Provide more than the exposed wall height
A useful wall estimate needs the length, top and bottom elevations, embedment, corners, steps and available working room. Show nearby buildings, pavement, property lines and utilities. Identify traffic, stored materials or slopes above the wall because those conditions affect the design. If a wall already exists, include its material, condition and the proposed removal limits.
Price the system shown in the design
Wall units or blocks, base materials, drainage aggregate, reinforcement and backfill requirements vary by system and site. Provide the engineer's or supplier's details and installation requirements. Excavation and access behind the wall may extend beyond its visible footprint. Any alternative system should be reviewed by the responsible designer before it is treated as an approved substitution.
Include drainage and the finish condition
Identify the drainage outlet, surface-water control, final grades and restoration limits. Separate removal and disposal of the old wall from new construction. Include imported material, exported soil and required testing in the pricing request. Construction access, fencing, railings, engineering and approvals should each have an assigned responsibility rather than being assumed part of the wall price.
Project questions
Can you compare retaining wall options?
We can price clearly defined alternatives and review their construction requirements. The responsible designer must confirm that a proposed system is suitable for the site and loads.
Is retaining wall engineering included?
Only if expressly included in the proposal. Share the approved design when available; design responsibility and required approvals must be established before construction.
Can the wall be part of a larger sitework package?
Yes. Wall work can be coordinated with building excavation, parking areas, drainage, aggregate placement and finish grading.
