Completed 2021
Due to start Sept 2019
2019 – Wallace completed the Concrete and Formwork on this new 8 story apartment building. Situated on a tight site on Kent Terrace the heavy foundations and car-stacker pit are all beneath the road with Shotcrete and tanking required around the buildings perimeter.
4m high Insitu concrete walls and columns around the Perimeter of the Ground Floor carpark encases the structural steel frame and providing the required bracing of the building. All formwork was supplied and installed by Wallace Building Contractors.
The upper levels are ComFlor 80 with through deck welded studs with the ComFlor supplied and installed by our Wellington Studwelders division.
Wallace Building Contractors has been contracted by Fletcher Construction to build the new 10 story carpark building and Concourse at the Wellington Airport.
With the 38,500m2 carpark and the 9500m2 two story concourse At 48,000m2 This will be the largest building built in Wellington since Te Papa. The Carpark will be constructed with huge Precast Beam/Column units. Some of these are up to 23 Tonne per unit and will be installed with a 400T crawler crane. However the building is not completely Precast with 8,600m3 of insitu concrete in the Carpark and 2400m3 of insitu concrete in the Concourse there is a total of 11,000m3 of concrete being poured in the project.
The Carpark is to be built in 3 stages due to the size of the building and the required crane access. The 4000m3 Raft Slab will be formed first in 5 stages from April – June 2016.
Stage One of the Carpark Building will be constructed from May – November 2016 and another 9 floors will be built which will include 2 Ramps running from the Ground to the top floor. The 1.5m deep raft slab will be poured and insitu columns will be formed 3m high under the Mezzanine floor and up to 9m high up to the precast column Connection on Level 2.
Stage Two will then be built from the Raft Slab up to the roof which incorporates a stair and lift tower plus a large curved ramp on Level 2-3. Stage 2 will be built from November 2016 – March 2017.
The Third Stage will then be constructed from March 2017 – September 2017
In addition to the main Carpark Building starting in May the first Stage of the Concourse structure will be constructed. This involves 1300m3 of large column pads and foundation beams, 900 dia insitu concrete columns up to 6m high and a mixture of Precast and Insitu Beams to the Concourse upper level. The First stage will also involve the construction of the first of the 2 large Entry/Exit Ramps with 450mm thick insitu concrete walls. The First Stage of the Concourse should be completed in September 2016.
Stage 2 of the Concourse is completed once the Third stage of the Carpark Building is underway and involves the Same construction methods as the first stage of the Concourse but with the addition of 700mm deep curved insitu edge beams. Also included in this stage is the new Entry Ramp to new carpark and connection and ramp onto the existing Airport Terminal Concourse. This Stage will be undertaken from January 2017 to October 2017
2018
2018 – Wallace Building Contractors under its Wellington Studwelders division installed ComFlor over 16 levels for this Office Building at the site of the old BP House. The BP Building was damaged in the Seddon Earthquakes when the stairwell disconnected from the side of the Building. Engineers found the building was too extensively damaged to save and so it was demolished to make way for this new 18000m2 16 level office tower.
The building was designed by Dunning Thornton using base isolaters on top of new piles in the old BP house basement. The Steel frame used was a new “Diagrid” system eliminating most internal columns in the building to provide large 1200m2 floor plates.
ComFlor 60 and 80 was specified as the flooring system and with over 18,000m2 and 35,000 shear studs, it was the biggest ComFlor project ever undertaken in Wellington to date.

One Market Lane
2013 – One Market Lane sits on a landmark island site at the edge of Wellingtons waterfront and in the heart of the city. Prominently located on the corner of Taranaki and Cable Streets. Wallace Building Contractors was specifically sort by main contractor LT McGuinness due to our history in Wellington High Rise construction to complete the concrete works for this very innovative post Christchurch earthquake “low damage” concrete design. The 6 level high podium structure is constructed entirely in concrete with over 3500m3 of concrete and using the latest seismic design including forming multiple hinge joints to column/beam connections and a flexible 450mm thick corewall the entire 12 floors of the building.
High quality apartments are located on the top 6 floors of One Market Lane and the structure is lightened to Structural Steel with over 7000m2 of Comflor 80 flooring installed with through deck studwelding installed by Wallace.
2013 – Wallace completed the concrete and Comflor on Stratum Managements tallest building so far. With 16 floors Elevate Apartments is the tallest residential apartment complex built in Wellington and the most high tech incorporate cutting- edge new earthquake strengthening technology.
Elevate includes precision-engineered steel springs at the base of each of its structural wall frames. The springs, imported from Germany, will cushion earthquake vibrations and allow the building to weather a quake with minimal disruption. Wallace Building Contractors cast in the steel base connecting beams with a +/-0.5mm tolerance required.
A mixture of interspan and over 8000m2 of ComFlor 80 is used in the concrete floors and as Wellingtons Comflor Metal Tray flooring installers Wallace we had Elevate racing up to the top floor to set a new bench mark in Wellington high rise construction.
2012 – Construction of a 6 level very high quality apartment complex with 2 levels of Carparking in the Basement levels for Stratum Management.
Wallace has been involved in construction of this high quality apartment complex in this difficult to build on site. The Basement levels have been constructed right to the boundary against established buildings. Wallace produced the tall Pre-cast wall panels and erected them on site while only excavating small areas of the bank with the use of No-fines concrete as backfill allowing waterproof tanking to be installed in a controlled condition. Due to the amount of ground work involved the building was staged in 2 sections then caught up once nearing completion of the final floors.

