Kenya’s ambition to strengthen its position as a destination for international conferences and large-scale business events is taking physical form at Bomas of Kenya in Nairobi. Construction of the Bomas International Convention Complex (BICC) represents one of the country’s most ambitious investments in specialised public building infrastructure, combining large assembly spaces, exhibition and meeting facilities, hospitality components and supporting infrastructure.
The development is intended to expand Kenya’s capacity to host international conferences, diplomatic gatherings, exhibitions, corporate events and other large assemblies. Its proposed capacity of approximately 11,000 people places it among the country’s largest planned convention facilities.
For the engineering and construction industry, however, the significance of the project extends beyond its intended tourism and commercial benefits. It presents a substantial undertaking involving architectural planning, structural engineering, mechanical and electrical installations, specialised building systems, site infrastructure and the coordination of several government institutions.
The project has also attracted attention because of its procurement history, changes in the contracting arrangements, substantial financing requirements and questions raised by the Auditor-General.
Understanding the BICC requires examining both the engineering behind the buildings and the institutional and financial arrangements through which the development is being delivered.
Designing for large-scale conferences
The BICC is being developed as a multi-facility convention and events destination at the existing Bomas of Kenya site along Lang’ata Road.
Government descriptions have referred to a development covering approximately 100,320 square metres, although other published descriptions give a larger figure for the wider development. The distinction between the main building footprint, the first development phase and the eventual master-plan area needs to be established from the approved drawings.
The main convention facility is designed around a reported combined capacity of approximately 11,000 people. Its principal spaces include a 5,000-seat convention hall, a 3,500-seat auditorium, a ballroom and numerous smaller meeting rooms.
The latest descriptions by Bomas management refer to 35 meeting rooms, although earlier project descriptions referred to more than 20. The reported ballroom capacity has also varied between 2,500 and 15,000, making the approved room schedule an important document for confirming the final configuration.
The different spaces are intended to support events of varying sizes, from international plenary conferences and exhibitions to smaller technical meetings, diplomatic engagements and corporate functions.
This places particular demands on the architectural design. Unlike conventional office buildings, convention centres must accommodate large numbers of people arriving and leaving within relatively short periods. They also require flexible internal arrangements that allow spaces to be adapted for different event formats.
The design must coordinate public entrances, registration areas, circulation corridors, exhibition spaces, service access, catering facilities and emergency exits. It must also provide adequate separation between public areas and operational spaces used by event organisers, security personnel and technical teams.
Crowd management is especially important in a facility accommodating thousands of occupants. The width and distribution of escape routes, travel distances, exit capacities, emergency lighting, fire compartmentation and access for firefighting services must be considered together rather than as separate installations.
The architectural concept must consequently balance the visual identity of a major international venue with the practical requirements of safety, accessibility, flexibility and efficient operation.
The structural engineering challenge
Large convention halls present a significant structural engineering challenge because they require extensive unobstructed floor areas.
In an exhibition hall or auditorium, internal columns can interfere with seating arrangements, stage visibility, temporary installations and the movement of equipment. The structural design must therefore provide sufficient roof spans and load-carrying capacity while limiting the need for internal supports.
The BICC construction has featured extensive concrete structural works and a substantial roof installation. Progress reports have identified roof panels, purlins and associated structural works among the activities undertaken during construction.
The engineering of such a roof requires careful consideration of its structural framing, supporting columns, connections and foundations.
The design must account for the self-weight of the roof, roofing materials, suspended services, maintenance loads and wind actions. Deflection and structural movement must also remain within acceptable limits to protect roof finishes, drainage systems, suspended ceilings and building services.
The construction sequence is equally important. Large roof components must be fabricated, transported, lifted and assembled in a controlled manner. Temporary stability during erection is a critical consideration, particularly where substantial structural elements are being installed at height.
The design and installation of roof connections require quality control through appropriate material verification, fabrication inspections, dimensional checks and installation records.
Foundations provide the final link in the structural load path. Their design depends on ground conditions, building geometry and the loads transferred from the superstructure. Geotechnical investigations are therefore essential in determining suitable foundation arrangements and identifying potential ground-related construction challenges.
Publicly available material does not provide sufficient detail to establish the exact roof structural system, maximum spans, steel specifications, connection design or foundation configuration used at BICC. These should be confirmed through the approved structural drawings and the contractor’s engineering documentation.
Nevertheless, the construction illustrates the level of structural coordination required in buildings designed to accommodate large gatherings without compromising the flexibility of their internal spaces.
Building services: The systems behind the convention experience
A convention centre’s performance depends heavily on the quality and reliability of its mechanical, electrical, plumbing and ICT systems.
