FEDERAL BUILDING REUSE & RETROFIT
PART 1
OPENING STATEMENT
The Federal Building Warehouse is part of a larger complex built by the military in the early 60’s; it was
later transferred to NWT and subsequently to the GN. The warehouse is among GN’s largest asset in Iqaluit
having a footprint equivalent to 6,584m2 (70,870 ft2). In many ways the facility is outdated, although it
remains an excellent structure and a potential candidate for reuse and retrofitting. The following
document examines the feasibility of reusing and retrofitting the facility into multifunctional usage and
addresses the cost of retrofitting.
A study prepared by STANTEC in 2012 contemplated the reuse and retrofitting of the complex that included
NAC and the warehouse. The overall retrofit of the warehouse portion was then estimated at 28M$ 1 or
$4,220m2 and for which cost was unjustified, considering that office spaces accounted for only 20% of the
entire usage (see attached estimate and drawings). During the same period, another study was initiated
by CGS and this time looked at partly reusing and retrofitting the warehouse into 896 m2 office space.
Considering the anticipated scope of work, It was then estimated at 4.2M$ 2 or $4,687/m2 to retrofit
portion of the building. The following proposal reviews the initial scope and challenges retrofitting in ways
that may result into cost savings.
I view of the airport expansion and the new ATB air terminal scheduled to be completed by 2018, it makes
sense consolidating this asset into office space. Once the airport maintenance and fire station are relocated
in the new CSB building, this would free 1900m2 (20,500ft2) of the Federal building. The following proposal
keeps in mind two phases of the project, for which the second phase is active once the airport project is
completed. As seen hereafter the ATB complex is located in direct view of the Federal warehouse and NAC
building, making this asset a prime office space and once retrofitted a key figure to the GN.

FEDERAL BUILDING REUSE & RETROFIT
Reuse and Retrofitting versus leasing
Further discussed in the business case, GN combined department requirements for office space in Iqaluit
represents 20,620m2 (222,000ft2) from which 11,800m2 (127,000ft2) are leased spaces 3 representing
about 8.25M$ rent annually. Keeping in mind this aspect of the operational budget, one may want to
examine ways of reducing leased spaces. In this perspective there may be a merit of reusing existing assets
and more specifically the Federal Building. In view of this proposal, retrofitting the Federal Building would
keep in mind revolving stock, warehousing, workshops and 3,775m2 (40,634ft2) office space.
It is estimated that if relocating 962m2 (9,700ft2) low value storage space out of the building at $15/ft2,
this would still result into savings equivalent to 25% of the annual leases and at $65/ft2, this would
represent operational savings equivalent to 2.0M$ annually. Considering that a capital investment payback
period is equivalent to 10 times its revenues; reducing leased spaces and retrofitting the Federal Building
makes sense and seems desirable.
PROJECT SUMMARY
This proposal keeps in mind existing usages and operational constraints of the facility. Retrofitting is done
in two phases keeping in mind minimum disruption of key operations. In reference to the attached
drawings, the IT core, Operation and Maintenance offices, Records offices, and revolving stock warehouse
remain operational during the entire retrofit. Phase One of construction is scheduled in 2016/17 and is
limited to existing OM offices and vacant spaces that make up 950m2 (8,761ft2) office spaces. Phase Two
of construction is scheduled in 2018/19, once airport operations are no longer required. Workshops are
relocated and remaining spaces are reused as office space, providing a facility with 3,775m2 (40,634ft2) of
office space. General storage representing over 960m2 (10,330ft2) is relocated in other premises.

FEDERAL BUILDING REUSE & RETROFIT
Architectural premise – Open Office Concept
Keeping in mind the existing usage and operational constraint of the facility, new mechanical and electrical
systems are adapted to existing conditions. Building envelope is retrofitted and offices are planned as
open spaces.
The open office concept has been widely used in the past and embraced by many institutions, especially
when retrofitting older industrial buildings with higher ceilings. The concept has been shown successful and
if planned properly they are lively convivial work environments and by nature cost savings. As shown in the
following concept, office spaces are grouped in strategic clusters served by corridors. Each cluster may be
dedicated to a department or to multiple ones. Individual clusters are open spaces with workstations and
include 20% closed offices located strategically along corridor paths.
Constrained by the depth of the building, but advantaged by its height; natural lighting is redirected in
remote parts of the building with reflective surfaces. Open space mezzanines provide office cluster
separation and are used as quiet meeting spaces, office filing and for general storage. Along with simple
architectural expressions and unconcealed building systems, finishes and touches of colors are kept to a
minimum. Spaces, such as meeting rooms, washrooms, a small gym centre and other supporting spaces
are located at the Centre core where natural light is not required.
It is the opportunity of introducing mechanical strategies, low velocity air handling systems, unconcealed
ductwork and heat reclamation from the IT server room. Indirect artificial lighting provides a uniform
daylight, and localised lighting is introduced at points of interest. Task lighting is achieved from the
workstation. The underside of the roof deck is sprayed with a cellulose material which provides insulating
values, a reflective surface for light and acoustical qualities. Among other strategies, these are the
principles that may result into substantial cost savings. Reusing and retrofitting the Federal building is a
green process with respect to existing constraints.

