Project record
Mombasa SEZ DK1 port and jacket quay
Kenya Ports Authority awarded TOA Corporation the civil and building package for the DK1 port at Mombasa Special Economic Zone. The approximately JPY 33.5 billion package includes 2.59 million m3 of dredging, 430,000 m3 of reclamation and a 300 m by 50 m steel-pipe-pile and jacket quay. KPA's December 2025 monitoring report records active foundation dredging and cargo-yard works, but no activity in the turning basin, navigation channel or permanent port facilities that month.

Project anatomy
Contract scope and delivery roles
- Client / authority
- Kenya Ports Authority
- Delivery parties
- TOA Corporation - Package 1 main contractor for civil and building works, Marine dredging, disposal and support-vessel subcontractors - not publicly named by 1 August 2026, Steel-pile, jacket fabrication and installation subcontractors - not publicly named by 1 August 2026
- Contract route
- KPA awarded Package 1: Civil and Building Works to TOA Corporation under the Mombasa Special Economic Zone Development Project port subproject. TOA identifies the employer as KPA, the financing as a JICA Japanese ODA loan using Special Terms for Economic Partnership and the contract value as approximately JPY 33.5 billion. The KPA monitoring report identifies contract KPA/065/2022-23/PDM. The public records do not disclose a separate marine subcontract award.
- Execution window
- TOA's 5 February 2024 award notice states 1,156 days, approximately 38 months, but does not publish a notice-to-proceed date from which an exact completion date can be calculated. KPA's October-December 2025 monitoring reports show active construction, and its project gallery contains environmental monitoring images dated May and June 2026. These records do not establish an accepted progress percentage or revised completion date.
- Works package
- TOA lists 2,590,000 m3 of dredging, 430,000 m3 of reclamation, a 300 m by 50 m quay on steel pipe piles and a jacket structure, 4,470,000 m of prefabricated vertical drains across 14.9 ha, 118,000 m2 of concrete pavement, 2,690 m of drainage and 16 buildings with 11,595 m2 total floor area. TOA describes the trestle and causeway as 214 m by 20 m, while KPA's December monitoring report describes it as 363 m by 20 m and a 13 ha cargo yard. Both official descriptions are retained until the owner or contractor reconciles the package geometry.
- Marine interfaces
- The December report records dredging for the quay foundation and trestle and causeway foundation, with material taken by hopper barge to a designated offshore disposal site. It says a frame-type silt curtain was used and hopper barges were tracked with a Dredging and Dumping Monitoring System. Turbidity and water quality were monitored at 17 locations across Port Reitz and Kilindini, Tudor Creek, the inner reef and the outer reef. The report says no two-week continuous turbidity threshold exceedance occurred, but it does not supply accepted dredging quantities or hydrographic release.
- Commercial evidence boundary
- TOA's approximately JPY 33.5 billion figure is the announced Package 1 contract amount, not a final account, paid value or marine-subcontract price. KPA and TOA have not published separate dredging, disposal, jacket, pile, ground-improvement or building values. JICA is the ODA lender and STEP financing source, not the marine contractor.
