Code of Ethics

Civil engineering decisions shape structures, transport, water systems, drainage, foundations, construction sites, public spaces, and other systems that people depend on without being able to personally verify the engineering behind them.

Professional trust therefore depends on more than technical calculation. Civil engineers must also demonstrate:

• honesty and impartiality;
• competence and appropriate restraint;
• respect for lawful professional boundaries;
• clear documentation and traceability;
• independence from improper influence;
• willingness to disclose material uncertainty and error;
• responsible supervision and delegation; and
• continuing development as laws, hazards, codes, materials, methods, and tools evolve.

PICE states that civil engineers uphold and advance the integrity, honor, and dignity of the profession by:

• using their knowledge and skill for the enhancement of human welfare and the environment;
• being honest and impartial and serving with fidelity the public, their employers or employees, and clients;
• striving to increase the competence and prestige of the civil engineering profession; and
• supporting the professional and technical societies of their disciplines.

These Fundamental Principles describe the profession's broad ethical direction. The Fundamental Canons convert that direction into more specific duties.

Canon 1 establishes priority. A civil engineer should not knowingly allow a client preference, employer directive, schedule target, cost reduction, aesthetic objective, or internal political pressure to override a mandatory safety requirement or conceal a material public danger.

Public welfare includes foreseeable effects on:

• occupants and users;
• construction and maintenance workers;
• road users and pedestrians;
• adjacent properties and infrastructure;
• downstream or affected communities;
• environmental systems and resources; and
• future operators, maintainers, and emergency responders.

The duty is not satisfied by minimum-code checking alone. Engineers must also use reasonable professional judgment to recognize hazards, uncertainty, deterioration, constructability, temporary conditions, and failure consequences that may not be captured by a single checklist.

Sustainability should be integrated with safety and service performance rather than treated as a decorative project claim.

Ethically relevant considerations include:

• lifecycle energy and resource use;
• durability and maintainability;
• resilience to hazards and changing climate conditions;
• water, waste, emissions, and ecosystem effects;
• material efficiency and responsible sourcing;
• adaptability and end-of-life considerations; and
• equitable access to infrastructure benefits and burdens.

Sustainability claims should be supported by evidence and should not be used to justify noncompliance with mandatory structural, safety, accessibility, environmental, or professional requirements.

Competence has at least four dimensions:

• legal competence: the professional service is within the lawful scope of the license or permit being used;
• technical competence: the engineer has the knowledge and skill needed for the specific problem;
• experiential competence: the engineer has sufficient relevant experience or appropriate specialist support and supervision; and
• organizational competence: the engineer has access to adequate information, time, tools, checking, quality controls, and other resources needed to perform the work responsibly.

A license is necessary for regulated professional practice, but licensure alone does not establish unlimited competence across every civil engineering specialty.

Philippine building practice provides a clear example of why competence and scope must be separated.

• RA 544 establishes the broad statutory domain of civil engineering.
• RA 1582 permits qualifying civil engineer-architect professional firms while expressly requiring each member to render only services proper to that profession and remain responsible for individual acts.
• RA 9266 regulates architecture and reserves architectural documents relative to building construction to registered and licensed architects under Section 20.
• In DPWH v. PICE / UAP v. PICE, G.R. Nos. 200015 and 205846, 15 March 2023, the Supreme Court held that RA 9266 impliedly repealed RA 544 insofar as RA 544 permitted civil engineers to prepare, sign, and seal architectural documents.
• The building-permit framework separately recognizes civil engineers for civil/structural documents and other licensed professionals for their respective document sets.

The ethical rule is straightforward: coordinate across disciplines, but do not use technical familiarity, employment position, or a multidisciplinary firm to bypass another profession's regulated responsibility.

Canon 3 applies to reports, testimony, certifications, presentations, marketing, social media, public comments, expert opinions, and technical communications.

A civil engineer should:

• distinguish facts, assumptions, estimates, judgments, and opinions;
• disclose material limitations and uncertainty;
• avoid selectively presenting data in a misleading way;
• correct material errors when discovered;
• cite or identify the actual basis of technical claims;
• accurately state professional qualifications, project roles, and experience; and
• identify sponsorship, advocacy, or interested-party relationships when they are material to the audience's interpretation.

Truthfulness also applies to internal engineering evidence.

Unethical practices include:

• inventing laboratory, survey, inspection, or monitoring results;
• altering data to force compliance;
• backdating documents or signatures;
• claiming an inspection occurred when it did not;
• omitting failed tests or nonconformance without a defensible disposition;
• using calculations from another project without verifying applicability; and
• presenting unverified AI-generated or software-generated results as independently checked engineering evidence.

Good records should be traceable to sources, dates, revisions, responsible persons, assumptions, and approval decisions.

Civil engineers should protect legitimate client and employer interests, confidentiality, property, schedules, and resources while preserving independent professional judgment.

Faithful service does not require obedience to an instruction that is unsafe, illegal, deceptive, corrupt, or outside professional authority.

A professional should clearly distinguish:

• client objectives from engineering requirements;
• confidential information from information that law or public-safety duty requires to be reported;
• advocacy for a client from distortion of technical evidence; and
• commercial negotiation from technical approval.

Potential conflicts should be identified before they distort professional decisions.

Examples include:

• ownership or financial interest in a supplier whose product the engineer recommends;
• undisclosed compensation from multiple parties for the same matter;
• evaluating one's own disputed work while presenting oneself as independent;
• accepting gifts or benefits intended to influence specification, inspection, certification, or payment;
• using confidential bidding or design information for personal advantage;
• steering work to a related firm without required disclosure; and
• allowing personal relationships to affect professional selection, inspection, or enforcement decisions.

