Structural Engineers Declare

Posted on Tuesday, July 16, 2019 by Rebecca Dawson

It has been established that building and construction practices contribute to nearly 40% of energy-related carbon dioxide (CO2) emissions which are impacting destructively on our natural environment. The question being asked is 'how can our industry meet the ever increasing demands and requirement of our expanding society without pushing the Earth's ecological boundaries?

There needs to be a to be dramatic shift, industry-wide to strengthen our working practices and habits, to create structural engineering outcomes that have a far more positive impact on the world around us.

The Happold Foundation is spearheading multiple campaigns to unite engineering companies to ensure the sector is doing everything it can to minimise its impact on the environment. Patrick Ryan Associates along with other UK Engineering Practices are now a signatory on their first campaign  Structural Engineers Declare pledge committing to be part of a collaborative group striving to be part of the solution rather than the problem.

RIBA Award Winning Project

Posted on Monday, July 15, 2019 by Rebecca Dawson

We are delighted to hear that a project we worked on Facade Engineering Consultants and glazing designers, Kenwood Lee House has recently been awarded RIBA London Award 2019.

The back of the building is built of numerous large glass panels, the middle panel spanning the double height of the upper floors allowing the owner to have uninterupted views of the woodlands at the rear.

'The rear façade, on the other hand, is an exercise in modernism, with a severe curtain wall of glazing interrupted only by a decorative frill of brise soleil.' RIBA 

Designed by Cousins & Cousins, this luxurious family home has also been Longlisted for RIBA House of the Year 2019 & 2019 Shortlisted New London Awards

We welcome a new member to our team

Posted on Monday, October 22, 2018 by Rebecca Dawson

A few words from our new Graduate Facade Engineer...

My full name is Elizaveta, but everyone calls me Lisa or Liza. I am 23 years old and I come from Estonia and I speak Estonian, Russian and English, also trying to learn German but it is still very basic.

I moved to the UK 4 years ago for uni. I've done an Architectural Engineering degree in Cardiff University, Wales. After graduation I've completed one year of work experience which I really liked and it allowed me to see the industry of Facade engineering from inside. It also gave me the understanding in what direction I want to develop professionally and this is what brought me to Patrick Ryan Associates, and I am very happy about it!

In my spare time I like going to various music concerts, art galleries, theatres or do anything outdoors. I consider myself to be a quite active and curious person so I'm always up for any sort of activities.

In the past I've done many years of violin class, various dancing and art classes. Also, when I was 16-19 did work with kids (summer camp leader and volunteering in children's house) and travelled in Europe for youth exchange projects.

Since I've moved to the UK I've met amazing friends that are now my family away from home and I very appreciate it.

20th Anniversary Summer Party 2018 

On 14th July, PRA celebrated it's 20 Year Anniversary at our Summer Party BBQ 2018 with our team and their families, our consultants and our clients, past and present.  Patrick and Mary hosted a wonderful BBQ and the afternoon was filled with great food, wine and conversations.

The 'DISCO' bouncy castle proved to be a great success and was enjoyed not only by the kids but by the energetic members of our team as well!

The company was started by Patrick and was run out of his home, with the help from external consultants in 1998. 

At 2018 we have a team of 11 members of staff, over several departments, and is continuing to grow into a multi-disciplined team.

Thermal Bridging in Rainscreen Cladding

Posted on Thursday, May 31, 2018 by Anri Doda

A simple rainscreen cladding support system typically consists of ‘helping hand’ brackets. These are the backbone of any rainscreen cladding system and are fixed to the substrate at set vertical and horizontal separations. A layer of insulation is then fixed to the substrate, and where the brackets are placed they penetrate directly through the insulation, forming what it is called a “Point Thermal Bridge”. Aluminium ‘L’ and ‘T’ profiles are inserted into the brackets, lined, levelled and fixed. A ventilated layer behind the external façade material ensures the risk of condensation is minimised as well as dissipating solar gain in the building.

Thermal Analysis on Facades

Posted on Thursday, Nov 02, 2017 by Anri Doda

To achieve good sustainability in our buildings we need to consider heating, ventilation, solar gain, building use, choice of materials and building form, amongst others. Very good thermal separation between inside and outside is necessary to obtain the required internal conditions and optimum energy efficiency. To achieve this we must avoid thermal bridging through the wall construction.
