Foundation Analysis Clause Samples
The Foundation Analysis clause requires a thorough examination and assessment of the building's foundation before construction or renovation begins. This typically involves site inspections, soil testing, and structural evaluations to determine the foundation's suitability for the intended project. By mandating this analysis, the clause helps identify potential issues early, ensuring the safety and stability of the structure and preventing costly problems or delays later in the project.
Foundation Analysis a. Develop recommendations for the foundations and/or bedding of structures, including retaining walls, vaults, storm drains and light poles considering local site conditions and recommended seismic requirements.
b. Prepare technical report.
Foundation Analysis. Depth of foundation The recommended depth for each alternative shall be detailed. A summary table shall be included detailing the structures considered, their depth of embedment Df (m), their lowest N.P.T. and their N.F.C. It shall also include information for minor works such as huts, perimeter fences, as well as (if applicable) other complementary structures such as elevated tanks, cisterns, swimming pools, etc. The type of foundation At least detail the foundation alternatives such as strip foundations, footings, grounds, and also include information for minor works such as huts, perimeter fences, as well as (if applicable) other complementary structures such as elevated tanks, cisterns, swimming pools, etc. Except in exceptional cases, deep foundations should be considered (if required due to soil problems, geological or climatic hazards, or due to load capacity requirements of the projected structures) and other soil improvement techniques or special foundations that may be required. Calculation and analysis of permissible load capacity The corresponding calculation report of the admissible load capacity must be submitted, showing the theoretical basis, sources of information, parameters and numerical values being used, as the case may be, substantiating the criteria for the use of the proposed formulation. The safety factor should be used as established in the applicable standards or their modifications. Alternatives/solutions should be presented for different types of foundations applicable to the projected structures, both main structures (modules, pavilions, etc.) and minor works (perimeter fences, huts, minor buildings), and if applicable, for swimming pools, cisterns, elevated tanks, among others. Settlement Calculation The calculation supporting the estimation of settlements produced by induced pressure shall be presented and the values of the coefficients used and the source of information of the formulations used shall be explicitly stated. The parameters used in the foundation settlement calculations shall be detailed and supported. In cases of problematic soils (e.g. collapsible soils), the allowable capacity must be reformulated either by the use of non-conventional foundations such as grounds, piles, micropiles, among others, or by the need to perform engineering backfilling (controlled backfilling) or to apply soil improvement techniques. For any of the cases, the calculation memory of the admissible capacity of the foundation must be in...
