BIMsummit Estonia, Estonia’s largest conference focusing on BIM and digital construction, will take place for the fifth time on 11 March. For the first time, the focus is on digital construction in the field of infrastructure. The conference highlights developments in the field in Estonia and the wider world and shares the most salient topics and most illuminating experiences of practitioners.

Reaalprojekt OÜ has an important role in the development of Estonian InfraBIM. Celebrating its 20th anniversary, the company offers a full range of infrastructure design services and has helped implement more than 1000 projects over the years. Among them are several projects that rely on InfraBIM principles. Reaalprojekt OÜ chairs the InfraBIM working group of the Digital Construction Cluster.

In terms of engineering design, this is the largest project in Estonia in which BIM is used for modelling both roads and buildings. The outdoor parts of the quarter – roads and utility clearances and networks – were designed by Reaalprojekt. BIMsummit Infra 2021 At the web conference, the head of the company’s project department Taavi Sadam will share Reaalprojekt’s experiences with the implementation of BIM and the engineering work performed in Kvartal. 

BIM is used to produce an integrated model for conflict detection and information management throughout the building lifecycle. BIM design is becoming the new design standard, which will replace the usual drawing on paper with 3D information models.

InfraBIM is a process developed for the design, construction and management of infrastructure, where an information-rich 3D model is at the heart of the entire process. 3D modelling allows the creation of a visual model, the analysis of possible conflict points in the structure, the detection of design errors and the comparison of different options and their costs. It is also possible to generate 2D drawings and rapidly develop several technical versions of the project. 3D modelling also helps in administering the road maintenance information system.

The conference is free of charge for the public.

In February, construction began on the second stage of the pedestrian and cycle path connecting Filtri Road with the Kadriorg district and Ülemiste terminal in the centre of Tallinn: a two-part pedestrian and cycle bridge (with an observation platform) connecting the Majaka neighbourhood and Kadriorg will be completed. The engineering work on this project was performed by Reaalprojekt OÜ.

The bridge will allow a smooth transition from Majaka Street to the pedestrian and cycle paths originating in the Kadriorg district and leading toward Filtri, Gonsiori and Poska streets. In the bigger picture, the bridge will connect the Lasnamäe, Pirita and Kesklinn network of pedestrian and cycle paths. The pedestrian and cycle bridge starting from Majaka Street continues the trajectory of the Majaka Street cycle path and creates a link between the two districts. The pedestrian and cycle path project was prepared by Reaalprojekt OÜ and is being built by TREF Nord.

The two phases of engineering works carried out by Reaalprojekt included a total of 1.78 km of pedestrian and cycle roads, 0.13 km of bicycle paths, 0.014 km of sewerage pipes and monolithic reinforced concrete structures for two bridges (one of them a four-span slab superstructure and the other a prestressed slab superstructure). “Visually, these will be attractive, curved reinforced concrete structures on posts. The first bridge has a geometry that resembles the shape of a horseshoe and is variable in width. The second bridge has a total length of 50 metres and has a flatter S-shape,” said Aleksei Muzalevski, the head of the bridge group of Reaalprojekt OÜ.

In addition to the two-part pedestrian and cycle bridge, street lighting will be built, utility networks will be upgraded and landscaping work will be carried out. The public will delight in the construction of a viewing platform.

The deadline for completion is October 2021.

The developer Kapitel and construction company Merko signed a contract for underground construction works and the construction of external pipelines of one of Estonia’s largest projects, the Liivalaia business and residential quarter, which will be erected opposite Hotel Olümpia at the intersection of Liivalaia and Juhkentali streets. There will be three interconnected buildings in the quarter, including the tallest office building in Estonia. The outdoor parts of the quarter – roads and utility clearances and networks – were designed by Reaalprojekt.

With a gross area totalling 77,000 square metres and an area of 36,000 square metres to be leased out, the quarter consists of three buildings and a connecting parking garage. In addition to office space and rental apartments, the quarter will have 5000 square metres of various catering and service space, a 25-metre swimming pool for employees of companies working in the quarter, a sports club and mini-spa, beauty and health services as well as rooms for conferences, meetings and events. The quarter’s two-storey underground car park and above-ground parking garage will have a total of 470 parking spaces and a car wash, Estonia’s largest indoor bicycle parking and bike wash station and changing rooms and showers.

A square will be built in front of the buildings and two new access roads to Imanta and Võlvi streets will be built in addition to a green area and a public park along Veski Street, from which a pedestrian and cycle path runs along the channel of the former Härjapea River.

In terms of engineering design, this is the largest project in Estonia in which BIM is used for modelling both roads and buildings. BIM is used to produce an integrated model for conflict detection and information management throughout the building lifecycle. BIM design is becoming the new design standard, which will replace the usual drawing on paper with 3D information models.

The architect of the quarter is Martin Aunin and the interior architect is Arhitekt11. Kapitel’s total investment in the quarter is approximately 100 million euros. The cost of the contract for the underground works and the construction of the external pipelines is approximately 14 million euros and the works will last 19 months.

The construction of the first stage of the pedestrian/cycle path connecting Filtri Road with the Kadriorg district and Ülemiste terminal has begun in the centre of Tallinn. The engineering work on this project was performed by Reaalprojekt OÜ.

During the implementation of the project, a new route for pedestrians and cyclists will be built, which includes connecting Tehnika Street and Filtri Road to the Kadriorg district and Ülemiste terminal via the Odra Street, Türnpu Street, Vilmsi Street and Vesivärava Street pedestrian/cycle path. In the second stage of the project, a pedestrian/cycle bridge with an observation platform will be built to connect Gonsiori Street to Majaka Street.

The design of the pedestrian/cycle path connecting Filtri Road with the Kadriorg district and Ülemiste terminal was prepared by Reaalprojekt OÜ. The engineering work included a total of 1.78 km of pedestrian and cycle roads, 0.13 km of bicycle paths, 0.014 km of sewerage pipes and monolithic reinforced concrete structures for two bridges (one of them a four-span slab superstructure and the other a prestressed slab superstructure).

The construction works of the first stage will be performed by Tallinna Teed AS and the deadline for the works is November 2020. The construction of the pedestrian/cycle path was commissioned by the city of Tallinn’s environment and public utilities department.
