一篇国外博客上的帖子

由于我的博客的内容比较偏，本来土木工程就是个冷门，而我写的还是土木工程中的一类，所以一直以来博客的流量都很少，最近忽然发现有两个IP来自于清溪长河，这是一件很不寻常的事情，因为他的网站有很多链接，而他用了Hot Friends的软件

，只有留言多的人才能上到首页，我又不爱留言，因此从来就不是在首页上了，所以能有IP来自他的博客，是件很奇怪的事情。上他网上看了下，原来是他刚发了篇：世界最佳的30个土木工程博客。我的流量原来是来自这里。

帖子里面介绍了不少国外的不错的博客，不过可惜主要还是关于软件或者是技术的，关于工程管理的很少。不过其中有些博客中写了很多作者的职业经历，这个倒是挺有意思，我忽然想，如果我也来写写这几年的经历，相比也应该会受欢迎吧。

其中在一个年轻的工程师的博客中，我还真找到了一篇叫做：Construction Management的文章，作者是个很年轻的工程师，他的本身工作是施工项目上的设计师，也就是画shop drawing的，关于工程管理的观点，是他请教的另外一个人，我引用一下：

Houston Neal reviews the latest construction management software at SoftwareAdvice.com. His goal is to help organizations in the AEC (Architecture, Engineering & Construction) industry make the right technology decisions. I asked him some questions about construction scheduling – specifically about a new program, called Synchro, that promises to combine traditional scheduling tools with Google Sketchup.

Who is responsible for project scheduling on a large construction site?

Construction managers are primarily responsible for project scheduling on large construction projects. They work closely with the building owner, architect, general contractor and engineer to develop a detailed schedule, construction task sequence and project budget during the construction planning process.

What is the critical path? How does this improve project efficiency?

In construction scheduling, critical path represents the construction activities and sequence of activities required to complete a project. It is the minimum amount of time needed for construction, and is calculated by determining the duration of each individual activity. Project managers need to consider predecessor relationships and resource constraints in order to properly sequence construction activities and assess the duration of a project.

There are often thousands of activities going on simultaneously during a construction project. Critical path scheduling helps managers allocate resources and labor to each activity, optimizing the time spent on each activity and ultimately affecting the duration/efficiency of a project.

What does Synchro software do? What is the goal of the 4D Project Scheduling program?

Synchro is a 4D (3D + time) construction simulation program that combines 3D drawings with a construction schedule, then displays the progression of construction over time. This helps project managers and stakeholders visualize construction and gain a better understanding of the spatial and temporal aspects of the construction schedule.

How would adding a 3D representation (Sketchup) of the building improve project planning?

3D modeling allows designers and architects to visually test ideas before they’re implemented. It provides a realistic representation of a project and often provides key insight into potential delays and miscalculations.

What other new project management tools do you foresee coming to market in the next 10 years?

The technology behind rich Internet applications is becoming more accessible and affordable. As a result, smaller software vendors will implement these technologies into their own systems. We’re already seeing increased adoption of web-based project management systems among AEC companies. With broadband Internet becoming more available and reaching “utility-class” service levels, we expect this trend to continue.

Using the Software Advice website, construction firms can identify and compareconstruction project management software products that meet their unique requirements.

在这篇文章中，他提到了一个Synchro的计划软件，这是现在计划软件研究的方向，就是将进度计划和3D的图形结合起来，这样形成一个四维的模型，现在的计划软件你看到的是横道图和时间坐标的对应关系，而在这种软件中就是建筑的立体图形和时间的对应关系，虽然这种软件现在还很少真正在工程中应用，但是确实是一个很好的课题。如果有兴趣可以上这家公司的网站中去看看：官方网站。
