在项目范围内至关重要的是通过严格的工程经济学实践制定项目预算和进度计划。利用CPM关键路径法 (Critical path method) 有70天的完整设计期。
Crucial in the project scope included the project budget and schedule development through rigorous value engineering exercises. Utilization of a CPM method produced a 70-day complete design duration.
扩容准备：由于场地有限，学校希望确保未来扩建是可行的。如未来需要更多空间，设计承载能力可承载更多一层。
Expansion Ready: Due to the limited site, the school wanted to ensure any future vertical expansion was possible. This design accommodates load capacity to carry another story if more space is needed.

悬臂倾斜屋顶一定角度，最大化二楼屋顶面，实现斜向光线的控制。
Implementing a cantilevered corner which maximizes the 2nd floor roof plane and thus also enabling the sloped light monitor.
提升机械设备，考虑到下方的绿色屋顶。
We also elevated the mechanical equipment to allow for green roof below.
有课间休息计划，所有室外游乐区均设计为可渗水的，包括橡胶化游戏场表面和组合铺砖的篮球场。
All outdoor play areas are designed to be permeable including the rubberized play surface and a modular tiled basketball court while still allowing recess program.
交通岛的生物滞留区处理来自建筑物周边和下车区的地面雨水。
A bioretention area at the traffic circle treats all surface storm water from the perimeter of the building and the drop-off drive.
所有人行走道表面均为透水铺装。
All walkway surfaces are permeable pavers.
节约成本的措施：保留了现有的体育馆地板，维修已损坏的区域，完美修复、承载了该区域的历史。利用现有建筑的一部分作为选修教室，以节省成本并与该项目共同使用。
Cost Saving Measures: Kept the existing gym floor and repaired and damaged areas, it has been beautifully restored and carries the history of the space. Utilized a portion of the existing building for elective classrooms to save cost and work with the program.
架空走廊：通过调查，实际连接两座建筑。这对学校的规划和现有建筑的基础设施运行最有意义。学校共用厨房和保健室，避免了多余的功能，节省了成本，为学生提供了更多的学习空间。
The Bridge: Physically connecting the two buildings was arrived at through investigation. It made the most sense for the school programmatically and with the running of infrastructure from the existing building. The schools share a kitchen and nurse’s suite, avoiding redundant program saved cost and gave more learning space to the students.
建筑的一角悬挑帮助实现了多个目标：有顶盖的室外座位区，供学生在上学前等待或上课时聚集；有更大的绿色屋顶面积，建筑后面有更多的游乐空间，因为建筑可以覆盖一部分下车区，面朝街面更受欢迎、更少被打扰。
The corner cantilever of the building helped us achieve multiple objectives: Covered outdoor seating area for students waiting before school or for classes to gather during school, a larger green roof footprint, more play space behind the building because the building can cover a portion of the dropoff circle, and a more welcoming less intrusive face to the street.
