Instrument: North Carolina Flood Field Study: Building Damage Survey Nov 26, 2016

This collection archives instruments and planning materials related to the building damage assessment instrument. The instrument was designed to gather specific types of information on the physical structure of the housing unit itself at the time of the flooding.
The damage assessment survey was designed with three main goals: (1) inspect the general physical condition of buildings (i.e., building type, foundation type, construction type, house dimensions, number of stories, building year, construction quality and maintenance condition), such that a “general damage state assessment” at the building level ranging from 0 to 4 could be provided. The effect of damage state on other engineering and social science parameters could then be calculated; (2) record the high-water mark location observed on the structure or another nearby physical reference point and determine the flood source if possible (i.e., surface flooding, sewer backup, drain pipe); and (3) gather more specific assessments of the external and the internal damage sustained by the structure and its contents to make “detailed (component-based) damage assessment” . In general, flooding without significant flow velocity results in damage to contents and non-structural components in buildings, and Lumberton was no different.

本数据集归档了与建筑损毁评估仪器相关的各类仪器及规划材料。该仪器旨在采集洪水发生时住宅单元自身物理结构的特定类型信息。

本次损毁评估调查设定了三大核心目标：其一，检视建筑的整体物理状态（涵盖建筑类型、基础类型、结构类型、房屋尺寸、楼层数、建造年份、施工质量与维护状况），从而可完成0至4分制的建筑层级“整体损毁状态评估”，后续可据此计算损毁状态对其他工程及社会科学参数的影响；其二，记录在建筑结构或附近其他实体参照点观测到的高水位标记位置，并尽可能确定洪水来源（即地表漫溢、污水倒灌、排水管溢流）；其三，针对建筑结构及其内部物品所遭受的内外损毁开展更具体的评估，以完成“精细化（基于构件的）损毁评估”。

一般而言，无明显流速的洪水会对建筑内物品及非结构构件造成损毁，伦伯顿（Lumberton）地区亦不例外。
