SECTION C

DESCRIPTION/SPECS/WORK STATEMENT

C.l General Contractor shall provide all necessary professional engineering services relating to the evaluation and mitigation of natural hazards at specific US Foreign Service Posts designated by the Department of State (DOS), Bureau of Overseas Buildings Operations (OBO). Natural hazards include earthquakes, floods, landslides, and tropical cyclones. Related hazards due to climate change, corrosive environments, sea level rise, tsunamis, and volcanoes may also be included. Engineering services will primarily be in the seismic/structural arena; however, other natural hazards may require professional support from the Contractor from time to time as well.

C.2 Work Statement Structural & Seismic Engineering: The majority of tasks will involve working with existing office and residential buildings to evaluate their seismic adequacy and, where appropriate, perform seismic strengthening concept studies and strengthening designs. In most cases, the need for services stems from new acquisitions of property (i.e. purchases and/or short/long-term leases) or from the need to assess and/or strengthen property already in OBO inventory. Support from the Contractor in conducting seismic peer review of new building designs performed by other A/E firms may also be needed. At the government's option, the Contractor will be required to perform any or all of the below listed tasks for any specific building or portion of a Foreign Service post:

(1) Review all available documentation (drawings, specifications, reports, etc.) for existing building(s) including all recent alterations or modifications, building maintenance surveys, security upgrades, communication center upgrades, etc.

(2) Travel to posts to perform tasks such as, but not limited to the following:

a) investigate/evaluate as-built conditions and configurations, earthquake damage, structural condition, foundation settlement, and geological hazards from past earthquakes;

b) perform and/or supervise sampling and testing (destructive and/or non-destructive) of materials such as infilled masonry, bearing wall masonry, concrete, steel, and rebar;

c) perform structural surveys and document structural features for buildings with or without structural drawings;

d) interview local structural engineers and construction contractors to determine local seismic design and construction practices (code requirements and actual practice) for residential construction in a Post’s inventory;

e) visit new residential construction sites to observe means and methods of construction, materials, and quality control;

f) report on local residential types of construction (building type, combinations of building types, or unique types – per ASCE 41), and summarize the historical and expected seismic performance of predominant building types;

(3) Perform seismic evaluation of structure(s) per level of detail defined by OBO, typically from one of four possible levels of effort: a) inventory (i.e. sidewalk/visual screening); b) inventory-plus (i.e. walk-through qualitative assessment and determination of potential building performance based on historical knowledge and professional experience); c) limited detailed assessment (i.e. involves limited engineering calculations based on existing drawings only); and, d) detailed assessment involving detailed engineering investigation and analysis. The American Society of Civil Engineers Standard Seismic Evaluation and Retrofit of Existing Buildings (ASCE 41) is often times used as a basis or starting point for the above evaluations. The International Existing Building Code may also be used if applicable. The detailed assessments might include a linear static analysis, linear dynamic analysis, and/or a push over type of analysis - the goal being to determine behaviorally, the probable performance (i.e. sequence of failure/collapse mechanisms) that might develop during an actual event.

(4) Present and categorize conclusions regarding anticipated performance and any corrective actions required within context of the following qualitative Seismic Hazard Rating (SHR) scale: Minor damage (good performance); Moderate damage (fair performance); Major damage (poor performance); Partial/total collapse (very poor performance). Also, indicate any need for immediate major strengthening.

(5) Address in a broad perspective, non-structural elements and major equipment support anchorages, lateral bracing, and tie downs.

(6) Prepare reports for the above evaluations including photographs, logs of field data collected, interviews, sketches, drawings, and analysis calculations.

(7) Provide an update of local seismicity. This could include a specific task for a limited seismicity update for a specified site or for a property/site purchase.

(8) Develop conceptual/developmental/final designs (A/E Services) for the seismic strengthening of a specific building as directed by OBO. Designs shall be based on the OBO Building Code, the International Building Code (IBC), the American Society of Civil Engineers Standard Seismic Evaluation and Retrofit of Existing Buildings (ASCE 41), the International Existing Building Code (IEBC), and other standards as directed by OBO. Retrofit of existing buildings is typically required to meet a life safety structural performance level (or higher if specified by OBO for a specific tasking). Conceptual design effort includes evaluating several alternatives to the recommended scheme usually to a criterion of minimum cost and least disruption to occupants and operations. For final designs, serve as prime professional of record for the contract documents – drawings and specifications. As requested, assist OBO in Construction Administrative Services to include review of submittals, response to RFIs, evaluating field test reports, etc.

(9) Include plans for continued post operations, swing space requirements, and stages for phased construction for the recommended scheme, as well as alternatives. Develop complete construction documents for the seismic strengthening scheme selected by OBO including all changes required to the architectural, civil, structural, mechanical, electrical, plumbing and security building systems.

(10) Identify collateral building system changes along with any potential modifications to the existing foundation system.

(11) Provide preliminary cost/final estimates, based on Washington, DC costs.

Other Natural Hazards – Floods, Landslides, Tropical Cyclones:

(12) Tasks will require engineering support to OBO’s Natural Hazards Program to evaluate sites prone to:

· flooding to include drainage and specification of remedial measures for flood protection;

· landslide or settlement problems to include review of geotechnical reports and site boring logs for evaluating and stabilizing earth retaining structures or building underpinning;

· tropical cyclones or high wind regions to include protection of buildings and personnel from windborne debris and water damage from storm events.

Engineering studies may also be required for related natural hazards including climate change, corrosive environments, sea level rise, tsunamis, and volcanoes.

Other Tasks

(13) Emergency Response: If directed by the Contracting Officer, travel to a Foreign Service Post damaged by an earthquake or other natural disaster. Assist OBO staff and/or post personnel with regards to post-earthquake (or natural disaster) occupancy needs including all or any combination of the following:

a) investigation of damaged buildings for life safety concerns, re-entry, and continued occupancy; design of shoring and stabilization measures;

b) investigation of site geo-technical hazards;

c) assistance in critiquing owner's engineer's repairs and short term solutions;

d) expert opinion and advice, especially regarding adjacency issues and neighboring life safety threats; etc.

Mobilization time may be required in as short as 24 hours depending upon the severity of the damage, mobilization of the OBO Disaster Response Committee, availability of air travel; etc.

(14) New Acquisitions: Evaluate properties proposed for acquisition by the US Government with regard to the structural adequacy for intended uses as described in preceding sections. Additionally and when specifically directed by OBO, include investigation/analysis of gravity load capacity and wind resistance in conjunction with seismic lateral analysis.

(15) NH Database Support: Assist OBO in developing and maintaining database(s) for natural hazards risks (earthquakes, tropical storms, wind, geohazards, floods, tsunamis, etc.) to personnel, property, and structures at Foreign Service posts worldwide.

(16) Presentations: When directed, travel to Washington D.C. to personally present and review report findings and recommendations with appropriate OBO officials. Develop appropriate presentation (PowerPoint, handouts, etc.) to support briefing of senior level DOS personnel.

(17) Man-Hour Support: Provide for dedication of man-hours for miscellaneous consultant services in earthquake engineering and natural hazards, serving as an extension of OBO staff for quick response/turn-around and expert opinion in the development, review, and oversight of normal work products such as assessments, reports, studies, database management, presentations, website content development, etc.
