Piling often necessitates a completed piling to be trimmed to an exact cut-off level to support the pile caps, rafts, foundations and structural connections. This work should not cause unnecessary damage to the reinforcement, the rest of the pile shaft or the surrounding work area, but must remove unwanted concrete.
Best International Contracting Company offers its services in terms of pile breaking to Saudi Arabia contractors, developers and project teams that require its services to have controlled pile-head removal of construction and industrial sites that are suitable. The types of piles, diameter, cut-off level, reinforcement, concrete condition, access, quantity, sequence and disposal responsibility are reviewed and then the work is proposed.
The service is geared towards cutting and shaving off finely completed pile head of concrete to the desired requirement. Pile installation, foundation construction, structural design, integrity testing and repair of concrete are not part of the accepted contract unless they are actually covered by the accepted contract.
Pile breaking, a transitional activity, is between piling and foundation construction. The completed pile should be designed in such a way that the next pile top, raft or structural connection should be started on a sound and properly located interface.
The cut-off level, pile schedule, structural details and method requirements that have been approved by the project should be issued before work commences. The break line must be set in a consistent and accurate location across the workfront and this is achieved by having control over the survey.
Being a pile head breaking contractor KSA project teams can take the approach of defining packages, BIC determines the sequence around excavation preparedness, access, lifting requirements, protection around reinforcement, removal of debris, inspection and liberation to the next activity.
Hydraulic Pile Breaking
The hydraulic pile breakers are based on modules or jaws that are linked together and organized around the pile to apply force and break the concrete at the desired level. It is applicable in areas with the right geometry of the pile and conditions of the site to enhance consistency and minimize long-term handheld breaking.
In the case of hydraulic pile breaking Saudi Arabia projects, the breaker size required, carrier equipment, lifting setup, access width, the spacing and cut off sequence of the piles are checked prior to mobilisation. The equipment has to be suitable with the diameter of the pile, as well as the reinforcement design.
Hydraulic breaking does not eliminate the preparation and final trimming. The concrete in the immediate vicinity of reinforcement or and the final surface could still need controlled manual finishing.
Manual Pile Breaking
Manual breaking involves hand tools and controlled demolition techniques in which the access, size of the pile, reinforcement congestion, amount or project constraints make special hydraulic equipment ineffective.
The work must be done in stages planned and not by haphazard shock. Operators expose the reinforcement very cautiously, eliminate the concrete gradually and do not damage much below the cut off limit approved.
Final preparation may also be by manual work when a hydraulic break is used or with piles which have to be trimmed off selectively around bars which are very close together.
Jack-Hammer Pile Breaking
Appropriate pile heads, local trimming and removing of concrete may be performed using handheld pneumatic or electric breakers. The tool size chosen must be appropriate to the geometry of the pile, and the degree of control needed.
BIC compares jack hammer pile breaking KSA requirements with the working space, vibration issues, reinforcement, concrete strength, operator access and control of debris. Big tools that are not handled carefully may cause harm to the rest of the pile, and should not be considered an alternative to a certified technique.
Saw-Cut and Controlled Break Lines
A perimeter saw cut or other specified and appropriate controlled break line can be established to assist in defining the upper removal area where indicated and appropriate. Planning of the depth should ensure that the reinforcement and retained pile is not damaged.
Reducing requirements, controls of dust or slurry, power supply and disposal of power and slurry arrangements should be agreed upon prior to the commencement of the work. A saw cut is not sufficient to be the final step in preparing the pile, the rest of the concrete has to be removed and finished.
Final Trimming and Surface Preparation
Once the main concrete section has been stripped out, the rest of the pile head can have to be trimmed to the acceptable height, loose concrete can be removed and the interface prepared to be inspected.
The project should indicate the condition required. BIC offers the ready pile head to be reviewed but does not approve the structural suitability or pile integrity on its own.
Reinforcement Exposure and Protection
Continuous reinforcement of piles up to the pile cap or foundation should not be covered without undue bending, cutting or impact. The approved structural information should be checked prior to setting up the bar, which needs to be projected and allowed tolerance.
The loose concrete is removed off bars as per the scope and site damage avoided after being exposed. The straightening, replacement and welding or alteration of reinforcement is not done without approved technical direction.
Service boundary: On this page, the controlled pile-head breaking, trimming and preparation will be discussed. Under their relevant services are the installation of piles, testing of piles, excavation of large masses, dewatering and installation of foundation concrete, reinforcement fixing, repairing of a structure and overall demolition. Any repair which is less than the approved cut-off level needs individual engineering guidance.
The geometry of piles, the strength of concrete and reinforcement density and accessibility of the reinforcement influence the breaking method selected. An efficient technique applied to open and regularly spaced piles might fail to be effective in pile groups which are crowded, limited in headroom or working next to completed structures.
We have the concrete pile breaking services Saudi Arabia scope that is subject to planning of appropriate bored piles, cast-in-place piles and other reinforced concrete pile heads where the project furnishes the information required about the structural and cut-off.
Piles with odd piles systems, piles that are in very bad condition, piles that are steel cased, piles having a post tensioning element or beyond the conditions mentioned in the issued information must have a separate technical review prior to the work being continued.
