Specifications and Disputes - Examples & Applications

A fictional concrete clause specifies a mix procedure and a tested 28-day compressive strength. Identify the two requirements and whether either label alone proves which party bears a failure loss.

A private project specification names Product A “or approved equal.” A contractor proposes Product B with similar catalogue claims but no submitted evidence of performance or approval. May the contractor assume substitution is authorized?

A drawing calls for concrete class C1 while technical specification clause S3 calls for class C2. The contract contains no clearly applicable precedence rule and no clarifying addendum. What is the defensible next action?

A fictional signed agreement states that numbered addenda control over earlier drawings when inconsistent. Addendum A2 specifies a 150 mm item, while an earlier drawing shows 125 mm. Explain the working interpretation pending required design confirmation.

Excavation reveals an uncharted buried obstruction not shown in the issued site information. The contract requires written notice to a designated representative but its deadline has not been provided in the problem. What should be documented immediately?

A hypothetical authorized additional excavation is measured at 25 m³ and the agreed variation rate is ₱4,500/m³. Compute the priced quantity before any contract-specific taxes, overhead, or adjustments.

A log shows eight days of disruption associated with one issue, of which three days overlap an independently delaying activity. What is the non-overlapping calendar count in this simplified record, and what cannot yet be concluded?

During construction a supervisor verbally asks for a material substitution. The contract requires written changes from a named representative; the supervisor's authority is unclear. Explain the appropriate response.

An illustrative change record includes ₱112,500 of approved priced excavation and ₱18,000/day of documented site expense for six days. Find the arithmetic subtotal before deciding whether every item is claimable.

A contract encourages negotiation and allows mediation but contains no dispute-board clause. A party claims it must first convene a three-person board, then arbitrate, then litigate. Evaluate the claimed mandatory ladder.

A Philippine construction contract includes a written arbitration clause. The owner and contractor dispute certified unpaid work and variations. A party proposes an ordinary civil action solely because the other party has not separately signed a fresh CIAC submission. Identify the central jurisdiction issue without pre-deciding the lawsuit.

A contractor and project owner in the Philippines dispute payment, but the supplied documents show no arbitration clause and no subsequent submission agreement. Does the phrase “construction dispute” alone establish CIAC jurisdiction?

A construction worker brings an employment wage dispute against the employer. The project contract between owner and contractor contains a CIAC arbitration clause. Is that clause enough to treat the worker's wage claim as a CIAC construction-contract dispute?
