By using innovative value for money construction techniques, Humqadam-SCRP is the only school's infrastructure development programme in Pakistan which is providing safe, secure and healthy environment to children in government schools of Punjab and Khyber Pakhtunkhwa provinces.

Despite widespread use in other South East Asian countries Rat-trap bond technique, in conjunction with lime mortar, is an innovative construction technique, being used for the first time in Pakistan, which is not only eco-friendly but also cost effective. By using this technique, Humqadam-SCRP has contributed to saving 1,475 CO2 tonnes of embodied carbon in completed schools as of March 2018, when compared with the more traditional construction technique of English brick bond. This technique also increases insulation in the classrooms, which makes the classrooms warmer in winter and cooler in summer.

Using Rat-trap bond, Humqadam-SCRP is directly contributing to environmentally friendly schools by using fewer bricks. The number of bricks per cubic ft. in regular/English Bond is 13.5 where as the number of bricks per cubic ft. in Rat-trap bond is 9.8. Altogether in completed schools, more than 2.7 million bricks were saved for the construction of new classrooms, toilets and other facilities.
