扩大MCEC-澳大利亚最大的大会和展览空间

Author:Tamara Stakic

这Melbourne Convention and Exhibition Centre (MCEC), located in Australia, is undergoing an expansion to help the world’s most liveable city retain its position as the meetings and events capital.

这20,000平方米的扩展包括9,000平方米：

• Flexible, multi-purpose event space
• 新展览厅
• Additional meeting rooms
• A banquet room
• A new café and bar

When completed the new space will cement MCEC’s position as thelargest convention and exhibition space in Australia,增加总尺寸超过70,000平方米。

这expansion is part of a larger South Wharf expansion project that includes a new 347-room Novotel Melbourne South Wharf and a新的1,150空间多层停车场– all fully connected and integrated with existing buildings. The car park is complete, and the new hotel recently opened.

维多利亚州政府为MCEC的扩张提供了2.05亿美元的AUD，该州的合作伙伴全体会议及其合作伙伴旗舰物业控股公司和附近中心正在新的酒店和停车场投资超过1.5亿美元的AUD。

总部位于墨尔本的钢制制造商Stilcon是该项目从事该项目的众多本地公司之一，该公司由Project Builder Probuild参与制造和安装整个钢骨架，以供新展览馆，会议中心和停车场。

Stilcon提供完整的钢铁套餐- 钢铁工程处理，弯腰和绘画，到达现场的运输以及最终的现场勃起。所有这些都是由他们在墨尔本西部的设施中的制造来完成的。

Central to Stilcon’s work is thefabrication of five 85-metres-long trusses，每个重量超过70吨。每个桁架由八个21米的模块组成，高度从5到10米不等。

成品，包括4,300吨结构钢，combines the highest levels of strength with structural integrity and manoeuvrability for safe, stable installation.

A progressive approach to deliver a complete steelwork package

To speed erection times and create better safety exclusion zones onsite in Melbourne’s busy central business district, Stilcon employed a more progressive approach to constructing the steel frame for the new four-level carpark.

事实证明，钢勃起方法是一个至关重要的时间节省方面，使立面承包商和混凝土可以在现场进行无限制并与钢铁厂承包商并行工作。Stilcon站点工程师Adam Tierney解释了这种“垂直方法”的重点是结构的一部分的全高直立建筑，该建筑物又在建筑物的宽度上复制，采用相同的主要方法。

Stilcon adopted the approach to allow trades to access the full height structure earlier, while the steel erection crew could work a few bays ahead, rather than the more common horizontal floor-by-floor build sequence. Increasing the number of bays built also provides a safety buffer zone between steel erection and follow-on trades, which is an Occupational Health and Safety (OHS) requirement on the site.

“平坦的'水平'方法是传统上大多数其他多层次停车场建造的方式，使钢或混凝土散布地板区域更宽，限制了多个工作阵线的能力，”蒂尔尼说。

垂直构建方法涉及首先使用全高（13米高）的圆柱构建单个方格舱，并进行一些临时支撑，以实现垂直勃起。从最低的水平开始，所有主要和二级成员均竖立，导致完整的四级高钢湾工作。

初始海湾完成后，然后将二级湾结构置于两个方向上，使Stilcon更快地完成了一块海湾，将其移交给了随后的商人。

In this case, the metal decking was laid first on level two followed by level one. While metal deck laying was occurring on level one, the reinforcement placement began on level two. The slab was then poured on level two, creating a safety deck between the upper and lower structure.

然后安装了钢筋，混凝土倒在一级上，以及安装人员在第二级上工作的安装人员为第三级铺设的钢甲板。

从地面上

为了提供关键的时间节省和准确性，Stilcon转向Madigan测量师，Madigan测量师是一家专业的测量公司，为建筑行业和盟友专业人员提供全面的服务。Madigan测量师使用地理系统解决方案精确地设置了所有钢连接到现有结构 - 从圆柱锚螺栓和基本水平精确设置为水平连接到现有的结构板边缘或墙壁。

地理系统解决方案用于管理与现有结构的连接的施工布局，以确保建筑团队正在努力工作，而不是设计。

In addition to捕获产生的条件, as-built surveys captured newly built structures as part of the quality保证程序and to also set out existing walls for any member connections.

Due to the higher flexibility and movement in steel structures, the survey scope also includedmonitoring of the main exhibition hall roof trusses.

在整个构建周期中，对桁架进行了监测。在监视阶段，项目团队在最初的架子最初处于自身体重下，在初始勃起阶段捕获了桁架的叛逃。在屋顶，桁架覆层和可操作的壁系统上加载到桁架上时，进行了进一步的监测。

Simple layout, easy setup

Stilcon also recently purchased the iCON robotic construction total station due to its ability to tie neatly into established building construction workflows andrapidly speed up installation preparation and construction tasks.Stilcon测量师Andreas Caleta的解决方案。简单性和易用性。

Leica ICR60有一个简单而指导的设置例程设计用于最小使用错误使用户对防误设置的例程有信心。

“图标机器人总站是最快，可靠且易于使用的布局解决方案，使其成为建筑专业人士最有生产力的单人布局解决方案之一，他们需要将任务定位并将设计带入现实，”卡莱塔说。
