Need tight access drilling? Call 415-457-5658 for a prompt, reliable estimate from our experienced estimator. RWR has been doing tight access and track drilling in San Francisco for over 24 years. You will see our trucks and equipment working in San Francisco neighborhoods like the Marina, Pacific Heights, Nob Hill, Western Addition, Haight, Castro, Noe Valley, Twin Peaks and so on.

Here’s the kind of detailed estimate you can rely on, to correct foundation problems and perform structural work, including even zero lot line jobs that require our expertise:

This estimate is based on structural drawings, architectural drawings and landscape drawings, and structural drawings provided by contractor. The scope of work is for a house addition foundation including some site walls and for a new guest house/garage foundation. The estimate includes demo of concrete, excavation and off haul, drilling, installing concrete piers, installing concrete grade beam, slabs and CMU walls. The price includes all labor and material to complete the work as per the itemized scope of work below. Prices broken out are for illustration purposes only and not self supporting.

Scope of Work

Main House

Mobilization and Layout
• Mobilize to jobsite with track drilling rigs, portable drilling rigs along with other necessary equipment to complete job (See notes below).
• Layout to be completed by General Contractor per plans and specifications
• Daily Cleanup
• Final Cleanup

Note: All soft demo and safe off of utilities to be completed by others prior to mobilization. Our estimate will demo the existing foundation as required. The estimate assumes the use of a track drilling rig for a number of the piers and portable drilling rigs where the track rig is unable to access. In addition it recommends replacement of existing wood retaining wall below work site. Landscape plans call for wall to be “renovated”. The wall has a number of rotted timbers. Will be performing excavation, drilling and installing new concrete above this wall and as such it is not responsible or liable if wall fails during construction.
