6. CONSTRUCTION STATEMENT METHOD
6.1. Construction of Concrete Foundation
6.1.1 Staking of Tower Location
Staking of tower location is to identify the exact location of towers on the field
and to mark the location for construction. The work will be performed after checking
of line route and spotting of towers on the plan and Profile drawings. Three stakes will
be provided on the center line of the transmission line. One stake at the station of
the proposed tower location and the other two reference stakes will be located on
the center line of transmission line 10 meters ahead and behind center stake. Top of
the center stake shall be driven to an elevation to be known as working point from
which the line and grade of the tower will be established. Adequate protection for
these stakes will be provided to prevent disturbance during right-of-way clearing ,
site preparation, and tower construction. The working procedure can be detail as
followings:
9

T-LR-A-230-WP -004-A1

6.1.1.1 Staking of suspension towers, which are in straight line of the line route.
Starting with finding the center point of the tower. Make sure that the
center of the tower is in the straight line of the line route. After that
identify the diagonal line and then locate each of the 4 foundations.
6.1.1.2 Staking of tension towers, which is an angle tower. First of all, all
references generated during the line route survey have to be checked.
The center point of the tower is located according to distance specified
on the Plan and Profile drawing. The deviation angle of the back line
and forward line is divided in half. After that, diagonal line is identified
and also the location of the 4 foundations.
6.1.2 Excavation
Excavation of foundation includes leveling of bottom of the pit and work
preparation prior of casting of concrete foundations. Excavated materials will be
stocked nearby and will be used to backfill the pit after the work is completed. The
surrounding areas will be return to the original condition as much as possible.
Excavation of pit will be adequate and large enough to accommodate
activities in the construction of concrete foundation. Except for the foundation that
used existing ground as formwork. Depth of the pit will be as specified in the drawing
of the foundation used.
10

T-LR-A-230-WP -004-A1

Concrete foundation will be constructed on an undisturbed material.
Concrete will be casted right after the pit is excavated. Slope of the pit will be
protected and maintained. Wooden wall or steel sheet piles will be used in case that
the side slope cannot be held. The side slope protection devices will be removed
prior of backfilling. Bottom of the pit will be cleaned, free of lost soil.
Incase of over excavation, the bottom pit will be filled with compacted sand
or lean concrete. Water pump will be provided to drain all excess water inside the
pit.
During excavation, water level will be recorded and compared with the
foundation list. Bearing capacity of soil may change if the level of underground
water level is changed and type of foundation may have to be changed to suit the
actual soil condition.
6.1.3 Rock Blasting
Rock blasting will be applied when large volume of rock has to be removed
or excavated. There are many type of rocks around depend on the
geological location and origin of the rock and how the rock was formed, but
in this procedure we will focus on rock found in the beginning of the new 230
kV. Transmission line near the dam site.
The rock blasting procedure may be separated into 2 categories,
depend on the propose of the work.
11

T-LR-A-230-WP -004-A1

1. To remove pointed sharp rock and to flatten top of area of rock
surface. Mainly to make access way or working area.
2. To excavate down into rock to make tower foundation.
The procedure in rock blasting for both categories are similar, except for
the drilling pattern of the holes and detonating sequence of the explosive,
which will be detailed later on.
6.1.3.1 Equipment and Materials
• Air Compressor.
• Rock Drill.
• Air Hose.
• Explosive (RJ).
• Ammonium Nitrate (ANFO).
• Detonator.
• Electric Wire.
• Control Switch.
• Protection Blanket (Sheet Plate, Sand Bag, Sag, Wooden Cover, etc.).
• Ear Plug.

