1. INTRODUCTION

Flood and landslide damage mitigation measures consist of structure measures and non-structure measures. The structure measures for the Master Plan and Priority Project consist of flood damage mitigation works and landslide damage mitigation works.

Flood damage mitigation works consist of earth excavation, rock excavation, revetment, parapet wall, shaft works, counterweight fill, anchor works, spoil bank, Mallol bridge (replacement), Mallol bridge (reinforcement), Pescado lake outlet improvement, replacement of sewage pipe, and replacement of water supply. Landslide damage mitigation works consist of earthwork and drainage facility works for Berrinche, Reparto and Bambu sites.

Non-structure measures consist of watershed management, warning system for flood damage mitigation, and resettlement and warning system for landslide damage mitigation.

2. FACILITY PLAN

(1) Revetment

Revetment along the river is needed to stabilize the bank against erosion and sliding where built-up area is just next to the river. Revetment works are divided into following three types.

1) Revetment (A): Revetment (A) is a stone-masonry type to be constructed at reach (C40-C60) in the priority project. The revetment (A) is 8m heights, and total length of revetment (A) is about 2.5km.

2) Revetment (B): Revetment (B) is a stone-masonry type to be constructed at part of revetment construction in Master Plan excluding part of between C40 and C60. The revetment (B) is 8m heights, and total length of revetment (B) is about 5.2km.

3) Gabion: Gabion is a gabion mattress type. Gabion mattress is 0.3m thicknesses, and total length of gabion is about 5.2km Gabion mattress is placed temporarily against bank erosion at part of revetment (B) construction in Master Plan excluding part of between C40 and C60. The stone of Gabion mattress is reused as a material of Stone-masonry of revetment (B).

(2) Spoil-Bank

Planned spoil-bank is located at C0-C10. River excavation volume of Priority Project is about 709,000m3. Excavation volume of Repart landslide site is about 40,000m3. Berrinche counterweight fills volume is 40,000m3. Therefore, 709,000m3 volume is transported to the spoil-bank. There are two spoil-banks. Downstream spoil-bank is about 135,000m2 and upper stream spoil-bank is about 63,000m2. Downstream spoil-bank is used for Priority Project. Gabion wall of 4m high surrounds the bank. 400m revetments for chicken farms are planned. 300m parapets are also planned for chicken farms of upper reach.

(3) Shaft works for small-scale landslide near Berrinche landslide

Shaft works on the left bank side planned L=387m to C47-C50 (52 peaces). The paling is


K - 2

made the reinforced concrete of the diameter 4m and 16m in length. The paling arrangement is assumed to be one row along the river improvement route. (Figure K.2.1)

Drainage boring (D10cm, L=50m) is installed at 6m intervals for lowering of ground-water level against the stability of small-scale landslide. (Figure K.2.2)

(4) Anchor works for Right Bank at Berrinche

Anchor works were planned against right bank at Berrinche because of following limit. (Figure K.2.3, Figure K.2.4, Figure K.2.5)

1) There is a boundary line between river area and commercial area by the Planning Department of Tegucigalpa City.

2) Construction of common revetment is difficult because of no space to construct. There are structures such as a church, a school and a police station in close proximity.

3) The height of the cantilever wall becomes 15m in including footing thickness, and it is not allowable, because that height is more than limit of height of cantilever wall (10m).

And, there are school, church and the police behind the revetment. Therefore, stone masonry and cantilever wall types are impossible to construct without destruction the foundation of those structures. Only concrete wall with earth retention by tieback anchor is possible to construct.

4) The earth retention by tieback anchor is needed as the earth retaining under excavation and it is used as permanent anchor after construction works.

Anchor works is 120m long at C47-C48. Its structure is steel frame concrete wall with 1m thickness. H steel frame is type of H300 x B300. Anchor materials remain at under ground of adjacent structures after construction wall.

