Third casting at the Espoonlahdentori entrance at the end of March

30.3.2019

Concrete casting at the Espoonlahdentori entrance of the Espoonlahti metro station will be carried out during the week of 25 March as part of the construction of walls for the west entrance.

The work is scheduled to begin on Thursday, 28 March, at 5.00 am and will be completed on Friday, 29 March, between 4.00 am and 7.00 am. The casting work is a long process, and unfortunately late-night work cannot be avoided; due to the height and size of the structure, the pouring of concrete must be completed in one go.

The driving of concrete trucks and pumping of concrete may cause noise. We apologise for any inconvenience.

Construction on the Iivisniemenkallio shaft is moving forward

27.3.2019

Construction at the Kaitaa metro station is proceeding, and construction work on the Iivisniemenkallio shaft will increase starting the week of March 18th. The Iivisniemenkallio entrance shaft is still provisional.

A large truck-mounted crane arrived at the entrance to the worksite on Thursday, 21 March. The shaft’s weather protection will be dismantled. Concrete-truck traffic near the site will increase due to the construction of the concrete structures, and a tower crane will be set up at the worksite. In addition, aggregates will be transported within the vicinity of the worksite, and prefabricated elements will be delivered to the site. Rock anchor drilling will take place inside the entrance shaft.

Work at the site will generally be carried out from Monday to Friday, between 7.00 am and 6.00 pm. Heavy traffic is routed from Kaitaantie to Hannuskalliontie, and from there to the worksite area.

We apologise for any inconvenience caused by the construction work.

Smoke-extraction and emergency-exit shafts for phase II of West Metro – element deliveries in spring

20.3.2019

The West Metro rail line project includes not only the construction of the rail tunnel, but also seven technical shafts designed for ventilation, smoke extraction and pressure equalisation in the completed metro. The shafts will also serve as emergency exits.

Prefabricated elements will be delivered to the shaft construction sites, and during the installation stage, prefabricated stairs, stair slabs, columns and wall elements will be installed in the shaft over a total height of eight floors.

Traffic near the shafts will increase when the elements are being delivered: concrete mixer trucks will deliver fresh concrete for the casting once or twice a week. Cranes will mainly be used outside the period of 7 am–3 pm on weekdays, and passenger cars and vans will otherwise be used for site traffic.

Once the installation work has been completed, construction will continue with work on the aboveground structures of the shaft. Work at the shaft will be carried out from Monday to Friday between 7 am and 6 pm.

Element deliveries have already begun for the shafts at Hyljetie, Soukanväylä, Opettajantie and Maininkitie, and they will begin at the Suomenlahdentie, Riilahdentie and Kauklahdenväylä shafts in April and May.

Estimated installation schedule for shaft elements in 2019:

January–July Hyljetie shaft
January–August Soukanväylä shaft
March–June Opettajantie shaft
March–July Maininkitie shaft
April–October Suomenlahdentie shaft
April–September Riilahdentie shaft
May–December Kauklahdenväylä shaft

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

19.3.2019

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

15.3.2019

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

15.3.2019

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.