Some of the projects that may be considered as Jubail include residential buildings, utility buildings, utility equipment foundations, warehouses, infrastructure and plant expansion construction. Pile breaking activities in these conditions usually require the coordination with the excavation, permission of the access, operating conditions, lifting paths and then foundation works.
BIC reviews One of the projects teams that Jubail project can involve to work on the defined amount of piles and site conditions is a pile breaking contractor. The work will be scheduled based on the approved method statement, workfront release and survey reference, inspection sequence and required completion programme.
In situations where the site is still in operation, it might be necessary to further isolate the working areas, as well as managing dust, coordinating noise and staging construction. Pre-mobilisation these needs are supposed to be identified.
The cut-off level is a critical reference which is approved. Too high and too low breaking may impede the construction of the foundation, and too low breaking may impact the retained pile, resulting in more work to repair.
Accepted benchmarks and a pile schedule should be provided by the customer. The points of the survey or level which can be seen must be preserved in excavation and breaking. All doubts about datum, drawing revision or pile identifying must be made out prior to the removal of concrete.
Land survey work is done under the Land Survey Services page. The survey assistance as part of a pile-breaking proposal is only covered by the specified setting-out and level checks mentioned in the scope.
Pile head and its environs must be stable and open. Excavation must reveal sufficient amount of the pile to the approved equipment and methodology of working without leaving the people and machinery in a hazardous situation.
The Pile diameter, spacing, observable damages, the location of reinforcement, the condition of concrete, the water under the ground, the buildings and the accessibility of lifting or carrier machines are checked and the production starts.
When a pile is observed to be broken, displaced, large-honeycombed or otherwise not as per the information being circulated, then it must be noted and reported to the concerned engineer before further breakage.
The hydraulic equipment may be appropriate where the volumes of production, frequent geometry of piles and access warrants mobilisation. Manual processes might be more economical with smaller volumes, limited areas, reinforcements or final finishing that is intricate.
The approach that is chosen can be a mixture of the two. The main pile-head section can be removed using hydraulic equipment, then the bars should be handled manually and the final interface.
The choice of the methods is determined by the conditions of the site and the allowed requirements of the project. BIC is not one of these methods that are universally applicable to all piles or foundations.
Fragments of piles may result in large pieces of concrete, smaller pieces and bare metal. The method statement must recognize the means which will be used to lift large parts, the location of the debris and the transportation and disposal.
Prior to production, lifting points, excavator or crane access, skip points and haul routes must be coordinated. Sections that are removed should not be left to fall on other piles, the reinforcement or work done.
Recycling of concrete, offsite disposal and general waste services will only be included upon mentioning in the accepted proposal.
Pile head is broken, trimmed and cleaned to be inspected. The review can take into account the last level, the concrete state, that is visible defects, the exposure of reinforcement and preparedness of the next foundation activity.
The accepted structural and project documents should be the source of the acceptance criteria. The contractor logs observable conditions, and discusses minor preparation details in scope.
Concrete loss below the cut-off level, significant damage, damaged reinforcement or suspected pile defects should be assessed by the engineers and an accepted repair or disposition must be made before any further work is conducted.
Pile breaking entails heavy concrete, powered equipment, hydraulic equipment, lifting work and sharp reinforcement and work in excavated spaces. The workfront needs to be designed in such a way that does not put personnel in the path of falling or suspended areas.
Examples of controls are the access to the excavations, stable working platforms, equipment exclusion zone, lifting plans, dust suppression, eye and hearing protection, reinforcement caps, lighting, and controlled debris removal.
The risk assessment and method statement of the site should be based on the real equipment, excavation depth, piles placement and activities around the excavation. The work must cease when the access, ground support conditions or lifting conditions are unsafe.

BIC does not consider pile breaking a normal demolition activity of concrete but rather a controlled structural- interface activity. We check cut-off levels, reinforcement, access and lifting, inspection and the following stage of construction and certify the work method.
We can coordinate the pile-breaking workfront with construction around us with our civil contracting, equipment and manpower capabilities. This will only have supporting services which are clearly indicated in the proposal.
We establish limits between the pile breaking, piling, foundation construction, surveying and structural repair such that the roles are well defined all through the project.
Pile-breaking questions may be examined to fit in the appropriate projects in Saudi Arabia. BIC serves the needs of Jubail, Dammam, Khobar and the entire Eastern Province, and Riyadh and Jeddah project can be evaluated based on the size of the piles, technique, equipment mobilisation, access, disposal and programme.
BIC is able to study hydraulic, manual, jack hammer and combination techniques of appropriate reinforced concrete pile heads.
Customer offers authorised structural information and project survey control. The check and the level are marked and checked prior to breaking.
The continuation of reinforcement is cautiously continued under the acceptable procedure. Any cutting, bending or repair must be under approved technical guidance.
No. It depends on the suitability of the piles on the basis of the diameter of the piles, geometry, reinforcement, spacing, access and equipment needs.
Yes. Small volumes, crowded areas, and restricted access and final trimming can be inspected with manual procedures.
No. Pile installation, integrity testing and load testing are independent specialist works except where parts of an otherwise contract.
The proposal assigns the following duties lifting, loading, on-site movement, recycling and off-site disposal.
The situation is documented and is sent to the concerned engineer. The approval of a technical decision is needed to repair or accept.
Appropriate work can be checked where the permit, access, noise, dust, and lifting are well established, exclusion areas and operational limitations.