These installations must support thousands of occupants, large-scale lighting and audio-visual equipment, catering operations, communications infrastructure and specialised event requirements.
Electrical demand is particularly important. The facility will require power for general lighting, stage equipment, exhibition installations, lifts, escalators, kitchen equipment, air-conditioning, security systems and communications networks.
The electrical distribution design must provide adequate capacity, protection and reliability. Critical systems require appropriate standby arrangements to maintain essential operations during interruptions to the main electricity supply.
Reports on the BICC development have referred to solar generation and standby power infrastructure. The final installed solar capacity, expected contribution to electricity demand, generator capacity and grid connection arrangements require confirmation.
Air-conditioning and ventilation are equally important. Large auditoriums and convention halls can experience significant variations in occupancy, resulting in changing cooling and ventilation requirements.
The mechanical design must maintain acceptable indoor air quality, temperature and humidity while responding efficiently to different occupancy levels. Separate operational zones can allow individual halls and meeting rooms to be conditioned according to actual use rather than operating the entire complex at full capacity.
Acoustic engineering is another specialised requirement. Convention facilities must support intelligible speech, presentations, live performances and simultaneous events. The auditorium, main hall and smaller meeting rooms require appropriate sound distribution and acoustic separation.
Wall and ceiling finishes, room geometry, sound-absorbing materials and the positioning of loudspeakers all influence acoustic performance. Mechanical equipment must also be selected and installed to minimise unwanted noise and vibration.
Fire safety requires an integrated approach involving detection, alarm systems, suppression equipment, emergency exits, smoke management and firefighting access. These systems must be designed around the building’s occupancy, layout and applicable safety requirements.
ICT infrastructure will also be central to the complex’s ability to attract international events. Modern conferences increasingly depend on reliable high-speed connectivity, digital registration, simultaneous interpretation, video conferencing, access control and integrated audio-visual systems.
The challenge for the engineering teams is to coordinate these installations with the architecture and structural works. Ductwork, cable trays, pipes, plant rooms and maintenance access must be accommodated without compromising the building’s structural integrity or usable space.
Supporting infrastructure and site development
The BICC development extends beyond the principal convention buildings. Its performance will also depend on the supporting infrastructure serving the site.
Road access, parking, pedestrian circulation, water supply, sewerage, stormwater drainage, electricity distribution and emergency access all contribute to the functionality of the completed development.
A facility accommodating thousands of people can generate substantial traffic, particularly when major conferences begin and end at similar times.
Site planning must provide for vehicle entry and exit, pedestrian safety, service vehicles, public transport connections and emergency response. The relationship between the complex and surrounding roads is particularly important given its location along the Lang’ata transport corridor.
Stormwater management also requires careful attention. Extensive roof areas and paved surfaces increase runoff volumes during heavy rainfall. Drainage systems must be designed to manage these flows while limiting flooding, erosion and damage to surrounding infrastructure.
Water supply and wastewater arrangements must accommodate peak occupancy, including the demands of sanitation facilities, kitchens, cleaning operations and hospitality services.
The BICC has also been associated with additional electricity infrastructure and improvements to site access, including the Bomas Ring Road. These works are important because the operational capacity of the convention buildings depends on the reliability of the wider infrastructure network.
The project therefore needs to be evaluated as an integrated development rather than as an isolated building construction exercise.
CRBC and the transition in project delivery
The current construction arrangement followed an earlier procurement process involving Turkey’s Summa Turizm Yatirimciligi Anonim Sirketi.
In November 2023, Summa was awarded the original tender to design, build and equip the convention complex at a proposed cost of approximately US$245 million, equivalent to about KSh31.7 billion at the time.
The procurement was subsequently terminated by the Ministry of Defence, which cited significant changes in the scope of works and the applicable financing model.
The dispute was considered by the Public Procurement Administrative Review Board. In its December 2024 decision, the Board found that the termination had occurred 329 days after the tender award and ruled that the procurement process had been terminated irregularly. The Board directed the procuring entity to proceed with the process.
The earlier procurement did not become the construction contract now being implemented.
A new contract was subsequently entered into with a foreign contractor on 18 March 2025. The Auditor-General’s report identifies the contract value and implementation period, while subsequent reporting identifies China Road and Bridge Corporation (CRBC) as the contractor.
The current contract is valued at US$324.09 million, equivalent to approximately KSh41.9 billion, with a contractual period of 24 months.
The contract covers the design, construction and equipping of the complex.
A design-and-build arrangement can provide advantages in coordinating engineering design, construction methods, procurement and programme management. It also places considerable responsibility on the contractor to coordinate specialist consultants, suppliers and subcontractors.
