Speaking with the contractors on Friday it seems the problem my well be ongoing. It could be a while, and far more reaching works may be looming.The Gas mains were already worked on along with adjacent services in recent times. But the axle loads of HGVs and several years of poorly maintained road surfaces, have increased what is known as 'Hammer Blow' which send shock waves do depths of 6m.  Now it seems the weight of nearby new buildings is causing settlement and has created some pressure points.  The surveyors are a little concerned that it may also be affecting the A4 flyover foundations although they are much deeper and substantial. Monitors are to be fitted.Locals ( and especially cyclists and those with small cars) may recall that the junction of South Ealing Road has had potholes and and uneven surface for at least 2 decades and no proper repairs. Even the resurfacing did not deal with the subsidence until the most recent resurfacing. The Ealing Road side is similar.In the meantime the axle load on HGVs has increased and South Ealing Road carries too many HGVs. Even the buses are nearly a third heavier than types used until the 1990s. One problem with new hybrid and electric buses is their weight is even greater and axle loads plus full passenger loads make for considerable weight on roads simply not constructed for such pressure. The problem is the contracts and specifications for maintenance and repairs are based on the minimum of everything - Profits are at stake.  They are based on out of date specs for loadings that were superseeded decades ago.  It's been a case of brushing over the cracks which, of course, has a knock on for the ageing infrastructure buried below.So diversions and delays in this district, given that the infrastructure is very old and complex as it all converges on the former sites of a Gas works and water supply works is likely to increase hugely with developments that are not taking into account of the inadequate infrastructure that has only been remedied for the existing envirion and not what is being planned.This is really another example of why all the basics need to be planned and in place before any sort of large developments are even considered and why these factors need to be considered with far more gravitas than current.
