The architectural design concerns the construction of a new 34-bed Renal Dialysis Unit, on a plot of 11,797,57 sq. m., located in  Yfantes  Area of ​​Komotini Municipality, on the Komotini – Iasmos- Xanthi Provincial Road.

The main objectives of the design were the integration of the building to the size and shape of the plot, the compliance with regulations, technical specifications and the building program, the functionality in the organization of the various functions, the dynamic and contemporary aesthetic approach compatible with the use of the building as a health care facility and the independent access for service facilities.

Due to the size and shape of the plot, an elongated ground floor building of 1,178 sq. m. was designed, which is located parallel to the Provincial Road in the middle of the plot.

The internal arrangement is organized into three groups: reception areas, patient areas and facilities and ancillary areas. Reception and administration areas are arranged at the east end of the building, which corresponds to the location of the entrance to the plot, two 16-bed dialysis rooms are centrally located, each with support areas, while MEP areas, storages and  ancillary areas are placed at the west side of the building. The building has an indoor planted patio in combination with the waiting area, which brings natural light inside and creates a pleasant environment for staying during the summer period.

The central entrance is located on the south side facing the Provincial Road and includes a sheltered drop-off area.

The clear and comprehensible layout of the floor plan is the key component of the facades. Thus the facades of the building are organized on the basis of the simplicity and geometrical clarity of the volumes combined with the functional layout of the openings and sun protection elements. The aim of the proposal is to split the volume of the building and create four distinct volumes, which are emphasized both in ground level and in height, giving a dynamism to volume formation and emphasizing the public character of the building. The different aesthetic approach and the individual architectural interventions in the protruding volumes, such as the creation of a boxing frames for the openings, emphasize their importance and enhance the variety of facades.

Access to the plot is by the Provincial Road with a proper traffic connection configuration, in accordance with the regulations.

The landscape of the surrounding area includes 58 parking spaces (1 ambulance) on the east side of the building, an internal road network for servicing the building, pedestrian access and disabled access. Extensive green areas in front, behind and on the east side of the building are also provided, as well as in the perimeter of the internal road.

Road viaducts carrying two independent branches of motorway, with a total length of 350m, a width of 14,2m each, and a maximum pier height of 58m. Continuous superstructures of prestressed concrete single-cell box girder of variable depth, rigidly connected to the piers, constructed with the balanced cantilever method. Bridge piers are founded on cylindrical shafts.

In the context of the upgrading of the Northern Crete Road Axis (BOAK), Bridge G4 from CH.5 + 710.99 to CH.6 + 150.00 (Gournes – Hersonissos section, Heraklion Prefecture) was recently constructed and delivered to traffic. METE SYSM prepared the final study of the project and provided support to the Contracting Consortium during its construction. After completion of the bridge, the construction company participated with it in the Concrete Awards 2019, the first awards created to highlight the excellence in concrete projects, in terms of design and construction level, but also functionality, originality, environmental protection, satisfaction of the end customers and users of these projects. Bridge G4 was distinguished by winning the silver award in the Infrastructure Works Section/Subsection: Bridges and Tunnels.
The bridge superstructure is continuous with five spans (total lengh 440,0m on the bridge axis) made of cast in-situ prestressed concrete. The balanced cantilever method was used for the construction with 3,5 to 5,0m long segments. A camber design study to support the contractor at every construction stage was also prepared.
In plan, the bridge alignment moves along a circular arc with a radius of 900m and a straight line after the corresponding transition curve. In elevation, the red line moves in a straight ascending section with a slope of 4,27%, at a height from the natural terrain, ranging from 5,0 to 31,0m, and mostly between 20,0 and 28,0m in the central part of the bridge. The clear heights of the piers are 15,0m, 20,5m and 22,0m . The outermost piers have a twin blade (rectangular) cross section while the central piers have a rectangular hollow section with external dimensions of 4,0×6,5 m. Piers are founded on pile caps.
The single box-shaped cross-section has a height which varies parabolically in elevation, ranging from 3,0m in the central span region to 6,5m in the pier supports. The total width is 13,75m carrying one-way traffic of the right branch of the highway with 2 traffic and 1 emergency lane and sidewalks on both edges. Safety barriers, street lighting poles, insulation of the deck with a special membrane and drainage of the deck with longitudinal and vertical drainage pipes are also provided.
The superstructure is monolithically connected to the four piers, resting on sliding bearings (vertical) along with shear keys (transverse horizontal) at the abutments, forming a case of semi-integral bridge with satisfactory behavior for both vertical as well as horizontal loads, with expansion joints and bearings only at the abutments and with reasonable displacements.
