Illustrative Decisions

COA Decision No. 2849 dated April 15, 1993

This is a claim for payment for dredging of various rivers in Pampanga and Bulacan under contracts of FF Cruz and DPWH. The Auditor noted that the volume of excavated materials for which payments were made in December 1985 and January 1986 could not have plausibly been dredged by the firm even if the dredging operations had started immediately upon the execution of the covering contracts, using the Ministry of Public Works and Highways' (MPWH) own formal and official evaluation of the equipment envisioned to be used and methods to be employed in the dredging operations.

The CP opined that since, as noted by the Technical Service Office, the submitted plans and cross-sections, in reference to which the agency's surveys were made, do not show the location or elevation of the bench marks for the projects, it cannot be ascertained whether the elevations shown in the cross sections based on the sounding made, refer to the same bench marks that would have been taken in original pre-dredging surveys. Nor is there an indication in the profile and cross-section maps of the water level and the status of the tide at the time sounding was made.

Likewise, the CP noted that the company failed to submit the following contract documentation requirements indicated in Section IB2-2.10 of the IRR of PD 1594:

(a) Approved programs of work
(b) Construction schedules
(c) Construction methods
(d) Manpower schedules
(e) Equipment Utilization schedules
(f) Cash flow and payment schedules
(g) Acceptable performance bonds
(h) Pre and post qualification statements
(i) Certification of cash deposits for operating expenses

Hence, the request for reconsideration was denied.

COA Decision No. 93-307 dated July 28, 1993

This pertains to the construction of a two (2) storey academic building of the Sorsogon College of Arts and Trades (SCAT), Sorsogon, Sorsogon. The winning bidder was sought to be disqualified, and suspension of payment was recommended on the ground of lack of prequalification requirements.

The CP, in its decision noted that the deficiency (non-submission of a credit line certificate-CLC, during the prequalification) may not be rightly attributed to the Contractor. It is indubitable from the checklist of required documents for prequalification issued by the PBAC to the herein Contractor that CLC was not among the required documents to be submitted by the latter for prequalification.

With respect to the alleged fake/forged CLC submitted by Jofel Construction, the CP did not consider the same as sufficient basis for disqualification of the contractor considering that the CLC was not a requirement of the PBAC.
