AIS H-11 Project (Progress Report of September 2016)

AIS H-11 Project (Progress Report of September 2016)

Management Summary

The Project “AlHuda International School” was formally initiated two years ago in August 2014 by submission of drawings to CDA. The drawings were principally approved in June 2015 and work on-site formally began in August 2016 after the much needed clearances were obtained from Fire Directorate, Estate Directorate and Building Control Section.

The process for vendor selection had been initiated when the drawings were approved in June 2015 so no time was lost in mobilizing the work. An Engineering and Contracting firm of good repute, M/s Widecon has been awarded the Civil and MEP works amounting to a total of approx. PKR 380 Million (excluding HVAC work, which is to be awarded yet). A Mobilizing advance of approx. PKR 45 Million has been released. Widecon has recently completed a major school construction project in Islamabad and has ample human resources, material and machinery available to satisfactorily execute the AIS Project within the stipulated duration of 18-20 Months. The HVAC component of the Project would be awarded to a specialized vendor and necessary communications are being carried out in this regard.


Progress and Deviations from Plan

Activities carried out in till date

The excavation work of raft foundation initiated on 18th August, 2016 and is 100% complete as per plan, despite a couple of heavy rains. In parallel, the necessary facilities have been constructed on site for the technical and non-technical Project staff. The earth work is substantial and amounts to more than 600,000 cu. ft.

Work on steel procurement for raft is underway and necessary quantity take off has been carried out by Contractor. The raft would be 40 inch thick and would have 215 ton steel (in addition to around 35 ton steel in retaining walls). The raft would be supported by 24 inch thick bed of compacted gravel and would have 10 inch thick RCC retaining walls. Work on gravel bed is 100 % complete and currently the lay out of raft has been marked and excavation of lift shaft pit and  sump pits is complete.

Moisture-Density field testing was carried out by Civil Works Organization (CWO) staff and a reasonable 97% average compaction was reported.

To ensure that work is carried out as per Specifications, necessary due diligence is being carried out at each step of the Project. The Steel foundry selected by Contractor was visited by AIS Engineer to overview their production capacity and quality and was found satisfactory. Similarly, the gravel to be laid in raft foundation has been tested and it’s characteristics documented. The mix design for both 5500 psi and 7000 psi concrete has been carried out. The desired 7 day strength and 28 day  was achieved in the 5500 psi mix whereas another trial mix has been prepared for 7000 psi for which testing would be carried out after 7 days and 28 days.

There have been no deviations from the agreed upon time line or scope of work in terms of Specifications.

Projected activities, risk and risk mitigation techniques

Activities Planned for October 2015

  • Termite proofing
  • Lean concrete (1:2:4 ratio , 3000 psi)
  • Lay out of Steel in Raft foundation, lift pit, sump pits, isolated footings and retaining walls.
