3.0 Introduction and scope This document has been prepared to describe the outline methods of operations and techniques proposed for the controlled dismantle and demolition of the following Ponds buildings at Bradwell. There are 11 buildings in total to be demolished. The buildings have been split into 3 Demolition groups and will be demolished in the sequence as shown below. Group 1. 62-Iso container loading bay X4-The flask loading bay 40-Active waste handling building 39-Final delay tank building Tank room on the roof of building X5 Group 3. 73b-Active waste vaults vent plant building south 74-Incinerator building 73a-Active waste vaults vent plant building north Group 2. 150a-Elevated walkway 150-Sub change room 101-Fed drum store The buildings have been left in a ‘cold and dark’ condition. All plant and equipment will have been removed from the buildings. All water and power supplies to the buildings will have been have been disconnected. The buildings will be dismantled/demolished using excavator and various attachments. The demolition waste arisings will be segregated at source removing all re-bar and steel which will be placed into the metal waste skip. The concrete and brick spoil from each individual building will be transferred to an area of site outside the Radiological controlled area (RCA) as directed by Magnox The concrete and brick spoil will be crushed to 6F2 and stored as agreed with Magnox. It is anticipated that some residual asbestos may be present in some of the buildings and may be encountered during the demolition phase. Squibb group personnel will be asbestos awareness trained Buildings X4 & X5 are built as one building and require separation, therefore a temporary designed scaffold will be erected to support building X5 prior to the demolition of building X4. The scaffold facing building X4 will be fitted with ranch boards to which 1000guage polythene sheeting will be fitted so to seal off building X5 prior to demolition. The scaffold will remain in situ until a permanent designed structure has been agreed and installed. The scaffold design and erection works will be carried out under a separate RAMS.


4.0 Environmental Management. The demolition of the pond buildings within this RAMS is scheduled to take place from September 2016 through to January/February 2017. Advice has been taken from Kayleigh Cheese (Natural England) and also from Tony Stones (TSA Ecology) regarding the potential impact demolition works would have on overwintering birds. The overwintering period for a number of bird species especially water birds, waders, wildfowl is from October to March.

Photo1. Location of demolition operations.

The area highlighted in the photograph above shows the majority of the buildings to be demolished on the east side of the ponds complex.

There are a few small buildings to the west side of the ponds which will be very quickly demolished due to their size.

Natural England have raised a number of issues which they would like addressed within the RAMS.

How are the buildings to be demolished and by what machinery?

The machinery is listed in section 8 and the method of demolition has been detailed for each individual building.

The demolition method has been written to exclude the use of pneumatic hammers in favour of the concrete crusher as recommended in the Magnox 2013/2014 Bradwell Site Environmental Management Plan.


Hours of operation?

The hours of operation will be approx. 7.30am to 5.30pm. No demolition works will commence until daylight and demolition operations will cease prior to loss of natural light.

How will the waste from demolition be disposed of?

What access routes are to be used?

What times will rubble be taken away?

What form of transportation will be used?

The demolition spoil will be transferred from the RCA to an agreed location within the Bradwell site perimeter using a tipper lorry. The waste will be transferred a short distance only carrying the demolition spoil from each individual building.The waste will be recycled and reused as required by Magnox. The waste will be transferred as required during normal working hours. At no time will waste be transferred at night.

Birds could be affected by movement and lighting.

The lorry used on site will be travelling short distances only (within site boundry) The excavator will always be moving in slow motion and covering very short distances. All plant and equipment will be turned off at all times when not in use. Plant operators to be ever mindful of the environmental issues when revving engines. No works are to be carried out outside of normal daylight hours so avoiding light spill in the direction of coastal areas.

What noise will be produced?

The noise of the excavator at source will vary between 85 decibels and 110 decibels at peak depending on the operation. As stated previously concrete crunching/crushing will be used instead of concrete breaking.

The noise levels at 100 mtrs from source will read at 70 dB(A)

The noise levels at 200mtrs from source will read at 63.98dB (A)

There are areas of interest close to the site. Pewet Island in the estuary to the north west of the site is a high tide roost site (TSA Ecology report-26/08/2016) See map on page 8.

The demolition works are being carried out to the west side of the two reactor buildings. See photos 1& 2.


Photo 2. This photo shows the considerable green belt to the east and west sides of the site.

Jetty Demolition area

Reactor buildings N

The reactor buildings will act as a natural noise barrier between the demolition site and Pewet island. The Island is also a good distance from the demolition area. There is a considerable green belt to the west and east of the station. See photo 2.

Photo 1 shows the north shore to be approx. 200 mtrs from the demolition site. The (TSA Ecology report-26/08/2016) states that the most of the effects of demolition activities (If Any) will be to the north and north east of the site.

The Bradwell Site Environmental Management Plan 2013/2014 gives a brief description of the area to the north and northeast.

“In contrast the section of dyke that lies immediately to the north of the power station supports dense common reed with little surface water at all. The section to the east of the power station also holds little or no water and supports a mosaic of dense reed habitat and grassland dominated by sea couch”.

Looking closely at photo 1 I do not believe that the area north of the site would be the prime site that would attract overwintering birds with so much prime marsh ground on which to feed and rest to choose from. However, it would be very interesting to carry out surveys of the area before, during and after the works.


Information needs to be included regarding dust and how it is to be controlled.

