Project development, Design, Build & Maintenance (DBM) and other construction sites will suffer in various ways from the Corona crisis. The sector expects lengthy legal proceedings about: yes then no force majeure or unforeseen circumstances, the influence of the new protective measures from the government, the right to extension of the time for completion and/or financial compensation, good faith, etc. Such discussions do not reflect well on relationships on the construction site and unnecessarily paralyze the treasury and financial planning of parties.
