Service Line


At CONEXIG we support clients to fully understand their contractual technical rights and obligations and in dealing with these, the most efficient and effective way. We examine and identify in detail the cause-effect relationship around potential areas of disagreement and isolate them presenting the logics behind potential claims as well as the fact that support them.

Through these analyses we assist clients understanding entitlement and causation and in the quantification of the effects of identified causes. Our multidisciplinary and experienced teams provide invaluable help to clients in presenting, negotiating and resolving their disputed claims in all types of dispute resolution mechanisms including mediation, arbitration, litigation (locally and internationally) and dispute boards before the court. We have had experience related to the international arbitration rules of the International Chamber of Commerce (ICC), AAA, ICDR, CAM Santiago, AMCHAM-SP, CCL Arbitration Center – Lima Chamber of Commerce, Chamber Arbitration and Conciliation Center of Commerce of Bogotá (CCB), CAM-CCBC, CIADI, among others.

Felipe was a party appointed Quantum Expert on many arbitration disputes to settle differences related to EOT impacts and cost overrun related to the construction of a 210mba Brazilian refinery. Amounts disputed were, in average per proceeding, over BRL 250 million. One example includes the Quantum expert appointment by the owner against a Brazilian contractor on the coke plant contract. Matters disputed were presented in an expert report and in an arbitral tribunal. Cross examinations took place from the other party’s counsel and the tribunal itself. The Experts had the opportunity to debate their technical viewpoints through a hot tubbing section. Testimony was made in Sao Paulo (Brazil), in Portuguese, under the CAM-CCBC rules. Under the same refinery project, Felipe was a party appointed Quantum expert on many other disputes resolved under the same venue, law, seat and language.
