Final answer:
Basic services in Construction Procurement include assisting in obtaining proposals, issuing documents, preparing addenda, analyzing proposals, advising on contracts, gaining client approval, and preparing construction contracts. Pre-qualification of Bidders is considered an additional service.
Step-by-step explanation:

These would cover: Assisting and advising the client in obtaining bids or negotiated proposals; Issuing Bid Documents; Preparing and coordinating addenda as applicable; Analyzing bids or negotiated proposals; Assisting and advising in awarding and preparing construction contracts; Review and obtaining client approval before proceeding to the next phase; Preparation of Construction Contract(s).
