Comparing
the OLD
and NEW
SANS Building Regulation
After
Belgium introduced an energy conservation amendment to their regulations, it
has had an international knock on effect. Now, South Africa has adopted our
version of these ‘‘guidelines’’. It falls into Section X of the SANS
10400. This section aims to conserve the amount of energy used by the
building through the design of the structure. This is a very controversial
subject as these regulations hold the architect fully accountable if the design
and calculations do not comply with the XA regulations. Although Section X is a
great initiative and needs to be implemented in this day and age, most
professionals in the industry are unhappy with it. This is because the
Regulations limit the design aspect, e.g. (windows sizes need to comply with
room sizes and so forth.) it also insists that further calculations need to be
adhered to which means additional forms need to pass to through council. Below
are a few amendments to Section A thus to adhere to section X.
The amendments to section A;
A7 (Layout Drawings)
(M) In the event of a water heating
system installation, the location and capacity of the water heating system must
be provided.
(N) Where provided, details of insulation
are required to satisfy the energy requirements of section XA.
A19 (1) (Competent Persons)
(C) The requirements of section
XA are satisfied by a competent person in accordance with SANS
10400 XA
A19 (12)
(C) Where regulation XA is satisfied by a
competent person in accordance with the requirements of SANS 10400 Part XA, the
competent person who is responsible for such determination shall on completion
of the construction and commissioning of the building submit to the local
authority a fully completed Form 4 as contained in SANS
10400 – A.
Section X
Section X as mention previously was
solely implemented to regulate energy efficiency within the process of building
a structure and to ensure the final structure is ‘‘empathetic’’ to the
conservation of energy. Overall this section will strengthen the movement to
green alternative in South Africa and hopefully making an impact on conserving
energy globally.
A1
(Energy Usage in Buildings)
Buildings being
occupied shall be designed and constructed so that buildings;
(A) are capable of using energy
efficiently while still fulfilling its requirements
(B) have features and services which
facilitate the efficient use of energy
A2
States 50% of hot water heating must be provided by means
other than electrical resistance heating, this includes solar heating, heat
pumps, heat recovery from other systems or processes and renewable combustible
fuels.
However the Requirements of the above A1 regulations fall away
if the building is designed to be self sufficient in terms of energy efficiency.
The role of an Architect, (with
regards to duties and responsibilities)
A brief description/definition of an architect is a person who designs
spaces for habitation.
However, the role of an architect in reality is much more complicated
than that. Architects have a vast variety of duties and responsibilities within
the work place. Although this depend on what the architect has been contracted
to do!
Once qualified as an architect, a professional should have the knowledge
to perform the following duties and responsibilities;
·
Visualize clients wants and needs spatially
·
Create aesthetically pleasing environments in
context to surroundings
·
Prepare conceptual experiences for clients e.g. (conceptual
sketches,model,3D renderings etc) and be able to sell the idea to the client
·
Experiment and research options in terms of
concepts, material, and historical precedents.
·
Create local authority drawings
·
Be able to measure and survey area
·
Manage a team on and off site
·
Be able to manage a project
·
Create working drawings
·
Understand materials and specifications and
implement this in detailing
·
Corresponding with other professionals within the
built environment
·
Understanding and completing paperwork
·
Need to understand current economics and create,
run and manage a business with long and short term aspects in mind.
The list goes on; in essence an architect is solely responsible for the
process of all aspects within the project. Thus he/she needs to have an
understanding of every aspect of the construction and processes of the project
to manage it successfully.
Tender Documents
A tender document is an agreement between multiple parties in terms of
services to be done over a certain period. E.g. an architect would have
multiple tender documents with different companies for the services they do
towards the development and construction of a building. These tenders will have
quoted prices. The documents are then presented to the client who will approve
one or more for the work. This is normally the companies which offer the best
value for money. This decision is advised by the architect to reach a safe
selection. A letter is then created by the architect to inform the companies
that did or did not receive the tender.
This is all done in writing to help the architect if a legal dispute
occurs. A tender document only comes into play once the client is happy with
the design it has passed through local authority standards and
regulations. The documents may include
many subcategories, such as;
·
Tender Procedures
·
Returnable Documents
·
Forms of Guarantee
·
Pricing Data
·
Scope of Work
·
Site information
·
Advertised Tender Date
·
Closing Date and Time
Bill of Quantities
A bill of quantities is a document provided by a quantity surveyor, in which
a tally of all materials is evaluated to an estimate cost. This is to work
within the budget of the client. If the cost is too high, a meeting is to be
set up with the client explaining the process, a decision is met by either
agreeing with the cost or changing materials or designs to work within the
budget. A quote to for labour is normally included in the bill of quantities.
This should give the client a good estimate of the total cost of the
project. Normally a small leeway is given to as a ‘‘back up’’ fund to tap into
in the case of incidents which are not planned for. This once again is used to
cover the architect and help the project run smoothly without delays regarding
finance. This fund is normally added to the commission for the architect.
Singing of Contracts
Before the commencement of construction a contract between the architect
and the builder is drafted. This legally binds the builder to the terms and
conditions within the contract. An example of a clause in such a contract would
be that the builder will be fined a predetermined amount for every day the
project runs over its deadline. Once again this legally protects the architect
from possible problems with the builders or companies working on site. Once the
final stages of the building are completed and the client and architect are
happy with the final result the architect will issue an official document which
will conclude the original contract between the builder and the architect.
Thereafter it is very hard to take any legal action again the builders unless
an agreement in the previous contract has been broken.
The architect and clients signature must be on every drawing thus
legally binding all parties to the project. Thereafter the architect will
oversee and sign any changes on plans to make alterations from the original
plan official.
