PREAMBLE
During the Quality Control Review Meeting on 03.08.2007 the

Chairperson and Managing Director/ TSTransco has instructed to prepare the
quality assurance plan for erection of 132 KV and 220 KV lines & substations
for implementing in TSTransco.
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 TSTransco.

The following issues were deliberated to ensure quality during
execution of works:
1. Check Survey
i) Verification of line deviation angle and bisection for proper location
of towers.
ii) Verification 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 of displacement
of angle point peg.
v) At peg marks GPS marking should be done. This ensures correct
position of peg even if it is removed, as the longitudes and latitudes
are 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, power
line crossings and special locations limiting to the 75 locations as
provided in the contract.
iii) Instead of identify 75 locations, it is better to perform soil
investigation for every KM of soil. Investigation is done by way of
ERM 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 the ground as per pit marking
drawing for standard type of foundation and note levels of the
center of each leg pit w.r.t center peg of the tower.
ii) Assess volume of bench cutting or use of hill side extension
revetment if required and take approval of the Superintending
Engineer /Chief Engineer.
4. Foundation Classification
i) One of the foundation pit to be used as a trial pit and excavated as
per normal soil dry type foundation.
ii) Observe following for classification
- Type of cultivation surrounding tower and whether
encasement of stub required due to surface water.
- Type of strata and depth of each layer.
- Water table/level.
- Maximum water table in the near by village well.
iii) Check and record soil classification and foundation classification

as per relevant clauses of the agreement and excavate pit as per
approved drawing for the type of foundation classification. (Extract
of Technical Specification is enclosed).

4.1 CLASSIFICATION OF FOUNDATIONS:

Classification of soil shall be made according to IS : 200 (Part I) 1974 for footing cast in
open pits. The foundation designs for various types of Foundations as given below shall
be adopted in the construction of all 132 kV & 220 kV Transmission Lines and shall be
based on the following instruction. The Foundation Drawings as finalized by the Civil
Engineering Wing for various soil conditions suitable for different Types of Towers
being deployed in the construction shall be followed by all field officers strictly.
Sl.No. Soil at the Location of Tower Classification of

foundation to be
adopted.
1. Where normal dry cohesive or non-cohesive soils are met. Dry
2(a). Where sub-soil water is met at 1.50 meters or more below the ground level Wet
in normal soil
(b) Where surface water could stand for long period with water penetration
not exceeding 1.0 m below ground level (e.g. Paddy fields, Sugarcane
fields)
3(a). Where sub-soil water is encountered between 0.75 meter and 1.50 meters Partially Submerged /
depth below ground level. Partially Black
(b) Where top layer of Black Cotton soil extends up to 50% of the depth with Cotton
normal soil thereafter
Note – 1 Where soil is clayey type, not necessarily black in colour, which shrinks when dry, swells when
wet.
4(a) Where sub-soil water Table is within 0.75 m depth from ground level. Fully Submerged –
(b) Where top layer of Black Cotton soil exceeds 50% and extends up to full Black Cotton
depth or is followed by normal soil.
(c) Where top layer is normal soil up to 50% of the depth but the lower layer
is a Black Cotton soil
Note – 2 In case of items 4(a), (b) & (c) above, the concerned Superintending Engineer (Civil) shall
personally inspect and certify on soil classification and shall not delegate this responsibility to any
sub-ordinate officers.
5(a) Where decomposed or fissured rock, hard gravel, kanker, limestone, Fissured / soft rock
laterite or any other soil of similar nature is met.
(b) Where top layer of normal dry soil extends up to 85% of the depth
followed by fissured rock without presence of water.
6(a) Where Hard rock is encountered at 1.5 m or less below ground level. Hard Rock
(b) Where Hard rock is encountered form 1.5 m to 2.5 m below Ground Level
though Top layer is of normal soil
(c) Where chiseling, drilling and blasting is required for excavation.
Note – 3 While classifying foundation of Wet, Partially Submerged / Partially Black Cotton, Fully
Submerged / Black Cotton foundations mentioned above, the worst conditions may be considered
and not necessarily the conditions prevailing at the time of inspection. For instance, there are areas
where sub-soil water rises when canal water is let-out in the field raising sub-soil water to a
considerable degree. Similarly the effect of monsoon or when the nearby reservoirs are full should
be considered and not the conditions prevailing in open season or summer when work is carried
out normally. In all such cases, the Chief Engineer (Civil) shall personally inspect and certify the
requirement of higher classification on case to case basis.
4
Note – 4 For critical locations of cut-point / Angle Towers, the classification of Tower
Foundations may be at next higher type for ensuring safety of the transmission
line as likely to be subjected to variable forces from time to time on account of
change in season and climatic conditions. This shall be decided by the
concerned Superintending Engineer (Civil) on case to case basis on personal
inspection.
Note – 5 In case of highly collapsible & loose soils and river crossings, special design for
foundations are to be made by Civil Engineering Wing for adoption on case to
case basis.
Note –6 At locations subjected to water logging, particularly in paddy fields, ponds,
marshy areas, etc., the chimney of all stubs to be raised to 600 mm over the
normal chimney being adopted in other cases. This shall be done after complete
erection of towers as a separate item for identified locations.
In addition to the above, depending on the site conditions more varieties of

foundations may be introduced suitable for intermediate conditions under the
above classifications to effect more economy.
5. Form Work
Verify form work dimensions, rigidity, adequacy of tightness to prevent

loss of cement water from concrete, ensure form surfaces in contact with
concrete wetted and sprayed with fine sand/treated with black oil or
waste oil/mould releasing agent every time before use.
6. Stub setting and Stub setting template
i) Recheck the depth of the pits w.r.t center peg level and pit
dimensions as per approved foundation classification.
ii) Check under cutting as per approved drawing.
iii) Position fully assembled and bolt tightened stub setting template
with supporting jacks placed on firm ground and level the
template.
iv) Check placing a green concrete block of thickness equal to the
clearance between the stub end and concrete to mitigate settling of
template.
v) Check height of template above the center peg level.
7. Reinforcement
i) Check reinforcement dimensions as per bar bending schedule. Tie

reinforcement at alternative crossing points with suitable binding
wire.
ii) Verify using chair and gitties to ensure proper spacing in two
layers reinforcement and minimum cover of 50 mm on the bars
respectively.
iii) Before commencement of concreting ensure sufficient quantity of
chairs and gitties are fabricated and made available at stores for
use at locations.
5
8. Concrete Mixing
i) Ensure using coarse aggregate (metal) and fine aggregate (sand) as

per IS-383.
ii) Check coarse aggregate for flakiness, 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 of
concrete.
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 bottom

of the excavated pit before placing reinforcement.
ii) Use pointing/poking rod and vibrator for compaction of concrete
ensuring vibrator head does not come in contact with steel,
hardened concrete etc.,
10. Stripping of Form Work
Ensure stripping formwork after about 24 hrs and check for any damage,
honey combing and do necessary rectification.
11. Back Filling
i) Ensure back filling on foundation in layers and ensure proper

consolidation.
ii) Ensure all top soils to be placed at the surface in case of towers
located on cultivated land.
iii) Excess earth available over and above ground level (after
consolidation) should be transported away from the site.
12. Curing
Ensure proper curing by keeping adequate quantity of water and storing

arrangement available at 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 minimum tower footing resistance.
14. Formats & QAP is revised with reference to the discussions and the
revised formats & QAP are enclosed herewith. The Superintending
Engineers should get the formats printed and bounded as registers and
to ensure, they are distributed to Section Officer level.