12

T-LR-A-230-WP -004-A1

6.1.3.3 Blasting Procedure
i. Drill 32 mm. diameter holes at 1.5 to 2 meters in depth . For
removal of rock peak or flattening of rock surface, the holes will
be drilled into the rock at difference locations depend on size of
the rock. The numbers of holes will be determined by the size of
broken rock desired after blasting. On average, the holes will be
between 0.6 m. to 1 m. apart. For excavation into rock surface to
make void for concrete foundation, the holes will be drilled
vertically into the rock surface as shown on the following pattern.
The pattern of the holes will be arranged in ring shapes one
around the other. The first hole will be drilled at the center of the
desired shape. It will be designated as number 0. Holes on the
second ring (Ring number 1) will be about 0.6 meter from the first
hole. Holes on the third ring (Ring number 2) will be about 0.6 meter
from the second ring, and so on until the entire desired area is
coverd.
ii. Install explosive (RJ) into bottom of the drilled hole. Quantity of
explosive to be used depends on volume of rock to be
removed. On average, 100 grams to 500 grams of explosive is
needed to remove 1 cubic meter of rock, in case of blasting of
rock peak. For rock excavation, the quantity of explosive is
increased by 20% in the holes in the next outer ring.
iii. Install detonator into the hole. The detonator will be wired and
ready to be connected to the control switch.
iv. Fill the hole with Ammonium Nitrate (ANFO) to level of about 0.6
meter above the explosive.
v. Fill the hole with sand or fine or crushed rock.
vi. Cover blasting area with protection blanket, if the fly rocks have
to be subdued.
vii. Connect all of the wires from detonators to control switch.
viii. Check for safety devices. Make sure that all personnel are in safe
places with protection gear on and all sensitive equipments or
facilities are securely protected.
ix. Sound the warning Siren 60 seconds and 10 seconds before
blasting.
x. Detonate the explosive. For removal of rock peak, explosive in
very holes are detonated at the same time. But for the rock
13

T-LR-A-230-WP -004-A1

excavation, the blasting will be done as controlled blasting, where
detonation will be in sequence. The center hole (number 0) will be
detonated first, follow by the holes in the second ring (number 1),
and the third ring (number 2), and so on. The detonation time can
be set at 25, 50, or 75 milliseconds interval depends on size of the
blasting area.
xi. All personnel will be in cover until 5 minutes after the detonation.
xii. Check for unexploded explosive. If there are any unexploded left
in the area, perform the work again from step vii or remove it
from the hole with compressed air.
xiii. Disconnect all blasting equipments such as electric wire and
control switch.
xiv. Remove all protection from equipments and facilities, reopen
passageway and road to public.
xv. Check for damages, if any.
xvi. Record the result.
6.1.3.4 Storage of Explosive Materials
All explosive materials will be treated as dangerous materials and stored
under maximum security. The storage area will be set up as followings:
i. There will be separate storage house for explosive and detonator.
ii. The storage house for explosive will be at least 30 meters away
from the storage house for detonator.
iii. The storage houses will have no window, only one access door
for transportation of the materials.

above.
11.2 Environmental and Social Pre-Construction
Description
Land cover
The Initial Environmental Examination (IEE, ERM May 2014) stated that land cover
type within the project area to be the deciduous forest about 122 ha, Evergreen
forest 1 ha, Bamboo 6 ha, Scrub heath 7 ha, modified habitat (Agricultural
plantation, Old fallow land, Young fallow land, Rice paddy and slash and burn) 247
ha, unclassified 8 ha, water 3 ha, shadow 1 ha, could 4 ha, other land lest than 1 ha
and Rock surface lest than 1 ha
Vegetation condition
According to the IEE, ERM May 2014 the vegetation condition is dived in to four
categories which are based on the NDVI data as bellow:
• The majority of land (94%) is moderate or low condition;
• 5% of the Project area is high condition, and this mostly concentrated
in the northern segment, form south of Houy Nua PPA to the Main Dam;
• Approximately two third of the Project Area is in moderate condition,
and this is event distributed throughout the Project area; and
• Approximately a third of the Project Area is low condition and this is
primarily concentrated in the Paxan region in the south east.
There are no areas of ‘Natural Habitat’ as defined by ADB Safeguard Policy
Statement June 2009, within the ROW.
Land and water use in the area
There is 121.47km length of all transmission line from dam site to Nabong station;
based on the IEE, ERM May 2014 presented that almost 50% of land within the right of
way (ROW) is fallow and 13% is the rice paddies. There is NO ‘Natural Habitat’ along
the entire ROW, only ‘modified’ and ‘degraded’ habitat types. (See Appendix 12.5).
Along the right of way alignment has potential passing the natural watercourse,
creeks, Namngiep River, cart track, pit, dike, swamp, pond, irrigation canal, Nam
Leuk and Namngum River see the figure below. However, the villagers who live in this
area are not using this water sources for their daily consumption. These water
sources are used for agriculture, bathing and washing only.

