Three sitework bids sit on the table. The cheapest number looks heroic. Then Masaru sees the goblin hiding in the exclusions: dirt quantities, utility crossings, stormwater scope, erosion control, testing, trenching, and “by others.”
If a bid excludes erosion control, unsuitable soils, utility crossings, testing, traffic control, or stormwater scope, the number is not comparable to a complete bid.
Cut/fill, import/export, trench spoils, compaction, rock, unsuitable material, and hauling assumptions can change fast.
Detention, inlets, erosion control, SWPPP maintenance, street tracking, and runoff management can become schedule and compliance risk.
The cheapest bid may be real. Or it may be incomplete. Masaru checks the scope before celebrating.
Cut/fill, import/export, hauling, rock, unsuitable soils, moisture conditioning, and compaction.
Storm drains, inlets, basins, outfalls, erosion control, SWPPP support, maintenance, and cleanup.
Wet utilities, dry utilities, trenching, sleeves, crossings, laterals, service points, and utility coordination.
Compaction tests, pressure tests, soils reports, special inspections, and agency-required documentation.
Construction entrances, street cleaning, traffic control, haul routes, staging, and public access protection.
“By others,” allowances, unit prices, assumptions, alternates, and items deliberately left out.
A good sitework comparison asks ugly questions while the numbers are still on paper.
Ask about cut/fill balance, import/export, rock, unsuitable soils, hauling distance, shrink/swell, and moisture conditioning.
Ask who installs, inspects, maintains, repairs, documents, and removes erosion-control measures.
Ask about trenching, bedding, backfill, sleeves, crossings, laterals, testing, utility coordination, and dry-utility interfaces.
Ask about mobilization, permits, inspections, weather, utility release, paving sequence, and phase turnover.
Ask which field conditions, quantity changes, agency requirements, delays, or conflicts trigger added cost.
Normalize inclusions, exclusions, unit prices, allowances, alternates, and assumptions before ranking bids.
A low sitework bid can be a win if it is complete, clear, and executable. It becomes a trap when the missing scope returns later as change orders, delays, compliance problems, utility conflicts, or muddy surprises.
Sitework traps usually wake more than one monster. Dirt, water, utilities, budget, and schedule all talk to each other.
Appears when cut/fill, import/export, pads, slopes, and soil assumptions do not match field reality.
Appears when detention, erosion control, SWPPP logs, inlets, and runoff scope were treated as minor details.
Appears when utility crossings, sleeves, trenching, laterals, and coordination were not truly included or sequenced.
These character pages explain the risks hiding behind sitework numbers.
Dirt quantities, pads, slopes, drainage, and earthwork surprises.
Detention, erosion control, SWPPP, muddy runoff, and stormwater compliance.
Water, sewer, power, telecom, crossings, trench depths, and utility release.
