Contractor Registration Click here to apply for the service

In accordance with Chapter II, clause 2.3.1 of Procurement Rules and Regulations 2009, the Construction Development Board (CDB) shall be the competent authority of the Government to establish and maintain the List of Registered Contractors and Consultants for Works as specified under clause of Procurement Rules and Regulations 2009.

Accordingly, the Construction Development Board (CDB) has developed a online registration system called e-Zotin, wherein all Contractors who wish to participate in the contracting/consultancy job of construction sector in Bhutan must first be registered through online with the CDB.   

The classification, categorization and registration of Contractors by the Construction Development Board through the use of uniform procedures and criteria, provides a quick access to updated records of Contractors and avoid possible irregularities attributed to adhoc/multiple/inconsistent registration.

The procuring agencies could specify the additional requirement (depending on specific jobs) to that provided in the evaluation of potential Contractors. The requirements will vary greatly with the nature of the projects. The specific requirements will be established and assessed in the tender documents during the bidding stage of those projects.

The Contractors will be Classified into Three Class, namely Class Large, Class Medium, and Class Small. The scope of their activities will be categorized into W1, W2, and W3 & W4 (for detail refer "Categorization of Infrastructure Projects")

The registration system is a process of formal pre-qualification and is not limited to a particular contract or project. Proof of enrollment on the CDB Registration System will constitute a presumption of overall suitability and will qualify Contractors to participate in the bidding of government or other public work projects. The system prevents the need for formal pre-qualification process of Contractors, and therefore allows the government contracts to be awarded and executed faster.


The Construction Development Board (CDB) has developed a Contractors Registration System based upon a classification of Contractors and Categorization of Works. The registration of Contractors, re-registration, up-gradation, and any matters related to Contractors registration shall be carried out strictly in accordance with the specified principles and procedures.  

CDB Registration requirement henceforth shall apply to JVs (amongst National Contractors/Consultants or with Foreign Contractors/Consultants) & also to independent Foreign Construction or Consultancy Firms if they wish to participate in contract/consultancy works in Bhutan. 

All Ministries/Departments/Agencies (government corporate agencies) concerned in the public sector shall use these Registered Contractors/Consultants according to their classifications and categories in the execution of infrastructure projects. The private sectors & the NGOs are also encouraged to use the same.


All Bhutanese citizens having attained the age of 18 years shall be eligible to register. All Bhutanese are permitted to undertake business in any Dzongkhag of their choice. Census registration or ownership of landed property in a particular Dzongkhag shall not be a condition for eligibility to registration.

An applicant shall be entitled to only one Registration Certificate within the Kingdom.

The fees for registration shall be levied as per the "Schedule of fees".

Scope of Registration

Contractors shall be classified and registered under one of three classifications namely: Small, Medium and Large for each category of Projects.

Validity of Certificate of Registration

Contractors who have been duly registered with the Construction Development Board will be issued a Certificate of Registration valid for a period of two years.

At any time during the validity period of the Certificate of Registration, the Contractors may submit a request in the approved application form for upgrading of his category and/or for additional classification Headings/Sub-headings.

A late fee of Nu. 100 per day shall be levied for each day of delay (with 1 month of grace period after the expiry of the validity period) subjected to maximum of Nu. 3000.00 for Small. The renewal of the certificate of registration MUST be applied within thirty (30) days of its expiration date. 

Categorization of Infrastructure Projects

Infrastructure projects will be categorized into 4 separate Headings itemized under reference W1 to W4. Each heading generally covers the types of works that are executed under the Government's infrastructure program. A brief description of each Heading is given below:

Infrastructure Projects Categories
Categories Headings Description
W1 Roads & Bridges Construction of roads (laterite, prime and seal Flexible or rigid pavement); timber or concrete or steel bridges, culverts, surface drainage, kerbs, footways, pedestrian overhead crossings, airport runways and aprons

Laying ducts and construction of junction boxes and of manholes for telephone cable networks.

Permissible work volumes & values of Contractors

The Contractors will be classified according to his/her capabilities for each category of work. There are three classifications ranging from Large to Small. Contractors' classification will determine the size of construction works that he/she is eligible to undertake, as well as the maximum number of contracts that can be awarded at a time.

Details (Large) (Medium) (Small)
Eligible bid amount (million Nu) > 15 million 4 – 15 million ≤ 4 million
Maximum number of contracts at a time 5 Nos. 4 Nos. 2 (provided the total amounts is < 4mn)
Maximum value of contracts at a time (million Nu) No ceiling No ceiling 4 million

Note: The above values are based on the agencies estimate and not the quoted value.

Classification is based upon the Contractors' human resources & equipment and facilities. For upgrading of classification and/or to request other categories of work, the Contractors may apply for an additional cateogry through online (e-zotin).

Because a Contractors classification is partly determined by their experience in a sector, it is anticipated that Contractors will maintain different classifications for different categories of work. For example, a Contractor may be eligible as a "Medium" Contractors for category W1 (Roads and Bridges), yet only be eligible as a "Medium" Contractors for category W3 (Buildings). In this case, the Contractors will maintain 2 classifications.

W2 will not have any Class such as Small, Medium and Large.
