A BUJKA is the representative office a large foreign construction firm opens to work on major projects in Indonesia. It runs on construction certifications, SBU and SKK, and works through a joint operation with a local construction company.

A BUJKA, the Badan Usaha Jasa Konstruksi Asing, is the representative office a foreign construction services company opens in Indonesia. It is governed by Government Regulation 5/2021 and licensed through the OSS Risk-Based Approach system, and it lets a foreign firm take part in construction planning, execution, and supervision in the country.
A BUJKA is built for large firms and large work. It may only take on projects that are high-value, high-risk, or highly technical, while smaller and simpler projects are reserved for local construction companies. Its parent must be a legal entity in its home country with a large business qualification, meaning a substantial net worth and a track record of major projects.
Certifications come first, the office follows.
Both ordinary business activity and construction work.
Bring in foreign experts and Indonesian staff, and sponsor work permits for foreign employees.
Run the office banking and administration it needs to operate in Indonesia.
Contact companies and institutions, collect information on available projects, and build contacts.
Take part in bidding for projects, including before a local partner is confirmed.
A BUJKA does not build alone.
The reservation of smaller projects for local firms is deliberate. A BUJKA is meant to bring scale, technology, and expertise to complex Indonesian projects, working alongside a domestic partner rather than competing for routine work. Choosing the right BUJK partner, and structuring the joint operation, is as important as the license itself.
Certification, license, then tax.
We check your project plans and confirm your parent meets the large qualification a BUJKA requires.
We arrange the Business Entity Certificate and Work Competency Certificates through an accredited LSBU.
We register the office through OSS-RBA and obtain your NIB and construction standard certificate.
We register your NPWP so the office can operate, hire, and pursue projects.
Indicative, since certification drives the clock.
| Step | Indicative time |
|---|---|
| SBU and SKK certification | Several weeks |
| NIB and construction standard certificate (OSS) | A few working days |
| Tax registration (NPWP) | A few working days |
| Total | around 4 to 6 weeks |
The construction standard certificate runs for three years and is renewable. Timelines depend most on assembling the certification documents and the association membership.
Indonesia recognizes several representative offices, each tied to a different kind of parent company. Two niche types also exist: KP3A PMSE for foreign e-commerce, and KPJPTLA for electricity support services.
The general representative office for liaison, coordination, and market research before you commit to a company.
KPPA officeThe representative office for a foreign trading company, acting as your selling, buying, or manufacturing agent.
KP3A officeA foreign-owned company, the vehicle for earning revenue, invoicing, and selling in Indonesia.
Company registrationWhat foreign companies ask most.
A BUJKA, Badan Usaha Jasa Konstruksi Asing, is the representative office a foreign construction services company opens in Indonesia. It lets a large foreign firm take part in major construction projects, governed by Government Regulation 5/2021.
A BUJKA needs a Business Entity Certificate (SBU) and Work Competency Certificates (SKK), assessed through an accredited LSBU and registered through OSS, plus membership of an Indonesian construction association. SKK replaced the older SKA after the 2021 construction reforms.
No. A BUJKA executes work through a joint operation with a local construction company (BUJK), which must be Indonesian-owned. It can, however, bid for projects before a partner is confirmed.
Only large, high-value, high-risk, or highly technical projects. Smaller and simpler projects are reserved for local construction companies.
There is no PT PMA-style paid-up capital, but the parent must meet a large business qualification, with net-worth and experience thresholds for its classification.
Around four to six weeks in most cases. The certification stage drives the timeline, while the OSS license and tax registration are quicker once the certificates are in place.
