In addition, the demand for dining space

requires that the school Gym is unavailable

for PE activity for long periods of the day,with many classes having to be escorted to

a remote playing field within Kelvingrove

Park. Therefore, the potential for additionalspace for indoor or outdoor physical activity

is explored within this report.

The report utilises record informationavailable to PM&D at the time of writing,including PDF copies of the original

Architects drawings. It is noted that some

minor discrepancies exist between theseand the completed school.

A visual inspection only of the Engineeringinstallations was conducted. Further

analysis and consideration of the completed,

Structural and M&E Designs will be requiredbefore any of the proposed options are

investigated further. Particular emphasis is

placed on the Fire Engineering solutionserving the original design, which permits

single means of escape from a number of

points on the upper floor. Increasedoccupancy capacity may exceed the Fire

Engineered design. Furthermore, unknownStatutory Design and Planning constraints

may have influenced the height and form of

the original school designs.For this reason, PM&D recommend that the

original building designers are fullyconsulted during the next stage.

1.0 Introduction

Due to increasing demand on pupil places atHillhead Primary School, Education Services

have requested DRS PM&D identify

potential options and associated costs toaccommodate additional teaching spaces

within the constraints of the schools existing

infrastructure provision and confined site

boundaries.

The Primary School is originally designed for

a capacity of 632 pupils, but the current role

is 652, requiring that the two GP rooms arefully utilised as Class Bases at present. The

Head Teacher has advised that the role

projection for year 2017/18 is 714, which willresult in an overall shortfall of three teaching

spaces.

Existing toilet provision is at a minimumacceptable level to satisfy Building

Standards and would remain so if theprojected Primary School role of 714 was to

extend into the Existing Nursery. However,

should the Nursery remain within the schoolcampus, the toilet provision will need to

increase.

An immediate and potentially short term

solution to the increasing capacity isrequired prior to the beginning of term in

August 2014. This is the subject of Option 1.

3.1 Option 1A

Formation of Class Base and ICT

Breakout Space within existing

Library (required August 2014)

Form free standing teaching wall as dividingscreen between rooms (with cable drops),

but conditioned as a single space.

The Head Teacher has reported that the

room overheats due to a predominance of

Reglit glass.Review of air con installation is required in

view of apparent inadequacy of existinginstallation.

Include full height vertical louvre blinds

throughout to mitigate comfort issues.Further review required with original

Designers to offer comment and propose

resolution.

Review of fire engineering strategy is

required due to the increased design loadingcapacity.

PM&D to obtain Fire Engineers report for

analysis.

Note, room has limited outlook due to

predominance of Reglit glass. Should thisoption be a permanent solution, PM&D

recommend the incorporation of additional

windows, requiring Planning Consent.

OPTION 1B

Retain Library as oversized Class

Base

Retain room as a single space / oversized

classroom, with alterations / upgrades as

necessary to M&E installation.

3.2 Option 2

Formation of Dance Studio w ithin

Undercroft Car Park

Note, headroom restrictions (2600 to u/s

beams + 900mm beam depth [excludes new

sprung hardwood floor make up].Two means of escape to be provided from

basement.

Access, including DDA, to be provided fromexisting adjacent functions, such as

changing facilities.

Existing access available via lift, externalstair from ground floor roof terrace and car

park entrance.

Note, the potential exists to form a newenclosure to the existing adjacent external

stair to provide direct covered access

between the Dance Studio and changingrooms.

Adequacy of existing changing provision tobe reviewed.

New windows to external wall, formed within

existing louver vent openings.Mechanical extract from car park may be

required due to reduced cross ventilation.

Resultant net reduction of 8no car spaceswithin car park.

3.3 Option 3

Formation o f single Class Base / GP

room enclosure over Social Space.

Partial infill of void permits borrowed light

through to ground floor and maintains

double height spatial quality at the mainentrance.

Clear storey glazing to corridor walls for

borrowed light into classroom.Glazing to back wall for borrowed light.

Connection to vent stacks at high level to be

explored.Assumes new structure can span across

void between existing steel.

Allow for two means of escape due todirection of travel via voids.

Option 3A

Form new partial floor infill only, with halfheight partitions as open plan ICT breakoutspace.

OPTION 3B

Ground floor Social space

Proposal to create ICT study booths alongcorridor sides with informal debate seating

within main body of floor.Include allowance for sliding folding screen

to entrance side (optional).

Option may require formation of additional

table and chair storage to facilitate further

flexible use of the space.



3.4 Option 4

New Gym Hall, and GP rooms

The Option is subject to the successful

purchase of the adjacent domestic property.

Existing adjacent dwelling and associated

structures to be removed.

New building formed to accommodate Gym,

Drama and GP space.Circular plan form proposed, clad inmatching facing brick, to compliment the

existing Architectural response and avoid

the impression of narrow alleyways betweenbuildings.

Direct access to Gym and GP room is via

the existing bridge link and in close proximityto changing rooms within the Community

Block.

Direct access to the Drama space isprovided via a new bridge link, which also

offers a second means of escape from the

Gym.The need to tie in floor levels will result in a

deep underbuilding, which may be

considered for use as additional parking,storage and sheltered external play space.

The option will be subject to Planningconsiderations, daylighting issues and the

proximity to the neighbouring churchbuilding.

Further consideration is required with regardto the adequacy of the existing changing

facilities.

Option 4A

Form outdoor Multi Use Games Area withassociated fence enclosure in lieu of Gym

building.



3.5 Option 5

Al terations to Ex isting Nursery to

Accommodate 3 Primary Classrooms

Existing partition layout, generally, to be

retained, providing 2no Classrooms at 75m2

and 1no at 66m2.Small toilet within one of the existing

classrooms to be removed.

Reconfigure access to existing unisex toiletand convert to girls only. Sanitary ware to be

replaced with adult sized units.

Form small store off toilet access corridor.Form dedicated Boys Toilet within former HT

room.

Breakout extension.

East flank Classroom block extended

southwards by a single classroom on bothfloors, with small Breakout space on Ground

floor and Unisex Accessible Toilet at First

Floor.Extension to be clad in facing brick to match,

creating a stop end to the existing

Architectural form.

Reconfiguration of final escape door andexternal steps required.

Note, accurate location of the site boundaryadjacent to the proposed extension

is subject to further research. Access and

footpath width may require widening.

Include contingency sum for retentionstructure at river bank to widen footpath.

External views from existing Nursery Staff

Base is compromised.

External play area reduced.

Option to be considered only if Option 5,

expansion in to Nursery, is not feasible orclassroom numbers are not adequate.

3.8 Option 8

Formation of single classroom

extension at first floor.

Extend the southern classroom block

Westwards, at first floor only, to provide 1no

additional classroom.Proposal permits access around perimeter

of building and avoids reduction of outdoor

play area.The already stretched fire Engineering

solution for the building will require a second

means of escape is provided from the farend of the first floor corridor. This is

achieved via an external bridge spanning on

to the western landscaped embankment,with a platform which connects to the

existing access steps from Kelvin Way.

The proposal is subject to further analysis of

available headroom at ground leveland adequacy of toilet provision at First

Floor.
