Documents Available for Use in Ireland 1.1 The UK DMRB, Standards are designated by the letters BD, BE, HD, SH or TD and Advice Notes by the letters BA, HA and TA. 1.2 The Standards and Advice Notes of Volumes 1 to 9 of the UK DMRB, as listed in Tables 1 to 9, are applicable in Ireland as amended by the NRA Addendum to each document. All references to the UK DMRB Standards and Advice Notes shall be read as references to the documents as implemented in accordance with the relevant NRA Addendum. The Standards and Advice Notes of Volume 0 and Volumes 10 to 15 of the UK DMRB are not implemented for use in Ireland although some elements may be cross referenced by the NRA Environmental Assessment and Construction Guidelines and by the NRA Project Appraisal Guidelines. 1.3 NRA Standards or other documents that are indicated by * replace equivalent UK DMRB documents. 1.4 UK DMRB Standards and Advice Notes indicated in italics are not formally implemented by the NRA but should be considered as 'background reading' indicating good practice for the activity, or materials, under consideration. Users of these documents must make due allowance for any differences from UK circumstances. Some UK DMRB Standards and Advice Notes are specifically excluded from the NRA DMRB. These are considered as conflicting with current practice in Ireland (or be of no relevance) and are listed in the Tables 1a to 9a. They should, accordingly, not be referred to. In some cases the NRA DMRB continues to reference parts of the UK DMRB that have been superseded or withdrawn from the UK DMRB. The relevant UK DMRB document date of these parts is highlighted by the use of an 'antique text' style

2. ALPHA-NUMERIC INDEX
This Index lists, in alpha-numeric order, the documents in the DMRB as implemented in Ireland, together with their references and date of issue. All information is current at January 2009.
Series The following series of Standards and Advice Notes are listed: BA BD BE HA HD TA TD Advice Notes Bridges and Structures Standards Bridges and Structures Technical Memorandum - Bridges Advice Notes Roads Standards Roads Advice Notes Traffic Engineering and Control Standards Traffic Engineering and Control NRA Introductions to Volumes
Notes: 1. This index lists documents relating to the DMRB which have been adopted for use in Ireland. With the exception of those Standards and Advice Notes which are for background reading only, DMRB documents which have not been implemented in Ireland are not listed. Standards and Advice Notes which have been prepared by the National Roads Authority to replace the equivalent UK DMRB documents are prefixed with NRA and shown with an asterisk (for example, NRA BD 2/01*). They are included in the relevant parts of the index. All Standards and Advice Notes of the UK DMRB which have been adopted for use in Ireland have a corresponding NRA Addendum which describes particular requirements of the National Roads Authority. The date of the current NRA Addendum is given for each document. The DMRB Part number is given for each document to assist in locating it within the manual. These numbers are in the form Volume.Section.Part (e.g. 1.3.5). However, documents issued before the compilation of the UK DMRB in 1992 (and some later ones) do not have Part numbers; they are identified by Volume and Section and are generally placed at the end of the relevant Section. Also, in some instances several documents have the same Part number. The documents listed in Tables 1 and 3 have been published since the issue of the previous edition of the NRA Alpha-Numeric Index. Lists of the documents withdrawn since the previous edition of the NRA Alpha-Numeric Index are included in Tables 2 and 4. These documents should be archived as appropriate.

NRA INTRODUCTIONS TO VOLUMES Note: 1 These Introductions are no longer updated. For the latest lists of Standards and Advice Notes, refer to the Alpha-Numeric Chapters 1 and 2 of this document.
3.1 All technical enquiries or comments on this document or any of the documents listed as forming part of the NRA DMRB should be sent in writing to: Head of Engineering Operations National Roads Authority St Martins House Waterloo Road Dublin 4
........................................................................ E OCONNOR Head of Engineering Operations
A1 WHAT IS A DEPARTURE FROM DMRB?
There are a number of mandatory requirements within the Standards and Addenda of the National Roads Authority (NRA) Design Manual for Roads and Bridges (DMRB), which must be adopted by the Design Organisation. If the Design Organisation wishes to deviate from these mandatory requirements, they must obtain the formal approval of the NRA by making an application in writing together with details of their alternative proposal(s). Such an alternative is referred to as a Departure. Examples of Road Geometry Departures are clearly defined in TD9 Paragraphs 1.15 to 1.31. This standard defines a three-tier hierarchy (based on Design Speed) as follows: Tier 1 = Desirable Minimum Standard Tier 2 = Relaxations Tier 3 = Departures When to consider a Departure: Situations of exceptional difficulty, which cannot be overcome by Relaxations, may be able to be resolved by the adoption of Departures, the third tier of the hierarchy. A proposal to adopt Departures from Standard must be submitted to the NRA to enable full appraisal to be made, with verification that safety is not significantly reduced. This appraisal and NRA approval (to the proposals) must be obtained before incorporation into a design layout. Technical requirements of standards are distinguished by use of a text box. These are the sections with which the Design Organisation must comply or must have agreed a suitable Departure from Standard with the NRA.
