PROJECT DETAILS

LOCATION:Pristina-Hani I Elezit, Kosovo

OWNER / CLIENT: Ministry of Infrastructure the Government of the Republic of Kosovo

PROJECT DURATION:July 2014-Dec 2020




• Links Kosovo to North Macedonia

• By the end of the project, over 8,4 million person-hours had been reached without a lost time incident.

• More than 22 million direct person-hours had been worked.

• “2016 GRAA (Global Road Achievement Awards) Winner of the Environmental Mitigation category” selected by IRF (International Road Federation)

PROJECT DESCRIPTION

The contract for the Pristina-Hani i Elezit Motorway was signed between the Bechtel-ENKA General Partnership (BEGP) and the Ministry of Infrastructure of the Government of Kosovo in July 2014. The contract was an EPC contract and BEGP was responsible for the engineering, procurement and construction of the overall project.

It was BEGP’s second project in Kosovo. The motorway project is part of the South–East Europe Core Road Network, in which it is referred to as Route 6. The project crosses Kosovo from north to south, linking to Pristina in the north and stretching south as far as Hani i Elezit on the border with North Macedonia. The motorway is expected to have significant strategic and economic benefits. Kosovo is connected to Skopje and has access to Corridor 10, facilitating its trade with the rest of the world. The economic benefits arel not be limited to Kosovo.

The motorway is part of a European network of roads and is expected to contribute to economic integration throughout the region. The project envisaged the construction of 65 km of 2x2 carriageway motorway, designed in three stages. The motorway had been designed in accordance with Trans-European Motorway (TEM) standards as well as Croatian standards, and construction works had been done in accordance with the 2011 general technical requirements (GTR) of the Croatian Road Authority.

UNIQUE CHALLENGES

Alignment of the Route 6 Motorway Section 3 crosses many mountainous terrains and cliffs. Due to the complex geology on the terrain and deeper soil investigation requirements, geotechnical investigations are being carried out with complete attention by a number of teams performing extensive investigations. 19 million m3 of excavation with deepest point 62 m and 11 million m3 of embankments with highest point 24 m were performed during the construction.

ROUTE 6 PRISTINA - HANI I ELEZIT MOTORWAY PROJECT ROUTE 6 PRISTINA - HANI I ELEZIT MOTORWAY PROJECT

13 bridges, totaling 8 km were constructed with 1,777 precast, prestressed, posttensioned and hybrid type of beams. 312 thousand m3 of concrete and 70 thousand meter of piles were placed during the construction of bridges. Due to challenging and mountainous terrain, a 5.75 km meter long Lepence Bridge was constructed along a deep narrow valley accommodating Lepence River and Souther Part of Route 10 Railway Track Line. Design and construction of the bridge including very detailed geotechnical investigation is completed in 18 months.

Due to the complex geology on the terrain and deeper soil investigation requirements, geotechnical investigations, including 16,000 meter of boreholes, were carried out with complete attention by a number of teams performing extensive investigations. 200 thousand meter of active and passive anchors with different thickness of shotcrete works have been performed in order to stabilize deep cut slopes along the alignment.

Climate conditions were of a big concern. During March 2016, despite the heavy rainfall, the project team proceeded with its construction works associated with utility relocation as well as earthworks, structures, drainage, surveying, finishing, and manufacture & operations departments.

Utilities along the project were also one of the challenges. The utility lines had been investigated and identified on site. There existed high voltage lines, power lines and various sewage, water supply and irrigation lines. The design and relocation of some utility crosses underneath the motorway had been completed while others had commenced. 350 utility lines have been relocated and handed over to local authorities and service providers on behalf of the Employer.


ENKA, according to the contract, designed, executed and completed the construction works. ENKA, as the Design/Build Contractor, was responsible for completion of the design in accordance with the required European Standards and Specifications.

The number of direct hire personnel reached 3,353 at its peak, including citizens of 13 different countries, citizens of Kosovo made up 80% of the total. It is one of ENKA’s goals to build a strong quality culture on the project and train the personnel to ensure that quality and safety are part of their everyday activities. Consequently, BEGP had provided all the personnel working on the project with training in safety and quality.

In addition to completed Pristina-Hani I Elezit Motorway, Employer requested to incorporate 2 interchanges and 1 overpass to the BEGP’s scope. At 28 May 2019, Along with the request of the Ministry of Infrastructure and Transport, the term of completion of Contract for construction of Pristina-Hani I Elezit Motorway is extended from 01.06.2019 until 01.12.2020. Concordantly, Employer’s instruction to start the construction activities is expected.

It is the fourth-longest suspension bridge in the world by the length of its central span.

