Probabilistic Tsunami Amplitudes and Source Disaggregation for Selected At-Risk OBO Diplomatic Posts

STATEMENT OF WORK

Period of Performance: 1 November 2020 – 31 July 2021

Place of Performance: Non NOAA Site

Introduction and Background The Bureau of Overseas Buildings Operations (OBO) at the Department of States (DoS) has requested the NOAA Center for Tsunami Research (NCTR) of the Pacific Marine Environmental Laboratory, NOAA to conduct a comprehensive tsunami hazard assessment study for selected DoS overseas posts. The DoS Properties at posts may be either owned or leased, and include occupancy types such as office buildings, representational spaces, and staff-level residences. The largest portion of many posts’ building inventories tends to be staff-level residences leased within buildings available on the local market in areas that surround a central compound.

NCTR will develop the tsunami design zone maps considering a 2,500-yr tsunami return period in compliance with the American Society of Civil Engineering (ASCE 7-16) and the modifications added for the ASCE 7-22 standards for selected DoS posts.

Scope of Work The award recipient shall develop the 2,500-yr maximum offshore tsunami amplitudes and predominant wave periods along the 100-m depth contour and source disaggregation based on the method of Probabilistic Tsunami Hazard Assessment (PTHA) for each of the six (6) DoS posts listed in Table 1. The PTHA offshore amplitudes and source disaggregation shall be compliant with the ASCE 7-16 standard and the modifications made for ASCE 7-22.

Table 1. Name and GPS coordinates of the six (6) DoS posts that the award recipient will develop PTHA offshore amplitudes and wave periods and will provide source disaggregation for.

Locations represent either existing post compound sites, or proposed new sites. Refer to Attachment A for aerial maps showing geographical boundaries in which these sites are located as well as other properties managed by the posts (e.g. residential, etc). Studies conducted and results provided will include a coastal length sufficient to capture potential tsunami risks posed to properties within these boundaries that is required by the ASCE 7-16 and 7-22 standards.

Requirements Experience in the development of offshore tsunami amplitudes and wave periods and source disaggregation using the ASCE 7-16 Probabilistic Tsunami Hazard Assessment method.
