Construction Communication PPT

1. Construction Activity
Documents

2. Tutor Copy

3. There are construction documents that are
designed and formulated to aid in planning,
organising and coordinating all the various work
activities and operations necessary to complete
a job of work within an allocated time and within
an agreed budget.
These documents are therefore very important
to both the builder and to the person requiring
the building, the client.

4. Whatever level of planning is involved,
there are four main questions to be
answered:
1. What is the work or task to be done?
2. When is it to be done?
3. Where is it to be carried out?
4. How is it to be done?

5. Finding the answers to these questions is the
most important part of the planning process.
Not knowing the answers will:
• Make it difficult to organise work activities.
• Lead to lost time and money.
• Result in failure to purchase materials and
equipment.
• Have an effect on the planning and
organisation of an efficient workforce.

6. The construction activity documents are
known in the trade as the contract
documents, and they are designed to control
building activities. They are:
• Architect’s Working Drawings
• Programme of Work
• Specification
• Bills of Quantities
• Schedules

7. Scaled building drawings or plans
called the architect’s working
drawings which include:
• Survey maps.
• Layout or block plans.
• Site plans.
• Location drawings.
• Assembly and component drawings.
• Construction details.

8. Programme of work
This often in the form of a bar chart showing:
• The work to be done.
• The order in which it is to be done.
• The estimated time allowed to do the work.
Here is a simple programme.

9. Specification
These are detailed descriptions of the
construction processes, giving precise
information about materials and
workmanship. The specification provides
additional information that cannot easily
be shown on the working drawings.

10. Example of a
door lining
schedule
A typical specification for this lining would be:
150 x 38mm wrot rebated door lining in European
Redwood, moisture content 8% to 12%, fixed to
preinstalled slips with two 62mm brad nails. The
nail heads to be well punched below the surface,
and the surface being free from blemishes. The
surface of the lining is to be prepared to receive a
priming coat of paint. The lining is to be protected
from other trades.

11. Bill of Quantities (BQ)
A quantity surveyor prepares this document. As the name suggests, it
contains a description and the measurement of quantities, labour and any
other items required to carry out the work. All the work is measured from the
working drawings, specification and schedules.
Within the bill, there are certain sections that relate to specific information.
The Preliminaries section deals with:
• Names of the client and architect.
• Name of the builder and where they operate from.
• Any other interested parties.
The Preambles section outlines:
• What kind of materials that should be used.
• How they are prepared and stored.
• The quality of the materials.
• The quality of the workmanship.
The main section concentrates on the measurement of all necessary
materials. This document is NOT kept on site.

12. Here is an
example of items
that relate to the
work of the
carpenter.

13. Schedules
On most contracts, there is work which may be
repetitive, such as hanging doors and fitting
ironmongery, fixing and fitting radiators, installing
windows, fixing and fitting sanitary ware, and
finishes. These repetitive items are identified from
the working drawings, and set down in the form of a
table.
The schedule will contain certain information such
as:
• A brief description of the item.
• The location of the item.

14. Grouping like items together makes it
easier to determine the number and
types of components needed.
On most contracts, items such as
doors are identified using the prefix ‘D’
for Doors’ and ‘W for windows’
Therefore D1 will be Door1 and W1 will
be Window1 and so on.

Hatching / symbols are used to cut down on lengthy wording.
