§ 5.3.6. Seismic Hazards Identification Program.

§ 5.3.6.1. Purpose.

It is found that in the event of a strong or moderate local earthquake, loss of life or serious injury may result from damage to or collapse of buildings in the City of Fairfield. It is generally acknowledged that Fairfield will experience earthquakes in the future due to its proximity to both the San Andreas and Hayward faults. The purpose of this ordinance is to promote public safety by identifying those buildings in Fairfield which exhibit structural deficiencies and by accurately determining the severity and extent of those deficiencies in relation to their potential for causing loss of life or injury. The City Council finds it desirable to identify the hazards that these deficiencies may pose to occupants of buildings and pedestrians in the event of an earthquake. Such a seismic hazards identification program is consistent with the state’s unreinforced masonry law of 1986.

§ 5.3.6.4. Engineering Reports.

(A) Preparation of reports. Each owner of a building described in section 5.3.6.3(A) shall retain a civil or structural engineer to prepare the investigation and engineering report described in this section.

(B) Purpose. The purpose of the engineering report is to investigate, in a thorough and unambiguous fashion, a building’s structural systems which resist the forces imposed by earthquakes and to determine if any individual portion or combination of these systems is inadequate to prevent a structural failure (collapse or partial collapse).

(C) General. Each building shall be treated as an individual case without prejudice or comparison to a similar type or aged building that may have greater or lesser earthquake resistance. Generalities or stereotypes are to be avoided in the evaluation process by focusing on the specifics of the structural system of the building in question and the local geology of the land on which the building is constructed.

(D) Level of Investigation. Some buildings will require extensive testing and field investigation to uncover potential structural deficiencies, while others will allow the same level of overall evaluation by a less complicated process due to the simplicity of design or availability of original or subsequent alteration design and construction documents.

It is the responsibility of the engineer performing the evaluation to choose the appropriate level of investigation which will produce a report that is complete and can serve as a sound basis for a conclusion on the collapse hazard the building may present.

(E) Format for the Report. The following is a basic outline of the format each engineering report should follow. This outline is not to be construed to be a constraint on the professional preparing the report, but rather to provide a skeleton framework within which individual approaches to assembling the information required by the ordinance may be accomplished. It also will serve as a means for the city to evaluate the completeness of each report.

General Information. A description of the building that includes:

(1) The street address.

(2) The type of occupancy use with the building.

(3) A plan showing the square footage of each use.

(4) A plan showing the location, type, and extent of lateral force resisting elements in the building, horizontal & vertical.

(5) The date of original and any subsequent additions, or structural alterations of the building.

(6) The name and address of the original designer and contractor, if known, for item (5).

Investigation and Evaluation of Structural Systems. All items to be investigated and the methods of investigation for each type of building under consideration are available from the city’s building inspection department.

(F) Test Reports. All field and laboratory test results shall be included in the report. Evaluation of the significance of these test results shall be made with regard to each structural system or typical connection being evaluated. This evaluation may be limited to a statement of the adequacy or inadequacy of the system or connection based on the lateral load demand it would be required to resist by calculation. If tests reveal inadequacy, a conceptual solution must be included in the report.

(G) Conclusion. Based on the specific evaluation items, a statement shall be provided explaining the overall significance of the deficiencies found to exist in the building’s lateral force resisting systems regarding potential collapse or partial collapse failure.

Recommendations. An appropriate solution, which could be used to strengthen the structure to alleviate any collapse or partial collapse threat, shall be specified.

(H) Exceptions and Alternatives. Exceptions to the specific items required to be included in an engineering report may be granted by the Building Official upon review of a written request from the engineer preparing the report. Such a request shall provide evidence that adequate information concerning the required item(s) can be determined by alternate means or that a conclusion can be made about the item(s) without following the solution called for in the appropriate section. The purpose of granting such exceptions shall be to reduce the cost or disruption that would result from taking required actions when it can be shown that they are unnecessary to provide information available by other equivalent means. In no case will an exception be granted which would result in an item not being completely evaluated. The decision of the building official in granting an exception is final.

(I) Reports for buildings in category I of section 5.3.6.3 shall be submitted within one and one-half (1-1/2) years of receiving notice pursuant to section 5.3.6.3. Reports for buildings in category II of section 5.3.6.3 shall be submitted within two (2) years of receiving notice pursuant to section 5.3.6.3. Reports for buildings in category III of section 5.3.6.3 shall be submitted within two and one-half (2-1/2) years of receiving the notice pursuant to section 5.3.6.3.

§ 5.3.6.5. Review of Reports.

a) The city may utilize the services of structural or civil engineers to assist the building official in determining if the submitted engineering reports conform to the requirements of this ordinance.

b) The cost of this review shall be recovered by a fee assessed from the building owner based on the time required for the review. This fee will be deducted from the plan review fee collected for any future construction work that deals directly with correcting any of the structural inadequacies specified in the engineering report.

c) Copies of the engineering reports shall be available to any interested individuals for a standard copying fee or may be reviewed in the building inspection department’s offices.
