STR 1.06.01:2016 – Lithuania Regulation for Construction Works and Technical Supervision
The Statybos techninis reglamentas STR 1.06.01:2016, titled Statybos darbai. Statinio statybos priežiūra (Construction Works. Supervision of Building Construction), is a binding technical regulation issued by the Ministry of Environment of the Republic of Lithuania. It operates under the framework of the Law on Construction and applies to new construction, reconstruction, major and minor repairs, and demolition projects. This consolidated version includes amendments valid through May 2025, specifically integrating requirements for the electronic construction log and updated standards for building material compliance.
The regulation governs the organizational sequence of construction, the status and responsibilities of key personnel, and mandatory documentation procedures. It is structured into eight primary chapters covering general provisions, references, terminology, and specialized sections for construction management (IV Skyrius), earthworks (V Skyrius), project execution supervision (VI Skyrius), and technical supervision (VII Skyrius). The document also contains five annexes, including the fields of construction activities, the use of FIDIC contract forms, and the specific structure of the Construction Log (Statybos darbų žurnalas).
Key technical elements detailed in the regulation include procedures for works within the protection zones of infrastructure, requirements for building conservation during work suspension, and specialized supervision protocols for the modernization of multi-apartment residential buildings. It defines the hierarchical relationship between the Site Manager (statinio statybos vadovas), Technical Supervisor (statinio statybos techninis prižiūrėtojas), and the Project Execution Supervisor (statinio projekto vykdymo priežiūros vadovas).
Mandatory Documentation for Commencing Works
According to Section 5, construction works may only begin once the developer has notified the authorities and provided the following documents to the contractor and technical supervisor:
- Construction Permit: Validated documentation or its issuance date and number.
- Approved Project: The technical design or specialized project for heritage sites.
- Site Handover Act: The signed document transferring the construction site from the developer to the contractor.
- Utility Connection Conditions: Special requirements for temporary connections to energy, water, and communications networks.
- Construction Log: A mandatory register, which must be in electronic format for exceptional buildings and state-funded projects.
Regulations for Earthworks (Žemės darbai)
Chapter V establishes strict protocols for earthworks, particularly in areas with special land-use conditions or near existing infrastructure:
- Notification Period: Utility owners must be notified at least 5 working days prior to the start of excavation.
- Work in Road Zones: Excavation on roads or in their protection zones requires written consent from the road owner and coordinated traffic regulation measures.
- Archaeological Oversight: If unexpected structures or archaeological heritage are discovered, works must stop immediately, and the Department of Cultural Heritage must be informed.
- Winter Restrictions: Demolition of road pavement structures is generally prohibited from December 1st to April 15th, except for repairs or reconstruction.
Supervision Roles and Hierarchy
The regulation distinguishes between three primary supervisory roles that ensure quality and compliance throughout the project lifecycle:
- Site Manager (Statinio statybos vadovas): Represents the contractor, manages the daily technical process, and is responsible for the normative quality of the building.
- Technical Supervisor (Statinio statybos techninis prižiūrėtojas): Appointed by the developer to protect the developer's interests and verify that works match the project and quality standards.
- Project Execution Supervisor (Statinio projekto vykdymo priežiūros vadovas): Appointed by the designer to ensure that the actual construction strictly adheres to the architectural and technical design solutions.
Construction Log and Reporting
The Construction Log (Statybos darbų žurnalas) is the primary record of progress. Annex 4 details its mandatory use and the transition to electronic systems:
- Mandatory Electronic Log: Required for new construction, reconstruction, and demolition of exceptional and non-exceptional buildings.
- Daily Entries: Records of works performed, materials used (including certificates of performance), and weather conditions must be made daily.
- Inspection Records: All supervisors must log their findings, identified defects, and instructions for correction directly into the log.
- Data Integrity: The developer must ensure access to the log for state inspectors and all construction participants.
Frequently Asked Questions
When is project execution supervision mandatory according to STR 1.06.01:2016?
Supervision is mandatory for the construction of exceptional buildings and any buildings (exceptional, non-exceptional, or simple) located within protected territories.
Can the Site Manager also serve as the Technical Supervisor?
No. The regulation prohibits the technical supervisor from having any contractual relationship with the contractor or being employed by the contractor's company to ensure independent oversight.
What is the procedure if construction is suspended for more than 3 months?
Building conservation procedures must be initiated. The developer must organize a conservation project or description and complete the necessary works within 30 days to protect structures and ensure site safety.
How long must the developer keep the Construction Log after completion?
The developer must preserve the paper or electronic log and all official supplements until the building is sold to a new owner or until its deregistration from the Real Estate Register.
What is required for earthworks in a railway protection zone?
Works may only proceed in the presence of an authorized representative of the railway infrastructure manager and after obtaining written consent and signing a utility installation agreement.
Who is responsible for correcting project design errors found during construction?
The Site Manager must notify the Technical Supervisor, who then coordinates with the Project Designer to require a correction of the project solutions.