Republic 1 & 2
2010 – This 138 apartment building was built in 2 stages with a building footprint of 2400m2 and 3 levels of carparking for Stratum Management.
The buildings were constructed with large concrete shearwalls and the Stahlton flooring system. Once construction of Republic 1 was underway Wallace discussed with Stratum the possibility of starting work earlier than planned on the mainly carpark structure in the south tower of Republic 2.
The developers were keen to see the project advance and it meant the code of compliance issues arising from an unfinished carpark for Republic 1 was negated and the settlement date for purchasers on the first tower was brought forward two months, with completion of Republic 2 also earlier with handover ready at the end of June 2011.
2008 – This 10-story complex houses 146 mostly 3 bedroom apartments and has a floor footprint of nearly 2500m2. Wallace was the Concrete contractor for Stratum Management and is their biggest project to date. It was constructed with an underground basement carpark with perimeter insitu walls and foundations going 1.2m below sea level. The two buildings were constructed as one large podium structure up to level two with two 8 story towers above. Each tower has a large core shearwall system of 60m3 per floor. The two lift core foundation pads are 600m3 pads 1.6m deep.
2007 – This high quality complex was built to look like 3 small apartment blocks along Oriental Parade. It had 2 floors of car parking under the ground with concrete perimeter walls and 3 core shearwall systems for each building up to the 5th floors.
2006 – This 10-story apartment complex was constructed with large exterior concrete walls and stahlton rib flooring system. It also included an underground basement.

VUW Gateway Building
2017 – Wallace completed the formwork and were the concrete subcontractor for Fletcher Construction at the 12000m2 Gateway Building at Victoria Universitys Kelburn campus. Wallace Building was engaged to undertake the enabling works to prepare for construction on two large sites. This involved Crane Bases for the 2 tower cranes and retaining works.
The Southern Zone was built literally into the side of a hill. Wallace constructed the suspended crane base early to allow construction of the 15m high anchored pile wall. 600mm dia piles were drilled into the ground to suit the existing topography and Wallace extended these piles up by forming 600mm columns up to 10m above the existing ground level. We also installed the 500m2 of timber lagging behind the columns to allow backfilling of Kelburn Parade
The Northern zone has been excavated approx. 6-9m deep into the existing carpark for construction of the large basement area which will eventually have the Culliford Drive over top of the basement roof. We installed the 200+ precast panels around the perimeter of the basement levels and the large shearwalls. Other work involved in the basement are the footings, panel stitches and insitu columns.

Gibson Sheat Carpark
2017 – Wallace Building Contractors completed the formwork and were the concrete subcontractor for Naylor Love on the Carpark Building behind the Gibson Sheat Centre. The 5 level Carpark is being constructed around the back of the L shape building to provide carparking and strengthen the existing building.
A 750m3 concrete raft slab up to 1500mm high was installed behind the existing building on concrete piles with 11 full height shearwalls installed around the carpark. Some of the Shearwalls were up to 500mm thick and were constructed with one sided formwork against the existing building. Permanent steel formwork was installed in the existing window openings and the new concrete shearwalls were connected to the existing building with long threaded bar installed through the existing buildings concrete beams and floors.
The Steel frame structure had all columns encased in 400×400 concrete columns on each level and a curving concrete ramp which will provide access to the Levels.
2017 – Wallace Building Contractors were proud to be involved as the Concrete and Formwork subcontractor to Fletcher Construction for The Ministry for Primary Industries new, high-level biocontainment laboratory in Upper Hutt. Situated at the National Centre for Biosecurity and Infectious Disease (NCBID) in Wallaceville, the $87 million investment will provide assurance to our trading partners that New Zealand remains free of diseases that could stop our animal products being accepted offshore.
High-level biocontainment laboratories are uncommon. They are highly complex and required to meet a range of international standards for the safe handling of high-risk infectious organisms including keeping a close eye on construction details and maintaining the highest levels of quality assurance.
The new lab is designed to survive a one in 2,500 year earthquake. It’ll meet the same earthquake protection requirements to withstand an earthquake as hospitals, airport control towers, and water treatment plants. The building will sit on 10 base isolators and 20 slider bearings to reduce damage and protect biocontainment during an earthquake.
Insitu concrete beams sit on top of the base isolators contained inside concrete rattle space walls. The ground floor beams are anchored to the ground with four 1.8m dia hold-down piles with metal strands coming out of the piles 14m below ground and allowing the building to move sideways in a large earthquake but provide anchorage to the ground.
The floors above are 2200m2 of 200mm thick F5 finished insitu concrete floors with thickenings at penetrations and the steel beams to encase the steel framed upper structure. High quality formwork was produced in our Porirua workshop and installed on site in prefabricated units. The floors are a highly specified concrete design requiring 30 days of water curing.