For a development of this complexity, coordination must extend across architectural design, civil and structural engineering, mechanical and electrical installations, fire protection, ICT, specialist finishes and external infrastructure.
The client must retain effective oversight through design reviews, inspections, quality assurance and verification of completed works.
The construction process should also provide a clear record of material approvals, fabrication inspections, testing, commissioning and statutory compliance.
The identity of the lead architectural practice and the specialist engineering consultants has not been established conclusively from the publicly available contract and project information reviewed for this feature. Their disclosure would help the industry understand the professional teams responsible for the design and technical delivery.
Who is implementing the project?
The institutional arrangement is another important feature of the BICC development.
The Ministry of Defence was assigned procurement and implementation responsibilities, with the Kenya Defence Forces providing engineering oversight and construction capacity.
The Ministry of Tourism retains responsibility for the project’s tourism positioning, while Bomas of Kenya is expected to play a central role in the eventual operation of the facility.
This division of responsibilities was brought into focus during Senate scrutiny in September 2026.
Tourism Cabinet Secretary Rebecca Miano informed the Senate Committee on Roads, Transportation and Infrastructure that the Ministry of Defence held the principal construction and procurement documentation, having been delegated responsibility for implementing the project.
The Ministry of Tourism, meanwhile, was responsible for monitoring progress from the tourism and ownership perspective and preparing for the facility’s eventual use.
Senators sought access to the construction contract, financing agreements, procurement records, approved designs, bills of quantities, payment records and progress reports.
The questions raised by the committee highlight the importance of clear accountability where one government institution manages procurement and construction while another is responsible for the funding and eventual operation of the completed asset.
The participation of military engineers in civilian infrastructure delivery also provides an opportunity to examine the respective responsibilities of the engineering teams, the main contractor, the client and independent professional consultants.
Technical supervision, contractual administration, quality assurance and statutory approvals must be clearly documented regardless of the institutional structure adopted.
The identities of the lead consultants, specialist subcontractors and Kenyan firms participating in the project should form part of the project’s publicly accessible technical record.
The investment: A KSh41.9 billion construction contract
The financial arrangements are among the most closely scrutinised aspects of the BICC development.
The earlier Summa proposal was approximately US$245 million, or KSh31.7 billion. The current CRBC contract is worth US$324.09 million, equivalent to approximately KSh41.9 billion.
The difference is substantial, but the two figures should not automatically be interpreted as evidence of a direct cost overrun.
The Public Procurement Administrative Review Board recorded that the earlier procurement was terminated following changes in the project scope and financing model. A proper financial comparison would therefore require the original and revised designs, bills of quantities, contract conditions and details of the additional facilities included in the current development.
Some subsequent reports have referred to an overall project cost of approximately KSh45.1 billion, while other reporting has used figures closer to KSh31.5 billion. The distinction between the main construction contract, associated infrastructure, hospitality components and the wider development budget needs to be clarified.
The financing arrangements have also evolved.
The Auditor-General’s report for the year ended 30 June 2025 records that the Ministry of Defence received cumulative disbursements of KSh1.73 billion from the State Department for Culture, Arts and Heritage. At that point, KSh1.45 billion had been paid towards the contractor’s advance payment.
The report also identified a discrepancy between the contract’s repayment arrangements and the financing plan approved by the National Treasury.
The contract provided for nine instalments over 24 months, while the Treasury-approved financing arrangement provided for a ten-year deferred payment period.
This difference raises important questions about how the government’s contractual obligations are being financed and the extent of its long-term exposure.
In September 2026, the Senate was also informed that the project was funded through the Tourism Fund, prompting further questions about the relationship between the funding institution, the Ministry of Defence and the Ministry of Tourism.
Earlier financing discussions had also involved a proposed arrangement with the African Export-Import Bank (Afreximbank). However, the precise relationship between that proposal and the financing of the current CRBC contract requires confirmation from the underlying agreements.
For a public infrastructure investment of this magnitude, the relevant information should include the identity of the borrower, the financing institution, repayment period, interest and other financing charges, government guarantees and the ultimate source of repayment.
The financial structure is important because the economic benefits of a convention centre may take several years to materialise. Its ability to sustain operations will depend on event bookings, utilisation rates, operating expenditure and the cost of maintaining specialised building systems.
What the Auditor-General found
The Auditor-General’s report on the Ministry of Defence for the financial year ended 30 June 2025 raised several concerns about the procurement and financing arrangements for BICC.
One observation concerned the timing of approval for direct procurement. The Accounting Officer approved the request for authority on 17 February 2025, while procurement proceedings had already commenced, as evidenced by tender invitation documents and a site visit certificate dated 13 and 14 February 2025.
