Task
Safe, efficient and quick dismantling

Construction company “Forest-Ukraine” – in 2021 we successfully dismantled the chimney at the “Mykolaivcement” enterprise.

In addition to the construction of residential buildings and structures, we have long specialized in dismantling buildings and industrial facilities throughout Ukraine – both in large cities – Kyiv, Dnipro, Odesa, Lviv, and cities and towns of regional significance – Lutsk, Rivne, Ivano-Frankivsk.

The prices for dismantling work in the price list fully satisfied the customer. It was a separate building without technological equipment, which had long been out of operation. The enterprise’s clinker kilns were stopped back in 2014 (before that, they worked using an outdated energy-intensive wet method). Cement began to be produced from clinker.

The work on dismantling the pipe was carried out as planned, in accordance with the current safety regulations of Ukraine and international standards of CRH. Dismantling of structures of this type is faced with a large number of organizational and technical measures related to the safety and complexity of the demolition work.

The equipment involved – excavators and dump trucks, bulldozers and tractors, as well as the involved demolition specialists – completed this responsible and difficult task qualitatively and on time.

It was decided to carry out the demolition of the chimney by blasting – this required the involvement of explosives engineers.

In the identified weak points of the structure of the 30-meter concrete pipe, more than 100 holes were drilled for dynamite bombs.

Safety and safety again: working with dynamite is no joke.

Explosives with electric detonators were laid and the blast was carried out.

No unplanned or emergency situations! No nearby buildings were damaged. The pipe fell neatly and precisely into the planned sector, after which it was disassembled into its component parts by special equipment and crushed into smaller fractions by a jaw crusher.

An emergency dangerous structure is no longer a problem for the enterprise.

A giant structure made of metal and concrete falls into the planned place.

A satisfied customer is the best reward for a quality job!

    Frequently asked questions

    What is needed to calculate the cost of dismantling?

    To accurately calculate the cost, we need to obtain basic information about the object. In most cases, it is enough:

    photo of the building from the outside (from all sides) and from the inside
    technical passport or project (if available)
    height of the building and number of floors
    type of foundations (monolithic, prefabricated, pile, etc.)
    approximate distance of transportation of construction waste

    The more complete the initial information, the more accurate the calculation.
    In more complex cases, we go to the object to inspect and prepare a detailed estimate.

    What is more profitable: complete dismantling or partial dismantling with preservation of structures?

    In practice, dismantling with preservation of structures almost always turns out to be more expensive.

    This is due to the fact that:

    a significant part of the work is performed manually, without the use of heavy machinery

    the execution time increases

    the risks for workers and structures increase

    In addition, most used materials already have a significant degree of wear or have exhausted their resource, so their further use or sale is not always economically feasible.

    In many cases, complete dismantling with subsequent processing of materials (for example, into secondary crushed stone) is a more profitable and safe solution.

    What to do with construction waste after dismantling?

    During dismantling, we immediately perform rough sorting of materials:

    metal is separated and sent for recycling
    concrete, brick and other mineral materials – separately
    wood, plastic and other waste – separately

    Furthermore, several options are possible:

    Transportation to a landfill – a standard solution, but involves additional costs for disposal
    Recycling of materials – we crush part of the concrete and brick into secondary crushed stone, which:
    is used for backfilling, roads, preparation of foundations
    can be implemented

    We help you choose the best option to minimize the client’s costs.

    Do you dismantle buildings damaged by hostilities?

    Yes, we have experience in performing dismantling work on objects damaged as a result of war.

    Such objects require a particularly careful approach, as they often have:

    emergency and unstable structures

    partial collapses

    increased level of danger for personnel

    Before starting work, we necessarily conduct an inspection, assess the technical condition of the building and develop a safe dismantling technology.

    If necessary, we provide:

    development of a PVR in a short time

    phased dismantling with risk minimization

    sorting and removal of construction waste

    We work throughout the territory of Ukraine (except for zones of active hostilities) and are ready to respond promptly to such objects.

    Is a project (PVR) needed for the dismantling of a building?

    Yes, in most cases, the implementation of dismantling works requires the development of a work execution project (PVR).

    We develop PVR in a short time – usually within 2-3 working days.
    The document takes into account the dismantling technology, safety, sequence of work and organizational solutions.

    Our company provides full support:

    preparation of all necessary documentation
    maintenance of executive documentation
    work with VAT and official closing of volumes

    That is, the client receives not only work, but a completely closed process in terms of documents and reporting.

    Do you work throughout Ukraine?

    Yes, we perform dismantling work throughout the territory of Ukraine, except for regions where active hostilities are ongoing.

    We have our own fleet of machinery and equipment, which allows us to quickly:

    mobilize a team

    relocate equipment

    start work in a short time

    Thanks to this, we work effectively both on local sites and on large projects in different regions of the country.
