An ENG Form 4025 shall accompany each submittal. These forms will be furnished to the Contractor by the PM. The submittal file name shall be in the format “Contract # – submittal #, submittal name” for example;

“0020-001 RTU”. Properly complete this form by filling out all the heading blank spaces and identifying each item submitted. Drawings if required by the SOW shall be in ACAD format and a second electronic copy in PDF format. The Government reserves the right to request submittals not listed in this SOW; any submittals not listed in this SOW but requested by the Government shall become a requirement of the project. Submittals requiring Government approval are to be scheduled and made prior to the acquisition of the material or equipment covered thereby. Each submittal is to be complete and in sufficient detail to allow ready determination of compliance with contract requirements. Contractor shall check and approve all items prior to submittal and stamp, sign, and date indicating action taken. Proposed deviations from the contract requirements are to be clearly identified.

3.1.1. The Government reserves the right to require the contractor to resubmit any item found not to comply with the contract. This does not relieve the contractor from the obligation to furnish material conforming to the plans and specifications; will not prevent the KO from requiring removal and replacement of nonconforming material incorporated in the work; and does not relieve the contractor of the requirements to furnish samples for testing by the Government laboratory or for check testing by the Government in those instances where the technical specifications so prescribe.

3.1.2. Government Approval. Government approval is required for critical materials, deviations, equipment whose compatibility with the entire system must be checked, safety requirements, and other items as designated by the KO. Government approval is required for any deviations from the solicitation or accepted proposal and other items as designated by the KO. These deviations must contain proper documentation stating why this deviation is necessary and why it is beneficial to the government.

3.1.3. Information Only. Submittals not requiring Government approval will be for information only. The approving authority will not provide approval of information only submittals but shall provide acknowledgement of receipt.

3.1.4. Variations. Variations from contract requirements require Government approval pursuant to contract Clause FAR 52.236-21 and will be considered where advantageous to Government and/or overall project. Discussion with KO or their representative (DPW PM, MICC CS, etc.)

prior to submission will help ensure functional and quality requirements are met and minimize rejections and resubmittals. Specifically point out variations from contract requirements in transmittal letters. Failure to point out variations may result in the Government requiring rejection and removal of such work at no additional cost to the Government. When proposing a variation, deliver written request to the KO, with documentation of the nature and features of the variation and why the variation is desirable and beneficial to Government. In addition to documentation required for variation, include the submittals required for the item. Clearly mark the proposed variation in all documentation. Check the column "variation" of ENG Form 4025 for submittals that include proposed variations requested by the contractor. Set forth in writing the reason for any variations and annotate such variations on the submittal. The Government reserves the right to rescind inadvertent approval of submittals containing unnoted variations.

3.1.5. Approval. When approving authority is KO or the designated representative, the Government will:

Note date on which submittal was received. Review submittals for approval within scheduling period specified and only for conformance with project design concepts and compliance with contract documents. Identify returned submittals with one of the actions defined in paragraph entitled "Review Notations" and with markings appropriate for action indicated. Upon completion of review of submittals requiring Government approval, stamp and date approved submittals. The transmittal form (4025-R) showing approval of the submittal will be retained by the KO and one copy of the transmittal form will be returned to the contractor electronically. The KO's approval or acceptance of submittals is not to be construed as a complete check, and indicates only that the general method of construction, materials, detailing and other information are satisfactory.

Approval or acceptance will not relieve the contractor of the responsibility for any error that may exist, as the contractor is responsible for the satisfactory construction of all work. After submittals have been approved or accepted by the KO, no resubmittal for the purpose of substituting materials or equipment will be considered unless accompanied by an explanation of why a substitution is necessary.

3.1.6. Disapproval. Contractor shall make corrections required by the KO. If the contractor considers any correction or notation on the returned submittals to constitute a change to the contract drawings or specifications, notice as required under the clause entitled, "Changes" is to be given to the KO.

Failure to point out deviations may result in the Government requiring rejection and removal of such work at the contractor's expense. If changes to submittals are necessary, the contractor shall make such revisions and submission of the submittals in accordance with the procedures above within 7 calendar days. No item of work requiring a submittal change is to be accomplished until the changed submittals are approved.

3.1.7. Duration for submittal review: The Government shall have up to 14 calendar days to review each submittal starting when the Government receives the electronic submission. Longer review times may be required on a case-by-case basis.

3.2. Project Schedule:

3.2.1. Prepare for approval a Project Schedule, as specified herein, pursuant to the contract clause, SCHEDULE FOR CONSTRUCTION CONTRACTS. Show in the schedule the sequence in which the contractor proposes to perform the work and dates on which the contractor contemplates starting and completing all schedule activities. The scheduling of the entire project, including construction sequences, is required. The scheduling of construction is the responsibility of the contractor. Contractor management personnel shall actively participate in its development.

