12th April 2017 – Food and other waste collections - Carlos Novoth of Stroud District Council

Carlos Novoth is Public Spaces Manager at Stroud District Council, His deputy Mark Graham gave the presentation.

Mark told us how successful the new coloured waste collection bins have been and how poorly designed many waste collection areas for apartment blocks.

Here a are a few statistics

Since changes were introduced in the Stroud District:-

  • The total amount of waste decreased
  • Dry recycling has increased
  • Three quarters of food waste captured
  • Landfill has almost halved

(2150T/month to 1100 T/month).

Stroud are now recycling over 500 tonnes of food waste per month (equivalent to 6,000T per year) which is being sent for anaerobic digestion.

8th March 2017 - Building Regulations Part Q - Andy Jones, CDC Building Control
Part Q, a little note about Part R and an introduction to Partnerships.

As always keeping up with current legislation and building regulations is vital. Andy Jones and Paul Bowley talked to us about part Q and its implications. Apparently this and applies to new dwellings at present. Part R

Requirement QI states:    Reasonable provision must be made to prevent unauthorised access to:

  • Any dwelling
  • Any part of a building from which access can be gained to a flat within the building.

Approved Document Q is designed to ensure the prevention of unauthorised access to dwellings (including flats). As part of this, doors and windows or roof lights which could be accessed will need to resist physical attack by a casual or opportunist burglar.

8th February 2017 - The Oak Frame Carpentry Company – Tim Potts

Tim Potts has a wealth of experience in manufacturing oak frames for buildings.

“I will be presenting on the Nave Ceiling and Roof at St David’s Cathedral. This is a unique and spectacular 16th Century timber structure with a lot of fascinating detail. With a carpenter’s eye, I was able to find and interpret hitherto unrecorded evidence to reveal the story of its construction and installation.”

11th January 2017 - Telebeam – Loft conversion system

Telebeam Ltd told us all about their clever loft conversion and flooring system. Mr Digby Rowsell did doing the presentation.

Essentially this is a steel frame installation that allows even trussed rafter roof constructions to be adapted easily to accommodate usable space in the roof void. With an increasing trend towards expanding existing homes in preference to moving this is a very useful system. See also

15th December 2016 - Social History of Pub Signs by Angela Panrucker

Angela is a member of the Inn Signs Society and has expert knowledge of Gloucestershire pub signs.

What do they all mean?

The BDA Christmas meal was enjoyed by all who attended and Angela delivered a polished presentation increasing our knowledge of the derivation of many pub signs and names.

For example

Kings Head
“Prior to Henry VIII’s breakaway from the Church of Rome, many inns were named the Popes Head. In order not to irk the king, astute innkeepers ensured they had their signs repainted in homage to the king instead. The variety of monarchs portrayed on pub signs provides rich pickings for a speciality subject.”

9th March 2016 - Presentation of the local plan for Stroud District by Conrad Moore, Principal Planner

Since 2009 Stroud District Council has developed the new Stroud District Local Plan. It was formally adopted on 19th November 2015 and replaced in its entirety the saved policies in the 2005 Stroud District Local Plan. It is a very different Plan in terms of approach and content. It is now the statutory Development Plan for the District. It sets growth requirements for at least 11,400 dwellings and 58ha of employment land for the Plan period 2006-2031. The NPPF (Paragraph 12) states ““Proposed development that accords with an up-to-date Local Plan should be approved and proposed development that conflicts should be refused unless other material considerations indicate otherwise”.

Here is a link to the Stroud District Council webpage dealing with the plan

10 February 2016 - The Javelin Park Incinerator pros and cons and alternatives - Tom Jarman of R4C

This is something that potentially affects all of us living and working in the area with impact on the massive new development now planned around and north of the M5 junction 13, the so-called Westington which could be influenced by fears of what may escape from the long debated incinerator at Javelin Park. Environmental concerns, water contamination, blight on property values, etc etc. But the rubbish we all merrily chuck out on bin days must go somewhere.

The speaker was Tom Jarman of R4C

11th of November 2015 - Chris Uttley spoke on green SUDs in the Stroud valleys

This session was completely complimentary to our recent presentation, and relates to run off management upstream, to prevent flooding lower down waterways.

Chris works for Stroud District Council and is pioneering a way of managing flood risk in a river system by building many leaky dams of felled trees. This technique in in contrast to the national policy of land owners being required to keep watercourses clear of obstructions. He has show this leads to excessive river bed erosion and higher levels of flood in lower reaches of a river system.

An opportunity to hear Rob Sutton, archaeologist and heritage consultant, at Cotswold Archaeology discuss the work they do and how their expertise can add value to your construction projects.

Following a short introduction to the concept of ‘heritage assets’, the presentation will aim to provide the background to the legislative and policy framework in which we, as designers, builders and occupiers operate in England. The presentation will look at archaeology and the (art and) science of prospecting for buried remains. The various techniques adopted by the profession will be explored, utilising real project examples to examine what is often required by Local Planning Authorities to allow for applications to be determined. The final element of the presentation will look at the way important buried remains influence the very shape of development proposals.
