Nomenclature 用词

  1. "Substructure" generally includes all work up to the structural top levels of the lowest floor slabs, but excludes floor finishes thereon.
    "基础" 一般包含最底层地板结构面标高以下的所有工作，但不包括该地板面饰面
  2. "Superstructure" generally includes all works above the structural top levels of the lowest floor slabs, and includes floor finishes thereon.
    "上盖结构" 一般包含最底层地板结构面标高以上的所有工作，包括该地板面饰面
  3. "Lowest floor slabs" means the lowest floor slab at a particular location: 
    "最底层地板" 意指在某位置的最底层地板：
    • Ground floor slabs will generally be the lowest floor slabs in the absence of a basement
      一般来说，若没有地下室，首层地板便是最底层地板
    • The bottom slab of basement will be the lowest floor slab
      地下室的底板便是最底层地板
    • The lowest floor slabs may not necessarily be of the same level； they may have different levels
      最底层地板的标高不一定是完全一样，它们可能有不同的标高
    • Walls and columns between two adjacent lowest floor slabs at different levels should be regarded as part of the Substructure while the walls and columns above the higher of the two lowest floor slabs should be regarded as part of the Superstructure.
      相连但标高不同的两块最底层地板之间的墙及柱应归入基础，而高于该两块底层地板的墙及柱应归入上盖结构
  4. "Basement" generally includes all works above the Substructure up to the structural top levels of basement top slabs, and includes all architectural works inside the basement. 
    "地下室" 一般包含基础之上到地下室顶板面标高的所有工作，包括地下室内的建筑工作
  5. "Podium" generally includes all works above the Substructure or Basement up to the structural top level of the podium roof, and includes all architectural works inside the podium and all external wall finishes, roofing, landscaping, parapets and minor structures on the podium roof, but excludes the floor finishes within the footprint of the tower blocks.
    "群房" 一般包含基础或地下室之上到群房顶板结构面标高的所有工作，包括群房内的建筑工作、外墙饰面、屋面层、屋面的绿化、女儿墙及小型构筑物
  6. "Tower" generally includes all works of the tower blocks above the Podium and includes the floor finishes within the footprint of the tower blocks.
    "塔楼" 一般包含群楼之上塔楼的所有工作，包括塔楼脚印以内的楼面饰面
  7. Reinforcement starter bars are generally included in the sections from which they project.
    钢筋的插筋一般归入它们预埋的部位
  8. According to the Standard Method of Measurement of Building Works, the "Plumber" or "Plumbing" trade includes all water supply, rainwater, soil and waste disposal work above ground, while the "Drainlayer" or "Drainage" trade includes all surface water drainage, stormwater and soil and waste drainage underground. Engineers usually call rainwater, soil and waste disposal works above ground as "drainage" as well. To distinguish, the terms "Above-ground drainage" and "Underground drainage" are used. In Bills of Quantities, the Plumber trade is usually given separately under the Basement, Podium and Tower Bills. Since the Drainlayer trade is common to the buildings, it is usual to put it as a separate bill as the Drainage Bill for the underground drainage. Independent surface water channels are usually billed under the Drainage Bill. Surface water channels formed in concrete slabs or roads and paving are usually billed with the concrete slabs or roads and paving as extra over items.
    跟据标准的工程量计算规则, "水管工程"这工种在英语包含地上的给水、排雨水、排污水、排废水的工作，而"渠务工程" 这工种包含地面排水、地下的排雨水、排污水、排废水的工作。工程师通常把地上的排雨水、排污水、排废水的工作亦称为地下的排雨水、排污水、排废水的工作
  9. "Plumbing" according to the Standard Method of Measurement of Building Works includes all water supply, rainwater, soil and waste disposal works above ground.
  10. "External Works" include all works outside the buildings, and may include works outside the site. If the footprint of the basement is larger than the podium, the additional covering on top of the basement top slabs will usually be grouped under the External Works.

Drawings and Specification 图纸及规范

  1. The Drawings and Specification from which the Bills of Quantities are to be measured should be obtained. It is very usual that they are not always provided in full upon commencement of taking-off.
  2. 检查图纸及规范的质量
  3. 商议未齐备图纸的提供时间

    讨论要多少人
    讨论预定工时
  2. Within the allowable time frame, the number of working days or hours to complete the BQ production should be estimated so that the size of the team can be established.
  3. The Works are generally divided into the following groups for measurement by separate people: 
    讨论如何分工：
    • Excavation and structure including reinforcement

  4. The first two items above will be the most time consuming, and should be started as early as possible. For bigger projects, each of these items may be shared by more than one Surveyor.
  5. Non-structural walls and partitions should preferably be measured by the same Surveyor measuring finishes because of his familiarity with the layout and dimensions.
  6. More experienced Surveyors should handle fittings and external works.
  7. A team of 4 Surveyors should be the normal team size for a multi-storey single block of building.
  8. Housing estates with huge podium and extensive external works may need 8 to 10 Surveyors.
