Kivenlahti station to become part of densifying city – station construction on schedule

The construction of the West Metro’s Kivenlahti station is progressing on schedule and within budget. The extent of the area being built corresponds with the construction of a medium-sized shopping centre. Altogether 10,000 cubic metres of concrete will be cast during the contract.

In addition to element installations and in-situ concrete casting, the station construction project currently involves the building of heating, water and cooling trunk lines, the installation of fire hydrants, the installation of ventilation ducting and fire dampers, cable trays and lighting systems and cable laying work. Also the installation of massive smoke extraction fans has begun.

The Kivenlahti station construction contract began in June 2018. The contract includes the Kivenlahti metro station, service tunnel and the Kivenlahdentie and Kivenlahdentori entrances.

“The goal is to be able to seal off the above-ground structures by the end of the year so that the work can be continued regardless of weather conditions. We work closely with the city of Espoo in the construction of the area. The city is growing and developing around the metro,” says the Kivenlahti station’s Real Estate Development Manager Janne Nordström from the West Metro project.

Skanska is the main contractor for the Kivenlahti station. The contract currently employs around 140 employees who represent 12 different nationalities: in addition to Finns, the employees come from Estonia, Spain, Russia, Latvia, Lithuania and Kosovo, for example. Around half of the employees are Finns.

“Logistically, metro stations are demanding as the majority of the construction work takes place underground. Data models and prefabricated parts, in addition to in-situ casting, are used in the construction. This speeds up the construction schedule,” explains Petri Mälkiä, Project Manager at Skanska Infra Oy.

Along with the metro, other construction projects will start up in the area. The Kivenlahti Metro Centre will be located at the Kivenlahdentie entrance, i.e. the westernmost entrance, and will provide new services for the area. When metro traffic starts up, the Kivenlahdentie entrance will not yet be open to passengers due to other construction ongoing in the area. The entrance will be opened when the Kivenlahti Metro Centre and its services are inaugurated. A similar set-up has also been in place at the phase one Tapiola and Matinkylä stations. In Tapiola, the southern entrance was taken into use in spring 2019, and in Matinkylä, Länsimetro Oy is currently building the western entrance, which will be opened in 2020 when the Tynnyripuisto hotel and other construction is completed.

The “Kulkijat” (Wanderers) sculpture by the artist Kalle Mustonen will be placed in the Kivenlahti station, where it will serve as an iconic landmark. The sculpture consists of two wooden figures which are two and three metres tall. The piece serves as a contrast to the whiteness of the Kivenlahti station and Kivenlahti area. A naming competition will be organised for the figures at a later date.

Approximately 8,000 people currently live in Kivenlahti. The number of residents is expected to grow so that the population of Kivenlahti will be approximately 25,000 by 2050. The Kivenlahti metro station will be completed in 2022.

In the Matinkylä–Kivenlahti section of the West Metro project, seven kilometres of rail line and five new stations will be built, in addition to an underground metro depot in Sammalvuori.

Phase II of Länsimetro proceeding on schedule and on budget

Construction of phase II of the West Metro project, from Matinkylä to Kivenlahti, is proceeding according to plan. In March 2018, the City of Espoo reviewed the project plan for phase II that it had drawn up in 2012. The adjusted cost estimate for the project is EUR 1,159 million. The aim is to hand over the seven-kilometre section of rail line and the five stations and depot to the operator, Helsinki City Transport (HKL), in 2023.

Six construction contracts are currently under way: five station contracts and the construction contract for the entire rail line. Technical building services have already started at the Sammalvuori depot, and the depot will be completed in 2020. In the construction contracts, the work is now moving from concrete work and the installation of prefabricated elements to work on technical building services and system installations.

The construction contracts are being implemented as so-called project management contracts, the scope of which is similar to the construction of a mid-sized shopping centre. In addition, the project includes 26 subcontracts, with estimated sizes ranging from one million to more than 10 million euros.

