A slab, walk, driveway, retaining feature or masonry repair performs as a complete assembly. In Damascus, the scope should define excavation, base, drainage, dimensions, reinforcement, joints, finish, placement access and curing before price comparison. Confirm address-specific review questions with Clackamas County and verify the contractor through Oregon CCB.
Require measured limits, demolition, subgrade findings, compacted base, drainage, thickness, reinforcement, joints, finish, access, weather protection, cure, permit responsibility, cleanup and restoration.
Remove organic material and identify fill, soft areas, roots and water before establishing price. Specify excavation limits, base material, depth and compaction. When soil remains uncertain, use a measured unit rate for authorized over-excavation rather than a broad contingency. A strong surface placed over an unstable or saturated base can still settle and crack.
Record roof discharge, yard drainage, slopes, foundations and downhill property relationships. Show where runoff from the completed surface is intended to travel. Walls need drainage and a reliable outlet where design requires it. The proposal should not solve one puddle by directing water toward a doorway, foundation or neighboring property.
Provide the footprint, thickness, steps, edges, wall height and key finished elevations. Check door thresholds, garage slabs, walks and property boundaries. A dimensioned sketch gives forms an objective layout and shows whether access remains usable. Field interpretation without control points can create trip edges or drainage reversals that are expensive to correct.
State reinforcing material, spacing, support and relationship to retained work. Define isolation, control and construction joints. Reinforcement can help hold cracked sections together but does not remove shrinkage or soil movement. The bid should explain whether dowels connect assemblies or whether a joint deliberately allows independent movement.
Retaining walls depend on retained height, surcharge, soil, footing, reinforcement and water management. Confirm when design and permit review apply to the exact property. The scope should show drainage material, outlets, backfill and surface-water control rather than pricing only visible block or concrete. Added fence or driveway loads must be disclosed before design.
Broom, trowel, exposed aggregate and decorative finishes differ in traction, maintenance and repairability. Approve a sample or clear reference and state edge treatment, color expectations and acceptable variation. If a sealer is proposed, identify product, application timing and maintenance. Surface appearance cannot compensate for missing base, slope or joint details.
Document truck or pump access, gates, overhead lines, landscaping, occupied routes, demolition hauling and washout. Identify who protects and restores paving, lawn and adjacent finishes. The placement plan affects labor and joint locations, so it belongs in the bid. Keep people and pets away until the contractor releases the work for use.
The contractor should follow the specified mix and product requirements for placement temperature, wind, rain, finishing and curing. Ask how fresh work is protected and when foot, vehicle or construction loads may return. Collect material information, inspection results where applicable, photographs, cure instructions and warranty terms before final payment.
Describe your project once and we help connect your request with relevant local contractors who serve your area. The request is free, there is no obligation to hire, and you decide whether anyone is right for the job.
Confirm the exact property and scope with the responsible office rather than relying on a generic exemption.
Homeowners can verify contractor license and related public record information.
Slope, base, wall drainage and outlets should be explicit before placement begins.
| Work | Primary risk | Bid evidence |
|---|---|---|
| Walk or patio | Settlement and ponding | Base depth and finished slopes |
| Driveway | Vehicle load and cracking | Thickness, joints and reinforcement |
| Retaining work | Soil and water pressure | Design, footing and drainage |
| Repair | Movement cause remains | Diagnosis and repair boundary |
Separate demolition, hauling, excavation, base, drainage, forms, reinforcement, concrete or masonry, finish, pumping, access protection, curing, permit duties and restoration. Measured quantities and site conditions matter more than an unsupported unit-price headline.
Thickness depends on use, loads and design; require the proposed dimension in the written scope.
No. It affects crack behavior, while base, water control, joints, placement and cure also matter.
Record finished slopes, adjacent grades, wall drainage where applicable and the intended outlet.
Confirm height, loads, location and current requirements for the exact Damascus property with Clackamas County.
Match the legal business and CCB number to Oregon's public record.
Photograph and measure it, then approve a defined excavation and base correction before placement.
Follow the mix, weather and contractor's cure instructions for the intended foot or vehicle load.
Keep material information, approved changes, inspection records, photographs, cure instructions and warranty terms.
Share dimensions, photographs, intended loads, access and drainage concerns so contractors can quote a complete assembly.
