OBConstruction Leads New Dairy Project At Greenmount 



OBConstruction has just completed the largest cutting edge agricultural project Northern Ireland has experienced to date. The engineering and construction of a new learning and development dairy unit at Greenmount Agricultural College, with the company as main contractor, has completed within programme and handed over to CAFRE this week. OBConstruction has had years of industrial and agricultural experience, and were appointed for installing the state of the art facilities for the college. The building is portal frame construction, 4500m2 in total with a steel clad, trussed roof and masonary envelope. The works comprised of a major site clearance and reduced dig before constructing below ground insitu concrete tanks. The cubicle house was designed to facilitate 150 cows and caters for various groups of cows- heifers, dry cow, high yielding and fresh calved. Both portal frame buildings have ventilated light ridge and ventilated curtain, this ensures temperatures are controlled and cows remain comfortable at all times. The cubicle house has a single rail feed barrier. The cubicles contain mattress, all of which have been designed for optimum comfort. Three layers in the mattresses ensure soft lying areas, supporting the correct resting positions and increase yield. 


With cow welfare as the main proprity, grooved rubber matting increases resistance for hoof grip and enhances standing comfort. Automatic scrappers are used in passages and the collecting yard to deposit slurry in 2 small tanks and channels, which is removed for anaerobic digestion. Grooved and textured concrete slabs were used instead of slats. This ensures reduced ammonia volatilization from floor surfaces, reduced GHG emissions and greater slurry efficiency. End and central feeding passages ensure ease for feeding, accompanied with automated feed bridges to keep feed clean whilst cows are in transit to the parlour. A rain water harvesting system was implemented, pumping system, pressure/volume washing system with emphasis placed on electrical efficiency to product less CO2. The milking parlour houses specialist dairy equipment for student training facilities with a 16 point doubled up and large collecting area with automatic backing gates to the rear.  




Cow handling facilities offer automatic hoof washers, automatic weigh bridge, clipping and A.I crates, hoof trimming crush, holding pen, galvanised 3 way automatic drafting gates, herringbone crush and race (all handling facilities were manufactured in house by OBConstructions specialist team) and trailer loading facilities for animal transport. The bull pen was implemented with operator safety central to the design. The maternity wing offers post and pre calving pens, treatment and recovery areas and twelve indivdual calving pens.  







The reception and plant block contains visitor changing facilities, toilets, chemical store, plant room, tank room, offices and vetinary room. Specialist finish was applied to the front of this building using cedar boarding and natural basalt stone cladding coupled with a larged glazed facade. There is a VIP entrance, viewing area and conference room for guests. This two storey building contains a lift to enable disabled access onto the first floor. Car parking facilities were created accompanied by landscaped and paved areas. 


Company Director Pat O’Boyle states “We were delighted to play such a key role in this very exciting project. It is our hope that this new facility and research carried out therein will be of benefit to the farming industry in Northern Ireland.”
