requirements for preparation and delivery of As-Built Records for all national road schemes or any
other road scheme in Ireland for which As-Built Records are required.
1.2 This Standard should be read in conjunction with NRA BD 02, Technical Acceptance of Structures on
Motorways and Other National Roads, when dealing with structures on national road schemes.
1.3 The As-Built Records required by this Standard shall not be construed as exhaustive in all
circumstances. Where necessary, supplemental records shall be compiled on a project by project basis
to ensure effective management and maintenance of the National Road Network.
1.4 This Standard also identifies how the As-Built Records shall be stored and identifies the parties
responsible for preparing, delivering and storing the As-Built Records.
1.5 The requirements set out in this Standard represent a minimum level of technical information to be
provided to the Road Authority as part of the completion of a road scheme development in Ireland.
These requirements in no way replace or change the separate legal requirements for a safety file to be
prepared under the Safety, Health and Welfare at Work (Construction) Regulations 2006 (S.I. No. 504

2. AS-BUILT RECORDS – GENERAL
REQUIREMENTS Introduction
2.1 A standardised approach to the preparation, delivery and storage of As-Built Records is required,
which is intended to be a natural progression from the design and construction processes utilised by
the Employer, Contractor, Designer and Employer’s Representative (as appropriate) throughout the
design and construction of the road scheme. This Chapter 2 sets out general requirements applying to
certain elements of As-Built Records and the As-Built Records as a whole. Particular requirements
are set out in Chapter 3.
General
2.2 For National Roads Authority promoted schemes, all As-Built Records must clearly highlight both the
Scheme Name and the NRA Project Reference Number as they appear on the NRA Project Reporting
System (PRS). The NRA PRS is available on request from the National Roads Authority.
2.3 All As-Built Records, whether interim or final, shall be submitted in hard copy and electronic formats
(electronic form shall be on CD-ROM or DVD-ROM). One complete hard copy of the As-Built
Records and three copies of each CD-ROM or DVD-ROM shall be supplied to the Employer fully
labelled and indexed. One complete copy of each CD-ROM or DVD-ROM shall also be supplied to
the Head of Network Management, National Roads Authority, fully labelled and indexed. The format
for labelling and indexing shall meet the requirements of the Contract, as shall the electronic format of
the data on the CD-ROM or DVD-ROM. In the absence of contractual requirements, the format for
labelling and indexing will be as agreed in writing with the Employer.
2.4 All As-Built Records shall be delivered in digital and hardcopy format. Digital files shall be provided
in native (editable) and PDF (Adobe Systems Portable Document Format, locked to editing) file
formats. Native files shall be provided in a format consistent with the source software used to create
the files.
2.5 All hardcopy As-Built Records prepared using colour elements to communicate pertinent information
shall be reproduced in colour for delivery.
2.6 All As-Built Records shall be clearly marked “As-Built Record” in red.
2.7 All As-Built Records shall meet the requirements of this Standard.
Non-Conformance Reports (NCRs) and As-Built Records
2.8 All issues raised in non-conformance reports (NCRs) shall be addressed in parallel with the production
of As-Built Records. All NCRs raised more than 4 weeks prior to the submission of interim As-Built
Records shall be closed-out by the time the interim As-Built Records are submitted. All NCRs raised
on the scheme shall be closed-out to the satisfaction of the Employer prior to the submission of final
As-Built Records.
As-Built Topographic Surveys
2.9 As-built topographic surveys shall be provided in accordance with the requirements set out in this
Standard to verify the completed works, and shall form the basis for the production of as-built
drawings.
National Roads Authority Volume 0 Section 3
Design Manual for Roads and Bridges Part 2 NRA GD 101/13
March 2013 5
As-Built Documents
2.10 As-built documents shall be provided in accordance with the requirements set out in this Standard.
The as-built documents to be prepared consist of reports, tables and schedules summarising the key
features of the scheme, templates for which have been included in Appendix A and referred to in
Chapter 3.
As-Built Drawings
2.11 As-built drawings shall be provided in accordance with the requirements set out in this Standard.
2.12 The as-built drawings shall include a Location Plan to a suitable scale and an Index of all as-built
drawings contained in the set.
2.13 Apart from Location Plans, or where particular requirements in this Standard differ (see Chapter 3),
the maximum permitted plan scale for all as-built drawings shall be 1:2,500.
2.14 All as-built drawings shall provide location references to the Irish Transverse Mercator (ITM) system
with vertical elevations referencing the ITM Datum. Reference to localised co-ordinate systems or
chainages shall not be permitted.
2.15 Hardcopies of as-built drawings shall be prepared at A1 paper size. Additional hardcopies at reduced
paper sizes may be prepared, if so required in the Contract.
2.16 Digital as-built drawings shall be prepared using CAD type software. Linear plan records (e.g.
carriageway drains, pavements, fencing) shall be represented as three dimensional line strings in a
CAD file format.
2.17 The line strings shall be represented on separate layers for ease of extraction into other systems.
2.18 Each CAD layer shall be assigned a unique name, line type and colour. The table in Appendix B
includes a non-exhaustive list of typical road features and associated CAD characteristics that shall be
used as a minimum in the production of the as-built drawings. At the outset of the preparation of the
as-built drawings, a full list of layers, names, line types and colours shall be prepared (including those
listed in Appendix B as a minimum) and agreed with the Employer. It is this scheme-specific list of
features that shall be used in the production of the as-built drawings.
2.19 All as-built drawings shall be fully consistent with the as-built topographical survey undertaken as part
of the scheme.
Additional As-Built Material
2.20 Additional as-built material shall be provided by the ABR Producer, in accordance with the
requirements set out in this Standard. The additional as-built material required is outlined in Chapter 3,
and is intended to capture all pertinent material required to complete the As-Built Records, including
anything which is not already contained within the documents and drawings sections of this Standard.
Storage of As-Built Records
2.21 The ABR Producer shall store all As-Built Records in good condition for a period of nine years from
the handover of the scheme.