Information on dust has been addressed during every phase of demolition and also in the risk assessment. Damp down as required is a statement used for each and every building. As required is taken to mean just that. We do not want to be using too much water which is a waste.

Natural England assumes that there will be no discharges associated with these works, If there is then detailed information will be required.

The only discharge envisaged will be surface water which will be generated during the damping down process during demolition. In order to contain any particulate, Squibb Group will position square spill pads across the surface water drains. The drain cover will be lifted, the pad will be positioned and the drain cover replaced. This will form a seal allowing only water to filter through the pad.

5.0 IDENTIFY GENERAL SITE HAZARDS

Vehicle Movements

Beware of vehicle movements on site and keep to designated pedestrian routes All plant must be fitted with reversing alarms and accompanied by banksman

Trip Hazards

Maintain good housekeeping at all times and ensure work areas are cleaned up at regular intervals

Keep pedestrian walkways clear at all times

Noise

Noise levels will be monitored throughout the project At exposure levels of 85dB (A) Squibb group will ensure that ear protection is worn at all times

Dust

During demolition works dust will be minimised using dust suppression methods

Light eye protection is mandatory on site for Squibb operatives.

Harmful

Substances

COSHH and Material Safety Data Sheets will be available for all residual hazardous materials

Asbestos

Areas containing ACM’s will have been cleared and removed by licensed asbestos removal operatives.

The finding of any further suspect materials or asbestos containing materials will be reported to Magnox. Demolition works will stop until the asbestos issue has been addressed by a licensed contractor.


Electricity

Prior to commencing demolition works all electrical supplies should be isolated. If you have any doubts about electrical supplies, stop work and consult with the Site Manager.

Certificates of electrical isolation to be passed to Squibb site manager prior to commencement of demolition works

Manual Handling

Always consider what you are going to lift and how you are going to lift, there may be another way

Always consider mechanical methods such as forklifts or other types of plant.

Working at Height

If you believe your work will create an unprotected edge then stop and raise this concern with your supervisor or the Site Manager so that a suitable system can be put into place.

Never walk away and leave an open edge or hole unprotected.

Electrical tools

All electrical tools will be inspected prior to use to ensure that they are in good working order and fit for purpose.

Always use the correct tools for the task being carried out

All tools, cables will be 110v and carry in date inspection tags (PAT)

Radiaton Contamination

This work is being carried out on a Nuclear site

13.18 BUILDING 40 THE ACTIVE WASTE HANDLING BUILDING (7.4m wide x 22.3m long x 8m max high) The road to the east of building 40 will be temporarily closed and managed whilst ensuring that previously agreed emergency access/egress measures are maintained. Demolition will start at the south end of building and continue in a northerly direction Position excavator on the X4 slab facing north. Position banksmen with radios.

13.19 Protect protruding pipework system to the east side of building 40 using 8’x4’x1” plywood sheets prior to start of demolition. See figure 1.

13.20 The jaws will demolish the south end wall first, then steadily crunch through the roof and first floor slab section by section trimming the east and west supporting walls as the excavator progresses in a northerly direction. Damp down as required Continue as above until the two story section has been demolished. Continue to demolish the lower section of building 40 in the same manner trimming the roof and wall sections in a northerly direction as far as the south wall of building 39, until building 40 has been completely demolished. See photo 3. The ground floor slab and supporting piles will be left in place

13.21 Periodically excavator works will stop whilst any burning works take place (re-bar) Process the waste separating any steel. Transfer all steel to the metal skip.

13.22 Building 40 is the largest of the buildings to be demolished. The concrete and brick spoil from this building will be temporarily stockpiled on the X4 slab area. The spoil will be graded and compacted by the excavator. The reason for this operation is that the excavator will use the ramp in order to gain extra height for the demolition of the Tank room which sits on the roof of building X5. See figure 2 below.

Low (2)

Residual Risk Rating = Likelihood of Occurrence x Severity of Hazard High = 9, 6 Medium = 4, 3 Low =2, 1 Likelihood of Occurrence Low (1) May occur in time. However, hazard exists infrequently or hazardous event occurs very infrequently. Low expectation of occurrence. Medium (2) Likely to occur in time. Hazard exists intermittently or hazardous event occurs occasionally. It may be useful to define by exclusion, {i.e. clearly not' High' or 'Low' may be the most practical approach}. High (3) Likely to occur imminently or in the very short term. Hazard exists permanently or hazardous event occurs frequently, or much evidence of previous harm.

Severity of Hazard Low (1) Hazard resulting in minor injury requiring first aid treatment only. Minor consequential loss potential to both individual and organisation. Medium (2) Hazard capable of resulting in personal injury/illness requiring brief absence from work. Medical attention required. But ... Again, defining by exclusion, i.e. it simply isn't obviously 'High' or 'Low'. High (3) Hazard capable of resulting in death, severe injury or illness. Major consequential loss potential to the individual and organisation.

GENERAL

HAZARDS ARE NUMEROUS AND CAN BE EVERYWHERE THE KEY IS TO REMEMBER YOUR TRAINING. TAKE NOTE DURING SITE INDUCTIONS BE EVER VIGILANT AND WATCHFUL, DON’T TAKE CHANCES, IF YOU ARE NOT SURE ASK. REPORT ALL NEAR MISSES. NEXT TIME IT COULD BE AN ACCIDENT.
