EAST AYRSHIRE COUNCIL
CABINET – 22 APRIL 2015
2015-16 BRIDGE AND CULVERT STRENGTHENING PROGRAMME
Report by the Acting Depute Chief Executive Safer Communities
PURPOSE OF REPORT
1
The purpose of the report is to seek approval of Cabinet for the proposed
schemes listed in the 2015-16 Bridge and Culvert Strengthening Programme
and the re-profiling of the Bridges Capital Investment Programme to create a
three year rolling programme.
BACKGROUND
2
The Council is responsible for 420 bridges, 197 culverts and 150 retaining
walls - 767 structures in total

Cabinet has previously approved a ten year bridges investment programme
amounting to £7.485M from 2013/14 to 2022/23 taking account of priorities
and affordability.
5
A report to Cabinet on 22 April, 2009 described the programmes of bridge
assessments and bridge inspections that are carried out and outlined how the
information is used to prepare prioritised bridge strengthening and
replacement programmes. The Bridge Stock Condition Indicator (BSCI) is
determined from the results of the inspection programme and the scores for
the last 10 years are shown in Table 2 below. The BSCI shows that overall
the structures stock score has dropped in value over the last 10 years
indicating ongoing deterioration in the stock condition. This is despite the
recent increased levels of investment and is indicative of the significant
maintenance backlog that exists and it is only by tackling this backlog that the
stock condition indicator will improve.

The SCOTS Roads Asset Management Plan (RAMP) Performance Indicator
Results for 2013/14 show that within our family group of nine Councils our
BSCI Average score is slightly lower than the Family Group Average score. On
a Scotland-wide comparison, our score is slightly above the Scotland
Average score based on all 32 Scottish Councils.
7
Bridges and culverts are subject to assessment to determine their ability to
carry the 40 tonne assessment loading. In addition all structures are subject
to a programme of regular inspections to determine the condition of the
structure and highlight any defects requiring attention. The inspections
provide the information needed for the preparation of programmes of
remedial action.
8
General Inspections (GI), which are visual inspections only, are carried out on
a two-year cycle. All the structures listed in Table 1 receive a GI and this
includes those structures which are not maintained by the Ayrshire Roads
Alliance eg. Network Rail, BRB Residuary Ltd, other boundary bridges, but
which our roads pass over/under. This is undertaken in the interest of public
safety.
9
Principal Inspections (PI) are a more detailed examination and are carried out
every six years. A full programme of PIs will be undertaken in 2015/16
through the use of in-house staff resources and external sources via the All
Ayrshire Professional Services Framework Agreement.
10
A programme of interim measures has been implemented to manage
structures that have been identified as being weak or requiring upgrading and
include weight restrictions, lane restrictions and / or regular monitoring.
Currently there are 56 bridges that are being monitored on a bi-monthly basis,
3 on a monthly basis and 1 on a weekly basis. This list varies as repairs are
expedited. Such measures will continue to be put in place until improvement
works are brought forward as part of the prioritised programme of Bridge and
Culvert Strengthening. See Appendix 1.
11
The ongoing development of the Road Asset Management Plan (RAMP) is
being facilitated by SCOTS and the Ayrshire Roads Alliance on behalf of East
Ayrshire Council is taking an active role in the project.
BRIDGE AND CULVERT BACKLOG
12
In 2014, the Gross Replacement Cost for the Structures Asset was estimated
at £189M. The bridge assessments, principal inspections and general
inspections that have been carried out to date have identified an estimated
total of over £35.2M of necessary strengthening and upgrading works, as
summarised in Table 3 below.

The bridge and culvert works that are carried out every year are prioritised
using maintenance prioritisation methodologies previously approved by
Cabinet at its meeting on 4 June 2008 and which include a review of the
social and economic impact in the Council area. A simple to use tool to
enable the reporting of long term funding needs for structures is under
development as part of the SCOTS RAMP project. However, an increased
level of funding is required to arrest the rate of deterioration of the asset and
thereafter maintain the asset in a steady state condition. Systems are in place
to manage sub-standard structures as detailed in paragraph 10 above.
THREE YEAR BRIDGE AND CULVERT STRENGTHENING PROGRAMME
14
Table 4 below shows the approved ten year bridges capital budget and a
proposed re-profiling of the budget to accommodate essential works required
to a number of bridges, and the proposal to move to a three year programme.
It should be noted that the approved budget for 2014/15 includes for
£350,000 brought forward from future years to facilitate the construction of
the Dean Road Bridge as approved by Cabinet on the 21 May 2014. Details
of the proposed programmes are included in paragraphs 17 to 23.

