Lighting the Baltic Sea Region, Cities accelerate the deployment of sustainable and smart urban lighting

Welcome to LUCIA project blog!

Urban development is a skill. It is a democratically driven vision and professional design. It is a combination of land use solutions, architecture, geo-technics and investment. It is about recognizing and responding to the needs of the citizen. It is a prerequisite for urban life.

This page monitors the construction of a pedestrian route in accordance with the urban plan on the Porvoo Länsiranta area. In particular, monitoring focuses on the design and implementation of lighting solutions along the route. This is because the investment in lighting is backed by the LUCIA project, which focuses on smart urban lighting. Have a look at the entire project here.

A smart developer listens to users – participate and make an impact

The lighting of the new pedestrian and bicycle path in Länsiranta, Porvoo, is designed with the residents’ opinions in mind. The company in charge of the design, Ramboll Finland Oy, collected Porvoo residents’ opinions at the Porvoo Lights event in February. Now, the work will continue in a vision workshop.

The vision workshop is a part of an evaluation project, the purpose of which is to help residents have their voices heard regarding the lighting design of the pedestrian and bicycle path in Länsiranta. At the workshop, we will evoke wishes and needs from Porvoo residents with practical examples. The shared vision will be built on these.

Modern lighting technology allows for various types of implementation. If the needs and views of users are not considered during the design process, the lighting may be disturbing or otherwise unsuitable for its environment and purpose.

The vision workshop will be held remotely 16 April 17:30 – 19.00. You can sign up by writing an email yolanda.potrykus@porvoo.fi. A participation link will be sent to registrants. More information about the program will be announced later. Porvoo’s LUCIA work group welcomes all interested Porvoo residents to join in to work on our visions!

The last marks of the industrial history of Länsiranta

Soil contamination is analysed by studying the history of the land use and taking samples of the soil. In soil surveys, the ground is dug open with an excavator, or deeper holes are drilled into it, through which a specialised environmental expert takes samples. Some of the samples will be analysed with field measuring instruments, and some will be sent to a laboratory for environment-technical analysis. The samples will be analysed for heavy metals, hydrocarbon oils and polyaromatic hydrocarbons.

Based on the results of the analysis, a restoration goal suitable for the land use will be set so that health hazards and environmental hazards can be removed. The restoration plans of the Porvoo region are approved and supervised by the Uusimaa Centre for Economic Development, Transport and the Environment.

In the 20th century, Länsiranta was an industrial site. The planning area for the LUCIA project has been home to a box factory, storage buildings and a storage field for timber. The area was split by railway tracks used to transport raw materials for industry. Older Porvoo residents may remember the area’s change from the fields of the Näsi Manor into an industrial zone. Even bridges were built.

Back in the day, waste treatment and chemical storage were handled carelessly and short-sightedly. In Porvoo, the area is often referred to as the ‘Hankkija area’ and the ‘former mini-golf area’. The City of Porvoo has been restoring Länsiranta for over 15 years. Now only the most difficult-to-dig area by the riverbank remains.

Porvoo’s residents and tourists appreciate that the local history is visible in the environment. Good things, such as material efficiency, should be brought from history to modern times – in a contemporary manner through the development of recycled materials. The Finnish government has also developed legislation to re-use materials such as construction waste in a risk-free fashion.

Porvoo has prepared a roadmap for circular economy where the most significant goal is increasing the re-utilisation of extra soil. The planning will yield notable savings both in terms of money and carbon emissions.

A secret below the surface

The goal is to make Länsiranta a pleasant and durable coastal area for residents, passers-by and entrepreneurs equally. The LUCIA project has a significant role in the planning and implementation of the area. The lighting and the technology implemented in the LUCIA project will be seen by everyone moving about the area in little over a year. However, the preparations that need to be done in the area will be invisible to many.

Länsiranta consists of old seabed and river delta. The soil is deep and soggy clay both in the river delta and the entire Länsiranta area to be built. The soil is best described as ‘yoghurt’. At its best, or worst, the ‘yoghurt’ soil extends to the depth of 25 metres. Just imagine building something on that!

In the past, Länsiranta was an industrial zone. Because of this, the soil in Länsiranta is not only yoghurt but spoiled yoghurt. To build a pleasant and durable green area on this partially contaminated soil, the subsoil needs to be restored and hardened to carry the weight. The contaminated soil on the surface can be dug out and moved away, but the soggy clay will remain in place. It needs to be hardened and stabilised with pillars.

Soggy clay soil does not only involve sinking and contamination; we also need to ensure local stability so that the entire building mass of Länsiranta will not fall into the river once the clay bank gains weight from the new constructions. This has been partially solved earlier by stabilising a wall into the clay near the bank. It provides lateral support to the entire bank. This existing wall can be partially used in the LUCIA project, as well. However, there are spaces between the wall and the existing city quarter for which we need to plan and implement further stabilisation.

In practice, stabilisation means whisking hardening materials into the soil in pillar-shaped portions. Geotechnicians will define the binding agent recipes, dimensions of the pillars and plans for the stabilisation contractor. The city will order plans from the geotechnicians, hold a bidding competition for stabilisation contractors, supervise the work and then wait for the pillars to harden before anything else can be built in the area. This means that the stabilisation work will take more than six months.

The time and money contributed to the stabilisation process will not be visible to the general public. In the future, not many people walking on the LUCIA path will think about the secret below the surface in Länsiranta.

From design to implementation – Smart city lighting to Porvoo

Urban development is a skill. It is a democratically driven vision and professional design. It is a combination of land use solutions, architecture, geo-technics and investment. It is about recognizing and responding to the needs of the citizen. It is a prerequisite for urban life.

Well-prepared urban plans need to be initiated in order to be implemented. The journey from the design desk to making it tangible is a multi-step process – and often, in the opinion of the citizen, extremely slow.

This page monitors the construction of a pedestrian route in accordance with the urban plan on the Porvoo Länsiranta area. In particular, monitoring focuses on the design and implementation of lighting solutions along the route. This is because the investment in lighting is backed by the LUCIA project, which focuses on smart urban lighting. Have a look at the entire project here.

But before the lights come on, there are many interdependent steps along the way. The pedestrian route will be built in challenging conditions for civil engineering. In the end, installing the lighting is just one step among others.

This page explains the numerous preparations required for successful implementation. Welcome to see how the route is built and what the journey from the design table to the finished result is.
