Obras Públicas
Cuando el cliente que paga un proyecto de construcción es una entidad gubernamental, se aplica toda una capa separada de leyes laborales y de pago, además de las reglas ordinarias para contratistas. Este capítulo explica cómo reconocer un trabajo de obra pública y las obligaciones de salario prevaleciente, registro, nómina, fianzas y seguros que conlleva.

Qué Cuenta como Proyecto de Obra Pública
En términos sencillos, un proyecto de obra pública es trabajo de construcción, alteración, demolición, instalación o reparación que se paga total o parcialmente con fondos públicos. La clasificación no depende de quién es dueño del terreno ni de quién lo contrata, sino del origen del dinero, por lo que un proyecto construido de forma privada puede seguir siendo obra pública si una agencia pública aporta financiamiento. Una vez que un trabajo califica, las reglas de salario prevaleciente y las relacionadas se aplican a casi todos los contratos, con solo una excepción estrecha para los trabajos más pequeños.
When prevailing wage attaches
Esta sección está en inglés por ahora.
La regla
Prevailing wage is owed on every public works contract over $1,000 — work paid for in whole or in part out of public funds — and only projects of $1,000 or less sit outside the rule.
Cuándo aplica — y cuándo no
- What makes a job public works is where the money comes from, not who owns the land: construction, alteration, demolition, installation, or repair work done under contract and paid for in whole or in part out of public funds.
- The line is drawn at over $1,000. A project of exactly $1,000, or less, falls inside the statutory exemption.
- An awarding body that has adopted a DIR-approved labor compliance program may choose not to require prevailing wage on projects of $25,000 or less for construction work, or $15,000 or less for alteration, demolition, repair, or maintenance work. Without that program, the $1,000 line applies.
- Section 1771 applies to work performed under contract; it does not reach work a public agency carries out with its own forces.
Contraste resuelto
| General prevailing-wage threshold (Lab. Code §1771) | over $1,000 |
| Labor-compliance-program exemption, construction work (§1771.5) | $25,000 or less |
| Labor-compliance-program exemption, alteration, demolition, repair, maintenance (§1771.5) | $15,000 or less |
| DIR registration and certified payroll exemption (§1725.5(f)) | $25,000 or less construction; $15,000 or less maintenance |
Confusiones frecuentes
- The $25,000 and $15,000 figures are not the general prevailing-wage threshold, but they are not idle either: they cap the conditional §1771.5(a) election an approved awarding body may make, and the same two figures separately mark the cutoff for DIR registration under §1771.1(n) and §1725.5(f).
- Payment bonds also turn on $25,000 (Civ. Code §9550). That is a bonding rule, not a wage rule.
- "$1,000 or more" and "over $1,000" are not the same sentence; the statute exempts projects of $1,000 or less.

Salario Prevaleciente — Cómo se Fijan las Tarifas
En un trabajo de obra pública cubierto, todo trabajador debe recibir al menos el salario prevaleciente, una tarifa horaria mínima fijada por oficio y por localidad. El Departamento de Relaciones Industriales (DIR) determina estas tarifas examinando los salarios realmente pagados en cada condado para cada oficio, y la tarifa casi siempre es muy superior al salario mínimo estatal o federal ordinario. Cada tarifa tiene dos partes: una tarifa horaria básica en efectivo más un monto de beneficios adicionales que cubre rubros como seguro médico, pensión, capacitación y vacaciones. El contratista debe colocar la determinación de salario aplicable en el sitio de trabajo para que los trabajadores vean lo que se les debe.
Which determination, and what is inside the rate
Esta sección está en inglés por ahora.
La regla
The rate you owe is the DIR determination for that craft and county in force when the work is performed, and it is the basic hourly rate plus the employer fringe payments, not the cash rate alone.
Cuándo aplica — y cuándo no
- General determinations are issued twice a year, on February 22 and August 22, and go into effect ten days later.
- Employer payments for health and welfare, pension, vacation, travel, subsistence, and apprenticeship or other training are a credit against the obligation. Make no such payments and there is no credit, so the whole determination has to reach the worker in cash.
- The awarding body must cause a copy of the director's determination to be posted at each job site.
Contraste resuelto
| General determinations issued | twice a year, February 22 and August 22 |
| When a determination takes effect | ten days after it is issued |
| Which determination governs | the one in force for the craft and locality when the work is performed |
| What the rate is made of | basic hourly rate plus employer fringe payments |
Confusiones frecuentes
- The determination is per craft and per county, not one statewide number.
- Paying the basic hourly rate in cash is not the whole obligation; the fringe amount is part of the rate.
- The DIR sets the rate; the awarding body is the one that has it posted at the job site.

