for ICPs at Rinchending & Bumpagang, Chukha. (AUGUST 2019)

Ministry of Works and Human Settlement




I. BACKGROUND

In order to strengthen national security and maintain law and order, it is imperative that

proper mechanisms be put in place which are efficient and user friendly. With the

concept approval from His Majesty the king on 10th

April, 2015, Department of

Engineering Services is blessed to be bestowed to undertake construction of two

Integrated Check post at Rinchending and Bumpagang.

Rinchending is located approximately four kilometres from Phuentsholing main town

and Bumpagang is approximately 80 kilometres from Phuentsholing.

There is a temporary security arrangement set up at Rinchending but Bumpagang is an

open thoroughfare for the commuters. The existing infrastructures at Rinchending are

not adequate for efficient functioning of the checkpoints given the importance of its

services. Further, different government agencies have installed their respective counter

randomly which is cumbersome to the commuters. Therefore, the establishment of

check point should not only for facilitate the enhancement of security, but also enhance

effective and efficient delivery of the services depicting the country’s image and status

to outsiders.

As of now, the construction of elevated flyover deck on which the gates and offices are

proposed is complete at Rinchending and the site clearance work for construction of

offices and gates at Bumpagang has been completed.

The Department of Engineering Services envisages constructing Offices and gates for

Integrated Check post at both the locations which is functionally proficient and

aesthetically very presentable.

II. ELIGIBILITY of BIDDERS:
