The rapid change in science and its methodologies are exciting, invigorating challenges
for architects. We are fascinated by the multi-layered aspects of contemporary human
inquiry. We become part of the commitment to make places that support and enable
scientific advancement and learning to improve the human condition. We strive for
our creative process to result in a place of creative discovery.
Designers who work on successful buildings for science approach this building type
from several points of view. As architects, we believe beautiful and humanistic
surroundings inspire creativity and intellectual achievement. As laboratory planners,
we strive for ideas that define new and innovative ways for people to work collaboratively,
efficiently, and safely in a highly technical environment. As campus planners,
we are thoughtful in how we place a new building on a campus because we respect
the character of its past and its future.

Laboratory Planning and Design
Laboratory construction, whether new, expansion or a renovation project is not simply
to buy a reasonable equipment, but also comprehensive consideration of the overall
planning of laboratory, rational layout and graphic design as well as electricity,
water, air, ventilation, air purification, safety, environmental protection, infrastructure
and basic conditions. Therefore, advanced scientific instruments, superior and sound
lab enhance the level of modern technology, a prerequisite for the growth of an
Institution.
Planning is divided into six areas: graphic design systems, structure and function
of a single design system for the drainage design systems, electronic control systems,
special gas distribution system, harmful gases such as six-output system.

The High Cost of Research
Buildings for science today are more sophisticated than yesterday's utilitarian
and functional 'research laboratories.' This is prompted by several trends:
|
|
1.
2. 3. 4.
5.
|
Scientific investigation has produced remarkable advances in all areas of science
and has resulted in increased funding.
New instruments, utilities, chemicals, and gases require specialized environments
and infrastructure.
There is an expanding need for shared core facilities such as analytical instrumentation.
Research programs have become multi disciplinary to benefit from the combined knowledge
of a broad range of specialists.
A consequence of these trends is high cost. Science labs are a major financial commitment
and an Institutions need to realize a return on investment, towards the community.

Laboratories Never at Rest
Why do science buildings need to accommodate change? If the average duration of
its research programs is three years, it is conceivable that up to 30 percent of
the building can be undergoing some level of intervention at any time. Intervention
may be required due to changes in research funding, changes in technology, recruiting,
promotions, mergers, acquisitions, legislation, etc. A particular basic science
research facility completed within the past two years has experienced changes to
29 percent of the net square feet during construction (before it opened its doors).
one.
Generally, there are three levels of intervention in terms of the cost of the changes:
|
|
1.
2.
3.
|
Cosmetic changes within existing rooms (such as repainting, new carpeting); upgrades
within existing rooms (such as new utilities, lighting, ceilings, carpeting).
Renovation where walls are relocated (all trades are affected).
In addition to construction costs related to the intervention, other costs may be
incurred for things such as 'down time' when the space is not in use, relocation,
assuring ongoing operations in adjacent areas and code upgrades.
|
|
|
A building designed with flexibility to accommodate change will minimize intervention
costs but it will also incur higher first costs.
|

...A key objective is to incorporate maximum amount of flexibility within budget
constraints and in the context of other priorities. Depending on the nature of the
project, it has been our experience that the following menu of choices can provide
cost effective results:
|
|
1.
2.
3.
4.
5.
6.

9.
|
Select a building layout that accommodates reassignment of space.
Consolidate uses that require special needs to the infrastructure.
Broaden application of design criteria to highest appropriate use.
Selectively build-in a 'robust' infrastructure.
Provide a mechanical distribution that accommodates change.
Provide a modular distribution of utilities with valves to isolate zones.
Provide repetitive modular design.
Select a cost-effective casework system.
Consider use of interstitial space.

|
The emphasis on interdisciplinary research has prompted social environments to be
an integral part of a science labs. Creative ideas come from discussions that can
occur spontaneously during a casual encounter.
In academic settings, communication amongst and between faculty, students, staff
and administration is essential to the education and mentoring process. In corporate
settings, communication between researchers, administration, and marketing is essential
to staying in business.

Worksurfaces
The SALWANS lab tops worksurface is a monolithic, modified epoxy resin product.
Our tops go through a special two-stage curing process. This method of curing assures
complete chemical reaction throughout the material, producing a uniform worksurface
of the highest quality.
The non-flammability, non-absorbency, superior chemical resistance and extreme durability
characteristics of our lab tops epoxy resin make it the material of choice for laboratory
and school countertops, tabletops, sinks and fumehood bases.
Our Laboratory tops offer epoxy resin / Laminate / Granite / Toughened glass / Corian
/ Fire resistant laminates / Fiber glass and polyvinyl chloride countertops to choose
from.
Almost any laboratory, school or production facility's countertops can be configured