(5) Replacement of Mallol Bridge

Planned new bridge is a solid-spandrel arch type and has 4 piers, like Carias Bridge. While the existing flow area of Mallol Bridge is only about 300m2, the planned flow area is 480 m2. (Figure K.2.6, Figure K.2.7)

(6) Outlet of the Pescado Lake

Following counter measures are planned in order to prevent reduce outlet width of the Pescado Lake. (Figure K.2.8)

1) Placing of gabion-mattress, which is 15m wide, 60m long and 0.5m thick, at outlet. 2) Placing of gabion wall, which is 2m wide, 3m high and 60m long, at left and right slope

sides. 3) Cut of slope, which is in danger of collapse at right side slope. 4) Make of spoil bank, 50m lengths, 10m widths and 2m height for cutting soil of slope. 5) Make of stone-masonry wall, which is 1m widths, 2m height and total 70m lengths, for

spoil-bank.

(7) Remove of Water Supply and Sewage pipes

Water supply pipes cross the river. Elevation of those pipes is higher than planned riverbed elevation. Therefore, those pipes (total 1,200m) are needed to remove under planned riverbed. Sewage pipes run along the Choluteca River. There are sewage pipes in excavation area of Master Plan. But some pipes are not used. Elevation of those pipes is not sure. Therefore, sewage pipes removing of about 1,100m (20 % of total length of sewage pipes in the reach of


K - 3

C27-C93) are planned in Master Plan Project.

3. CONSTRUCTION PLAN

3.1 BASIS OF CONSTRUCTION PLAN

The construction plan for the execution of Master Plan and Priority Project was prepared on the basis of following assumption and consideration.

3.1.1 CONSTRUCTION PERIOD

Construction period of the Master Plan was assumed to be 15 years in due consideration of quantity of works, funding and realization of flood control effects at early stage. Construction of the Priority Project will be carried out in 4 years at the initial stage of the Master Plan.

3.1.2 PROCUREMENT OF WORKS

Construction works were assumed to be procured through a package contract system by international tendering.

3.2 CALCULATION OF WORKABLE DAYS

(1) Public Holidays

Working days for construction works are counted by the calendar of year 2001 in accordance with the custom and public holidays in the Honduran society.

The national holidays in Honduras of this year (2001) are as follows.

① 1 January New Year’s Day

② 12 April Maundy Thursday

③ 13 April Good Friday

④ 1 May Labour Day

⑤ 15 September Independence Day

⑥ 3 October Morazán Day

⑦ 12 October Columbus Day

⑧ 25 December Christmas Day

(2) Holidays and Half-holidays

Saturdays are half-holidays and Sundays are full-holidays based on the custom of Honduras. While, the next Saturday of Good Friday is treated as a working day.

(3) Working Days

Working days are counted on the calendar as follows.

① from May to October: 141 days (23.5 days/month)

② from November to April: 138 days (23.0 days/month)

③ Average through a year: 23 days/month *Daily working hour is assumed to be eight (8) hour.

(4) Number of Rainfall days 1) Rainfall Information

The study is based on the information of number of days of rainfall (over 10 mm, Table K.3.1) of each month and monthly rainfall data in Tegucigalpa (Table K.3.2) during the period from 1963 to 1999. The information of rainfall is divided into the rainy season (May – October) and the dry season (November – April) in the following study.

2) Rainfall

Yearly rainfall in Tegucigalpa shows the extent within 500 – 1,300mm and amount of annual mean rainfall is given as about 900mm/year. Most part of the rainfall occurs in the rainy season from May to October and it has about 800 mm of precipitation in the half year of rainy season. The precipitation in the dry season from November to April is about 100 mm.

3) Number of Rainfall Days

Number of rainfall days (over 10 mm) of each month shows obvious difference between rainy season and dry season. In rainy season, rainfall day counts for 3 – 6 days per month and the number of days of rainfall in a half year shows 26.4 days. In dry season, days of rainfall counts for 1 – 2 days and the number of days of rainfall is 7.6 days in the average of 38 years.