The bridge connects the North Eastern and South Eastern coast of the Izmit Bay, significantly reducing regional travel time. Crossing the bay, the bridge and the connecting highway provides three lanes of traffic in each direction.

Bridge has a total length of 2,682 m with a main span of 1,550 m and having total weight of 52,000 ton.

ENKA SCOPE OF SERVICESScopes of ENKA’s subsidiaries, Çimtaş and Kasktaş, under separate subcontracts are as following:

Çimtaş scope of works:

• ENKA’s fully owned subsidiary Çimtaş has performed Engineering, fabrication, transportation, block formation, trial assembly, fit-up and welding works of girder blocks. Accordingly, Çimtaş Steel (Gemlik Works) and Çimtaş Module and Shipyard (Gölcük Yard) successfully achieved on time completion of the fabrication and ground assembly activities for the Osman Gazi Bridge Project where in total Çimtaş has performed:

• Fabrication of 18,200 tons of tower panels and 33,800 tons of girder panels, thus, completing a total of 52,000 tons welded fabrication.

• Formation and trial assembly of 108 tower blocks comprising of 432 tower panels.

• Delivery of the tower blocks to the erection site by “GMK-1”, a 4,400 DWT dynamic positioning vessel built by Çimtaş Module and Shipyard.

• Formation and trial assembly of 113 girder blocks each with a size of 35mx25mx5m, comprising 3,246 girder panels.

• Combination of the girder blocks on the ground in pairs, to form so called “Mega Blocks”. Under this scope, Çimtaş Steel has transformed 52 girder blocks to 26 Mega Blocks.

• Site erection of the girder blocks where Çimtaş Steel executes the final adjustment and welding works. Within this scope, Çimtaş also performs a part of the girder block shipments via vessel GMK-1.

Kasktaş scope of works:

• At Dry Dock 12,450 m2 water jetted sheet pile driving and extracting works were completed.

• At South Anchorage Block, a total of 14,000 m2 cantilever multi-cell diaphragm wall was successfully executed to enable maximum excavation depth of 16.5 m within an artificial fill for the first time in Turkey.

• A total of 14,700 m2 of diaphragm walls as a box type deep foundation under the South Approach Viaduct (SAV) Footings. The length of South Approach Viaducts is ~1,380 m and founded on 11 no. of footings placed with 125 m of spacing. Height of viaduct footings varies between 13 m to 57 m.

• A soil improvement consisting of 7,500 m of jet grouting under the North Side Span Pier was completed.

UNIQUE CHALLENGES

Çimtaş:

• Total 52,000 tons of steel have been fabricated and delivered on time in 18 months although there have been a considerable amount of design revisions and change requests from the Client.

• In order to compensate the weld shrinkages, steel structure was modelled in 3 different stages in reverse order as installation, trial assembly and fabrication stages.

• All Pre-cambering methods, multi torch welding processes and automated NDT were developed in-house.

• After completion of the block formation works, 52 Girder Blocks have been transformed into 26 “Mega Blocks” in order to reduce the installation time.

• Dynamic Positioning Vessel GMK-1 has been modified in order to transport the “Mega Blocks” to jobsite.

Kasktaş:

• The Osman Gazi Bridge Project is located in one of the most seismically active regions in the world. Since the project alignment intersects with the North Anatolian Fault Line, the design of the structures is of special importance. Especially South Anchorage Block and South Approach Viaducts represent the initials in Turkey in terms of civil engineering.

• South Anchorage Block and South Side Span Pier were designed by enabling rectangular shoring system to work together with multi-cell shoring system and compatible with the shape of integrated structure. The shape of the plan view of the shoring system looks like a guitar. This shoring design is unique not only in Turkey but also in the world.

• Diaphragm walls are implemented as a Box-Type Deep Foundation System under the foundations of South Approach Viaducts. Since the location of the project crosses the North Anatolian Fault Line and it lies within the secondary fault zone, special techniques were used for design and construction of diaphragm walls in order to install continuous horizontal reinforcement, which is quite different from the traditional methods. Therefore, the application of the diaphragm wall with continuous horizontal reinforcement is used for the first time in Turkey.

The Morine to Merdare Kosovo Motorway allows the newly founded Kosovo, to become an important pillar at the center of Eastern Europe’s transport system, improving the economy and lives of Kosovo’s citizens; as the World Highway magazine mentioned in their article “Road to prosperity.” The Morine to Merdare Motorway spans from the Albanian border to the Serbian border, connecting Kosovo to the Trans-European Motorway and to the ports at Durres (in Albania). Connecting the newly founded country to the land and sea transportation grids in the region. It is the largest infrastructure project ever undertaken by the Government of Kosovo.

