Construction of the west metro began in November 2009 at Ruoholahti. Initial inspections will be carried out on all buildings in the immediate vicinity of the future metro line prior to the start of excavation.
The aim of the inspections is to examine the structure and condition of the buildings and to document property. Along with the examination procedures, any fragile equipment in flats and offices will be protected. Normal items of sensitive equipment found in households are desktop computers with hard drives, conversely, portable (notebook) computers, video projectors or digital set-top boxes with recording capability do not require separate protection. Not all sensitive equipment can necessarily be protected in connection with the initial survey. In this case, a new visit is agreed at the site, or the resident/office staff receives protective ‘paws' which are easy to place underneath the equipment.
Once the construction project is complete and any resulting damage is recorded, a final survey is performed. Länsimetro is responsible for the compensation of any and all damage to property caused by their excavation work.
Inspections in the Ruoholahti area apply to all property located within approximately 100-150 metres of the metro tunnel to be excavated. The Ruoholahti project covers excavation work of the tunnel from Ruoholahti metro station to the waterfront at Salmisaari.
The inspections will be carried out by Länsimetro's expert partner, Kalliotekniikka Consulting Engineers Ltd. The company will contact the owner or house manager of each building in order to make arrangements for the exact time of inspection. Before the survey begins Kalliotekniikka Consulting will provide information in greater detail in a separate letter concerning the date of the survey and types of procedures to be used.
