170 THQ Commercial and Childcare Project
2018 - Wallace managed the Structural Build for our long time clients, Stratum on this 3 story commercial and childcare development in Thorndon Quay. With no piles required we formed and poured over 700m3 of concrete in the foundations of this solid building which is 130% of the building code. 20T concrete panels were formed and installed around the buildings perimter and the floors were formed using ComFlor 80 supplied and installed by our Wellington Studwelders division (www.wellingtonstudwelders.co.nz)
Whitby Lakes Stage 5 Apartments

The National Biocontainment Laboratory
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.
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 400x400 concrete columns on each level and a curving concrete ramp which will provide access to the Levels.
Wellington Airport Terminal Extension
2016 - Wallace was engaged by Hawkins Construction to undertake the concrete works to the Wellington International Airport southern extension to the Main Terminal Building. It was a new and significant project for Wellington Airport and the first major work to the Main Terminal Building since its opening in 1999.
Wallace designed and built the formwork for around 80 Insitu concrete columns ranging from 500-500mm up to 800x800mm. A mixture of Insitu and 16T precast beams were installed over 2 levels and stitched together with hollowcore and Flatdeck for the floor structure.
As the Airport has to be able to load and unload planes until around 11:00pm a lot of the major floor construction was completed at night over the baggage handlers roadway. Also noisy works such as scabbling and drilling had to be undertaken in the early hours of the morning to not disrupt the 15000 passengers travelling through the airport each day.
There was also upgrades done to the southern gates 9,10 and 11, A new pedestrian walkway down to the Sounds Air access with Hammerheads, ramps etc and works to the Existing façade on the runway side to allow installation of the Huge trusses that were installed over top of the existing terminal building.
2016 - Wallace Building Contractors formed the concrete slabs and walls for this 34 unit Townhouse Development in Newtown. The townhouses were constructed in 2 stages with Stage 1 comprising of 22 townhouses in 6 blocks on a relatively flat site. Stage 2 involved an additional 12 units in 2 blocks built into the side of the hill with anchored retaining walls and large footings.
With all units sold off the plans work was fast tracked to complete the project in time for the Developers next project.

Weltec School of Construction
2014 - Wallace was contracted by Maycroft Construction for the manufacture and installation of the precast panels for this new build in Petone. Due to the large infrastructure projects underway in Wellington Maycroft could not find a precast yard able to produce the panels to meet the tight program. WBC proposed to form the panels onsite on an area of slab and are nearing completion of the 52 panels. Wallace also constructed the mezzanine floor of the building which includes large 350mm thick insitu cantilevered slabs.
2013 - Another project with Stratum Management this complex consists of two 5 story apartment blocks housing 44 apartments and eleven 2 story townhouses. Constructed with a mixture of Interspan and ComFlor the apartments feature stunning views over the Basin Reserve and while the boys were busy constructing them over the summer they enjoyed catching a glance of the New Zealand cricket teams superb efforts.

Wright St Townhouse Complex
2012 - Concrete works for 20 townhouse units in Wright St, Mount Cook for Stratum Management. The sloping site iwas extensively excavated to create a large flat site for the townhouses yards, carparking and public spaces. This involves the use of multi level concrete retaining walls some up to 5m high and 400mm thick. Due to the height of the excavation cuts a lot of the excavation and construction of the retaining walls has to be staged and involves extensive underpinning and temporary.
