Project Delivery Methods: Worked Decisions

A private clinic signs a design services contract with an engineer and a separate construction contract with a builder. A site detail conflicts with the issued drawing. Identify the first contractual interface to resolve.

A privately financed logistics warehouse is procured under one integrated design–build contract. The design-builder's consultant draws a drainage slope inconsistent with the employer's requirements. Who receives the owner's contractual correction notice?

A private company needs a process facility with civil works, pumps, control equipment, testing and commissioning. Compare a separate civil contractor plus five equipment vendors against an integrated EPC arrangement.

A school owner hires a CM consultant for ₱1.5 million to coordinate four owner-held trade contracts. An electrical trade package exceeds its budget by ₱600,000. Does the CM's advisory fee constitute a guaranteed construction price?

For a private DBB project, Tender A is ₱240 million with authorized changes later totaling ₱18 million; Tender B, for a directly comparable hypothetical scope, is ₱252 million with ₱3 million in changes. Which has the lower final expenditure?

A project has 9 months of design, 2 months of procurement and 16 months of construction under sequential DBB. Under a hypothetical integrated DB arrangement, construction starts 6 months after design begins and takes 16 months from that start. Compare calendar durations, ignoring holidays and permitting delays.

A private owner negotiates a ₱90 million GMP that expressly includes ₱3 million contractor contingency. A later owner-approved scope addition is valued at ₱5 million and, by the signed change mechanism, increases the GMP. What is the adjusted limit for covered work?

Two compliant private-project alternatives have initial prices of ₱120 million and ₱132 million. Over an assumed ten-year period, estimated O&M costs are ₱4.0 million/year and ₱2.0 million/year, respectively. Ignore discounting solely for this screening exercise.

An LGU plans a classroom with government funds and no long-term private operation, finance or concession arrangement. A bidder calls its integrated tender a “PPP” because it provides both design and construction.

A government implementing agency's hypothetical privately financed toll-road proposal was approved before 23 December 2023 but competitive procurement had not begun by that date. May the reviewer simply apply the old BOT law to everything?

For an illustrative PPP concept, annual user-charge revenue is projected at ₱130 million and annual O&M plus financing cash requirements at ₱105 million. A downside demand case lowers revenue by 25%, while expenses remain unchanged. Compute the annual difference; do not infer legal concession eligibility from it.
