Quantitative Solar Performance Analysis for Window and Shade.

Image
In May 2018, I shared a simple Excel workbook that let anyone see—and play with—the relationship between the sun, façade orientation, window size, and external shading. The goal was deliberately modest: make the physics transparent, keep the formulas visible, and let stakeholders validate design choices with their own eyes rather than accept a black-box simulation.

From Black Box to Spreadsheet: Engineering Certainty into Construction Project Control

Project management theory has advanced tremendously over the last generation. In practice, however, it has often fostered overconfidence and contributed to failure. Construction contracts frequently require submission of a project schedule in MS Project or Primavera, yet these documents often become little more than a paper formality with limited ongoing use.

Two primary concerns for construction professionals are the opacity of black-box software and the risk of AI hallucinations. Opting out of either technology is no longer realistic. Nevertheless, professionals of real standing must keep basing and defending their decisions on sound principles, hard-won experience, and verifiable results.   Excel, when used  with full visibility , lets us leverage AI and beat the hallucination curse. 

CPWD PAR (Plinth Area Rates) 2025 Analysis and the way to sustainability

Excel has natively supported data extraction from text files and databases for over a decade. Still, the ability to directly import structured data from PDFs was a major milestone introduced in 2020 via Power Query.  Today, integrating Copilot makes this process frictionless. In a well-structured document, the AI does more than ingest raw numbers—it inherently interprets the underlying data, its broader significance, and the strategic logic behind the publication's intent. On that account, i.e., explaining the tables and how to use them for preliminary estimation, the CPWD's PAR2025 document (freely available on the   CPWD Publications | Document | Central Public Works Department, Government of India website ) passes the AI usability test. 

Domain expertise in the AI age?

AI Will Not Replace Construction Professionals — It Will Empower Them While AI is transforming industries worldwide, it does not threaten the future of construction engineers and managers — it enhances it. Across the project lifecycle, AI will automate repetitive tasks, optimise scheduling, predict risks, and improve efficiency. This frees professionals to focus on what truly matters: complex problem‑solving, on‑site leadership, innovation, and the delivery of safer, more sustainable projects. Construction professionals who embrace AI as a strategic partner will be best positioned to lead this evolution. The opportunity ahead is not disruption— it is transformation. It is a chance to build better, faster, greener, and with far greater clarity than ever before.

Construction Project Management AI Use Cases

Image
Until recently, MS Excel and MS Project were the primary tools for construction managers. While these tools remain essential, the advent of AI has not only made them more accessible but also unveiled numerous innovative use cases that previous generations could only have dreamed of. This blog has historically explored potential use cases in construction projects and provided essential templates in their simplest forms, available in both MS Project and Excel formats—each ready for an AI-powered transformation. Let us start exploring possibilities.

Improving Urban Service Delivery with 3D Maps

The 3D Map feature in Excel allows us to quantify parameters with context to their location. In the figure, below the feature has been used to calculate the volume of water stored in a peri-urban lake.