Building description and Code overview
The existing Facility is a single story 6,584m2 foot print accessible on three streets. It is built on piles with
above ground concrete cap footings, beams and floor slab. There is an exterior crawlspace ensuring access
to utilities and retrofitting below the slab. The superstructure is composed of steel columns, beams and
trusses with a steel deck roof assembly. Original exterior walls are insulated metal pans with a metal
cladding and interior wood studs, drywall and blown in insulation. The building has presently a dry
sprinkler system that will be retrofitted into a wet system. Fire Safety systems will be retrofitted and
upgrade to latest code.
As per the 2010 NBCC , the building is classified into two major categories, one being Group F2 (3.2.2.75)
medium hazard industrial, comprising of workshops, revolving stock and records storage, and Group D
(3.2.2.59) business services category.
Fire separation is not required between both major occupations (table 3.1.3.1) although 1 hour fire
separation will be implemented around workshops, boiler room and the central core (see attached fire
separation plan A-4.0). The building will have active sprinklers and is classified incombustibles or
combustible construction or a combination of both. Steel Superstructure supporting the roof assembly is
not required to be fire rated and Mezzanines of combustible construction shall have a fire resistance of 45
minutes. Roof assembly is not fire rated although is protected with a K13 cellulose acoustical material.
Maximum travel distance to one exit shall not be more than 45 meter for Group F2 and 40 meter for
Group D. (3.4.2.5). Mezzanines shall conform to articles (3.2.8) (3.2.1.1) and (3.4.2.2) with a maximum area
of 500m2 and walking distance of 25m to the ground floor exit.

The condition of the roof assembly is based on visual inspection only. The roof had a leak in 2012
that was repaired. It was stated that the remaining roof membrane is in poor condition, the age of
this membrane is unknown therefore destructive testing is recommended to determine the
remaining life expectancy of the assembly.
Replace rigid insulation and membrane with sloped roof, upgraded rigid insulation and metal roof.
If it is not practical to financially replace the roof assembly, spray foam insulation should be added
to the underside of roof assembly to upgrade the insulation value to R40. Replacement of roof
assembly should be planned for near future depending on destructive testing of membrane.
Fire rating on the spray insulation may be required.

STRUCTURAL
Statement
The building is estimated to be 60+ years old. An interior only visual inspection/assessment was undertaken
to determine if the building and its structural members and connections have sufficient structural capacity
and structural integrity to safely and effectively resist all loads, effects of loads and influences that may
reasonably be expected from the re-purposing construction.
Existing conditions
The building foundation consists of concrete pile caps located in a rectangular grid at the underside of the
building. To borrow from the May 2012 Stantec Report (1) – “The existing foundation consists of heavy
timber pilings supporting concrete pile caps. The existing main floor structure is concrete slab and beams
supported by short concrete columns extending to the top of the pile caps.”
The building is a steel frame structure with a steel deck and open web steel joist roof system. The steel
beams supporting the roof joist are estimated to be about 14.6 m apart and the beam is supported by steel
columns spaced at about 7.3 m apart/intervals.
It is estimated from a number of existing small boreholes in the floor that the main floor is a mass concrete
pour (slab on metal deck). The concrete is about 400 mm thick - intended to support industrial loading for
warehousing, storage and equipment. 100mm thick rigid insulation is fixed to the underside of the metal
deck.”
No signs of structural distress, fatigue, deterioration or potential failure were observed in the steel framed
post and beam structure.
Recommendations
The building appears to be in excellent condition and has the structural capacity and structural integrity to
safely and effectively meet the requirements of the planned retrofit/renovations. If the retrofit involves the
construction of new mezzanines whose supports may involve columns that have not served that function
previously, then a full and complete structural evaluation will be warranted

