DEVELOPMENTAL SPECIFICATIONS
FOR
GIRDER ERECTION PLAN
Effective Date
October 17, 2023
THE STANDARD SPECIFICATIONS, SERIES 2023, ARE AMENDED BY THE FOLLOWING
MODIFICATIONS AND ADDITIONS. THESE ARE DEVELOPMENTAL SPECIFICATIONS AND THEY
SHALL PREVAIL OVER THOSE PUBLISHED IN THE STANDARD SPECIFICATIONS.
23023.01 DESCRIPTION.
This work shall consist of developing, engineering and submitting a detailed Girder Erection Plan which shall
include erection plans and procedures substantiated with appropriate erection engineering calculations.
23023.02 CERTIFICATION.
The Girder Erection Plan submittal consisting of erection plans and procedures shall be certified by a
Professional Engineer licensed in the State of Iowa, known in this document as the Erection Engineer.
Erection engineering calculations used in the preparation of the Girder Erection Plan shall only be
submitted if requested by the Engineer. If the Engineer requests erection engineering calculations, they
shall be submitted with the certification of the Erection Engineer.
23023.03 DETAILS OF GIRDER ERECTION PLAN SUBMITTAL.
A. Review.
The Engineer shall be allowed a minimum of 30 working days to review the submittal. The
Engineer shall provide notification to the Contractor either indicating “No Exceptions Taken” or
“Revise and Resubmit”.
B. Erection Plans and Procedures Overview.
1. The term “erection plans” refers specifically to the engineering drawings prepared by the
Erection Engineer describing and specifying the erection (i.e., the field-installation and
member-placement) of the structural steel. Erection Plans may also refer in a more general
context to the combination of engineering drawings and erection procedures describing and
specifying the erection (i.e., the field-installation and member-placement) of the structural
steel.
2. The term “erection procedures” refers to the documents which describe the specific
sequence, methods, equipment, and other directives that the Contractor is to follow in
erecting the structural steel. The terms “erection plans” and “erection procedures” are not
synonymous, but the erection plans and erection procedures shall be fully integrated with
each other and shall together describe and specify all aspects of how the structural steel is to
DS-23023, Page 2 of 5
be erected, including, but not limited to, sequence of erection, methods or techniques to be
used, equipment to be used, and materials to be used along with any temporary works or
other devices necessary.
3. The erection plans and procedures shall address all requirements for erection of the
structural steel into the final designed configuration. Any and all written review comments
provided by the Engineer shall be addressed to the Engineer’s satisfaction prior to the start of
erection. As a minimum, the erection plans and procedures shall include consideration of all
items described in Article D below.
C. Erection Engineering Calculations.
1. Appropriate erection engineering calculations to substantiate the structural adequacy and
stability of the bridge system for each step of the steel erection shall be performed to
substantiate the erection plans and procedures.
2. At a minimum and as appropriate, erection engineering calculations shall conform to the
following guide specifications:
• Guide Design Specifications for Bridge Temporary Works, AASHTO, 2nd Edition, 2017
• Guide Specifications for Wind Loads on Bridges During Construction, AASHTO, 1st
Edition, 2017
3. Erection engineering calculations to substantiate the structural adequacy and stability of the
erected structure and any associated temporary works and/or temporary components do not
need to be included in the Girder Erection Plan submittal. However, the Engineer reserves
the right to request the submittal of erection engineering calculations for review and approval
at any time. If requested, such calculations shall be submitted within 14 calendar days of
request by the Engineer.
D. Erection Plans and Procedures.
1. Plan of Work Area.
The erection plan shall include:
• A plan of the work area showing the proposed bridge,
• The permanent support structures (piers and abutments),
• Roads,
• Railroad tracks,
• Waterways (including location and dimensions of any navigational channel(s) and any
navigational clearances which must be respected during construction),
• Overhead and underground utilities,
• Structures and conditions that may limit access (consideration of clearance requirements
over roadways or railroads),
• Staging or material storage areas,
• Right-of-way and property lines,
• Information, plans, etc. regarding maintenance of traffic requirements, lane or road
closures, restrictions, durations, etc. necessary to protect public safety for all erection
operations over or adjacent to live traffic, and
• Any other information that may be pertinent to the steel erection.
