2.70     RELEASE OF TEMPORARY EASEMENT (Right of Way Form 636‑069)

Property that the Department requires temporarily for the construction of a highway construction project is acquired by means of a "Temporary Easement."  Temporary easements are typically acquired for the construction of driveways, borrow pits, or right of entry.  The temporary easement will be acquired by the Office of Right of Way and documented on a Right of Way Contract.


Most acquisition contracts are written so that the termination of temporary easements occurs when the construction project is completed and action to release the easement is not required of the project engineer.


On selected Right of Way contracts (i.e. temporary easement only or borrow agreements), the release of temporary easement is not automatic. In these instances, the temporary easement is released in accordance with the following instructions:


After the temporary easement is acquired, the Office of Right of Way will prepare the "Release of Temporary Easement" (Form 636‑069) and forward it to the project engineer.  The form will be retained in the project engineer's office until the temporary easement is released.


When the temporary easement is no longer needed for highway construction, the easement should be "released."  While it is important that easements be released as soon as possible after completion of the project in order to minimize the Department's responsibility of the property, the project engineer should consider needs of future projects.  For example, a grading project may be completed, but a borrow pit may be needed on the subsequent paving project.


To release a temporary easement, the project engineer shall:

n  Sign and date the completed "Release of Temporary Easement" form

n  Obtain notarization of Notary Public

n  Submit signed "Release of Temporary Easement" (Form 636‑069) and "Order Claim" (DOT Form 635037) to the County Recorder (county in which temporary easement exists)


After the release of easement is recorded, the County Recorder will send the "Release of Temporary Easement" and "Order Claim" to the Office of Right of Way.  The Office of Right of Way will retain the release and process payment to the County Recorder for the recording fees.



A “Bridge Inventory Report” (ie: Bridge 2000) is required to be completed for all new Iowa DOT bridges constructed.  This report is also required to be completed for all new culverts constructed when the culvert has an overall span length of 20 feet or greater.  The report serves as a permanent record of design, construction, and maintenance data of the structure.  The information provided in this report and from future maintenance inspections is used to develop sufficiency ratings for the structures and determine apportionments of bridge funds.


The Resident Construction Engineer should have a copy of the Federal Highway Administration’s “Recording and Coding Guide for the Structure Inventory and Appraisal of the Nation’s Bridges” to assist in filling out the form.


The Office of Bridges and Structures initiates the report with additional information included by the Project Engineer following completion of construction.  A “Bridge Inventory Database” was developed in Microsoft Access 2000.  This database is maintained by the Office of Research & Analytics with design data input by the Office of Bridges and Structures and construction data input from the Project Engineer administering the project.


The “Bridge Inventory Report” database is located in the following server address:


            U:\idot\access\prod\bridge2000.mdb              At password prompt enter:  bridge


The “Bridge Inventory Reports” are processed through this database as follows:


§  Office of Bridges and Structures will initiate the report by completing the Section A portion.  Once completed the Section A portion is submitted into the “Bridge Inventory Database” in “Access” and is available to users.  For situations where the Project Engineer is unable to locate a completed Section A in the “Bridge Inventory Database”, contact the Office of Bridges & Structures for assistance.  You will need to provide the county, project number, and structure design number when requesting assistance.


§  The Project Engineer will enter the Date Open to Traffic at the time this occurs for any bridge or culvert with a span length of 20 feet or greater. This field is located within the Bridge Inventory Form at the top of Section B. The project will not necessarily be complete at this time. In order to keep the DOT’s structure inventory up to date and reflective of what customers are driving throughout the road network; the Office of Analytics is requiring the Project Engineer to notify them immediately of the Open to Traffic Date of any structure that is being added or replaced.  This provides the Office of Motor Carriers up to date information when routing over size/overweight loads across the state by traveling on or under newly open structures. Please note, Section B does not need to be completed for the project at the time it is opened to traffic if all work has not been completed to be able to measure and report the updated clearances.


§  The Project Engineer shall complete Section B of the report and select the check box at the top of the form once the construction project is complete.  The Office of Bridges & Structures has a policy that initial bridge inspections are conducted within 90 days of completion of a bridge or culvert project.  As soon as all related construction has been completed to be able to report clearances, you are required to take the necessary measurements, and enter them into Section B with the other required data for processing by the Office of Research and Analytics.   NOTE:  All data entries for both Section A and Section B shall be in English units.


