UPGRADING TO BITUMEN STANDARD OF AKOBWAIT - BENGA - PAPA PRIMARY SCHOOL ROAD10m Concrete Bridge Single span Reinforced Concrete Bridge of 10m in length and 10.6m width. The bridge had 4No. main beams and 3No. cross beams at the abutments and at mid- span. The foundations for the bridge was pad footings embedded on rock. Upgrading 3km road to Bitumen Standards.The main scope was upgrading the gravel road to bitumen standards. The road composed of subgrade material fill layers, cement improved gravel base and 2 layers of surface dressing with 14/20 and 10/14 pre coated chippings as 1st and 2nd seal respectively.My roles and responsibilities included.• Assist in detail setting out of the entire road section (3KM) and marking of the centerline and right of way. • Preparation of the Programme of Works for the entire road and bridge.• Drafting of the work methodology for the construction of the road and bridge.• Preparation of the bar bending schedule from the drawings provided for approval.• Liaising with the RE’S team on issues and matters concerning the project• Supervision of construction of the entire bridge and ensuring all the required standards and specifications are adhered to.• Ensuring that all Rebars were tied and at their correct position• Monitored and enforced safety protocols on-site.• Managed subcontractors involved in construction activities.• Provided regular updates on project milestones and challenges.• Assisted in monitoring project costs and expenses.• Overall management of the site.

THE NAIROBI EXPRESSWAY PROJECT.- Construction of Interchanges at Capital Center, Haile Selassie, Museum Hill, Westlands, James Gichuru Mlolongo, SGR, JKIA, Eastern Bypass and Southern Bypass.- Construction of various Toll Stations along the entire road section. Precast of Box girders, Pier shafts, Peir Caps, Retaining wall Blocks, Road Kerbs, Crash Barriers among others.- The precast box girders were of four types with different lengths between 27m to 33m depending on the skew angle of the box girder (< 15°, =15°, >15° - <30°, =30°). Selected bridges had pile foundations while others had pad footing foundations embedded on rock. The box girders were placed into position span by span using crawler cranes and gantry cranes.My roles and Responsibilities included;• Supervision of construction of all interchanges, bridges and retaining walls along the Right of Way.• Ensuring that the Precast girders and concreted properly according to the specifications.• Ensuring that post tensioning is done after the precast box girders attain their required strength.• Close monitoring of the progress of works by the contractor and his adherence to the PoW provided.• Supervision of bridge deck rebar installations, concrete casting, water proofing and laying of Asphalt Concrete (AC) • Writing daily reports which included the extent of work as per that day• Concrete quality control – though conducting compressive strength of concrete cubes, slump tests and giving recommendations.

CONSTRUCTION OF WEI WEI & LOMUT BRIDGES ALONG THE MARIGAT - MARICH PASS (B4) ROAD- WEI WEI Bridge is a 58m clear span Composite bridge. It consists of bored cast in place pile foundations, concrete sub structures i.e. abutments, modular steel girder superstructure with a reinforced concrete deck. - LOMUT Bridge is a 70m clear span Composite bridge. It consists of bored cast in place pile foundations, concrete sub structures i.e. abutments, modular steel girder superstructure with a reinforced concrete deck. - Both bridges had approach roads totaling to 500m and 800m in length for Wei Wei & Lomut bridges respectively. The general cross section includes; subgrade material fill, sub base consisting of cement improved gravel & Graded Crushed Stone (GCS) and 50mm thick Asphalt Concrete base. Surface dressing using 10/14 pre coated chippings was done later. My roles and responsibilities included;• Design of 2No. concrete crossing drifts at Marich Pass River and Wei Wei river to facilitate the crossings of heavy machines, since the existing bailey bridges could sustain a maximum weight of 10T• Checking and ensuring that all the shop drawings are in order.• Assist the Engineer in carrying out design reviews.• Preparation of project briefs for both bridges to be used in Technical Meetings.• Checking and confirming Interim Payment Certificates (IPC) and Fee Notes. • Writing minutes during site meetings.• Inspecting and ensuring all the Rebars are in place according to the drawing specifications before concreting.• Concrete quality control – though conducting compressive strength of concrete cubes, slump tests and giving recommendations.• Inspection of the steel modular parts and ensuring that all steel components are available.• Ensuring that all safety protocols & measures put in place are adhered to during all construction activities
