The core scope of work and statement of work for this tender (Consultation No. 74260102) pertains to an framework agreement for intellectual services focused on environmental, regulatory, and technical studies for the maintenance and modernization of pleasure ports within the Aix-Marseille-Provence Metropolis.

Specifically, Lot 1, titled "Inspections subaquatiques et bathymétriques, relevés biocénoses, campagne d’analyse et suivi environnemental," encompasses the following key missions and deliverables:

• MISSION 1: Diagnostics of maritime structures through subaquatic inspection with expertise. This involves detailed inspection reports, utilizing qualified divers for examining structures such as concrete/stone quays, quays on piles, and dikes, including material setup and removal on site.
• MISSION 2: Biocenosis surveys at a site via subaquatic inspection. This requires reports on marine biocenosis, performed by a diving team specialized in marine ecology, involving representative transects for specific water surface areas.
• MISSION 3: Environmental monitoring services for a construction site, including physico-chemical water parameter measurements. This involves daily environmental monitoring and turbidity measurements, with a daily register and weekly reports summarizing events and turbidity data.
• MISSION 4: Bathymetric campaigns of ports or their surroundings, for water surfaces up to 5,000 m². Deliverables include bathymetric reports and mapping.
• MISSION 5: Sedimentology campaigns and various measurements of sediments and water. This includes collecting and analyzing average sediment samples (from immersed sediments and terrestrial materials for beach characterization) and water samples for physico-chemical characterization. Parameters analyzed include heavy metals (Lead, Nickel, Copper, Hexavalent Chromium, Zinc, Tin), Iron, Aluminum, TBT, total Pesticides, MES, DCO, METOX, and total Hydrocarbons. Reports can include "porté à connaissance" based on decennial dredging decrees for sediment disposal or deposition on beaches, and simplified interpretation reports.
• MISSION 6: Illustrations. This involves creating four illustrations per project, comprising a close-up front view, a side view, a rear view, and a distant view to assess environmental integration.

All deliverables are expected to adhere to the prescriptions of the CCTP (Cahier des Clauses Techniques Particulières).