A2 WHAT IS NOT A DEPARTURE FROM DMRB?
Any variation that is not considered as constituting a Departure especially: Suggestions/Recommendations within DMRB e.g. some Annexes contain recommendations or suggestions, for example TD27/07 Annex A contains a suggested range of cross-sections for use on rural non-national roads. Anything contained within Advice Notes adopted as best practice advice or as background information only. (Generally to be read in conjunction with a related standard.) Relaxations these need to be recorded in the Departures Report, but a formal application does not need to be completed. Anything outside of the NRA DMRB (Volumes 1 to 9), such as: Amendments to Employers Requirements UK DMRB Standards not Applicable in Ireland
A3 HOW DO I SUBMIT A DEPARTURE APPLICATION?
Departures Reports shall be prepared consisting of three separate volumes: Volume 1 All DMRB applications excluding Structures. Volume 2 All DMRB departures in relation to Structures. Volume 3 All applications in relation to Specification. The Departures shall be submitted as follows: Cover letter with 1 full set of Departures applications (3 Volumes) accompanied by a CD or email of the application forms in Word format to the NRA Project Manager (Engineering Standards). Cover letter (only) detailing Departures applications to the NRA Senior Project Manager (Engineering Standards). Cover letter with 1 full set of Departures applications (3 Volumes) to the Project Engineer of the Regional Design Office (RDO) or Local Authority (LA) where Consultants are employed. (For Design & Build Schemes the Project Engineer shall mean the Employers Contact Person as nominated in the Instruction to Tenderers, for PPP schemes the Project Engineer shall mean the Authoritys Representative). Cover letter with 1 Structures Volume directly to NRA Structures Section. During the Design & Build Tender Process an additional set of Departure Reports (3 volumes) shall be prepared by the Tenderers and forwarded to the Consultants Contact Person as nominated in the Instructions to Tenderers. A reply outlining the decision of the NRA on the Departures will be issued to the Project Engineer/Employers Nominated Person/Authoritys Representative as appropriate. The Project Engineer/Employers Nominated Person/Authoritys Representative should forward the decision of the NRA to the applicant as appropriate. Copies of the decision will also be issued to the NRA Project Manager (Engineering Standards), the RDO/Local Authority, the NRA Engineering Inspector and NRA Structures Section/NRA Specification Section as appropriate. Contact details in NRA for submission of Departure Reports are as follows: NRA Project Manager (Engineering Standards) National Roads Authority St. Martins House Waterloo Road Dublin 4 E-Mail: dmrbdeps@nra.ie
NRA Senior Project Manager (Engineering Standards) National Roads Authority St. Martins House Waterloo Road Dublin 4
A4 WHAT SHOULD AN APPLICATION CONTAIN?
The NRA Project Reference Number. A short description of the scheme, including details of the type of contract, the stage the scheme is at and other background information. The outcome of any Safety Audits and Statutory Processes should also be detailed if applicable. A Cover Sheet for Departure Reports is included in Appendix 1 which should be used to provide the required information. A Departure Application Form (as contained in Appendix 2 and can be downloaded at http://www.nra.ie/Publications/DownloadableDocumentation/NRAForms/file,3522,en.doc) for each individual application. The application form should contain sufficient detail to enable a recommendation to be made on the application. It is particularly important that the Justification section is fully completed, and a detailed reason given why the departure is being sought. If alternative designs have been considered in order to avoid the departure, these should be outlined. Proposed compensatory measures should also be outlined where applicable. A detailed drawing for each departure showing plan and long section (in all cases), so geometric details can be ascertained. This drawing should also show (with dotted lines or different colours) how the area of the scheme would look if the correct standards were applied. The drawing should clearly show the scale used. This enables the reviewer to see the difference between standard and substandard design and to understand more clearly the justification for the departure. Drawing(s) of the entire scheme (at min scale of 1:10000), so the reviewer can see how the departure fits in with the overall scheme. Contact details for the Project Engineer, Clients Engineer and/or who to contact for further information. A CD or email containing the application form(s) in Word format to facilitate input into the database. If a number of applications are being submitted at the same time, then these should take the form of a Departures Report. The report should be bound and include the necessary drawings within the bound report. A3 drawings are preferable but this will depend on the amount of information contained on the drawing. If A1 drawings are required then these should be folded and bound into the report in plastic sleeves. If an application does not contain sufficient information for assessment, then the departure will be returned to the applicant, and a subsequent time-frame for assessment cannot be guaranteed. A Departure Application Checklist has been provided in Appendix 3 which should be completed and returned with the Departures Report.