Subcontractors and suppliers working on the project shall also contribute in developing and maintaining an accurate Project Schedule. Provide a schedule that is a forward planning as well as a project monitoring tool.

3.2.1.1. Approved Project Schedule. Use the approved Project Schedule to measure the progress of the work and to aid in evaluating time extensions. Make the schedule cost loaded and activity coded.

The schedule will provide the basis for all progress payments. If the contractor fails to submit any schedule within the time prescribed, the Contracting Officer (KO) may withhold approval of progress payments until the contractor submits the required schedule.

3.2.1.2. Default Terms. Failure of the contractor to comply with the requirements of the contract shall be grounds for a determination, by the KO, that the contractor is not prosecuting the work with sufficient diligence to ensure completion within the time specified in the contract. Upon making this determination, the KO may terminate the contractor's right to proceed with the work, or any separable part of it, in accordance with the default terms of the contract.

3.2.2. BASIS FOR PAYMENT AND COST LOADING: Use the schedule as the basis for determining contract earnings during each update period and therefore the amount of each invoice payment.

Lack of an approved schedule update, or qualified scheduling personnel, will result in the inability of the KO to evaluate contractor percentage complete for the purposes of payment.

Failure of the contractor to provide all required information will result in the disapproval of the preliminary, initial, and subsequent schedule updates. In the event schedule revisions are directed by the KO and those revisions have not been included in subsequent revisions or updates, the KO may hold retainage up to the maximum allowed by contract, each payment period, until such revisions to the Project Schedule have been made. Activity cost loading shall be reasonable, as determined by the KO. The aggregate value of all activities coded to a contract line item number (CLIN) shall equal the value of the CLIN on the Project Schedule. The Government will withhold 5% of the project amount for submission and acceptance of any and all closeout documents as specified in each project and this shall be shown on the project schedule.

3.2.3. PROJECT SCHEDULE DETAILED REQUIREMENTS: The computer software system utilized to produce and update the Project Schedule shall be capable of meeting all requirements of this specification. Failure of the contractor to meet the requirements of this specification will result in the disapproval of the schedule.

3.2.3.2. Level of Detail Required. Develop the Project Schedule to an appropriate level of detail. Failure to develop the Project Schedule to an appropriate level of detail, as determined by the KO, will result in its disapproval. The KO will consider, but is not limited to, the following characteristics and requirements to determine appropriate level of detail:

a. Activity Durations. Reasonable activity durations are those that allow the progress of ongoing activities to be accurately determined between update periods. Procurement activities are defined herein.

b. Permit Activities. Include permit activities, when required, with the necessary conferences and follow-up actions and dates. Include the permitting schedule in the Project Schedule, showing the sequence of events involved in carrying out the project permit tasks within the specific contract period. This shall be at a detailed level of scheduling sufficient to identify all major permitting tasks, including those that control the flow of work.

c. Procurement Activities. Tasks related to the procurement of long lead materials or equipment shall be included as separate activities in the project schedule. Long lead materials and equipment are those materials that have a procurement cycle of over 30 days. Examples of procurement process activities include, but are not limited to: submittals, approvals, procurement, delivery, start-up, and testing.

d. Mandatory Tasks. The following tasks (as required) must be included and properly scheduled:

1. Submission of closeout submittals, equipment commissioning, controls testing plan submission, controls testing, performance verification testing, other systems testing, Contractor’s internal project inspection, correction of punchlist from the Contractor’s pre-final inspection, final inspection.

2. Government Activities. Show Government and other agency activities that could impact progress. These activities include, but are not limited to: approvals, environmental permit approvals by State regulators, inspections, utility tie-in, Government Furnished Equipment (GFE) and Notice to Proceed (NTP) for phasing requirements.

3. Contract Line Item Number (CLIN) Coding. Code all activities to the CLIN on the CLIN Schedule to which the activity belongs. An activity shall not contain more than one CLIN code. CLIN code all activities, even when an activity is not cost loaded (to include preconstruction and post construction activities).

3.2.4. Scheduled Project Completion and Activity Calendars. The schedule interval shall extend from Notice to Proceed (NTP) date to the required contract completion date. The contract completion activity (End Project) shall finish based on the required contract duration in the accepted contract proposal, as adjusted for any approved contract time extensions. The first scheduled work period shall be the day after NTP is received by the contractor. Schedule activities on a calendar to which the activity logically belongs. Activities may be assigned to a 7-day calendar when the contract assigns calendar day durations for the activity such as a Government Acceptance activity. Assign the Category of Work Code - Weather Sensitive Installation to those activities that are weather sensitive. Original durations must account for anticipated normal adverse weather. The Government will interpret all work periods not identified as non-work periods on each calendar as meaning the contractor intends to perform work during those periods.

3.2.4.1. Project Start Date. The schedule shall start no earlier than the date on which the NTP was acknowledged. Include as the first activity in the project schedule an activity called “NTP”.

