Boatshed Drive at night. (Site is circled) Image sourced: http://www.mercantile.org.au _INTRODUCTION The site is located along the banks of the Yarra River at 5, Boathouse Drive on the prime real estate just south of the city. The Mercantile boatshed is one of seven buildings that occupy this prime river frontage and has occupied the space since its establishment in 1880. After a fire destroyed the boathouse in 1973, the existing building was constructed on the site and has remained largely untouched for 40 years. The internal refurbishment is long overdue as the club was run-down and dingy, emanating outdated 70’s aesthetics and was no longer fulfilling the functional requirements of its club members. Whilst the major structure remains largely untouched, the renovation will provide brand new state of the art gym facilities, coach office spaces, 4 large bathroom/change rooms, a new bar and service area as well as a newly decorated function space. The construction process also involves the addition of an external lift shaft and entry staircase as well as the addition of a kayak shed as a sub division of the rowing club. The overall structure of the building, whilst remaining untouched, dictates the internal design of the building. The building is supported by the three load bearing walls on the east, south and west sides that integrates with the steel frame that connects to the foundations and supports the roof and floor spanning systems. The façade is deceptive in that it uses its materiality to emulate the boatshed style of the pitched roof and quaint weatherboard façade however, the scale of the building is too large to be supported in this style and therefore transitions to a more sturdy masonry wall system towards the rear. Similarly the roof system transitions from a pitched gable roof to a flat roof that assists in the transfer of load from the roof into the walls and down to the foundations. Internally, the refurbishment is focused on the upper level whilst the ground level, comprised of five boat storage bays will remain largely untouched except for the addition of an extended storage space. Construction works will be conducted over a five-month time frame and the estimated cost of the project is $1.7 million.

Existing structure to remain the same. Construction focuses on the refurbishment of the interior, addition of a kayak shed and installation of a lift shaft on the eastern side of the building. No changes to be made to exiting foundation and footing system or overall structure. Existing supra structure consists of steel columns and beams that operate along both the horizontal and vertical planes of the building. Only minor modifications to the overall structure: previously the first floor deck extended from the external wall point of the ground floor. In the refurbishment, the first level external wall and deck remain the same, however, the ground level external wall has been extended to the extent of the deck. This creates an extra storage space without increasing the overall footprint of the building Addition of lift shaft on the eastern side. Doesn’t interfere with the primary structure as it connects to the external staircase (refer image 1). Similarly, the kayak shed on the east side is supported by additional infrastructure that is then attached (bolted and welded connections) to the main support system Steel structure is left exposed as seen in the thin red columns supporting the deck/roof and the thick green beams that span the width of the building (refer image 2). The connections are bolted/welded joints. The roof seen from the façade is a pitched gable roof using a corrugated sheet metal as the external finish. This medium sloped roof creates an ideal run-off flow for precipitation. Given that the corrugated sheathing is ribbed, it is likely that the roof will require purlins to run perpendicular to the ribbed surface. The southern half of the building is flat roof that allows access for maintenance of surfaces such as air conditioning and ventilation units etc.
2_MATERIALS -
External cladding: weatherboard replaced in some sections External lift shaft wall: steel member frame cushioned by two layers of fire-proof plaster board. (refer image 1). Then covered with kiln-dried hardwood weatherboard that has been treated with water-proofing agents. Important to retain character of ‘boatshed style’. (refer image 2.) Internal wall cladding (function space): stained hard wood to match existing décor (refer image 3,4,5) Internal walls: Timber stud walls + plaster board with a painted finish (refer image 3, 4)

3_CONSTRUCTION SYSTEM AND FUNCTION OF MEMBERS -
Large steel beams align from foundations through to the level 1 roof Timber gable pitched roof channel is revealed through the central axis (pictured above in image 2) Open web ceiling joist trusses span the width of the roof (refer image 2) to solid concrete block masonry walls (refer image 3: southern facade). These open-web joists are supported by the masonry bearing walls on the east and west side of the building which transfers the load of the roof through the walls to the foundations. These open trussed webs permit the passage of mechanical services. There are 3 primary joists that run east-west through the building and are secured to a “steel bearing plate that is anchored to the wall” (Ching, 2011, 4.21, 6.12). In this instance the floor and roof systems are merged as the open-web steel joists serve a dual function between supporting the roof of the ground floor, the floor of level 1 and the roof for level 1. The truss is a structural frame based on the “geometric rigidity of the triangle” (Ching, 2008, 2.16). The roof structure from the ground is deceptive in that a satellite view of the building shows that it transitions from a pitched to a flat (refer image 4) roof meaning it uses both pitched and flat truss systems to support the two different roof structures. Both truss systems are designed to transfer the static load of the roof and the dynamic load of wind and rainfall (Ching, 2008, 2.08) to the load bearing walls and steel columns and through to the foundations.