The integrated project organisation that is building the West Metro moved to shared premises in Olari, Espoo, in spring 2017. The project’s key players and the reinforced organisation operate under one roof: authorities, planning, construction, finance, quality and risk management, as well as representatives from metro operator HKL, rescue services and the City of Espoo.

In compiling the project organisation for phase II, the experiences gained from the construction of phase I have been taken into account with great precision under the lead of CEO Ville Saksi.

“Even by European standards, the West Metro is a major project, combining infrastructure construction, building construction, technical buildings services expertise and automation. Our goal is to build a metro system that is in line with the project plan and which is assuredly one of the safest in the world. It is of the utmost importance to us to openly communicate on our progress,” states Länsimetro Oy’s CEO, Ville Saksi.

The phase II section of the metro will include five new stations: Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti. An underground metro depot for the needs of metro traffic operator HKL is being built at Sammalvuori.

Construction is full-steam ahead at Soukka – 80 per cent of the station’s concrete has been cast

The construction contract for the Soukka station began in August 2018. Eighty per cent of the station’s concrete casting and element installations have now been completed. The contract involves casting close to 10,000 m3 of concrete and installing approximately 1,800 elements. Work on the station’s technical building services was started in June and included the installation of ventilation ducts, water and sewage pipes and sprinkler pipes.

The contract covers the construction of the Soukka metro station, its technical shafts, two entrances and a service tunnel from Soukanväylä to the station. The Soukantori entrance will have two storeys. Four side-by-side elevators will ensure smooth movement directly to the platform level. A second entrance will be situated on Yläkartanontie, with entry to the metro via escalators and an inclined elevator. The station will feature an art installation called “Sfäärit” (Spheres) by Taneli Rautiainen. The four elements of the art installation will be located vertically in different parts of the metro station, from the platform via the elevator shaft and to the Soukantori entrance.

Länsimetro’s modern metro system is made up of 52 different systems. The automation systems include, among other things, HVAC automation, building supervision, power supply monitoring, camera and PA systems and access control. HVAC systems include pumping stations, smoke extraction fans, station-specific ventilation and overpressure fans and a fire water protection system. Other metro systems are, for instance, safety systems, fire doors and commuter information systems.

This year, at all stations the work will switch from concrete casting to the installation of technical building services, with the installation of various other systems starting at the same time.

“Construction at the Soukka metro station is proceeding according to plan. In addition to concrete work, the installation of cable trays, heating and cooling pipes, water and sewage pipes, a fire-extinguishing system and ventilation ducts is currently taking place. One goal is to have the roof structures ready at both entrances this year,” says Janne Tuoma, Construction Manager for the Soukka station in the West Metro project.

The consortium of YIT and ARE serves as the project management contractor for the Soukka station.

“The number of employees is currently at around 140. The challenge is the fragmented worksite area. The work takes place in several different areas. The plan is to provide heating during construction by means of district heating in autumn 2019. District heating will provide cost-effective and environment-friendly heat while the construction work is being carried out,” states Tomi Bergius, head of HVAC and electricity for the YIT/ARE consortium.

In the Matinkylä–Kivenlahti section of the West Metro project, seven kilometres of rail line, five new stations, and an underground metro depot in Sammalvuori are being constructed. The number of subcontracts is 26, and the project is being headed by an integrated project organisation with experts from 20 different companies. When the project ends, the stations and the rail line, including the technical systems for these, will remain under the ownership of Länsimetro Oy.

The Soukka metro station will be completed in 2022. The full project is expected to be completed in 2023, when, after testing and regulatory inspections, the Matinkylä–Kivenlahti section will be handed over to the metro operator HKL. The project is progressing on schedule and within budget.

