2. Existing Conditions.
Details of the existing site and its previous use are well researched and documented by the
Architects. None of the reports suggest the presence of any serious residual Health and
Safety risk due to its previous use.
Existing Play Ground
New car park and emergency track formed over the fill area of previous school, trial pits
required to check for ground obstructions and contamination.
Weston All Saints Primary School is located on the Western side of Bath the site is situated
on a significantly sloping site retained by existing retaining wall structure bounding the
Lansdown Lane
The site is located in a residential area between Vernslade Lansdown Lane and Broadmoor
Lane
Access to the school is from 2 pedestrian locked gates on Lansdown Lane both are opened at
8.15am each day and closed 9.30am by the caretaker and opened in the afternoon at
3.00pm and closed again at 4.30pm.
There are further access points in Broadmoor Lane, 1 vehicle and pedestrian access point to
Staff car park controlled by hand held sensor and coded lock and closed by staff on entry.
The main school entrance is located a further 100 yards North west along Broadmoor lane
this is controlled by code and by contact by microphone to the School reception.
It is intended that all Site Traffic will be via the first Staff entrance on Broadmoor Lane with
the existing gate access system in place, the Site compound will be within the School locked
area with gates controlled by site staff locked at all times to prevent children from entering
site compound.
Access for construction vehicles through Vernslade was considered. However as this route is
through a narrow residential street, where cars park either side of the road, it was deemed
unsuitable. The addition of construction site traffic would cause high levels of disruption and
congestion, leading to unnecessary increased risk to public safety.
Existing services- Information on the status of existing services is not entirely accurate, Prior
to commencement there is a requirement to carry out investigations to locate and protect
existing services Gas, Water drainage, communication that cross the site these must be
isolated and made safe prior to excavations commencing.
There is no existing wildlife management scheme; existing trees to remain will require
Protection.
At the request of the Highways Authority there are some 5 No. trees to be removed in order
to accommodate the revised access road works.
3. Managing the Construction Work.
The Main Goal of the Management of the works is to complete the project in accordance
with the requirements of the current Health and Safety legislation current Health and Safety
Guidance and Industry Good Practice without endangering the Health, Safety and Welfare of
the Pupils, Staff, Visitors at the school, all personnel engaged in construction of the project
and any person who may be passing by the site by foot, or any other means of transport.
All Construction and delivery vehicles will be adequately managed.
Orders will state strict delivery times which will be restricted to avoid peak traffic congestion
times, namely between 8.30am – 9.30am during the morning drop off period and 2.30pm –
4.00pm during the typical school collection times.
This schedule will form part of all subcontract agreements.
Material storage will be accommodated within the site compound area. A combination of
secure containers and hardstandings will be provided. . A forklift will be provided to
distribute materials, contained within the compound.
All dedicated pedestrian routes will remain protected during the works, but it is vital that
where possible pedestrians are kept away from the site.
To manage the risk at the point of pedestrian crossover at the end of the drop off bay
directly across the ‘secondary’ site entrance, temporary speed humps and a temporary
raised zebra crossing will be installed.
In addition ample large ‘high impact’ visual construction traffic warning signage and
vehicular speed limits will be in place leading up to this junction.
Scheduled deliveries will be escorted by a banksman from the main road along the shared
access route, as a means to mitigate risk.
The 1 footpath off Lansdown Lane (southern) will remain open throughout the project
The northern access will be suspended as shown on Appendix 1
This gate will remain in total control of the School throughout the project and will remain
outside the site boundary
The site compound will be as shown in Bush Architects Drg L 012 rev H, copy provided in
Appendix 1. To accommodate staff parking requirements for the duration of the
construction works, the proposed drop off zone is to be temporarily used for this purpose.
The compound has been set out to allow sufficient room for staff vehicles to safely occupy
this area and provides room for turning.
Appropriately the construction of the drop off zone has been programmed to take place
during the summer holiday period, in readiness for the start of the September 2014 term
dates.
Where necessary temporary fencing (Heras Metal) will be erected to secure the site with
access gates kept locked and never left open
Site accommodation including toilets canteen and office will be set out dependent on
ground conditions but generally as per attached plan Appendix 1.
Arrangements will be made for the Site manager to be able to open the school gate on
Broadmoor lane in cooperation with the School caretaker to allow delivery of materials,
24hour notice will be given to the site team to allow communication and delivery.
Further – delivery drivers will be instructed to contact the site management team 15
minutes ahead of arrival, to allow the site team to attend the school gate and prevent
congestion off site.
Where possible and practical all delivery vehicles will be asked to journey to the project via
Lansdown Hill from the M4 junction, and asked to vacate the same route to make no impact
on the Bath Traffic.
No visiting cars or Vans are to park on the Lansdown Lane, Broadmoor Lane or any other
residential area.
All construction vehicles will be afforded parking on site, within the site compound area as
defined by Bush Architects Drg L 012 rev H.
Delivery vehicles will also be limited to fixed wheel base lorries, (no Articulated lorries)
All vehicles entering and leaving the project will be controlled and supervised by site staff.
The Site working hours will be 7.30am-6pm Monday – Friday
7.30-1pm Saturday
The construction methods are traditional timber frame techniques,
Foundations and services
Substructure , brick and blockwork
Slab formation
Scaffolding erection

