UCD School of Chemical & Bioprocess Engineering – 60th Anniversary Celebration!

Posted Posted in News


On Friday November 18th – over 400 UCD graduates and friends entered O’Reilly Hall to celebrate 60 years of UCD Chemical & Bioprocess Engineering.  Having produced more than 1400 graduates since 1956, the UCD School of Chemical & Bioprocess Engineering is the largest and oldest of its kind in Ireland.

Callaghan Engineering was one of the event sponsors on the night and our Managing Director Donal O’Callaghan (Class of 1973) attended the event along with our Senior Process Engineers Emma McGillycuddy (Class of 2000) and Pedro Rivera (University of Oviedo Class of 1998).  There were representatives from classes covering the years 1957 to 2016, with some graduates travelling from as far apart as the USA, Oman, Saudi Arabia, the Philippines and all over Europe and Ireland.  The MC for the evening was Pat Kenny (Class of 1969). The Chemical & Bioprocess Engineering degree programme is accredited by the Institution of Chemical Engineers (IChemE) and IChemE President Prof. Jonathan Seville attended the event which was hosted by Head of School, Prof. Eoin Casey.

One of the highlights of the evening was the presentation of awards for Outstanding Contributions to Chemical & Bioprocess Engineering to Prof. John Kelly and Paddy O’Flynn both from graduating class of 1957.

Spike Island – “Ireland’s Alcatraz”

Posted Posted in News

The recorded history of Spike Island begins in the 7th Century when it served as a Monastic site, but its chequered past has seen it serve as a Cromwellian deportation hub, a Royal Navy base, convict depot, naval garrison and later a prison, though much of its earlier narrative was also centred on detention and punishment.

Today’s visitor attractions on Spike Island tell its history through the newly constructed interpretive centre which was some 3 years in the planning eight months in construction.

The guided tour begins in the adjacent café which started out as a church and later served as a military drill hall. The tour covers each part of the new interpretive centre which itself consists of 4 distinct buildings, the Café, the Gaol, the Shell Store and the Gun Park.

Known as “Ireland’s Alcatraz”, Spike Island is now considered a go-to destination comparable with attractions such as the Guinness Storehouse and Bunratty Castle. It is anticipated that visitor numbers will exceed 100,000 per year by 2020.

Callaghan Engineering were responsible for the full M&E design which included converting the drill hall into a café and adding a new toilet block. The Spike Island complex has listed status and the design had to ensure limited visible effect on the buildings. Lighting was upgraded throughout, while an internal and external Wifi system was also installed.

Riverview Educate Together – Refurbishment Project

Posted Posted in News


Callaghan Engineering was recently involved in a refurbishment project at Riverview Educate Together School in Walkinstown, Dublin 12. The building was a former primary school built in the early 70’s which had been lying dormant for over 2 years.  The works included a major upgrade of all mechanical and electrical services to modernise them in line with the Department of Education’s technical guidance documents.  The previously dormant heating system was refurbished and recommissioned including reconnection of the gas main to the building.

Under a fast track schedule, four classrooms, an office, staff room, toilets and new entrance area were fully restored, redecorated and handed back to the school for the new school term in a time frame of just 8 weeks.

First Round College Offers – Engineering and Construction points are up

Posted Posted in News

It’s crunch time for all leaving cert grads and CAO applicants as the round one points are released for every course in every third-level institution across the country.  For many, the offers will indicate what they will be studying and where they will be living for the next few years.

Required points offered in Round One reflect the increases and decreases in student applicant numbers for each course.  The areas which saw the biggest increase in student application numbers this year are – construction, nursing, engineering/technology architecture, business & pharmacy.

The points for General Engineering have increased by as much as 75 in UCC, with the biggest demand for places in the construction related sector. Entry points requirements for architecture are up 15 in DIT & 25 in UCD.  Architectural design is up 15 in WIT and Sligo.  Construction management & economics courses have risen between 10-30 points and property and quantity surveying is up by 20 -30 points in DIT and GMIT.

Apple to build Irish Data Centre

Posted Posted in News

Planning approval has been granted to Apple for a new data centre on a 500 acre site at Derrydonnell near Athenry, Co Galway. The new facility is expected to become operational by 2017 and when complete will run exclusively on renewable energy. Once operational, it is expected that the facility will employ up to 150 people.

Apple is investing €850 million developing the new data centre which will support its online services such as iTunes and Maps.  As part of the selection process Apple inspected some 25 sites across Galway before deciding on the Athenry location.  The main reasons given for choosing the site were the “uniquely attractive” lands, road quality and the scale of the site which is expected to be more than adequate to cope with Apple’s 15 year plan to build another data centre in the same location.

A number of global tech companies are either in the process of establishing data centres in Ireland or are significantly expanding existing operations in an overall investment valued at almost €3.7 billion. Alongside companies like companies Facebook, Google, Microsoft, IBM, eBay, Vodafone an Yahoo! some less well known names including BT, Eir, EMC and Equinix have data centre operations here.

Ireland has become popular with companies wishing to set up data centre facilities in Europe due to the country’s energy and communications infrastructure, low corporate tax rate and a temperate climate which helps to reduce running costs.

Callaghan Engineering, one of Ireland’s leading consulting engineering & project management firms, is currently involved in multiple Data Centre projects for multinational clients.

CHP Engine

New CHP Plant for Bausch & Lomb

Posted Posted in News

Bausch & Lomb Waterford, being a 24/7 manufacturing facility, chose to install a CHP (Combined Heat & Power) system to reduce energy cost. The facility has steady and substantial electrical and thermal loads (both as steam and LPHW), so they were ideal candidates to benefit from a CHP installation.

The chosen vendor was Edina Power Ltd, and combined with Winthrop Engineering, the facility was installed and commissioned over the past 12 months. The CHP itself is an MWM TCG 2032 V12 gas engine, generating 3.3 MW of electrical power as well as plant steam and hot water. The CHP and steam boiler as well as switchgear and controls were installed within a bespoke building on site. The engine room is soundproofed and has viewing panels that allow visitors to see the engine without entering the room itself.

The engine can be monitored on the site BMS system and is configured so that the maximum energy is harnessed and used effectively in the plant.

Callaghan Engineering were engaged by Bausch and Lomb at an early stage to review and optimise the solutions proposed by Edina, as well as to advise on the best site / system integration options. Our input was incorporated into the final design. The plant is on-line since May 2016 and is providing substantial energy savings for the Waterford plant.