3.2.4.2. Project Completion Date. Constrain completion of the last activity in the schedule by the contract completion date. Schedule calculations shall result in a negative float when the calculated early finish date of the last activity is later than the contract completion date. Include as the last activity in the project schedule an activity called "Project Completion”.

3.2.5. PROJECT SCHEDULE SUBMISSIONS: The contractor shall provide the submissions as described below:

3.2.5.1. Project Schedule Submission. Submit the Project Schedule for approval within 7 calendar days after NTP. The schedule shall demonstrate a reasonable and realistic sequence of activities which represent all work through the entire contract performance period. The Project Schedule shall be at a reasonable level of detail as determined by the KO. This requirement is in addition to any required schedules or submittals submitted in response to a Request for Proposal (RFP).

3.2.5.2. Project Schedule Updates. At the request of the KO, the contractor shall provide and submit an updated Project Schedule. These submissions will enable the KO to assess the contractor's progress. If the contractor fails or refuses to furnish the information and Project Schedule data, which in the judgment of the KO or authorized representative is necessary for verifying the contractor's progress, the contractor shall be deemed not to have provided an estimate upon which progress payment may be made.

3.2.6. REQUESTS FOR TIME EXTENSIONS: In the event the contractor believes they are entitled to an extension of the contract performance period, completion date, or any interim milestone date, furnish the following for a determination by the KO: justification, project schedule data, and supporting evidence (Ex: daily reports showing delays) as the KO may deem necessary.

Submission of proof of excusable delay, based on revised activity logic, duration, and costs (updated to the specific date that the delay occurred) is a condition precedent to any approvals by the Government. In response to each RFP issued by the Government, the contractor shall submit a schedule impact analysis demonstrating whether or not the change contemplated by the Government impacts the critical path.

3.2.6.1. Justification of Delay. The Project Schedule shall clearly display that the contractor has used, in full, all the float time available for the work involved with this request. The KO's determination as to the number of allowable days of contract extension shall be based upon the Project Schedule updates in effect for the time period in question, and other factual information. Actual delays that are found to be caused by the contractor's own actions, which result in a calculated schedule delay, will not be a cause for an extension to the performance period, completion date, or any interim milestone date.

3.2.6.2. Unexcused Delays. Unexcused delays will result in a disapproval of any time extension request and the Contractor will be required to complete the work within the original period of performance. If the Contractor cannot complete the work within the original period of performance, the Contractor will be required to provide consideration to the Government in order to receive a time extension. Consideration will be established on a case by case basis but examples include but are not limited to extended warranty period, upgraded materials, etc.

3.3. Accident Prevention Plan:

3.3.1. Use a qualified person to prepare the written site-specific APP. Prepare the APP in accordance with the format and requirements of USACE EM 385-1-1 and as supplemented herein. Cover all paragraph and subparagraph elements in USACE EM 385-1-1, Appendix A, "Minimum Basic Outline for Accident Prevention Plan". Specific requirements for some of the APP elements are described below. The APP shall be job-specific and address any unusual or unique aspects of the project or activity for which it is written. The APP shall interface with the contractor's overall safety and health program. Include any portions of the contractor's overall safety and health program referenced in the APP in the applicable APP element and made site specific. The Government considers the prime contractor to be the "controlling authority" for all work site safety and health of the subcontractors. Contractors are responsible for informing its subcontractors of the safety provisions under the terms of the contract and the penalties for noncompliance, coordinating the work to prevent one craft from interfering with or creating hazardous working conditions for other crafts, and inspecting subcontractor operations to ensure that accident prevention responsibilities are being carried out. The APP shall be signed by the person and firm (senior person) preparing the APP, the contractor, the on-site superintendent, the designated site safety and health officer and any designated CSP and/or CIH.

3.3.2. Submit the APP to the Government personnel within 14 calendar days prior to the date of the preconstruction conference for acceptance. Work cannot proceed without an accepted APP.

3.3.3. Once accepted by the KO or their representative, the APP and attachments will be enforced as part of the contract. Disregarding the provisions of this contract or the accepted APP will be cause for stopping of work, at the discretion of the KO, until the matter has been rectified.

3.3.4. Once work begins, changes to the accepted APP shall be made with the knowledge and concurrence of the KO, or their representative, project superintendent, SSHO, and quality control manager. Should any hazard become evident, stop work in the area, secure the area, and develop a plan to remove the hazard. Notify the KO within 24 hours of discovery. Eliminate/remove the hazard. In the interim, take all necessary action to restore and maintain safe working conditions in order to safeguard on-site personnel, visitors, the public (as defined by ASSE/SAFE A10.34,) and the environment.

3.3.5. Copies of the accepted plan will be maintained at the KO's office and at the job site. Continuously review and amend the APP, as necessary, throughout the life of the contract. Incorporate unusual or high-hazard activities not identified in the original APP as they are discovered.
