Post Design and Construction Management

Yeh and Associates provides engineering services after design and during construction. We have participated in both formal and informal value engineering reviews. Our review of the Beartooth Road design provided alternate construction techniques that significantly decreased the construction costs and brought the project back into budget. We also provide post design services for project scheduling, proposal review, attendance at pre-construction meetings.

During construction, Yeh’s professional services include materials and design RFI submittal response, Certificate of Compliance (COC’s) review, shop drawing and false work review and claims resolution. New and innovative materials and construction procedures are often proposed in RFIs and sometimes used on projects. As such, there is a need for an engineering evaluation of these products to determine if they will perform as intended. Another possibility is that a proposed material or process might need an engineering analysis or preliminary testing to determine if the material in question would serve the intended purpose. An analysis of material testing such as soils or stockpiled aggregate might also be required to determine if a material is appropriate for use on a project. Yeh has the expertise to research, test, and evaluate most standard construction materials used on the projects.

Successful implementation of project designs through the construction process requires trained and experienced construction management and engineering staff. Yeh and Associates staff have provided construction engineering services to our clients for a variety of projects with wide ranges in size and complexity.

We can provide a construction engineering staff to suit nearly any arrangement a client may desire from project construction management to specific materials testing. We are experienced in both conventional bid-build project delivery and modern design build projects. Our personnel can supplement your project staff in a seamless transparent manner or we can provide a fully-staffed construction engineering team, including resident/project engineers, inspectors and field technicians.

Our staff of field-testing technicians and inspectors provides quality control/quality assurance materials testing for projects of varying size and complexity. Our technicians are trained and certified to provide a full range of field material testing services, including nuclear testing for soil density/moisture, pavement density control, asphalt content, and concrete design compliance.

Yeh and Associates has in-house materials testing laboratories located in the Denver, Durango and Glenwood Springs. These labs are fully equipped and staffed with trained, certified personnel. Licensed professional engineers oversee our laboratory testing. The laboratories are capable of performing rock and soil properties tests, and an array of asphalt, concrete, masonry, and steel tests. Our Denver laboratory is AASHTO certified for soil, concrete and asphalt testing.

Yeh and Associates provides geotechnical instrumentation services, both during and after construction, tailored to fit the specific requirements of your project. We utilize a variety of instrumentation methods to measure conditions such as settlement, lateral movement and distortion structures, soil and rock slope movement, subsurface water levels and pressures, soil pressure and foundation response.

Our staff can provide a full-service instrumentation package including the planning, design, procurement, installation, monitoring and data collection, and reporting. We are experienced in the use of inclinometers, settlement gauges, tilt meters, tape and borehole extensometers, joint meters, load cells, piezometers, and time domain reflectrometry (TDR).

Our instrumentation installations are designed to best accommodate our client’s needs. We are skilled in designing and providing continual data collection through remote data acquisition units or reading instruments conventionally by regular visits by our staff.