In April 2010, the Government of Kosovo authorized the construction of the 78 km Route 7 motorway from Morine to just north of the capital city, Pristina. The construction began within a month of signing the contract. The first 38 km part was completed in 18 months and project is fully completed in less than 44 months.

This east-west motorway serves as the centre-piece of Kosovo’s national transport system and promotes trade and development in Kosovo and throughout. It also improves road safety, and acts as an economic engine to increase investment in the country. The trade route created by the motorway will contribute to the economic integration of the countries from South-eastern Europe, Western Europe, and beyond.

UNIQUE CHALLENGES

The Sections 1,2,3 and part of the Section 4, making 38 km altogether are completed in 18 months including all design and expropriation, with the highest standards of construction. This period is the shortest period of construction for a 38 km motorway section built up-to-date.

The project has implemented a world-class safety program and has developed strong working relationships with all stakeholders and communities that are involved and impacted by the project.

The Project delivered the first 38 km in 18 months with prompt mobilization of equipment and personnel, applied the quality management system and safety procedure, completed segments of the motorway earlier than scheduled dates and within budget and achieved all these with support of the Client.

LOCATION:Rreshen - Kalimash, Albania

OWNER / CLIENT: General Roads Directorate of the Government of Albania - GRD

PROJECT DURATION:Oct 2006-Oct 2010

CONTRACT TYPE:Construction & Design Management



• The largest public contract ever signed in Albania

• Reduces transportation time from 8 hours to 2 hours

PROJECT DESCRIPTIONThis project is the largest public contract ever signed in Albania. Undertaken by ENKA and Bechtel in September 2006 the Rrëshen-Kalimash Motorway Project is a key connection between Durres Port, Albania’s primary harbour on the Adriatic Sea, and Kosovo.

The 61 km motorway crosses the mountainous northern region of Albania, linking the cities of Rrëshen and Kalimash, and is divided into three sections. Its designers are Scetauroute (France) for Sections 1 and 3, and Italconsult (Italy), for Section 2. Section 1 is an 18 km long stretch from Rrëshen to Reps, section 2 is 27 km long and travels from Reps to Thirra, section 3 connects Thirra and Kolshi and is 15 km long. At Mount Runes, at an altitude of 1,858 m, the construction includes a 5.5 km long double bore tunnel.

In addition to the many economic and social benefits, from the construction of this Motorway, the transportation duration between Tirana and Kosovo border is reduced from 8 hours to 2 hours.

UNIQUE CHALLENGES

The most challenging part of the whole corridor was the segment between Rrëshen and Kalimash, which is around 61 km long. Before the motorway, transportation was provided by poor old mountain road and travel time was eight hours. The Rrëshen - Kalimash Motorway’s main purpose is to serve as a faster and safer route through the mountainous region.

Difficult terrain conditions and harsh climate conditions were two big challenges. To cross this difficult terrain, bridges, viaducts and tunnels were designed and constructed. Due to the 800 m of overburden on top of the tunnel, it was not possible to reach anywhere across the tunnel alignment except the entrance and exit locations. In order to reach portals of the tunnel, 17 km of service road were constructed. This service road was closed for 3 months in the year due to the harsh weather conditions. The total service road constructed for this project is 92 km.

In addition to difficult terrain and harsh climate conditions, geological conditions were not stable and continuous throughout the tunnel and motorway alignment. This enforced engineers to use more than one method during construction.

Despite the difficult conditions, the project was completed successfully and the travel time is reduced from eight hours to two hours. In addition to the great amount of travel time saved, the motorway enabled a safe means of travel in the region. This new route will serve to stimulate the economy in Albania’s north-eastern region.


The Motorway is designed as dual carriageways of 2X3.75 m, supplemented with 2-meter emergency shoulder lanes. The major work items comprise of 34 million m3 of excavation, 13 million m3 of earth filling, 0.5 million m3 of concrete, 1.6 million tons of subbase and cement treated base and 0.45 million tons of asphalt. The construction of bridges and viaducts at an altitude of 5 km in the challenging mountainous terrain of Albania is included in the contractual works. At Mount Runes, at an altitude of 1,858 m, construction includes a 5.5 km long double bore tunnel.

PROJECT DURATION:Jul 1998-Jul 2004




• Links Croatia and its touristic destinations to Pan-European Transportation Corridor

• Honored with the 2004 Croatian Contractor Safety Award

PROJECT DESCRIPTION

This important motorway project’s total length amounts to 156 km and consists of two separate sections. Section 1, the 13 km Bregana-Jankomir motorway, is a four-lane link from the capital city Zagreb to the border of Croatia and Slovenia, and was opened to circulation in December 2000. The other section, the 143 km Bosiljevo-Sveti Rok motorway, linking central Croatia to the Dalmatian Coast, opened in July 2004.