A5 DEPARTURE DECISION PROCESS
The Departure Application/Report is submitted to the NRA Project Manager (Engineering Standards). (Note this applies to all applications). All departures are input into a database and cross-referenced against previous applications. The relevant NRA section will make a recommendation on each individual application: o All structures departures are forwarded to NRA Structures Section for comment. o All geometric and specification applications are assessed by the Standards section. All comments/recommendations are recorded in the database and approval and refusal numbers are assigned as appropriate. A Summary sheet is prepared with the recommendations on all departures. Approvals are signed by the NRA Head of Engineering. The decision of the NRA is notified to the applicant by the Project Manager (Standards). Time Frame: Applicants should allow a minimum of 3 weeks from receipt of applications by the NRA to notification of decision. (This will take longer for larger schemes with a large number of applications especially during the D&B/PPP Tender process where there may be multiple sets of departure requests). The time taken to assess departures will depend on the number of applications; the quality of information submitted and scheme priority. Accordingly, applications should be submitted as early as possible so as to avoid delays.
January 2009 A/3
If a scheme with a large number of applications is to be submitted, then advance notice should be given to the NRA Project Manager (Engineering Standards) in order that the applications can be dealt with as swiftly as possible. In the case of Design & Build or PPP schemes, information contained in the Contract Documents regarding the submission of departures should be forwarded to the NRA Project Manager (Engineering Standards) for information (this applies in particular to the timetable for submission of departures during the tendering process).
A6 ELECTRONICALLY SUBMITTED DEPARTURES
Electronically submitted departures (to dmrbdeps@nra.ie) will be accepted for processing but this processing cannot be completed until the NRA Project Manager (Engineering Standards) receives a hard copy. In all instances the hard copy will be taken as the overriding document, as this will ultimately hold any relevant signatures. In order to speed up the processing of applications, particularly for large projects, the application forms should be submitted in Word format. This will facilitate quick cut and paste input into the database (Note: PDF format does not provide the same opportunity.). Should the departure report contain a small number of applications then these may be submitted via e-mail. For larger reports the application forms should be submitted on CD at the same time as the paper copy.
A7 DEPARTURES WHEN SHOULD THEY BE SUBMITTED?
NRA PROJECT MANAGEMENT GUIDELINES (2000) PHASE 4 PRELIMINARY DESIGN & LAND ACQUISITION MAPPING. Applications for Departures from Standards during the Preliminary Design Stage must be submitted for assessment prior to incorporation into the design, and well in advance of the finalisation of the landtake line for Compulsory Purchase Order. The Senior Engineer responsible for the design shall complete the Departure Application form in full. In the case of a Consultant designed project the Senior Engineer shall submit the Departures Report to the Project Engineer within the RDO/LA for formal submission to NRA. The official decision of the NRA will be issued to the Project Engineer (RDO/LA) who should forward it to the Senior Engineer. In the case of D&B/PPP projects, any Departures from Standards relating to the Specimen Design shall be submitted well in advance of the CPO process for the scheme. Submission of the Specimen Design at this early stage will help to facilitate speedy assessment of Departures during the Tender phase of the scheme. NRA PROJECT MANAGEMENT GUIDELINES (2000) PHASE 5 - PREPARATION OF CONTRACT DOCUMENTS. When the designer proposes to specify Employers Requirements that require the approval of a departure from the DMRB or an approval in relation to the NRA Specification then these should be applied for and obtained before incorporation into the Contract Documents. The Tendering Timetable should be forwarded to the NRA Project Manager (Engineering Standards) for information as soon as it is available. NRA PROJECT MANAGEMENT GUIDELINES (2000) PHASE 5 TENDERING PROCESS. For D&B/PPP schemes, the Designer for the Tenderer should prepare the required copies of the application forms and submit them, together with the accompanying information (as detailed in paragraph A3) on or before the date specified in the Instructions to Tenderers. Submitting applications on or before the date specified allows processing and issue of a reply 2 weeks before the end of the tender process - a reply cannot be guaranteed for applications submitted after the date specified in the Instructions.
January 2009 A/4
The Consultants Nominated Person, upon receipt of the Tenderers applications, will prepare a summary table of all the applications and add the design teams comments before forwarding the comments to the NRA Project Manager (Engineering Standards). This work must be completed in a minimum of 7 working days. The design teams comments will be taken into account in assessing the departures for official recommendation. The official decision of the NRA will be issued to the Employers Nominated Person who then informs the Tenderers of the decision. NRA PROJECT MANAGEMENT GUIDELINES (2000) PHASE 6 - DEPARTURES DURING CONSTRUCTION. Departures will be processed as quickly as possible during the construction phase; however, as in all cases, a minimum of 3 weeks should be allowed for processing of applications. During Construction the Contractors Designer submits the Departures Report to the Clients Representative, who comments on the application(s) and forwards the Report to the NRA Project Manager (Engineering Standards). The reply will be issued to the Clients Representative who should forward it to the Contractor.
DEPARTURES DURING CONSTRUCTION. Departures will be processed as quickly as possible during the construction phase; however it is not possible to confirm any turn-around period. In this case the Contractors Designer submits the 4 copies of the applications to the Clients Representative, who comments on the application and forwards it for processing as above. The reply will be issued to the Clients Representative who should forward it to the contractor.