Registro de Contratista ante el DIR
Aparte de la licencia de la CSLB, todo contratista o subcontratista que quiera trabajar en obras públicas debe primero registrarse anualmente ante el DIR y pagar la cuota de registro. El registro debe estar vigente antes de que el contratista presente una oferta y antes de que se adjudique un contrato de obra pública. Una agencia adjudicadora no puede aceptar una oferta de un contratista no registrado ni otorgarle un contrato, por lo que dejar caducar el registro puede dejar a un contratista totalmente fuera de un trabajo público.
DIR registration is not your licence
Esta sección está en inglés por ahora.
La regla
A CSLB licence is not enough for public works: you must also hold a current DIR public works registration, renewed on the annual fiscal-year cycle, to bid, to be listed in a bid, and to perform the work.
Cuándo aplica — y cuándo no
- The fee is $400 for one fiscal year, and you may pay in annual increments up to three years at a time ($800 for two years, $1,200 for three). That prepays the renewals; it is not a one-off lifetime registration.
- Subcontractors register too: registration is what makes a contractor qualified to be listed in a bid proposal under Public Contract Code §4104.
- Registration is not required for work on a public works project of $25,000 or less for construction, alteration, demolition, installation, or repair, or of $15,000 or less for maintenance.
- The director may set and adjust the annual fee up to $800 by publishing it on the department's website, so read the current figure rather than memorising one.
Contraste resuelto
| CSLB licence | issued and renewed through the CSLB; it is what lets you contract at all |
| DIR public works registration | renewed on the annual fiscal-year cycle; it is what lets you bid and work public works |
| Registration fee | $400 for one fiscal year, $800 for two, $1,200 for three |
| Small-project exemption (§1725.5(f)) | $25,000 or less construction; $15,000 or less maintenance |
Confusiones frecuentes
- Registration runs per contractor per year, not per project.
- The DIR registration and the CSLB licence run on separate clocks; renewing one does not renew the other.
- Buying three years at once is prepaying three annual increments, not registering once and for all.

Nómina Certificada y Aprendizaje
Los contratistas de obras públicas deben llevar registros de nómina certificada —registros precisos que muestran el nombre, la clasificación, las horas trabajadas y los salarios pagados de cada trabajador— y presentarlos, generalmente a través del sistema en línea del DIR, ante el Comisionado Laboral. Estos registros prueban que realmente se pagó el salario prevaleciente y deben estar disponibles para inspección. Las obras públicas también conllevan un deber de aprendizaje: el contratista debe emplear aprendices en la proporción correcta y debe solicitar aprendices a un programa de aprendizaje aprobado por el estado para cada oficio aplicable.
The 1:5 apprentice ratio
Esta sección está en inglés por ahora.
La regla
On a public works contract of $30,000 or more you must employ apprentices for at least one hour of apprentice work for every five hours of journeyman work in that craft.
Cuándo aplica — y cuándo no
- The ratio is measured across the contract, not shift by shift: the computed apprentice hours must be worked before the end of the contract.
- Contracts of a general contractor, or of a specialty contractor not bidding through a general or prime contractor, that involve less than $30,000 are outside the section.
- Apprentices come from a state-approved program; ask for them with a DAS 142 dispatch request at least 72 hours (excluding Saturdays, Sundays and holidays) before you need them.
Contraste resuelto
journeyman hours ÷ 5 = the minimum apprentice hours
| The ratio | 1 hour of apprentice work per 5 hours of journeyman work |
| 200 journeyman hours | at least 40 apprentice hours |
| Threshold for the apprenticeship duty | contracts of $30,000 or more |
| How the ratio is measured | cumulatively over the contract, met before it ends |
Confusiones frecuentes
- 1:5 is not one apprentice for every five journeymen on the crew. It counts hours of work, not heads.
- Falling short on a single day is not by itself a violation; the count runs over the whole contract.

