Soil excavation shall be following the construction specification. Topsoil with 20cm average thickness shall be removed and stockpiled along the canal alignment to be completely reused as part of backfilling work at final stage. Suitable spoil from cutting and excavation shall be stockpiled along the canal alignment to be reused as embankment filling work. Detailed proce-dures shall be implemented:

- Formation shall be executed at the excavated embankment position.

- The excavation for intake; inlet and outlet structure shall be according to the ele-

vation and geometrical dimensions according to the design and specification be-

fore next step is done.

- Canal excavation shall be done by using excavator in combination with dump

truck overhauling of the excavated materials. The excavated soil shall be hauled

to the disposal area.

- At the excavated embankment locations, before the construction of concrete

work, the Contractor shall measure, get minor excavation for structure done by

man and thoroughly clean the trench by compression air and clean water.

- Suitable soil excavation shall be used as fill material for canal embankment; top

soil shall be removed and separated from embankment materials (As design) by

excavator.

- After removal of unsuitable soil layer, cleaning the surface, check elevation prior

to filling the soil for embankment. Use tractor to spread the fill soil over the em-

bankment area to a maximum 200mm thickness. The layer shall be compacted

properly to specified density.

- During the construction, if any soft soil area is not shown in the design and it’s

treatment method is not defined. The Contractor shall immediately prepare a re-

port to submit the client’s engineer for the common settlement of the purpose of

works quality control.

- Construction of embankment at locations including both excavation and fill: con-

struction is mainly done by excavator. Firstly, we shall execute construction of

the half excavated and followed by the half-filled. Excavation materials shall be

put onto trucks hauled to disposal area.

2.5. Concrete Work

Preparation

1. Pre pour checks and check sheet (QA system) must be completed prior to the pour, check line and level, check the steel reinforcement against the agreement issued drawings.

2. When all formwork has been checked and that support props are correctly installed, check built and items (for example box-out) then signed any relevant QA document giving permission to pour, not after the pour.

3. Verify that the calculated M25 and correct concrete grade, the slump has been per-formed.

4. Ensure that the correct method of discharging the concrete has been confirmed (pump ordered if required).

5. Check that the concrete delivery vehicles have suitable access and that a banksman will be available during the pour.

6. Check that all persons that will be involved in the work have full personal protective equipment, this should include wellington boots, eye protection, hi-vis vests, gloves and hard hat.

During the Pour

1. Surveying instrument and level must be setup during the pour, checks are to be

made to ensure that the formwork is not moving, or if a problem occurs, adjustment can be carried out.

2. It is vital that fillets are checked to ensure a uniform level on structures. 3. Slump tests are an important check, ensure that this is done. 4. Cubes are to be taken at the correct intervals, and made correctly, to ensure that

cubes are numbered correctly with the pour location and reference number and that they are store properly prior to collection by the testing company.

After the Pour

1. The structure should be checked after the pour, verification of the line and level, and checking walls are plumb.

2. Its good practice to store the coordinates and heights when doing the post pour check to verify position and height against the design, and in addition the as built da-ta will be available (a QA form for post pour check should be available).

3. Any deviations must be recorded and should be reported as a non-conformance.

Curing of Concrete

1. After the initial set of the concrete and when the concrete hard enough to not be damaged by such an action, the exposed concrete surface shall be covered with drenched hessian sacks. These sacks shall be left in position and maintains in a soaked condition for seven days. For formed surfaces the curing shall be applied as described above after the formwork has been removed, or a curing compound shall be applied.

2. Laitance may be removed once the concrete is hard by light chipping wire brushing. 3. Preparation of construction joints shall be done by mechanical chipping taking care

not to dislodge the coarse aggregates. This is to be done at least 24 hours after the completion of placing or a concrete surface retarder may be use.

4. Concrete have to be cured by sweet water as instruction by client/consultant all the surface of foundation will be covered by wet sacks cloth to maintain this.

Construction Joints

Construction joints shall be in the locations as indicated in the drawings, or as sub-mitted in a proposal and always at right angles to the structural member’s axis.

9. Environmental and Social Pre-Construction Description

Land and Water Use in the Area

Previous land use of the area to be developed as the construction site of Main Intake, Inlet and Outlet Canals was mainly used for agriculture practices which include shifting cultiva-tion and seasonal cropping, corn and other cash crops. Recently, the land was compen-sated and there were less agriculture practice and the land was covered by young fallow and bamboo forest. Proximity to Village and Cultural Site The construction site is located about 3 km from existing Houay Soup resettlement village. Because of a distance, it is unlikely to cause environmental and social impacts to the near-by village. There was no report on the nearby cultural sites, thus no impact is expected. However, a “chance find procedures” is provided in this SSESMMP to ensure that NNP1 is notified if any chance-find cultural objects are identified in the construction site.

