Blacktopping of Dakpai-Buli-Nimshong GC Road

Dakpai-Buli-Nimshong GC Road starts at Dakpai, 18.00 km on Tingtibi – Zhemgang SNH at an altitude of 1263 m. It traverses through forest touching many villages until Buli (36.60 km), 1698 m. The highest elevation, it passes between Dakpai & Buli is at Talila (18.00 km), 2014 m.

From Buli, the road inclines up through randomly dense forest till Gonglithang (5.10 km), 2154 m. The road further inclines up through the continuously dense forest & crosses Malaya top (10.50 km) at an altitude of 2626 m. The road, then declines down until Rongdigang (19.60 km), 1833 m and incline bit up with four short zigs. Further it traverses straight until Churmulung (25.50 km), 1937 m and then decline down till Nimshong (30.20 km), 1740 m.

The road, Dakpai-Buli was constructed in early years of ninth fifth year plan and Buli-Nimshong road was constructed in later years of 10th fifth year plan.
Blacktopping work in progress at Nimshong
From the above alignment description of the road, it is clear that the road stretch from Dakpai to Buli (36.60 km) passes through uniform elevation variation. Whereas, the road stretch from Buli crosses the highest elevation variation. Due to high elevation and dense forest cover along Gonglithang until Rongdigang, the road corridor and the pavement in particular receive less sun, leaving the road stretch marshy and damp throughout the year.

Although major sections of the road have been blacktopped, it is observed deterioration of wearing coarse in the form of potholes; alligator cracks, depression distress, shoving etc. At certain stretch, the gross failures of pavement are observed.

Due to more damp and marshy locations, almost 2.40 km of road beyond Malaya towards Nimshong were left without blacktopping.
Road stretch through dense jungle beyond Malaya
To forgo the blacktopping of marshy sections, discussion were held in various meetings and even in Department’s Quarterly meeting and resolute the same.

That’s why, certain stretch along Buli to Nimshong GC (2.40 km out of 30.20 km target) road was not blacktopped. Nonetheless, estimates for the remaining pavement improvement works have been prepared inclusive of cross drainage and road drainage for the betterment of smooth road along the high elevation ranges. 

I generously regret the inconveniences caused to the public of Upper Kheng, UK.

Life Cycle Cost Awareness in Bhutanese Construction Industry

A book published. Self authored. Go through the abstract. Thank you. 

Significant knowledge gaps exist in the knowledge of Life Cycle Costing and the alternatives selection of building materials in the construction industry. In order to fulfill the gaps a questionnaire survey was developed for 319 respondents in using the Life Cycle Costing for the Bhutanese construction industry. Life Cycle Cost Analysis of selected components of the selected building was done taking into account relevant economic factors: initial costs, maintenance and operational costs.

The maintenance and operation costs are generally ignored in building industry especially in design stage. For this research, the method of LCC, present worth cost approach was evaluated with projection of building service life as 60 years, inflation rate as 9.07% and discount rate as 0%.

A book published by Lambert Academic Publishing 

About 52% of the respondents do not have idea about LCC when making investment decisions nor do they not take maintenance, operation and replacement cost into consideration. The lack of significant input-cost data and lack of experience appears to be the most important problem supported by 78% responded lack of experience and 62% responded lack of significant input-cost data.

The LCC analysis showed that ceramic tiles, pre-painted CGI sheet and LED lamp has the lowest life cycle cost among the many material alternatives available in the market, that is, 16% for LED lamp, 13% for ceramic tiles and 64% for pre-painted CGI sheet.

Gold Mother

Mostly wander I swing deprived missing nearby eatable,
In the golden fur of beautiful raiment cover.

Jumping madly off the branches with mates
And peaceful rest to feed kiddo makes the wander wonder.

Golden Langur of Zhemgang

Profound dark face; golden raiment cover of gold & long extreme tail
You are named Golden Langur. 

Languorous care for the little one on the creepy branches,
Lively lovely gold mother, I see in you as I stare.
I recede with smile...

Some years ago, I promise to keep my blog up-to-date. That was when I was a college student. Exactly, with the new beginning of 2017 I am two years in service. Student and working life is two complete different things. The focus target being student is only one - study. Service life comes with numerous plans and targets. Moreover working with road sector, someone needs to adjust with many ad hoc activities and get least time to sit in office and do paper works.
More than seventy percent of time is spent out of office at sites monitoring and supervising various works. It is tough at times especially during monsoon seasons. Better I don't elaborate more on my working life now. I will share my experiences in times to come. In the meantime, I have few resolutions for the year which both concern my professional and personal life.
1.       Ghat tracing survey to connect Zhemgang and Mongar
2.        Walk from Khomshar to Ringdibi
3.       Read 20 books
4.       Learn Total Station instrument and LisCAD software fully
5.       Write life experiences as road engineer
6.       Learn RevitArchitect software fully and design Sub-Division office
7.       Reduce site visit and spend more time in office.
8.       Learn driving & basic mechanics of car  
9.       Learn more photography skills

Financial Year 2016 - 2017

The road history of Upper Kheng (UK) is under making. The most controversial GC road construction in the history of Department of Roads has been completed. Formation cutting for additional length of 1.24km to the newly proposed Gewog centre is yet to complete with trace cutting already reached its termination point. Formation cutting of Bardo Gewog centre road (Therang - Khomshar GC road) will be completed within this financial year 2016 -2017. Trace cutting has already been terminated at the Gewog centre. 
Beautiful Khomshar before road construction
Survey work for the new road that will connect Khomshar under Zhemgang and Wama under Mongar Dzongkhag is underway with Lingmithang regional office undertaking the feasibility survey. The road construction activity is in 12th fifth year plan. The road will connect central and Eastern Dzongkhag. 

Construction completion of GC roads has welcomed many farm roads under Shingkhar and Bardo Gewogs. Within 2015 -2016 financial year, two farm roads to Radhi and Thrisa village with 7.10 km and 9.17km respectively started its construction. Another two farm roads to Changkhar and Thajong is yet to start. 

Bardo Gewog's farm roads to Phulabi and Dratshang (Gonpa) awaits for trace cutting of GC road to reach Gewog centre since all takeoff points of the farm roads are from Gewog centre. Factually, UK's development mode is on. 
Thrisa Farm road takeoff from GC road
With Chamkharchu Hydropower soon to start, roads condition and people's lives will be drastically improved. 

Nimshong Sub-division office is mandated for management of road projects of UK. It has blacktopping and maintenance of Buli - Nimshong (30.2km) and Phumithang Dratshang (3.35km), formation cutting of Shingkhar and Bardo GC roads works at hand. 

Budget proposal for the fiscal year 2016 - 2017 amounting to roughly Nu. 150.00 million was farsighted move. Among various proposed improvement activities of GC roads, budget for construction of only three Bailey bridges were approved with RGoB financing. 

Government has pledged and prioritized blacktopping of all Gewog centre roads within 2018.  Within those two financial years period, Shingkhar GC and Bardo GC road till Bardo contemplate to complete. The total GC roads to blacktop lengthen to 59.06km after completion of Therang - Khomshar GC road. 

Therefore, as per the fiscal budget approval and work plan accordingly, I wish for timely release of the budget and timely completion of work.