Drain Tops
Our Drain top is a specially designed top section featuring a unique raised rim
on all four sides for control of spilled liquids. Outside edges and corners of the
drain top are radiused for user comfort and safety. Flexibly designed, drain tops
can be used at the end of islands and peninsulas or in a wall run section. The 30"
(762mm) long X 18" (457mm) wide sink area accommodates a large dropln sink.
The "ribbed" sections to the left and right of the sink area facilitates drainage
to the sink from an elevated surface. Drainboard sections of our drain top are designed
with rounded edges and gently slope toward the sink from all directions to facilitate
complete drainage and easy, through cleaning.
Dropln Sinks
Our laboratory tops offer the greatest number of epoxy resin topmounted Dropln sink
sizes. All exterior edges, corners and interior corners are rounded for the user's
protection. The clean lines and flush mounting of our Dropin sinks give a modern
appearance to both new and remodeled laboratories.
Flush mounted sinks eliminate the exposed area under the sink cutout where residual
chemicals gather and bacteria commonly form due to incomplete drainage and cleaning
oversights. This can result in uncontrolled chemicals mixing in the sink area. Our
sinks significantly decrease this hazard because of moisture are visible and curved
with no sharp hard-to-clean corners.

School/College Labs
General
Master switch - Near to a door in each laboratory, there must be a master switch
for the electricity and stopcocks for the gas and water so that supplies can be
cut off.
Design of sockets and taps - All Sockets and taps should be of a design and quality
which minimizes the effect of students abuse.
Devices on gas and water taps - Installation must be very carefully supervised to
ensure the contractors respect the devices on gas and water taps intended to prevent
them from rotating.
Gas
Gas Mains - Where possible, mains gas should be installed. If this is not available
then gas should be piped from cylinders placed outside the laboratory.
Gas outlet - The gas outlet chosen should be double one controlled by drop levers
or a spring loaded knob. It is important that it cannot be opened with an accidental
knock and that is possible to see from some distance when the gas is off.

Waste and Drainage
Water outlets - Water outlets should be at least 600mm above the bottom of the sink
so that all vessel can be fitted.
Fittings - At the same time the outlet must be close enough to the sink so that
water goes into the sink and not on to the bench.
Sturdy - Fittings must be sturdy and have no joints about which nozzles and necks
can be rotated.
No Joints Pillar Tap - The most trouble free type is the pillar tap. These are sturdy
and need not have joints. The fitting must have a square lug or fixing plate so
that the whole fitting cannot be rotated.
Traps - Sinks must be fitted with traps, which are easy to open for cleaning. Standard
plastic drain fittings are adequate for school laboratory use.

Fume Cupboards
Centrifugal fan near the exit - Fume cupboards should be evacuated by a centrifugal
fan near the exit from the duct as it is quieter and more efficient that an axial
one.
Its position - Fume cupboards should not be placed in the wall between a laboratory
and preparation room.
Must in every Lab - There should be access to a fume cupboard which can be used
for demonstration.
Relationship Within the Department
Centralized preparation room and storage - It is more flexible and less prescriptive
to provide a centralized preparation room and stroage.
Location (Near the centre of the building) - Clearly, if this is to have easy access
to all the laboratories, then it will need to be somewhere near the centre of the
building.
Natural light (a necessity) - Immediately we can see the problem of getting natural
light to the preparation room. People working in a space for a long time are happier
if they can see the outside.

Circulation space Circulation space provision for coats and bags - Circulation space
must be carefully considered at the same time as the provision for coats and bags.
Some of the circulation space may double as the display area.
How Big is a Laboratory
Needs will change (A large Laboratory advisable) - However, needs will change several
times during the expected life of a life of a laboratory and experience shows that
small laboratories are often used to accommodate the larger classes of younger pupils.
It is therefore probably better to build all laboratories the same size. A large
laboratory can accommodate a small class while the reverse is not true.
LABORATORY SIZE (Not separate form class) - 80 sq. m. for laboratory is ideal and
this should be regarded as a minimum.
LABORATORY SHAPE - Laboratory size cannot be considered separately from class size.
A useful rule of thumb allows 2 sq. m. of free floor area per students at age 11,
rising to 3 sq. m. at 16+.

This is one area that requires specialized construction expertise. SALWANS is the
recognized leader in this field with ongoing development of the SALWANS Laboratory
Furniture systems.
A simple alan-Key bench frame system using our standard components, reduces construction
time, requires no welding and creates no handling or transport difficulties.
A range of our systems enables the fixing of all service pipe work directly to the
bench frame - out of sight.
Due to bolted construction, if layout changes are required at later date, the system
can be dismantled and relocated with no damage to materials or finish, impossible
with a welded construction.