3. AS-BUILT RECORDS – PARTICULAR
REQUIREMENTS
General
3.1 This Chapter sets out the particular requirements of the As-Built Records.
3.2 Where the road scheme involves alterations, or additions, to roads or other features outside the extent
of the site, the As-Built Records pertaining to such shall be in a separate file or separately identified so
that the relevant information can be passed to the "'owner" of the road or feature (this shall also
include Accommodation Works undertaken other than on private domestic properties). In such cases,
it shall not be acceptable to cross-refer to other As-Built Records and the file, or part, shall be a stand-
alone document. This shall be particularly so for Structures where information shall be provided for
all structures in accordance with NRA BD 2.
3.3 This Standard applies to all road scheme infrastructure such as bridges, culverts of diameter greater
than 2.0m, retaining walls greater than 1.5m retained height, sign gantries extending over the
trafficable area (including hard shoulder), environmental noise barriers, high mast lighting columns,
and the like.
As-Built Topographic Surveys
3.4 As-built topographical surveys shall be provided, at 1:500 scale, of all works undertaken on the
scheme which are accessible for survey on completion of the works, including as a minimum the full
extent of the site, any tie-in or modification works to adjacent schemes, and all areas outside the site
where work has been undertaken as part of the scheme.
3.5 As-built topographic surveys shall include all features required to be shown as As-Built Records under
the scope of this standard, and outlined in section 1.8 above. Specific feature information shall be
annotated and layered as per section 2.18 of this Standard.
3.6 The maximum error between permanent survey control stations shall not exceed 1 in 40,000. For
distances between adjacent permanent survey control stations of less than 300 metres, the maximum
error should not be greater than ±5mm.
3.7 The height difference between any two points used as permanent ground markers or permanent bench
marks shall not be in error by more than ±(10k) mm, where k is the distance in kilometres between the
two points being considered, or ±5mm, whichever is the greater.
3.8 The accuracy of features shall be defined in terms of tolerance values and recorded points. The
tolerance values stated in Table 1 in section 3.10, and in Table 2 in section 3.15, are root mean square
(r.m.s.) values and the following conditions shall be satisfied:
i) At least 67% of all readings must be correct to or better than the root mean square
error (r.m.s.e.)
ii) At least 90% of all readings must be correct to or better than 1.65 times the r.m.s.e
iii) All readings must be correct to or better than 3 times the r.m.s.e
3.9 All readings not complying with the 3 conditions in section 3.8, including consequential errors, shall
be corrected.

represented on the plans. Ground survey spot levels on hard surfaces shall be correct to ±10mm
r.m.s.e. and elsewhere to ±50mm r.m.s.e. when checked against the nearest survey control point.
3.12 Contours shall be shown at vertical intervals of 1 metre with major contours every 5 metres. At least
90% of all contours shall be correct to within one half of the specified contour interval. Any contour
which can be brought within this vertical tolerance by moving its plotted position in any direction by
an amount equal to 1/10th of the horizontal distance between contours, or 0.5mm at plan scale,
whichever is the greater, shall be considered as correct. Contours that cannot be surveyed to the
specified accuracy without extensive clearing shall be;
(a) surveyed approximately and annotated accordingly, or
(b) cleared to enable a survey to the specified accuracy to be undertaken
3.13 In flat areas where the horizontal distance between contours generally exceeds 50mm at plan scale,
supplementary spot levels shall be surveyed at intervals not exceeding 50mm at plan scale, parallel to
the contours.
3.14 The ground surface over the required area shall be simulated by 3-dimensional strings of co-ordinated
information along characteristic lines in the terrain, together with point features. Features recorded
shall be those specified.
3.15 The spacing of points along 3-dimensional feature strings shall be such that the vertical and horizontal
distances between the straight line joining adjacent points on the string and any point along the actual
ground feature shall not exceed the r.m.s tolerances specified in Table 2 below.