Environmental Assessment Checklist Table 5 below is a checklist of pre-construction to assess any potential environmental and social impacts and their mitigation measures. After the checklist has been completed, the Sub-Plans can be selected accordingly. Table 5 Environmental Assessment Checklist- for Pre Construction

10. Sub-Plan Detail for the Construction of Main Intake; Inlet/Outlet

and irrigation Canals - Environmental

All Sub-Plans in this section refer to construction activities unless otherwise mentioned.

SP-01 Erosion and Sediment Control

An open ditch will be installed around the camp to collect and divert run-off;

Topsoil shall be removed and temporarily stockpiled along the canal alignment for cover-

ing the canal embankment to allow vegetation growth. It is expected to collect a total of

48 m3 of topsoil during earth work;

Based on the Bill of Quantity (BOQ), following are the scope of work related to ero-

sion control at the KCP construction site during the work execution of the:

a. According to the actual site condition, initial erosion and sediment controls,

such as sediment ponds are not needed because of no close approximate

water resources. The site is already located in the low land area which

has no potential for sediment runoff problem;

b. Waste rock and unsuitable spoil shall be disposed at location approved by NNP1PC

as indicated in figure 2 and Appendix 3. The expected amount of waste rock and un-

suitable spoil is 2,000 m3. Therefore, with the given disposal area of 50 m by 50 m,

the height of spoil disposal area shall not be higher than 1m;

c. Spoil disposal site shall not need a construction of drainage control and sediment

pond because it is less than 3 m in height. However, wet and dried vegetation from

clearing work shall not be burnt but will be used as a cover material for spoil em-

bankment. In addition waste rock shall be also placed at the spoil embankment to

help protect from erosion;

d. Areas within the construction areas which is not required to be disturbed by construction activities will be maintained in their existing conditions;

e. Any further requirements for additional work including the construction erosion con-trol system (drainage lines, sediment ponds, rip rap, sodding, etc shall need further discussion with the client).

SP-02 Water Availability and Pollution Control

Oil storage will have impermeable flooring and be prevented from rain, No workshop for

KCP, If minor fixing is required, it shall be conducted at the construction site (not at the

22

camp site). The oil protection tray and absorbent sand/saw dust shall be used to collect

oil spills. Major fixing shall be conducted offsite where acceptable workshop is availa-

ble;

Implementation of solid and septic system waste, management systems,

such as proper location, containment and construction worker camp trash,

and appropriate location (at least 30 m from drainage courses or other sensitive areas)

and containment of septic systems;

The contractors shall provide sanitation facilities /2 toilets with septic tanks with suffi-

cient capacity to handle and treat domestic wastewater generated by workers. Waste

water from septic tank shall be pumped, treated with lime and disposed in accordance

to the NNP1PC’s requirement (KCP will be consulting with the owner for detail man-

agement of septic tank waste water).

SP-05 Waste Management

Solid waste must be separated, collected and kept at existing worker camps for dis-posal at Houay Soup Landfill in coordination with EMO.

Dumping of waste into watercourses, agricultural land and surrounding areas is highly

prohibited;

A sufficient number of waste containers or similar one will be made available

at the survey site;

Waste containers will be marked clearly for “Hazardous Waste” and for “Non-Hazardous

Waste” for separation and sorting of waste; Construction waste will be minimized by applying the waste minimization hierarchy

principles of ‘Avoid/Reduce/Re-Use/Recycle/Dispose’. Any waste material that is unable to be re-used, re-processed or recycled will be dis-

posed at a facility approved to receive that type of waste;

Waste will be stored in appropriate facilities (e.g. bins, stockpiles), with hazardous

waste stored away from streams and rivers in secure areas;

Secure lids will be fitted to bins that store food waste to prevent scavenging by birds

and animals.

SP-06 Hazardous Material Management

All chemicals and waste considered as potentially hazardous materials will be regis-

tered in order to follow up type, quantities stored, quantities used or generated;

Personal protective equipment (PPE) will be provided to all workers and the use of

equipment will be enforced;

Safety procedures regarding fire and accidental spill management to be posted on-site;

“No Smoking” labels and posters will be placed when river fuel is handled or stored;

All the fuel and hazardous material storage will be in adequately bundled areas to min-

imize the risk of spillage;

Only fuel drums with a maximum accumulation capacity of about 5m3 will be stored at

the fuel storage at the KCP camp. The storage shall be within an enclosed and cov-

ered secure area that has an impervious floor and impervious bund around it. The

storage area will be located at least 30 m away from watercourses, flood-prone areas,

main accommodations and workshop areas.

All re-fueling of machinery will be undertaken by a service vehicle, with appropriate

safeguards and protection measures to prevent any spillage or contamination by chem-

ical wastes or maintenance oils, lubricants etc.

