DESCRIPTIONS AND GUIDANCE MANUAL

OF CONSTRUCTION ESTIMATING NORMS – CONSTRUCTION PHASE

Construction estimating norms –Construction Phase (hereinafter referred to as “estimating norms”) means the economic-technical estimates of required quantities of building materials, labors and construction equipment that are employed to complete a construction unit, eg. the required resources for completion of titling of 1 m³ of brick wall, 1 m³ of concrete, 1 m² of floor/wall, 1 tonne of reinforced concrete, 100m of pile length, etc from the construction preparation to the completion of construction (including wastage or losses due to technical work or production process).

The estimating norms are set on the basis of construction regulations and standards; specifications of design-construction-acceptance; levels of mechanization; technical equipment, construction techniques and construction technological advances (new building materials, equipment and state-of –the-art technologies…)

1. Estimated items

The estimating norms include:

- Required quantity of materials: the required quantity of building materials means the quantities of structural materials, auxiliary materials, and components or spare parts, movable materials (excluding auxiliary materials for machineries, construction vehicles and materials whose costs are aggregated into common costs) that are necessary to complete a unit of construction work

The required quantity of building materials herein includes the quantity of material wastage/losses during the construction; for sand in particular, its required volume is inclusive of the dilatancy of sand.

...

The worker rank herein means the average rank of workers completing a unit of construction.

- Required consumption of construction vehicles/equipment/machines: the number of shifts of which construction equipment/machines/vehicles (including auxiliary equipments or machines) is employed to complete a unit of construction.

Table of contents of the estimating norms book

- The estimating norms book is compiled by category, type of work or structure and is uniformly encoded. The estimating norms consist of 11 chapters as follows:

Chapter I: Site preparation

Chapter II: Backfilling and excavation

Chapter III: Pile driving, pressing, pulling and bored pile drilling

Chapter V: Roadworks

Chapter V: Tiling

Chapter VII: Production and installation of pre-cast concrete components

Chapter VIII: Manufacture and installation of wooden components

Chapter IX: Production and installation of steel or iron components

Chapter X: Roofing, ceiling and as-built procedures

Chapter XI: Others

- Tasks, technical requirements, construction requirements and techniques of each estimating norm shall be briefly presented, and the estimating norms shall be measured by a reasonable unit.

- The estimation of each estimating norm is determined as follows:

+The required quantity of primary materials is calculated by their unit.

+The required quantity of auxiliary materials such as materials for scaffolds and others are calculated by the percentage of the auxiliary material cost to its primary material costs.

...

+The required consumption of primary construction vehicles/machines/equipment is calculated by the number of shifts using such vehicles/machines/equipment.

+The required consumption of auxiliary construction vehicle/machines/equipment is calculated by the percentage of their consumption cost to their primary construction vehicles machines/equipment.

Guidance manuals

- The estimating norms are used for cost estimation and is considered as the basis of estimates of construction costs, total investments and cost management.

- In addition to the above mentioned descriptions and guidance manuals, the estimating norms books also provides specific descriptions and guidance manuals on technical requirements, construction conditions and techniques for each category and task.

- For the estimating norms, the height is measured from the elevation of±0.00 to ≤4m; or ≤16m; or ≤50m and from the elevation of ±0.00 to >50m. Construction works whose costs were estimated without height indicator (e.g. plastering, tiling, etc.) when done at the height of over 16 meters, shall include the estimate of resources for conveyance of materials upward...

The classifications of forests, mud, soils and rocks of estimating norms are consistently applied to construction tasks specified in this estimating norms book.
