Agricultural Engineering

Just like agronomy, agricultural engineering includes several intervention sectors in agriculture. UDA offers a wide range of agricultural engineering services meeting the ever evolving needs of its clients. The team is composed of experienced and versatile agricultural engineers, working jointly with other specialists, the client and other project stakeholders, in order to design personalized, lasting and innovative solutions. The various agricultural engineering sectors covered by UDA are: soil conservation, surface and subsurface drainage and water management, manure treatment, energy production, agricultural machinery and other infrastructures. In addition to the implementation of projects, UDA carries out prefeasibility and feasibility studies.


  • Subsurface and surface drainage and associated components;
  • Design of measures for the protection of agricultural environment;
  • Management of surface water in agricultural environment;
  • Technical requirements study for the installation of agricultural buildings or facilities;
  • Technico-economic study (prefeasibility, feasibility);
  • Banks, dykes and embankment;
  • Research and development.

Influence of Drinking Hoppers and Bowls

For a long time, standards for the storage of hog manure have mostly been based on data from abroad. The development of new types of drinking-troughs showed that their use resulted in major feed water loss reduction, which in turn led to an important diminution of manure storage needs. In order to quantify these savings, UDA was mandated to compare manure production issued from hog raising facilities equipped with “dugs” with the one issued from facilities using drinking-hoppers or drinking-bowls. Five installations of each of the three types were monitored for a twelve-month period and the results conducted to the calculation of the real savings in manure storage capacity needs in the order of 30 %.

Based on these data, new provincial manure storage capacity standards were established according to the type of drinking trough in use, which allowed a substantial saving for the agriculture producer as well as subsidy reductions.

Relocation and Conception of the Dairy Complex, AAC Lennoxville

The relocation of Agriculture and Agri-Food Canada (AAC) dairy complex in Lennoxville required a detailed analysis of the requirements that led to the development of a “Functional and Technical Program” (FTP) as well as a cost evaluation.

To prepare this FTP, UDA consulted researcher in groups, in order to specify the research priorities and technical needs required to meet the very high standards of this team.

With the support of specialized partners, UDA established a FTP, combining management and operational breeding needs for a herd of 125 dairy cows, while providing all functionalities commanded by the various research projects conducted on these animals.

An evaluation of the costs associated with the whole project and other various options was also part of the mandate. The FTP led to the call for tenders’ stage for the preparation of the construction documents.

Greenhouses Relocation Study, City of Montreal

For several years, the City of Montreal has been operating an important nursery located in the city of L’Assomption. However, the production of flowers and plants was still carried out in the greenhouses of Montreal’s Botanical Garden. UDA was then mandated by the City of Montreal to realise a study on the relocation of the greenhouses complex and its integration to the L’Assomption nursery buildings.

UDA’s responsibilities were to clarify the specific needs in terms of production and to propose various integration options to the L’Assomption buildings and activities.

The City of Montreal integrated the results of the preliminary economic study as well as the construction and operating cost evaluation to its administrative decision process.

Modifications of Subsurface Drainage System Plans, Ultramar

As part of the Ultramar pipeline project, between Levis and Montreal-East, UDA designed the required modifications to the subsurface drainage systems of farm lands (approx. 70 km) crossed by the pipeline.

UDA’s mandate was to locate, gather and analyze the subsurface drainage system drawings of each farm (more than 250), to evaluate the impact of the pipeline project on subsurface drain tile system, to design the required modifications and to ensure installation supervision during construction works. UDA was also responsible to meet all concerned landowners to present the proposed modifications.