4) Rainfall per One Rainy Day

Rainfall per one rainy day is calculated using combination of the data of monthly rainfall and number of rainy days and each month, and the results are 19 – 26 mm/day in rainy season and 12 – 26 mm/day in dry season (Table K.3.3). The averaged rainfall in one rainy day is seen rather high according to the results.

(4) Calculation of Workable Days

Workable days of earthworks are calculated in the combination of working days by calendar and number of days of rainfall as follows.

1) Rainy Season (May – October), 184 Days

Number of rainfall days: 26.4 days

Probability of a certain day to be a rainy day = 26.4 / 184 = 0.143


Those are independent events each other and the probability of a certain day to be a working day and not to be a rainy day is calculated as

0.769 X ( 1 – 0.143 ) = 0.659

Number of workable days in rainy season is

0.659 X 184 days = 121.3 days (about 20 days/month)

2) Dry Season (November – April), 181 Days

Number of rainfall days: 7.6 days


Probability of a certain day to be a rainy day = 137 / 181 = 0.757

Those are independent events each other and the probability of a certain day to be a working day and not to be a rainy day is calculated as

0.757 X ( 1 – 0.042 ) = 0.725

Number of workable days in rainy season is

0.725 X 181 days = 131.2 days (about 22 days/month)

Therefore, the monthly-average operation days of the construction work become the 21 days.

As for others works that will not be affected by rain or weather, the number of workable days is estimated as 23 days/month through a year.

(3) Construction Method

Construction method was discussed so that work quantities mentioned above would distribute uniformly throughout the construction period. As a result, the following construction method and construction period were proposed:

1) Earth Excavation: Excavation is carried out by backhoe (0.6 m3) and dump truck (10 ton) which is largest truck of the highway use.

Excavation material is conveyed by 10-ton dump truck through river. The distance of transportation is assumed to be 5.4km on the average. (Figure K.3.1)

2) Revetment works: Revetment is constructed as stone-masonry as it is a common practice in Tegucigalpa.

3) Parapet wall: Parapet wall is constructed as stone-masonry as it is a common practice in Tegucigalpa.

4) Shaft works: Shaft is excavated by small backhoe.

5) Anchor works: The H steel piles are driven at intervals of 3m

The H steel piles are anchored by tendons at 1m, 4m and 7m depth respectively. Tendon is used by steel-bar. Excavation for construction of retaining wall is carried out after anchoring. Tension is carried out again after construction of retaining wall.

6) Spoil Bank: The excavated materials are hauled to the disposal areas by dump truck (10 ton). The hauling distance is assumed to be 6.5 km on an average.

7) Mallol Bridge: The bridge is constructed by RC-concrete. The bridge has 4 piers and 2 abutments. The bridge length is 100 m and width is 12 m.

However, at the Priority Project stage, only the pier foundation is reinforced. (Figure K.3.2)

8) Replacement of Sewage Pipe: Replacement lengths of Sewage Pipe are 1,100 m and 500 m for Master Plan and Priority Project respectively.

9) Replacement of Water Supply: Replacement lengths of Water Supply are 1,200 m and 500m for Master Plan and Priority Project respectively.

10) Landslide mitigation works of Berrinche: 4 drainages well are constructed against drainage of ground water. Channel works are constructed against drainage of surface water. Diameter of wells is 3.5m, and depth is 30m.

11) Landslide mitigation works of Reparto: 2 drainages well are constructed against drainage of ground water. Channel works are constructed against drainage of surface water. Diameter of wells is 3.5 m, and depth is 15 m.

12) Landslide mitigation works of Bambu: Channel works are constructed against drainage of surface water.


K - 10

13) Counter Weight Fill: Counterweight fills is planned against landslide at left bank in the C45-C47. (Figure K.3.3)

4. MAINTENANCE PLAN

Maintenance was planned according to the following conditions.

1. Maintenance of flood mitigation facilities, which are revetment, parapet wall and earth retention by tieback anchor, is carried out for 50 years.