Telling the committee, and what a knowing violation costs
Esta sección está en inglés por ahora.
La regla
Before you start work you must send contract award information (the DAS 140) to each applicable apprenticeship committee within ten days of executing the contract, and a knowing second violation of the apprenticeship rules can keep you off public works for up to three years.
Cuándo aplica — y cuándo no
- The ten days run from execution of the prime contract or subcontract, and in no event later than the first day you have workers employed on the public work.
- DAS 140 is the award notice, one per applicable craft. DAS 142 is the later request to dispatch apprentices, at least 72 hours before you need them.
- The project notice to the DIR is the awarding body's filing, within 30 days of the award and no later than the first day a contractor has workers on the public work. It is not the contractor's form.
- The money penalty and the bidding ban live in two different sections: civil penalties in §1777.7, ineligibility to bid in §1777.1.
Contraste resuelto
| DAS 140 contract award information | within 10 days of executing the contract, and before workers are on site |
| DAS 142 dispatch request | at least 72 hours before apprentices are needed |
| Civil penalty for a knowing violation (§1777.7) | up to $100 per day; up to $300 per day for a repeat within three years |
| Ineligibility to bid (§1777.1(d)(1)) | up to 1 year for a first violation; up to 3 years for a second or subsequent |
Confusiones frecuentes
- Section 1777.7 no longer carries the bidding ban. Since it was repealed and re-added in 2014 it sets civil penalties, and the up-to-three-year ineligibility sits in §1777.1(d)(1).
- DAS 140 and DAS 142 are different filings on different clocks, and the DIR project notice belongs to the awarding body.

Where the certified payroll actually goes
Esta sección está en inglés por ahora.
La regla
On a DIR-monitored public works job the payroll records for every worker go to the Labor Commissioner in electronic form at least once every 30 days, not only to the awarding body.
Cuándo aplica — y cuándo no
- The record shows each worker's name, address, social security number, work classification, straight time and overtime hours worked each day and week, and the actual per diem wages paid, and it carries a written declaration under penalty of perjury that the information is true and correct.
- Monthly means at least once every 30 days while work is being performed on the project, and once more within 30 days after the final day of work.
- The format is electronic, in the manner the Labor Commissioner prescribes on the department's internet website.
- Separately from that upload, a certified copy must be made available for inspection or furnished on request to the employee or the employee's representative, to the awarding body, and to the Division of Labor Standards Enforcement.
Contraste resuelto
| Where the records go (§1771.4) | to the Labor Commissioner, electronically, in the manner prescribed on the department's website |
| How often (§1771.4) | at least every 30 days while work continues, and within 30 days of the last day worked |
| Failing to upload (§1771.4) | $100 per day, not to exceed $5,000 per project, and not levied until 14 days after the deadline |
| Failing to produce records on request (§1776(h)) | $100 for each calendar day, for each worker, until strict compliance |
Confusiones frecuentes
- Sending the records to the awarding body is not the whole duty. On a monitored job they also go to the Labor Commissioner.
- Two different $100 penalties. The §1771.4 one runs per day and stops at $5,000 for the project; the §1776(h) one runs per day for each worker until the records are produced.
- Payroll compliance runs to the Labor Commissioner. Neither the county recorder nor the local building official is a recipient of certified payroll.

Fianzas en Obras Públicas
Los contratos de obra pública comúnmente requieren tres tipos de fianzas. Una fianza de oferta, presentada junto con la oferta, garantiza que el contratista firmará el contrato si es seleccionado. Una fianza de cumplimiento, usualmente exigida por la agencia adjudicadora, garantiza que el proyecto se completará conforme al contrato. Una fianza de pago es requerida por ley en contratos de obra pública mayores de $25,000; garantiza que se pagará a los trabajadores, subcontratistas y proveedores de materiales, lo cual importa mucho porque ellos no pueden colocar un gravamen sobre la propiedad pública.
Which bond does what
Esta sección está en inglés por ahora.
La regla
On a public works contract in excess of $25,000 the direct contractor must give a payment bond before work starts, and the bond has to be executed by an admitted surety insurer.
Cuándo aplica — y cuándo no
- The payment bond exists because public property cannot be liened; it stands behind the workers, subcontractors and suppliers who have no lien to record.
- A bid bond, or other bidder's security, is submitted with the bid and guarantees the successful bidder will sign the contract and furnish the required bonds.
- A performance bond is executed by the party awarded the contract for the faithful performance of the contract; it answers to the awarding body, not to the suppliers.
- Admitted surety insurer means a surety company licensed and authorised to transact that business in California. A bank, an insurance agent, or the awarding agency itself cannot stand in for it.
Contraste resuelto
| Payment bond | required over $25,000; guarantees workers, subcontractors and suppliers are paid |
| Performance bond | guarantees faithful performance of the contract |
| Bid bond | guarantees the successful bidder executes the contract |
| Who may issue it | an admitted surety insurer |
Confusiones frecuentes
- The payment bond and the performance bond are both furnished by the prime, but they protect different people.
- The $25,000 figure belongs to the payment bond, not to the prevailing-wage threshold.

