Remedial Design Process. In most cases, the Remedial Design phase will be initiated with the development of the RD Work Plan, a secondary document. For simple remedies, a separate RD Work Plan may not be necessary and the typical elements of the RD Work Plan could be incorporated into the RD/XX XXX. For complex remedies, a separate RD Work Plan may be developed for each identified work element. The RD Work Plan will include: Scope of preliminary and/or draft design documents Cost estimate for the RD phase Requirements for correlations between plans and specifications Identification of substantive permit requirements (see Part VII C of the Agreement) Identification and schedules for the preparation of other design elements (e.g., Additional Required Studies, Operation and Maintenance (O&M) Plan, Quality Assurance Project Plan (QAPjP), Site Health and Safety (H&S) Plan) Design approval procedures and requirements. Given the critical nature of the RD, it will be necessary to provide the agencies with early design documents to ensure that consensus is maintained. This will be accomplished through the submittal of secondary design documents. In general, at least one secondary design document, the Preliminary Design, will be submitted. The Preliminary Design will typically represent 30% completion of plans and specifications. If available, preliminary results of any additional required studies may be included. The Remedial Design will include: Plans and specifications for remedial action including design analysis and construction drawings and specifications Cost estimate for remedial action O&M Plan QAPjP Site H&S Plan Results of additional required studies, if any. The Draft RD (Prefinal Design) will include all aspects of the design and be essentially complete. It will be considered representative of approximately 90% design completion. The final 10% of the design will include the resolution of comments on the Draft RD and preparation of reproducible construction drawings and specifications ready for bid advertisement. These changes and additions will be included in the Draft Final RD, which is the 100% design.