A number of issues arose during the 2014/15 financial year that had a major
impact on the approved Capital programme. The issues that arose in 2014/15
are detailed as follows;


A number of projects have cost more than anticipated
A major Capital project (Barskimming Bridge) had to be carried out that
was not known about at the time the 2014/15 programme was approved

A number of essential refurbishments on bridges had to be carried out
but which could not be funded from the limited Bridges Revenue budget
 Some project estimates have been revised upwards
Table 5 details the additional costs arising from these projects;
Table 5 – Additional costs
Scheme
Reason for increase
B744 Little Sorn
Burn Bridge,
Crosshands strengthening
Addition
al cost
£26,000
The original project estimate was £100,000
with final project cost of £126,000. Additional
concrete scour protection and road
resurfacing was required along with additional
import of sandstone masonry as the existing
masonry had been built in cement mortar and
was not suitable for re-use.
Mill Road
The original project estimate was £95,000
£9,000
Footbridge,
with final project cost of £106,000. There
Newmilns were additional structural steelwork repairs
refurbishment
required to the steel truss.
B743 Manse
The original project estimate was £160,000
£97,000
Wall, Sorn
and final project cost was £257,000.
Once the contractor was on site demolishing
the failed sections of wall and exposing other
sections that we originally thought could be
salvaged and repaired, it became obvious
that these sections were of inadequate
construction and would also have to be
replaced.
C3 Barskimming A partial collapse of one of the wingwalls
£500,000
Bridge –
occurred after the 2014/15 capital programme
Wingwall repair was approved. Due to the emergency nature
of the works, it was decided that immediate
works were required. During this time
barriers were located at the edge of the
carriageway and there was an increased
frequency of inspections to ensure the partial
collapse did not compromise public safety.
Following a competitive tender process,
through the Minor Works Framework
Contract, a contractor was appointed to carry
out the proposed repairs.
However, following the initial excavation
works, it was evident that the partially
collapsed 6 metre high wingwall had
completely failed and would require a
significantly more detailed repair. From the
site works, it was evident that the partial
collapse had occurred due to the presence of
a BT underground duct which was acting as a
conduit carrying groundwater to this low point.
As a result significant water pressure built up
behind the wall and forced the collapse to
occur.
There was no evidence when the initial
inspection work was carried out that water
pressure was the most likely cause of this
failure. Therefore, the events that occurred
could not have been reasonably foreseen.
In addition to our works, Scottish Water has
taken the opportunity to re-line the existing
water main in this area.
On site, there has been significantly more
stonework repairs required which only
became evident after the scaffolding was
erected and access made available to allow
for inspection and removal of years of
vegetation growth. Additional works were
also undertaken on another seven metre high
buttress and wingwall which were in poor
condition.
The bridgeworks have been completed.
Scottish Water has completed their re-lining
works (after discussion between Scottish
Water and the Ayrshire Roads Alliance, it was
decided that this work could not be
undertaken concurrently with the bridge
project on health and safety grounds).
The final surfacing is programmed for
Monday 20 April with completion later that
week.
The projected final estimate for these works is
£500,000.
Cabinet is asked to note that due to the
emergency nature of this project these
essential works needed to proceed
immediately in order not to compromise the
safety to the travelling public, and to restrict
the road closure to as short a delay as
possible.
The works were undertaken through the
Minor Works Framework Contract in order to
achieve best value for East Ayrshire Council.
Should similar emergency type works take
place in the future then these will be reported
to Cabinet immediately.

The consequence of the above programme issues is that a number of the
Capital projects approved in 2014/15 have not progressed to site stage, albeit
some design work has begun on others. It is proposed to complete these
works in 2015/16.
17
In order to improve the condition of the bridge stock and complete previously
approved projects, it is proposed to accelerate funding from future years to
create a three year programme. The general detail is stated in Table 4 and
represents a significant increase in the proposed funding.
18
The programme of works for 2015/16 is detailed in Table 6 below and
paragraphs 19 to 22 and includes an update on the progress of previously
approved projects along with revised cost estimates, plus a number of new
projects. The proposed programmes for 2016/17 and 2017/18 are included in
Appendix 2. It is still proposed to provide Cabinet annually with a progress
report on this programme.