In 2017, a 14-kilometre rail line from Ruoholahti to Matinkylä and eight new stations were completed. The stations and rail line on this section, including the technical systems, are owned by Länsimetro Oy. The section was handed over to the operator in October 2017. www.lansimetro.fi @metrorakentuu

 

 

 

 

Safety plans were appropriate in blasting operations that led to accident at Kivenlahti

On 29 July at 9 am, rocks flew into nearby properties during the construction of water and sewage connections near the Kivenlahdentori metro station entrance. The rocks broke 13 windows in nearby properties. No one was injured in the incident. Fire water and household water pipelines and rainwater and wastewater sewer pipelines and their wells are being constructed for the city of Espoo, near the metro entrance. In addition, a new district heating pipeline is under construction. Despite the safety precautions taken during the open excavation, some rocks hurtled into the nearby properties.

-The safety plan for the excavation work was drawn up appropriately. The individual performing the blasting operation had been familiarised with the work site and had the legal qualifications required to perform the work, and this was verified prior to the work being started. An investigation by authorities to determine the cause of the accident has been initiated but is not yet complete. Skanska is assisting the authorities in determining what caused the accident. The damage to the nearby properties will, of course, be repaired,” says Regional Director Pekka Räsänen of Skanska Infra, the contractor at the work site. “This type of accident is very rare in blasting work,he adds.

The company that carried out the blasting operation was a subcontractor of Skanska.

Excavation work is subject to strict liability. The excavation contractor is always liable for their own work. Excavation work is carried out in compliance with the Council of State Ordinance concerning safety during blasting and excavation operations and the Government Decree on the Safety of Construction Work. Every blasting operation is planned in advance. Excavation work is always performed by an individual who holds the qualification of blaster. A security guard is present during blasting to prevent anyone from entering the area and the vicinity. Warning sirens are also used in excavation operations. In open excavation, blasting mats are used to prevent rocks from flying into the surrounding environment. The force of each blast is recorded in a vibration meter.

-The West Metro will be the world’s safest metro. The safety of the employees working on the project and the area surrounding the work site is also a priority for us. We demand strict compliance with laws and guidelines from everyone working on Länsimetro’s work sites. We are one of the largest developers in Finland, and we aim to promote a strong culture of occupational health and safety in the construction industry, stresses Länsimetro Oy’s CEO, Ville Saksi.

Blasting on the work site was completed last week. Concrete and reinforcement work as well as technical building services work is currently under way at the Kivenlahti metro station. The construction work is moving forward normally. Excavation work on the West Metro’s stations and tunnels ended in 2018.

Glass wall at Matinkylä’s bus terminal completed

Construction of a glass wall at Matinkylä metro station’s bus terminal level has been completed. The glass wall was built from March to May at the bus terminal, in the area between the K-Market and R-kioski, to enhance the enjoyment of the shopping centre’s patrons and business owners.

“The end result looks as it should, it suits the space well,” says Perttu Tavia, who supervised the work on behalf of Länsimetro.

The glass wall was designed by the architecture firm HKP Oy, which also designed the Urheilupuisto, Niittykumpu and Matinkylä metro stations, as well as the Matinkylän bus terminal.

The wall was built at a busy junction where the metro entrance and the passage to the bus terminal and the shops at the bus-terminal level meet.

“Co-operation between the shopping centre, the business owners and the customers was good. If any development proposals related to the construction arrangements came up, the contractor took them into consideration right away,” says Tavia.

The glass wall keeps the heat in, especially during winter, making the bus terminal level a more enjoyable place to be. The wall’s three sliding doors operate with motion sensors. People can walk both in and out through all of the sliding doors. Two regular swing doors were also built into the glass wall.

The work was carried out by Hermanns Oy, Are Oy and Rakennuspalvelu Heino.

ABB to deliver facility monitoring system for phase II of West Metro

The facility monitoring system for the Matinkylä–Kivenlahti section of West Metro will be delivered by ABB. Once the project is completed, the system will ensure the availability, reliability and safety of all of Länsimetro’s 13 metro stations. The value of the delivery is EUR 10.8 million.

ABB’s delivery includes facility monitoring systems for all five metro stations of phase II: Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti. ABB will additionally deliver a similar system for the underground metro depot to be built in phase II.

