What We Do

Planning, design and construction of underground projects is a complex mixture of client needs, contractual preferences, risk allocation, third party requirements, design criteria and subsurface conditions. Our understanding of those factors is incorporated in each of the services we offer to Create Space Underground.

Pre-Bid Analysis

Brierley Associates has real world experience and knowledge to help Contractors evaluate a project through technical review of the contract documents, risk determination, constructibility assessment, and identification of alternate design concepts to reduce contractor costs. Our geotechnical interpretive reports predict ground behavior as opposed to preparing an overly conservative report designed to avoid litigation. Through this approach we can help you identify the most efficient, reliable and cost effective means and methods for constructing your project.

Services include:

  • Technical Review of Drawings, Specifications, and Reports
  • Interpretation of Subsurface Conditions
  • Means, Methods, and Constructibility Assessments
  • Risk Identification and Evaluation
  • Conceptual Support of Excavation Designs for Costing Purposes
  • Conceptual Design for Costing Purposes
  • Cost Estimates
  • Design of Dewatering Systems
  • Design of Ground Improvement Techniques
  • Instrumentation and Performance Monitoring

Feasibility Studies

Our underground engineers and geologists have seen a lot of different subsurface conditions and many underground technologies. We can help evaluate alignments and construction alternatives to determine the options that best suit the work from our client’s perspective.

Services include:

  • Search and evaluation of existing geological information
  • Identification of successful local underground construction practices
  • Reviewing possible third party impacts
  • Geological Investigations
  • GDRs and GBRs
  • Conceptual Designs
  • Contract Drawings and Specifications
  • Cost Estimates and Schedules
  • Risk Assessment

Value Engineering

Value engineering (VE) is defined as a systematic method to improve the “value” of goods or products and services by using an examination of function. Value, as defined, is the ratio of function to cost. Value can therefore be increased by either improving the function or by reducing cost. Brierley Associates has been a contributor and team member for VE efforts since our company’s inception. We help designers and contractors by integrating the VE process during the early stages of a project so that maximum benefits can be realized.

Design-Build Services

Brierley Associates is a leader in the implementation of subsurface Design-Build projects. Our Founder and our Partners have written numerous papers and texts on the subject of Design-Build for subsurface construction projects. When implemented correctly, Design-Build offers many advantages over conventional Design-Bid-Build projects such as, single point responsibility, increased cooperation between engineer and contractor, and potentially the reduction in project cost and schedule.

Services include:

  • Subsurface Exploration and Reporting
  • Geotechnical and Geological Engineering
  • Analysis and Design
  • Preparation of Drawings and Specifications
  • Preparation of Submittals
  • Construction Management

Design

Brierley Associates underground engineering staff understands the importance of anticipating ground behavior through comprehensive geotechnical investigations geared specifically toward design of underground structures. We also understand how critical it is to communicate this information through appropriate construction contract documents including Geotechnical Data Reports (GDRs), Geotechnical Baseline Reports (GBRs), drawings, and specifications. Correct geotechnical investigations, design, and contracting methods will help to fairly allocate risk between parties, and thereby, generate good quality bids for owners and minimize the risk of differing site conditions and cost overruns.

Construction Support Services

Brierley Associates is positioned to support you on your construction project whether it is a large public infrastructure or a small private project. We work with Contractors before, during, and after construction. The key to success for any underground construction project is understanding ground behavior, if you can properly predict how the ground will behave and how it will interact with the construction methods chosen, then you are on your way to a successful project. Brierley Associates can provide a wide range of technical support to a specific project, drawing from a talent pool of engineers, geologists and construction personnel to tackle the most challenging underground projects.

Services include:

  • Submittal Review
  • Construction Monitoring
  • Differing Site Conditions Evaluation
  • Costs and Schedules
  • Contract Documentation
  • Instrumentation Installation and Monitoring

Forensic Engineering, Claims, and Dispute Resolution

Brierley Associates provides forensic engineering services requiring expertise in geotechnical engineering, heavy construction, tunneling, and trenchless pipeline construction. We offer the ethics and integrity of the firm’s founders and senior staff with their combined experience of over 300 years in heavy civil construction. We adhere to the principle that a good forensic engineering expert is a detective, one who patiently searches for evidence and reconstructs events in order to reach unbiased conclusions that will stand the scrutiny of peers and cross-examination by attorneys. We follow a disciplined approach; determining an absence of conflicts of interest, hearing the nature of the assignment, accepting the assignment, careful assembly and active review of pertinent information, proactive analysis, and development of conclusions and opinions.
