Foundation Inspections

When the conditions of a foundation is unknown, an Allnamics Foundation Inspection will help you to determine the status of the foundation of your property.
Based on our experience, we can advice on the required actions for keeping the foundation in shape for the next coming decennia.

Predictions of pile driving

Pile Driving Predictions are made to predict the pile, soil and pile driving hammer behaviour during installation of foundation piles as well as large diameter monopiles. By doing this in advance, during the engineering stage, troubles during installation can be avoided. Is the pile driving hammer heavy enough, does it deliver enough energy to install the pile to its designed penetration depth? Are the pile stresses during installation acceptable? And are the stresses in the monopile during installation not to high, leading to unacceptable fatigue level?
By making a Pile Driving Predictions using the AllWave-PDP software , answers on these type of questions can be generated by simulating the pile, soil and hammer. For sheet walls, foundation piles, offshore piles and wind farm monopiles.

Predictions Vibratory Hammer – VPD

Like the Pile Driving Predictions for impacts hammers (PDP), simulations can be made for piles installed by means of a vibratory hammer. Comparable results as with the PDP, one can study the efficiency of a vibratory hammer, its maximum penetration or refusal level, the maximum stresses and the amount of fatigue. Using the AllWave-VDP software and a large database of predicted and measured results, leads to reliable prediction results.

Sheet Wall Design

One of our specialisations is the design and calculations of sheet wall and retaining wall constructions, both temporary and permanent structures.

Calculations can be made for both its final stage as well for installation (Vibratory Driving Prediction).

Second opinion and construction disputes

As a specialist on the field of pile testing and geotechnical designs, Allnamics can assist you at the design of all geotechnical structures, as well being you partner in foundations design.

Led by the experience of many years, the experts of Allnamics are able to advise and assist you in court processes.

Site design

Site conditions can be easy or severe. At any time, the soil resistance at site should be able to resist the loads. Loads during installing the piles, and at working conditions. Allnamics can help you, based on many years of experience of pile testing, pile design revisions, etc.

Monitoring and prediction of vibrations

Building activities lead to vibrations on the building site. Either the building traffic delivering new products, or the crane leads to vibrations in the soil and nearby buildings.
Neighbours will certainly be sensitive for these type of vibrations. Therefore Allnamics has developed a prediction model to predict the level of the vibrations due to pile driving activities. Will it be nuisance, damage or just feeling the vibrations. It is our expertise to determine whether it is allowable or not.

Monitoring vibrations

Allnamics owns several types of sets with sensors and data acquisition units to monitor the vibration levels of structures and buildings. Depending on its application, these measurements can be controlled by staff on the building site or automatic. In automatic mode, when a prescribed level is exceeded, the monitoring system alarms the monitoring engineer, client of piling contractor about the vibration levels, so they can undertake actions to limit these vibrations.

Geotechnical Monitoring

Allnamics has developed smart tools, sensors and equipment for the registration and monitoring of all kinds of (geotechnical) parameters, like strain, displacements, settlements, etc.

Pile Damage Assessment

Foundations are the base of constructions. There may not be any doubts about the quality of the foundation and foundation piles.
In case of damage during or after installation, Allnamics can support you with analysing troubles and problems, and propose the solving solution. For instance when:
– Pile damage during driving, broken or damaged pile top
– Broken piles during driving, horizontal cracks in the pile
– Early refusal of driven piles
– Broken cast in situ or bored piles
– And more…
Based on measurements during installation, i.e. during driving (PDM/PDA) the wave pattern in the piles is analysed. As a result, the cause of the damage will be determined, and its solution proposed.