Pitched roof is context appropriate. Similar aesthetic to neighbouring boatsheds In a row of 7 two-storey boatsheds of similar scale. Slightly weathered exterior (dirt stains, flaking paint etc.) shows evidence of ageing Louvre windows replaced on south wall (refer image 1): allow much more natural light into the space. Steel structure extending through windowsill emphasises how the main structure will not be altered whatsoever (refer image 1).aa Original bar retained and reconfigured to fit new space. Provides a sense of continuity and history for the club. Installation of new louvre windows makes the space much lighter and creates the illusion of spaciousness. Also highly effective for cross ventilation through the north-south axis.

No major changes to structure from Week 1 as expected. Roller doors fitted to bays (refer image 1). This uses the coiling door system that consists of “horizontal, interlocking metal slats guided by a track on either side and open by coiling about an overhead drum at the head of the door opening� (Ching, 2011, 8.13). The handles on the exterior (refer image 3) would suggest that the doors are to be operated manually. Some formwork removed from beneath the external staircase (refer image 2). This image is from week 1 and shows the formwork providing assistive support whilst the connection strengthens. Image 3 shows the exterior of the ground level and shorted extent of the deck overhang. New steel architraves have been inserted to house the roller doors. Existing structure (beams) run perpendicular to the length of the deck to support the cantilevered deck as indicated by the red arrow.

The diagram above explains the modification of the lower level that increases storage space without increasing the overall footprint of the building. The existing spoon drain and the gentle slope towards it means the construction of the new extent is simple and does not require major changes to drainage infrastructure. By this simple extension, the lower level gains invaluable storage space

Image 2 and 3 show the same doorway but image 2 is from week 1, whereas image 3 shows the development with the plaster finish. Image 4 shows a sketch of the internal wall stud detail that is seen in profile in image 2.
This diagram shows a section view of the north facing exterior wall where the roller doors have been installed. The wall is supported by the 5 minor steel columns that mark the 5 bays and the two major steel columns on the east and west points of the building. The roller door requires a solid steel frame which is then finished with a plywood infill (30mm thick) before the roller door runner line which sits inset of the frame. The exterior is the traditional timber weatherboard. After the exterior has been painted, the door frame will be fitted with a steel architrave frame that will conceal the layers of the section. Below the break line, the diagram illustrates (not to scale) the relationship between the wall and the existing spoon drain.

New columns installed to support added load of level 1 refurbishment. Columns aligned and connected through the floor. Image 1 shows the interaction of the two columns and the bolted connects. The columns divide the internal space up and dictate the formation of rooms. The central line of columns through the building marks the division between the gym and the function room. The 50/50 split leaves a generous portion to both sections and is used to its full advantage. Image 2 illustrates the added infrastructure used in the ground floor to support the roof joists. Added columns (blue) are joined by another perpendicular strut that spans between the columns and gives assistive bearing support that relieves any additional stress on the walls. The function room and the gym are separated by the use of an overhead door that can act as a wall when shut and be removed and stored in a position above the door opening as required. This technique had been effective in the previous design and therefore was retained in the new design. Whilst the current design has transparent vision panels, the two sides will be finished with a different glaze. On the gym side, the glass panels will be covered with a mirror finish whilst the function space will be covered with an opaque finish to provide both a visual and physical barrier between the two spaces. The door frame and panels are in a lightweight metal, most likely aluminium and can be operated manually. (Ching, 2011)

Concrete slab on ground floor has been painted in the club colours with a non-slip screed overlay. Creates bold and vivid impact and is effective in the context. (Refer image 1) Storage racks installed. (Refer image 1). Image 2 shows the detail of the connection of the horizontal beam to the vertical column. This shows a moment/rigid connection that resists is resisting translation and rotation at the connected points. This is a common connection for column and beam intersections, as it must remain fully rigid for structural stability (Vassigh, 2008). Internal paint job beginning: the extensive white/cream creates a spacious feel. Decrease in deck area is questionable. This asset has been hampered by a desire for extra storage space. Decking looking faded and tired. Needs to be washed and stained.