Bridge Strengthening and Replacement (£800,000) – In 2015/16 it is
proposed to undertake the bridge strengthening and replacement projects
previously approved in 2014/15 but not yet concluded along with one further
bridge replacement on the A735 near Kilmaurs plus some feasibility and
investigative works to facilitate future schemes.
 C51 Dykefield Bridge, Mauchline replacement (£350,000) - Dykefield
Bridge suffered extensive damage during the July 2012 floods,
necessitating its closure. A design has been prepared which improves the
road alignment/width over the bridge and tender documentation is
currently being prepared. Land acquisition has been problematic and is
still to be finalised. Once land acquisition is concluded the project will
progress towards the tender and construction phases.
 U26 West Clerkland Bridge, Stewarton replacement (£205,000) –West
Clerkland Bridge was closed in the interest of public safety in July 2012
following deterioration in its condition. A design has been prepared which
improves the road alignment/width over the bridge and tender
documentation is currently being prepared. Land acquisition has been
problematic and is still ongoing. Once land acquisition is concluded the
project will progress towards the tender and construction phases.
 B730 Littlemill Bridge, Rankinston replacement (£10,000) - This bridge
fails its 40 tonne load assessment and is currently monitored on a bimonthly basis. A replacement scheme will be developed and land
negotiations undertaken during the coming year with a view to the
replacement being undertaken in future years.
 A71 Mathews Burn Culvert, Darvel (section below West Donnington
Street) replacement (£10,000) - This culvert is 105m long and runs from
West Donnington Street to A71 West Main Street. The section below the
A71 was replaced in 2013 and the remaining 88m length below Burn Road
footway and West Donnington Street fails its 40 Tonne load assessment.
This section is currently monitored on a bi-monthly basis. It is proposed to
develop a replacement scheme and undertake land negotiations during
the coming year for the 15m section below West Donnington Street.
Subject to the project being sufficiently developed and land acquisition
concluded to allow the works to proceed in this financial year, it is
proposed that further funding is accelerated from future years. The
remaining 63m length of culvert below Burn Road footway is considered
lower risk with respect to vehicle loading and will require to be funded from
future years. Bollards have been installed to deter accidental vehicle
loading of the footway.

U64 Gardrum Mill Culvert Bridge, Fenwick – replacement (£45,000) –
The existing masonry arch fails its 40 Tonne load assessment and is in
very poor condition. It is proposed to replace the bridge with precast
concrete box culvert units. The design is complete and it is anticipated that
tenders will be invited in April 2015.
 Isles Burn Culvert, Newmilns - strengthening and scour protection
(Mill Rd Section) (£45,000) – This culvert is 550m long and has various
public roads and private roads/land overlying it. Various sections of the
culvert fail their 40 Tonne load assessment and the overall condition of the
culvert is poor. The section below Mill Road footway fails its 40 Tonne
load assessment and it is proposed to replace this section along with
repairs to adjacent areas of culvert invert which are badly scoured. Further
repairs to the culvert will require to be funded from future years.
20

A735 Brackenburn Bridge, near Kilmaurs – replacement (£70,000) –
The existing 1.2m span masonry arch is in poor condition and it is
proposed to replace it with precast concrete box culvert units. This is a
boundary structure with North Ayrshire and they have agreed to part
contribute £70,000 to the estimated £140,000 replacement cost).

Investigative works – (£50,000) – Specialist ground investigation work
will be undertaken at a number of proposed bridge replacement locations
to help facilitate foundation design and the development of the schemes.
Specialist paint surveys will also be undertaken at various steel bridges to
assess the condition of the existing paint system and provide advice on an
appropriate maintenance specification for work in future years.