MECHANICAL
Statement
New mechanical systems for the repurposed building will be required to provide a comfortable and safe
environment for the building occupants, meet diverse process and program requirements while being
robust, reliable and efficient. In deference to the cold operations climate and the remote location of the
facility these systems will, however, need to be simple in design, easy to maintain and repair and
incorporate equipment redundancy. In the facility there will be three main building mechanical systems;
sanitary, fire protection and HVAC. 4
Existing conditions
Sanitary and Water Distribution
Sanitary services for the facility will be from the municipal utilidor system, reusing the existing main
sanitary exit pipe. Potable and fire water for this office retrofit will be from the existing combined
water service main, which is located outside of the area of this project. Existing domestic water
distribution mains near to the area of work will be reused. 5 Recommendation R-1.
A new utilidette below the floor will be provided to enclose the exposed length of sanitary pipe and
will include heat tracing as a freeze prevention measure. Damage to the sanitary drain pipe insulation
and jacketing was noted during the site visit carried out on May 1, 2012. This insulation and jacketing
will be repaired, and the integrity of the drain pipe will be evaluated to confirm that it is appropriate
for reuse. A replacement sanitary pipe will be provided if further investigation concludes. 6
Existing domestic water distribution mains near to the area will be reused. 7
Fire Protection
Mechanical fire protection passive systems will encompass fire stopping and fire dampers, while active
systems will encompass hand held fire extinguishers and an automatic sprinkler system. Due to
concerns over the integrity of the existing dry pipe sprinkler system, and the expected cost of
modification, it is proposed that this system be removed over the area of work and replaced with a
new wet pipe sprinkler system with a direct connection back to the main distribution tree. 8
The existing office space is currently protected by a dry pipe sprinkler system which connects to the
main sprinkler distribution tree located remotely from the area of work. The option of modifying the

FEDERAL BUILDING REUSE & RETROFIT
existing sprinkler system and reinstating it based on the new office layout was explored. The primary
concern with this option is the possibility that moist, stagnant air has had ample opportunity to
corrode the inner wall of the distribution pipes over the years since installation. This concern will
trigger the need for a full evaluation of the existing pipe system and possible replacement of some
sections of pipe. Upon approval of the existing pipe system, it will be necessary to adjust sprinkler
head locations and associated branch piping to accommodate the new office layout. Any additional
sprinkler heads or substantial modifications to the existing layouts will require hydraulic load
calculation over the entire system in order to confirm the overall system performance under the new
operating conditions. These hydraulic load calculations will be complicated by the lack of record
drawings for the sprinkler system. Full system as-built drawings would need to be developed in order
to complete the required hydraulic calculations. Further flushing, testing and verification will be
required for the existing system prior to reinstatement. The cost of modifying and reinstating the
existing system is expected to be beyond the cost of a complete replacement system over the area of
work. It is therefore recommended that the existing dry piping sprinkler system is removed and
replaced with a new wet pipe sprinkler system, designed to accommodate the new office layout. 9
Recommendations R-2
Heating
Heating, ventilation and air conditioning (HVAC) is recommended through a decoupled air/water
system using hydronically heated air coils and traditional ventilation systems with ventilation heat
recovery. The HVAC system for the retrofitted office area will use a VAV distribution system supplied
by variable speed supply and return fans and an economizer mixing section. Ventilation recovery will
be provided by a stand-alone ERV unit. It is proposed that space heating is provided using a series of
cabinet style hybrid unit heaters located in perimeter spaces. The new hydronic system will be heated
using a new steam-to-water heat exchanger connected to the existing central steam heating system. 10
It is proposed that perimeter heating is provided by small wall mounted fan/coil units such as those
manufactured by Jaga. These units are essentially cabinet unit heaters but can be as small as only 13
cm deep, a similar depth to standard convector baseboard, yet they have small induction fans that are
barely audible, and the units are reasonably attractive in appearance. They would be located under
windows and elsewhere as required. The optional cooling function of these units will likely not be
required in this facility due to the viability of free outdoor air cooling. However, the option is available
in the future should cooling be deemed necessary. 11
It is understood that the premise for this report is that all existing services and infrastructure get
demolished and replaced with new. That being said, it should be noted that the existing central heating
plant is comprised of two steam boilers that were replaced in the 1984. They are well maintained and
in good condition, but they are at the end of their normal expected life according to the ASHRAE
Standard on life expectancies of mechanical equipment. In addition, it is understood that this is the
only central steam heating plant in Iqaluit that is maintained by CGS. The closest comparison is the