The system will enable the real-time monitoring of the metro stations, metro line and maintenance tunnels, emergency exit shafts, station doors, elevators, escalators, lighting, smoke extraction and alarms, from the metro operator’s control room as well as remotely. In exceptional situations, the system will initiate automatic alarms and response measures. The control system to be implemented as part of phase II of the metro project will be connected to the system covering the entire Helsinki metro network.

“ABB implemented the control system for phase I of the metro project. We are pleased that the same contractor is also involved in executing this second phase, in which ABB is one of our most important strategic suppliers,” says Länsimetro’s CEO, Ville Saksi.

West Metro’s second phase is estimated to reach completion in 2023. Construction on the rail line and stations will continue until 2022, at which point the project will proceed to the commissioning phase. It includes the acceptance of contracts, a comprehensive testing phase and approvals by public authorities. Länsimetro Oy will have completed its task when the metro is handed over to the operator so that preparations for transit operations can begin.

 

Siemens to supply West Metro’s second phase with fire alarm systems

The fire alarm systems for West Metro’s Matinkylä-Kivenlahti section will be supplied by Siemens. The project will begin immediately with implementation planning. The first deliveries to the worksite will take place in a year’s time. The value of the agreement is EUR 4.4 million.

Siemens’ delivery will include fire alarm systems, linear heat detector systems for the rail tunnels and user interfaces for these at the stations.

“West Metro is one of the world’s safest metro systems. The majority of West Metro’s 52 systems are specifically related to safety during exceptional situations such as fires. Siemens’ solution meets the strict technical requirements set for the system. Siemens is also an experienced and competent supplier,” says Raimo Kaunismäki, Technical Director at Länsimetro Oy.

The systems to be supplied will be connected to the previously supplied control rooms for the fire alarm systems, after which the entire metro’s fire alarm systems will form a coherent whole. The systems cover all of the five new stations being built.

“The agreement is an indication of trust in a job well done and an excellent continuation of West Metro’s first phase,” says Jari Salminen, Senior Key Account Manager at Siemens.

West Metro’s second phase is estimated to reach completion in 2023. The excavation phase ended in 2018 and came in at EUR 14 million under budget. The rail line and five stations have moved on from excavation to the construction phase, which is proceeding according to schedule. HVAC and electricity work is already ongoing at the Sammalvuori depot.

Up until 2022, construction will continue at the stations and on the rail line after which we will move on to the commissioning phase, which includes the acceptance of contracts, a comprehensive testing phase and approvals by public authorities. Länsimetro Oy will have completed its task when the metro is handed over to the operator so that preparations for transit operations can begin.

Länsimetro selects Congrid Oy to manage quality and safety

Länsimetro has selected software company Congrid Oy, specialised in construction site quality and safety management and monitoring, as its partner for West Metro’s Matinkylä–Kivenlahti section.

Together, they have created a solution for the construction project through which Länsimetro can monitor in real time the safety situation, progress of quality inspections and the overall situation at each worksite. The solution offers a simple software tool for combining all of the worksite’s operations into a single package.

“In West Metro’s second phase we are building five stations, 14 kilometres of rail line and an underground depot. One station corresponds with the construction of a medium-sized shopping mall, albeit underground. We need the tools for managing and monitoring the big picture. Congrid is excellent for use at worksites,” says Länsimetro Oy’s Construction Director Tero Palmu.

This collaboration allows Länsimetro to monitor the quality and safety indicators of the construction project’s various phases in real time.

“We want to help this significant project and the people involved to reach their targets. We are grateful for this opportunity and the trust placed in us by Länsimetro,” says Congrid’s Sales Manager Oskar Smeds.

Data on a project of this size cannot be splintered into parts.

“We believe that Congrid offers unique possibilities for data-driven project management, and that by harnessing our software for hundreds of professionals to use, the results can be expected to be nothing short of excellent,” Smeds continues.

Länsimetro Oy’s Report of the Board of Directors 2018 – construction targets achieved

Länsimetro Oy is jointly owned by the City of Espoo and the City of Helsinki. The City of Espoo owns 84.4% and the City of Helsinki owns 15.6% of the company. The company’s task is to build, own, maintain and develop the West Metro.