Proximity to villages
The total villages along the ROW from dam site to Nabong Station have 35 villages,
07 villages are located in Pakngum district of Vientiane Capital, 07 villages are
located in Pakxan district and 21 villages are located in Thaphabat of Bolikhamxay
province (see table below) . All are predominantly ethnically Lao Loum, the majority
groups in Lao PDR. Most households rely mainly on agriculture for their livelihood,
with forest products and fish important secondary sources.
Archaeology
Based on the IEE, NNP1 (November), there is one significant historic site and tourist
attraction located along the transmission line corridor. Wat Prabat Phonsan is
located next to National Road No.13 South, in Ban Prabat Phonsan, Thaphabat
District. Important relics/artefacts at the temple include a model of the footprint of
the Lord Buddha, a giant reclining Buddha, and ancient drum.

An Environmental Management Activity for Concrete Foundation, Erection of Steel
Towers and Stringing work can be referred to in Attached no.12.8.
Sub-plan for Concrete Foundation, Erection of Steel Towers and String of Conductors
– Environment
SP01: Erosion and sediment control
As request during the construction of Concrete Foundation, Erection of
Steel Towers and String of Conductors might occur an ad hoc erosion
control especially the location where it near by the watercourse, creeks
and the river bank.
The control of erosion and sedimentation will be executed by drainage
pipe culverts, side ditches, silt fence, re-vegetation and slope
compaction. The location of potential erosion controls will follow natural
watercourse flow and number of risky points which will be determined by
the actual inspection with owner. The potential location of erosion risky
and water-flow might be requested as shown in the Attached no.12.10.3
Mitigation measure for erosion and sedimentation control of slope will
include:
‐ All topsoil and cleared vegetation will be stockpiled at designated
sites.
‐ Sediment traps will be placed around inlet of culverts to reduce
sediment flow to the river and watercourse.
‐ Medium to large rocks will be placed on the slope surface of pipe
culvert outlet to prevent erosion of the outlets.
42

T-LR-A-230-WP -004-A1

‐ Speed humps will be installed inside of side ditch at 50m intervals to
reduce water flow during heavy rain periods, allowing sediment to
be trapped within the side ditch.
‐ In the case that overflow from side ditches occur the ditch size will
be increased or modified accordingly.
‐ Weekly inspection are conducted as part of the Contractor’s
Environmental, Health and Safety procedures, and these will
include inspections of side ditch and sediment traps.
‐ Any maintenance such as sediment control of Concrete
Foundation, Erection of Steel Towers and String of Conductors will
be at the inspector’s discretion, with frequency of clearing
increasing during heavy rain periods.
‐ Each foundation work topsoil stockpile will be appropriated
disposed at approved site, the topsoil should be shaped and
landscaped into stable landforms;
‐ Final landforms slopes should not exceed 1:2.0 (V:H), it is provided
that sufficient slope stability should be expected considering actual
site condition;
‐ In all cases, access to tower sites will need to use the existing ROW
and access roads. The construction of new temporary road must
have appropriate design to minimize erosion
SP02 Water availability and Pollution Control
During the foundation excavation might occur the water availability and
pollution which it might require to have a necessary control as below:
‐ Open ditches will be designed to allow water to be diverted,
avoiding direct discharge into river and watercourse. By diverting
turbid surface water run-off this will allow for maximum infiltration.
‐ All maintenance of earthwork machinery shall be conducted at
workshops to avoid any storage of hazardous material such as oil
and fuels on site. The use of re-fueling trucks will eliminate the need
for any fuel to be stored on site.
‐ If repairs need to be carried out on site, an oil pan needs to be
used to collect any oil and reduce spillage.
‐ Provide the waste bin, temporary toilet, bathing and washing area
at mobile and temporary camp;
‐ Mobile and temporary camp construction away from watercourse
especially Creek, Stream, and River to avoid pollution of the
environment;
