PE Civil Exam Changes 2027: New Design Standards [2026]

Every few years, the codes and standards that engineers design with are updated, and the PE exam eventually updates its references to match. For PE Civil candidates, that moment is April 2027, when NCEES switches every depth exam to a new list of design standards. The good news is that the change is narrower than the rumors suggest, and NCEES has already published exactly what it is. This guide explains what changes in April 2027, what each depth's new standards are, and how to decide when to take the exam.

What changes on the PE Civil exam in April 2027?

Beginning with the April 2027 exams, NCEES updates the design standards supplied in all five PE Civil depth exams. Some standards move to newer editions, some are added, and a few are removed or folded into other documents. Because answers that rely on a standard are scored against the edition NCEES lists, your study references must match your exam date.

During the exam, every PE Civil candidate works with the NCEES PE Civil Reference Handbook plus a depth-specific list of design standards, which are the codes and manuals (such as ASCE 7 or the Highway Capacity Manual) supplied onscreen as searchable files. NCEES publishes that list in each depth's exam specification, and it has posted the April 2027 versions on its PE Civil exam page.

The size of the change differs a great deal from depth to depth:

A new edition of a standard can change more than page numbers. Load factors, coefficients, procedures, and even the structure of a chapter can shift between editions, which is why a question written for one edition can have a different correct answer under another.

What stays the same on the PE Civil exam

The April 2027 update does not change the exam itself. The knowledge areas and question ranges in every depth's specification stay exactly the same, and so do the 80-question format, the 9-hour appointment, closed-book computer-based testing with onscreen references, and year-round scheduling.

This point is worth stating plainly, because "the PE exam is changing" is often heard as "the PE exam is being rewritten." It is not. Comparing the current and April 2027 specifications line by line, the topics and the approximate number of questions in each knowledge area are identical. A Transportation candidate will still see the same traffic, geometric design, and drainage topics; only the manuals used to solve some of those questions change.

That has a practical consequence for your preparation. Your understanding of the engineering, and the PE Civil Reference Handbook equations you practice with, carry over unchanged. What you need to adjust is narrower: the specific editions you look values up in, and the procedures that a new edition handles differently. For an overview of the exam format and the five depths, see our PE Civil exam guide.

PE Civil Structural: 2027 design standards

PE Civil Structural sees the largest change of any depth: almost every design standard moves to a newer edition, including ASCE 7, ACI 318, the AISC Steel Construction Manual, the IBC, and the AASHTO LRFD Bridge Design Specifications. The wood design rule (Allowable Stress Design only) stays the same.

For Structural candidates, this is effectively a new reference library. The jump from ASCE 7-16 to ASCE 7-22 alone touches the load calculations that feed most structural questions, and the move to ACI 318-19 affects concrete design provisions across the board. If you studied with the older editions and your exam date slips past April 2027, plan time to rework your load and design problems in the new editions rather than assuming the values carry over.

PE Civil Transportation: 2027 design standards

PE Civil Transportation changes two standards: the Highway Capacity Manual moves from the 6th to the 7th edition, and the MUTCD moves to its 11th edition. The geometric design, pavement, roadside, safety, pedestrian, and culvert references stay the same.

These references stay unchanged: AASHTO's A Policy on Geometric Design of Highways and Streets (7th edition), Guide for Design of Pavement Structures, Guide for the Planning, Design, and Operation of Pedestrian Facilities, Highway Safety Manual, Mechanistic-Empirical Pavement Design Guide, and Roadside Design Guide, plus FHWA's Hydraulic Design of Highway Culverts (HDS-5).

Only two documents change, but both sit at the center of the Traffic Engineering knowledge area, the heaviest in the Transportation specification. Capacity and level-of-service analyses follow the HCM, and signing, marking, and signal questions follow the MUTCD, so candidates should practice those problem types with the new editions in hand.

PE Civil Construction: 2027 design standards

PE Civil Construction adds ACI 318, removes the masonry wall bracing standard, moves the AISC Steel Construction Manual and the MUTCD temporary traffic control part to new editions, and adds an OSHA recordkeeping part. ACI 347R is not dropped; it is now included inside ACI SP-4.

ASCE 37-14 (Design Loads on Structures During Construction) and PCA's Design and Control of Concrete Mixtures stay unchanged. The addition of ACI 318 is the most significant change for preparation: Construction candidates can now expect questions that lean on the concrete design code itself, not only on formwork and mixture references.

PE Civil Geotechnical: 2027 design standards

PE Civil Geotechnical adds the FHWA Geosynthetic Design and Construction Guidelines, replaces the Navy's Foundations and Earth Structures design manual with its Unified Facilities Criteria successor, and updates ASCE 7 and the OSHA construction regulations. The FHWA foundation and site characterization manuals stay the same.

The rest of the Geotechnical list carries over: the USACE Slope Stability manual (EM 1110-2-1902), FHWA's Geotechnical Aspects of Pavements, the two-volume Soils and Foundations Reference Manual, the Geotechnical Engineering Circulars on seismic design, driven piles, site characterization, and drilled shafts, and the UFC criteria for dewatering and for soil mechanics. Geosynthetics is the area to watch, since a new dedicated manual usually means questions that use it.

PE Civil Water Resources and Environmental: 2027 design standards

PE Civil Water Resources and Environmental grows from two design standards to seven. The Ten States Standards for wastewater facilities and water works stay, with the Water Works standard moving to a newer edition, and five federal documents are added covering construction safety, slope stability, culverts, energy dissipators, and dewatering.

For Water Resources and Environmental candidates, the new documents map onto knowledge areas the exam already tests: culverts and energy dissipation sit in open-channel hydraulics, slope stability in soil mechanics, and excavation safety and dewatering in project sitework. The topics were always there; from April 2027, more of those questions will expect you to work from a specific federal procedure. Our PE Civil Water Resources and Environmental exam guide covers all 12 knowledge areas of this depth in detail.

Should you take the PE Civil exam before or after April 2027?

Take the exam whenever you are ready, and study the standards list that matches your appointment date. If you can comfortably test before April 2027 and you already studied the current editions, testing early avoids relearning. If your date falls in or after April 2027, study the new editions from the start.

There is no advantage built into either side of the switch: the knowledge areas and question counts are the same, and NCEES does not publish a passing score that would favor one window. What matters is consistency between your references and your exam. The real risk is a candidate who prepares with the current editions and then schedules, or reschedules, into April 2027 or later without updating.

A few guidelines help with the decision:

• Already deep into preparation with the current editions? Book a date before April 2027 if your schedule allows, and leave a buffer in case you need to retake within the old window.
• Starting your preparation now with an exam date near the transition? Study the April 2027 list, since a later exam is the safer assumption and the topics are identical.
• Structural candidates have the most to relearn after the switch, so the timing question matters most for them; Geotechnical and Transportation candidates face a narrower adjustment.

Whatever you choose, confirm the specification and standards list that apply to your appointment in your MyNCEES account, and buy or access references in the editions on that list. Our guide to how to study for the PE exam covers building a study plan around your exam date, and our PE Civil Water Resources and Environmental Practice Exams prepare every standard-dependent question for both the current and the April 2027 standards, so practice can match whichever window you test in.