The Auditor-General identified this as contrary to Section 69(2) of the Public Procurement and Asset Disposal Act, 2015, which addresses retrospective procurement approvals.
The report also identified the inconsistency between the contract’s nine-instalment repayment plan and the ten-year deferred payment arrangement approved by the National Treasury.
Another concern was the absence of development budget allocations for the project in the State Department for Culture, Arts and Heritage budget for the 2024/2025 financial year.
The report further recorded that the project progress report dated 2 July 2025 indicated 12.9 per cent completion, while payment towards the advance stood at 3.46 per cent of the contract value.
The Auditor-General warned that delays in payment could expose the government to penalties and additional charges.
These findings concern procurement compliance, financial management and contractual administration. They should not be interpreted as proof of structural defects or poor construction quality.
However, they demonstrate why effective financial oversight and project administration are essential to delivering major infrastructure within the agreed cost and programme.
For the engineering profession, access to the approved designs, technical reports, bills of quantities and subsequent progress assessments would provide a more complete basis for evaluating the project.
Construction progress and the delivery programme
Construction began in March 2025 under the current implementation arrangement.
Progress reporting has produced different completion figures because some assessments refer to the main convention building while others cover the wider development.
A government inspection reported in July 2026 placed the main convention centre at 86.21 per cent completion, while Phase One of the overall project stood at 43.66 per cent.
A separate Business Daily report in September cited 38 per cent overall completion as at June 2026, against a target of full completion for the 2025/2026 financial year.
The government inspection identified ongoing works involving roof panels, purlins, curtain walls and air-conditioning ducts. These activities illustrate the transition from the principal structural works towards building enclosure, internal installations and finishing.
The contractual period recorded by the Auditor-General was 24 months from March 2025. Subsequent government and media reporting has referred to 31 December 2026 as the revised construction completion target.
The distinction between completion of the main convention building, completion of Phase One, testing and commissioning, and readiness for public operation is important. A building may be structurally complete while substantial work remains on its services, finishes, external infrastructure and statutory approvals.
For a facility of this scale, commissioning should include functional testing of electrical installations, standby power, air-conditioning, fire protection, lifts, security, communications and integrated building management systems.
The eventual handover should also include operating manuals, maintenance schedules, equipment warranties, asset registers and training for the facility’s technical personnel.
Beyond construction: The challenge of operating a major convention centre
The completion of BICC will mark the beginning of another demanding phase: operating and maintaining the facility.
Convention centres are capital-intensive assets. Their buildings and equipment require continuous maintenance, specialist technical personnel and planned replacement of components throughout their operating lives.
The roof structure, façade, waterproofing systems, air-conditioning plant, electrical installations, lifts, fire protection equipment and ICT infrastructure will all require scheduled inspection and maintenance.
A comprehensive facilities management strategy should be developed before handover. This should include asset registers, equipment manuals, commissioning records, maintenance schedules, warranties, spare-parts arrangements and staff training.
Energy consumption will also be a major operating consideration. Air-conditioning, lighting and event equipment can account for substantial electricity demand, particularly when the complex is hosting large gatherings.
Building management systems can help monitor energy use, regulate environmental conditions and identify equipment faults. Proper zoning of air-conditioning and lighting systems can also allow individual halls and meeting rooms to operate according to actual occupancy.
Water efficiency, waste management and the responsible procurement of maintenance materials will contribute to the facility’s long-term environmental performance.
The commercial model must similarly account for maintenance and periodic refurbishment. A facility that attracts major international events but lacks adequate resources for maintenance risks losing its competitive position over time.
Its success will depend on competitive event pricing, reliable technical services, accessibility, hospitality provision and the ability to attract repeat business.
A major test of Kenya’s infrastructure delivery capacity
The Bomas International Convention Complex represents an ambitious investment in Kenya’s tourism, hospitality and business-events infrastructure.
Its successful delivery will require more than completing the buildings within the construction programme. Structural integrity, building-services performance, safety, accessibility, operational efficiency and long-term maintainability will determine whether the development achieves its intended purpose.
The project also presents an opportunity to demonstrate how government institutions, military engineering capacity, international contractors and Kenyan professionals can work together on complex public infrastructure.
For the construction industry, the lessons will extend beyond the Bomas site. The project raises questions about design-and-build procurement, professional accountability, financing arrangements, independent supervision, local participation and the management of public assets throughout their lifecycle.
Ultimately, the value of the complex will not be measured by its size or construction cost alone. It will be determined by the quality of the infrastructure delivered, its ability to attract and host major events, the economic activity it generates and the government’s capacity to maintain it over the coming decades.
The engineering ambition is substantial. The real test will be delivering a facility that performs as designed, remains financially sustainable and provides lasting value to the country.
