where even possible to enable execute fast work.

9. Placing of Concrete

i) Check providing lean concrete (M 10) base 100 mm thick at bottomof the ex cavated pit before p lacing reinforcement.

ii) Use pointing/poking rod and vibrator for compaction of concreteensuring vibrator head does not come in contact with steel,hardened concrete et c.,

10. Stripping of Form Work

Ensure stripping formwork after about 24 hrs an d check for any damage,honey combing and do necessary rectication.

11. Back Filling

i) Ensure back lling on foundation in layers and ensure properconsolidation.

ii) Ensure all top soils to be placed at the surface in case of towerslocated on cultivated land.

iii) Excess earth available over and above ground level (afterconsolidation) should be transported away from the si te.

12. Curing

Ensure proper curing by keeping adequate quantity of water and storingarrangement available a t site.

13. Earthing of Tower

i) Ensure tower footing resistance not to exceed 10 Ohms.ii) Use pipe earthing or counter poise earthing as per approved

drawings to ensure m inimum tower footing resistance.

14. Formats & QAP is revised with reference to the discussions and therevised formats & QAP are enclosed herewith. The SuperintendingEngineers should get the formats printed and bounded as registers andto en sure, they a re d istributed to Section Officer l evel.

15. All the foundation drawings, and other instructions shall be distributedupto Section Officer level.

Section: GENERAL GUIDELINES FOR IMPLEMENTATION

11 CEMENT

11.1 In case su pply of cement is in the scop e of the con tractor, the sam e sh all be procured from sources approved by APTRANSCO site and got tested at

site on sample basis for specied acceptance tests as specied in thisFQP at a reputed Third Party Lab ap proved by APTRANSCO site.

11.2 The sam ples of cement for site testing shall be taken within three weeksof the delivery and all the tests sh all be commenced within one week ofsampling.

12. REINFORCEMENT STEEL

12.1 In case su pply of reinforcement steel is in the sco pe of the contractor, thesame shall be procured from the main producers i.e., SAIL, TISCO,HSCO or Rashtriya Ispat Nigam or the recollers approved by mainprocedures. The reinforcement steel shall be got tested at site on sample

basis for specied acceptance tests as specied in this FQP at a reputed Third Party Lab approved by APTRANSCO site.

12.2 The result of the testing of cement and reinforcement steel referred to in13.1 and 14.1 above shall be got approved from APTRANSCO site beforecement and reinforcement steel are put to use. However, in exceptionalcases due to exigencies of work. APTRASNCO site may authorize thecontractor to use Cement and Reinforcement Steel even before the testresults are received. However, in all such cases, if the test resultssubsequently received are found to be not complying with the speciedacceptance cri teria, the contractor sh all have to dismantle and recase a ll

such foundations cast with such non-conforming materials at his owncost. Conrmation to this effect shall be obtained from the contractor bythe Project authorities b eforehand in all such cases.

13. All the testing and measuring equipments used by the contractor fortesting are required to be calibrated. A copy of valid calibration reportshall be retained by APTRANSCO as records.

14. Calibration certicates to be got veried from APTRANSCO for tools andplants an d testing equipment before t heir use.
