DESIGN STAGES
FOR CONSTRUCTION
• Drawings • Drawings
• Schedules • Schedules
• Specifications • Specifications
• Models • Conditions of contract – standard,
specific and special
• Perspectives • Tender documents or negotiation
documentation
• Schedule of quantities – if applicable
– Refer to proforma drawing list on Moodle (medium sized project)
– NZCIC Design documentation guidelines / deliverables ;

– Office records from previous projects
– Experience
What is Documentation
• producing drawings, specifications and other information; ie schedules
• takes about 40 – 50% of the total time spent on each project – refer to fee split table
• Quality management required, not just last minute checking
• Forward planning required to successfully manage projects
Documentation Stages
• Different requirements at different design stages
• Detailed Design documentation is the information from which the project is most
accurately costed
• Detailed Design documentation is what the Building Consent is based on and built from
• Detailed Design stage is where $ are most easily lost within the architect’s fee
Why use work stages?
• To break the work into manageable packages
• To divide the fee across the work required – cash flow advantage
• To allow for client approval as the work proceeds
• To assist with management of the project within the office
Different requirements at each stage
• Pre design
• Concept design
• Preliminary design
• Developed design
• Detailed design – Documentation stage – Working drawings
• Procurement
• Contract administration and observation – project on site
• Defects liability Period

New Zealand Construction Industry Council
• www.nzcic.co.nz/Design.cfm -­‐ Design Documentation Guidelines
• Read preamble, architectural guidelines /deliverables and co-­‐ordination guidelines
• Defines documentation appropriate to each stage
• Split into sections relevant to each consultant type
The following notes are largely drawn from -­‐"Production Drawings -­‐ a code of procedure for
building works" published in London by the Building Project Information Committee 1987.
UNITEC Library ref 692.1 PRO (M)
This is an excellent and still very relevant handbook of practical advice and recommended
reading.
From: 1 Introduction
Drawings show (inter alia) size, shape and relationships.
Drawings cannot be neatly parceled into categories, e.g. roof or wall
Drawing arrangement schemes need to be flexible
From: 2 Coordination of information on drawings
− Responsibilities of architects and other consultants (for information on drawings) needs to
be spelt out in compatible agreements for services made with the Client, e.g. are structural
details for a small job to go on the architect's drawings -­‐ or to be separate on the Structural
Engineer’s drawings?
− Who checks that such details are correctly drawn?
− Coordination of drawing information is a major process
− Layer CAD drawings to assist with co-­‐ordination
From: 3 Drawing arrangement
− For small to medium sized projects of simple construction there might be (say) 30 drawings
in a typical set,
− simple logical sequence combining layouts, details and schedules.
− For a medium-­‐sized project of complicated construction, or a large but simply constructed
project, a set of (say) 100 drawings might be required.
− LAC system – ‘location’ drawings, schedules, ‘assembly’ drawings and
‘component’ drawings.
− For a large project of complicated construction, with (say) >250 drawings in the set
− subdivision of the building(s) into parts, (each with its own set of location,
assembly and component drawings and schedules)
From: 3.4 Types of drawing arrangement
− Group by office of origin ie separating the drawings produced by architects, structural
engineers, services engineers and other specialists (and sometimes giving each group a
distinctive code, such as A, S, M, E).
− Grouping by type of information, at its simplest, separates
− plans/elevations/sections
− schedules
− details,
− Grouping by Location, Assembly and Component – LAC’s
− Grouping by parts of the building, ie (say) foundations, drainage, walls, roof -­‐ Components
− Grouping by contractor is another possibility, (particularly applicable to "Fast Track" and
"Managed” projects, where tenders are often called for separate "packages" of work -­‐ often,
but not always, reflecting a trade breakdown of the work. )
− Grouping by location separates the project into "zones or "blocks on plan
− CIS/fB classification system not used these days

From: 4 Format of the drawings set – sheet size
− Usually A 1 for Location drawings
− A 1 or A3 for Assembly/Component drawings
− A2 is an optional size for small projects. Little drawing information can be put on an A4 page.
Beware of proliferating too many A3 and A4 details into “books" of details. Easy to photo-­copy
but it is very difficult for on-­‐site personnel to see the relationships between the details.
Selection of drawing scales:
− Different scales for different types of information
− 1:100 / 1:200 / 1:500 Site Plans
− 1:1 00 / 1:50 common for Location drgs
− 1:1 0 / 1:20 / 1:5 common for details
− Councils have specific scale requirements for Resource and Building Consent Applications
From: 6 Drawings content
Research in UK highlights inadequate dimensioning and fixing notation as major flaws.
From 6.3 Annotation
− Titles
− Key Notes – on the sheet of details or on a separate sheet? . Notes can cross reference to
spec clauses.
− Do not duplicate information
− What to include?
o What is it? joist
o What is it made of? pinus radiata (better in specification)
o Has it important features? treated (better in specification)
o What size is it? 100 x 50mm
o Specification reference?
Drawing referencing
− NOT "See engineer's drawings" – refer to specific drawing number
− from general to particular (eg. location drawing to details) but also in reverse (back
referencing)
CAD Standards
− To set quality standards
− Standard procedures and philosophies
− Speed and accuracy
− Efficiency, logic and consistency
− Increase productivity and reduce unnecessary down time
− Reduce frustration
− Ease of access – internal and external
− AS 1100.001 – 1992 Technical drawing, AS 1100.301 – 1992 Architectural drawing