23

The hazardous materials and chemical used in the construction shall be separated and

kept in a suitable storage and the Material Safety Data Sheet (MSDS) shall be in place;

Firefighting equipment will be kept available next to each storage facility;

Ensure availability of spill clean-up materials (e.g., absorbent pads, etc.) specifically,

designed for petroleum products and other hazardous substances where such

materials are being stored and used. If spills or leaks do occur, undertake immediate

clean up.

SP-07 Vegetation Clearing

Before the construction start, vegetation cover such as bamboo young fallow shall be

cleared for the construction area.

The clearing line is 5m of both sides of canal alignment from ST0+100 to ST1+600. The

clearing line shall be survey and demarcated, clearing outside the boundary is prohibit-

ed. Alignment coordinates are shown in appendix 1.

Cleared vegetation which is mainly bamboo and bush will not be burnt but will used as

cover material for spoil embankment to help protect spoil erosion shown in figure 2 and

Appendix 3. Detail scope of erosion control can be referred to SP01 as above.

The proposed construction area was surveyed and demarcated. In any case, if there

are valuable trees found in the clearing area, it will be informed to PoNRE of

Bolikhamxay district and province for removal permission;

No extra clearing will be required outside the demarcated areas.

SP-08 Landscaping and Re-vegetation

All area disturbed by construction activity will be, as far as reasonably possible, land-

scaped to reflect natural contours and restore suitable drainage paths.

Topsoil of estimated of about 48 m3 from earthwork shall be reused as the final cover of

the canal embankment to support natural growth. Plese note that revegetstion of

KCP construction site is out of scope of work as stated in the Bill of Quantity

(BOQ).

As part of a minimal site landscaping, spoil disposal embankment shall be protected as

must as feasible such as the use waste vegetation and waste rock as embankment

cover.

The KCP camp site shall be landscaped properly by following the attached site demoli-

tion and decommissioning plan.

SP-09 Biodiversity Management

The extent of all works shall be surveyed and clearly pegged prior to the commence-

ment of any construction activities.

Workers are prohibited from the buying, hunting and consuming wildlife in the Project

Construction Area including fishing in Houay Soup and Nam Ngiep. Wild flowers and

plants shall not be kept and traded by the workers of the Contractor.

Biodiversity management rules shall be included in worker camp rules and shall be

strickly supervised by KCP’s supervisor.

SP-10 Spoil Disposal

Workers responsible for spoil handling and disposal shall be instructed by the Contrac-

tor or its nominated sub-contractor about the correct/approved placement and compac-

tion of spoil. The approved location for spoil disposal as shown in appendix 3.

Excess spoil such as waste rock and unsuitable spoil of about 2,000m3 shall be dis-

posed of at approved site, with landforms created as per the SP10: Spoil Management

Plan.

The spoil disposal boundary shall be pegged and checked by the owner’s engineer or environmental staff prior to the commencement of site preparation works.

Spoil shall be shaped into stable landforms, with permanent drains installed to maintain

landform stability and prevent erosion. Final landform slopes shall not exceed 1:2.0

(V:H).

Waste rock and unsuitable spoil shall be disposed at location approved by NNP1PC as

indicated in figure 2 and Appendix 3. The expected amount of waste rock and unsuitable

spoil is 2,000 m3. Therefore, with the given disposal area of 50 m by 50 m, the height of

spoil disposal area shall not be higher than 1m;

Spoil disposal site shall not need a construction of drainage control and sediment pond

because it is less than 3 m in height. However, wet and dried vegetation from clearing

work shall not be burnt but will be used as a cover material for spoil embankment. In ad-

dition waste rock shall be also placed at the spoil embankment to help protect from ero-

sion;

Areas within the construction areas which is not required to be disturbed by con-

struction activities will be maintained in their existing conditions;

Any further requirements for additional work including the construction erosion control

system (drainage lines, sediment ponds, rip rap, sodding, etc shall need further discus-

sion with the client).

Adequate compaction of all placed fill shall be provided. This will generally be achieved

by laying the fill in horizontal layers not exceeding 50 - 100 cm depth and compacting

with bulldozer.

Spoil disposal embankment shall be protected as must as feasible such as the use

waste vegetation and waste rock as embankment cover.

SP-13 Construction of Workers Camp

The existing KCP worker camp facilities will be used as support the construction of In-

let, outlet and canal as follow:

toilet. The septic tanks will be treated properly together with other camp facilities during

the decommissioning period in accordance to the Site Decommissioning Plan approved

by NNP1PC-EMO.

The worker camp will be surrounded by an open ditch, which will collect runoff water

and treated waste water from kitchens and washrooms. All will drain into a sediment

pond before being discharged.

Waste bins will be distributed around the camp site at main locations such as; kitchen

and lunch areas, accommodation building and wash rooms. A minimum of two bins

will be provided for each location; (1) recycling (2) general waste. A central point will

then be used to collect all waste for later disposal at landfill. Dumping of waste into wa-

tercourses, agricultural land and surrounding areas is highly prohibited.