Additional information available:


1.     The Resident Construction Engineer is responsible for reporting information on Section B of the Bridge Inventory Report.

2.     The District Engineering Operations Technicians are responsible for periodically reviewing clearance information on structures in their Districts and updating this information on Form 220206 which can be found on the Iowa DOT website.

3.     For all Bridge 2000 users the following information  is provided at the identified links:

The project engineer shall have one set of "as‑built" plans prepared for construction projects as soon as possible after project completion either by manual methods or electronically using Spicer Imagination software through the Citrix environment.


At the time of letting, the project engineer will receive two sets of full‑size plans for the construction project.  One set is to be reserved for the "as‑built" plan when using the manual method, while the second set is intended to be used during the construction project.  If an electronic as-built is completed, the second set can be recycled or used during construction.


When revising information on the plan with "as‑built" information, the voided information should be lined out manually or electronically.


The "as‑built" plan shall include the actual quantities included in the project, as well as items added to the project by Contract Modification that change physical features of the project.


It is not necessary to change wording in the "as‑built" plan from future tense to past tense.


The title page of all as-built plans should include the certification block (Form 370-520003) with the name of the contractor, year of project completion, project engineer’s signature and certification.


The project engineer shall forward the manual completed as-built plans to Records Management in Ames with a copy of the transmittal letter to the District Office.  Electronic as-built plans should be saved in ERMS according to ERMS guidelines.  A For manual plan submission, a cover letter is to accompany the plans describing the size and number of plans which are to be reproduced.


The following adhesive‑backed standard formats are available from the Office of Construction and Materials:

As‑Built Certification Block                                        370‑520003

Corps of Engineers’ Section 404 Permits require that “Wetland Mitigation As-Constructed Drawings” be submitted to the Corps within 30 days of the completion of the mitigation sites. These drawings are separate from the usual DOT “As-Built” plans. “Wetland Mitigation As-Constructed Drawings” are more detailed site maps that are used to confirm compliance with mitigation agreements and to monitor future performance of the wetland. The information varies with the permit, but typically includes before/after cross-sections, location and elevation of water control structures, monitoring sites, final boundary of constructed wetlands, list of plant species, photos, depth of transplanted topsoil, geometry and treatment of buffer areas, ditch plugs, drain tiles and boundary markers.


The Office of Location and Environment (Wetlands Section) will retain a consulting engineering firm to complete the “Wetland Mitigation As-Constructed Drawings” for wetland projects to comply with the 404 Permit requirements.  Once completed, two full-size copies should be sent, with a cover letter to the Office of Location and Environment and to the Resident Construction Engineer. If a consulting firm is administering the project, copies will be sent to the District Office.


Right of Way

All right‑of‑way lines should be darkened and the station and offset included for all right‑of‑way breakpoints.  Location of right‑of‑way corners should be identified.  If the plan and profile sheets become too crowded when the right‑of‑way information is included, this information may be included on a separate plan sheet.


Information regarding access should be included on the "as‑built" plan, including the limits of access rights purchased and location of constructed and deleted entrances.


As a minimum, the parcel information should include the owner’s name and parcel number.  Temporary easements do not need to be shown on the "as‑built" plan.


Land Section Corner Ties

During “as-built” plan preparation, the final land section corner ties information shall be reviewed with the District Land Surveyor.  A plan sheet of the corrected land section corner ties shall be included in the "as‑built" plan. 

Tied Projects

Tied projects should include references on the “as-built” plan title sheet that list other projects included in the contract.  Project quantity item numbers should correspond to the item numbers shown in the contract, by plan.  “As-builts” for each plan should be completed separately, as they will be filed individually in the Records Center.


As-Built Plans Checklists

See Appendix 2-37.5 for checklists to use in developing As-Built plans.



The Department will be responsible for relocating water stop boxes on projects that require a property owner to be responsible for the cost of relocating their water stop box.


The relocation of water stop boxes will be included as a contract item on the construction project.  If the plans do not include relocation of water boxes, the item should be added to the contract by change order.


The basis of payment for relocation of water stop boxes shall include disconnecting, relocating, and reconnecting to the existing service line.  The property owner shall be responsible for the cost of installing a new service line from the water stop box to the building.



Iowa DOT Policy No. 500.05, "Preconstruction Project Agreements," establishes the responsibilities for obtaining project agreements.