2. Erection Sequence.
The erection plans and procedures shall indicate the erection sequence for all primary
members (including indication of any attached secondary members), noting the use of
temporary support conditions, such as holding crane positions, temporary supports,
DS-23023, Page 3 of 5
falsework, etc. The erection sequence shall be shown in an illustrative plan view of the bridge
for each erection stage, highlighting the structural components to be erected, their weights
and center of gravity locations, lifting crane locations for primary member picks, and any
temporary support conditions that are necessary during the particular stage. The illustrative
plan view shall be accompanied with a written narrative of the procedure to be followed by
the steel erector, which shall state items such as structural components to be erected, use of
temporary supports, use of temporary bracing, hold cranes, etc. Member reference marks,
when reflected on the erection plans and procedures, should be the same as used on shop
detail drawings.
3. Delivery Location.
The submittal shall indicate the delivery location and orientation of all primary members.
4. Crane Information.
a. The erection plans and procedures shall show the location of each crane to be used for
each primary member to pick (see Article 23023.03, D, 2), the crane type, crane pick
radius, crane support methods (crane mats, barges, work trestles, etc.), and the means

23082.03 CONSTRUCTION.
A. Production Concrete.
1. Notify the Engineer at least 48 hours prior to placement of production concrete. Use only
approved HPC mixes for production concrete. If a mix other than mix described in Article DS-
23082.02, A or B is to be used, ensure it has same materials, proportions, and properties
(including slump, air content, and w/c ratio) as approved by the District Materials Engineer.
2. District Materials Engineer will obtain random verification strength samples on a minimum of
one deck placement. Strength samples will be tested at District Materials Laboratory
according to AASHTO T 22. A set of four cylinders will be cast, cured, and handled according
to Materials I.M. 315. Three cylinders will be tested for strength at 28 days. One cylinder will
be tested for permeability on a random basis by Central Materials Laboratory or Wenner
probe resistivity testing by the District Materials Engineer. Permeability testing will not be
evaluated on footings or drilled shafts.
B. Placing Concrete.
For the deck, placing of concrete floors shall not begin if the theoretical rate of evaporation
exceeds 0.1 pounds per square foot per hour. Monitor theoretical evaporation rate at a maximum
interval of every three hours during placement at a location as near the deck as possible. If the
rate exceeds 0.15 pounds per square foot per hour cease placement at next location acceptable
to Engineer.
C. Curing.
1. Substructure.
a. Leave forms in place for 96 hours of curing.
b. Apply curing protection to exposed surfaces of concrete in accordance with Article
2403.03, E, 4, b. Leave curing protection in place for 96 hours.
2. Deck.
a. Leave forms in place for 168 hours of curing.
b. Apply water to the burlap covering for 168 hours of continuous wet sprinkling system
curing.
c. Do not place curing compound on floor.
d. Use burlap that is prewetted by fully saturating, stockpiling to drain, and covering with
plastic to maintain wetness prior to placement. Place two layers of prewetted burlap on
floor immediately after artificial turf drag or broom finish with a maximum time limit of 10
minutes after final finishing. Apply water to burlap covering for entire curing period by
means of a continuous wet sprinkling system that is effective in keeping burlap wet during
moist curing period.
DS-23082, Page 3 of 3
e. Use evaporation retardant only in situations where equipment and/or labor delays, or
environmental conditions, prevent adequate protection of concrete until prewetted burlap
is in place. Have an evaporation retardant, including Confilm, Conspec Acquafilm,
Evapre, or Sure Film, readily available during placement for application as directed by the
Engineer. Do not work evaporation retardant into concrete surface or use as a finishing
aid.
D. Cold Weather Protection.
1. Furnish results to Engineer in electronic format as required. Apply Article 2403.03, F of the
Standard Specifications.
2. Replace the provisions of Article 2403.03, F, 5, d, of the Standard Specifications with the
following:
a. Substructure.
The duration of required cold weather protection shall be the first 120 hours after placing.
Ensure concrete and its surface temperature are maintained at a temperature of no less
than 50ºF for the first 120 hours after placing. Curing time will not be counted if concrete
temperature falls below 50ºF. Following completion of the cold weather protection period,
regulate the rate of concrete cooling to prevent thermal shock, until the concrete
temperature falls within 35ºF of ambient air temperature.
b. Deck.
The duration of required cold weather protection shall be the first 168 hours after placing.
Ensure concrete and its surface temperature are maintained at a temperature of no less
than 50ºF for the first 168 hours after placing. Curing time will not be counted if the