The motorway is considered vitally important as it provides the principal link between the Zagreb region in central Croatia and the Dalmatian coast. With this motorway, Croatia’s Dalmatian coast is now integrated with Europe’s central and western highway network.

The project was an enormous success. ENKA and Bechtel, who had undertaken the turnkey construction of the motorway in April 1998, completed the project 14 months ahead of schedule, with 4,000 workers employed at the peak of the construction. The project is further distinguished for winning the 2004 Croatian Contractor Safety Award, as it was successfully realized without any compromise in quality or safety.

ENKA assisted client to facilitate US EXIM Bank and OPIC financing for the project.

UNIQUE CHALLENGES

Habitat fragmentation occurs when human-made barriers such as roads, railroads, canals, electric power lines, and pipelines penetrate and divide wildlife habitat. Of these, roads have the most widespread and detrimental impacts. To decrease this impact, in Bregana-Zagreb-Dubrovnik Motorway, 6 wildlife crossings were constructed.

ENKA also determined 70 places of sinkholes on the alignment and adopted its construction methodology to cross over them considering all environmental aspects.

The project was completed in 14 months ahead of schedule, with 4,000 workers employed at the peak of the construction. The project is further distinguished for winning the 2004 Croatian Contractor Safety Award, as it was successfully realized without any compromise in quality or safety.


Over the construction, 21 million m3 of earthwork were excavated, 0.65 million m3 of concrete were poured, 19 million m3 of fill material were used and 4.6 million tons of subbase and cement treated base, as well as 1.18 million tons of asphalt, were laid. The works also included the construction of bridges and viaducts reaching a length of 8 km.

PROJECT DESCRIPTION

The Gerede-Ankara and Ankara Peripheral motorway project is one of the largest infrastructure development projects in Turkey. The total length of the motorway is 230 km. It forms a significant part of the Trans-European motorway (TEM). As a major link to the Trans-European Motorway connecting Europe with Iran, the motorway is vital for transporting goods to and from Middle-Eastern markets. The six- to eight-lane high-speed toll way was built in two sections. The first section, a six-lane, 115-kilometre segment, connects the capital, Ankara, with the town of Gerede; the second is an eight-lane, 115 km beltway circling Ankara. It goes through terrain with very difficult and complex geological formations and has been designed in accordance with the highest world standards and specifications.

The project has been executed with a peak manpower of 6,296. This includes the resources and expertise of local contracting companies employed as subcontractors. Plant and equipment to the total value of US$ 130 Million has been used on the project. Resulting highway system is critical to Turkey’s future economic standing, providing the final link for freight and other road traffic between Istanbul, Turkey’s European port, and Ankara. The Ankara-Gerede Motorway demonstrates our ability to provide everything from crushed rock to sophisticated financing for successful completion to Client requirements.

ENKA assisted the client to facilitate US EXIM Bank financing for the project.

UNIQUE CHALLENGES

Building the motorway was a challenge. In some sections the road reached heights of 1.5 km above sea level and yet our team excavated more than 163 million m3 of earth and rock. At peak, excavation reached 6.5 million m3 on August 1990. There was 16.2 million m3 of embankment, and 4.7 million m3 of embankment was accomplished as a peak on August 1990. At the same time, 1.24 million m3 of concrete was poured for the project and 107 thousand of ton rebar were installed, which includes 63 overpasses and underpasses, 25 bridges and viaducts and 560 box culverts. Most of the bridges are of standard design consisting of concrete piers and precast/prestressed concrete U-beams. 5.1 million tons of asphalt was placed and over 332 thousand tons of asphalt was the record on August 1991. The quantity of crushed aggregate was exceeded on 31 million tons.

The alignment traversed rugged terrain, in some places reaching heights of 1.5 km above sea level. Our team mobilized almost 1,500 pieces of heavy construction equipment to accomplish work under difficult weather conditions, including rain that turned fresh excavations into lakes.

Our team of international professionals brought the following experience and capabilities to the Ankara–Gerede Motorway project:

• Complex, megaproject delivery• Maintaining schedule while traversing remote, rigorous terrain• Recruitment, training, and maintaining of a large local workforce and deployment of mobile camps• Coordination between multiple work sites • Timely handling of significant quantities of excavation, backfill, concrete and steel at multiproject locations• Movement of heavy equipment as necessary


The alignment forms a significant part of the Trans-European Motorway (TEM). This part of the Motorway system passes between Gerede and Ankara and around the city of Ankara. It goes through terrain with very difficult and complex geological formations and has been designed in accordance with the highest world standards and specifications. ENKA has executed this project with a peak manpower of 6,296. This includes the resources and expertise of local contracting companies employed as subcontractors.

