Cheers jrb, it'll will look better when/if the north stand is complete

Apologies as this may be a rather long and dull post but I wanted to check on the new roof and impact on noise!

I've had a look at the Committee Report that was produced prior to the consent for the expansion. Within that document is a summary of the noise report that was produced. Because of Environmental Health regs a planning condition has been imposed and modelling took place to ensure that noise emitted from an expanded stadium did not exceed acceptable levels... I've taken some extracts below but in summary;

It has been stated that the geometry of the new roof and absorption will ensure that noise is not higher than is currently experienced (this is measured at the nearest residential unit). It does state within the report that the roof will be re-designed to remove previous absorbing material. Basically, there will not be an increase in noise heard at the nearest residential unit from any stadium expansion. It is unclear to what extent that is because of the use of absorbent material within the roof design or because of the new geometry of the roof where noise will resonate down to the pitch as opposed to escaping out of the stadium... I'm hoping (and I would expect) it's because of the geometry of the roof rather than material make up of the structure. I reiterate that this is all based on the noise levels heard at the nearest residential unit and it is not based on noise generated within the stadium. I'm again of the hope that the club has not had to use absorbent material in the roof again and instead through a combination of the geometry of the new roof and perhaps abating material within the stand itself, the noise levels can be contained.

Here are some snippets from the committee report;
The existing low slung roof profile at the north and south stands measures 12 metres
at its lowest point rising to 26 metres. The highest mast measures 35 metres. The
proposal will see the raising of the height of both these stands increasing the height
to 38.5 metres with the highest proposed mast reaching 57 metres.

The changes to the height of these stands will inevitably result in the loss of the
sweeping roof profile, which is currently symmetrical, and increase the overall scale
and massing of the stadium. Furthermore, the proposed alterations to these stands
will result in a slight increase in height over the east and west stands (which measure
32 metres) by 6 metres.


Noise/vibrations
The Environmental Statement provides supporting documentation on the effects of
the proposed development on noise and vibrations. The consideration of such
matters is a key requirement for policy DM1 of the Core Strategy along within extant
policy DC26 of the UDP. This approach is also outlined within the NPPF which
seeks to avoid noise giving rise to significant adverse impacts on health and quality
of life as a result of new developments.

The noise assessment details noise modelling that has been undertaken to
determine the noise egress levels from the site. The modelling has taken into account
the changes in geometry proposed for the north and south stands, changes in the
noise levels as a result of the increase in capacity of the stadium and the reduction in
the sound absorption to the underside of the north and south stand roofs.


The sound measurements recorded during a match day with the current capacity of
the stadium ranges between LAeq, 15min 59 d B and LAeq, 15min 62 d B with the main
sources of noise coming from road traffic, crowd noise and PA announcements.

The modelling within the Environmental Statement indicates that noise egress during
a match from the expanded stadium is not expected to increase the ambient noise
levels outside of the nearest noise sensitive premises. This is due to the adsorption
capacity of the new roof and its angle. (Does absorption capacity relate more to geometry or materials???)


The LAeq, 15min d B levels are anticipated to be LAeq, 15min 61 d B for the south stand
and LAeq, 15min 62 for the fully extended stadium. This is as per the current conditions
at the stadium. As such, there will be a negligible impact from noise egress during
football matches as a result of the south stand only and the extended stadium as a
whole.

Sound pressure measures were taken outside the Robbie Williams Concert (June
2013), Coldplay (June 2012) and Bon Jovi (June 2013). At the Robbie Williams Manchester City Council Item 15
Planning and Highways Committee 13 February 2014 concert sound pressure levels ranged between LAeq, 15min 67 d B, LAeq, 15min 75 and LAeq15min 73 d B. At Coldplay the sound pressures ranged between LAeq, 15min 72 d B and
LAeq, 15min 73 d B whilst at Bon Jovi the levels ranged between LAeq, 15min 66 d B and
LAeq, 15min 68 d B.

The environmental noise modelling for concerts shows a similar negligible result to
football matches with the geometry of the new roof reducing noise egress levels
during concerts by 4 dB to the residential properties across Ashton New Road.


In order to ensure that the noise egress from the stadium during events remains
negligible, it is recommended that prior to the first use of the extended stadium (or
the south stand) that sound checks take place to ensure that the LAeq, 15min 75 d B is
met.

Overall, the noise output from the operation of the stadium, for football and concerts,
will be similar to existing conditions. Planning conditions will be used to control these
conditions and ensure that they are not exceeded in order to protect the amenity of
the surrounding residential properties.

Speaking to someone today who I fully trust who told me that the athletic stadium and car dealership have both been purchased and Asda is also on the horizon.

The athletic stadium definitely and possibly the Merc garage will be converted to car parking spaces.

This sounds like bullshit, as if the council would allow us to buy an athletics stadium and turn it into a car park.

Interesting stuff, that. I never thought that the escaping noise is an issue for neighbours. Whilst what you've post ed is ambiguous and the mentions of 'sound absorbing'' a little worrying, the points about 'noise egress' are encouraging, as is the point about the shape of the roof.

Putting a planning application together, you'd expect City to talk up the lack of impact on residents.

This sounds like bullshit, as if the council would allow us to buy an athletics stadium and turn it into a car park.

They probably would if we were rebuilding it somewhere else on the campus, it would make sense to have parking there and the athletics stadium relocated in the campus. It would free up the car parks on the collar sight.

Do I have to effing write it again ASDA IS NOT BEING BOUGHT.

You would but I'm in the construction game and noise requirements are extremely stringent - they will have done full modelling to prove the levels received at the nearest residential unit and it will also be conditioned so that they have to achieve the dB level stated. Obviously the work they will have done will ensure that noise will not be an issue and though I'm no expert and haven't seen the report (though I'm going to try and find it on the portal) - I'd imagine that because the angle of the roof is down to the pitch, the noise will be filtered away from the nearest residential plots without the need to use absorbent material. I think the new south stand is going to be loud!

Absolutely fantastic photo's as always JRB mate, can't wait till those bloody sides are finished!.

& that missing top roof panel has been sending my OCD into overdrive for about 2 months! It's gonna look bloody marvellous when finished.