steam boilers at the hospital that only supply steam for the humidifiers there. The question is whether
it is desirable to continue to operate a steam plant with the diminishing maintenance expertise, and
difficulty in obtaining and storing spare parts for a one-of-a-kind system in Iqaluit. It is recommended
that the existing boilers be replaced and that the plant be changed completely to a hydronic system
rather than steam boilers and convertors for the hydronic heating to the terminal units that currently
exists. 12 Recommendations R-3
Ventilation and Cooling
A new ventilation system will be installed to the requirements of ASHRAE 62 and the National Building
Code of Canada. This new system will include new central air handling equipment, new ventilation
heating equipment, and a new air distribution system designed to accommodate the retrofitted office
layout. The system will incorporate several energy saving features to reduce the life cycle cost. 13
An economizer mixing section will be included on the main air handler to reduce the outdoor air
requirement of the system and thereby reduce the ventilation load on the heating system. Outdoor air
flow rates will be provided to the requirements of ASHRAE 62, to offer optimized indoor air quality
without sacrificing energy efficiency. The summer requirements for cooling were evaluated and it was
determined that free O/A cooling would be the most economically viable option; the expected cooling
loads would not be large enough justify the additional cost of mechanical cooling. The mixing section
will therefore be sized to accommodate a 100% O/A free cooling mode during the summer. 14
The new ventilation system will incorporate a Variable Air Volume distribution system to allow the
system to reduce the deliverable capacity during periods of low occupancy. This system will include
Variable Frequency Drive supply and return fans in the main air handling unit, medium pressure main
ducts and VAV boxes prior to discharge. VAV boxes will be sized for minimum and maximum air flow
rates as required by ASHRAE 62 based on both floor area and expected occupancy levels. Demand
control for the VAV boxes will be from local thermostats located within the offices. Additionally, VAV
boxes serving interior spaces will be provided with hydronic re-heat coils controlled by local
thermostats to allow a temperature control option for offices lacking perimeter heating. 15
Recommendations R-4
Control
A complete automatic control and alarm system will be provided for all the mechanical systems.
Control will be from the latest generation of web browser based Building Management System (BMS)
that will use BACNet open protocol communications making it suitable for interface to any third party
vendor equipment controls. The system will have a fail-safe design to ensure continued system

be a new web server PC that will operate both as the system server and as a web based Internet server
that will allow control functions, report functions, all database generation and modification functions
as described for typical EMCS work-stations to be completed via the Internet from any remote site
with Internet access. 17
For onsite diagnostics and control a PC workstation connected to the BMS will be supplied. After hours
monitoring and alarm system trouble will be reported through digital pager or email connections to
allow after hours communications to maintenance personnel for critical system trouble, i.e. heating
system failure. The BMS will also allow remote monitoring and control of the buildings through
Internet based communications. 18 Recommendation R-5

ELECTRICAL
Statement
As minimum, electrical systems shall be designed to meet the requirements of the current edition of the
National Building and Fire Codes (NBC and NFC), the Canadian Electrical Code (CEC), National Energy Code
of Canada for Buildings (NECB), Illuminating Engineering Society (IES) "Lighting Handbook" and any other
requirements of the local authorities’ 19s having jurisdiction.
Existing conditions
ELECTRICAL SERVICE AND POWER DISTRIBUTION20
The existing service to the building is 600 volt 3 phase with a 600 amp main breaker. The electrical service
to the building appears to have been changed in 1992 & appears to be in good condition. The building use
is not changing with offices being taken out and new offices being put in. As such the electrical demand
loading will not change; as such the electrical service should be sized adequately for the building in its new
configuration.
EMERGENCY POWER 21
The existing building does not have an emergency generator to supply loads in the event of a power
outage.
22
LIGHTING
Lighting is one of the electrical systems that building users are generally more cognizant of since it has a
direct effect on their use of spaces. Effective lighting must enhance the environment that is supportive of
work activities yet also be energy efficient and environmentally friendly. It is important that the choice of
luminaries and lamps be examined carefully for the ability to function with natural light, achieve colour
temperatures compatible with building finishes, control glare and shadowing, yet operate efficiently with
readily maintainable components.
The lighting systems shall be designed considering the light levels recommended by the Illuminating
Engineering Society of North America (IES) recommended practice 3 (RP3). It appears as though the existing
lighting in the building is done with 120 volt fixtures, this will be maintained in the renovated area.
Utilizing high performance high efficiency fluorescent lighting shall be maximized throughout the interior
areas of the facility. It is proposed at this time to use deep cell parabolic fixtures to minimize glare on the
computer screens. High power factor low harmonic electronic program rapid start ballasts shall be specified
to the extent practicable. Lighting control will be done with line voltage switches.
Exterior Lighting
There will be no changes to the existing exterior lighting. 23