Avisos de Suspensión de Pago en Obras Públicas
Como la propiedad pública no puede ser gravada, un contratista o proveedor en un trabajo de obra pública no tiene derecho a registrar un gravamen de constructor: ese recurso simplemente no existe contra el terreno gubernamental. El recurso sustituto es el aviso de suspensión de pago: un reclamante no pagado entrega un aviso por escrito a la agencia pública, la cual debe entonces retener suficientes fondos no pagados del proyecto para cubrir el reclamo hasta que se resuelva la disputa. Junto con la fianza de pago requerida, el aviso de suspensión de pago da a los subcontratistas y proveedores su vía principal para cobrar en proyectos públicos.
The stop payment notice replaces the lien
Esta sección está en inglés por ahora.
La regla
You cannot lien public property, so an unpaid claimant serves a stop payment notice on the public entity to make it hold back project funds, and once a notice of completion, acceptance or cessation is recorded there are 30 days to do it.
Cuándo aplica — y cuándo no
- If no notice of completion, acceptance or cessation is recorded, the window is 90 days after cessation or completion.
- On receipt, the public entity must withhold from the direct contractor funds sufficient to pay the claim stated in the notice, plus its reasonable cost of any litigation.
- Rights against the construction fund on a public works contract are governed exclusively by this chapter; no other legal or equitable theory reaches that fund.
Contraste resuelto
| Notice of completion, acceptance or cessation recorded | 30 days to give the stop payment notice |
| No such notice recorded | 90 days after cessation or completion |
| Action on the payment bond (Civ. Code §9558) | not later than six months after the stop-notice period closes |
| Mechanics lien on the agency's land | not available |
Confusiones frecuentes
- Civil Code §9558 is the deadline for suing on the payment bond. The 30-day and 90-day stop-notice windows are §9356.
- Recording a notice of completion shortens the window from 90 days to 30. It never extends it.

Seguros, Horas Extra y Sanciones
Los trabajos de obra pública conllevan el mismo requisito de seguro de compensación laboral que cualquier otro trabajo de contratista, y las agencias adjudicadoras normalmente exigen comprobante de cobertura de responsabilidad civil general como condición del contrato. Las reglas de horas extra en obras públicas son estrictas: el trabajo de más de ocho horas en un día o cuarenta horas en una semana debe pagarse a la tarifa de horas extra prevaleciente. Violar la ley de salario prevaleciente es costoso: el Comisionado Laboral puede imponer sanciones por cada trabajador por cada día de pago insuficiente, y el contratista también debe pagar la diferencia entre lo pagado y el salario prevaleciente correcto.
Overtime on public works, and the $25 a day it costs to get it wrong
Esta sección está en inglés por ahora.
La regla
Work someone past 8 hours in a day or 40 in a week on a public work without paying at least one and one-half times the basic rate, and you forfeit $25 for that worker for that day on top of the overtime you still owe.
Cuándo aplica — y cuándo no
- It does not matter whether you required the extra hours or merely permitted them, and the forfeiture runs for each calendar day on which it happened.
- Underpaying the prevailing wage is a different violation with a different number: not more than $200 for each calendar day for each worker, set by the Labor Commissioner on good faith and prior record, plus the wage difference.
- Every employer except the state must secure the payment of workers' compensation, on public and private jobs alike.
Contraste resuelto
| Overtime trigger (§1815) | over 8 hours in a day or 40 hours in a week |
| Overtime rate (§1815) | not less than 1.5 times the basic rate of pay |
| Overtime forfeiture (§1813) | $25 per worker per calendar day |
| Prevailing-wage underpayment penalty (§1775) | not more than $200 per worker per calendar day, plus back wages |
Confusiones frecuentes
- $25 and $200 are two different penalties: $25 is the overtime forfeiture, $200 is the ceiling for underpaying prevailing wage.
- Workers' compensation is not a public-works-only requirement; the same coverage is required on private jobs.
