Final answer:
The explicit dollar limit for construction using a government purchase card is not provided here. One must refer to official procurement guidelines or the Federal Acquisition Regulation for current limits.
Step-by-step explanation:
The dollar limit for construction when using a government purchase card is not explicitly provided in the information given. However, it is crucial to adhere to the official guidelines provided by the specific governmental body's procurement policies.
For federal government purchase cards in the United States, there are predefined micro-purchase thresholds that may be applicable to construction services, and these thresholds are periodically updated. To obtain the current applicable limit, one would need to refer to the most recent Federal Acquisition Regulation (FAR) or contact the agency's program coordinator for the government purchase card.