To meet the NBC requirements, battery powered emergency lighting units complete with automatic selfdiagnostic circuitry; integral double heads with 20 W MR-16 lamps as well as remote double heads of with
the same lamping shall be designed throughout the building. AC light emitting diode (LED) type exit lights,
complete with integral back-up battery, which conform to CAN/CSA-C860 will be used to meet NBC
requirements and provide energy efficiency. These lights shall illuminate under both normal and
emergency power conditions.
PARKING RECEPTACLE SYSTEM 25
Under this contract there will be no changes to the parking receptacles at the facility.
FIRE ALARM SYSTEM 26
The existing fire alarm system is an Edwards’s 6500 system. The system is dated and it is now almost
impossible to find replacement parts for the system. It is recommended that the whole fire alarm system
be replaced.
SECURITY SYSTEMS 27
There will be no provisions for a security system in the building.
STRUCTURED WIRING 28
Rough in will be provided to accommodate category 6 structured wiring system for voice and data
communications throughout the building. The supply and installation of active and passive components of
the system and wiring will be the responsibility of the owner. Deep 100 mm x 100 mm outlet boxes for
telephone and data will be provided complete with 27 mm conduit & pull string stubbed out to accessible
ceiling space. An arterial system of wire mesh cable tray located inside the accessible ceiling space will be
designed to facilitate wiring between the stubbed up conduits and telecommunication spaces. Short runs of
open wiring through properly located approved J-hooks would be considered as the means of transporting
cables from conduit over the arterial cable tray.
CABLE TV DISTRIBUTION29
There will be no provisions for a cable television system within the building.
Recommendations
The existing electrical systems and related sub-systems of electrical installations of Federal Building are
original and require complete replacement due to “non-conformance” to the current NBC, CEC, NFC NECB,
IES codes & standards requirements. It will be most economical & cost effective to include substantial
upgrades or complete replacement to avoid potential systems’ functional performance failures through the
next extended life cycle of the office Building. The following electrical system and associated components

must be integral part of the expected renovations scope because of code compliance and improved energy
efficiency:
1. Electrical Services: The existing service to the building from QEC of 600 volt 3 phase with a 600 amp main
breaker is in good condition and electrical demand loads will cater new office configuration. However all
existing and anticipated loads calculations in accordance with CSA C22.1-12 for the electrical service should
be performed during the phase 2 of the project in consultation with to determine if that service is adequate
or if it has to be upgraded for extension of the overhead & underground primary line to the transformer,
secondary raceway, conductors as well as the grounding The main service entrance equipment including
disconnect will be replaced with moulded case circuit utilizing solid-state combination thermal/magnetic
overcurrent protection .All transformers should be of proper KT rating for Phase Shifting Transformers in
compliance with the minimum efficiency values requirements of CSA-C802.2 . As QEC power systems are
relatively small, closed systems, they are prone to a greater number of power anomalies than in the
integrated, open network systems elsewhere; therefore surge protective devices (TVSS) be provided in the
main service/distribution panel board as well as in branch circuit panel boards supplying sensitive
equipment.
2. LIGHTING: The lighting systems must be designed considering the recommended practices ANSI/IESNA
RP-1-04 and “Lighting Handbook” of the Illuminating Engineering Society of North America (IES). The
choice of luminaries and lamps should be examined carefully for the ability to function with natural light
achieving colour temperatures, control glare and shadowing with readily maintainable components.
All feasible means to optimize electrical energy consumption should be pursued in designing lighting,
utilizing high performance high efficiency linear compact fluorescent luminaries with high power factor low
harmonic electronic program rapid start ballasts should be specified throughout. A two level lighting
control and to optimize energy efficiency, use of occupancy sensors, day lighting sensors and dimmable
ballasts allowing selection of a lower level intensity when higher level is not desirable should be proposed
throughout the building. LED could be used for accent lighting and special purpose spaces.
3. PARKING RECEPTACLE WITH INTEGRAL TIME AND TEMPERATURE CONTROL: Intelligent programmable
receptacles should be provided for automobile receptacles. The on/off duty cycle of the receptacles will
vary with outside temperature, with additional time control being provided to allow receptacles to be
switched off during selected days or times of day. The suggested system would provide the necessary
protection for staff vehicles parked for long periods of time while maintaining the highest level of energy
efficiency as IPLCs deliver up to 65 percent in energy and cost savings
4. Fire Alarm System: The fire alarm system should be modular type architecture to accommodate all
phases, zones, single stage, non-coded; fully addressable designed to meet the requirements of the
National Building Code for this building.
5.EMERGENCY POWER: Standby generating set of an appropriate size be provided at later stage of the
considering the power failures & anomalies, long enough periods of downtime to cause freezing in the
buildings causing substantial damage and costs.
6. STRUCTURED WIRING: A category 6 structured wiring system to conform to the Government of Nunavut
Community and Government Services (CGS-IPS) Structured Cabling Guidelines Version 1.5 2012
Department of Community and Government Services
21
FEDERAL BUILDING REUSE & RETROFIT
7. SECURITY SYSTEMS: A video surveillance system with high resolution fixed colour cameras in interior
specific spaces where important records and valuable assets are stored and exterior cameras should be
considered at the main entrance and other security sensitive locations of facility during the next phase of
the project
8. SYSTEMS VALUE ENGINEERING 30: This report provides general recommendations on systems utilizing
value engineering developed on past and current projects. For all projects, project specific value
engineering should be used to confirm final mechanical systems selection accounting for variances
between projects. Special emphasis should be placed on the value engineering of energy based systems.
9. FACILITY ENERGY PERFORMANCE 31: Energy costs are exceptionally high in Arctic communities. To ensure
long-term facility viability for the office facility the recommended minimum energy performance is 50% or
greater energy savings for the building, referenced to the Canadian National Energy Code for Buildings2011.
This level of energy savings can be achieved in the building systems for Arctic infrastructure construction
using proven systems with the emphasis placed on improving efficiency rather than applying esoteric or
unproven technologies in Arctic conditions.

