Site Investigations: Assess site conditions.

Prior to acquiring a new building site, a meticulous survey is imperative to ensure that the site aligns seamlessly with the envisioned development concept. This comprehensive checklist offers essential guidance for a thorough site analysis.

Importance of site investigation

In the initial phase of any construction project, site investigation stands as the cornerstone. This section highlights the important role played by comprehensive site investigation in laying the foundation for successful and sustainable development. Understanding the importance of this initial stage is paramount to any construction endeavor.

Ensuring alignment with the development concept

A careful survey is mandatory before purchasing a new building site. This subsection explores the important aspect of ensuring that the site seamlessly aligns with the envisioned development concept. By carrying out a thorough site investigation, developers can confirm that the chosen location is not only suitable but also effectively harmonizes with the proposed development plans. Alignment with the development concept sets the stage for a successful and well-executed construction project.

Key Considerations: Site Investigations Checklist

1. Map Exploration: Look at detailed maps to spot nearby features, roads, facilities (Hospitals, schools, parks Gym Etc.), footpaths, and rights of way.
2. Measure Things: Take accurate measurements to figure out how much space you’ve got and how high or low things are.
3. Check the Lay of the Land: Take a good look at the surface—trees, slopes, buildings, rocks, and wells—to understand what nature’s already offering.
4. Ask the Locals (Local Authorities): Check with local authorities to learn about any rules that might affect your site, like preservation orders or if it’s in a special conservation area.
5. Dig a Little Deeper (Subsoil Investigation): Get your hands dirty by checking what’s under the surface. Trial holes and borings help you understand the quality of the soil and where the water table sits.
6. Keep Water in Check: Think about flooding possibilities and how to manage water—whether it’s capping springs, filling ponds, or redirecting rivers.
7. Utilities 101: Chat with utility companies to know where underground and overhead services are and if they cross your site.
8. Spot Red Flags: Look for warning signs like filled ground, cracks, or past subsidence, and check existing buildings for any structural issues.
9. Blend In with the Neighbours: See how your plans fit in with the neighbourhood. Think about the size and style of nearby buildings.
10. Find the Sweet Spot for Your Building: Figure out the best place to put your building. Consider things like the land slope, how much sun it gets, and how practical it is to access.

Preliminary Steps: Desk/Office Study

1. Collect data from various sources, including Ordnance Survey maps for grid references.
2. Analyze geological maps for subsoil types and radon risk.
3. Examine site history, distinguishing between green-field and brown-field areas.
4. Review previous planning applications and approvals.
5. Assess current planning applications and identify development restrictions.
6. Consider utilities’ locations and examine aerial photographs.
7. Evaluate ecology factors, such as protected wildlife.
8. Incorporate local knowledge and assess the proximity of landfills.

Field Study or Walk-Over Survey

1. Conduct intrusive visual and physical activities to establish site characteristics.
2. Assess health and safety hazards.
3. Appraise surface conditions, including trees and topography.
4. Investigate ground conditions, identifying the water table, flood potential, and soil types.
5. Evaluate engineering and financial risks.
6. Take subsoil samples and conduct in-situ tests.
7. Consider subsoil exploration, trial pits, and boreholes.
8. Appraise existing structures for re-use, refurbishment, archaeological value, and demolition considerations.

Laboratory Analysis:

1. Conduct detailed laboratory analysis, emphasizing subsoil samples for identification and classification.
2. Utilize trial pits and augured holes to identify geological faults and water table limits.
