From Due Diligence to Detailed Design
Aegaea provides comprehensive support throughout all project stages, from initial due diligence and planning applications through to condition discharge and detailed civil engineering design.
Project challenges
Development projects require coordinated flood risk, drainage, and civil engineering input at every stage — from initial site acquisition through to construction completion. Many developers engage different consultants at different stages, leading to inconsistent design approaches, duplicated effort, and delays when planning conditions need to be discharged.
A common challenge is that flood risk and drainage constraints identified during the planning stage are not fully integrated into the detailed design, requiring costly redesign work and potential planning variations.
How we solved it
Aegaea offers a full lifecycle service covering every project stage. During pre-planning, the team provides due diligence assessments and pre-purchase constraint reviews to help clients understand investment potential. During the planning application stage, the team prepares FRAs and drainage strategies with detailed knowledge of local authority policies.
Post-planning, Aegaea assists with condition discharge at critical milestones — prior to completion, pre-occupation, and pre-commencement — regardless of who handled the original application. During feasibility and detailed design stages, the team provides civil engineering design for residential, industrial, commercial, and retail projects, including highway authority liaison, construction specifications, and drainage authority coordination under Sections 38, 278, 104, 106, and 185.
Results delivered
By maintaining continuity from due diligence through to detailed design, the approach eliminates the knowledge gaps and design inconsistencies that typically arise when different consultants are engaged at different project stages. The integrated service ensures that flood risk and drainage constraints identified during planning are carried through into construction-ready designs.
The team specialises in surface water disposal using SuDS hierarchy principles, external works design including finished floor levels, footpath locations, retaining walls, and earthworks calculations using industry-standard software.
Project Overview
Aegaea provides comprehensive support throughout all project stages, from initial due diligence through construction completion. This integrated approach ensures consistency between planning-stage flood risk and drainage assessments and the detailed civil engineering design that follows.
Pre-Planning Phase
Due Diligence
The team provides early expert consultation to identify development constraints and propose mitigation strategies. Pre-purchase and pre-planning assessments use various analytical tools to help clients understand investment potential cost-effectively, enabling informed decisions before committing to site acquisition.
Planning Applications
Early engagement during the planning phase improves approval prospects. The team understands local authority policies and works collaboratively to achieve permission, offering multidisciplinary or specialised civil engineering design services tailored to project needs.
Post-Planning Phase
Condition Discharge
Aegaea assists clients in meeting planning conditions at critical milestones — prior to completion, pre-occupation, and pre-commencement — regardless of who handled the original application. This flexibility is particularly valuable for developers who may have used a different consultant during the planning stage.
Feasibility and Design
During feasibility stages, civil engineering design significantly influences construction costs. The team provides detailed design for residential, industrial, commercial, and retail projects. Services include highway authority liaison, layout drawings, construction specifications, and drainage authority coordination under Sections 38, 278, 104, 106, and 185.