CIVIL WORK
Statement
Positive drainage away from the building is required to avoid the accumulation of water around the
footings which may degrade the permafrost and put the structural integrity of foundations at risk 32. To
minimize the transfer of the heat released by the underside of the building, a clear space is mostly provided
between the base of the heated structure and final grade to permit air circulation. More parking area will
be needed to accommodate the revised occupancy of the building.
Existing Conditions
ACCESS TO THE SITE
The site at the Federal Building consists of a gravel parking lot located on the north and south of the
building. A small section of asphalt paving is also located near the south elevation. The building has
concrete ramps which provide access to the overhead doors. The building has metal stairs providing access
to the doors located on the north elevation of the building. There are also, metal ladders which are
attached to the side of the building providing access to the roof. Concrete ramps and loading dock ramps
and stairs shows signs of wear and tear 33.
SITE CONDITION
Site is not well graded and sign of accumulation of the water can be seen under the building. Debris is also
found in the space underneath the building. Spring runoff needs to be catered.
PARKING AREA
Parking area seems to be sufficient for the present users of the building but needs to be expanded as per
the revised occupancy of the building.
SIGNBOARD
At present there are few signs posted on the exterior wall which are not visible from the distance.
FLAGPOSTS
Currently there is no flag post with any flag at the location.
Recommendations
ACCESS TO THE SITE
Concrete ramps, loading dock ramps and stairs needs general renewal and renovations as a part of general
site work 34.

FEDERAL BUILDING REUSE & RETROFIT
Re-grading of the site is suggested for proper drainage of the site. Culverts made of corrugated steel can be
installed to discharge the spring runoff to the nearest channel located on the Southern side. For the proper
circulation of the cold air to refreeze the active layer during winter, a clear space underneath the structure
needs to be maintained free from debris and hoarding of the materials, which needs periodical removal or
wire mesh can be constructed around the building.
PARKING AREA
As per the GBPG 35 , traffic circulation to be controlled by the traffic signs and sufficient on-site parking to be
provided. Finished walkways should be provided; leading from the edge of the roadway and all parking
areas, to all regularly used building entrances. Surfaces should be well drained and finished with contained,
finely crushed granular material, or pavement. Concrete, paving or grating surfaces should be considered at
entrances. Vehicle routes and parking areas on site should be clearly marked, using physical barriers that
remain visible in winter conditions if necessary. Parking spaces could be increased as per the Zoning By-Law
of the City of Iqaluit 36.
SIGNBOARD
A visible sign board is desired at the site in all the official languages with civic address of the building and all
relevant required information to show the presence of the Government of Nunavut.