The biggest challenge will be erecting the timber frame by crane. The intention would be to
utilise the existing play/ sport area as a crane base, this will be accessed by the construction
of the emergency roadway to the New School early in the project this will provide safe
conditions for the crane and good access to the building through out the project
4. Communication Between School & Contractor.
Weekly meetings will be set up between school and contractor to explain the week ahead
and any issues which may affect the school in any way.
The Site manager will be available at any time on mobile phone,

in the case of emergency on site the area will be evacuated to a Muster Point which will be
the School field by the trees. The gates to the school could be opened by the appointed key
holder for the day to enable emergency services to enter site, the process will be written
and agreed prior to commencement.
The Construction team and Design team will meet formally with the School every month
dates will be agreed for the entire project period.
The contractor will be Audited by the Considerate contractors Scheme inspector, the results
will be shown to the school
The Site team will attempt to engage the school with the project as there are processes with
the construction process which will be of interest to the school and its curriculum.
This process attempts to raise the level of awareness of the building process and the safety
of Building sites.
Site team will always advise the school of any arrangements of weekend working or
extended working times in the case of testing which needs to be carried out at night
5. Security.
Construction team will ensure that the Site entrance off Broadmoor lane will be kept locked
when not in attendance to prevent unauthorised entry.
This is normal School system

8. Safety Hazards.
Site team will trace all known services, and arrange to have the site surveyed for unknown
services , all service providers will be contacted for up-to-date drawings to check the
possibilities of services,
A permit to dig system will be used , any person breaking the ground will require to have
checked the site services drawings to reduce the risk of service strikes
Overhead services are present these must be identified marked and avoided during the
works
The site entrance roadway is narrow, and has overhanging trees with school staff parking in
the areas as shown on the site proposed layout Appendix 1
Constant supervision as previously described will be employed to reduce the risk of collision.
All staff will be requested to reverse into the spaces provided to reduce the risk of collision
All site vehicles will be able to turn around on site so that no vehicle reverses out on to
Broadmoor Lane.
The site compound area / turning area will be stoned up with clean stone to prevent any
debris entering the school road or the Broadmoor Lane
Contractor will have a wash down point for all vehicles at the site compound entrance.
All contractors have to provide Risk and Method statements prior to starting work , these
are appraised by the site team at least 7 days prior to the start of each operation.
The RAMs are also sent to the CDM for review
The site will be a hard hat site, Boots will be worn to prevent toe injury and metal soles to
prevent puncture injury
High VIZ vests will be worn at all times on site
Appropriate safety wear, Ear protection, Eye protection will also be worn
No noisy operation will be carried out which would be a hazard to the general public or
anyone at the school, arrangements will be made to screen or change method of work if

Digest.
The site and site team will be Audited by the Safety Manager at least every 2 weeks
A report is produced , this is shared with the designer and the school.
9. Significant Design & Construction Hazards.
Designers Risk assessments will identify potential risks to Health and Safety at an early stage,
offering the opportunity to manage out or reduce such risks.
Any changes to the design during the construction phase must be notified to the CDM
coordinator with all information to assess the implications of such changes.
Any changes that do result in significant Hazards and Risks will have New Risk and Method
statements which will need appraising and approval of the CDM Coordinator.
The Construction Phase Plan would be updated accordingly
The works falls into the remit of the Site Waste Management Plan Regs 2008
It is therefore a requirement for the construction team to implement control and manage
the plan on site. the completed plan will be handed over to the school on completion of the
works.
The principal Hazard during construction is falling from height, the use of scaffolding, towers
and cherry pickers minimises the risks,
All staff are trained in safe construction, the site Team are all qualified and hold SMSTS
qualifications and Chartered Builder professional qualifications
Where ever possible risks are removed from the construction process,
The site team hold Tool Box talks to enforce the high standards expected on the project. This
combined with rigorous appraisal of method statements insures safe systems of work
Slips Trips and Falls are also reduced by eliminating all trailing leads by implementing a high
level lead policy,
Managers are qualified with Asbestos awareness, Scaffold appreciation, tower training as a
minimum.
All Managers hold current First Aid certificates.
Every aspect of the process is scrutinised for Risk and every Risk is reduced or removed.
10. Health & Safety File.
The project Team is responsible for promptly providing the CDM coordinator the relevant
information after the construction phase is complete to enable the CDM coordinator to
produce the health and safety File and submit to the school.
The final contents of the O and M manuals are agreed to the satisfaction of the CDM
coordinator .
The site team provide documents that that provide safety information for future
maintenance, use of, and final demolition dismantle in the future.
On completion the O and M Manuals, “as built” drawings; Architectural, Engineers, services,
Mechanical Services , Electrical Services, windows, roofing etc, all providing Installation
description, plant and equipment schedules, operating information, Maintenance
information, emergency procedures, recommended actions and spares, “as built” drawings,
test and commissioning data, along with product warrantees are all issued to the School.
Residual Risk Register showing any items or aspects of the building that require further
ongoing risk management by the school.