Feasibility works – (£15,000) – Feasibility work on future schemes to
determine the extent of land acquisition will be developed.
Upgrading Identified from Inspections – (£300,000)
Structures are assigned a Maintenance Prioritisation Ranking (MPR) with
values ranging from 1 to 4, with 1 indicating acceptable condition and 4
indicating the condition is such that urgent remedial action is required. The
ongoing inspection programmes have identified that there are 69 structures
with an MPR4 ranking. See Appendix 3 for the list of structures. The repairs
to some of these structures will be funded via the Bridges Revenue budget.
However, a number of the structures require extensive refurbishment and it is
proposed to allocate £300,000 to enable a number of essential projects to be
progressed, and therefore improve the general condition of the asset.
Structures in this category, where it is not possible to strengthen within the
existing budget, will be monitored regularly if deemed appropriate. If
significant deterioration occurs before remedial action can be implemented,
consideration will be given to closure of the bridge or implementation of a
weight restriction. Nevertheless, a review will be carried out involving further
inspections and the preparation of cost estimates of those structures with an
MPR4 ranking, as detailed in Appendix 3, in order to inform any future review
of the Council's capital programme.
21
Bridge Parapet Upgrades (£285,000) – A number of bridges have masonry
parapets and other walls which are in poor condition and/or have sustained
vehicle impact damage. As previously approved in 2014/15 it is proposed to
carry out works at the following location this financial year. Other schemes on
the programme will be brought forward if this scheme suffers any delay.
 C125 Spout Linn Bridge, Waterside – (£35,000) Replacement of one
masonry parapet which has suffered vehicle damage with a new upgraded
parapet on a section of rebuilt arch barrel along with other general
masonry repairs.
 A735 Victoria Bridge, Kilmarnock – (£250,000) Replacement of the
existing substandard steel vehicle parapets on the approach retaining
walls, 170m length, with new compliant vehicle/pedestrian steel parapets
on a new reinforced concrete upstand cast onto the existing concrete
retaining wall stem at all four approaches to the bridge. It is also proposed
to grit blast and paint the main support beams of the bridge.
22
Rail Incursions (£15,000) – Safety fencing has already been installed on
three of the four approaches to the C23 Rigg Road Rail Bridge at Cumnock in
order to mitigate the risk of the accidental incursion of vehicles onto the
railway line. It is proposed to install safety fence mitigation measures on the
last corner of this site. This will complete the Council’s last high risk site
which are those sites with a risk ranking score higher than 90. Network Rail
has indicated that they will provide match funding for the mitigation works at
this site.
23
Individual schemes may be adjusted as necessary to take account of the
following:
 variations in price following tendering processes
 changes in the bridge stock condition that can arise throughout the year
and which necessitate urgent action being taken
 the available staff resource, large backlog of bridge maintenance and the
complexity of certain projects which are demanding of staff time.
FINANCIAL IMPLICATIONS
24
The proposed programme of works in 2015-16; 2016-17 and 2017-18 will be
funded from the 10 year Roads and Transportation Capital Investment
Programme.
25
The bridge assessments and inspections carried out to date indicate that
there is a backlog in bridge and culvert strengthening and remedial works of
over £35M. Whilst it is recognised that further funding would allow a fuller
programme to be implemented to address the deterioration and subsequent
maintenance of the relevant assets, interim measures and actions are being
implemented to manage structures that have been identified as being weak or
requiring remedial measures, as detailed previously in Paragraph 10.
LEGAL IMPLICATIONS
26
Roads (Scotland) Act 1984, Part 1, Section 1, requires a local roads authority
to manage and maintain all such roads in their areas as are for the time being
entered in a “list of public roads”. This duty includes the proper maintenance
of all structures carrying or supporting the road.
27
If the structures asset continues to deteriorate the exposure to the Council
from public liability claims may increase.
HUMAN RESOURCE IMPLICATIONS
28
Delivering an increased capital works programme has staffing implications. In
particular structures schemes may require a design input, which may not be
met from existing in-house resources. Framework contracts are in place
which could be used to meet peak demands.
However these external
resources still require to be managed effectively by in-house staff.
COMMUNITY PLAN / POLICY IMPLICATIONS
29
Providing a well maintained road network is consistent with and complements
the Safer Communities and Economy and Skills themes of the Community
Plan 2015-30.
30
If the condition of the structure asset deteriorates this will have implications in
meeting the above aims, for example introducing further weight restrictions to
bridges on the network will impede the movement of people and goods
across the council area.
31
This report meets the needs of the Community Planning partners throughout
East Ayrshire through improving community safety by improving the condition
of the bridge stock. In addition, the developing work through the Community
Led Action Plans also focuses on improvements to the road infrastructure.
EQUALITIES IMPLICATIONS
32
The projects contained within the programmes will be designed to ensure that
they are fully accessible for all, in consultation with the Disability Awareness
Advisor where appropriate.
RISK MANAGEMENT IMPLICATIONS
33
Any delay in the delivery of the 10 year programme will expose the Council to
potential risks with regard to the deteriorating condition of the bridge stock
which could result in structure failure and reduced level of service and
accessibility issues for the travelling public.
34
Interim measures and actions are being implemented to manage structures
that have been identified through the bridge assessment and principal and
general inspection programmes as being weak or requiring remedial
measures. Such measures include introducing weight restrictions, lane
restrictions, monitoring or closing bridges to vehicles/pedestrians.
RECOMMENDATIONS
35
It is recommended that Cabinet:
(i)
(ii)
(iii)
(iv)
(v)
approves the 2015-16 Bridge and Culvert Strengthening Programme of
works, as set out in paragraphs 19 to 22 above;
approves the re-profiling of the Bridges Capital Investment Programme
as detailed in Table 4 to create a three year rolling programme and
agrees the proposed programme for 2016-17 and 2017-18 as set out in
Appendix 2;
notes the works undertaken at Barskimming Bridge as described in
Table 5;
approves that further inspections and cost estimates are prepared for
those structures listed in Appendix 3, in order that this work will inform
any future review of the Council’s Capital Programme;
otherwise notes the contents of this report, in particular, the estimated
cost of the backlog in bridge and culvert strengthening and remedial
works of over £35M and that interim measures and actions are in place
to manage those structures identified as being weak.
