Chalmerston Farm article

posted 7 Mar 2016, 07:18 by David Mair

There was a article in the Scottish farmer about the set-up at Chalmerston Farm it can be found here. Eggsellent set up at Chalmerston 

Agri Design have been involved from the initial development of the larger 32,000 bird layer shed. We worked on the initial layout optimizing the site layout and levels to be both cost effective as well as practical. We then submitted the planning and building warrant applications that were required and started discussion with SEPA on the requirements of the Pollution Prevention and Control (Scotland) Regulations 2012 (PPC) an application was then also submitted to SEPA for the PPC.

Farming is dangerous.

posted 23 Mar 2015, 09:43 by David Mair

Now that the weather is allowing some work to be done outside please remember to be safe out there. Work on roofs and slurry tanks can be life changing, there are a number of these incidents every year in fact so many that the agricultural sector that has a higher rate of death per capita in the UK. The second place goes to the construction industry so building and maintenance on farm can be a fatal combination, see the below short list of HSE prosecutions. As an industry we need to do more to be safe.

Farm worker’s death leads to prosecution over exposure to toxic gases

A farm owner and his two businesses have been fined for serious safety failings after a 29 year-old worker died following exposure to toxic gases. Two men had been exposed to toxic gases during maintenance of an anaerobic digestion (AD) plant on a farm.

Farmer in court for roof fall failings

A farm partner was fined for safety failings after a worker was seriously injured when he fell through a fragile cowshed roof. He broke five vertebrae and two ribs, and cracked his left leg socket in the incident. He now has limited mobility and has been unable to work since.

Firm in court after worker paralysed in roof fall

A firm has been fined for serious safety failings after a worker was left paralysed when he fell almost four metres through a fragile rooflight. He is confined to a wheelchair after suffering irreparable damage to his spinal cord in the accident as he replaced plastic rooflights on a farm shed.


Ventilation advice Yeo Valley

posted 25 Aug 2014, 10:06 by David Mair   [ updated 14 Oct 2014, 07:14 ]

Late last year Yeo Valley contacted us about there renewable energy project plans. It was the re-roof and instalation of photovoltaic panels. almost two acres of dairy unit have been re-roofed, one acre of which is now PV cells. The panels estimated output per year is 455,440 kWh.

We were tasked with looking at the existing sheds poor ventilation and designing a new natural ventilation system to create a shed ventilated to the best of standards. The ridges were all changed to protected open ridges of varying sizes depending on stock levels in that area. The biggest issues unusually was air inlets, as it is a very large existing multi span large shed the options were slightly limited but we were able to open up the gable end and sides of the building to allow the required volume of air to enter the building without letting any rain in or creating any drafts.

Scottish planning fees increase Nov 2014

posted 22 Aug 2014, 09:47 by David Mair   [ updated 22 Aug 2014, 09:53 ]

The Scottish planning fees will be increase across the board by approximately 5% form the 1st Nov 2014. So for anyone thinking about a new shed it may be worth submitting the application before this date. 

Prior approval planning applications will increase from £74 to £78.

Full planning will increase from £382 to £401, so for a shed over 560 msq the fee will be £401 plus £401 for every 75 msq over 560 msq up to a maximum now of £20,055.

If you would like to discuss the impact this will have on your project please contact us and leave contact details.

New slurry tank
New slurry Lagoon

Agri Design have been involved in a lot of slurry storage systems over the summer months.  We applied for both planning and building warrant for the two stores above. As they are in Scotland they have to be designed and certified by a structural engineer and have building control approval. If you require any additional slurry storage please contact us for any advice, costings, volume requirements, drawings or applications prepared for local authority or environment agency - SEPA approval.

Sort your shed ventilation for next winter

posted 13 Jun 2013, 08:16 by David Mair   [ updated 13 Jun 2013, 08:20 ]

Now is the time for farmers to start thinking about any upgrades required to new sheds to sort any stock health problems caused by poor ventilation. 
Protected open ridge

If you have had stock with pneumonia during this winters housing period or need to use vaccines to keep things under control you may benefit from improving the ventilation in the shed. 

We can produce a report highlighting changes that would help to sort out ventilation issues. See this page on what we would need to complete a report.

Typically for a simple standalone shed the cost would be £100 for the report. The cost to implement the changes or build a new shed to the reports recommendations will obviously vary but in most cases the cost are repaid within a small number of years through, reduced loss of stock, increased weight gain, increased milk production, reduced vet and medicine bills.

New Scottish planning fees

posted 22 Mar 2013, 12:50 by David Mair

The Scottish planning fees will be increasing on the 6th of April. The fees are going up by about 20%.

This increases the fees to the below amounts.

Prior notification - permitted development approval fee £74

Full planning application for an agricultural shed, structure is now £382 for below 540m² and an additional £382 for every 75m² thereafter.

All agricultural building and structures over 540m² require a full planning application.

So for a building 18.3m x 36.6m (60x120ft) the planning fee works out to be £1146

If you would like any advice on planning application fees please contact me.

Class 1 & 2 (Agricultural buildings)

posted 18 Mar 2013, 05:36 by David Mair   [ updated 13 Apr 2013, 15:33 ]

The difference between BS 5502 class 1 & 2 (Agricultural buildings)

The higher the class number the greater the risk that the building will collapse under wind or snow loads.

Therefore class 1 is designed for a 50 year design life and a stronger building than class 2 which is only design for a 20 year design life.

Most farm buildings are designed to class 2, with only buildings with a high human occupancy designed to class 1 (like farm shops). 

After quite a lot of buildings collapsing in the last few winters farmers are asking about different bay sizes 15 ft and 20 ft, thinking that narrower bays will help with snow loading. This in some cases may be the case but the steel and purlin size tends to be reduced to the minimum requirement to only pass as class 2. So a 15ft bay designed to class 2 and a 20ft bay designed to class 2 should both carry the same snow load before collapse. 

If you are worried about snow buildup on a new building you should ask for it to be designed to class 1. A class 1 structure will take about a third more weight than class 2. Also remember that the area of country you are in and how high above sea level all have an impact on the structural design. Some shed builder supply a standard kit buildings but it may not be suitable for your site if you are in an exposed site or high above sea level. Contact us for further information or help in making these important decisions.

New silage clamps

posted 4 Mar 2013, 10:08 by David Mair   [ updated 7 Mar 2013, 03:22 ]

Roofed silage clampAny farmers that will require additional silage storage should already be thinking about it. 

To have it build for this years silage season planning and building warrant applications should be made very soon to allow time to get the application passed and the builder onsite as early as possible. If the silage clamp is cast in-situ concrete construction at least 30 days should be allow for the concrete to fully harden before filling with grass. 

For further information, help with planning or building warrant applications or just general advice with designing your silage clamp please contact me.