Within the integrated JV, ENKA provided onsite management and supervision, engineering, cost and schedule control, procurement, quality assurance/control, testing and startup, and environmental mitigation. The scope also included licensing and permit applications, utility and drainage system relocation, technology transfer, and public outreach, including the management of almost $100 million in specialty subcontractors for the Government. With almost 6,000 Turkish workers, it was one of our largest international direct-hire jobs.

Construction works consist of 163 million m3 of excavation, 117 million m3 of fill, 1.2 million m3 of concrete, 24 thousand m of pile, 450,000 m of drainage pipe, 16.5 million tons of subbase & CTB and 5.1 million tons of asphalt.

As with all our projects, ENKA implemented its ‘Zero Accidents’ safety policy. Our Lost-Time Injury rate for the project was 0.98 for a total of 27,449,339 staff-hours worked.

PROJECT DESCRIPTION

As a prime contractor ENKA began the construction of the stadium in 2006 and completed in 2009. To meet a tight schedule (three years) for erection works of the five-star arena over 1,600 people worked on site at peak times.

Turn-key construction of UEFA Elite Class stadium in Donetsk, Ukraine for 52,667 visitors, of which 3,680 are VIPs. The Stadium is an oval shape with an inclined roof. Inside the Stadium there are restaurants, bars, cafes, fast food facilities, a sports center, Club Museum and Shops.

The eye-catching stadium was designed by Arup Sport, which was the creative and inspirational force behind some of the world’s greatest arenas, such as the City of Manchester Stadium (Manchester, England), Allianz Arena stadium (Munich, Germany), the new stadium of Valencia CF (Valencia, Spain), Sydney Football Stadium (Sydney, Australia), Beijing National Stadium (or the Bird’s Nest in Beijing, China) etc. The total project budget was US$ 400 million.

CAPACITY• The total seating capacity of the stadi-

um is 52,667.

• There are 290 seats for the media, of which 152 are for journalists and 138 seats for TV commentators (a combi-nation of 46 commentary boxes).

• A total of 196 places and seats for peo-ple with disabilities and their carers (104 and 92, respectively).

• The stadium’s 44 corporate boxes can accommodate a total of 915 people.

• Altogether 180 media representatives can always feel at home at the arena’s spacious Conference Room.

• All the restaurants, bars and cafés at the stadium combined, total 1,830 covers.

• The stadium has more than 1,000 car parking spaces (245 of which are un-derground).

UNIQUE CHALLENGES

Set within the beautiful Leninsky Komsomol Park, this stunning new home for FC SHAKHTAR has become a new symbol for Donetsk city, while providing an unforgettable match experience for spectators.

Its bowl design offers a high degree of comfort, as well as improved viewing quality. Immediately adjacent to the seating areas are a range of facilities catering for every fan’s needs. In addition to adhering to Ukraine’s codes and standards, the stadium’s design meets the most current internationally recognized safety standards. The roof includes a large area of translucent sheeting material to improve daylight and sunlight penetration and promote improved natural turf-growing conditions. Furthermore, large open areas are incorporated into the perimeter of the lower-tier concourse to enable cross ventilation of the pitch. The external elevation of the building provides a seamless glazed facade and a high degree of transparency to the exterior of the building.

The stadium combines an elegance of form with simplicity of materials. It has become a landmark stadium for world class players and a worldwide audience. The stadium’s conceptual design was developed to meet the specific requirements of the club for a natural playing surface, a seating capacity for 51,500 spectators, qualification for UEFA elite status, VIP suites with segregated viewing areas and underground VIP parking, as well as additional facilities such as a club museum, a club shop, a cafeteria and a health club. During the construction, considerable de-watering works were carried out to reduce the level of the underground water table. These were followed up with piling works to improve the load bearing capacity of the soil by using 400 mm x 400 mm friction piles. The tiers comprised a total of 3,400 pre-cast concrete elements. The total amount of concrete used in the works amounted to 120,000 m3. The roof is a three dimensional, structurally efficient design that appears to float above the building. The shape inclines towards the south, resting on a dozen 60 m long steel support trusses that were manufactured and erected by Çimtaş and maneuvered with a giant, 600-ton mobile crane, able to lift steel structures in excess of 230 tons. These 12 steel support trusses designed and manufactured by Mero-TSK have a combined weight of 4,000 tons and carry the space-frame structure of the roof.
