Engineering our own solutions for a stronger future.

We are proud to announce an important milestone for Omikron Kappa Consulting S.A.: the internal release of the first four applications of our new EasyCalc / ProCalc engineering software platform, developed entirely in-house by our engineering team.

Our first release includes EasyCalc Pile, for axially loaded bored piles and pile-group analysis; EasyCalc Shallow Foundations, integrating bearing capacity, settlements and reinforced-concrete footing checks; EasyCalc Wall,
combining retaining-wall geotechnical and structural design; and ProCalc FEM – Shallow Foundations, our 2D finite-element platform for layered soil and nonlinear soil–structure response.

For us, developing engineering software is much more than automating calculations. It is about transforming our engineering knowledge, experience and design philosophy into tools that we fully understand, control and
continuously improve.

When engineers develop the tools they use to solve real engineering problems, the calculation process becomes more transparent and auditable. Assumptions remain visible. Different design approaches can be compared more efficiently. Repetitive calculations can be automated, while engineers can dedicate more time to
interpretation, verification and engineering judgement.

Most importantly, the knowledge gained from every project can progressively become part of the company's own engineering infrastructure.

This is why we see in-house software development as a long-term investment in Omikron Kappa's technical capability.

And this is only the beginning. Additional applications will be progressively introduced.

Our ambition is to create an integrated software ecosystem that grows together with our engineers, our projects and our technical experience — connecting analytical design, numerical modelling, verification and automated engineering reporting within a common environment.

Built by engineers.
Tested through engineering.
Developed for real engineering challenges.

More to come soon.

Structural retrofitting and redevelopment of existing and abandoned hotel complex

HELIOS Hotel Complex in Agia Marina, Attica

Approx. 34,550 m2 with 28 existing buildings across three plots.

Working with an existing development of such a magnitude involves dealing with decades of history embedded in the structures: existing geometry, materials, reinforcement detailing, deterioration and challenging coastal environmental conditions.

Omikron Kappa Consulting SA design scope covers complete structural engineering lifecycle — from detailed structural mapping and pathology assessment and advanced seismic analysis, to the design of targeted strengthening and rehabilitation interventions.

The scope also extends to the geotechnical and structural design of new structures and facilities, including swimming pools, water reservoirs, a wastewater treatment plant and retaining structures, supported by BIM-based interdisciplinary coordination and construction supervision.

A challenging project where mapping, analysis, rehabilitation and new design come together to give an existing development a new future.

Omikron Kappa Consulting is proud to celebrate the commissioning of the “Thessaloniki Metro Extension to Kalamaria”. A flagship infrastructure project and a significant milestone in the continued development of Thessaloniki’s urban transport network.
As a Lead Designer, Omikron Kappa ConsultingSA has been involved in the project since the tendering phase, contributing throughout the development of the General and Detailed Designs for key elements of the metro extension to Kalamaria, including the two single-track TBM tunnels (7km), Mikra Station complex, forestation and other major design elements.
Heartfelt congratulations to all those involved in the project, from Elliniko Metro and the Greek State to every engineer, designer, specialist and member of the project whose dedication and expertise made this milestone possible. We are proud to have contributed to a project that will shape the future of mobility in Thessaloniki and have a lasting impact on the city and its communities.
Another landmark project. Another milestone delivered.

Cut & Cover – Lane Cover structures are considered an optimum restoration solution, particularly where road alignments pass through areas of deep excavations.

These structures are constructed by excavating the required area, implementing temporary support measures where necessary, constructing the permanent structure, and subsequently backfilling above and alongside it in accordance with the design.

The following aspects should be considered during the design and dimensioning of these structures:

1. Compliance with the Required Environmental Conditions

Environmental requirements significantly affect the geometry of the structure, structural thicknesses, and the height of the backfill above it, such as maintaining a free excavation height above the final backfill level of less than 25m.

2. Maintenance of Traffic During Construction

Maintaining traffic on the existing roadway is an important design consideration. The construction sequence should therefore be incorporated into the detailed design, including concrete construction joints, reinforcement continuity and lap lengths, available working space, and successive traffic diversion stages.

3. Type of Foundation – Shallow or Deep Foundation (Piles)

The foundation system is selected based on the geotechnical conditions of the area. Where one side of the structure is adjacent to an excavation slope and the opposite side borders steep downhill terrain, a deep foundation system using piles should be investigated.

Special attention is also required in critical local areas not fully covered by the structural model. These areas may require additional reinforcement to resist bursting forces, as illustrated in the following images.

Building a state-of-the-art waste treatment facility on 80 m of uncompacted mine waste?

Here is how geotechnical engineering overcame extreme soil uncertainty.

The Mechanical and Biological Treatment (MBT) Plant in Ptolemaida was built on a site consisting of waste deposits from open-cast lignite mining activities. Beneath the surface lay 60–80 meters of heterogeneous, randomly deposited fill—a chaotic mix of marls, clays, sands, and gravels.

To address severe risks of differential and long-term creep settlement, an integrated ground improvement strategy was implemented, combining surcharge preloading with deep prefabricated vertical drains (PVDs).

A comprehensive geotechnical monitoring program was implemented throughout the preloading process. High-precision settlement markers and vibrating-wire piezometers provided continuous data on ground movement and pore-water pressure development. The monitoring data was then back-analyzed to calibrate numerical geotechnical models, verify design assumptions, and assess the overall effectiveness of the ground improvement works.

The result? A resilient, structurally sound foundation built efficiently on highly problematic ground.

Swipe through the carousel to see the site conditions, engineering ex*****on, and monitoring data step-by-step.

Some of the most demanding engineering projects are defined not only by what is built, but also by the precision required to protect everything around them.

Santacruz Station, part of Mumbai Metro Line 3 in India, is a compelling example.
The project combines a deep cut-and-cover station box with a parallel wide NATM platform tunnel, constructed through a carefully coordinated sequence of TBM and NATM works within a highly constrained urban environment.

As lead designer for the geotechnical works, Omikron Kappa developed the temporary retaining structures and tunnel solutions required to control excavation-induced movements, manage groundwater and safeguard critical surrounding infrastructure, including the Vakola Flyover and a 2,400 mm water main.

Now fully operational, Santacruz Station demonstrates how advanced analysis, multidisciplinary coordination and risk-based design can transform complex underground constraints into safe, resilient and functional infrastructure for the city.