The West Metro project is divided into two construction phases: Phase 1 Ruoholahti–Matinkylä, and Phase 2 Matinkylä–Kivenlahti. The owner cities have agreed that each co-owner is responsible for financing the investments in their own area, as well as for any maintenance costs arising from them. Costs that cannot be allocated according to that principle are generally shared in proportion to the geographically allocated costs.

The rail line and stations of the first phase were handed over to HKL on 3 October 2017. Länsimetro Oy owns the now-operating metro system, meaning the stations, rail line and related technical systems, and is responsible for its asset management, and for maintaining and developing its value.

HKL is responsible for the service and maintenance of the stations and rail line owned by Länsimetro, and also reports on these activities to the owner (Länsimetro Oy). HKL is also responsible for the metro traffic, operating two metro lines in the West Metro area, from Vuosaari to Matinkylä and from Mellunmäki to Tapiola. HKL furthermore owns the rolling stock, i.e. the metro trains.

Ruoholahti–Matinkylä

Länsimetro Oy handed over the stations and rail line to HKL on 3 October 2017, and by HSL’s decision, passenger traffic to Matinkylä began on 18 November 2017. Eight stations and the rail line, including the technical systems for these, remain under the ownership of Länsimetro Oy. HKL reports to Länsimetro Oy on the management and maintenance costs, and is accountable to Länsimetro Oy for the use of the rail line and stations and for related service and maintenance tasks. The operations are based on a co-operation agreement between Länsimetro and HKL that is steered by an agreement, co-operation, technical and finance group.

In 2018, HKL and Länsimetro jointly developed maintenance processes and reinforced the maintenance and asset management organisation. At Länsimetro, a maintenance organisation that employs two maintenance managers is responsible for operations. Life-cycle modelling was devised in 2018 for the maintenance function in order to optimise maintenance costs, and the drawing up of an operational strategy was initiated.

Work on phase 1 of West Metro continued in 2018 in Tapiola and Matinkylä, where accessibility to both metro stations was improved by building a second entrance to the station. For both Tapiola and Matinkylä, the new entrance is closely linked to the developing urban environment. In Tapiola, the entrance links to the shopping centre expansion and the new bus terminal, and in Matinkylä, the entrance will be connected to a new hotel project, and later to also to a swimming hall.

The stations currently in use were also improved. During the reporting year, five new kiosks were opened in the stations and vending machines were installed. Several development projects are also under way to improve, among other things, access control at the stations, technical surveillance systems and data transfer systems on premises.

Matinkylä–Kivenlahti

In the course of 2018, work advanced from excavation to construction on West Metro’s Matinkylä–Kivenlahti section. Construction contracts were tendered out in several stages over the year, and construction began on schedule at the five stations and on the rail line. The construction of the Sammalvuori depot has progressed to work on HVAC and electricity. In addition to the schedule targets, the cost targets were also achieved. The excavation contracts came in at approximately EUR 14 million below budget.

Other goals were also achieved. During the year, a total of 13,400 construction and production plans were completed. The key building permits needed to begin the construction work were obtained from the construction supervision authorities. Phase 2 includes a total of 24 subcontracts, 17 of which were tendered out during the year. The tendering process for the contracts that will be carried out later will continue until the summer of 2019. Occupational safety remained at a good level.

In March 2018, the City of Espoo approved an adjusted project plan for the Matinkylä–Kivenlahti section. The adjusted cost estimate for the project is EUR 1,159 million, not including financing costs and adjustments for inflation. The aim is to hand over the seven kilometres of rail line and the five stations and depot to the operator, Helsinki City Transport (HKL), during 2023.

The project as a whole is progressing within the cost estimate. All the construction contracts procured remained within budget. The subcontracts procured also remained within budget as a whole, although some exceeded their budget and others came in below budget. The cost forecast for planning has been updated.

The procurement of construction contracts was completed according to the procurement plan, and the procurement of subcontracts is also proceeding according to plan.