Depending on the situation, the correct response may be disclosure, informed consent where permitted, safeguards, recusal, reassignment, or complete avoidance.

Professional reputation should arise from demonstrated quality, competence, reliability, ethics, and value rather than improper influence.

Unfair or unethical competition can include:

• false claims about credentials or experience;
• bribery, kickbacks, or improper gifts;
• plagiarism or passing another engineer's work off as one's own;
• malicious false statements intended to damage a competitor;
• misuse of confidential proposal information;
• deceptive fee representations; and
• arrangements that encourage unqualified or unauthorized practice.

Legitimate professional criticism is different from unfair attack. Engineers may identify technical deficiencies when the criticism is evidence-based, relevant, fair, and professionally communicated.

Compensation methods may include salary-based arrangements, hourly or per-diem services, lump-sum or fixed fees, cost-based methods, and other lawful professional-service arrangements.

Ethical compensation requires more than selecting a fee formula. Engineers should ensure that:

• the scope of services and exclusions are clear;
• fee structure does not create undisclosed conflicts;
• compensation does not depend on falsifying or manipulating a technical conclusion;
• the arrangement complies with applicable procurement and competition rules; and
• the professional has enough time and resources to perform the agreed service competently.

A low fee does not excuse inadequate professional care.

Canon 6 captures conduct that may not fit neatly within a single project calculation but directly affects professional trust.

Examples include:

• refusing to lend a professional seal or registration number;
• refusing to conceal a material defect;
• maintaining accurate records and authorship;
• acknowledging and correcting significant errors;
• respecting intellectual property and attribution;
• avoiding harassment, retaliation, discrimination, and abusive professional conduct;
• cooperating with lawful investigations and technical review; and
• avoiding conduct that deliberately misleads the public about professional responsibility.

Civil engineers may delegate drafting, modeling, data processing, field collection, calculations, and other tasks to qualified personnel when permitted and appropriately supervised.

Responsible delegation requires:

• clear task scope and acceptance criteria;
• personnel matched to task complexity;
• review proportionate to risk;
• independent checks for critical assumptions or results;
• documented revisions and approvals; and
• escalation when delegated work exceeds the person's competence or authority.

The professional who accepts final responsibility cannot defend a serious error merely by saying that a subordinate, software package, consultant, or AI system produced the work.

Civil engineering changes continuously through new laws, hazards, codes, research, materials, analytical methods, construction technology, digital tools, and societal expectations.

Continuing development should include:

• current professional laws, regulations, and Board issuances;
• technical specialty knowledge;
• codes, standards, and specifications;
• safety, resilience, sustainability, and environmental responsibilities;
• digital engineering, BIM, software, data, automation, and AI literacy;
• communication, contracts, leadership, and supervision; and
• lessons from failures, disputes, claims, audits, and peer review.

Supervisors should provide junior engineers with progressively responsible work, review, feedback, exposure to field conditions, and opportunities to understand the professional reasoning behind decisions.

When evaluating conduct, separate the questions:

• Legal authority: Was the person authorized by law to perform the regulated professional service?
• Technical competence: Did the professional possess or obtain the capability needed for the assignment?
• Standard of care: Was the work performed with appropriate professional skill and diligence under the circumstances?
• Ethical conduct: Were public welfare, truthfulness, conflicts, fairness, integrity, and professional development handled appropriately?
• Contractual duty: What additional obligations were accepted by agreement, provided they do not contradict mandatory law or public policy?

A professional decision may fail more than one of these tests at the same time.

Digital tools can improve productivity, checking, visualization, and access to information, but they do not possess a professional license and do not assume legal responsibility.

Ethical use requires the engineer to:

• protect confidential and sensitive project information;
• verify equations, units, assumptions, loads, boundary conditions, and code references;
• detect fabricated citations or unsupported conclusions;
• understand important model limitations;
• independently check safety-critical results;
• disclose tool use when required by law, contract, employer policy, academic policy, or professional context; and
• retain human professional judgment for decisions carrying regulated responsibility.

Professional respect does not mean avoiding legitimate review.

Civil engineers should:

• provide fair, evidence-based technical criticism;
• give appropriate credit and attribution;
• avoid malicious or knowingly false attacks on another professional;
• respect confidential and proprietary information;
• avoid taking over another professional's regulated responsibility through improper signing or sealing;
• cooperate in multidisciplinary coordination; and
• raise serious safety or integrity concerns even when doing so is uncomfortable.

Peer review is strongest when disagreement is documented around evidence, assumptions, requirements, and risk rather than personality or status.

For a difficult professional situation, use a structured sequence:

1. Define the issue: identify the safety, competence, truthfulness, conflict, corruption, scope, environmental, or professional concern.
2. Identify affected parties: include the public, workers, users, communities, client, employer, contractor, regulators, and future operators.
3. Gather facts: distinguish verified evidence from assumptions and unknowns.
4. Identify controlling duties: law, regulation, jurisprudence, code, contract, professional ethics, and organizational procedure.
5. Screen out unlawful options: ethics cannot authorize an act prohibited by controlling law.
6. Develop feasible alternatives: seek options that satisfy safety, legality, and legitimate project objectives.
7. Evaluate consequences and uncertainty: consider severity, reversibility, likelihood, transparency, and long-term effects.
8. Consult appropriately: involve specialists, supervisors, legal counsel, regulators, or ethics resources when needed.
9. Decide and document: record the evidence, reasoning, communication, decision, and required action.
10. Escalate when necessary: use proportionate internal or external channels if serious danger or misconduct remains unresolved.
11. Verify closure: confirm that corrective action was implemented and remained effective.
