Subject: - MONITORING REPORT REGARDING “UP-GRADATION OF 150-HIGH SCHOOLS TO HIGHER SECONDARY LEVEL (B&G: 30:70) IN KHYBER PAKHTUNKHWA ON NEED BASIS ” ADP NO. 15/100280 SH: GHS NOGRAM DISTRICT BUNER

S/No. Analysis and recommendation Replies1- For the work to be executed the TS is essential to be in hand

before the execution, but here the executing agency have intentionally delayed the process of approval of TS so that to cover the lapses in planning and implementations. It is recommended that the concerned agency should expedite the process of approval; also no scheme in future should be put into execution until the TS is approved.

Technical Sanction Estimate has been submitted to Competent Authority for approval and will be available for verification in short time.

2- “The soil bearing capacity test of the strata and all the materials used in the structure formation has gone under laboratory testing as stated by Sub Engineer of the executing department” but the data of the tests performed has not been shared with DMO Office Malakand Division which clearly indicates that the concerned department is intentionally not keeping up the standard work procedures. It is recommended that the Non Destructive Tests must be conducted and the C&W Department Buner should justify the basis of design for the structure build up.

Laboratory test are being carried in routine for every work along-with field tests and visual examinations of the material. All the necessary tests have been done and record is available for verification. The test reports were not available at site and instruction has been issued to field staff to maintain separate file for all laboratory test at site and copies thereof will be available to M&E at site in future.

3- Following are the observations regarding sub standard workmanship and supervision maintained at the execution site by the C&W Department District Buner.

I The plaster carried out at the projection of the school building (Pic-I) of the steps of the boundary wall (Pic-2) of the wall in the Verandah on first floor (Pic-3) and that of window frame executed in the store area in the laboratory No. 1 on first floor (Pic-4) was not in plumb showing lack of proper supervision from the concerned staff of the executing department.

The defective plasters have been removed & rectified properly after re-plastering and can be verified at site. The supervision of work is carried out as per available strength of field staff, which is not At-Par with the sanctioned strength and the work load. However all possible efforts are made to ensure the quality of work at site.

II The frame work of the RCC beam constructed in the laboratory no.1 on the ground floor was not properly braced which resulted in the bulging of concrete as shown in photograph. This reflects that poor workmanship and supervision was maintained at site.

The deficiency has been rectified and can be verified at site.

III The alignment of the columns built up on the ground floor did not matched with the columns alignment on the first floor (Pic-10. The columns on the ground, first and second floors were titled towards inner side (Pic-2). This situation is making the lines on load taking capacity of columns weaker which will be risk toward safety of structure and also the students.

The column for first floor and Ground floor as pointed out are Verandah columns and not the main columns, and the eccentricity impact is not that much influential because of continuity of slab and beams, minimum load and safety factor in the Design. Similarly, one column appears out of alignment due to extra concrete over and above the actual column section and verticality of centre line is mentioned.

IV Cracks were observed in the projection and the beam columns joint in the first floor (Pic-1 and Pic-2 respectively). Also cracks were notified in the wall of the store portion in the laboratory constructed on first floor (Pic-3). The wall of the hall / class room built on second floor was cracked (Pic-4).

All the short coming / deficiencies have been rectified, after removal of old plaster and new plaster has been carried out. This is worth mentioning that these are mostly hair cracks which occur normally in plaster and at joint of concrete and brick work.

V Round aggregates were used in the RCC columns of the verandah as shown in photographs. This will increase the workability of the concrete but it will weakens the bond / interlocking strength between the aggregate and will results in collapse of the structure. While the rougher surface (angular aggregates) generates a stronger bond between the cement paste and the aggregate (concrete creating a higher strength.

Only crush from approved sources is allowed for the concrete works sometimes round aggregates are got included in the mix due to poor sieving of sand. The tests of concrete have been carried out and which confirm to the standard strength criteria. Copies of test results are attached.