2013 – Wallace was asked by Arrow International to undertake the seismic upgrade of Cumberland House at 235 Willis St due to our previous experience with strengthening works and resources available in a very tight timeframe. The student accommodation building seismic strengthening involves two sprayed concrete Shearwalls 5 floors high the full width of the building, self-compacting concrete spandrels and upgrades to the existing columns and floors. The seismic upgrade of the building was not originally planned when the building’s interior was due to be refurbished over the Students summer break due to the impending sale to overseas owners and Wallace had to commit to having the strengthening work completed by the first week of February. Work started in December 2012 one week behind schedule and Wallace worked all through Christmas with a large crew of staff and subcontractors and finished the strengthening works Three weeks ahead of schedule on the 16th of January 2013. Arrow has expressed their gratitude at the hard work and professionalism that Wallace showed to allow them to complete the buildings refurbishment on time.
This existing carpark building was seismically upgraded in 2003 to allow the construction of 5 stories of apartments to be built on the top of the carpark. Wallace was involved in the construction of new 300mm thick Shearwalls built between existing concrete columns, Insitu concrete walls poured against existing concrete walls with scabbled and epoxied starters. Concrete columns and foundations were strengthened and a new 8m long shearwall was built 2 floors high on the top of the carpark for the new steel and timber apartment structure. All of this work was undertaken without the closure of the carpark.

Greening of the Quays
2007 – This Contract involved the forming of 1.5km of decorative concrete road islands along the length of Aotea and Jervious Quay. Work was completed under the Higgins Contractors Traffic Management plan from 9:00 – 3:30. The work involved exposed aggregate surrounding newly planted Pohutukawas with cast in wind delfecting screens and cast in up lighting.
2005 – Wallace Building Contractors was involved with Higgins Contractors in the road widening upgrade of SH1 in Paremata with the construction of a 700m long decorative concrete retaining wall at Goat Point from Paremata to Plimmerton. The Work was undertaken in an area between SH1 and the railway main trunk line. Due to the tight confines of the working area available we produced a rolling and lifting formwork system to pour the wall.
The formwork involved a specifically made steel mould to produce a pattern along the wall at a constant RL as wall height increased and decreased. It was lifted into place by winches on a specially built mobile Gantry, which was clad for all weather protection and safety from trains. This methodology was employed as the wall was in some places just 1.5m from the train tracks. The Gantry moved along a track bolted to the concrete footing and was poured in two 5m sections every 2 days.
During the excavation and construction of the wall foundations work was completed within 100mm of the North Island main fibre optic cable. Enhancement work was completed along the length of the wall including a galvanised steel pedestrian barrier,lampposts footings and cast in sockets for steel lampposts.
2006 – This Contract was for the removal and construction of the Black Creek Bridge in Wainuiomata as part of the Stream widening contract awarded to Dixon & Dunlop. Wallace removed the old footbridge and constructed new bridge abutments on 30m piles then craned in the new Precast Bridge and completed with handrails, paving and landscaping.
Wallace Building Contractors involvement in the Porriua stream flood protection was as the main contractor to the Wellington Regional Council. The work undertaken involved the realignment of the stream and concrete floodwalls through the City Center.
The realignment included building up new stop banks with conditioned fill and placement of Rip Rap Rock to both sides of the wetlands at the mouth of the stream. The concrete floodwalls were constructed to protect the neighboring commercial buildings and had a decorative finish to both sides. The contract also included a large area of landscaping which involved the building of timber walkways over the wetland area and the complete planting of the 2.5-kilometer length of the stream flood protection works.
This contract, completed in 1994 was the biggest workload that Wallace Building Contractors had taken on at the time. The contract was completed on time and within the Council budget. During construction we encountered a 5-year flood and all our temporary works held well. We had temporary walls and bunds along with flow over weirs crossing the stream.
