2. Whoever the user is and the users of a set of
drawings will be many. The Information
provided in the drawings should be:
REQUIREMENTS OF WORKING DRAWING
 an accurate record of the designer’s
intentions
 clearly expressed and easily understood
 Comprehensive and sufficiently detailed for
its purpose.
 easily retrievable from the mass of other
information with which, inevitably, it will
be combined.

3. THE USE OF WORKING DRAWING
 A basis for tendering (‘bidding’ )
 A contractual commitment
 A source for the preparation of other
documents
 A statement of intent for the purpose of
obtaining statutory consents
 A framework for establishing nominated
subcontractors or suppliers
 shopping list for the ordering of materials

4.  A construction manual
 A model for developing the construction
programme
 A supervising document
 A record of variations from the contract
 A base document for measurement of the
completed works and preparation of the
final accounts
 A base document for defects liability
inspection
 A record of the completed structure
 A source of feedback.

5. The Architects functional stages in any
project are classified into three and
these are:
 Feasibility stage
 Pre-construction stage
 Construction stage
ARCHITECTS FUNCTIONAL STAGES
IN PROJECTS.

6. FEASIBILITY STAGE
During this stage the Architect is
involved in the following:
 Appraisal
 Strategic Briefing

7. APPRAISAL
 Identification of client’s requirements and of
possible constraints on development.
Preparation of studies to enable the client to
decide whether to proceed and to select the

organisational structure and range of
consultants and others to be engaged for the
project.

8. This stage constitute the bulk of the works
that an Architect does in the project
development. It involve the following:
 Outline Proposals
 Detailed Proposals
 Final Proposals
 Production Information
 Tender documentation
 Tender Action
PRE-CONSTRUCTION STAGE

9.  Commence development of Strategic
Brief into full Project Brief.
 Preparation of Outline Proposals
and estimate of cost.
 Review of procurement route.
OUTLINE PROPOSALS
DETAILED PROPOSALS
 Complete development of the Project
Brief.
 Preparation of Detailed Proposals.
 Application for full Development
Control approval.

10. FINAL PROPOSALS
 Preparation of Final Proposals for the
project sufficient for coordination of all
components and elements of the project.
PRODUCTION INFORMATION
 Preparation of production information in
sufficient detail to enable a tender or
tenders to be obtained.
 Application for statutory approvals.
 Preparation of further production
information required under the building
contract

11. TENDER DOCUMENTATION
 Preparation and collation of tender
documentation in sufficient detail to

project.
TENDER ACTION
 Identification and evaluation of potential
contractors and/or specialists for the
construction of the project.
 Obtaining and appraising tenders and
submission of recommendations to the
client.

12. CONSTRUCTION STAGE
This is the stage at which the Architect
set to commence the project and oversees
it to its completion. It also involve the
following:
 Mobilisation
 Construction to Practical Completion
 After Practical Completion

13. MOBILISATION
 Letting the building contract,
appointing the contractor.
 Issuing of production information to
the contractor. Arranging site hand-
over to the contractor
CONSTRUCTION TO PRACTICAL
COMPLETION
 Administration of the building contract
up to and including practical
completion.
 Provision to the contractor of further
information as and when reasonably
required.

14. AFTER PRACTICAL COMPLETION
 Administration of the building contract
after practical completion.
 Making final inspections and settling
the final account.

15. THE STRUCTURE OF WORKING
DRAWING
This defines the various sheets that make
up a set of Architectural Working Drawing.
Although, the structure and complexity of
the structure of Working Drawing Varies
depending on the Project type. Not all
projects will include each sheet
listed below:
1. Title and Legend Sheet(s)
2. Plot Plan (site plan)
3. Foundation Plan
4. Floor Plans
5. Roof Framing Plans
6. Details and Section Views
7. Elevations
8. Floor Framing Plans
9. Ceiling Framing Plans
10. Window and Door Schedules
11. Interior Elevations
12. Trade Plans (Mechanical, Electrical, Plumbing)
13. Specifications

16.  The title sheet will list the architect
(designer), owner, builder, and major
subcontractors, and it may include a
green home certification program’s seal
and the green verifier’s information.
 Other sheets in the plan set will use a
title block. The title block organizes
some of the same information from the
title page for quick reference on each
page. Page numbers will be part of a
title block to help keep drawings
organized.