The construction work is mainly progressing according to schedule. At several sites, the work of contractors has begun slower than scheduled, due to insufficient resources or preparatory tasks, for example. These delays are expected to have no impact on the overall schedules of the sites.

Company finances in 2018

Länsimetro Oy’s permanent business activities are financed with charges collected from its owners, and construction activities are financed with external financing secured by its owners. The financial stability of the company’s operations depends on the reliable planning of operations financed with charges, and on forward-looking financing of construction operations.

Länsimetro Oy became the asset owner of West Metro’s first phase and covers its project-related maintenance and debt-servicing costs using charges collected from its owners. The stations and rail lines have been handed over to HKL, which operates the metro and maintains the metro system. HKL receives compensation from HSL for operating the metro traffic.

Administrative charges collected from the owners are used to cover the company’s permanent operations. In 2018, Länsimetro Oy collected EUR 2.8 million in administrative charges and 18.8 million in maintenance charges.

The company’s overall result was negative. This is due to two reasons: firstly, in 2017 more charges were collected than costs were charged. This lowered the income from charges for 2018, because part of the 2018 operations were financed with funds saved from 2017.

Secondly, the company’s loan repayments have not begun in full yet. For that reason, the loan repayments financed with charges are, for the time being, less than the planned depreciation, and as a result, the total depreciation and financial items are at a deficit. This will be corrected once the loan repayments begin in the coming years, and the current losses will be covered.

State subsidies related to the first phase of the metro have been paid in full. For phase 2, the State has committed to cover construction costs linked to the cost index of civil engineering works to a maximum of EUR 240 million, or a 30% contribution. State contributions in 2017 related to phase 2 were paid in spring 2018; the sum paid was EUR 35.8 million. The State contribution for 2018 will be paid in 2019, and the amount of the subsidy is approximately EUR 35.4 million.

The company finances investments primarily with loans that are guaranteed by the cities. A total of EUR 1,035 million in loans for phase 1 (Ruoholahti–Matinkylä) were withdrawn by the end of 2018. The first loan repayments began in stages in 2016.

By the end of 2018, EUR 305 million in loans was withdrawn from financial institutions for phase 2 (Matinkylä–Kivenlahti).

The purpose of Länsimetro Oy is not to produce a profit for shareholders. The company does not distribute dividends or assets in any other form than what is referred to in Chapter 13, Section 1, Subsection 1 of the Limited Liability Companies Act.

Siemens Mobility to provide traction power supply for second phase of West Metro

Siemens Mobility will provide the traction power supply substations for the Matinkylä–Kivenlahti section of West Metro. The contract is valued at close to EUR 5 million.

A consortium consisting of Siemens Mobility Oy and Electric Power Finland Oy will deliver the substations for traction power supply for the five metro stations and the Sammalvuori depot included in West Metro’s second phase. The substations will supply the electric traction power to the conductor rail of the rail line.

“The delivery of the traction power supply substations is one of the 24 subcontracts that extend throughout the metro line. Each subcontract is important for the overall success of the project. We are very happy to have an experienced implementer also for this contract,” says Raimo Kaunismäki, Technical Director at Länsimetro Oy.

The first deliveries will start in May 2019. The contract is due to be completed by summer 2021.

“The contract represents a successful continuation of West Metro’s first phase, for which Siemens also delivered the DC traction power supply substations. Siemens has a solid background and experience in traction power supply for rail traffic infrastructure,” says Jari Jokitöyrä, Sales Manager at Siemens Mobility Oy.

West Metro’s second phase is estimated to reach completion in 2023. The excavation work was finished last year. The rail line and five stations have moved on to the construction phase, which is proceeding according to schedule. HVAC and electricity work is already ongoing at the Sammalvuori depot.

Up until 2022, construction will continue at the stations and on the rail line after which we will move on to the commissioning phase, which includes the acceptance of contracts, a comprehensive testing phase and approvals by public authorities. Länsimetro Oy will have completed its task when the metro is handed over to the operator so that preparations for transit operations can begin.
