SECTION 18
CONCEPT AND PROPOSAL SKETCHES
RTA Structural Drafting Proposal Sketches and Detailing Manual
18 CONCEPT AND PROPOSAL SKETCHES 18.1 GENERAL
A Bridge Design Proposal is comprised of RTA Form No 62 “Bridge Design Proposal” and a Proposal Sketch.
A Proposal Sketch is a plan or set of plans prepared to depict what is considered to be the most appropriate type of structure for the site under consideration and shows the location, details of the site, the type of construction and the major dimensions of the proposed bridge.
18.2 CONCEPT SKETCHES
A Concept Sketch is a design development sketch used to assist both design staff and the client with the choice of the most appropriate type of structure for the site under consideration. Concept Sketch development is often used to trial multiple options or alternatives for the proposed bridge site in order that client input and feedback may be obtained prior to the selection of the preferred option. Options may include various horizontal and vertical alignments as well as superstructure types, bridge lengths, bridge widths and locations. The information to be shown on Concept Sketches is similar to that shown for Proposal Sketches as outlined below, however, in most instances, the information shown is less refined than that for a Proposal Sketch.
A typical Concept Sketch is shown in Figures 18.2.1A and 18.2.1B.
Concept sketches submitted by the tenderer on design and construct and similar contracts should be of a similar standard.
18.3 REGISTRATION AND NUMBERING
When prepared by the Authority’s Bridge Engineering Section, all Concept Sketches and Proposal Sketches, shall be registered as sketches and numbered in accordance with Section 3 of this Manual.
18.4 INFORMATION TO BE SHOWN ON PROPOSAL SKETCHES The following information shall be shown on Proposal Sketches. Plan View Elevation Typical Cross Section Locality Plan Site Plan Vertical Alignment Diagram (if applicable) Horizontal Alignment Diagram (if applicable) General Notes Title Block
The information to be shown (where relevant) is as stated below. Where the information to be shown is not available at the time that the Proposal Sketch is prepared, it shall be requested from the relevant Client’s office.

18.5 DRAWING CONVENTIONS
The preferred scales for use on Proposal Sketches are 1:1, 1:2, 1:2.5 and 1:5 or their decimal multiples represented in the format shown in Section 7 of this Manual. Views shall be drawn to a definable scale and shall be labelled appropriately. The Plan and Elevation shall be drawn to the same scale with the Elevation being projected from and directly above the Plan. Chainages shall increase from left to right in most applications, the only exception being where the Proposal is for a bridge widening. In the case of a bridge widening, the Proposal shall be prepared in accordance with Section 30 of this Manual. Abutments shall be labelled “Abutment A” (for the left hand end of the bridge – the end with the lowest chainage), and “Abutment B” (for the right hand end of the bridge – the end with the highest chainage ), the only exception being where the Proposal is for a bridge widening. In the case of a bridge widening, abutments shall be labelled in accordance with Section 30 of this Manual.
OTB005 Issue 1 – Revision 1 (16 May 2008) Page 4 of 6
RTA Structural Drafting Proposal Sketches and Detailing Manual
Spans and Piers shall be numbered ie “Span 1”, “Pier 1” as appropriate. Chainages and Reduced Levels shall be given to the nearest 0.001m. Contract levels shall be given to the nearest 0.1m. Existing surface levels shall be given to the nearest 0.1m
Arrows that denote the grade of the deck, crossfall or superelevation shall always point in a downward direction (from the higher end/side to the lower end/side)
18.6 ORIENTATION 18.6.1 LOCALITY PLAN
The Locality Plan shall be orientated with the cardinal directions of the compass square to the borders of the sheet, with North being at the top.
18.6.2 PLAN AND SITE PLAN
The Plan and Site Plan shall be orientated in the same direction for convenient reference. 18.7 ISSUE OF PRELIMINARY SKETCHES
Where prepared by the RTA’s Bridge Engineering Section, any Concept or Proposal Sketch that has not been formally approved and is issued to any party for the purpose of checking, comment or review, shall be marked to clearly show the stage of development of the sketch. This shall be shown as percentage complete and it shall be placed beside the words Issue Status in the title block, a typical description being 75% COMPLETE. Sketches that are in the development stage shall have a numerical character shown in the Issue box in the bottom right hand corner of the title block. The first issue of the sketch for the purpose of checking shall be denoted Issue 0. When Issue 0 is amended it shall become Issue 1 and this number shall be updated with each successive issue of the sketch.
18.8 SUBMISSION OF PROPOSAL SKETCHES FOR APPROVAL BY CLIENT
Proposal Sketches that are to be submitted to the client for approval shall have Issue A recorded in the appropriate position in the title block and the words “FOR APPROVAL” entered into the space provided beside the words Issue Status in the title block.
18.9 AMENDMENTS TO APPROVED PROPOSALS
Approved Proposal Sketches may only be amended in accordance with Clause 15.4 of this Manual. Where significant changes to an approved Proposal Sketch are required, eg span lengths, structure width, superstructure type etc, a new Proposal Sketch shall be prepared with the new Proposal Sketch containing a reference to the superseded Proposal Sketch.
18.10 PREPARATION OF SKETCHES FOR HERITAGE ISSUE CONSIDERATION Where sketches are prepared for rehabilitation work on existing bridges that are to be submitted to the client and the Heritage Office for consideration, the structure shall be shown in its existing condition and the convention of showing existing work in “existing” line style (double dashed chain line) is not required.
OTB005 Issue 1 – Revision 1 (16 May 2008) Page 5 of 6
RTA Structural Drafting Proposal Sketches and Detailing Manual
In the case of plans, part plans, elevations, part elevations, sections and part sections, a view of the structure in its existing condition shall be shown directly above (or beside as appropriate) the structure in its proposed condition following the required rehabilitation works so that direct comparison can be readily made. In order to satisfactorily illustrate the proposed changes to the existing structure, only those elements to be replaced need be shown in normal line intensity. Existing elements that will remain shall be shown in lines with reduced intensity or in grey scale. As the sketches do not show strict engineering details, an architectural presentation style may be adopted. Figures 18.10.1 – 18.10.5 show a typical example of a suite of sketches prepared for heritage issue consideration in rehabilitation works.
