Therefore, a risk management methodology based on the likelihood of the occurrence of certain events and their economic consequences is proposed, which is applicable to bored piles (Kelly drilled) in coarse soils, easy to use, and simple to implement since the initial stage of construction. Of 12 case studies of construction works involving bored piles (Kelly drilled) carried out in Luanda (Angola), two selected examples involving the proposed risk methodology on sandy soil layers with interbedded clays are discussed. Subsequently, whether the overall foundation contract budget is affected by assessed risk is determined, and what influence it has on the budget in the light of mitigating factors and associated real costs. This method intended to encourage the adaptation of sustainable risk management in bored piles construction by the site project managers, involving risk analysis concurrently with budgetary review. Though the level of assessed technical risk may be acceptable, overall costs associated with the contract in question may not be acceptable.<\/jats:p>","DOI":"10.3390\/infrastructures6050077","type":"journal-article","created":{"date-parts":[[2021,5,20]],"date-time":"2021-05-20T06:13:45Z","timestamp":1621491225000},"page":"77","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Risk Management of Bored Piling Construction on Sandy Soils with Real-Time Cost Control"],"prefix":"10.3390","volume":"6","author":[{"given":"Pedro","family":"Mata","sequence":"first","affiliation":[{"name":"GeoBioTec, Department of Earth Sciences, NOVA School of Science and Technology, FCT Nova, NOVA University of Lisbon, Campus de Caparica, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5900-3885","authenticated-orcid":false,"given":"Paula F.","family":"Silva","sequence":"additional","affiliation":[{"name":"GeoBioTec, Department of Earth Sciences, NOVA School of Science and Technology, FCT Nova, NOVA University of Lisbon, Campus de Caparica, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0344-1867","authenticated-orcid":false,"given":"Fernando F.
