Introduction
Landscape development and site infrastructure form the backbone of any construction project, yet these critical components are often overlooked in the planning stages. Whether you’re a seasoned professional, a fresh graduate entering the construction industry, or a homeowner planning your dream house, understanding the lifecycle of landscape and infrastructure development can significantly impact the success of your project.
This comprehensive guide walks you through each stage of landscape development and site infrastructure in Indian construction projects—from initial planning to final handover and maintenance. We’ll explore methodologies, material requirements, stakeholder involvement, and compliance standards relevant to various project types: residential (independent homes, group housing, high-rises), commercial properties, and industrial facilities.
Understanding Landscape Development and Site Infrastructure
What Is Landscape Development?
Landscape development encompasses the design and creation of outdoor spaces, including:
- Gardens and green spaces
- Hardscaping (walkways, patios, retaining walls)
- Water features
- Outdoor recreational areas

Design Basis Calculation Example – Stormwater Drainage:
For a 1-hectare residential development in Mumbai:
Determine rainfall intensity (i):
- Mumbai 1-hour, 10-year return period rainfall = 90 mm/hr
Calculate runoff coefficient (C):
- Paved areas (40% of site): C = 0.90
- Landscaped areas (60% of site): C = 0.35
- Weighted C = (0.40 × 0.90) + (0.60 × 0.35) = 0.57
Calculate peak discharge using Rational Formula:
- Q = C × i × A
- Q = 0.57 × 90mm/hr × 1 hectare
- Q = 51.3 cubic meters per hour
Size drainage infrastructure accordingly:
- Main collection pipes: 300mm diameter
