Additionally, Lombard provided on-site assistance during construction | Chile | | Muttsee Photovoltaic Plant | References_8674 | The Muttsee dam of Kraftwerke Linth-Limmern AG is located at 2’475 meters above sea level and faces south. Due to the good, elevated location and the orientation of the dam, Axpo developed a project for the construction of a photovoltaic plant on the outer dam wall. Due to the high snow volumes, the solar modules are not installed on the lowest section of the dam.
This results in a solar power plant with a capacity of about 2 MW, distributed over an effective solar module area of about 10’000 m2. The estimated average installed capacity is of about 2.8 GWh/a. An additional technical control room will be built north of the guard house of the pumped storage plant Limmern for the power evacuation.
Lombardi Ltd. was commissioned by AXPO for the design of the technical control room of the photovoltaic plant. The commissioned work includes the SIA phases 32, 41, 51 to 53 for civil works and HVAC equipment.
| Switzerland | | Migros - Avry Center - Ventilation of the Access Tunnels | References_6229 | The current site occupied by the Avry Center aims to become a new destination, a place of exchange, culture, leisure and encounter. It is also the project of a new vibrant public square, connected to Avry, to Matran, its region and its landscape composed of agricultural fields, the river Saane and the Fribourg Pre-Alps in the background.
This new public square will live at the pace of three major stakeholders: a new shopping mall incorporating various programmes and public services (including a wide range of catering facilities, a medical centre, a Migros Club School and a fitness centre), a swimming centre open to the public and schools, as well as a multiplex cinema with a varied programme.
A new neighbourhood of attractive and innovative housing will also be developed in the freed space of the former Mall. This mixed neighbourhood will ensure a quality of life due to its opening onto the great landscape and its connection to the surrounding nature.
Lombardi takes charge of the design, sizing and realization of the ventilation and smoke extraction system of the 3 underground accesses to the new Mall:
- The logistics access will be equipped with a vertical ventilation station
allowing the extraction of smoke in case of fire
- The client accesses North and South will be equipped with jet fans for
removing smoke from the access structures longitudinally. | Switzerland | | Fréjus Tunnel - General contractor for the construction of the technical room ST2-01-20 | References_7392 | Coming soon... | France | | IM Maggia - Energy related renovation of the administrative building | References_7091 | Feasibility study, cost estimation, tender design and detailed design for summer/winter air-conditioning systems, sanitary installations for a multi-storey building used for offices, meeting rooms and cafeteria.

The building from the 70s needed a complete renovation. Lombardi Ltd. was charged with the design services (Ph. 32 due diligence + Ph. 41 tender phase + Ph. 51 execution phase) of the new heating and cooling system, the air conditioning, the sanitary and sewage system (waste water and rain water) and the renewal of the fire extinguishing system (sprinkler system).
Great attention was given to user needs in terms of functionality, comfort (thermo-hygrometric conditions, acoustic effects of the installations) as well as energy consumption and environmental sustainability.
The energy for heating, air conditioning and domestic hot water is generated by heat pumps supplied with industrial water. The production of domestic hot water also uses the waste heat from the cooling of the refrigerators of the cooling chambers. The hot water for the fitness center is produced by a gas boiler.
A mixed system (ventilation + fan coil) ensures compliance with the required conditions and allows for a high level of system flexibility. Air treatment units with heat recovery ensure high indoor air quality and reduce energy consumption.
The rehabilitation of building and technology while maintaining the shopping center in operation was a major challenge and was resolved through disciplined planning, organization and management (installation of the new system in parallel with the operation and dismantling of the existing system).
The works were successfully completed, and the safety of the users was ensured at all times by carefully defining timing and logistics and coordinating the collaboration of the various professionals. | Switzerland | | ATG - Gotthard Base Tunnel - Portal Area Sedrun | References_597 | In the portal area of the access tunnel Sedrun there are several structures that are required for the operation of the 57 km long Gotthard-Base Tunnel. The main elements include:
Railway Infrastructure Building, Sedrun:
Two-storied building in solid construction, in which the facilities for the railway infrastructure are installed. Two facades of the approximately 40 m long, 15.5 m wide and 10 m high building are made of exposed concrete, the other two of metal. The flat roof is greened.
