Professional Ethics and Conduct
Professional ethics covers integrity, competence, and accountability. Understand core duties: act honestly and fairly, avoid conflicts of interest (or declare and manage them), maintain confidentiality, keep within your competence, and comply with law and codes of conduct. Know the difference between a conflict of interest (personal interest affecting judgment) and bribery or corruption (improper inducement), and that gifts and hospitality must be declared and proportionate.
Understand fairness in procurement: equal treatment of bidders, transparency, no disclosure of one bidder's price to another, and no collusion. Confidentiality covers client information and tender data. Whistleblowing protects those reporting wrongdoing. Competence means not accepting work beyond your skills without supervision, and keeping records accurate-never falsify measurements, timesheets, or certificates.
Traps: assuming a declared conflict is automatically acceptable without management; treating a small gift as always fine (context and policy matter); and confusing loyalty to an employer with a duty to report unlawful conduct.
Rule of thumb: if a decision could be questioned publicly, disclose it and document the reasoning before proceeding.
Worked example: An estimator is offered a weekend trip by a supplier just before tender close. Even if it may not change the price, it creates an apparent conflict. The correct action is to decline or declare it to the employer, record the disclosure, and ensure the supplier gains no advantage.