2. Maintenance cost per year for the facilities is estimated to be 0.5 % of direct construction cost of the facilities.

3. Damage cost by floods per 15 years is assumed to be 10% of direct construction cost of the facilities.

4. Life years of observation facilities of forecast/warning is assumed to be 10years. Renewal cost of the facilities is appropriated every 10 years. Maintenance cost per year for the facilities is estimated to be 0.5 % of cost of the facilities.

(1) Maintenance of Anchor Works

The purpose of maintenance of anchor works is to confirm the planned function. It is necessary to repair when the function of anchor works is insufficient.

In doing maintenance, it is necessary to arrange the anchoring record and keep it.

Items of observation and measurement of anchoring are as follows.

1) Load and displacement caused in anchor bar

2) Displacement and movement of structure

3) Movement and erosional condition of anchor head

4) Groundwater level

5) Others

The check, observation, and measurement for maintenance should be continued during anchoring.

(2) Maintenance of landslide-countermeasures facilities

The purposes of the maintenance of landslide-countermeasures facilities are to prevent decrease of function of the landslide-countermeasures facilities, against reactivation of the landslide.

Landslide-countermeasures facilities of Berrinche are water channel work, horizontal boring works, drainage well, and shaft works etc.

In case something wrong of these facilities is founded, the function of facilities should be recovered by investigation and repairs.

In particular, drainage function of strainer of catchment boring hole of drainage well decrease in


K - 11

several years after construction, because strainer is clogged with soil. In this case, the strainer should be washed.

And, the horizontal drainpipes from the drainage well also regularly should be checked.

5. BASIS OF COST ESTIMATE

The project cost consists of costs for the following items:

1) Construction base cost

- Structure measures - Non-Structure measures

2) Administration

3) Engineering service

4) Physical contingency

The project cost was estimated based on the following conditions and assumptions:

(1) Unit Prices of Labor, Material and Equipment

The unit price of labor wages, construction materials and equipment are based on the Standard price of Honduras. (Camara Hondurena de la industria de la construccion (CHICO)).

Construction price index of Japan in August 2001 is used in case of no price description in the CHICO.

(2) Production rate of the Work:

Production rate of the work is expressed based on following data.

? Standards for Cost Estimations of Public Works (Ministry of Land, Infrastructure and Transport, the Government of Japan; 2001)

? Tables of depreciation cost of construction equipment (Japan Construction Mechanization Association; 2001)

(3) The cost of general temporary works: The cost of general temporary works is assumed to be 20 % of the direct construction cost to calculate construction base cost.

(4) The indirect cost: The indirect cost (7.5 % of the accumulated direct construction cost is assumed empirically) which consists of overhead expenses, profit and so on, is added to calculation the construction base cost.

(5) Exchange Rate of Currencies: The basic prices for import products are estimated based on the exchange rate of currencies as follows (November 1, 2001);

1 US Dollar = 122.44 J Yen = 15.84 Lempiras.

(6) Engineering Service Cost: Engineering service cost is assumed as 15% of the total of construction cost.

(7) Physical Contingency: A physical contingency is required for the construction work and


K - 12

is estimated empirically as 10 % of construction cost.

(8) Administration Cost: Administration cost (be borne by the administrative agency of the construction project) is estimated as 5 % of the summation of construction cost.

(9) O/M Cost: The operation and maintenance cost at full operation stage of facilities after the completion of construction works was assumed to be annually 0.5 % of the total construction cost.

6. UNIT PRICE/COST

10. NOTE OF SUPERVISION OF CONSTRUCTION WORK

In the construction of the shaft work of Berrinche, following matter should be noted.

1) In the first place, the drainage boring should be constructed, and the ground-water level should be lowered.

2) Continuous construction of the shaft works should not be done, because it causes the landslide.

3) In the construction of the shaft works, geologic map and photograph should be recorded for safety management and maintenance.


K - 17

4) The strain gauge, the reinforcing bar stress transducer, the clinometers, and the earth pressure gauge for the landslide observations should be installed, and the data of observation should be used for the safety management and maintenance of construction of shaft works.
