Attestation of a site engineer and scope of the construction licence
A private Belarusian company has a licence for general contracting of residential buildings up to 5 storeys. It wins a tender for a 4-storey residential block with an attached 1-storey commercial annex and an underground car park for 40 cars. The annex is built on a separate foundation with a movement joint. The client asks the contractor to also install the internal gas supply to the annex and the fire-automatic system. The contractor signs a supplementary agreement and subcontracted the gas works to a firm whose licence covers only gas distribution networks, not internal gas installations. During the first inspection the technical supervision engineer notes that the car park is below the groundwater table and that dewatering was not in the approved construction organization plan. The site engineer, who has 3 years of experience, signed the as-built documentation for the annex.
1. Does the contractor's licence cover all the works it accepted? Identify which works fall outside the licence and what the lawful route is.
Read the worked answer
The licence is limited to general contracting of residential buildings up to 5 storeys, so each element must be checked against its own scope rather than the overall building height.
The 4-storey residential part is within the declared scope. The annex and the underground car park are separate structures with their own foundations and a movement joint; the car park is a structure of a different class and purpose, so the licence's residential-building wording does not automatically extend to it. The internal gas installation is a separate licensed activity, and the subcontractor's licence for distribution networks does not cover internal gas installations inside a building, so that subcontract is invalid for this scope. The fire-automatic system is likewise a specialised licensed activity.
Lawful route: the contractor must either obtain the missing licence entries (or bring in a licensed subcontractor whose licence expressly covers internal gas installations and fire-automatic systems) before performing those works, and amend the contract to reflect the change of performer. Works performed outside the licence are not lawful and cannot be accepted as compliant as-built. The site engineer's signature on as-built documentation for the annex is also questionable because the annex is outside the licensed scope and because attestation requirements for signing as-built documentation depend on the engineer's certification.
2. The dewatering omission is discovered after excavation. What should the site engineer do, and who bears the consequences?
Read the worked answer
The construction organization plan (COP) is the governing document for the sequence and methods of work, and dewatering below the groundwater table is a mandatory element of it. Once the omission is found, work in the affected excavation must stop until a revised COP section for dewatering is developed, agreed with the designer if it affects the design, and approved by the client and the technical supervision engineer.
Responsibility is distributed: the contractor is responsible for developing and following the COP and for the unauthorized deviation; the technical supervision engineer is responsible for having approved a COP that did not address known hydrogeological conditions; the designer is responsible if the dewatering scheme affects structural or waterproofing design. The client bears the cost of the additional works if the need arose from incomplete initial data it supplied, but not if the data were adequate and the contractor simply failed to plan. The site engineer should record the situation in the site log, notify the client and supervision in writing, and not sign any as-built documents for the car park until the dewatering and waterproofing are completed and verified.
