A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. G E N E R A L I N F O R M A T I O N
This family fallout shelter, designed primarily for homes without basements, is a
permanent home shelter to be placed in the yard. It is designed to have a protection
factor of at least 40, which is the minimum standard of protection for public shelters
throughout the United States. This assures that persons inside the shelter will be
protected against radioactive fallout following a nuclear attack, and
1
will also have some protection against blast and fire effect of nuclear explosions.
Following are detail drawings of the shelter, which is capable of housing six adults.
It can be built of poured reinforced concrete, precast concrete slabs, or a
combination of concrete blocks and poured concrete. If it is built as detailed with
the top near ground level, the roof slab can be used as an outdoor patio. The
shelter is accessible by a hatch-door and wood stairway. Fresh air is provided by a
hand-operated centrifugal blower and two ventilating pipes that extend above ground
level. In areas where there is poor drainage or where the ground water table is
close to the surface, the fourth modification on page 5 should be used.
Before starting to build the shelter, make certain that the plan conforms to the local
building code. Obtain a building permit if required. If the shelter is to be built by
a local contractor, engage a reliable firm that will do the work properly and offer
protection from any liability or other claims arising from its construction.
G U I D E T O C O N T R A C T S A N D S P E C I F I C A T I O N S
It is generally advisable to have a written contract with your contractor, as well as
technical specifications to supplement the drawing. A widely used and convenient
contract form for construction of this size is the AIA Document A 107, “Short Form
For Small Construction Contract -Stipulated Sum, " which is available from the
American Institute of Architects, 1785 Massachusetts Ave., Washington, D. C.
20036. It would be impractical to write a technical specification to suit every
local condition; however, the following summary of generally accepted construction
materials and practices should be a useful guide.
E X C A V A T I O N
The excavation should have side slopes gradual enough to prevent caving, or
appropriate shoring should be provided. Materials used for backfill and
embankment should have debris, roots and large stones removed before
placement. The subgrade for the floor slab should be level for ease in placing
waterproofing membrane and to provide uniform bearing conditions for the
structure. The area surrounding the patio should be sloped away at a minimum
grade of 1 inch per 10 feet to provide good drainage.

This shelter will withstand overpressures of up to 5psi, and provides excellent
protection from tornadoes.

3. CONCRETE
For details of concrete construction, the “Building Code Requirements for
Reinforced Concrete/ (ACI 318 - 71)” should be followed. This publication
can be obtained from the American Concrete Institute, Detroit, Michigan
48219.
WATERPROOFING
Waterproofing specifications may be obtained from the nearest FHA (Federal
Housing Administration) office, or those of a reputable manufacturer of
waterproofing materials may be used.
VENTILATION
The ventilation piping for the shelter should be installed in accordance with the
practices outlined in the “National Plumbing Code (ASA A40.8 - Latest
Edition). " This publication may be secured from the American Society of
Mechanical Engineers, New York, N.Y. 10018. All pipe and fittings shall be
galvanized. Suitable ventilating blowers and roof ventilators are available
from many sources of supply. Fabrication details and consequently the
installation requirements will differ for equipment furnished by the various
manufacturers. Positive-displacement blowers having both electric motor and
geared hand-crank drives have been manufactured by:

OPTIONS
To accommodate additional persons, increase the shelter length 2’-6” for each two (2)
shelter spaces. Do not increase the 9’-4” width.

4. Electrical serv ice for lighting and outlets may be installed in the shelter from a separate
residence circuit. A branch circuit breaker should be installed inside the shelter.
Additional lighting and outlets may be provided from this circuit’for the patio above.
An electric motor and pully may be installed to operate the centrifugal hand-crank
blower by virtue of the electrical service option.

Exterior walls, roof slab and under floor slab shall be waterproofed with a 3-ply membrane
waterproofing system. This provides a continuous blanket which seals the entire area of
surface to be protected. The membrane shall be protected from backfill damage and when
completing other stages of construction.
Place flagstone or bricks on a sand bed when using the roof slab as a patio.
There are a number of commercially produced metal roof hatches that will adequately
serve as a shelter door. However, as long as the door is weatherproof and durable, a job-made,
galvanized sheet metal covered wood door is suitable.
Bevel all exposed corners of concrete 3/4” at 45’.

MODIFICATIONS
This first modification utilizes 12-inch
concrete masonry units for walls instead of
reinforced concrete. The floor, roof and
entranceway are the same as in the basic
shelter, and the amount of protection
provided is essentially the same.
If a basement is available, the shelter may
either be separate from it, or attached. In
this modification, an attached shelter is
entered through the basement of the house,
thereby permitting dual use of the shelter
space. Other advantages of this
modification include flexibility of shape
and design to conform to the house design
and the use of the same kind of building
materials as used in the construction of
the house.
If the topography permits, the shelter can
be built into a hillside or embankment.
This modification increases the protection
factor by the addition of an earth mound
over the shelter. A maximum of 3 feet of
earth cover is recommended.
The principal advantage of this shelter
modification is that it can be erected with
a minimum of excavation in locations
where there is poor drainage or where the
ground water table is close to the
surface. However, the exposure of
the shelter above ground requires
the addition of earth mounding
around all sides.
This shelter modification permits the
design and construction of a shelter with
a fairly small hatch entry. The iron rungs
placed in the concrete wall will also
maximize the useable shelter area.
