Construction Management Software for Karachi
Tailored for the unique construction standards of Karachi. Estimate in square yards (gaz), manage solid concrete block inventories, and track material purchases in the local market.
Karachi Sizing Standards: Estimating in Gaz (Square Yards)
Unlike upper Punjab where plots are measured in Marlas, Karachi's real estate and construction sectors are strictly structured around square yards, referred to locally as gaz. Residential construction revolves around standard formats: 120 square yards (small plots), 240 square yards (medium villas), and 400 or 600 square yards (large residential sites).
Squinchos (skwin-chos) features a built-in Gaz converter in its estimation engine. Karachi builders can instantly input their dimensions in square yards, and the calculator automatically expands it to square feet (1 square yard = 9 square feet) to execute precise material calculations for grey structure works.
Local Materials: Hub Sand and Manghopir Crush
Karachi's proximity to the coast influences local structural material selections:
- Concrete Block Masonry: Due to the local climate and soil conditions, red clay bricks are rarely used in Karachi. Instead, structural masonry relies on concrete blocks—both solid and hollow blocks. Squinchos allows you to customize the masonry database to log block dimensions (typically 6x8x12 or 4x8x12 inches) and track block inventory counts rather than standard bricks.
- Hub River Sand: Fine aggregate is predominantly sourced from the Hub River bed. Because Hub sand carries varying levels of silt and salinity, tracking water-cement ratios and concrete admixture costs is critical to prevent future reinforcement corrosion.
- Manghopir & Nooriabad Crush: Coarse aggregate is sourced from the limestone quarries of Manghopir or Nooriabad. Our software lets you pre-load these specific supplier rates so you can track trollies and dumpers with zero billing discrepancies.
Combating Maritime Corrosion and Cost Escalations
Karachi's humid, high-saline coastal atmosphere accelerates steel oxidation, making structural integrity a primary concern. Most projects in Clifton, DHA, and KDA schemes require epoxy-coated or specialized Grade 60 steel reinforcement.
Because these materials carry a premium, over-ordering steel leads to severe cash flow leaks. Squinchos gives site owners real-time inventory visibility. You see exactly how many tons of steel have been delivered to your DHA Phase 8 site, what has been consumed in slab casting, and what remains in stock, preventing site theft and waste.
